The objective of this study is to investigate orchard maintenance and post-harvest cocoa treatment practices used by cocoa farmers in infiltrated classified and unclassified areas of Méagui. To do this, 110 producers in two localities of the said zone were individually interviewed from February to April 2022, using a declarative questionnaire. It was found that cocoa orchards in the zone are aging. Nearly 68.55% of producers were heirs and 58.33% of those interviewed were under 46 years of age, with an average age of 43 years. Nearly 84.55% of the producers surveyed mainly use chemical insecticides to control the pests of greatest concern in these localities. Regarding the frequency of insecticide treatments, 11.82% of producers make 1 to 2 applications a year, 29.09% make 3 to 5 applications a year, and 43.64% make at least 6 applications a year. The active substances of the most used products belong to 99% of the Neonicotinoid and Pyrethroid families. Regarding cocoa harvesting and post-harvest operations, 93.64% of the producers carry out a single harvest/month;all do the shelling with mini machetes. Beans are fermented mainly in black plastic tarpaulins or in bags, for a period of 3 to 5 days (65.45%). Drying is done almost entirely (91.82%) on the black plastic tarp. This study shows that cocoa farmers in the areas surveyed do not respect the recommendations issued on phytosanitary practices and post-harvest treatment of cocoa. This non-compliance with the standards of good practices prescribed is particularly more accentuated in the locality located in infiltrated classified zone. It would, therefore, be judicious to revise or redefine the phytosanitary recommendations and carry out sensitization and training-follow-up programs for producers in this important cocoa production area of C?te d’Ivoire.展开更多

In Zambia, there is little information documented regarding the knowledge, attitude, and practices of poultry farmers on AMU and AMR. Therefore, this study assessed the knowledge, attitude and practices regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Methods: This was a cross-sectional study conducted among 106 poultry farmers from November to December 2021 using a structured questionnaire. Data analysis was done using IBM Statistical Package for Social Sciences (SPSS) version 26. Results: Overall, of the 106 participants, 90.6% knew what antimicrobials were, but only 29.2% were aware of AMR. The study showed that 46.2% of the participants had low knowledge, 71.7% had negative attitudes, and 61.3% had poor practices regarding AMR. The prevalence of antibiotic use in poultry production was 83%. The most used antimicrobials were tetracycline (84%) and gentamicin (35.2%). The commonly reported reason for the use of antimicrobials was for the treatment (93.2%) and prevention (89.8%) of diseases. Further, 76.9% of the administered antimicrobials were usually done without veterinarian consultation or prescription. Conclusion: The study shows that there was high AMU in poultry farms in Kitwe. However, there was low knowledge, negative attitude, and poor practices towards AMU and AMR. Therefore, there is a need for educational and sensitisation programmes regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Alongside this, antimicrobial stewardship and surveillance systems should be strengthened in the livestock production sector. This will ensure food safety and public health.展开更多

Sloping land in South China has experienced a decline in crop productivity by 30-60% due to soil erosion and it has been predicted that most topsoil will be lost within the next 100 years if current erosion rates continue. Considering these situations, an agro-environmental research and development project (Sustainable Highland Agriculture in South-East Asia- SHASEA) was conducted in a catchment in Yunnan Province, China, to address the objectives of increasing crop productivity in sustainable and environmentally-friendly ways. A range of cropping practices was developed and implemented in a rural upland catchment (Wang Jia). At the end of the project, farmers were surveyed to evaluate project effectiveness. All farmers from Wang Jia Catchment, who were involved in project implementation, were surveyed. A sample of farmers working in an adjacent catchment (not associated with the project) was surveyed for comparative purposes. Farmers had different perceptions of the cropping practices employed. Contour cultivation was preferred and likely to be adopted. Others practices such as straw mulching and intercropping were seen as less appropriate and unlikely to be adopted. Polythene mulch was recognized as effective, but likely to be adopted only if financial returns were favourable. The availability of relevant information had an important impact on the extent of technology testing by farmers and their willingness to adopt the practices in the future.展开更多

This study was carried out to assess the implications of some agronomic practices on the infestation of aflatoxigenic fungi and total aflatoxin in maize produce in Benue State. Two maize sample types (Pre-harvest and Post-harvest) collected from 3 locations in Benue State were cultured on Sabouraud dextrose agar for fungi isolation and identification. Moisture content and total aflatoxin concentration were determined (ELISA method) in both pre-harvest oven dried and farmer’s post-harvest sun dried samples. Information on agronomic practices was obtained with the aid of questionnaire. T-test and analysis of variance (ANOVA) were used to analyze the data with confident levels set at 95%. Overall, 5 mould genera were identified: Aspergillus (44.0%), Fusarium (24.44%), Botryodiplodia (17.78%), Rhizopus (15.56%) and Penicillium (4.44%). Moisture content of oven dried samples was significantly less than that of farmers sun dried samples (t = 10.45, P < 0.001). Similarly, a significant difference in total aflatoxin concentration was recorded between farmers sun dried and oven dried samples (t = 2.37, P = 0.03). Half of the farmer’s sun dried samples had aflatoxin concentration above the recommended EU (4 ug/Kg) limit, but none of the pre-harvest oven dried samples exceeded EU limits. Maize samples from fertilized farms were more likely than non-fertilized farms to have higher aflatoxin concentration (P = 0.002). Similarly, Maize seeds purchase from the open market were more likely than seeds from previous harvest to be contaminated with aflatoxin (P = 0.003). The study advocates rapid drying of timely harvested maize so as to reduce or stop the action of heavy field fungi contaminants as well as aflatoxin accumulation.展开更多

A survey methodology was employed using a random sample of 25 Farmer Field School (FFS) members and 5 non=FFS members from each of the five locations of Marigat Division. In total, 100 FFS members and 25 non-FFS members participated in the study; addi- tional supplementary data were collected from the Kenya Forestry Research Institute (KEFRI), a major facilitator and trainer of the identified FFS activities and practices in the study area since 2004. More than 80% of the local community never undertook any form of prosopis management practice; however, this changed after FFS training, indicating an acquisition and retention of knowledge which probably diffused to the non-FFS counterparts, through either formal or informal ways. Harvesting was the most preferred (100%) and stump burning the least preferred (46%) practice of managing the spread of prosopis. The success and preference of any prosopis management practice was attributed to wood and non-wood benefits derived from prosopis and growing of animal fodder and food crops on rehabilitated land. More than 80% of respondents attributed ineffectiveness of any prosopis management practice to coppicing and viable seed banks of the tree, while 50% highlighted a lack of consistency and integration in carrying out manage- ment practices. The reported negative attitude towards prosopis changed after training with none of the view to eradicate it. Labor intensity and frequent regeneration of seedlings were identified as the major challenges faced during the implementation of proso- pis management practices. In conclusion, the study shows that harvesting, uprooting, stump burning, pruning and thinning realized through consistent holistic integration contribute to containing the spread of prosopis trees in Baringo, Kenya.展开更多

As the rubber plantation area increases yearly, the requirement of vigorous rubber seedlings for its establishment plays a central role. The success of rubber plantations depends on some farming practices such as using different compost or other materials in the potting soil-medium, varietal selection for stock and scion in the budding process, and fertilizer application methods. The objective of this study was to assess the farmer’s practices in the establishment of rubber nurseries in mostly rubber planted areas in Myanmar. The survey interviewed 60 respondents from three townships in Mon State, namely Mudon, Kyaikmaraw, and Thanbyuzayat. The response data were analyzed through the descriptive method. This survey exposed the potentially active operators (middle age of 30 - 60 years) in rubber nursery production. Local experienced farmers usually raised the budded seedlings with 15 cm × 23 cm polyethylene bag in all study regions. Most farmers selected multi-clonal seed for stock and BPM 24 for scion according to the local market demand and high latex yield. All survey areas used both organic and inorganic fertilizers for nutrient management. Compost is a chief component of growing medium in their nursery production. However, making compost and high demand of the compost were local constraints. Therefore, this survey suggested improving the proper composting method for rubber nursery establishment.展开更多

This practice is common, especially among smallholder farmers (SHFs). There is no updated record of commonly used waste management practices. Our study focused on smallholder farmers in two farming systems in Masaka and Lyantonde Districts respectively, and with the objective to determine smallholder waste management practices in relation to farm waste components. Using a sample survey, quantitative data were collected from 120 SHFs representing 10.1% of the total SHF population in the Masaka while 120 SHFs provided data and represented 17.4% of the total SHF population in Lyantonde. Our result revealed that for animal waste, Goat slurry 20.4%, dominated the rest in Lyantonde, while in Masaka Pig slurry 23.6%, was dominant. For crop waste in Lyantonde, Bean trashes 12.9%, dominated, while in Masaka Banana leaves and peelings 11.1%, were dominant. In Lyantonde, common waste management practices were: Surface deposition 41.2%, Burning 18.4% Composting 17.3%, Burying 9.4%, Removal 10.9% and Recycling 2.8%. In Masaka, common practices were: Surface deposition 40.9%, Burning 18.6% Composting 13.2%, Burrying 12.3%, Removal 6.2% and Recycling 8.8%. Factors affecting choice of waste management practices by SHFs were: Age, purpose of waste product, season, quantity of the wastes, waste management policy awareness, farmer’s commitment and economic status of the farmer. Greenhouse gas emission for identified waste management practices across the two Districts shall be determined in our next study.展开更多

This study aimed to assess the knowledge and practices, in terms of pig biosecurity measures, of individual stakeholders involved in pig production in rural and peri-urban households in Cambodia. A survey tool was developed and administered using Kobotoolbox, an online electronic survey tool. Surveys were conducted in the provinces of Kampong Thom, Siem Reap, and Battambang during December 2017 to September 2018. There were 225 pig farmers, 43 village animal health workers (VAHWs), 3-district veterinarians (DVs), and 81 feed store owners enrolled in the study. Results showed that several biosecurity guidelines are not followed or well understood by farmers. Specific concerning practices included using natural boars, sharing pig equipment (e.g. scales), feeding kitchen waste, managing other livestock, handling manure, and not restricting access by visitors (VAHWs or DVs, boar owners, pig buyers, neighbors, and meat sellers). Thus, education of pig smallholder farmers and VAHWs on pig biosecurity is needed for improving pig health and production, economic value, and livelihood of smallholder farmers in Cambodia.展开更多

Previous surveys confirmed that coffee grown in central Uganda was largely depending on bee pollination to set fruit set. Despite its high contribution to the economics of agricultural sector in Uganda and despite its great dependency to bees for fruit set, it is not clear if small-scale farmers are aware of the importance of managing farm-landscapes for pollination services conservation to increase coffee yield. The aim of this study was to assess farmers’ perceptions and knowledge of the importance of pollinators and pollination services conservation for coffee production enhancement. The main hypothesis was that small-scale coffee growers were not aware of the relevance of pollination services for coffee production. Farmers’ surveys were conducted in coffee-banana farming systems in central Uganda. It was found in this study that more than 90% of interviewed farmers were not aware of the role played by bees in coffee yield increase. Farmers were not willing to manage their lands to protect pollination services, particularly because they considered pollination service as an unsolicited “free service”, or as a “public good”. Farmers were not aware of the role of semi- natural habitats serving as reservoir (hiding points) for pollinators in the surrounding of coffee fields. However, they were aware of some ecosystem services delivered in the coffee- banana farming system such as planting shading trees. Only 3.3% of respondents believed that placing beehives in coffee farms could increase the yield. The study recommended the increase of the awareness of small-scale coffee growers on the importance of pollinators to increase coffee production. It is recommended that future management of pollination services are built on improving farmers’ indigenous knowledge and on adequate understanding of the ecology of the local pollinator species. There is a need to broadly scale-up best field, habitat and landscape management strategies and practices that are friendly to coffee pollinators in rural landscapes of展开更多

This study evaluates the practices of nutrient fertilizer input by farmers and researchers and relates them to their corresponding yields and profit so as to establish the appropriateness of the practices in 13 districts of the Northern regions of Ghana. Soil nutrients assessment of Nitrogen (N), Phosphorus (P) and Potassium (K) contents used to evaluate the soil NPK status was based on previous studies. Data on fertilizer application by farmers and researchers were obtained from the Savanna Agricultural Research Institute (SARI). The amount of N, P and K fertilizer input in 13 Districts and its associated maize grain yields by both farmers (89) and researchers were calculated and compared using two-sample t-test. The t-test results indicated that average amount of fertilizer input by researchers was significantly (p < 0.05) higher than the average amount of fertilizer input by the smallholder farmers, but the high fertilizer input did not significantly (p = 0.74) increase researchers’ maize yields and profits in all 13 study districts grouped together, but there was maize increment in only eight districts. On the average, farmers from five districts applied low fertilizer and recorded low yields. However, when researchers increased quantities of fertilizer applied in these five districts, yield significantly (p < 0.05) increased. The outcome showed that smallholder farmers in these five districts could increase maize yields by 36% in the region should they adopt the maize production strategy by the researchers. The study concluded that, for best options, recommended fertilizer doses to enhance maize yields should consider district-specific farmers’ practices and soil NPK status. The study could enable better implementation of location-based nutrient recommendation in the Northern Region of Ghana.展开更多

文摘An important part of Ivorian cocoa production comes from infiltrated classified forests. The objective of this study is to investigate orchard maintenance and post-harvest cocoa treatment practices used by cocoa farmers in infiltrated classified and unclassified areas of Méagui. To do this, 110 producers in two localities of the said zone were individually interviewed from February to April 2022, using a declarative questionnaire. It was found that cocoa orchards in the zone are aging. Nearly 68.55% of producers were heirs and 58.33% of those interviewed were under 46 years of age, with an average age of 43 years. Nearly 84.55% of the producers surveyed mainly use chemical insecticides to control the pests of greatest concern in these localities. Regarding the frequency of insecticide treatments, 11.82% of producers make 1 to 2 applications a year, 29.09% make 3 to 5 applications a year, and 43.64% make at least 6 applications a year. The active substances of the most used products belong to 99% of the Neonicotinoid and Pyrethroid families. Regarding cocoa harvesting and post-harvest operations, 93.64% of the producers carry out a single harvest/month;all do the shelling with mini machetes. Beans are fermented mainly in black plastic tarpaulins or in bags, for a period of 3 to 5 days (65.45%). Drying is done almost entirely (91.82%) on the black plastic tarp. This study shows that cocoa farmers in the areas surveyed do not respect the recommendations issued on phytosanitary practices and post-harvest treatment of cocoa. This non-compliance with the standards of good practices prescribed is particularly more accentuated in the locality located in infiltrated classified zone. It would, therefore, be judicious to revise or redefine the phytosanitary recommendations and carry out sensitization and training-follow-up programs for producers in this important cocoa production area of C?te d’Ivoire.
文摘Introduction: The inappropriate antimicrobial usage (AMU) in chicken production has led to an increase in the prevalence of antimicrobial resistance (AMR). In Zambia, there is little information documented regarding the knowledge, attitude, and practices of poultry farmers on AMU and AMR. Therefore, this study assessed the knowledge, attitude and practices regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Methods: This was a cross-sectional study conducted among 106 poultry farmers from November to December 2021 using a structured questionnaire. Data analysis was done using IBM Statistical Package for Social Sciences (SPSS) version 26. Results: Overall, of the 106 participants, 90.6% knew what antimicrobials were, but only 29.2% were aware of AMR. The study showed that 46.2% of the participants had low knowledge, 71.7% had negative attitudes, and 61.3% had poor practices regarding AMR. The prevalence of antibiotic use in poultry production was 83%. The most used antimicrobials were tetracycline (84%) and gentamicin (35.2%). The commonly reported reason for the use of antimicrobials was for the treatment (93.2%) and prevention (89.8%) of diseases. Further, 76.9% of the administered antimicrobials were usually done without veterinarian consultation or prescription. Conclusion: The study shows that there was high AMU in poultry farms in Kitwe. However, there was low knowledge, negative attitude, and poor practices towards AMU and AMR. Therefore, there is a need for educational and sensitisation programmes regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Alongside this, antimicrobial stewardship and surveillance systems should be strengthened in the livestock production sector. This will ensure food safety and public health.

文摘Problems associated with land degradation are serious in China. Sloping land in South China has experienced a decline in crop productivity by 30-60% due to soil erosion and it has been predicted that most topsoil will be lost within the next 100 years if current erosion rates continue. Considering these situations, an agro-environmental research and development project (Sustainable Highland Agriculture in South-East Asia- SHASEA) was conducted in a catchment in Yunnan Province, China, to address the objectives of increasing crop productivity in sustainable and environmentally-friendly ways. A range of cropping practices was developed and implemented in a rural upland catchment (Wang Jia). At the end of the project, farmers were surveyed to evaluate project effectiveness. All farmers from Wang Jia Catchment, who were involved in project implementation, were surveyed.

文摘Several studies in Ethiopia have shown a high prevalence of reproductive disorders(RDs)in dairy cows.However,there is a lack of information about the levels of knowledge among farming community about the causes associated with RDs.A questionnaire-based cross-sectional study design was administered to 278 livestock farmers(LFs)in the Kembata Tambaro zone to evaluate knowledge and preventive practices on infectious causes of RDs in dairy cows.The results show that almost all farmers had heard about RDs,but more than half did not realize that reproductive system infections(RSIs)could cause RDs in dairy cows.A significant number of participants were not aware of the spread of RSIs between animals through sharing of breeding bulls,ingestion of urine contaminated feed,unhygienic management,sharing of equipment between milking cows,and interactions with contagious animals.The majority of LFs reported that they frequently consulted with traditional healers regarding the treatment of RDs,but very few looked for veterinary assistance.The results of multivariable logistic regression analysis showed that level of education and living areas were factors significantly and positively associated with knowledge about RSIs.Likewise,occupation,level of education and being knowledgeable about RSIs were significantly associated with good preventive practices.Veterinarians and responsible authorities should take these results into consideration to educate farmers on preventing losses attributed to RSIs.
文摘This research was carried out to evaluate the preference and adoption of harvesting, uprooting, stump burning, pruning and thinning practices for controlling the spread ofProsopisjuliflora (prosopis) within Marigat Division of the Baringo District, Kenya. A survey methodology was employed using a random sample of 25 Farmer Field School (FFS) members and 5 non=FFS members from each of the five locations of Marigat Division. In total, 100 FFS members and 25 non-FFS members participated in the study; addi- tional supplementary data were collected from the Kenya Forestry Research Institute (KEFRI), a major facilitator and trainer of the identified FFS activities and practices in the study area since 2004. More than 80% of the local community never undertook any form of prosopis management practice; however, this changed after FFS training, indicating an acquisition and retention of knowledge which probably diffused to the non-FFS counterparts, through either formal or informal ways. Harvesting was the most preferred (100%) and stump burning the least preferred (46%) practice of managing the spread of prosopis. The success and preference of any prosopis management practice was attributed to wood and non-wood benefits derived from prosopis and growing of animal fodder and food crops on rehabilitated land. More than 80% of respondents attributed ineffectiveness of any prosopis management practice to coppicing and viable seed banks of the tree, while 50% highlighted a lack of consistency and integration in carrying out manage- ment practices. The reported negative attitude towards prosopis changed after training with none of the view to eradicate it. Labor intensity and frequent regeneration of seedlings were identified as the major challenges faced during the implementation of proso- pis management practices. In conclusion, the study shows that harvesting, uprooting, stump burning, pruning and thinning realized through consistent holistic integration contribute to containing the spread of prosopis trees in Baringo, Kenya.
文摘Rubber is an economically important perennial crop in Myanmar for latex production. As the rubber plantation area increases yearly, the requirement of vigorous rubber seedlings for its establishment plays a central role. The success of rubber plantations depends on some farming practices such as using different compost or other materials in the potting soil-medium, varietal selection for stock and scion in the budding process, and fertilizer application methods. The objective of this study was to assess the farmer’s practices in the establishment of rubber nurseries in mostly rubber planted areas in Myanmar. The survey interviewed 60 respondents from three townships in Mon State, namely Mudon, Kyaikmaraw, and Thanbyuzayat. The response data were analyzed through the descriptive method. This survey exposed the potentially active operators (middle age of 30 - 60 years) in rubber nursery production. Local experienced farmers usually raised the budded seedlings with 15 cm × 23 cm polyethylene bag in all study regions. Most farmers selected multi-clonal seed for stock and BPM 24 for scion according to the local market demand and high latex yield. All survey areas used both organic and inorganic fertilizers for nutrient management. Compost is a chief component of growing medium in their nursery production. However, making compost and high demand of the compost were local constraints. Therefore, this survey suggested improving the proper composting method for rubber nursery establishment.
文摘With diversity in farming systems, crop residues, animal wastes and management practices are often not well managed, and most of it is left on the soil surface. This practice is common, especially among smallholder farmers (SHFs). There is no updated record of commonly used waste management practices. Our study focused on smallholder farmers in two farming systems in Masaka and Lyantonde Districts respectively, and with the objective to determine smallholder waste management practices in relation to farm waste components. Using a sample survey, quantitative data were collected from 120 SHFs representing 10.1% of the total SHF population in the Masaka while 120 SHFs provided data and represented 17.4% of the total SHF population in Lyantonde. Our result revealed that for animal waste, Goat slurry 20.4%, dominated the rest in Lyantonde, while in Masaka Pig slurry 23.6%, was dominant. For crop waste in Lyantonde, Bean trashes 12.9%, dominated, while in Masaka Banana leaves and peelings 11.1%, were dominant. In Lyantonde, common waste management practices were: Surface deposition 41.2%, Burning 18.4% Composting 17.3%, Burying 9.4%, Removal 10.9% and Recycling 2.8%. In Masaka, common practices were: Surface deposition 40.9%, Burning 18.6% Composting 13.2%, Burrying 12.3%, Removal 6.2% and Recycling 8.8%. Factors affecting choice of waste management practices by SHFs were: Age, purpose of waste product, season, quantity of the wastes, waste management policy awareness, farmer’s commitment and economic status of the farmer. Greenhouse gas emission for identified waste management practices across the two Districts shall be determined in our next study.
文摘Biosecurity measures are essential for protecting pig health, however, these practices are not always utilized by smallholder farmers in Cambodia. This study aimed to assess the knowledge and practices, in terms of pig biosecurity measures, of individual stakeholders involved in pig production in rural and peri-urban households in Cambodia. A survey tool was developed and administered using Kobotoolbox, an online electronic survey tool. Surveys were conducted in the provinces of Kampong Thom, Siem Reap, and Battambang during December 2017 to September 2018. There were 225 pig farmers, 43 village animal health workers (VAHWs), 3-district veterinarians (DVs), and 81 feed store owners enrolled in the study. Results showed that several biosecurity guidelines are not followed or well understood by farmers. Specific concerning practices included using natural boars, sharing pig equipment (e.g. scales), feeding kitchen waste, managing other livestock, handling manure, and not restricting access by visitors (VAHWs or DVs, boar owners, pig buyers, neighbors, and meat sellers). Thus, education of pig smallholder farmers and VAHWs on pig biosecurity is needed for improving pig health and production, economic value, and livelihood of smallholder farmers in Cambodia.
文摘Coffee (Coffea canephora) is the principal cash crop and the country’s largest agricultural foreign revenue earner in Uganda. Previous surveys confirmed that coffee grown in central Uganda was largely depending on bee pollination to set fruit set. Despite its high contribution to the economics of agricultural sector in Uganda and despite its great dependency to bees for fruit set, it is not clear if small-scale farmers are aware of the importance of managing farm-landscapes for pollination services conservation to increase coffee yield. The aim of this study was to assess farmers’ perceptions and knowledge of the importance of pollinators and pollination services conservation for coffee production enhancement. The main hypothesis was that small-scale coffee growers were not aware of the relevance of pollination services for coffee production. Farmers’ surveys were conducted in coffee-banana farming systems in central Uganda. It was found in this study that more than 90% of interviewed farmers were not aware of the role played by bees in coffee yield increase. Farmers were not willing to manage their lands to protect pollination services, particularly because they considered pollination service as an unsolicited “free service”, or as a “public good”. Farmers were not aware of the role of semi- natural habitats serving as reservoir (hiding points) for pollinators in the surrounding of coffee fields. However, they were aware of some ecosystem services delivered in the coffee- banana farming system such as planting shading trees. Only 3.3% of respondents believed that placing beehives in coffee farms could increase the yield. The study recommended the increase of the awareness of small-scale coffee growers on the importance of pollinators to increase coffee production. It is recommended that future management of pollination services are built on improving farmers’ indigenous knowledge and on adequate understanding of the ecology of the local pollinator species. There is a need to broadly scale-up best field, habitat and landscape management strategies and practices that are friendly to coffee pollinators in rural landscapes of

文摘Through a large number of literature studies and field survey,from the perspective of small farmers’integration into agricultural modernization,this paper innovatively divided the current integration mode of national agricultural organizations into five main types:leading enterprises,leading new agricultural business entities,cooperative financial institutions,embedded scientific research institutes,and financial poverty alleviation and assistance.It found that Ningxia region can gradually carry out horizontal integration and extension in the process of promoting the vertical integration and extension of agricultural industry value chain,and try to explore the possibility of new integration mode such as"modern agricultural cloud service public platform+leading enterprises+farmers"in Ningxia,in order to bridge the gaps in agricultural organization policies through the pilot,because the village plans to plan the development of the industry,adapt to the local conditions to strengthen the village collective economy,and continuously improve the degree of farmers’organization.
文摘Most research-based fertilizer inputs proposed for small scale farmers to increase their productivity do not achieve the required results and should consider indigenous practices. This study evaluates the practices of nutrient fertilizer input by farmers and researchers and relates them to their corresponding yields and profit so as to establish the appropriateness of the practices in 13 districts of the Northern regions of Ghana. Soil nutrients assessment of Nitrogen (N), Phosphorus (P) and Potassium (K) contents used to evaluate the soil NPK status was based on previous studies. Data on fertilizer application by farmers and researchers were obtained from the Savanna Agricultural Research Institute (SARI). The amount of N, P and K fertilizer input in 13 Districts and its associated maize grain yields by both farmers (89) and researchers were calculated and compared using two-sample t-test. The t-test results indicated that average amount of fertilizer input by researchers was significantly (p < 0.05) higher than the average amount of fertilizer input by the smallholder farmers, but the high fertilizer input did not significantly (p = 0.74) increase researchers’ maize yields and profits in all 13 study districts grouped together, but there was maize increment in only eight districts. On the average, farmers from five districts applied low fertilizer and recorded low yields. However, when researchers increased quantities of fertilizer applied in these five districts, yield significantly (p < 0.05) increased. The outcome showed that smallholder farmers in these five districts could increase maize yields by 36% in the region should they adopt the maize production strategy by the researchers. The study concluded that, for best options, recommended fertilizer doses to enhance maize yields should consider district-specific farmers’ practices and soil NPK status. The study could enable better implementation of location-based nutrient recommendation in the Northern Region of Ghana.
文摘By investigating the problem of farmers’ entrepreneurship in Gongcheng Yaozu Autonomous County,lying in Guilin,Guangxi,the thesis expounds the existing problems impacting farmers’ successful entrepreneurship in minority areas as follows:firstly,the musty idea of local cadre is obstacle to farmers’ successful entrepreneurship;secondly,the problems of scattered farmers’ entrepreneurship resources,waste and shortage of resources impact good effect of entrepreneurship;thirdly,farmers lack awareness of characteristics and brand,influencing the market competitiveness of products;fourthly,the existence of smallholder consciousness critically hampers the marketization and internationalization of entrepreneurship accomplishments;fifthly,the government pays no attention to the construction of industrial chain,which makes farmers’ entrepreneurship lack sustainability.Based on these,corresponding countermeasures are put forward to promote farmers’ successful entrepreneurship in minority areas as follows:firstly,we should update local leaders’ ideas and emphasize the positive role of farmers’ successful entrepreneurship in county economic development;secondly,we should integrate local entrepreneurship resources and promote the efficiency of farmers’ entrepreneurship;thirdly,we should foster the consciousness of brand and characteristics and strengthen the market competitiveness of entrepreneurship accomplishments;fourthly,we should strengthen the construction of industrial chain to promote sustainable development of farmers’ entrepreneurship.
