[Conclusion] Soaking vegetable seeds with liquid seaweed bio-organic fer- tilizer can significantly improve seed generation rate and seedling growth.

Effects of Bio-organic Fertilizer with Antagonistic Bacteria against Tobacco Bacterial Wilt on Soil Microbial Communities and Disease Resistance of Tobacco

In this study, the effects of bio-organic fertilizer with antagonistic bacteria against tobacco bacterial wilt on soil microbial communities and disease resist- ance of tobacco were investigated by field experiment. The results showed that the incidence of tobacco bacterial wilt in bio-organic fertilizer treatments （T3 and T4） decreased remarkably among four treatments in the field. Compared with the local conventional fertilization group, the incidence of tobacco bacterial wilt was re- duced by 21.9% and 25.0% in T3 and T4, respectively ; the yield of flue-cured tobacco was improved by 5.7% and 5.3%, respectively ; the proportion of mid- high grade tobacco leaves increased by 2.3% and 2.6%, respectively. After application of bio-organie fertilizer with antagonistic bacteria against tobacco bacterial wilt, rhizosphere soil microbial communities exhibited vast amount and abundant species ; the amount of rhizosphere soil bacteria of infected tobacco plants was im- proved by 218.5% with fewer species. It could be concluded that the application of bio-organic fertilizer with antagonistic bacteria against tobacco bacterial wilt could improve the ecological environment of tobacco field, inhibit the growth of pathogenic bacteria, decrease the incidence of tobacco bacterial wilt, and enhance the quality of flue-cured tobacco. This study laid the foundation for further ecological prevention and control of soil-borne diseases of tobacco.

Effects of Partial Replacement of Chemical Fertilizer by Bio-organic Fertilizer Kunyijian on Yield and Quality of Tobacco Leaves

To explore the application effect of bio-organic fertilizer Kunyijian in flue-cured tobacco and provide scientific basis for its application in production,a plot trial was conducted with K326,a flue-cured tobacco variety,in the Science and Technology Test Base of Xundian County,Yunnan.Taking local fertilizer consumption(control 1)and 70%local fertilizer consumption(control 2)as controls,the following replacement groups were designed:under uniformly replacement 70%local fertilizer consumption,(i)organic fertilizer∶microbial agent=80∶1(kg),+600 kg/ha,+900 kg/ha,+1200 kg/ha,+1500 kg/ha Kunyijian;(ii)organic fertilizer∶microbial agent=40∶1(kg),+900 kg/ha Kunyijian.The results show that in the treatment of 70%local fertilizer consumption+1200 kg/ha Kunyijian[organic fertilizer∶microbial agent=80∶1(kg)],the comprehensive performance of flue-cured tobacco was significantly better than that in the control groups,the yield of tobacco leaves reached 2237.1 kg/ha,the output value was 45505.2 yuan/ha,and the average price of the tobacco leaves was 20.53 yuan/kg.The performance of flue-cured tobacco in the treatment of 70%local fertilizer consumption+1500 kg/ha Kunyijian ranked second.The performance of other fertilization treatments was not good,but it did not differ significantly from that of control 1.In terms of chemical composition of tobacco leaves,partial replacement of chemical fertilizer by bio-organic fertilizer Kunyijian,was beneficial to increase the sugar content and reduce the nicotine and total nitrogen contents in tobacco leaves,especially the treatment of 70%local fertilizer consumption+900 kg/ha Kunyijian[organic fertilizer∶microbial agent=80∶1(kg)],and it was also beneficial to increase the chlorine content in tobacco leaves,especially the treatment of 70%local fertilizer consumption+1500 kg/ha Kunyijian[organic fertilizer∶microbial agent=80∶1(kg)].Therefore,it is feasible to use the bio-organic fertilizer Kunyijian to replace 30%of chemical fertilizer in tobacco production.The rate is recommended to be 900-1500 kg/ha[organic fertilizer∶microbial agent=80∶1(kg)].It is suggested to further strengthen the demonstration and promotion of Kunyijian.

Application of Bio-organic Fertilizer Containing High-efficient Nitrogen-fixing Bacillus amyloliquefaciens on Strawberry

With strawberry as a test material,the effects of the bio-organic fertilizer containing high-efficiency nitrogen-fixing Bacillus amyloliquefaciens on nutrient contents in strawberry-planted soil,wilt occurrence and strawberry yield and quality were studied by a plot experiment,so as to provide reference for scientific use of the bio-organic fertilizer and green production of strawberry.The results showed that after hole-applying the bio-organic fertilizer at a rate of 22.5 t/hm^2,the contents of NH^+_4-N,available P,available K and organic matter did not change much with time;and when replacing 50%of chemical fertilizers with the bio-organic fertilizer at a rate of 11.25 t/hm^2(K_3),the contents of NH^+_4-N and available P in the soil did not change much with time,and the contents of available K and organic matter decreased slightly with time,but were both higher than the CK(the unfertilized treatment).Meanwhile,the disease index values of strawberry wilt disease in treatments K_2 and K_3were significantly lower than those of the CK and the conventional fertilization treatment(K_1),and the vitamin C contents of strawberry fruit in the two treatments were significantly higher than that of the CK.The yield determination showed that the cumulative yields of treatments K_2 and K_3 increased by 9.8% and 3.3%,respectively,and the increase rates of the early yields(before the Spring Festival)were 30.6% and 21.9%,respectively.Therefore,the application of the bio-organic fertilizer can replace chemical fertilizers,and can achieve the effects of reducing the occurrence of wilt,improving the early yield of fruit commodity and improving fruit quality.

Through the application of bio-organic fertilizer on Chuanzhuo 16, the re- sults showed that the yield could reach 185.23 kg in treatment with bio-organic fer- tilizer, 40.22 kg more than the conventional fertilization, and the yield increase rate reached up to 27.7%.

Effects of different ration of NPK fertilizer on the grain yield and protein content in forage rice

Different ratios of NPK were adopted in this research to study its effects on the objective traits of 2 early forage-rice varieties, and to obtain the optimum ratio to further improve the application technique in theory. At the same time, the possibility of increasing yield and protein content in the grain through cultivation technique was also studied. The conclusions were：

Co-application of compost or inorganic NPK fertilizer with biochar influences soil quality,grain yield and net income of rice

Most agricultural soils in sub-Saharan Africa are degraded,compromising the grain yield of rice and farmers return on investment.A 3-year field study was undertaken to explore the effect of the application of compost or inorganic NPK fertilizer applied alone or in combination with biochar on soil quality,grain yield of rice and net income.The five treatments were laid out using a randomized complete block design with four replications.The treatments were applied to supply approximately 75 kg N ha–1.The best fertilizer input was compost+biochar which resulted in the greatest improvement in soil physico-chemical properties by reducing bulk density and increasing porosity and moisture retention,organic matter content,percent nitrogen,available phosphorus and cation exchange capacity.Apart from treatment with inorganic fertilizer alone,treated soils showed a decrease in pH.Bacterial and fungal counts and basal respiration decreased in soils in the following order:compost+biochar>compost only>inorganic NPK fertilizer+biochar>inorganic NPK fertilizer>control.The increase in pooled grain yield and net income in response to treatment followed the order:compost+biochar>NPK+biochar>NPK>compost>control.The findings suggest that the use of compost or NPK alone might improve soil quality and increase grain yield and net income,but it is greatly recommended to co-apply these fertilisers with biochar.

Potentials of NPK and Organic Fertilizers on Growth Performance of Cashew （Anacardium occidentale L,） Seedlings on Degraded Typic Alfisol Soils in Ibadan, Nigeria

Sequel to complaints by cashew farmers on poor establishment rate of cashew seedlings on rehabilitated moribund cashew plantations in south western Nigeria, a fertilizer trial involving the use of organic materials （cow-dung, poultry droppings, cocoa and kola pod husks） compared to NPK and control （no fertilizer） treatments was conducted on the growth performance of cashew seedlings at Ibadan, Nigeria. The fertilizers were applied to supply 15 g N seedlingl in 3 replications. Cashew seedling growth parameters and dry matter yield were determined. Fertilizers resulted to consistently general higher plant height, girth, number of leaves and leaf area compared to NPK and control. The differences in the mean values were however not significantly different for girth but it was significant （P 〈 0.5） for plant height, number of leaves and leaf area, while there was no particular regular trend for plant number of branches. Plant root lengths were significantly higher using the organic fertilizers than NPK and control. Similar trend was obtained in the dry weight values for plant leaf, stem, root and total dry matter yield. There was however no consistent significant effect on NPK usage over control for all the parameters. It was therefore deduced that optimal growth performance and better establishment of cashew seedlings could be obtained with the use of organic fertilizers rather than inorganic fertilizer. The use of cocoa pod husk followed by cow-dung and poultry droppings were outstanding in better growth and dry matter yield performance of cashew seedlings and were advised for this purpose.

Growth and Yield of Rice(Oryza sativa L.)Applied by Inorganic and Organic Fertilizer in Indonesian Tidal Soil

The aims of this study were to determine the dose of inorganic fertilizer of NPK combined with organic fertilizer from CM(Cow Manure)to grow paddy Inpara 8 variety planted in a tidal soil.This experiment was done in a green house and conducted from July to December 2020.This pot experiment used factorial completely randomized design with two factors and three replications.The first factor was NPK which consisted of two kinds of NPK fertilizers which were urea 200 kg/ha,SP-36100 kg/ha,KCl 100 kg/ha from recommended fertilization and urea 37 kg/ha,SP-3656 kg/ha,KCl 183 kg/ha from calculation of the specific location soil analysis(in situ data).The second factor was dosage of CM at 5,7.5 and 10 tons/ha respectively.The results showed that NPK fertilization from specific location combined with CM at 10 tons/ha was the best treatment for rice production in an infertile tidal swampland producing 2.20 tons/ha.

A Quadratic Regression Analysis of the Effect of Three Levels of NPK Fertilizer on the Yield of Yellow Maize

Fertilizers are essential to modern agriculture;their overuse can have harmful effects on plants, crops and soil quality. Thus, the study seeks to investigate, if (actually) the trio of Nitrogen, Phosphorus and Potassium (NPK) contribute to the growth and yield of yellow maize, and to determine at what proportion each of the elements is to be applied for optimum yield. Our findings revealed that Nitrogen and Phosphoric fertilizer contributed significantly to the yield of yellow maize while there was no significant effect of Potassium Further analysis on the mean separation of Nitrogen and Phosphorus using Duncan’s Multiple Range Test—(DMRT) showed Nitrogen at 50 kg/ha as significantly higher than the other levels. For phosphorus, its effect at 20 kg/ha was significantly higher than the other levels. Thus, the derived quadratic model: .

Comparative Evaluation of NPK Fertilizer and Tithonia diversifolia Biomass in Sweet Pepper （Capsicum annum） Production in Ado Ekiti, Nigeria

The efficacy of the flower, leaf, stem and root of Tithonia diversifolia as organic fertilizer was comparatively studied with NPK fertilizer in improving the performance of sweet pepper （Capsicum annum） in the green house of the Department of Plant Science of Ekiti State University, Ado Ekiti, Nigeria. The different parts of Tithonia diversifolia were harvested, separately air dried and pulverized. 100 g each of the Tithonia parts and 10 g of NPK were respectively buried into each pot containing the pepper seedlings at two weeks after transplanting using the side dressing method. The study results showed that the leaf biomass of T. diversifolia was not significantly different from NPK fertilizer in improving the growth and yield of Capsicum annum. The stem and root biomass gave comparative growth and yield figures but higher than those recorded from the flower biomass. The control pots resulted to the lowest performance of capsicum annum. It is indicative in this study that Tithonia diversifolia plants ploughed into the soil at the tender stage before flowering will be useful in soil improvement for pepper production. It also revealed that the leave biomass contains nutrients in the required quantity that compared favourably with NPK for pepper production in the study area.

Growth, Yield and Water Use Effeciency of Forage <i>Sorghum</i>as Affected by Npk Fertilizer and Deficit Irrigation

Drought stress (DS) is an important limiting factor for crop growth and production in some regions of the world. Limitation in water availability precludes optimal irrigation in some production regions. Therefore, investigations on the interaction of other factors to mitigate the DS to varying degree are important. Two field experiments were conducted in the experimental farm of the National Research Centre, Shalakan, Kalubia Governorate, Egypt, during 2004 and 2005 summer seasons to evaluate the interactions between N, P, K rates and optimal vs. deficit irrigation regimes on biomass yield as well as water use efficiency (WUE) of forage sorghum. Omission of the 4th irrigation significantly decreased the biomass of sorghum c.v. Pioneer, as compared to that of the plants receiving optimal irrigation or subject to omission of the 2nd irrigation. The biomass yield increased with an increase in NPK fertilizer rates. Plant height and leaf area also decreased by omitting the 2nd irrigation as compared to that of the plants under optimal irrigation, and further declined with omission of the 4th irrigation. The biomass of the plants (dry weight basis) that received the high N, P, K rates was greater by 26%, 29%, and 35% as compared to that of the plants that received no N, P, K fertilizers, under optimal irrigation, omission of the 2nd, and omission of the 4th irrigation, respectively. The corresponding increases in water use efficiency (based on fresh weight yield) were 37%, 42%, and 55%.

Effects of Slow-release Fertilizer and Balanced Fertilization on Nitrogen, Phosphorus and Potassium Uptake in Peppers

Field plot experiment was conducted to study the effects of two slow-re- lease fertilizers and balanced fertilization on dry matter accumulation, yield, fertilizer use efficiency, nitrogen, phosphorus and potassium uptake of peppers at Jiangna Town, Yanshan County, Yunnan Province in 2011. The results showed that the dry matter accumulation in dried pepper plant, pepper yield, nitrogen, phosphorus, potassium uptake in peppers were significantly increased in all the fertilizer treat- ments, compared with those in control （no fertilizer）. Compared with conventional fertilization, balanced fertilization, slow-release compound fertilizer and slow-release urea fertilizer significantly increased dried pepper economic output by 20.94%, 17.5% and 14.54%, nitrogen uptake in dried peppers by 21.53%,18.46% and 13.19%, phosphorus uptake in dried peppers by 14.08%, 15.76% and 10.44%, potassium uptake in dried peppers by 22.66%, 15.73% and 16.28%; they also in- creased nitrogen and potassium use efficiency, but reduced potassium use efficiency due to the increased potassium addition. In treatments with balanced fertilization, slow-release compound fertilizer and slow-release urea fertilizer, the nitrogen utiliza- tion was 5.84%, 7.14% and 8.33% higher and the phosphorus utilization was 3.32%, 3.27% and 2.47% higher than those in treatment with conventional fertiliza- tion. In addition, the nitrogen application could be reduced by 20%-50% by bal- anced fertilization and the two slow-release fertilizers, thereby reducing environmen- tal pollution. Slow-release fertilizers could also reduce the frequency of fertilization and labor costs.

Effects of Full-Element Bio-Organic Fertilizer on Growth,Yield,and Rhizosphere Soil Nutrients of Pepper

A field experiment was conducted to evaluate the effects of self-developed full-element bio-organic fertilizer on the growth,yield,and rhizosphere soil nutrients of pepper.Four treatments were designed,including full-element bio-organic fertilizer+conventional fertilizer reduced by 50%(T1),inactivated full-element bio-organic fertilizer+conventional fertilizer reduced by 50%(T2),conventional fertilizer(T3),and no fertilizer(CK).The results showed that T1 significantly increased the plant height,crown width,fruit number per plant,and yield of pepper.T1 had higher pH value,total nitrogen,total phosphorus,total potassium,available nitrogen,available phosphorus,and available potassium in the rhizosphere soil than T3 and CK,and it had higher available phosphorus and available potassium than T2.The disease index of bacterial wilt in T1 was 21.74,which was 10.37,20.19,and 35.48 lower than T2,T3,and CK,respectively.The control effect of T1 reached 56.71%.The above results indicated that whole bio-organic fertilizer promoted the growth to improve the yield and benefit of pepper.Moreover,the fertilizer activated soil nutrients to improve soil fertility and reduced soil-borne diseases.Therefore,the full-element bio-organic fertilizer can be promoted in the pepper fields with continuous cropping obstacles.

Comparison of the Effect of Vermicompost and Inorganic Fertilizers on Vegetative Growth and Fruit Production of Tomato (<i>Solanum lycopersicum</i>L.)

This study attempted to compare the effect of cow manure vermicompost and inorganic fertilizers on the vegetative growth and fruits of tomato plant (Solanum lycopersicum L.). An air dried sandy loam soil was mixed with five rates of vermicompost equivalent to 0 (control), 5, 10, 15 and 20 t ha-1 and three rates of NPK fertilizer equivalent to 50% (N-P-K = 69-16-35 kg ha-1), 100% (N-P-K = 137-32-70 kg ha-1) and 200% (N-P-K = 274-64-140 kg ha-1). The treatments were replicated three times. The data revealed that shoot length, number of leaves, dry matter weight of shoots and roots, fruit number and fruit weight were influenced significantly (P < 0.05) by the application of vermicompost and NPK fertilizer in the growth media. The highest dose of vermicompost of 20 t ha-1 increased dry weight of shoot of 52 folds and root of 115 folds, number of fruit(s)/plant of 6 folds and mean fruit weight of 29 folds while the highest rate of NPK fertilizer of 200% increased dry weight of shoot of 35 folds and root of 80 folds, number of fruit(s)/plant of 4 folds and mean fruit weight of 18 folds over the control treatment. The growth performance of tomato was better in the vermicompost amended soil pots than the plants grown in the inorganic fertilizer amended soil pots. This study suggested that the vermicompost served as a potential source of nutrients for plant growth.

Phycological Effects of Eutrophication with Fertilizers in Nike Lake, Nigeria

Agriculture around Nike lake uses fertilizers. Fertilizers are known to cause eutrophication of water bodies and associated algal blooms whose consequences may be deleterious to the environment and man. We investigated ex situ to assess the effect of the nutrients on the algal flora and show the impact of farm land runoffs on aquatic environment. The lake water was analysed for initial nitrogen, phosphorus and potassium;and algal content using standard methods. The fertilizer sources used by the farmers—NPK (20:10:10 and 15:15:15);urea and poultry drops, were used in the study to enrich the lake water in concentrations of 0.2, 0.4, 0.6, 1.0 and 2.0 g/L in three replicates respectively. A control was set up without the fertilizer sources and the set up was left on a laboratory bench and monitored for 36 days. Cyanobacteria (blue green algae), Chlorophyta (green algae) and Bacillariophyta (diatoms) were encountered and their population increased with time and increase in concentration of fertilizers. The following taxa were encountered—Gloeocapsa, Anabaena, Oscillatoria (blue-green algae);Chlorella, Chlamydomonas, Spirogyra, Closterium, Pediastrum, Ankistrodesmus, Selenastrum, Scenedesmus, Staurastrum (green algae);Pinnularia and Navicula (diatoms) some of which are notable bloom forming species.

Growth and Yield Response of Soyabean (<i>Glycine max</i>Merr.) to Organic and Inorganic Fertilizer in Edo Rainforest of Nigeria

In tropical and subtropical areas, the importance of organic manure and inorganic fertilizer in increasing crop production for food security cannot be overemphasized. A field study was therefore conducted at the Department of Crop Science, University of Benin Teaching and Research Farm, Benin City, Edo State during the 2012/2013 cropping seasons, to investigate the effects of poultry manure and inorganic NPK 15:15:15 fertilizer on the growth and yield of soya bean (Glycine max (L.) Merr). The experiment was laid out as a randomized complete block design (RCBD) in three replications with six treatments viz: 0, 200 kg/ha NPK 15:15:15, 10 t/ha poultry manure, 7 t/ha poultry manure + 60 kg/ha NPK 15:15:15, 5 t/ha poultry manure + 100 kg/ha NPK 15:15:15, 2.5 t/ha poultry manure + 150 kg/ha NPK 15:15:15. Parameters on vegetative and reproductive traits were taken on five randomly selected plants. Results showed that plant height, number of branches and number of leaves per plant were enhanced by organic and inorganic fertilizers. Similarly, combined application of organic and inorganic fertilizer increased the pod weight/plant compared to the sole application of organic and inorganic fertilizer. Application rate of 2.5 t/ha poultry manure + 150 kg/ha NPK 15:15:15 gave the highest grain yield of 7.367 t/ha followed by 5 t/ha poultry manure + 100 kg/ha NPK which gave (7.244 t/ha), application rate of 7 t/ha poultry manure + 60 kg/ha NPK gave (6.654 t/ha), while 10 t/ha poultry manure gave (3.889 t/ha) and this was followed by application rate of 200 kg/ha NPK 15:15:15 which gave (4.112 t/ha) and the control gave the lowest grain yield of (3.245 t/ha). The application of 2.5 t/ha poultry manure + 150 kg/ha NPK 15:15:15 is therefore suggested for the growth and yield of soyabean in Edo rainforest of Nigeria.

Integrated Effects of Rhizobial Inoculum and Inorganic Fertilizers on Wheat Yield and Yield Components

An experiment was conducted in pots under natural condition with two factor factorial completely randomized design (CRD) (CRD) to investigate the integrated effect of rhizobia inoculums and inorganic fertilizers on growth and yield of wheat crop at The University of Agriculture Peshawar, during 2012-2013. The experiment was comprised of four inoculums (no, lentil, peas and chickpeas) and two NPK levels (recommended 120:90:60 kg·ha-1 & 20% less of recommended). It was observed that inoculation of wheat by rhizobia significantly increased tillers per plant by a maximum of 42%, plant height by 13%, grain per spike by 16%, 100 grain weight by 10%, biological and grain yield by 10% over un-inoculated (control) treatment. Among inoculums, peas inoculum was found to be the most efficient for all traits except plant height where chickpea inoculum performed better. Similarly recommended NPK significantly increased tillers per plant by 33%, plant height by 19%, grain per spike by 9%, 100 grain weight by 10%, biological yield by 8% and grain yield by 10% compared with 20% less of recommended NPK. Interactive effect of inoculum x NPK was significant for tillers per plant, grain per spike, grain yield and non-significant for plant height, 100 grain weight and biological yield. However, it was evident from the results that inoculation improved all traits both under recommended and 20% less of recommended NPK. The persistent good performance of peas and lentil rhizobial inoculation in wheat growth exhibited that this could be used as a plant growth promoting rhizobacteria for wheat and other cereal crops in prevailing soil and climatic conditions.
