It is observed contamination and subsequent growth of various types of mycotoxins in the production and processing of grain and non-grain crops. The contamination of grain and non-grain cereals crops harvest was analyzed. The aim of this research is using of microwave energy to disinfect grains of harvest and giving new properties to the grains and plants materials. The author has presented researches of the grains disinfection, during seedbed preparation and post processing. Rational parameters of heating rates of different biological objects were identified, revealed their dependence and impact on infection pathogens, through using of microwave energy technology. The author found a reduction of the number of pathogenic microbes and organisms at the various stages of processing agricultural products during using of microwave energy, and found new qualitative indicators of the products properties. 展开更多

Outgrower Schemes have been implemented in different parts of the world to provide wood to forest and other companies and as income alternatives for farmers in rural areas. They have been considered by some researchers and practitioners as important advances in the area of planted forest and promoted by governments and forest companies in partnership with rural farmers and communities. Considering the importance of subsistence crops and forest products to smallholders and consumers and the economic viability of agroforestry, attention is given in this paper to Outgrower Schemes that combine tree planting with agroforestry, to contribute to food security and environment preservation in developing countries. The issue of Outgrower Schemes through integrated crops-tree systems was raised in a previous study of Outgrower Schemes in Brazil, commissioned by the FAO1. This paper examines, based on the research done for that study, the views and perspectives of the companies' personnel, the tree growers that participate in the programs studied, and other stakeholders' related institutions involved in such schemes with regard to the promotion of Outgrower Schemes through integrated crops-tree systems, linking them with agroforestry, which is a way those Outgrower Schemes can contribute to food security and environment preservation goals. 展开更多

Sorghum bicolor is among main staple crops of Chad but it is commonly attacked by Striga hermonthica. Assessment of sorghum varieties for resistance to this weed was carried out during three cropping seasons (2005-2008), in controlled conditions; promising entries (those which fulfilled at least 75% of selection criteria) were evaluated in farmer field in 2008-2009 seasons. There were five sites (Bebedjia, Deli, Bekao, Koudoti and Ndaba). The objective was to evaluate some sorghum entries for S. hermonthica resistance in farmer field. Sorghum test was composed of four entries in Fisher blocks as experimental designs, with five replications. Among different observed variables, there were striga plant count and weight of sorghum grains. One promising entry was selected at Bebedjia and Ndaba (53), two at Deli and Koudoti (50 and 53). No entry was selected at Bekao. Promising entries for the whole Southern zone of Chad were composed of 50 and 53. The best entry was 53 because it was promising in all sites except Bekao. 展开更多

Over 30% rural families in India live in poverty due to small holdings and low soil productivity. As many underutilised tree species are tolerant to harsh agro-climatic conditions, BAIF promoted agri-horti-forestry on degraded lands inhabited by tribals. Traditionally dependent on non-timber forest products, they selected tamarind (Tamarindus indica), jackfruit (Artocarpus heterophyllus), Indian gooseberry (Emblica officinalis) and ber (Zizyphus mauritiana), apart from mango and cashew for their livelihood. Oilseed trees like neem (Azadirachta indica), mahua (Madhuca indica) and jatropha (Jatropha curcas) were introduced on field borders, while the interspace was utilised for cultivating food crops. To ensure higher yield and superior quality of the produce, selection of elite germplasm, domestication through standardisation of cultivation practices and facilitation for supply of planting material are essential, apart from increasing the demand by exploring their uses, creating awareness among consumers and establishing a good distribution network, Intercrops like foodgrains, vegetables and medicinal herbs generated additional income and reduced risk in case of failure of underutilised crops. Introduction of underutilised crops on a small scale with local crops and expansion of their cultivation with the demand is recommended. 展开更多

The Pearl River Delta on China's coast is a region that is seriously threatened by sea level rise and storm surges induced by global climate change, which causes flooding of large areas of farmland and huge agricultural losses. Based on relevant research and experience, a loss evaluation model of farmland yield caused by sea level rise and storm surges was established. In this model, the area of submerged farmland, area of crops, and per unit yield of every type of crop were considered, but the impact of wind, flooding time, changes in land use and plant structure were not considered for long-term prediction. Taking the Pearl River Delta region in Guangdong as the study area, we estimated and analyzed the spatial distribution and loss of farmlands for different scenarios in the years 2030, 2050, and 2100, using a digital elevation model, land-use data, local crop structure, rotation patterns, and yield loss ratios for different submerged heights obtained from field survey and questionnaires. The results show that the proportion of submerged farmlands and losses of agricultural production in the Pearl River Delta region will increase gradually from 2030 to 2100. Yangjiang, Foshan, and Dongguan show obvious increases in submerged farmlands, while Guangzhou and Zhuhai show slow increases. In agricultural losses, vegetables would sustain the largest loss of production, followed by rice and peanuts. The greatest loss of rice crops would occur in Jiangmen, and the loss of vegetable crops would be high in Shanwei and Jiangmen. Although losses of peanut crops are generally lower, Jiangmen, Guangzhou, and Shanwei would experience relatively high losses. Finally, some measures to defend against storm surges are suggested, such as building sea walls and gates in Jiangmen, Huizhou, and Shanwei, enforcing ecological protection to reduce destruction from storm surges, and strengthening disaster warning systems. 展开更多
