Viral diseases in crop plants constitute a major obstacle to food security in the developing world. Subsistence crops, including cassava, sweetpotato, potato, banana, papaya, common bean, rice and maize are often infected with RNA and/or DNA viruses that cannot be controlled with pesticides. Hence, healthy planting materials and virus-resistant cultivars are essential for high yields of good qu...
Rainfall is important for food production plan, water resource management and all activity, plans in the nature. The occurrence of prolonged dry period or heavy rain at the critical stages of the crop growth and development may lead to significant reduce crop yield. Indian is an agricultural country and its economy is largely based upon crop productivity. Thus rainfall prediction becomes a sign...
Cereal crops form the bulk of the world's food sources, and thus their importance cannot be understated. Crop breeding programs increasingly rely on high-resolution molecular genetic markers to accelerate the breeding process. The development of these markers is hampered by the complexity of some of the major cereal crop genomes, as well as the time and cost required. In this review, we address...

Corn was an important crop for people who lived in the area that became Illinois before the Europeans first set foot here; it was the staple food crop of the people who lived in the Cahokia area some 1,000 years ago. It was a crop of choice when Europeans settled and started to farm in Illinois, and acreage in the state first reached 10 million acres in 1895. Acreage over the past 100 years has...
the study carried out an assessment of agricultural land management practices in food crops production among small scale farmers in kwara sate, nigeria. specifically, the study determined the socio economic characteristics of crop farmers in kwara state; ascertained the cropping patterns common among them; highlighted the soil conservation methods adopted by the farmers; examined the relationsh...
The concept of "Plant factory" could realize the multiple targets of high yield, high quality, high efficiency and security. It had become the trend of agricultural development. It solved the growing contradiction between people's increasing demand for green, organic food and the diminishing agricultural arable area in China. According to the research on the key technologies of plant factory, a...
The complexity of risks posed by climate change and possible adaptations for crop production has called for integrated assessment and modelling (IAM) approaches linking biophysical and economic models. This paper attempts to provide an overview of the present state of crop modelling to assess climate change risks to food production and to which extent crop models comply with IAM demands. Consid...
Traditional farming practices suggest that cultivation of a mixture of crop species in the same field through temporal and spatial management may be advantageous in boosting yields and preventing disease, but evidence from large-scale field testing is limited. Increasing crop diversity through intercropping addresses the problem of increasing land utilization and crop productivity. In collabora...
