The success of the Green Revolution in closing the gap between world population and food production was principally achieved by increasing crop productivity in favorable areas. However, this success has been limited in the rainfed systems, which are prone to frequent droughts and other abiotic stresses. Worldwide, drought affects approximately 23 million hectares of rainfed rice. Varieties comb...

Climate change represents the major challenge to Sudan agricultural production, economics and food security. Changes in temperature, rainfalls, water availability, increased outbreak of pest and diseases, land degradation, soil erosion, shrinking of grazing and cultivate areas, ongoing desertification and the other aspects of climate change have direct significant impact on agricultural product...

Background: Cotton with coevolving pests has been grown in India more than 5000 years. Hybrid cotton was introduced in the 1970s with increases in fertilizer and in insecticide use against pink bollworm that caused outbreaks of bollworm. Hybrid Bt cotton, introduced in 2002 to control bollworm and other lepidopteran pests, is grown on more than 90 % of the cotton area. Despite initial declines,...

Safflower [Carthamus tinctorius (L.)] is a multipurpose oilseed crop grown mainly for getting high quality edible oil rich in polyunsaturated fatty acids. India is the largest producer of safflower in the world with 402,000 hectares area under it, producing about 206,000 tons of safflower seed annually [1]. But its use in India is limited mainly to oil extraction from seed and leftover cake as ...

Global food security requires eco-efficient agriculture to produce the required food and fiber products concomitant with ecologically efficient use of resources. This eco-efficiency concept is used to diagnose the state of agricultural production in China (irrigated wheat-maize double-cropping systems), Zimbabwe (rainfed maize systems), and Australia (rainfed wheat systems). More than 3,000 sur...
