ABSTRACT The current cotton (Gossypium hirsutum L.) fallow farming system causes soil degeneration and cotton yield reduction. Cover cropping is commonly associated with improved soil fertility and crop productivity, while the effect of cover crops on soil quality and cotton productivity remains unclear in the region. Using a monoculture cotton (cotton-fallow) as the control, a field experiment was

Abstract Drought stress is one of the major yield limiting factors in grain legumes. The severity and intensity of drought stress are predicted to increase in the future. Drought stress in grain legumes at any stage causes significant yield reduction owing to a decrease in stand establishment (misfunctioning of germination enzymes like proteases and amylases), and nutrient uptake (decreasing water
