How soil moisture conservation practices should be followed in rainfed groundnut crop?

soil moisture

Apply 12.5 tonnes of groundnut shells per hectare at 15-20 DAS as mulch to reduce evaporation losses of soil moisture. To reduce transpiration losses from crop canopy, spray calcium sulphate solution (50 g/l). Spray urea solution (20 g/l) during dry spell period in order to make recover the crop from stress.
