Abstract:
A field experiment was conducted for three kharif seasons (2014, 2015 & 2016) at Regional Agricultural Research Station, Nandyal, Andhra Pradesh to study the ill effects of waterlogging stress conditions on yield attributes, seed yield, benefit cost ratio and available soil nutrient status of three crops viz, Cotton, Maize and Sunflower. Higher yields of maize, sunflower and cotton crops under ridge and furrow method with nutritional management practices recorded 4260, 652 and 835 kg/ha respectively. The study indicated that along with planting methods like Broad bed furrow (BBF), Ridge & Furrow methods (R&F) along with nutrient management practices like Urea Application of @ 50 Kg/ha along with spraying of liquid fertilizers like Multi K (13-0-45) & Urea solution @ 2% and Gypsum application @ 500kg/ha at critical stages of crop will lead you for crop sustainability and maintaining the available N, P and K of soil, leading to positive nutrient balance. Measures to ameliorate the ill effects of waterlogging stress conditions will lead to enhancement of productivity of rainfed crops besides relieving distress among farmers when high rainfall situations occur.
