Yield and Nutrient Uptake of Winter Groundnut (Arachis hypogaea L.) Under Integrated Input Management and Polythene Mulch in the Konkan Region of MS

摘要

The field experiment was conducted at Agronomy Department Farm, College of Agriculture, Dapoli, MS on die lateritic soil to study the role of different components of production technology of groundnut (Arachis hypogaea L.) under polythene mulch. The factors considered were viz, improved varieties, seed bed's, nutrition levels and plant. growth regulator. Results revealed that the groundnut genotypes TG 26 and JL 24 recorded 51 q ha(-1) and 53 q ha(-1) dry pod yields respectively. JL 24 recorded significantly higher total mean nitrogen, phosphorus, potassium and calcium uptake over TG 26. The dry pods, kernels, oil, haulm yield and nutrient uptake were considerably higher due to application of 50: 100: 70 kg N, P2O5 and Ca/ha and 75 : 150: 105 kg N, P2O5, and Ca/ha than the other treatments under study. Polythene mulched rabi groundnut gave equal pod, haulm yield, nutrient uptake oil both the seed beds viz., flat bed and broad bed furrow (BBF). The dry pod, kernel and oil yield was increased significantly due to application of paclobutrazol.
