A field experiment was conducted during the rabi seasons of 2012-13 and 2013-14 to study the influence of sowing window, nutrient dose and foliar spray on yield and nutrient uptake of pigeonpea on sandy loam soil which was low in available nitrogen, medium in available phosphorus and available potassium. The experiment was conducted in a split-split plot design, consisting of three sowing windows in main plots, three nutrient doses in sub-plots and two foliar sprays in sub-sub plots. Crop sown during II FN of September produced significantly higher seed and stalk yield, nutrient content and uptake. Application of 30-60-20 kg N, P2O5 and K2O ha-1 improved seed yield, stalk yield, nutrient content and uptake of redgram. Higher seed yield, stalk yield and nutrient uptake by the crop was recorded with foliar application of NAA (25 ppm) and DAP (2 per cent) applied at 60 and 80 DAS. Interaction between sowing window and nutrient doses, sowing window and foliar sprays were significant in influencing yield of pigeonpea.
