A field experiment was conducted to study the effect of different nutrient management practices for pigeonpea (Cajanus cajan L.) cultivars at Agronomy Main Research Station, OUAT, Bhubaneswar during rabi 2018-2019. The experiment was laid out in Factorial randomized block design with twelve treatment combinations being replicated thrice. Four nutrient management practices viz. F1-STBFR, F2-75% STBFR+FYM (5 t ha-1), F3 - F2 + lime (0.2 LR), F4- F3 + sulphur (20 kg ha-1) were applied to three different pigeonpea cultivars (BRG-4, BRG-5 and Laxmi (ICPL-85063). The nutrient management practice of 75% STBFR+ FYM (5t ha-1) + lime (0.2LR) + sulphur (20 kg ha-1) recorded maximum number of pods plant-1 (44.58), total number of seeds pod-1 (3.84), seed index (12.65 g), seed yield (2061.33 kg ha-1) and stalk yield (5763.33 kg ha-1) and Among the cultivars, Laxmi recorded maximum number of pods plant-1 (43.90), total number of seeds pod-1 (4.03) and seed index (12.11 g) resulting maximum seed yield (2111.17 kg ha-1), stalk yield (5639.67 kg ha-1) and highest harvest index (27.23%).Higher values of total nutrient uptake viz. nitrogen (177.03 kg ha-1), phosphorus(13.82 kg ha-1), potassium(57.47 kg ha-1) and sulphur (4.53kg ha-1) were estimated in cultivar Laxmi and application of 75% STBFR+ FYM (5t ha-1) + lime (0.2LR) + sulphur (20 kg ha-1) recorded the highest total N uptake of 183.38 kg ha-1, total P uptake of 16.16 kg ha-1, total K uptake 58.22 kg ha-1 and total S uptake of 4.79 kg ha-1 resulting a total NPKS uptake of 262.55 kg ha-1.The highest net return (73,856 Rs.ha-1) and B:C ratio (2.55) were recorded at nutrient level of 75% STBFR+ FYM (5t ha-1) + lime(0.2LR) + sulphur (20kg ha-1). Maximum net return (Rs.80,680 Rs.ha-1) and benefit cost ratio (2.84) was recorded in cultivar Laxmi, which was significantly higher than other cultivars .
