A field experiment was conducted at Agricultural Research Station, Kota during the Rabi seasons2019-20 to find out suitable nutrient management levels of nitrogen, phosphorous and potassium in irrigated condition of south- eastern Rajasthan. The treatments comprised three levels of nitrogen (80, 100 and 120 kg/ha), two levels of phosphorous (40 and 50 kg/ha) in main plot and three levels of potassium fertilizer (15, 30 and 45 kg/ha) in sub plot were laid out in split-plot design with 3 replication. Application of 120 kg N/ha had significance effect at harvest, over 80 kg N/ha, on plant height (224.5 cm), dry matter/meter row length(346.8 g), primary and secondary branches/plant (5.82 and 15.02), siliquae/plant (213.8), seeds/siliqua (15.94), length of siliqua (5.53 cm), 1000-seed weight (5.30 g), seed yield (2861 kg/ha) and stover yield (7016 kg/ha)however, 120 kg N/ha was remained on par with 100 kg N/ha. The application of 50 kg P2O5 had significant effect on dry matter accumulation per meter row length (329.64 g), height at 60 and 90 DAS (91.6 and 191.1 cm) primary and secondary branches/plant (5.45 and 14.66) siliquae/plant (204.3), seeds/siliqua (15.94), length of siliqua (5.43 cm), 1000-seed weight (5.19 g), seed yield (2830 kg/ha) and stover yield (6929 kg/ha).The application of 45 kg K2O/ha was had significant effect as compared to 15 kg K2O/ha, on plant height (210.5 cm) dry matter accumulation per meter row length (334.2 g), primary branches/plant (5.46),siliquae/plant (203.2), seeds/siliqua (16.03), length of siliqua (5.46 cm), 1000-seed weight (5.17 g) seed yield (2856 kg/ha) and stover yield (7050 kg/ha). However 45 kg K2O/ha was found on par with 30 kg K2O/ha. The application of 100 kg N with 50 kg P2O5 and 30 kg K2O/ha was found beneficial for obtaining high seed yield in irrigated conditionsof south- eastern Rajasthan.
