Effects of nitrogen (0 to 30 kg/ha) and phosphorus (0 to 60 kg/ha) and its uptake by the crop were studied in two green gram varieties [Rajendran and Pusa Baisaki moono]. Nitrogen levels individually had no influence on seed yield while phosphorus levels showed significant influence. Variety, nitrogen interaction on seed yield was observed. N, P and K per cent in plant dry matter were maximum at pre-bloom stage and decreased thereafter. varieties showed marked difference in nutrient [N, P and K] uptake. Pusa Baisakhi moong removed lesser N. P and K but gave higher seed yield. Crop re- moval of phosphorus ranged between 5 and 10 kg/ha.
