Abstract: The experiment was carried out at the Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal during the year 2013-14 and 2014-15. The variety ‘Hissar Sonali’ was taken under the study. Three levels of each nitrogen (40, 60 and 80 kg ha-1), phosphorus (60, 80 and 100 kg ha-1) and two levels of potassium (20 and 40 kg ha-1) were included in the investigation. There were altogether 18 treatments. The experiment was laid out in factorial randomized block design with three replications. Among different treatment combination maximum plant height was observed with N60P100K40 (108.17 cm) at 105 DAS. Plants grown under N60P80K40 combination, exhibited maximum number of primary branch (8.72) per plant. The minimum days required for 50 per cent pod formation was noticed in N40P60K40 (68.12 days). The yield attributing parameters like maximum number of pods plant-1 (76.48) and seed yield plant-1 (14.36 g) were observed in N60P80K40 combination. Maximum projected yield (17.20 q ha-1) was recorded in N60P80K40 followed by N40P80K40 (16.31 q ha-1) and N60P100K40 (15.80 q ha-1) as compared to lowest yield of 11.70 q ha-1 under N40P60K20 combination. In majority of parameters, the increasing trend was noticed with medium level of nitrogen (N60) and phosphorus (P80) but positive response was observed with higher level of potassium. From yield maximization point of view, the most effective treatment was NPK @ 60:80:40 kg ha- 1 followed by NPK @ 40:80:40 kg ha-1 and NPK @ 60:100:40 kg ha-1 under alluvial plains of West Bengal.
