The experiment was carried out with the aim to standardize the dose of NPK of fenugreek cv. Hissar Sonali in gangetic alluvial zone of West Bengal. The experiment was carried out at the Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India during the year 2013-14 and 2014-15. The variety ‘Hissar Sonali’ was used under the study. Three levels of each nitrogen (40, 60 and 80 kg/ha), phosphorus (60, 80 and 100 kg/ha) and two levels of potassium (20 and 40 kg/ha) were included in this 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 of 75.74 cm at 75 DAS were recorded with N₈₀P₈₀K₄₀. Plants grown under N₆₀P₈₀K₄₀combination, exhibited the maximum number of secondary branches (15.94) per plant. The minimum days required for 50% flowering was noticed in N₄₀P₆₀K₂₀ (49.36 days) and test weight (15.24 g) was observed in N₆₀P₈₀K₄₀ combination. Maximum projected yield (17.20 q/ha) was recorded in N₆₀P₈₀K₄₀ followed by N₄₀P₈₀K₄₀ (16.31 q/ha) and N₆₀P₁₀₀K₄₀ (15.80 q/ha) as compared to lowest yield of 11.70 q/ha under N₄₀P₆₀K₂₀ combination. From yield maximization point of view, the most effective treatment was NPK @ 60:80:40 kg/ha followed by NPK @ 40:80:40 kg/ha and NPK @ 60:100:40 kg/ha under alluvial plains of West Bengal.
