An one year field experiment was carried out in Instructional Farm, Bidhan Chandra Krishi Viswavidyalaya, Mondouri, Nadia, West Bengal, India during rabi season of 2017 to find out the yield and yield attributes of different irrigation and nutrient management of var. Pusa Bold. The experimentation was laid out in split plot design with irrigation in the main plot and fertiliser doses in subplots. At harvest, irrigation levels significantly influenced plant height. Three post-sowing irrigations viz. one irrigation at 30 DAS (I1), one irrigation at 60 DAS (I2) and two irrigations at 30 and 60 DAS (I3), three nutrient treatments viz. No fertiliser or manure (F0), 100% recommended NPK i.e. 80kg N, 40 kg P and 40 kg K ha-1 (F1) and 100% recommended NPK plus fresh cow dung slurry (FCS) @10,000 lit ha-1 (F2) were tested in a split plot design. Biomass production was significantly greater in I3 than I1 and I2, and in F2 than F1 and F0. The I3 x F2, I1 x F2 and I3 x F1 combinations maintained significantly greater plant height and yield components. Number of siliqua per plant and seeds per siliqua were the major contributors to the seed yield. The crop yield was the highest in I3XF2 combinations, and the similar yield was obtained in I1XF2 and I3XF1 combinations. Application of organic manure in the form of fresh cow dung slurry (FCS) with 100% NPK fertilisers produced greater plant height, crop growth rate, biomass production and yield attributes and saved one post sowing irrigation. Increasing dry matter accumulation with nutrient management was observed over control at this stage. F2 (Full dose of NPK + FCS) gave the best result which was statically at par with F1 (Full dose of NPK).Interaction effect was found to be significant at this stage i.e. I3 × F2 was found with best result. The lowest value was recorded with I2 × F0.
