A field experiment was conducted during kharif (rainy) and subsequent rabi season of 2014-15 and 2015-16 at the District Seed Farm, AB block, Kalyani, Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India to identify the ideal lentil varieties and standardize the fertilizer combination to get optimum yield for relay cropping with long duration (MTU 7029) rice in new alluvial zone of West Bengal. The experiment was laid down in split plot design with three replications taking three varieties (V1: PL 6, V2: Moitri and V3: Subrata) placed in the main plot and four fertilizer levels (F1: 20 kg N, 40 kg P2O5 and 40 kg K2O ha-1 at basal, F2: 2% Urea foliar spray at 45 DAS and 65 DAS, F3: 20 kg N, 40 kg P2O5 and 40 kg K2O ha-1 at basal + 2% Urea foliar spray at 45 DAS and 65 DAS, F4: Control plot) was in the sub-plot. Results of two years of the experiment revealed that all the three varieties performed better as well as the yield attributing characters were recorded highest with F3 fertilizer level (20 kg N, 40 kg P2O5, 40 K2O and 2% Urea foliar spray at 45 DAS and 65 DAS). Maximum dry matter accumulation (339.84 gm-2) was observed in PL 6 with F3 fertilizer level at maturity stage. Highest numbers of branches (15) were found in Moitri and number of pod per plant (81) was highest in Subrata followed by V2F2 treatment combination. Highest yield (1355.5 kg ha-1) was recorded in Moitri followed by Subrata (1310.1 kg ha-1) irrespective of fertilizer levels but Subrata and Moitri were statistically at par. V2F3 treatment combination attained highest yield (1603.8 kg ha-1). Thus it could be concluded that farmers of New Alluvial Zone of West Bengal can adopt Moitri or Subrata cultivars of lentil as relay crop with application of 20 kg N, 40 kg P2O5 and 40 kg K2O ha-1 at basal along with 2% Urea foliar spray at 45 DAS and 65 DAS.
