Abstract:
One field experiment was conducted at Central Research Farm, Gayeshpur, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during rabi season of 2015-16 and 2016-17 to evaluate the effect of integrated nutrient management on various growth attributes of oat and lathyrus under different cereal-legume based cropping system. The experiment was placed in split plot design with 3 replications comprising 4 levels of cropping system (CS₁-Sole oat, CS₂-Sole lathyrus, CS₃ - Intercropping of oat with lathyrus in 3:2 row ratio and CS₄ -Intercropping of oat with lathyrus in 3:3 row ratio) in the main plot and 4 levels of nutrient management (N₁ - Full RDF through inorganic source, N₂ - 75% N through urea + rest N through FYM, N₃ - 75% N through urea + rest N through vermicompost and N₄ -75% N through urea + rest N through mustard oilcake) in the sub plot. Results revealed that maximum vegetative growths in terms of plant height (99.4 cm and 57.8 cm), leaf area index (4.20 and 1.94), root length (11.6cm and 15.5 cm) and weight (7.42 g and 0.409 g) were recorded for both oat and lathyrus respectively, during 1^st and 2^nd year of experimentation (pooled value of 2 years) when 75% N through urea + rest N through vermicompost was applied. Oat performed better under 3:3 intercropping system due to the advantage of biological nitrogen fixation while, sole lathyrus showed highest performance compared to their other cropping situations.
