Abstract:
To study the direct and residual effect of integrated sources of nitrogen on the growth productivity and economics of rice (aromatic)-lentil cropping system investigation was conducted at the instructional farm of Uttar Banga Krishi Viswavidyalaya located at Pundibari, Cooch Behar, West Bengal during 2016-17 and 2018-19. The experiment was laid out in split plot design with 2 aromatic rice varieties (Gobindabhog’ and ‘Kalonunia’) in main plots and 12 treatments of nitrogen management in sub-plot. The results of the experiment showed that the variety ‘Gobindabhog’ (main plot) recorded higher growth, yield attribute, yield and quality (Carbohydrate, protein content, aroma, hulling percentage, milling percentage and Head rice recovery) as compared to Kalonunia. For the sub-plot, the treatment 50% RDN through fertilizer + 50% RDN through VC recorded to give maximum growth, yield attribute, yield and protein content. Application of 50% RDN through VC + 50% RDN through FYM brought about positive response on the hulling (%), milling (%) and head rice recovery (%) and aroma. The highest rice carbohydrate content was found with 50% RDN through fertilizer + 25% RDN through VC + 25% N through FYM treatment. The maximum grain yield of residual effect of succeeding lentil crop was observed in plots of Gobindabhog and 50% RDN through fertilizer + 50% RDN through FYM treated plots. The highest gross and net returns were obtained with the application of 75% RDN through fertilizer + 25% RDN through VC in the plots, where the crop was ‘Gobindabhog’ rice and the benefit: cost ratio was also higher in the same set of treatment.
