Abstract:

The field experiment was conducted during the kharif season of 2015 at Teaching Farm, Mondouri in New Alluvial Zone (NAZ) under Bidhan Chandra Krishi Viswavidyalaya, Nadia to study the ‘Effect of differential nutrient levels on the performance of paddy hybrid variety during kharif season’. The experiment was laid out in split plot design with six treatment combinations consisting of two cultivars, three levels of fertility in three replicates. The cultivars were PAC 8744 (hybrid) and IET 4786 (HYV) tested with different levels of NPK nutrient supply as 60 : 30 : 30, 80 : 40 : 40, 100: 50 : 50 kg N, P2O5 and K2O ha-1 with a plant spacing of 20 cm × 15 cm. The results revealed that hybrid rice variety PAC 8744 performed well as compared to high yielding variety IET 4786 in respect of different crop growth and yield attributes. The varietal effect was significantly noted in crop growth in terms of plant height, tillering and dry matter production at 60 DAT and at harvest. Among the yield components, the effective tillers per square meter, number of filled grains per panicle, numbers of chaffy grains per panicle and test weight were significantly influenced by the variety and nutrient management. In hybrid PAC 8744, number of panicle per m2 was 472 which were 41.3% more than IET 4786. The highest tiller production was noted in F3-100:50:50 kg N, P2O5 and K2O ha-1. Both grain and straw yield were significantly influenced by variety and nutrient level. The highest grain and straw yield of 6.05 and 9.18 t ha-1 were found in PAC 8744 with NPK nutrient level of @100:50:50 kg ha-1 respectively. The yield advantage of PAC 8744 was 78.61% higher over IET 4786 during kharif season of 2015. In a similar way, the experimental result revealed that the hybrid variety PAC 8744 showed higher benefit-cost ratio of 2.17 with maximum response to the highest level of nutrient management of N, P2O5 and K2O @100:50:50 kg ha-1. It was, therefore, advantageous to grow hybrid rice cultivar PAC 8744 with the fertilizer dose of 100:50: 50 kg N, P2O5, K2O ha-1 during kharif season so as to obtain higher grain yield over the best check IET 4786.
