Evaluation of the rice hybrids grown under different INM practices for primary nutrients content and yield under lateritic soil of South Konkan

An attempt has been made to study the response of rice hybrids viz., Sahyadri-3 and Sahyadri-4 to integrated nutrient management comprising different combinations of chemical fertilizers with FYM, poultry manure, glyricidia (green manure) and Biofertilizers (Azospirillum and PSB) in lateritic soils of South Konkan during Kharif, It was revealed from the study that the performance of Sahyadri-3 and Sahyadri-4 hybrid rice in terms of their yield attributes, grain yield productivity, quality traits and economics (gross returns, net returns, B:C ratio) were highest under the application of 50 per cent recommended dose of N through chemical fertilizers, 25 per cent through application of FYM and remaining 25 per cent through poultry manure application. However, in general its effects were statistically at par with those of integrated nutrient management treatments. The said effects due to above treatments were superior over to those of alone application of 100% N applied through inorganic fertilizers to both the rice hybrids.
