Abstract:
The experiment was conducted in the research farm of Indian Institute of Rice Research (IIRR) Rajendranagar, Hyderabad (Telangana) during kharif season of 2014. The treatments were consisted of two rice cultivars viz. IR-64 and PAC-837 in main plots and four nutrient management viz. 75 per cent RDF, 75 per cent RDF + Biofertilizers (Azospirillum, PSB, VAM @ 5 kg ha^-1), 100 per cent RDF, 100 per cent RDF + Biofertilizers (Azospirillum, PSB, VAM @ 5 kg ha^-1) in sub plots. The recommended fertilizer schedule adopted was 120:60:60 kg N, P₂O₅, K₂O ha^-1 through urea, single super phosphate and muriate of potash. The experiment was laid out in split plot design replicated thrice. The results revealed that PAC-837 obtained significantly higher yield attributes viz number of panicles m^-2, panicle weight (g) and grain yield as compared to IR-64. As regards to nutrient management, application of 100 per cent RDF + Biofertilizers recorded higher yield, nutrient content and uptake.
