Abstract: A field experiment was conducted at Agricultural Research Farm, Banaras Hindu University, Varanasi, Uttar Pradesh during kharif season, 2015 to evaluate the effect of different NPK levels and bio-fertilizers on yield attributes, yield, nutrient content and removal by basmati rice cv. HUBR 10-9. Factorial experiment was laid out in randomized complete block design involving two factors i.e. four NPK levels (control, 50% RDF, 75% RDF and 100% RDF) and three bio-fertilizer levels (BGA, PSB and BGA + PSB), replicated three times. Results revealed that increasing NPK levels up to 100% RDF (120-60-60 kg ha-1) significantly improved yield attributes, grain yield and straw yield as well as nutrient content and removal by grain and straw. Combined application of BGA + PSB proved significantly superior to both BGA and PSB in respect of grain yield, straw yield, NPK content and removal. However, sole application of either BGA or PSB produced comparable results regarding yield attributes and yield. Integration of 100% RDF along with BGA + PSB performed best in achieving higher productivity. Hence, the study suggests that higher fertilizer dose when integrated with bio-fertilizers resulted in better performance of the crop.
