Abstract
A field experiment was conducted during two consecutive years of kharif 2006 and 2007 at Students' Instructional Farm of the University to see the effect of integrated use of different sources of nutrient on yields, nutrient content and nutrient uptake in hybrid rice. Data vividly showed that all the yield attributing characters of hybrid rice were significantly increased with the use of 100% SSNM+5 t FYM+BGA+Azatobacter than inorganic fertilizer application. Use of 100% SSNM+5 t FYM+blue green algae+Azatobacter produced significantly highest grain (80.9 q/ha) and straw (90.8 q/ha) yield of hybrid rice as compared to other treatments. Maximum nutrient contents (N, P and K) were observed in grain and straw of hybrid rice with the application of 100% SSNM+5 t FYM+BGA+Azotobacter over 100% RDF and farmers' practice. Significantly highest total (grain and straw) nutrient uptake of N, P and K (152.9, 35.4 and 169.5 kg/ ha, respectively) in hybrid rice was recorded with the application of 100% SSNM+5 t FYM+BGA+Azatobacter as compared to other treatments. Farmers' practice of nutrient management recorded minimum yield attributes, yield, nutrient content (%) and nutrient uptake (kg/ha) in hybrid rice.
