Abstract
A field experiment was conducted at Agronomy Research Farm, Narendra Deva University of Agriculture and Technology, Faizabad (U.P.) during kharif season of 2010. The experiment was laid out in split plot design with three replications. The treatments comprised of 3 irrigation schedules (7 cm irrigation 1, 4 and 7 days after disappearance of ponded water in main-plot and 5 nutrient managements i.e. 90+45+45 kg NPK ha−1, 60+30+30 kg NPK ha1+ 30 kg N (through FYM), 60+30+30 kg NPK ha−1 +30 kg N (through biocompost), 45+22.5+22.5 kg NPK ha −1 + 45 kg N (through FYM) and 45+22.5+22.5 kg NPK ha−1 + 45 kg N (through bio-compost) in sub-plots. Results revealed that irrigation 1 day after disappearance of ponded water recorded significantly higher growth and yield attributes viz. plant height, leaf area index, dry matter/plant and grain and straw yield. Similarly, growth, yield attributes and yield significantly increased with 90+45 +45 kg NPK ha−1, which remained at par with 60+30+30 kg NPK ha−1 +30 kg N (FYM), 60+30+30 kg NPK ha−1 +30 kg N (bio-compost) and 45+22.5+22.5 kg NPK ha−1 + 45 kg N (biocompost).
