Type: article
Abstract: A field experiment was conducted during the rabi season of 2017 in wheat crop (var. HUW-234) at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Allahabad (U.P.). The experiment was laid out in a Randomized Block Design with 12 treatment combinations, consisting of three nitrogen levels (100,125 and 150 kg N/ha) on soil test basis (STB) compared to farmer practice (FP) and nitrogen management viz. 100% N through urea, 75% N through urea + 25% N through vermicompost with seed inoculation by Azotobacter. The experimental result reveals this saving of nitrogen by 16.5 to 31.7 kg/ha without any significant effect on growth and yield of wheat was noticed. The growth parameters viz. plant height, no. of tillers/running row meter, Crop-growth rate (CGR), and Yield attributes viz. No. of effective tillers/m2, grains/spike and grain yield (4.57 t/ha) were significantly higher with 150 kg N/ha (Farmer Practice) when applied 100 % N through urea, where as plant dry weight, leaf area index (LAI) and straw yield (7.63 t/ha) were significantly higher with 150 kg N/ha (Farmer Practice) when applied 75% N through urea + 25% N through vermicompost + Azotobacter (Seed inoculation).
