Effect of different methods of fertilizer application to wheat after germination under rainfed conditions

Abstract

Different methods of application of N and P fertilizer after rainfall were compared with no fertilizer application at the time of wheat sowing (cv. GA- 2002). The data regarding flag leaf area, number of grains per spike, 1000-grain weight and grain yield were recorded. The preliminary studies revealed that fertilizer application with rain after germination (45 days after sowing) increased wheat yield by 32.16 percent when only nitrogenous fertilizer was applied (90 kg N/ha) as side dressing. A yield increase of 42.65 percent was recorded when both nitrogenous and phosphatic fertilizers (90-60 kg/ha) were applied by broadcast and 44.05 percent increase in case of same fertilizers applied as side placement as compared to control. The dose of 90kg N per hectare of nitrogenous fertilizer was found economical in terms of net profit when applied by broadcast method.
