Abstract
Wheat cultivation in Pakistan is carried out on more than half area in rain fed condition. To improve the average yield of country the only possible reason is to enhance productivity of wheat crop in dry areas. Current study response of wheat productivity to ridge sowing method and nitrogen levels was studied in rain fed condition at the research farm of The University of Swabi, during 2015-16. The experiment was carried out in split plot design having four replications. Sowing methods were assigned to main plot while nitrogen levels were allotted to sub plot factors. It was observed that on ridge bed sowing method tiller per meter square (256), productive tiller (216.55), thousands grains weight (46.110), biological yield (8549.1), grain yield (2429.5) and harvest index (33.50) were significantly increases over flat method. In case of nitrogen application maximum tiller per meter square (240.12 Numbers), productive tiller (240.12 Numbers), thousands grains weight (59.70 g), biological yield (7388.7 kg ha-1), grain yield (2396.96 kg ha-1) and harvest index (32.50) were recorded in plots receiving nitrogen at the rate of 120 kg ha-1. Thus it is concluded that sowing of wheat on ridges produces maximum yield as compare to flat sowing and nitrogen application at the rate of 120 kg N ha-1 had higher yield than rest therefore it is recommended that wheat sowing on ridges with the application of 120 kg N ha-1in rainfed areas can improve the wheat productivity in Pakistan.
