Abstract

A field experiment was conducted during the rabi season of 2009–10 to study the assessment of SWI techniques with varying nitrogen levels for improving yield and quality of wheat (Triticum aestivum L.). Effect of four spacings (S1: 10 x 20 cm, S2: 15x20 cm, S3: 20 x 20 cm and S4: 22.5 cm line sowing) was studied on three levels of nitrogen (N: 100 kg N/ha, N2: 125 kg N/ha and N3: 150 kg N/ha). The maximum growth, yield attributing characters, grain yield (4,204 kg/ha), straw yield (6,111 kg/ha), grain protein content, available soil nutrients after harvest and net returns (Rs. 35,373/ha) with CBR of 2.95 were obtained from 20 x 20 cm cross sowing technique. Different levels of nitrogen significantly influenced growth, yield attributing characters, yield, grain protein content and available soil nutrients after harvest. The highest grain yield (4,126 kg/ha), straw yield (6,135 kg/ha) and net returns of Rs. 33,791/ha with CBR 2.80 were recorded from 150 kg N/ha. The interaction effects of spacings and nitrogen levels were significant in respect of straw yield and protein content. Highest straw yield (6,765 kg/ha) was obtained at 20 x 20 cm spacing using 150 kg N/ha with net returns of Rs. 38,345/ha.
