A field experiment was conducted during the Rabi season of the year 2009-10 to study the yields and economics of wheat (Triticum
aestivum L.) influenced by SWI techniques with varying nitrogen levels . Effect of four spacings (S1: 10 x 20 cm, S2: 15 x 20 cm, S3: 20 x 20 cm
and S4: 22.5 cm line sowing were) studied on three levels of nitrogen (N1:100 kg N ha-1, N2:125 kg N ha-1 and N3:150 kg N ha-1). The higher grain
yield (4,205 kg ha-1), straw yield (6,111 kg ha-1), the highest gross realization (Rs. 53,509 ha-1), net realization (Rs. 35,373 ha-1) with CBR (2.95)
were obtained from 20 x 20 cm cross sowing technique. Different levels of nitrogen significantly influenced yields, gross realization, net
realization with CBR. Higher grain yield (4,126 kg ha-1), straw yield (6,135 kg ha-1) and gross realization (Rs. 52,577. ha-1), net realization (Rs.
33,791 ha-1) with CBR (2.80) were obtained from 150 kg N ha-1 . Treatment combination S3N3 gave maximum straw yield, gross return, net
return with CBR.
