Abstract

A field experiments were conducted during rabi 2015-16 and 2016-17 at SKUAST-Jammu, J&K UT to find out the effect of sowing environments and nitrogen levels on performance of varieties of wheat. Three varieties HD 2967, RSP 561 and WH 1105 with three sowing environments 25th October (early), 14th November and 4th December and three levels of nitrogen, viz. 100, 125 and 150 kg/ha replicated thrice in split split plot design. Among the varieties, WH 1105 recorded significantly higher yield than HD 2967 and RSP 561. Early sowing (25th October) of wheat produced statistically higher grain, straw and biological yield values than normal (14th November) and late sowing (4th December) environments along with higher yield attributes. The higher nitrogen dose 25 kg (125 kg/ha), than recommended dose (100 kg/ha) exhibited higher yield attributing parameters and yield of wheat crop. Early sowing and WH 1105 also recorded higher net returns and B:C ratio.
