The present study was undertaken during 2013-14 and 2014-15 at Chaudhary Charan Singh research farm Hisar, to find out the effect of date of sowing and nitrogen levels on growth, yield, nitrogen uptake and nutrient use efficiencies in western Haryana. The results revealed that plant height, dry matter accumulation, Siliquae per plant, number of seeds of siliqua and 1000 seed weight decreased with each delay in sowing. The seed yield decreased by and % over November 15, and over November 5, and over October 25 in October 15 (2683 and 2586 kg/ha) during both 2013-14 and 2014-15, respectively. | Yield nitrogen uptake and nutrient use efficiency in Indian Mustard Brassica juncea L. as effected by date of sowing and nitrogen levels in Western Haryana India
