Abstract:
The particulars of experimental material used and techniques adopted during the course of investigation entitled ^“Find out the suitable method of nitrogen application in wheat (Triticum aestivum) crop”. Field experiment was carried out during rabi season of 2021-22 at Agricultural Research Farm of Faculty of Agriculture sciences and allied Industries Rama University, Mandhana Kanpur (U.P). The experiment was laid out in Randomized block design with three replications keeping seven nitrogen management practices Control, 50% N as basal + 50% N after 1^st irrigation, 50% N as basal + 25% N after 1^st irrigation + 25% N after 2^st irrigation, 25% N as basal + 25% N after 1^st irrigation + 25% N after 2^st irrigation+ 25% N after 3^st irrigation, 75% N through vermicompost + 25% N as basal, 50% N through vermicompost + 50% N as basal, 50% N through vermicompost + 25% N as basal + 25% N after 1^st irrigation. Results revealed that among weed management practices weed free followed by Sulfosulfuron (30g) + metsulfuron (4g) a.i ha^-1 proved as superior than other treatments with respect to higher crop growth and yield attributes where as plant height, number of tillers m^-2,, grain per spike, grain weight per spike(g), grain and straw yield (q/ha). Maximum gross return and cost of cultivation was found with 50% N through vermicompost + 25% N as basal + 25% N after 1^st irrigation. While maximum net return was found with 50% N through vermicompost + 25% N as basal + 25% N after 1^st irrigation. Maximum B:C ratio was obtained in combination of 50% N through vermicompost + 25% N as basal + 25% N after 1st irrigation. The planting was done on 4^th December 2021. Among the various nitrogen management treatment 50% N through vermicompost + 25% N as basal + 25% N after 1^st irrigation recorded highest B:C ratio and yield.
