Response of nitrogen scheduling and weed management on growth and yield attributes of wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted to study response of nitrogen scheduling and weed management on growth and yield attributes of wheat (Triticum aestivum L.) at the Experimental Farm, Mata Gujri College, Shri Fatehgarh Sahib during Rabi season of year 2018-2020. The experiment laid out in Split Plot Design (SPD) with three replications. The nitrogen scheduling includes N1 -½ Basal + ¼ at 4WAS + ¼ at 8 WAS, N2 -⅓ at 4 WAS + ⅓ at 8 WAS + ⅓ at 10 WAS, N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS while weed management treatment were W2 -clodinafop @ 60 g/ha, W3 -sulfosulfuron @ 25 g/ha, W4-carfentrazone @ 20g/ha along with weed free and weedy check. The results revealed that the maximum growth and yield attributes were recorded of N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS which was at par N2 -⅓ at 4 WAS + ⅓ at 8 WAS + ⅓ at 10 WAS and found significantly superior over N1-½  Basal + ¼ at 4WAS + ¼ at 8 WAS.N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS + W3 -sulfosulfuron @ 25 g/ha recorded significantly maximum which was significantly superior over all the treatments.
