Effect of broad leaf herbicides on density and dry weight of weeds, yield and yield attributes of irrigated wheat

Abstract

Experiment was carried out during rabi 2016-17 under All India co-ordinate Wheat & Barley Improvement Project, at BTC, College of agriculture and Research Station Sarkanda, Bilaspur (C.G.). The highest yield was obtained under weed free situations (45.98 q/ha). A close comparison among herbicides shows better performance of Metsulfuron + carfentrazone + surfactant (44.95 q/ha) followed by Halauxifen methyl + florasulam+ carfentrazone + surfactant (44.56 q/ha) and 2,4-D E + Carfentrazone (42.02 q/ha). Gain in yield was due to better weed control as a result higher number of earheads/sq.m. This treatment also reduced weed number and dry weight to great extent a compared to other treatments.
