Response of wheat cultivars to herbicides
Abstract
A field experiment entitled “Response of wheat cultivars to herbicides” was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad (U.P.) India during Rabi seasons of 2004-05 and 2005-06 with an object to ascertain the response of wheat cultivars to herbicides. Field trial was laid out in a split plot design with three replications keeping four treatments of herbicides viz., T1-control, T2-isoproturon @ 1.0 kg ha-1, T3-sulfosulfuron @ 25 g ha-1 and T4 – fenoxaprop-p-ethyl @ 80 g ha-1 in main plot and eight wheat cultivars (PBW-154, HUW-234, PBW-343, PBW-443, HUW-468, NW-1012, UP-2003, Raj 3077) in sub plot. The experimental field was kept free from weeds, throughout the life-span of the crop. The herbicides as per treatments were sprayed with the help of manual operated knapsack sprayer fitted with flatfan nozzle using 600 litres water ha-1. Other agronomic practices as per recommendation were adopted. Post-emergence application of sulfosulfuron @ 25 g ha-1, fenoxaprop-p-ethyl @ 80 g ha-1 and isoproturon @ 1.0 kg ha-1 did not show their harmful effects on the performance of different wheat cultivars. Wheat cultivars HUW-468, PBW-443 and PBW-343 were screened out as higher yielder.
