A study to investigate the efficacy of different herbicides
on rainfed wheat was carried out at the experimental farm,
of the University of Arid Agriculture, Rawalpindi during
2004 to 2007. Wheat variety GA-2002 was planted as a test
crop. The experiment was carried out in randomized complete
block design (RCBD) with three replications. Among different
treatments, the lowest weed biomass was achieved in hand
weeding treatment. Plots treated with herbicide Buctril
super (Bromoxonil + MCPA) also produced excellent results in
reducing weed biomass. The highest grain yield was recorded
in plots where Buctril Super was sprayed. Weedy check
treatment was at the bottom with the lowest grain yield.
Economic analysis indicated that Buctril super was the best
treatment with the highest benefit cost ratio.
Key words:
Wheat, weed control, herbicides, rainfed conditions. |
