Abstract

An experiment to study the impact of integrated weed management strategies in wheat was carried out at agronomic research area, faculty of agriculture, Gomal University, Dera Ismail Khan, during the year 2010-2011. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and ten treatments. The net plot size was kept as 5 m × 2 m (10 m²). The treatments included single, double and triple hoeing with kasola. 3-hoeing with khurpa, puma super applied at 1st and 2nd irrigation. Sonic, Buctril super, weed control throughout the season and no weeding (check). The results revealed that the application of herbicides and hoeing significantly affected the weed biomass (g m^-2), number of tillers (m^-2), spike length (cm), 1000-grain weight (g), grain yield (t ha^-1), and biological yield (t ha^-1). Weed free crop throughout the season it remains on top more than grain and biological yield gave the highest grain yield (6.167 t ha^-1) and biological yield (11.42 t ha^-1). Among various herbicides, Buctril super recorded maximum grain yield (4.767 t ha^-1) and biological yield (9.953 t ha^-1). The lowest Cost-Benefit Ratio (0.33) was recorded in Buctril super treatment.
