Effect of Weed Management Practices on Different Traits of Wheat
Muhammad Iqbal Marwat

Abstract:
The experiment was laid-out to study the effect of weed management practices on different traits of wheat. The factors were: three varieties; three types of herbicides, broad-spectrum, broad leaf, grassy weeds herbicide and a control plots and row spacings 18, 25 and 32 cm were used. Varieties were assigned to main plots, herbicides kept in subplots and row spacings arranged in sub-sub plots. Broad spectrum herbicide controlled more effectively both grassy and broad leaf weeds and reduced dry weed biomass and increased grain yield ha-1. Effect of varieties on grassy and broad leaf weeds density m-2 was nonsignificant and dry weed biomass was lower in variety Inqilab-91, while grain yield was higher in Bakhtawar-92. In 18 cm row spacing number of grassy and broad leaf weeds m-2 were less as compared to row spacing 25 and 32 cm. Absolute growth rate at 15 days interval was more in variety Inqilab-91 up to 4th cutting, but later on maximum ratio was recorded in Bakhtawar-92 having more tillers m-2. Highest dry matter accumulation was recorded in broad-spectrum herbicide treated plots followed by broad leaf and grassy weed herbicide and control. The absolute growth rate was more in 18 cm row spacing, followed by 25 and 32 cm. It can be concluded that variety Bakhtawar-92 integrated with broad-spectrum herbicide and 18 cm row spacing would minimize weeds density and maximize wheat production.
