  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.

  The effect of various management options like herbicide types and varying spacings on economic traits in wheat were studied. The factors included were: three varieties, three types of herbicides-broad-spectrum, broad leaf, grassy leaf herbicide and a control plots following row spacings of 18, 25 and 32 cm. The biological, grain and straw yield, net income and cost benefit ratio were significantly affected by varieties, herbicides and row spacings. Interaction between varieties and row spacings was significant for biological and grain yield and net income. Among varieties Bakhtawar-92 had maximum biological yield, grain yield, straw yield, net income and benefit cost ratio over Ghaznavi-98 and Inqilab-91. In case of herbicide treatment, broad-spectrum herbicides had higher biological yield, grain yield, straw yield, net income and benefit cost ratio over broad leaf, grassy leaf herbicide and weedy check. Within row spacing, 18 cm space had maximum biological yield, grain yield, straw yield, net income and benefit cost ratio over 25 and 32 cm row spacings, respectively. In the interaction of varieties and row spacing, highest had been found in var. Bakhtawar-92 with 18 cm row spacing for biological yield (14.81 t ha-1), grain yield (4.93 t ha-1) and net income (Rs. 37894 t ha-1). It is concluded that for integrated weed management in wheat, variety Bakhtawar-92, broad-spectrum herbicide and 18 cm spacing may be integrated.
