Abstract
According to study, durum wheat (Triticum durum Desf.), is an important food crop in the world, with an estimated annual production of 36 million tons. Randomized complete block design was employed. With a relative density 74.6%, broadleaved weed species were the most dominant followed by grasses with relative density of 24.3%. Number of tillers per plant, plant height, Grains per spike, aboveground biomass yield, and grain yield were affected by the interaction of weeding frequency and spacing. Spacing and Weeding frequency were significantly affected days to heading, spike length, thousand grain weight and harvest index. Wider spacing, four wedding and control weeding frequencies had significantly yield components of durum wheat. Highest dry biomass weight was achieved by treatments with 10 cm row spacing for both grass and wide weed species. As study sowing durum wheat with 30 cm row spacing and keeping it completely weed free resulted in optimum growth and grain yield.
