This research was conducted at Tal Shnan village, located at the eastern of Homs city, Syria during 2012/2013 growing season, using hard local wheat cultivar, Sham 5, to study the effect of seed rates (120, 150, 180, 210 kg/ha), spray with different parts of sorghum water extracts using different, and weeding on wheat yield and weeds accompany with the crop. Results showed that seed rate (180 kg/ha) achieved the highest biological yield and grain yield. Harvest index was increased with increasing seed rate. While, dry weight and number of weeds in 1m2 were decreased with increasing seed rate. Spray with sorghum water extracts (1:10) by 5 L/ha after 60-80 days of sowing caused an increment in biological and grain yields. Also, a decrement in dry weight and number of weeds in 1m2. Water extract of the stems achieved the highest values, followed by (stems+roots), then (stems+leaves) extracts, while (leaves+roots) attained the lowest values. This study concluded that sorghum water extract of the stems achieved a significant increment in wheat yield.

Key words: Seed rate, Sorghum water extracts, Weeding, Wheat.
