Abstract :
The impact of phytotoxicpotential of sorghum formations and herbicide application along with their comparative economic advantages over each other in the wheat crop, was evaluated in present filed study. The sorghum formulations with their application volumes were as i) the water soaked extract (330 L ha-1), ii) water boiled extract (15, 20, 25 or 30 L ha-1), iii) fine powdered (270, 360, 450 or 540 g ha-1).Most of the sorghum formulations controlled weed density in array 24-61%. The weeds dry weight was declined by 20-59% and crop yield raised upto25%. The water soaked extract at a volumeof 330 L ha-1and water boiled extract at 20 L ha-1volumewere not only useful in weed controlbut also enhanced yield and demonstrated economic profitability.These treatments provided higher rates of marginal returns % 154.54 $ and 47.70 $, respectively. Although, sorghum powder were effective in weed control but were uneconomical because of their highproduction cost.
