Abstract
The impact of phytotoxic potential 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 upto 25%. The water soaked extract at a
volume of 330 L ha-1
and water boiled extract at 20 L ha-1
volume were not only useful
in weed control but 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 high production cost.
