Abstract

                                The Influence of management practices like intercropping, planting patterns and weeding Intervals on weed infestation and grain yield of sorghum were studied. Sole sorghum was a poor competitor with weeds but the competitive ability of cowpea Intercropping with sorghum reduced the weed growth considerably. Weed free situation upto 15 days may be suflicient for obtaining optimum grain yield and net monetary returns from sorghum cowpea Intercropping system, whereas weed free upto 30 days was essential for sorghum intercropped with green gram or groundnut. The planting patterns had no impact on weed infestation and total grain yield.

Key words : Intercropping. Planting pattern, Weeding interval Grain yield, Sorghum.
