Effect of Intercropping and Nutrient Management on Weed Control and Yield in Cassava Based Production Systems

A field experiment was conducted to evaluate the effect of red gram intercropping and nutrient management practices in cassava on weed control and yields at the College of Agriculture, Vellayani during May 2022 to May 2023. The experiment was laid out in randomised block design with three replications and ten different nutrient management practices (different doses of recommended dose of fertilizer and plant growth promoting rhizobacteria) and a control of no nutrient addition in cassava. The results revealed that intercropping was effective in limiting weed population compared to the sole cropping and were significant from second month after planting. Yield of the intercropping system computed as cassava equivalent yields and economics were higher for treatments involving PGPR application.
