Abstract
Imigation at 0.6 IW/CPE ratio recorded higher yield of tuber in cassava and pod and hauim in groundnut. Among the combinations, cassava raised as sole crop or as comrade cropping in groundnut recorded comparable yields. Coir waste applied @ 10 t. ha" increased the cassava tuber and groundnut pod yields. The quality of cassava tuber such as starch and total sugar contents increased and HCN content decreased as the moisture level increased. Nutrient up take was the highest under higher moisture regimes. Cassava raised as comrade cropping in groundnut registered maximum uptake of N, P and K. Application of coir waste 10 t.ha" increased the quality characters and total uptake of nutrients by the plants.
Key words : Irrigation, Comrade Cropping, Cassava, Groundnut, Yield. Nutrient Uptake.
