Field experiments were conducted to find out the effect of intercropping and organic manures on the nutrient uptake and soil fertility of cassava intercropping systems at Veterinary College and Research Institute Farm, Namakkal during 2001 and 2002. The popular hybrid of cassava H 226 was tried as test crop. Three intercropping systems viz., sole cassava, cassava + maize (var. African tall) and cassava + cowpea (var. CO 5) were assigned to main plots. Six organic manorial treatments viz., FYM (25 t ha-1), Poultry manure (10 t ha-1), composted poultry manure (10 t ha-1), FYM (12.5 t ha-1) + poultry manure (5 t ha-1), FYM (12.5 t ha-1) + composted poultry manure (5 t ha-1) along with control (no organic manure) were assigned to sub plots. The study revealed that sole cassava had higher uptake of all nutrients (N, P and K) followed by cassava intercropped with cowpea. Among the organic manures, composted poultry manure either alone or with FYM had higher uptake. The depletion of soil nutrients was lesser in sole cassava followed by cassava intercropped with cowpea. Among the organic manures, composted poultry manure recorded higher soil nutrients. The N balance in the systems showed a lesser depletion of soil N due to cowpea intercropping and a higher depletion of soil N due to maize intercropping. Among organic manures, composted poultry manure depleted the soil nutrients, the least.
