Nutrient removal and nutrient balance in soil under different systems of cassava-peanut intercropping were evaluated. The experiment was set up to compare the planting systems of (1) cassava planting spaced 100*100 cm + peanut 1 row, (2) cassava planting spaced 200*50 + peanut 2 rows, (3) cassava planting spaced 200*50 cm + peanut 3 rows, (4) sole cassava spaced 100*100 cm, and (5) sole peanut spaced 50*20 cm. The results showed that cassava-peanut intercropping systems removed more N, P, and K than sole cassava. The treatment of cassava + peanut 1 row removed the greatest amount of N, P and K. In term of nutrient balance in soil when peanut stover was incorporated into the soil, cassava-peanut intercropping at different row arrangement produced less negative balance for N tha that of sole cassava. Cassava-peanut intercropping and sole cassava produced the positive balance for P, and negative balance of K. Sole cassava resulted the most negative balance of K in soil.
