Fertilizer Management in Pigeonpea Based Intercropping Systems. II. Nutrient Removal and Net Change in Soil Fertility

摘要

An experiment on the effect of fertilizer levels in pigeonpea based intercropping systems was conducted to find out total nutrient removal and the net change in the soil fertility. Pigeonpea + groundnut intercropping system at recommended dose (RD) offertilizer applied to pigeonpea and 50 per cent RD to groundnut recorded highest nutrient removal (508.9 kg/ha). Nutrient balance of N, P and K in the soil after harvest of crops was highest at recommended dose of fertilizer applied to pigeonpea and groundnut.
