A field experiment was conducted at Water Management Research Centre, Belavatagi during 2004-06 for three years to study the effect of nutrients substituted through organics. The results indicated that substitution of nitrogen through organics in maize was not sufficient in sustaining the grain yield for the first two years. In third year only substitution of 50 % N through organics gave higher grain yield (6.21 t/ha) and was comparable with 100 % inorganics fertilizer + 10 t FYM/ha (6.14 t/ha). However on pooled basis, application of 100 % inorganics fertilizer + 10 t FYM/ha (6.35 t/ha) gave significantly highest grain yields. In chickpea phosphorus was substituted through organics and yields were not affected significantly in two years out of three. On pooled basis, substitution of phosphorus (50%) through organics gave higher yields (1.59 t/ha) and was comparable with 100 % inorganic fertilizer
