Effect of organic nutrient management on maize production under South Gujarat condition

The field experiment was carried out on Certified Organic Farm of ACHF, Navsari Agricultural University, Navsari during 2012-13 to find out the effect of different organic sources on growth, yield, nutrient content and uptake by maize crop. The treatment containing application of 50% NADEP compost + 50% castor cake on equivalent N basis of RDN recorded significantly higher plant height, cob length, cob girth, cob weight, number of grains per cobs, grain and stover yield of maize. Significantly higher total N, P, K and S contents and its uptake were also found under treatments containing 50% NADEP compost + 50% castor cake on equivalent N basis of RDN than other treatments.
