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

Abstract

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.
