Effect of liquid organic supplements on growth and yield of maize (zea mays l.)

A field experiment was conducted during July to October, 2015 under deep clay soil at the Experimental farm, Faculty of Agriculture, Annamalai University to study effect of foliar nutrition on growth and yield of maize. The experiment was conducted in randomized block design and replicated thrice. The experiment comprised of ten treatments viz., control (water spray), liquid organic supplements Jeevamrutha, Beejamrutha, Vermiwash at 3 and 5% concentration applied 3 times on 20, 40 and 60 DAS. The results of the experiment showed that foliar spray of 5 % Jeevamrutha on 20, 40 and 60 DAS significantly recorded higher growth, yield attributes and yields of maize viz., plant height, leaf area index (LAI), dry matter production (DMP), cob length and cob diameter, number of grains cob-1, test weight, grain and stover yield. Significantly lowest values for growth attributes, yield attributes, grain and stover yields of maize were recorded under control. Based on the above, it could be concluded that, foliar spray of 5% jeevamrutha on 20, 40 and 60 DAS would help to increase productivity and profitability of maizeunder Cauvery delta region of Tamil Nadu.
