Abstract
A field experiment was conducted to study the productivity and profitability enhancement of maize (Zea mays L.) through nutrient management during summer, 2016 at the experimental farm, Department of Agronomy, Faculty of Agriculture, Annamalai University. The experiment was laid out at randomized block design (RBD) having three replications. The result revealed that highest green cob yield of 9579 kg ha-1 was recorded in the treatment T6 (150% RDF + Micronutrient mixture soil application @ 25 kg ha-1) and it was superior to other treatments. The result also revealed that highest net return was recorded in the treatment T6 (150% RDF + Micronutrient mixture soil application @ 25 kg ha-1) and it was superior than other treatments. This treatment also significantly recorded higher gross return and benefit cost ratio of maize.
