Effect of Application of Micronutrients through Polymer Seed Coating on Growth and Yield of Maize Hybrid (RMH-2)

Abstract

Field experiment was carried out in Randomised Complete Block [RCB] design with three replications and 16 treatments in Rabi season at College of Agriculture, Bheemarayanagudi, Yadagir district, Karnataka during 2014-15. Among the treatments, significantly higher plant height at 30, 60 days and at harvest (78.67, 136.33 and 186.00cm respectively), cob length (17.17cm), cob diameter (4.36cm), cob weight (137.67g), number of grains per cob (381.57), grain yield per plant (113.80 g) and grain yield per hectare (57.50 q) were recorded in the treatment with Potassium molybdate + ZnSO4 each @2g per kg of seed. Control recorded significantly lower plant height at 30, 60 days and at harvest (70.00, 115.20 and 173.20 cm respectively), cob length (13.80 cm), cob diameter (3.38 cm), cob weight (119.23 g), number of grains per cob (368.00), grain yield per plant (95.47 g) and grain yield per hectare (52.02q). From this study, it is inferred that coating the seed micronutrients with Potassium molybdate+ ZnSO, each @2g per kg of seed through polymer is beneficial for achieving better growth and higher yield of hybrid maize.
