Effect of polymer seed coating and seed treatment on seed quality parameters and yield attributing characters of hybrid maize (Zea mays L.)

The experiment was conducted in Post Graduate Seed Testing Laboratory, Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during kharif season 2018. Effect of polymer seed coating and seed treatment on seed quality parameters and yield attributing characters of hybrid maize consisted of 12 treatments with four replication in lab. The seeds were coated with Polymer@ 3g kg-1 seed in combination with fungicides (Thiram@ 2g kg-1 seed, Bavistin@ 2g kg-1 seed, Captan@ 3g kg-1 seed) and insecticide (Imidacloprid@ 5g kg-1 seed, Chloropyriphos@ 3g kg-1 seed) and maintained untreated seeds (control). The results of the present investigation revealed that T7 (with polymer coating + Seed treatment with Thiram @ 2g kg-1 seed) was found to be significantly superior viz., Germination Percentage (92.75), Seedling Root Length (11.28cm), Seedling Shoot Length (3.19cm), Seedling Length (14.47cm), Seedling Fresh Weight (1.47g), Seedling Dry Weight (0.40g), Seed Vigour Index-I (1341.99), Seed Vigour Index-II (37.10). | Effect of polymer seed coating and seed treatment on seed quality parameters and yield attributing characters of hybrid maize (Zea mays L.)
