Impact of Different Seed Priming Methods with Bio Fertilizers and Botanicals on Growth, Yield and Yield Attributing Traits of Sweet Corn (Zea mays L.)

Abstract

A field experiment was conducted during Rabi season of 2021-2022 at Field Experimentation Center of Department of Genetics and Plant Breeding, SHUATS, Prayagraj, U.P. The experiment was laid out in Randomized Block Design, with a view to find out the suitable Seed priming methods with bio fertilizers and botanicals on growth, yield and yield attributing traits of Sweet corn (Zea mays L.). For this purpose, 13 priming methods including control were used to study under field conditions. The results indicated that Field emergence percentage at 4,7, and 10 DAS, Plant height at 30, 45, 60 and at harvest DAS, Days to 50% Tasselling, Days to 50% Silking, Days to Maturity, Cob length (cm), Cob girth (cm), Number of cobs per plant, Number of rows per cob, Number of grains per row, Seed index (g), Seed yield per plant (g), Seed yield per plot (t/ha), Stover yield (t/h), Biological yield (t/ha) and harvest index (%), were significantly recorded highest in Azospirillum @ 30g (12 hours) followed by Azospirillum @ 20g (12 hours) when compared to other treatments. It is suggested that seed priming with Azospirillum @ 30g (12 hours) is used for improving growth, yield and yield attributing traits of sweet corn could be recommended.
