Effect of Sowing Methods, Weed Management and Growth Promoters on Yield and Quality Behavior of Kharif Maize (Zea mays L)

Abstract

The present investigation was carried out during two consecutive kharif season in years 2022 and 2023 at students. Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U. P). The experiment was laid out in Split Plot Design keeping sowing methods in main plot and weed management practices in sub plots with growth promoters in sub – sub plots with three replications. There was two sowing methods viz; Conventional methods (S1) and Ridge methods (S2). Whereas weed management practices were five, viz; Weed Free (W1), Weedy Check (W2), Atrazine Pre-emergence @ 1.25 Kg /ha (W3), Halosulfuron methyl Post-emergence @ 65g a.i./ha (W4), Atrazine Pre-emergence @ 0.75 l/ha + Halosulfuron methyl Post-emergence @ 35g ai./ha (W5). and there was Growth promoters’ practices were three viz; Gibberellic acid (Sayish) (G1), Amino acid + Humic acid (Spring ever) (G2), Cytokinins + Enzymes (Ambition) (G3). The experiment was shown on 10th July during 2022 and 13rd July during 2023 using hybrid maize DKC-9144. The crop was harvested at full ripe stage on 11 October and 14 October, in 2022 and 2023, respectively. The highest grain yield, biological yield, stower yield, harvesting index, protein content and protein yield was found under the treatment of S2 (Ridge method) in sowing method, treatment W2 (weed free) in weed control methods and treatment G3 (Cytokinins + Enzymes) in plant growth promotor.
