Abstract
A field experiment was conducted during rabi 2022 at Block D of the College Farm, Agriculture College, Naira. The experiment was laid out in Split-plot design with three main plots.M1:100% RDF (180-60-60 NPK Kg ha-1) + FYM @10 t ha-1, M2:75% RDF (135-45-45 NPK Kg ha-1) + FYM @10 t ha-1. M3:0% RDF- Control and four sub-plotsS1: Liquid azospirllum+PSB+KRB+ZnSB+@1.25 L ha-1 each at knee high stage, S2: Vermiwash spraying twice @5% at knee high and tasseling to silking stages, S3: Panchagavya spraying twice @3% at knee high and tasseling to silking stages andS4: Drava Jeevamrutham spraying twice @10% at knee high and tasseling to silking stages Results revealed that 100% RDF (180-60-60 NPK Kg ha-1) + FYM @10 t ha-1 (M1) recorded maximum fresh cob yield (16409 kg ha-1) and stover yield (17481 kg ha-1). Among the subplots: Liquid azospirllum+ PSB+ KRB+ ZnSB+@1.25 L ha-1 (S1) recorded maximum fresh cob yield (14091 kg ha-1) and stover yield (15623 kg ha-1). The interaction effect of different doses of RDF and liquid biofertilizers on fresh cob yield, stover yield and HI was found to be nonsignificant. Hence, it can be concluded that different doses of RDF and liquid biofertilizers are advantageous for weet corn cultivation on sandy loam soils of North costal region.
