Author(s): OP Rajwade and SK Dwivedi
Abstract: The field experiment was carried out at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya Raipur (C.G.) during Kharif season of 2017 to evaluate the effect of drip fertigation on growth and yield of soybean. There were eight treatment T1- 75% RDF through fertigation, T2- 100% RDF through fertigation, T3- 125% RDF through fertigation, T4 - 75% RDF (25 % Basal + 75 % through fertigation), T5-100% RDF (25 % Basal + 75 % through fertigation), T6- 125% RDF (25 % Basal + 75 % through fertigation), T7 -100% RDF through conventional application with drip irrigation, T8- No fertilization with conventional irrigation. The experiment was laid out in randomized block design with eight treatments in three replications. Soybean variety JS 97-52 was sown at a spacing of 30 cm x 10 cm with seed rate of 65 kg ha-1. The results of experiment indicated that various growth parameter like plant height at harvest, dry matter accumulation at 60 and 90 DAS recorded significantly maximum with the application of 125% RDF through fertigation (T3). Application of 100% RDF through fertigation (T2) produced significantly maximum number of pod plant-1, number of seed pod-1, number of seed plant-1, 100 seed weight and seed yield (26.89 q ha-1), while maximum stover yield (32.77) produced with the application of 125% RDF through fertigation (T3) and the minimum growth, yield attributing character and yield were observed under no fertilization with conventional irrigation (T8). In terms of economics, the maximum gross return (82025 Rs ha-1), net return (49301 Rs ha-1) and benefit: cost ratio (1.51) were recorded with the application of 100% RDF through fertigation (T2).
