Abstract
The present investigation entitled “Productivity and economics of soybean as influenced by fertigation on different growth stages” was carried out during Kharif season of 2016 at the Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyala, Raipur. The experiment was laid out in randomized block design (RBD) with three replications. The treatment comprised nutrient combination of T1 - 50% RDF as basal + 50% RDF through Fertigation at flowering, T2 - 50% RDF as basal + 50% RDF through Fertigaion at pod initiation, T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling, T4 - 100% RDF as basal + Irrigation at flowering, T5 - 100% RDF as basal + Irrigation at pod initiation, T6 - 100% RDF as basal + Irrigation at grain filling, T7 -100% RDF as basal. The soil of the experimental field was clayey in texture (Vertisols) with low N, medium P and high K content.
Growth parameters like Plant height, number of leaves and dry matter accumulation, number of branches per plant, crop growth rate and relative growth rate were maximum under treatments T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling and minimum was under T7 - 100% RDF as basal. Yield and yield parameters like number of pods per plant, number of seeds per pod, number of seeds per plant, rain fall use efficiency, seed and stover yield were maximum recorded under the treatments T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling, minimum was under T7 - 100% RDF as basal. Higher N, P, K, uptake by plant was recorded under the T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling, as a compared to other treatments of fertigation and the lowest N, P, and K uptake by plant was recorded under T7 - 100% RDF as basal. Economics of soybean production in terms maximum gross return (Rs. 84708 ha-l), net return (Rs.64756 ha-l) and benefit: cost ratio (3.25) was recorded under T3 - 50% RDF as basal +50% RDF through fertigation at grain filling in soybean.
