Abstract:
A field experiment was conducted during kharif season of 2020 at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, to study the "Effect of nutrient management on growth and yield attributes of horsegram in loamy sand soil. The experiment comprised of twelve treatments viz., T₁: 75% RDF, T₂: 100% RDF, T₃: 125% RDF, T₄: 75% RDF + 500 ppm thiourea at branching, T₅: 75% RDF + 500 ppm thiourea at pre-flowering, T₆: 75% RDF + 500 ppm thiourea at branching and pre-flowering, T₇: 100% RDF + 500 ppm thiourea at branching, T₈: 100% RDF + 500 ppm thiourea at pre-flowering, T₉: 100% RDF + 500 ppm thiourea at branching and pre-flowering, T₁₀: 125% RDF + 500 ppm thiourea at branching, T₁₁: 125% RDF + 500 ppm thiourea at pre-flowering and T₁₂: 125% RDF + 500 ppm thiourea at branching and pre-flowering were evaluated in randomized block design replicating three times. Significantly higher plant height, number as well as dry weight of root nodules, number of branches per plant, number of pods per plant, pod length and number of seeds per pod of horsegram were recorded under treatment T₁₂ which was found at par with treatment T₆. In the case of days to 50% flowering, days to maturity, seed index and harvest index, treatments did not affect significantly. Significantly, higher seed yield (770 kg/ha) and stover yield (2292 kg/ha) were achieved with application of 125% RDF + 500 ppm thiourea at branching and pre-flowering (T₁₂) which remained at par with treatment T₆.
