Abstract
An experiment was conducted on urdbean during kharif 2021 at Instructional Farm, College of Agriculture, Ummedganj, Kota (Rajasthan). The experiment comprised of 10 treatments viz. (Control, 75% RDF, 100% RDF, 75% RDF + Rhizobium @ 600 g ha-1 seed inoculation, 75% RDF + PSB @ 600 g ha-1 seed inoculation, 75% RDF + Rhizobium @ 600 g ha-1 + PSB @ 600 g ha-1, 75% RDF + 0.1% FeSO4 + 0.5% ZnSO4 at pre flowering and pod formation stage, 75% RDF + 0.1% FeSO4 + 0.5% ZnSO4 at pre flowering and pod formation stage + Rhizobium @ 600 g ha-1, 75% RDF + 0.1% FeSO4 + 0.5% ZnSO4 at pre flowering and pod formation stage + PSB @ 600 g ha-1, 75% RDF + 0.1% FeSO4 + 0.5% ZnSO4 at pre flowering and pod formation stage + Rhizobium 600 g ha-1+ PSB @ 600 g ha-1) was carried out in randomized block design with three replications. Significantly higher plant height at 60 DAS (25.28 cm) and at harvest (34.43 cm), nodules plant-1 (29.22) at 45 DAS, nodule fresh weight (86.31 mg plant-1) at 45 DAS, chlorophyll content (3.19 mg g-1) at 45 DAS and dry matter accumulation (2.71, 5.94 and 9.99 g plant-1) at 30, 60 DAS and at harvest were recorded with application of 75% RDF + 0.1% FeSO4 + 0.5% ZnSO4 at pre flowering and pod formation stage + Rhizobium 600 g ha-1+ PSB @ 600 g ha-1 in urdbean over rest of the treatments. Among these treatments, application of 75% RDF + 0.1% FeSO4 + 0.5% ZnSO4 at pre flowering and pod formation stage + Rhizobium 600 g ha-1+ PSB @ 600 g ha-1 produced maximum seed yield (1269.30 kg ha-1) of urdbean.
