Productivity and Quality of Urdbean (Vigna mungo L.) Influenced by Fe, Zn and Bio-Fertilizers

A field experiment was conducted on burban during kharif 2021 at Instructional Farm, College of Agriculture, Ummedganj, Kota (Rajasthan). The experiment comprised 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 @ 600g ha-1 + PSB @ 600 g ha-1seed inoculation, 75 % RDF + 0.1 % FeSO4 + 0.5 % ZnSO4 foliar spray at pre-flowering and pod formation stage, 75 % RDF + 0.1 % FeSO4 + 0.5 % ZnSO4 foliar spray at pre-flowering and pod formation stage + Rhizobium @ 600 g ha-1, 75 % RDF + 0.1 % FeSO4 + 0.5 % ZnSO4 foliar spray at pre pre-flowering and pod formation stage + PSB @ 600 g ha-1, 75% RDF + 0.1 % FeSO4 + 0.5 % ZnSO4 foliar spray 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. The maximum pods plant-1 (34.26), and seeds pod-1(6.93) were recorded with the application of 75% RDF + 0.1 % FeSO4 + 0.5 % ZnSO4foliar spray at pre flowering and pod formation stage + Rhizobium 600 g ha-1+ PSB @ 600 g ha-1 seed inoculation in urban over rest of treatments. Application of 75% RDF + 0.1 % FeSO4 + 0.5 % ZnSO4foliar spray at pre flowering and pod formation stage + Rhizobium 600 g ha-1+ PSB @ 600 g ha-1seed inoculation produced significantly higher seed yield (1269), straw yield (1512) and biological yield (2782)kg ha-1of urdban during course of experimentation as compared to remaining treatments. Harvest index and test weight did not significantly influence by various treatments of Fe, Zn and Bio-fertilizers. Significantly higher protein content (24.19%) and protein yield (309 kg ha-1) in urban seed were recorded with the application of 75% RDF + 0.1 % FeSO4 + 0.5 % ZnSO4foliar spray at pre flowering and pod formation stage + Rhizobium 600 g ha-1+ PSB @ 600 g ha-1 seed inoculation over rest of treatments. The maximum net returns (₹ 81964/- ha-1) and B: C ratio (3.44) were obtained with the application of 75% RDF + 0.1 % FeSO4 + 0.5 % ZnSO4 foliar spray at pre flowering and pod formation stage + Rhizobium 600 g ha-1+ PSB @ 600 g ha-1seed inoculation.
