Abstract:
A field experiment was carried out with an objective to study the effect of fertility levels in dry matter of urdbean [Vigna mungo (L.) Hepper] at Agronomy farm, S.K.N. College of Agriculture Jobner, Jaipur (Rajasthan) during Kharif season of 2018 on loamy sand soil. The experiment of fertility levels and microbial inoculation was carried out with 20 treatments that was carried in RBD with three replications. Results revealed that application of 100% RDF significantly increased the growth and yield determining characters of urdbean viz., plant height, number of branches/plant and crop dry matter accumulation at most of the stages, number and weight of root nodules/plant, CGR and RGR, total chlorophyll content, leaf area index, number of pods/plant, grains/pod and test weight over other levels. It also recorded significantly higher grain (1285 kg/ha) over control. However, it showed statistical equivalence with 75% RDF, 50% RDF wherein, the maximum values of most of the growth and yield attributes as well as yield were obtained. Results further indicated that seed inoculation with PGPR + PSB + VAM significantly enhanced the plant height, number of branches/plant, dry matter accumulation, total and effective nodules/plant, fresh and dry weight of nodules, CGR, total chlorophyll content, leaf area index, number of pods/plant, grains/pod and test weight over PGPR, PGPR + PSB, PGPR + VAM and control. It also produced the highest grain yield (1285 kg/ha).
