Abstract

Cluster bean is a legume crop, which requires minimum level of nitrogen but need to be supplemented with proper dose of nitrogen, phosphorus and potassium fertilizers for better growth and development. Being a drought tolerant crop, its cultivation in marginal lands with little or no inputs contribute to its poor productivity and quality. Thus, the present investigation was conducted to evaluate the effect of application of liquid bio-fertilizers [Rhizobium, phosphorus solubilizing bacteria (PSB) and potassium solubilizing bacteria (KSB)] in combination with three different levels of recommended dose of fertilizer (100%, 75% and 50%) and organic manures (FYM and Vermicompost) on quality of cluster bean [Cyamopsis tetragonoloba (L.) Taub.]. The study was carried out during 2022 in a Randomized Block Design (RBD) with 11 treatments in three replications. The quality attributes of cluster bean pods viz., crude fibre, crude protein, shelf life and dry pod weight were found to be improved in plants treated with application of 75% RDF ha-1 + Vermicompost 5 t ha-1 + Rhizobium, PSB, KSB each at 20 ml kg-1 seeds + PPFM 1% at 30th and 60th DAS (T10).

Conclusion

Crude protein, shelf life and dry pod weight were found to be higher with lesser crude fibre content in cluster bean pods when applied with 75% RDF ha-1 + Vermicompost 5 t ha-1 + Rhizobium at 20 ml kg-1 seeds + PSB at 20 ml kg-1 seeds + KSB at 20 ml kg-1 seeds + PPFM 1% at 30th and 60th DAS (T10). Therefore, it could be concluded that treatment combination T10 could be adopted to improve the quality of cluster bean.
