Optimizing Growth and Yield of Cluster Bean (Cyamopsis tetragonoloba L.) Var. Neelam-61 through Integrated Use of Inorganic Fertilizers, Organic Manure and Rhizobium Inoculation

Organic matter decomposition is beneficial to plant growth and development. However, the overuse of chemical fertilizers poses risks to environmental sustainability and long-term soil health. The integration of organic fertilizers, such as poultry manure, offers a promising solution to reduce dependency on chemical inputs while maintaining crop productivity. The field experiment was conducted at Research Farm of the Department of Soil Science, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj U.P during Kharif season of 2023. An experiment was conducted in Factorial Randomized Block Design (FRBD) with three levels of N:P:K, Poultry manure and two levels of Rhizobium inoculation. The seeds were treated with Rhizobium. Based on the experimental data, the application of 100% Recommended Dose of Fertilizer (RDF), 100% Poultry manure and 100% Rhizobium inoculation not only resulted in maximum growth and yield attributes but also proved to be significantly superior to all other treatments.
