Integrated Use of Organic Manure and Inorganic Fertilizers for Improving Growth, Yield and Economics of Mung Bean (Vigna radiata L.)

Abstract

Aim: The field experiment was undertaken to study the effect of organic and inorganic fertilization on growth, yield and economics of mung bean production. Design: The data were statistically analyzed using analysis of variance (ANOVA) with the aid of Web Agricultural Statistics Software Package appropriate for RBD. Place and Duration of Study: The experiment was undertaken during kharif season of 2024-25 at the Agriculture Research Farm, Faculty of Agriculture, Arunachal University of Studies, Namsai, Arunachal Pradesh. Methodology: The treatment comprises the combination of Farm Yard Manure (FYM) and inorganic fertilizers, i.e. 1 t FYM    ha-1 + 100% RDF (15:35:15 NPK ha-1), 0.75 t FYM ha-1 + 75% RDF, 0.5 t FYM ha-1 + 50% RDF and 5 t vermicompost ha-1 and control. Results: Results showed that the integration of organic manure and chemical fertilizers viz. of 1 t FYM ha-1 + 100% RDF (15:35:15 NPK ha-1) significantly improved the plant height (53.71 cm), number of branches (9.92), number of pods per plant (18.03), number of seeds per pod (11.09), pod length (12.04 cm), seed yield per plot (1195.6 g) and biological yield (2091.6 g) in comparison to other treatments. The highest harvest index (57.10 %) and benefit- cost ratio (2.91) were also recorded with the application of 1 t FYM ha-1 + 100% RDF (15:35:15 NPK ha-1). Conclusion: Thus, integration of organic and inorganic application emerged as the most effective strategy for boosting mung bean productivity under sandy loam soils of Arunachal Pradesh.
