Assessing mungbean productivity under organic management

Abstract

Background: Now a day’s demand for organic food has increased. Being leguminous, requirement of nitrogen for mung is low. Soil organic matter could affect the soil microbial community and increase the crop growth and yield. In mungbean, roots have symbiotic rhizobia bacteria, which help in fixing atmospheric nitrogen into the soil. Nitrogen plays a major role in synthesis of protein, chlorophyll and plant enzymes of legume. The chemical fertilizers is used in huge quantity which hazards the soil and environment. Synthetic fertilizers have mainly macronutrients in large quantities and cemented the soil for worsening the soil and also the negative impact on crops, livestock and human being. The application of organic sources of nutrients improves the soil physical-chemical condition by adding macro and micronutrients both Methods: A field experiment in Kharif season was conducted at Agronomy field of CCSHAU, Hisar, Haryana, to study the yield, quality and physiological parameters of mungbean under different organic sources. The experiment was conducted with nine treatments viz., T1-RDF, T2-FYM @ 5 t/ha, T3-Vermicompost@ 2.5 t/ha, T4-FYM @ 5t/ha + Rhizobium, T5-Vermicompost @ 2.5 t/ha + Rhizobium, T6-Green manuring +FYM @ 5 t/ha, T7-Green manuring + Vermicompost @ 2.5 t/ha, T8-Green manuring + FYM @ 5t/ha + Rhizobium and T9-Green manuring + Vermi-compost @ 2.5 t/ha + Rhizobium in RBD replicated thrice. Result: Application of recommended dose of fertilizer produced 6.93 and 4.04 percent higher yield as compared to green manuring + FYM @ 5t/ha + Rhizobium and green manuring + vermicompost @ 2.5 t/ha, respectively. The data revealed that the SPAD value of chlorophyll, RWC and LWP was higher with the application of various organic sources over to recommended dose of fertilizer.
