Impact of organic and inorganic sources of nutrition on the morpho-physiological, biochemical, yield traits and uptake of nutrients by mung bean (Vigna radiata L.)

Mung bean is a vital legume crop in Pakistan, contributing significantly to both dietary needs and agricultural sustainability due to its rich nutrient content and soil-enhancing properties through nitrogen fixation. This study aimed to evaluate the impact of vermicompost, simple compost and NP fertiliser on the morpho-physiological, biochemical and yield characteristics of mung bean. Treatments included vermicompost, compost and their combinations with NP fertiliser. Key parameters assessed were plant height, crop germination, leaf size, nodule viability, pod length, grain protein content and yield attributes. Results indicated that while vermicompost alone improved growth and productivity, the combination of 50% vermicompost with 50% NP fertiliser yielded the highest productivity. Intermediate results were observed with a mixture of 25% vermicompost, 25% compost and 50% NP fertiliser, whereas the control (100% NP fertiliser) and compost treatments alone resulted in the lowest productivity and decreased soil fertility. The study concluded that integrating organic and chemical fertilisers, particularly at a 50:50 vermicompost to NP fertiliser ratio, is optimal for enhancing mung bean yield and soil health.
