Abstract
Mungbean (Vigna radiata) is an important pulse crop contributing significantly to nutritional security and soil fertility through biological nitrogen fixation. A field experiment was conducted to evaluate the effect of phosphorus levels and organic manures on growth, yield attributes, yield, and economics of mungbean. The experiment consisted of four phosphorus levels (0, 25, 50, and 75 kg ha⁻¹) and three organic manure treatments (control, FYM @ 15 t ha⁻¹, and vermicompost @ 4–5 t ha⁻¹). Results indicated that increasing phosphorus levels significantly improved plant height, dry matter accumulation, number of branches, and nodulation, with maximum values observed at 75 kg P ha⁻¹. Similarly, yield attributes such as number of pods plant⁻¹ (29.58), seeds pod⁻¹ (11.04), and test weight (44.57 g) were highest under 75 kg P ha⁻¹, resulting in maximum seed yield (1146 kg ha⁻¹) and net return (Rs. 50,562 ha⁻¹). Among organic manures, vermicompost recorded superior growth and yield parameters, with highest seed yield (1196 kg ha⁻¹), biological yield (3680 kg ha⁻¹), and B:C ratio (2.42). The combined application of phosphorus and organic manures enhanced nutrient availability, root development, and microbial activity, leading to improved crop performance. Therefore, application of 50–60 kg P ha⁻¹ along with vermicompost proved to be the most efficient and economically viable practice for mungbean cultivation.
