Abstract: Mungbean (Vigna radiata) has gained increasing significance as a crucial grain legume in Nepal’s tropical and sub-tropical regions due to its short growth cycle and soil fertility enhancement properties. This research was conducted at Agronomy farm of Lamjung campus, to assess how mungbean performs under varying row spacing and Npk fertilizer levels. The study employed two-factorial Randomized Complete Block Design with three row spacing levels (20 cm, 25 cm, and 30 cm) and three NPK fertilizer doses (10:10:10, 20:20:20, and 30:30:30 kg NPK/ha) as treatments. The investigation explored phenological and yield attributing parameters. Interestingly, the outcomes showed that row spacing had negligible impact on root growth attributes, including root length and nodule formation. However, root nodule number increased with higher NPK fertilizer levels, particularly notable with the application of (30:30:30) kg NPK/ha, resulting in the highest nodules per plant (140.40), while the lowest nodules (91.35) were observed with (10:10:10) kg NPK/ha. Vital traits like plant height, branch and leaf counts, pod set, pod length, and seed weight were unresponsive to both NPK doses and row spacing levels. In contrast, grain yield exhibited a substantial increase with NPK fertilizer application, with the highest yield (1263.55 kg/ha) achieved with (30:30:30) kg NPK/ha and the lowest (929.27 kg/ha) with (10:10:10) kg NPK/ha. Therefore, this study shows strong correlations, especially between root nodules and grain yield, emphasized key links. NPK doses impacted vital root nodules for nitrogen fixation and suggests dense planting of Pratikshya mung beans with increased NPK fertilizer.
