Abstract

Globally, mung beans are grown in tropical and subtropical climates as an essential pulse crop. However, lack of appropriate nutrient management combined with the best responsive varieties is a major problem in enhancing productivity of mung bean. Thus, this field experiment was conducted in Gimbo district, Southwest Ethiopia, during the 2024–2025 rain-fed cropping season to evaluate the response of mung bean varieties to Bradyrhizobium inoculation. The treatments comprised factorial combinations of four improved mung bean varieties (Rasa, Boreda, NVL-1, and Showarobit), two Bradyrhizobium (with and without inoculation). Three replications of a randomized complete block design were used to set up the treatments in a factorial experiment. Analysis of variance revealed that two-way interaction of Bradyrhizobium with varieties significantly affected phenology and yield components of mung bean. The results indicated that the interaction effects of Bradyrhizobium with variety showed significantly (p < 0.05) highest grain yield (2.48 t ha⁻¹) compared to others. According to the partial budget analysis, a high net benefit (Birr 77,700.00) was obtained at inoculation of Bradyrhizobium. Therefore, for optimal mung bean grain yield, the Bradyrhizobium inoculation and the Showarobit variety was recommended under rain-fed conditions at Gimbo district and areas with similar agro-ecological zone. However, further study is needed across different locations and seasons for conclusive recommendation.

Keywords: Bradyrhizobium inoculation, grain yield, improved varieties, mung bean, rain-fed agriculture
