Abstract
BackgroundThe study was conducted in 2017 main cropping season at two locations in North Gondar Zone, Ethiopia, to determine the optimum inter- and intra-row spacing of mung bean for maximum yield and yield components. The experiment was laid in a randomized complete block design with three replications in a factorial arrangement of four inter-row (20, 30, 40 and 50 cm) and three intra-row (5, 10 and 15 cm) spacing using mung bean variety Rasa (N-26).ResultsSignificant interaction effect of inter- and intra-row spacing was observed for days to maturity, number of branches per plant, number of pods per plant, grain yield, harvest index, days to flowering, plant height and aboveground dry biomass yield. The highest grain yield (1882.67 kg ha−1) was obtained at interaction of 40 × 10 cm spacing, while the lowest (1367.8 kg ha−1) was obtained from 20 × 5 cm spacing. However, the result of economic analysis showed that the maximum net benefit was obtained at spacing of 40 × 15 cm.ConclusionsBased on agronomic performance and economic analysis, use of 40 × 15 cm is promising for mung bean production in Metema District and similar agroecologies.

Summary
The study was conducted in 2017 main cropping season at two locations in North Gondar Zone, Ethiopia, to determine the optimum inter- and intra-row spacing of mung bean for maximum yield and yield components. Mung bean (Vigna radiata L.) is one of the most important pulse crops, grown from tropical to subtropical areas around the world [1]. It is an important wide-spreading, herbaceous and annual legume pulse crop cultivated mostly by traditional farmers [2]. In Ethiopia, mung bean covers about 27,086 ha of land and produces 241,589.90 tons in main cropping season per annum with average productivity of 0.9 ton ha−1 [12]
