Abstract

The experiment was conducted in 2016/17 cropping season under rain fed condition in Metema and Tach Armachiho districts of the Amhara regional state, Ethiopia. The treatments consisted of a factorial combination of four levels of inter row spacing (40, 60, 80, 100 cm) and three levels of intra row spacing (5, 10, 15cm). The treatments were laid out in randomized complete block design with three replications. The main effects of row and intra row spacings were significantly affecting days to 90% physiological maturity, number of branch/plants, biomass yield and grain yield/hectare. On the other hand, except harvesting index, all other parameters were not significantly influenced by the interaction effect of inter and intra row spacing. The highest biomass and grain yields were recorded at 40cm inter and 5 cm intra row spacing. Results of the economic analysis showed that the maximum net benefit was obtained in soybeans planted with 60 cm by 10 cm inter and intra row spacing, respectively. Thus, farmers in Metema and Tach Armachiho can use 60cm by 10cm inter and intra row spacing respectively for mung bean production.
