Abstract

Field experiments were carried out in 2016 and 2017 cropping seasons under on-farm conditions in Lemuna Bilbilo District, Southeastern Ethiopia to evaluate the effects of three varieties Degaga, Gora, Moti, and six plant populations (10, 25 (control), 30,50, 70, and 90 plants m-2) on faba bean specific yield and yield components. The experiments were laid out in a randomized complete block design in split plot arrangement in which varieties were assigned to main plots and plant populations to subplots with three replications. The year combined analysis of data revealed that seed yield, total biomass yield and test weight of seed were significantly (p<0.05) affected by varieties and plant population densities m-2. The highest seed yield (4649, 4594 and 4162 kg ha-1) was obtained at 90,70 and 50 plant m-2 for Degaga, Moti and Gora varieties respectively but, no significant difference between control for Degaga and Moti varieties. The highest total biomass of 9 t ha-1 was recorded from the highest 90 plant population m-2 though not significantly different to the total biomass obtained from 70, 50 and 25 (control) plants m-2. Gora variety significantly recorded the highest test weight of seed (889.2g) than the rest Degaga and Moti varieties. In short, founded on studied agronomic parameters of faba bean, 25 plant population density m-2 was economically recommended for Degaga and Moti varieties whereas, 50 plant population density m-2 was for Gora variety.
