Summary
The present study was carried out to determine the effect of sowing date and plant spacing on pod yield, quality parameters and incidence of major diseases in the field of green bean varieties under humid tropical conditions of Jimma southwestern, Ethiopia. The treatments were five level of spacing (50 cm x 7 cm, 40 cm x 15 cm, 40 cm x 10 cm, 40 cm x 7 cm, 30 cm x 15 cm); four level sowing date (July 3rd, July 18th, August 2nd and August 17th) and two varieties (Melka-1 and Melka-5) in a factorial combination of three factors arranged in randomized complete block design with three replications. Pod yield, quality of green bean (snapping nature, tenderness, straightness and fibreless nature) were significantly affected by the interaction of variety, time of sowing and spacing. The highest total pod yield was obtained due to sowing on the 3rd of July. Highest value of 1.139 and 1.924 due to time of sowing was recorded on quality of green bean in snapping nature and tenderness, respectively at July 3. Similarly, the relative value of variety Melka-1 showed highest (1.780) on quality of green bean (tenderness) as compared to Melka-5 (1.506). Furthermore, the highest (1.566) average value on the straightness of green bean was recorded when the crop grown at 3rd July with spacing of 50 cm x 7 cm. However, the incidence of major diseases (rust, angular leaf spot and floury leaf spot) generally affected by sowing time. The highest (33.78%) and (24.55%) were recorded of angular leaf spot and floury leaf spot, respectively due to sowing date at August 2nd and July 18th. Early sowing of green bean (3rd July), narrow spacing (40 cm x 7 cm) and variety Melka-1 had a potential to increase the yield, quality and less disease incidence green bean under Jimma condition.
