Apposite plant
spacing and date of sowing alongside with variety has paramount
significance in improving the pod yield and yield components of
green bean. The aspire of the experiment was to determine the
proper sowing date, varieties, and optimum plant spacing, and
their combinations for better yield of green beans under Jimma
condition. The treatments were five levels of spacing; four
level of sowing dates and two varieties laid out in Randomized
Complete Block Design with three replications. The analysis of
variance revealed that variety significant differences for total
pod yield, while spacing illustrated a significant difference
for total pod yield, leaf area and number of primary branches.
Date of sowing also showed significant differences in total pod
yield and tap root length. Variety X date of sowing revealed a
significant interactions for days to 50% flowering, leaf area,
plant height, root fresh weight, root volume and number of
primary branches. Variety X spacing showed significant
interactions for days to 50% flowering and tap root length. The
spacing X date of sowing interaction was significant only for
root fresh weight. The highest total pod yield was produced by
green bean sowed on July 3, green bean spaced at 40cmx7cm and
Melka-5 variety. The study results suggested that early July
appears the most appropriate date of sowing and a spacing at 40
cm x 7 cm with a variety of Melak-5 recommended for optimum
yield of green been production at Jimma conditions. |
