Abstract
Haricot bean (Phaseolus vulagris L.) is an annual crop cultivated for food as it has high protein content. The objective of this study was to evaluate yield and yield-related traits of haricot bean varieties at the Dollo University research site. Five released and four local haricot bean varieties were used on 3 × 2 m (6 m2) experimental plots using randomized complete block design with three replications. Data pertaining to agronomic traits and yield performance of each variety were recorded and analyzed using R software version 4.0.5 and Microsoft Excel 2010. One way multivariate analysis showed a significant difference (p <0.05) in thousand seed weight. SAB-632, Local-4 (‘Burree’) and SAB-736 showed higher yield than the other haricot bean varieties. They are also high in all agronomic traits except SAB-736. Thousand seed weight and yield were high and significant with positively correlated to each other. Plant height had a high and significant positive correlation with the number of branches and seeds per plant. Generally, it is possible to say that haricot bean varieties, SAB-632 and Local-4(‘Burree’) are preferable in yield at the Dambi Dollo University research site according to the present findings. Therefore, it is good if these two haricot bean varieties are practised for multiplication at Dambi Dollo Research site and other related agro ecologies.
Highlights
Haricot bean (Phaseolus vulagris L.) is an important source of protein, calories and cash for smallholder farmers (1)
This study evaluated the yield and related traits of haricot bean varieties at the Dambi Dollo University research site
It was investigated that there was no significant difference in plant height
Summary
Haricot bean (Phaseolus vulagris L.) is an important source of protein, calories and cash for smallholder farmers (1). It is a favourable vegetable because of its delicious taste and moderate price, available throughout the year (2). Haricot bean is grown predominantly in low land area (300–1100 m), mainly in the rift valley and some mid highland areas (1400–2000 m). It requires a warm, frost-free climate, but the plant may drop its flowers or pods during excessively hot or rainy weather (2). It cannot tolerate frost or elevations above 3000 m but can grow as annuals in temperate climates
