Effects of Plant Density on the Yield Components of Haricot Bean (Phoseolus vulgaris L.)

Abstract

Haricot bean (phoseolus vulgaris L.) is among the five pulse crops predominantly grown in Ethiopia. The experiment was conducted to determine the effect of plant density on yield components of haricot bean in randomized complete block design with three replications. The Data collected for Plant height, Number of branches per plant, Number of leaves per plant and Stem thickness were analyzed using analysis of variance (ANOVA). The analysis of variance showed significantly (p?0.05) different for number of branches per plant, number of leaves per plant and stem thickness whereas non significant (p?0.05) different for plant height. The second plot with below the recommended density or twelve (12) plants per plot was contain large stem thickness, shorter plant height, more broad and dark green leaf as compared to treatment one and three whereas the third plot with above the recommended density or sixty (60) plant per plot was contain small stem thickness, longer plant height, small leaf number and medium number of branches as compared to others.

Key words: analyzed using analysis of variance, Density, phoseolus vulgaris, randomized complete block design, yield components
