Effect of Cow Dung Vermicompost Rate on Growth of Snap Bean (Phaseolus vulgaris L.) Varieties at Jimma, South Western Ethiopia

摘要

The objective of this experiment was to determine the response of snap bean varieties to different rates of cow dung vermicompost and their interaction effects. A 34 factorial experiment arranged in a randomized complete block design (RCBD) with three replications was carried out under Lath house condition. Factor one consisted three varieties of snap bean (Plati, Faraday and BC4.4), while Factor two consisted four rates of cow dung vermicompost application rate and 1 recommended rate of NPS (R5). The results revealed that, the main effects of vermicompost rates and snap bean variety showed significant difference (P0.05) for all growth parameters studied except for total leaf chlorophyll content. Accordingly, the interaction effect of vermicompost rate and variety were significant for Plant dry weight. Therefore, taking the findings of the present study in to consideration, it may be tentatively concluded that, the farmers at the Jimma may apply the combination of 45t/ha cow dung vermicompost and Variety BC4.4 would help to improve the growth of Snap bean. However, repeating the same study across season and location at field condition would help to draw sound conclusion and recommendations. Hence, future studies should look in to these factors to develop cow dung vermicompost fertilizer and snap bean varieties recommendation for optimum growth of snap bean in Jimma area.
