Abstract:

Despite its very recent history of cultivation in Ethiopia, snap bean is one of the potential legume crops that contribute to the efforts for the realization of food security in the country and to earn foreign currency. However, the scientific information available with regards agronomy of snap bean especially the response of snap bean to N and P fertilizers for its optimum production at Jimma is very limited. Therefore, a field experiment was conducted at Jimma, Southwestern Ethiopia to study the growth response of snap bean as affected by different rates of N and P fertilizer rates. Five levels of N (0, 41, 82, 123, and 164 kg ha−1) and four levels of P (0, 46, 92 and 138 kg ha−1) were laid down in a randomized complete block design with three replications. N was applied in two equal splits (50% at the time of sowing and 50% during flowering) as urea and the entire dose of P was applied basal as triple super phosphate at sowing. The main effects of N and P fertilizer levels showed significant differences (P ≤ 0.05) for all growth parameters studied. The interaction effects of N by P were significant only for root volume. The optimum total pod yield was obtained by the application of N and P at the rates of 82 N kg and 46 kg P2O5 ha-1, respectively and beyond those rates there is a non-significant yield increment. Thus, the application of N and P at optimum rates (82 N kg and 46 kg P2O5 ha-1) increases the growth and consequently increases the total pod yield of snap bean. However, repeating the experiment for more seasons and similar location would help us draw sound conclusion and recommendations. Hence, future studies should look in to these factors to develop fertilizer recommendation for optimum growth and yield of snap bean in Jimma and similar agro ecology area
