EFFECTS OF METHOD OF RHIZOBIUM INOCULATION AND PHOSPHORUS RATES ON NODULATION, YIELD COMPONENTS AND YIELD OF FABA BEAN (Vicia faba L.) AT HARAMAYA, EASTERN ETHIOPIA

Abstract:

Haramaya University main campus, Eastern Ethiopia, with the objectives of evaluating the effect of methods of Rhizobium inoculation and phosphorus (P) rates on nodulation, yield components and yield of faba bean and to identify economically beneficial treatment (s) for higher yield of faba bean. Factorial combinations of five P levels (0, 23, 46, 69, 92 kg P2O5 ha-1) and four levels of Rhizobium inoculation methods (uninoculated, seed inoculated, soil inoculated, seed + soil inoculated) were laid out in a Randomized Complete Block Design with three replications. Interaction of Rhizobium inoculation method (RIM) and P rates significantly (P
