Response of Faba Bean (Vicia Faba L.) to Rhizobium Inoculation Rate at Dodola District, South East Ethiopia

Abstract

The investigation was done to evaluate the effect of Rhizobium leguminosaru vicae (EAL110) inoculation rate on the yield components and yield of Faba bean (Vicia faba L.). The test was performed in randomized complete block design with 3 replications under field condition during 2015 cropping season at Dodola district ketaberenda farmers training center, South Eastern Ethiopia. Treatments were 0,330,580 and 830 g/ha rhizobium inoculation. The collected parameters were plant height, root length, nodule density, number of tillers per plant, number of effective tillers per m², number of pods per plant, number of seeds per pod, nodule density, grain yield and hundred grains weight. Significant effect at (p<0.01) due to rhizobium inoculation rate was observed on plant height, number of tillers per plant, number of effective tillers per m2, of pod per plant and grain yield. But
rhizobium inoculation rate did not show significant effect on root length and number of seeds per pod. Maximum yield (2591.70 kg/ha) was recorded at rhizobium rate of 580g/ha. Thus, it can be recommended for Faba bean growing areas with enhancement of Faba bean production and productivity.
