Effect of Rhizobium Bacteria Inoculation Rate on Yield and Yield Components of Field Pea (Pisum sativum L.) at Awi Zone, Ethiopia

Field peas (Pisum sativum L.) is economically a significant crop in Ethiopia. The yield of field peas in our country has fell due to poor management practices of Bio fertilizer rates usage. Three rates of bio fertilizer (0, 250 and 500g ha-1) were laid out in Randomized Complete Block Design with three replications. Number of nodules per plant, Pod numbers per plant, plant height, and effective nodule number of productive tillers, total biomass yield, grain yield, and straw yield were recorded and significantly affected by bio-fertilizer rate application. The determined or the highest grain yield (2671kg ha-1) was recorded from 250 g ha-1 bio-fertilizer rate. Almost 250g ha-1 bio fertilizer rates were superior for the research area. Nevertheless, more investigation has to be done under different locations and seasons to come up with practical recommendations correlated to the current study.
