1. Effects of Legume Break Crops on Yield, Nitrogen Use Efficiency and Economy of Maize Production in Western Oromia, Ethiopia: a Review

Prolonged monocropping of maize lacking appropriate soil fertility management is affecting soil fertility and maize production in Western Oromia. The use of legume break crops improved performance of subsequent maize. The biological N2-fixation of legumes as precursor crops reduced the amount of nitrogen fertilizer applied to maize. Higher mean grain yield of maize was obtained following faba bean without and with rhizobia inoculation than maize after maize. The total nitrogen uptake of different... T.A. Goshu, T.A. Goshu, T.A.
