Relay Cropping Mung Bean by Plant Density and Row Arrangements with Maize on Yield and Yield Components of Component Crops at Jejebicho, Southern Ethiopia

Maize is among the most important cereal crops in Ethiopia. Rely-intercropping of mung bean between maize enable to get grain yield instead sole alone. Field experiment was conducted assess effects relay intercropping at different population density and row arrangements with components component crops, evaluate productivity economic value maize-mung Sankura Wereda Jejebicho research station 2019-2021 main cropping season. Three spatial (1:1, 1:2 1:3) four densities (PD) (25%, 50%, 75% 100%) were intercropped variety ‘Shone’. Each included as a for comparison. Randomized complete block design factorial three replications used. days tasselling, physiological maturity, leaf area, area index, hundred kernel weight, harvest index significantly affected by interaction bean. The highest (8.19 ton/ha) obtained from 100% 1:3 arrangement This may due presence high interspecific competition related plant per plot compared other treatments.
