Abstract:

Maize (zea mays L) is one of the most important cereal crops grown in Ethiopia. Field experiment was undertaken on clay loam soil at Teppi national spice research center, Ethiopia during 2013/2014 cropping season with the objectives of investigating the effect of supplementary irrigation on yield and yield component of maize for achieving maximum crop yield in rain fed agriculture during belge season. The experiment was laid out in RCBD (Randomized Complete Block Design) with three replications. Treatments include seven levels of supplemental irrigation treatments and a control irrigation receiving no supplemental irrigation. The irrigation water was applied when the soil moisture depleted reached 55% of total available water (p=0.55). The supplemental irrigation levels had shown a highly significant (p
