Effects of Varieties and Intra Row Spacing on Yield of Maize (Zea mays L.) under Supplementary Irrigation at Guliso, Western Ethiopia

Abstract

Determination of optimum plant population and the use of improved varieties in combination with appropriate agronomic practices are important components of maize production package for maximizing productivity. The study was conducted 2017-2018 under supplementary irrigation at Gulliso district, Western Ethiopia, to determining the effects of variety and intra-row spacing on yield of maize (Zea mays L.). The experiment was conducted in factorial arrangement of four intra-row spacing (20, 25, 30 and 35cm) with three maize varieties (BH546, Shone and BHQPY-545) in RCBD. The interaction of variety and intra-row spacing was highly significant (P
