Influence of Inter and Intra Row Spacing for Growth and Yield of Maize

Effect of inter row and intra row spacing on growth, growth parameters, yield and yield related parameters of maize was studied at Melkasa Agricultural Research Center, Ethiopia during the rainy season in 2019 and 2020. The objective of this study was to evaluate impact of inter row and intra row spacing on growth and yields of maize variety Melkassa-II. The experiment was laid out in randomized complete block design with a split-plot treatment structure of 4 inter spacing levels as the main plot and 3 intra row spacing levels as sub plot factors. There was significant (P<0.05) main effect of inter row spacing, and interaction of inter row and intra row spacing on leaf leaf area index, cob weight, grain yield, 1000 seed weight and harvest index. There was also significance difference due to the main effects of inter row spacing on leaf leaf area index, cob weight, plant height, kernels per row, above ground biomass, grain yield, 1000 seed weight and harvest index. Higher grain yield and above ground dry biomass yield were due to intermediate and closer spacing. By considering other crop management factors it can be concluded that spacing combination of 65 cm * 20 cm can be recommended in attaining higher grain yield of Melkassa-II maize variety in similar environment.
