Effect of Intra and Inter Row Spacing on Yield, Yield Components and Growth Parameter of Hybrid Maize at Mettu, South Western Ethiopia

Abstract

Effect of intra- and inter-row spacing on growth, yield components and grain yield of maize was investigated at Mettu, South Western Ethiopia in 2016, to determine the optimum inter- and intra-row spacing of hybrid maize for maximum yield and yield components. The experimental design was a randomized complete block design in split plot arrangement with three replications. Main plot were inter row spacing of 65cm, 75cm and 85cm. Subplot were intra row spacing of 15cm, 20cm, 25cm, and 30cm. Significant interaction effect of inter- and intra-row spacing was observed for leaf area, but for other traits only the main effect of inter- and intra-row spacing was significant. The highest grain yield (9609.2 and 9618.9kg ha⁻¹) was obtained at 15cm intra row spacing and 65cm inter row spacing respectively, while the lowest (8618.5 and 8808.2 kg ha⁻¹) grain yield was obtained from 30cm intra row spacing and 85cm inter row spacings respectively. In conclusion and recommendation, since this experimental data was one season and location data, the comprehensive recommendation could be drawn by investigating data of more locations over years for this hybrid maize.
