Response of Varieties, Nitrogen and Seeding Rate on Grain Yield and Malt Quality Parameters of Malt Barley (Hordeum vulgare L.) in the Central Highlands of Ethiopia

Abstract

Identifying optimum seeding and Nitrogen rate for crop varieties is an important agronomic practice to improve the productivity and the quality of the produces. Therefore, this study was conducted to evaluate the effect of variety, Nitrogen and seeding rate on protein content and yield performance of malt barley under rain-fed conditions at wolmera district, west shoa, Ethiopia for three years (2016-2018). The experiment was arranged in a split-split plot design with two malt barely varieties (Beka and traveller) as main plots, factorial combination of four N fertilizer levels (0, 23, 46, and 69 kg ha^-1) and five seeding rates (75, 100, 125, 150. 175 kg ha^-1) as subplots, with three replications. The three year combined results indicated that malt barley varieties tasted were significantly different in grain yield, biomass yield, kernel weight and malt extract. But there is no significant difference on protein content of varieties. Nitrogen rate significantly affect grain yield. biomass yield, protein content and malt extract of malt barley. But kernel weight is not significantly altered by nitrogen rate. Effect of seed rate was not significant to alter grain yield , biomass yield, protein content and malt extract. Only kernel weight was significantly affected by malt barley seed rate. Interaction effect of varietie , nitrogen rate and seed rate was not significant to affect any of parameters tasted in the study. According to this study, Application of 100 kg ha^-1 seeding rate with 46 kg N ha^-1 can be preferable for farmers  for maximum benefit in terms of grain and  quality parameters of malt barley production on Nitisols of West Shoa under rain fed conditions for both varieties.
