Many research works done on behalf of malt barley fertilizer rate and time of application. But, there is no enough information on the association of its grain yield and quality parameters of malt barley. Therefore, a field experiment was conducted during main cropping season of 2018/2019 at West Arsi zone of Ethiopia with the objective of Pearson correlation analysis of grain yield and malt quality parameters under varied varieties and nitrogen application time at Arsi Zone of Ethiopia. Factorial combination of two malt barley (Ibon 174 and Traveller) varieties and three times of nitrogen application 100% recommended rate of N fertilizer ha-1 at planting (150 kg ha-1 ), 1/3 at planting and 2/3 at tillering, and 2/3 at planting and 1/3 at tillering) laid out in randomized complete block design with three replications. The result reveals that grain yield was positively correlated with hectoliter weight, thouthend kernel weight, sieve test, protein content and germination energy, while extract content and germination capacity was negatively associated

Keywords : Grain Quality, Grain Yield, N Application Time, Varieties.
