Effects of Lower Seed Rates and Seed Class on Seed Multiplication Ratio, Quality and Yield of (Hordium Distichous. L) Malt Barley Under Rain Fed Condition.

The average yield of barley in Ethiopia is lower (2.5 t ha-1), as compared to the genetic yield potential of the released varieties (4.0 t -5.0 t ha-1). This low productivity is due to several constraints such as delivery of small quantity, poor quality and lengthy newly released varieties of early generation seed. The experiment was conducted to determine the effects of seed rate and seed class on seed multiplication ratio, seed yield, and seed quality of malt barley at Debre Birhan from 2019 to 2020. An experiment consisted of a factorial combination of four seed rates (40, 60, 80, and 100) kgha-1 and three seed classes (breeder, pre-basic and basic) laid out in randomized complete block design with three replications. The results revealed that seed rates were significantly different (P
