Improvement of malting barley quality Ⅲ. Effects of Location, Harvest Time and Dry Method

Grain quality test to search out the optimum conditions to obtain high quality of malting barley was performed. Thousand grain weight, assortment rate, germinating energy, germinating rate and extract were lower in the barley produced in Korea than that imported from Australia, whereas total nitrogen and crude protein contents were higher in the former. The grain harvested at 40th days after heading date showed about 36% of moisture content, however it could be lowered to below 23.5% with two days of sun dry treatment. Optimum revolution rates of thresher to obtain high quality barley were below 500 rpm at 36% of moisture content, and about 600rpm at 26% of it. The grains being inflicted by rain fall during long period of 20 days in the ripening stage were discolored as well as easily infected by mould, and as the results the malting qualities were highly deteriorated.
