【 摘 要 】

Studies were conducted to stabilize the high yield and quality of malting barley in Nasu where grain crude protein content is high. The incidence of barley yellow mosaic virus (BaYMV) was as high as 63.0% (70.5% when, resistant cultivars were excluded) in Nasu district. Then the use of BaYMV-resistant cultivars such as ‘Sukai Golden’is necessary for stable production and high quality. Analysis of the cultivation history revealed that grain crude protein content had a significant positive correlation with sowing time, and harvest time, and a significant negative correlation with the application phosphate fertilizer. The yield was increased by applying levels of alkali fertilizer, and treading barley plants just before the jointing stage. However, such operations are performed by only a half of the farmers, resulting in a large variation in protein content and yield, and also in a high protein content of grain that is not suitable for malting barley. For improvement of protein content and stabilization of high yield sowing at a suitable time and improving soil by application of phosphate and alkali fertilizers are necessary.
