Optimized cultivation methods for high yield and quality were studied for the newly-released malting barley cultivar 'Sachiho Golden'. In field trials for fertilization, sowing density, and sowing date, 'Sachiho Golden' found to be a 'heavy ear weight type' cultivar with 10% higher yield than the standard cultivar 'Mikamo Golden'. Sachiho Golden required higher fertilizer levels to maintain the optimum number of ears. However, very high or low fertilization and high sowing densities increased the percentage of hull-cracked grain. Early sowing decreased plumped kernel percentage and increased the percentage of hull-cracked grain, but late sowing increased the kernel protein content and reduced the malt extract percentage. Sachiho Golden should thus be grown with fertilizer levels at the same or slightly higher levels (N: 6.5-7.5 kg/10a) as Mikamo Golden, with standard sowing density (8.5kg/10a) and sowing date (Nov. 5 to Nov. 20).
