'Kinunonami' is a wheat cultivar that was bred for noodle-making at the Gunma Agricultural Experiment Station. With the aim of improving the crude protein content of the grains, the optimum seeding time, seeding rate, and rate of fertilizer application in this cultivar have been investigated to establish a high-yielding and quality method of cultivation. Seeding can be performed from the beginning of November to around 20 November, since the yield of wheat is not affected by the timing. However, the optimum seeding time is considered to be around 9 November, as early and late seeding results in low protein content and delayed maturation, respectively. Although no significant difference was observed in yield and quality in terms of seeding rate, the rate should be about 6 kg/10 a from the perspective of stable crude protein content in the grains. Because additional fertilization was very effective in increasing the yield and content of crude protein in the grains, cultivation should be performed under a system oriented toward its use. In terms of nitrogen component, the application rates for the basal fertilization and additional fertilization at the internode elongation stage are 5 kg/10 a and 6 kg/10 a, respectively.
