Abstract
Average yield of wheat and barley cultivars has been increased 3 percent every year by varietal improvement. The major characteristic changes of those improved cultivars were the early maturing and lodging resistance using dwarf genes, 70-90cm of culm length appearances, under the heavy fertilizer application. Looking back the cultural practices of wheat and barley for the last 20 years, the introduction of early maturing and lodging resistance cultivars around 1970 brought the changes of seeding rate from 65kg to 130- 200kg per hector and the tillering increased by heavy fertilizer. The utilization of livestock and man power for preparation of seedbed were gradually disappeared by increasing agricultural mechanization. The narrow-spaced seeding
