Description

In 1973-1977, the response of yield and quality as silage materials on two planting density were investigated in early, medium, and late maturing varieties at Memuro in the central part, Shintoku in the piedmont, and Churui in the coastal part in north-eastern areas of Hokkaido. The results obtained were as follows: 1. In central parts dry matter or TDN yield of early varieties increased by about 30% in dense planting, and was as high as other maturing groups. 2. There were no differences between two planting densities for dry matter contents as an indicator of the quality of silage materials in early and medium maturing varieties, but TDN in dry matter of late variety groups decreased a little in dense planting. 3. The high rate of barren plants and nubbin ear plants by dense planting could observed in late maturing varieties than others, and those rates were augmented by the increase of lodging. 4. Improvement in adaptability to high planting density and in lodging resistance of early and medium maturing varieties are seemed effective in corn breeding for high yielding-good quality varieties.
