Description
Eastern Hokkaido is located in the southern end of the subfrigid zone. It has a very cold winter, although the summer is reasonably warm and humid. The annual temperature ranges between -25 °C and 30 °C, averaging about 7 °C in Obihiro. The precipitation averages about 900 mm per year. Soil freezing is very common in this area. Therefore, there is general agreement among workers that forage seeding in eastern Hokkaido must be confined to spring or summer. But the success of seeding is highly dependent upon the moisture content of the soil. For example, in some years in eastern Hokkaido, grassland cannot be successfully established due to drought damage by ,< Tokachiharukaze >> a local name for special winds in the Tokachi Plain experienced during spring time. Hence we were very interested in studying the effect oflate fall (dormant) seeding (commonly practised in Canada) that ensures germination early in the following spring, so that young seedlings can take advantage of moisture from the winter snowfalls. The objective of this study was to determine the effect of seeding date on the establishment and survival of forage grasses and legumes as compared to traditional spring sown plots, and to compare the early growth of two grass species that were sown in early winter and spring (Anderson and Elliot, 1957; Brooke and Holl, 1988).
