The growth of 2 species of warm-season grass was compared with that of summer weed. Grass species used were bahia grass, Paspalum notatum Flügge, and bermuda grass, Cynodon dactylon Persoon. As a summer weed, large-crab grass, Digitalia adscendens Henr. was used.They were sown in a plastic pot late in May, early in July and late in September, 1978, then grown under natural conditions. Results were summarized as follows. 1.Emergence of large-crab grass required the least number of days from seeding, and grew vigorously at any time, when compared with those of warm-season grasses. Particularly large-crab grass seeded in July grew most rapidly. 2. The most vigorous growth of bahia and bermuda grass was also observed when seeded in July. An interesting tendency was seen: the earlier the seeding time in bermuda grass and the later in bahia grass, the larger is the ratio of their dry weight to that of large-crab grass. It can be concluded that the proper time of seeding is in May for both grasses, considering the competition with the growth of summer weed ; bahia grass, however, grew well if sown in September. 3. Since the bermuda grass showed a great variation in the dry weight with the seeding time, it can be said that the growth of this grass is affected strongly by seeding time. 4. It can be concluded that bermuda grass is one of the most suitable grass species to be sown for a pasture establishment without tillage, because of its rapid elongation of stolons, which quickly cover the ground.}, pages = {115--121}, title = {暖地型牧草ならびに強雑草メヒシバの初期生長について}, volume = {63}, year = {1981} }
