Notes
Two field experiments were carried out to discuss the growth, development, yield and some forage constituents of five tropical and subtropical grass species in relation to the air temperature condition. At the high temperature condition, these grasses emerged early and showed the accelerated growth rate, the advanced growth stage, and accordingly the deterioration in the forage quality. The optimum seeding period was considered to be at the mean daily temperature of 16-18℃ (from late April to late May in Fukuoka district) and three times cutting until autumn was suitable for forage production. Green panic (Gp), the lowest in winter survival, produced the highest total dry matter, conversely, dallisgrass (Dg) and Bambatsi makarikarigrass (Bp), the highest in winter survival, were low in dry matter production. The wintering ability and the production of Kazungula setaria (Ks) and Gayndah Buffel grass (Bg) were intermediate between Gp and Dg or Bp. Dg and Bg was excellent in the forage quality and the latter was superior in the potentiality at a low temperature.
5草種の暖地型イネ科牧草の生育,収量および成分を気温との関係で検討するために2つの圃場試験を行なつた.供試草種はいずれも高温下で,出芽が早く,その後の生長も旺盛で,生育ステージの進行が速い.同時に草質の低下も生じる.播種適期は,日平均気温16～18℃ のころ(当地方で4月下旬～5月下旬)で,秋までに3回刈りするのが適当と考えられる.greenpanic(Gp)は越冬性が劣るが,乾物の生産性が高く,逆に越冬性の高いdallisgrass(Dg), Bambatsimakar童karigrass(Bp)は,生産性が低い.Kazungulasetaria(Ks),GayndahBuffelgrass(Bg)はこれらの中間的位置にある.Dgは草質に優れ,Bgは草質と低温生長性に優れている.
