Abstract | The southern dairy regions of Australia are heavily reliant on pasture growth throughout the year to maintain long lactation lengths in dairy cows. However, seasonal growth patterns and poor production of pasture during long dry summers limit milk production. As a result there has been an increased focus on the use of summer forage species to better utilise available irrigation water. A preliminary field study was undertaken in northwestern Tasmania examining potential dry mater production of tropical forage species. Eight tropical forages: Japanese millet (Echinochloa utilis cv. Shirohie and cv. Japanese), white panicum (E. frumentacea cv. Siberian), sorghum x sudan hybrid (Sorghum sudanese cv. Pacific BMR, cv. Sweet Jumbo, cv. Pac F8386, cv. Bettagraze) and hybrid pennisetum millet (Pennisetum glaucum cv. Nutrifeed) were sown at six planting dates between 1st December 2005 and 8th January 2006. There was discernible variation in yield between species and between cultivars within species. Sorghum x sudan hybrid cv. Bettagraze displayed the greatest yield potential, yielding 16 t DM/ha over 14 weeks from a single harvest. The highest level of cold tolerance and regrowth potential was displayed by Japanese millet cv. Shirohie, while white panicum cv. Siberian was found to be susceptible to low temperatures, resulting in slow seedling establishment and low yields. |
