Summary
editDescriptionSetaria incrassata spikelets11 NWP - Flickr - Macleay Grass Man.jpg | Introduced warm-season perennial large tufted C4 grass; stems usually have hairy nodes, grow 30-200 cm tall and arise from short rhizomes. Leaf bases may be hairy and blades are 10-60 cm long and 3-14 mm wide. Flowerheads are narrow cylindrical bristly spike-like panicles to 18 cm long. Spikelets are 2-flowered and are surrounded by uniformly coloured bristles that remain after the spikelets fall; the upper glume is 40-55% of the spikelet's length. Flowers from early summer to autumn. A native of Africa, it occurs is sown as a pasture species, especially on medium to heavy soils of high fertility; it has also become naturalised on the North West Slopes and Plains. Easy to establish on heavy clays and is tolerant of drought and temporary waterlogging. Has superior production to most other tropical grasses in its first and second year after establishment. Oxalates may affect horses and cattle. Has reasonable palatability and feed quality below about 40 cm in height, but quickly runs to head and is then avoided by stock; generally preferred by cattle rather than sheep. Graze frequently to maintain quality. Heavy grazing in late summer promotes autumn germination of winter annual legumes; however its abundance will decline under heavy continuous grazing. Sufficient soil nitrogen is essential for its persistence. |
