General Information

Paspalum dilatatum is a clump-forming, perennial grass with clustered stems arising from very short, creeping rhizomes. The stems are erect to ascending, growing 30 - 180cm tall and producing new roots at the nodes when in contact with the soil. The roots can descend as much as 120cm into the soil[

Cultivation Details

Paspalum dilatatum grows best in the subtropical zone in regions without a dry season, or with only one or two monhs without rain. It is often cultivated and can succeed from the tropics to the warmer parts of the temperate zone; it can be found at elevations up to 2,300 metres. It grows best in areas where annual daytime temperatures are within the range 20 - 30°c, but can tolerate 13 - 36°c[

Vegetative spread is extremely slow. Although a slow establisher and with the impediment of disease of the inflorescence, it has been a remarkably successful coloniser[

Established plants have their fastest growth rate early in the growing season, but growth slows down during mid-summer and autumn. During the cool period in subtropical regions and at higher altitudes the plants are dormant. Flowering occurs throughout the growing period and seeds scatter as soon as they are ripe. With declining soil fertility, the vigour of the plant declines and it is then often invaded by other species[

Paspalum dilatatum can be divided into two varieties, var. Dilatatum and var. Pauciciliatum Parodi. The latter has 2n = 40 chromosomes and is more prostrate. It has slightly smaller and less hairy spikelets, more spikelets per raceme and its lemma and palea have three veins compared with nine in var. Dilatatum. This variety is better adapted to light and poorly drained soils than common Dallis grass. Important cultivars of var. Dilatatum are 'Raki' from New Zealand, 'Charu' from Uruguay and 'Natsugumo' from Japan[

]. It can be sown at any time from spring to late summer, although best sown just before the expected rainy season since germination and establishment can be slow. While seed is generally drilled or broadcast into a well-prepared, fine, weed-free seedbed, it can also be sown directly into rice stubble without further seedbed preparation. It is normally sown at 5 - 10 kg/ha, and preferably placed less than 15mm deep[
