Growing/Caring conditions

• Puccinellia seed ought to be sown in gently cultivated soil which has excellent weed control right after the break in season.
• Sowing rates are between 6 – 10kg/ha.
• More saline the ground is, the dense the bed of seed ought to be i .e., the higher the percentage of seed employed.
• When sowing on clean scalds, seed is generally sown without turning round later on.
• Results to date demonstrate puccinellia does respond well to nitrogen-based fertilizer.
• The ideal response is from an autumn/winter practical application (i.e., applied shortly after the seasonal break).
• This strategy is good in supplying the space such that it does not get waterlogged within four weeks of use of urea.
• Plant appearance might take as much as two months.
• Make sure absolutely no grazing takes place in the initial ten to twelve months, enabling the stands to originate properly.
• Most important is the fact that Puccinellia is not greatly grazed for lengthy duration.
• Puccinellia most likely will turn out to be invasive in non-agricultural regions.
• To avoid this danger it is strongly recommended that sowing must enable buffer zones besides these ‘at risk’ areas.

The following buffer ranges for public and also local vegetation areas is suggested:
– 100 metres from saline areas
– 50 metres from poorly drained areas
– 50 metres from waterways
– 25 metres from other non-agricultural areas

Pests
• The red legged earth mite is known to damage the most damage in the establishment period.
• It is a pest that has to be monitored and controlled.
