  • Ryegrass goes through some changes at this time of year. How you manage these effects the quality and quantity of feed for the rest of the season. During October you will start to see stem elongation as the growing points turn reproductive and a seed head will appear in the coming weeks. As seed heads grow: Pasture growth rates increase - the stems contain a lot of dry matter. Growing points stop producing new leaves, but existing leaves live longer. The quality of the pasture falls - stems are less digestible than leaves.

    Keeping a consistent post grazing residual around 1,500 -1600  kgDM/ha will minimise the pasture quality drop. Mowing maybe needed to reset high residuals.

    The second change is the development of daughter tillers. These are already appearing and will replace the reproductive tillers (which will die), producing feed for next year. To help these new tillers survive they need sunlight and nutrients. Avoiding high pre-graze covers and heavy silage crops gives them the best chance of survival and thicker pasture.
