Pasture persistence, or the lack of it, especially in new grass cultivars, is worrying dairy farmers.
That's shown up in farmer surveys that Dairy NZ has been doing, mainly in the North Island.
The organisation says 76% of respondents in a survey of more than 450 north Waikato dairy farmers, rated pasture persistence either as a concern or major concern.
Network leader Ian Tarbotton says more than half of the farmers surveyed in the lower North island also rated the poor survivability of pasture as a concern or major concern.
In response, DairyNZ is hosting two field days on pasture persistence in northern Waikato at the end of this month to showcase the latest pasture research and provide farmers with information to help them grow better and hardier pasture.
