Pasture persistence: farmer observations and field measurements

Abstract

Information is presented on farmer perceptions and concerns regarding key factors leading to poor persistence of sown pasture species. Forty-seven farmers from four regions viz. Northland (beef, sheep), Waikato (dairy), Taranaki (dairy) and North Canterbury (beef, sheep, deer) were asked for their opinions on the 'keys' to persistence and 'killers' of sown species; i.e., factors leading to a decline in sown species. In all regions, grazing management was perceived to be the most important key to persistence and insect pests the top killer of sown species. Better industry dissemination of existing information and further research on forage herbs and insect pest issues are future requirements. In each region, presence of sown species was also assessed in 30 paddocks belonging to the surveyed farmers. There was a significant decline in pasture chicory presence, but no decline in that of cocksfoot or plantain. Ryegrass, white clover and tall fescue were present in nearly all paddocks in which they were sown. Chicory may be best used as a crop, while plantain shows greater potential for persistence as part of a pasture mix. Keywords: chicory; farmer survey; information gaps; plantain; research needs
