Series: Agnote DPI-308 Edition: Second edition Last updated: % asset_metadata_Display.date%
|Pasture type and use||Short-lived perennial tropical legume, growing in the warm season. Main production is in summer. Grazing, but has been used for hay and silage.|
|Area of adaptation||Far North Coast, North West Slopes.|
|Min. average annual rainfall||Far North Coast: 800–1000 mm.
North West Slopes: 650–700 mm.
|Soil requirements||Light-textured well-drained soils. Not suited to hard-setting soils.|
|Sowing time||A high level of hard seed allows sowing between September and early March.|
|Companion species||Compatible in mixtures with adapted species.|
|Major nutrient deficiencies||Phosphorus, potassium, sulfur and molybdenum.|
|Main insect pests||Relatively free from pests.|
|Main diseases||Relatively free from disease.|
|Management||In first season, allow seed-set for future plant recruitment, as plants die after about 16–18 months. Hard short-duration grazing suits Wynn. Do not allow selective continuous heavy grazing, which can lead to Wynn cassia dominance.|
|Livestock disorders of particular note||Some cassia spp. (e.g. C. obtusifolia and C. occidentalis) have been associated with poisoning in ruminants and horses — both leaves and seeds were toxic, and muscle damage was the main effect. So far there have been no problems reported for C. rotundifolia.|
