To demonstrate establishment and productivity of leucaena in selected areas of the Darling Downs

Summary

Real interest in growing Leucaena in southern Queensland for cattle grazing dates back to 2000 where an 8 ha patch was grown in Chinchilla. Others followed and by 2005, it was considered important to test the viability and suitability Leucaena as a pasture legume for the Darling Downs.
In this project, four sites representing a range of soil types, farming techniques and row spacings were established successfully and have grown on to become very productive paddocks of forage.
Leucaena has shown itself to be a viable option for this part of southern Queensland. It provided the reliable legume for pasture mixtures that has been missing. However, it may not be suitable for everyone, particularly those who are intent on breeding their own calves and selling weaners or yearlings.
The immediate effects are that farmers in the relevant parts of the Darling Downs can plan, with confidence, on returning marginal cropping land back to a very productive mixed pasture. Following the established guidelines is highly recommended and seeking expert advice will maximise the expected outcomes. It is recognised that further work would be beneficial and strengthen the position of Leucaena in the farming system in the areas of longer term viability and production, grazing methods, optimal row spacings and inter-row planting opportunists
Leucaena is the best summer growing legume option available. The presence of a legume gives the pasture system that much needed boost to productivity and sustainability.
