Offered Papers Theme A: Efficient Production from Grassland
Description
In dryland areas of the IX Region of Chile, with a dry period of 150 days with a negative hydrologic balance beef production is based on natural pasture, with low P soils, which produces a low DM yield. The sown pasture for this area is fescue in mixture with subclover. The subclover, has persistence problems and erratic production (Romero & Rojas, 2001). Hard seeded serradella (Ornithophus compressus), soft seeded serradella (O.sativus) and biserrula (Biserrula pelecinus) are annual forage legumes and well adapted to low P levels in the soil (Oram, 1990). The objectives of the present study were to evaluate the 3 legumes species and different cultivars in terms of dry matter (DM) yield and the ability to form seed banks to improve the persistence of the legumes in a ley farming system for beef production.
