Resumen

OVALLE M., Carlos et al. Attributes and behavioral background of Biserrula pelecinus L. a new annual forage legume for Mediterranean Chile. Agric. Téc. [online]. 2004, vol.64, n.1, pp.74-81. ISSN 0365-2807.  http://dx.doi.org/10.4067/S0365-28072004000100009.

In Chile Biserrula pelecinus L. is a new legume forage species for acidi soils, with medium - light texture, in dryland areas of the humid and sub-humid Mediterranean zone. Due to its high rate of hardseedness (99% at the beginning of the second growth season), it is an especially appropriate annual pasture for agricultural systems where the pasture is in rotation with cereals ('ley farming system'). It is an intermediate maturing plant (132 to 136 days to flowering), with a semi-erect growth habit, blue flowers, small seed size (674 to 842 seeds g-1), and has a high index of reproductive force (superior to 1.6). The DM and seed production is comparable, and in some years superior, to that of species traditionally used in these areas, such as subterranean clover (Trifolium subterraneum L.) and burr medic (Medicago polymorpha L.). However, its productivity in the second year of growth is very low due to the high percentage of hardseedness (99%). Currently, there is cv. Casbah , developed by a team of researchers of the Center for Legumes in Mediterranean Agriculture (CLIMA), Western Australia. The phenological background and phytomass productive behavior permit its recommendation in areas of the interior and coastal dryland of the 7th and 8th region o Chile.

Palabras clave : forage legume; Biserrula pelicinus; Mediterranean climate.
