Arrowleaf Clover (Trifolium vesiculosum Savi): A New Species of Annual Legumes for High Rainfall Areas of the Mediterranean Climate Zone of Chile Chilean J. Agric. Res.
Ovalle M,Carlos; del Pozo,Alejandro; Fernández,Fernando; Chavarría,Jorge; Arredondo,Susana.
The present review examines the main attributes and agronomic characteristics of arrowleaf clover (Trifolium vesiculosum Savi) and its incorporation into production systems in dryland areas of the Andean foothills of the humid Mediterranean climate zone of Chile. It is a new species of annual legume in Chile for light and medium textured soils. The root system can reach a depth of 1.5 m and its seeds have a high percentage of hardseedness (99.8%). It is an upright plant, with purplish-white flowers. The mature plant has large arrow-shaped leaves up to 50 mm long, often marked with a large white “V”. Dry matter and seed production in the Andean foothills is high (3.9-8.8 t DM ha-1 and 700-900 kg ha-1, respectively), surpassing the productivity of sub clover...

Biological Fixation of N2 in Mono and Polyspecific Legume Pasture in the Humid Mediterranean Zone of Chile Chilean J. Agric. Res.
Espinoza,Soledad; Ovalle,Carlos; del Pozo,Alejandro; Zagal,Erik; Urquiaga,Segundo.
Despite annual legume pasture are of great importance for dryland agricultural systems in Mediterranean environments, there are few studies of N2 biological fixation (NBF) reported in Chile. In this study the NBF of four annual legume species: subterranean clover (Trifolium subterraneum L.), yellow serradella (Ornithopus compressus L.), arrow-leaf clover (T. vesiculosum L.), and crimson clover (T. incarnatum L.) (Experiment 1), as well as seven mixtures of these species (Experiment 2) were assessed. The NBF was measured by the 15N natural abundance technique. The objective was to determine NBF in the legume species and in distinct mixtures used. The study was carried out in an Andisol of the Andean Precordillera located in the humid Mediterranean zone of...

Lucerne and other perennial legumes provide new options for rain fed livestock production in the Mediterranean-climate region of Chile Ciencia e Investigación Agraria
Ovalle,Carlos; Espinoza,Soledad; Barahona,Viviana; Gerding,Macarena; Humphries,Alan; del Pozo,Alejandro.
In dryland Mediterranean environments, the productivity of annual legumes is low during autumn and winter, with plant senescence typically beginning by the middle of spring because of low soil water availability. Therefore, the use of deep-rooted perennial legumes may provide an alternative to annual legumes in regions with a soil moisture déficit. We evaluated the germplasm of new perennial legumes with deep rooting systems in two field experiments in the interior drylands of central Chile. In experiment 1, sixteen genotypes of four perennial legume species, nine cultivars (cvs.) of Medicago sativa, two of Hedysarum coronarium, three of Lotus tenuis, and two of Lotus corniculatus were evaluated for three seasons (2012-2014). In experiment 2, eight...
