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...

Production and economic viability of banana managed with cover crops AGRIAMBI
Barbosa,Francisca E. L.; Lacerda,Claudivan F. de; Amorim,Aiala V.; Costa,Raimundo N. T.; Silva,José A. da; Hernandez,Fernando F. F..
ABSTRACT This research aimed to evaluate the yield and economic viability of three crop cycles of the banana cv. ‘Prata Anã’ in association with perennial herbaceous legumes, natural vegetation, or compared with the conventional management. The research was conducted using a complete randomized block design with split-split plots and four replicates. The plots were formed by four irrigation depths: 50, 75, 100 and 125% of crop evapotranspiration, and the subplots by cover crops (Calopogonium muconoides, Pueraria phaseoloides, and natural cover without N addition) or no cover crops with addition of N fertilization (conventional management). The subsubplots were formed by the second, third and fourth banana production cycles. Yield and economic viability of...
