RESUMEN. - La lechería en Uruguay representa un componente esencial, tanto desde lo económico como en lo cultural. Dentro de los datos de interés podemos mencionar que el 70% de lo que producimos se exporta, que somos el país de Latinoamérica con mayor consumo per capita de leche y sus derivados; y nos encontramos entre los primeros 12 países cuyas exportaciones de leche y derivados alcanzaron los valores más elevados durante el
ABSTRACT.- This study evaluates nutritional and management strategies aimed at exploiting compensatory growth (CG) in weanling-to-beef systems in Uruguay. The evaluation encompassed productivity, economic viability, and environmental impact. The Grange Beef System Model, augmented with Uruguayan national technical coefficients, was used.
Los sistemas arroz-ganadería disminuyen en forma significativa el área de pastoreo durante el verano debido a la presencia de los cultivos (arroz y soja) y a la realización de laboreos de verano para la próxima zafra de arroz. Esta situación se agrava a medida que el área de la rotación ocupa un porcentaje mayor del área total del sistema y que aumenta la intensidad agrícola de la rotación.
ABSTRACT. - Olive anthracnose caused by Colletotrichum spp. is the most important olive fruit disease worldwide. We hypothesize that induced water deficit in olive trees generates anatomical and biochemical changes which contribute to anthracnose fruit rot resistance. A three-year experiment was conducted in Arbequina under two irrigation treatments: fully irrigated (no water stress) and non-irrigated (moderate water stress), from pit hardening until harvest. At harvest, fruits were inoculated both in planta and in vitro with an isolate of C. acutatum s.l.
ABSTRACT. - Studies of oriental fruit moth (OFM), Grapholita molesta (Busck), and codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), both important pests of pome fruit, evaluated the addition of low-intensity light-emitting diode (LED) to delta traps baited with 3 commercial monitoring lures. Studies were conducted in 9 orchards treated with and without sex pheromone mating disruption for one or both species.
