Resumen:La roya de la hoja de trigo (RH), causada por Puccinia triticina Ericks, es una de las enfermedades del cultivo más prevalentes en Uruguay y otros países del Cono Sur. En epidemias severas se han estimado pérdidas de rendimiento de más de 50 % y pueden ser necesarias dos o más aplicaciones de fungicidas para controlar la enfermedad en cultivares susceptibles.

ABSTRACT. Some entomopathogenic fungi such as Metarhizium and Beauveria not only have the ability to infect and kill insects but also the capability to associate with plant roots. The potential benefits from this plant-fungus association include nutrient acquisition, plant growth promotion and protection against stressors. The objective of this study was to evaluate the delivery of entomopathogenic fungi in seed coating to determine whether the fungal presence affected maize performance.

Resumen:La producción estacional de forraje de pasturas está determinada por las condiciones climáticas. La temperatura del aire, la radiación solar y la disponibilidad de agua en el suelo son las principales variables que afectan el crecimiento de la alfalfa. En este trabajo se analizó la relación entre el crecimiento de la alfalfa (Medicago sativa L.) y algunas variables climáticas usando 15 años (1997-2011) de datos productivos y climáticos recolectados en el suroeste de Uruguay.

ABSTRACT. Natural grasslands are being progressively degraded around the world due to human-induced action (e.g., overgrazing), but there is neither a widely accepted conceptual framework to approach degradation studies nor a clear definition of what ?grassland degradation? is. Most of the drivers, processes, and consequences related to grassland degradation are widespread and are usually separately quoted in the literature.

Abstract:Soils are a key issue in the management of global environmental changes and food supply. The goal of this work was to characterize the soil changes that were promoted by agriculture in Uruguay in the period 2002?2014. We analysed the association between pH, Ca2?, Mg 2?,K ?, Na ? and soil organic carbon (SOC) and its tendency through the years of soil analysis database 2002?2014 that belong to Experimental Station Alberto Boerger INIA La Estanzuela (Colonia, Uruguay).

Abstract:Increasing the provision of non- fibrou s carbohydrate s (NFC) during the prepartum period is a feeding strategy that has been recommended to facilitate the transition to the onset of lactation and improve dairy cow performance, but results ar e contradictory, probably because most studies have confounded the effect s of level and source of energy. The objective of this experiment was to evaluate the effect of the source of carbohydrate offered in the prepartum diet on postpartum cow performance.

ABSTRACT. Gala Fult is the first Uruguayan apple cultivar, originated by spontaneous somatic mutation of ?Royal Gala?, identified and evaluated by nurseryman Fernando Rocca and INASE. The fruits have a complete red-blushed skin without streaks and matures more precociously than the other ?Gala? clones, but with the same range of edaphoclimatic adaptation.

ABSTRACT:Sudden deaths after colostrum ingestion in kids and lambs born to mothers grazing in areas with Amorimia septentrionalis have been reported in the Brazilian northeastern semi-arid region, in Paraíba state. This study aimed to determine whether the sodium monofluoracetate (MF) contained in A. septentrionalis is eliminated in milk, causing the death of kids. After confirming gestation on the 25th day after mating, 26 goats were randomly distributed into three groups. In Group 1, eight goats received fresh leaves of A.
