Estrategias combinadas para la obtención de un vino Tannat con un contenido moderado de alcohol. [Combined strategies for obtaining a Tannat wine with moderate alcohol content.]. [conference proceedings].
RESUMEN.- En este trabajo se buscó a través de la combinación de 2 estrategias reducir el contenido de alcohol en vinos de la variedad Tannat. La primera estrategia consistió en el screening dentro de clones uruguayos de Tannat Con este fin se muestrearon durante tres vendimias consecutivas 10 clones uruguayos de Tannat y se utilizó como referencia el clon francés 717 en viñedos.
Estudio de precursores aromáticos en clones comerciales de Tannat y seguimiento de su evolución durante la maduración. [Study of aromatic precursors in commercial Tannat clones and monitoring of their evolution during ripening.]. [conference proceedings].
RESUMEN.- La variedad Tannat desde el punto de vista del aroma, resulta una variedad neutra pero capaz de aportar precursores aromáticos que son de interés en la elaboración de vinos de guarda. Los principales precursores aromáticos presentes son compuestos glicosidados y carotenoides. Durante 3 vendimias consecutivas se estudió el contenido de precursores aromáticos de 8 clones comerciales de Tannat (ENTAV-INRA:398, 399, 472, 474, 475, 717, 794 Y 944).
Performance assessment of furrow irrigation in two different soil textures under high rainfall and field slope conditions. [Análisis del rendimiento del riego por surcos en dos texturas de suelo diferentes bajo condiciones de alta precipitación y topografía del suelo.]. [Análise do desempenho da irrigação por sulco em duas texturas diferentes de solo sob condições de alta precipitação e inclinação do solo.]
ABSTRACT.- Furrow irrigation systems have been widely evaluated around the world. However, there is no national data indicating how efficient furrow irrigation is under Uruguayan conditions. The objective of the present work was to evaluate the performance of a system of furrow irrigation in two different soils texture. Seventeen irrigation events were analyzed in sugar-cane cultivation in northern Uruguay during 2016-17 and 2017-18 irrigation seasons. The water advance and recess curves were determined; flow rate during irrigation and runoff were monitored.
Sodium accumulation vs. nitrate leaching under different fertigation regimes in greenhouse soils in South Uruguay. [Acumulación de sodio vs. lavado de nitrógeno en suelos bajo invernadero en el sur de Uruguay con diferentes regímenes de fertirriego.]. [Acúmulo de sódio vs. lixiviação de nitrogênio sob solos de estufas no sul do Uruguai com diferentes regimes de fertirrigação.].
ABSTRACT.- In greenhouse conditions, soil salinity and N leaching depend on the provision of irrigation, the irrigation water quality and the application of fertilizers and organic amendments. The objective of this study was to quantify and analyze the accumulation and/or leaching process of NO3- and Na+ in greenhouse tomato production in the south region of Uruguay in fine-textured soil under different fertigation regimes. The study was conducted in four tomato crops during 2019/20/21 seasons. Three fertigation regimes were applied. Irrigation volume was the same for all treatments.
