Use of the VegSyst model to simulate seasonal dry matter production, N and K uptake and evapotranspiration in greenhouse soil-grown tomato in Uruguay.
ABSTRACT.- The VegSyst model, initially developed for nitrogen (N) and irrigation recommendations for greenhouse-grown vegetable crops in southeastern Spain, was calibrated and validated for greenhouse tomato cultivated in soil in Uruguay (South America) for autumn and spring growing seasons. Additionally, the performance of the recalibrated VegSyst model was compared to the calibration for tomato grown in Almeria greenhouses of VegSyst model V3.
Resistance to bacterial wilt in Solanum commersonii Dun. [Resistencia a la marchitez bacteriana de la papa en Solanum commersonii Dun.]. [Special Issue 25 Years Agrociencia].
ABSTRACT.- The levels of resistance to bacterial wilt (BW) of potatoes caused by Ralstonia solanacearum (Rs) are limited. Solanum commersonii (cmm) is a wild tuber-bearing potato highlighted for its resistance to BW.
First report of root and crown rot caused by Dactylonectria novozelandica on strawberry in Uruguay. [Primer reporte de Dactylonectria novozelandica causando necrosis de raíz y corona en frutilla en Uruguay]. [Primeiro relato de Dactylonectria novozelandica causando necrose de raiz e coroa em morangos no Uruguay].
ABSTRACT.- Since 2015, a high mortality rate of strawberry plants has been observed in the north of Uruguay related to crown and root diseases caused by a pathogens complex. In 2016, associated with the death of plants, Cylindrocarpon spp. was isolated with a frequency of 42.4 %, ranking third, preceded by Neopestalotiopsis sp. and Fusarium spp. Aiming to increase the knowledge of the pathogens that integrate the complex, three isolates of Cylindrocarpon spp. were characterized by molecular, morphological and pathogenicity analyses in strawberry plants.
Evaluación de la resistencia a marchitez bacteriana en germoplasma avanzado de Papa (Solanum tuberosum). 153. (resúmen).
Una de las principales enfermedades que afecta al cultivo de la papa es la marchitez bacteriana, causada por Ralstonia solanacearum. Con este trabajo se busca caracterizar la resistencia a marchitez bacteriana en germoplasma seleccionado del Programa nacional de papa y otros materiales promisorios de diverso origen.
Evaluación de la resistencia a tizón tardío (Phytophthora infestans) en genotipos de una colección núcleo de parientes silvestres de papa en condiciones controladas. 273. (resúmen
El tizón tardío de la papa, causado por Phytophthora infestans, es la enfermedad más importante del cultivo a nivel mundial. En este trabajo se evaluó la resistencia a P. infestans en una colección núcleo de 43 clones de parientes silvestres.
