ABSTRACT.
Knowledge about contributing factors to yield loss is essential for sustainable intensification of agriculture, which has the objective to increase both, yield and environmental sustainability. This study aimed to identify strategies to reduce the distance between under-performing and best-yielding greenhouse tomato crops in the south region of Uruguay. Gap to attainable yield was described and main causes of yield variability were explored by combining regional agronomic diagnosis and yield gap analysis. A sample of 110 tomato greenhouses within 23 farms during 2014/15 and 2015/16 were assessed. The variables assessed were classified in four
groups: growth defining, growth limiting, growth reducing factors and yield components. Yield ranged from 0.9 to 24.3 kg m−2. Cumulated photosynthetically active radiation (PAR) intercepted was the most correlated with yield. We analyzed two complementary ways of increasing yield: (1) modifying growth-defining factors to increase cumulated PAR intercepted and attainable yield, and (2) modifying growth-limiting and reducing factors responsible for the gap to attainable yield at a given level of cumulated PAR. PAR interception could be increased by adjusting transplanting dates to modify daily incident radiation, improving transmissivity of greenhouses and fraction PAR intercepted by canopy. We classified crops in three groups of cumulated PAR intercepted and yield. The average gap between actual and attainable yield was 34%. The strategy to close that gap differed among groups, but K nutrition was common to all. Results from this study allowed us to deliver relevant and actionable information to better inform discussions among farmers and their technical advisors.

Proyecto FPTA 228: Estudios biológicos de Oryzophagus oryzae como base para la implementación de buenas prácticas de manejo del cultivo de arroz en diferentes zonas de Uruguay. Período de Ejecución: Dic. 2006-Mar. 2010.

El proyecto surgió para responder a la inquietud de los sectores involucrados en la producción de arroz. Aunque este insecto se detectaba en todas las regiones productivas, hasta el momento no se contaba con estudios específicos de su biología, y de su población, distribución, e incidencia de daños en las diferentes zonas cultivadas (productivas) del país. Desde 2006 a 2010 se realizaron trabajos de campo en las zonas norte y este del país siguiendo las poblaciones de larvas y adultos de gorgojos acuáticos a lo largo del período de cultivo. También se realizaron trabajos durante el invierno relevando la presencia de adultos en los rastrojos, y en la primavera para detectar plantas
hospedero alternativas. |
