“…However, authors concluded that in regions where water scarcity exists, farmers should adopt water saving strategies to achieve economically sustainable crop production. Marouelli and Silva (2007) and Patanè and Cosentino (2010) reported that the effects of soil water deficit at different crop stages on processing tomato fruit yield and quality are not yet well defined, because these are relatively complex and site-specific, and they are mainly affected by environmental conditions. Therefore, added studies to better define acceptable levels of water stress to apply in relation to different processing tomato hybrids, irrigation methods and growing areas are necessary.…”

Processing tomato grown in Mediterranean region required high irrigation volume throughout growing season. A two-year study was carried out in order to investigate the effects of deficit irrigation (DI) and regulated deficit irrigation (RDI) on processing tomato cultivated under sub-arid conditions. A comparison between the irrigation management linked to common practice adopted by farmer and the irrigation management based on crop evapotranspiration (ETc) demand was also done. The tomato cv. Genius F1 was cultivated under five water regimes: minimal irrigation (I0), as irrigation only at transplanting and during fertilising; DI, to restore 60% ETc; RDI, to restore 60%-80%-60% ETc across the three main tomato phenological stages; full irrigation (FI), to restore 100% ETc; and farmer irrigation (FaI), as irrigation following the subjective farmer method. Compared to FI, under the FaI regime, the seasonal irrigation volume was 31% and 26% higher in the 2009 and 2010, respectively, with not significant yield increase between the two water regimes. Among the irrigation regimes, only the RDI showed similar yield values over the two years, although 2010 was climatically less favourable. For the water use efficiency related to the marketable yield (WUEy), among the irrigation regimes, RDI showed the higher value together with FI. Finally, the Ky was 0.91, which indicates moderate water stress tolerance for processing tomato cultivated in Mediterranean regions. In conclusion, the data obtained in the present study demonstrate that in Southern Italy the irrigation planning followed by the farmer does not follow the principles of sustainable irrigation. Moreover, with the adoption of the RDI strategy, it is possible to save about 27% of water maintaining high WUEy value with an increase of fruit quality. The adoption of this regime could be suggested in processing tomato cultivated under Mediterranean climate saving water in both the vegetative and ripening periods.

“…Soil water potential is related to soil water content [12] , and also used as an indicator to directly guide irrigation [13][14][15][16][17][18][19][20] . Some experiments showed that, the proper soil water potential is -25kPa for potato, -35kPa for radish, -50kPa for tomato.…”

“…Según Marschner (2002) con un défi-cit de agua, los frutos probablemente presentan una mayor respiración, situación que origina la conversión de ácidos a azúcares de forma más rápida. En tomate algunos autores (Patané et al, 2011;Favati et al, 2009;Marouelli y Silva, 2007) reportan que cuando las plantas de tomate sufren de estrés hídrico tienen una reducida absorción de agua, e incrementan la producción de ácidos en los frutos como mecanismo de adaptación al estrés.…”

Fresa variedad Ventana en fructificación.Foto: Y.A. Deaquiz RESUMENLa fresa es un cultivo de gran importancia económica para muchos agricultores de Colombia, principalmente para los de clima de frío de Boyacá y Cundinamarca; sin embargo, en estas zonas el bajo nivel de tecnificación del sistema de producción y el desconocimiento del manejo adecuado del riego en el cultivo de fresa conlleva al uso ineficiente del recurso hídrico. Por lo anterior, el objetivo de esta investigación fue evaluar el efecto de diferentes láminas de riego sobre la producción y calidad poscosecha de los frutos de fresa var. Ventana. Se utilizó un diseño experimental completamente al azar con cinco tratamientos y cuatro repeticiones. Los tratamientos correspondieron a cinco láminas de riego determinadas por cinco coeficientes multiplicadores de la evaporación (0,8; 1,0; 1,2; 1,4 o 1,6 de la evaporación medida dentro del invernadero). Para la siembra se utilizó turba rubia como sustrato, las aplicaciones se realizaron mediante sistema de riego por goteo. La lámina de riego de 1,6 presentó los mejores resultados de masa fresca de hojas, masa seca de hojas, corona y peciolos, área foliar y sólidos solubles totales de frutos; mientras que la lámina de riego de 1,4 obtuvo los mejores resultados de masa fresca de corona y peciolos, raíz, masa seca de raíz, frutos y relación de madurez. El coeficiente de riego de 1,4 presentó los mejores rendimientos y mantuvo una alta eficiencia en el uso del agua. El manejo de diferentes láminas de riego afecta las características organolépticas de los frutos de fresa.Palabras clave adicionales: uso eficiente del agua, estrés hídrico, evaporación, productividad, poscosecha.
