“…Además, los valores promedio globales, fueron de 1,99 dS/m en T 0 y 2,04 dS/m en T 1 . Al respecto, estudios realizados por Magán et al (2008), demostraron que en el cultivo de tomate sin suelo el rendimiento se redujo a partir de valores de CE de 3,3 dS/m en solución nutritiva.…”

“…Los mayores valores de CE se presentaron desde la quincena 10 hasta el final del cultivo, debido a que este periodo coincidió con el inicio de la primavera, donde se registraron incrementos en la radiación solar y la temperatura y una reducción de la humedad ambiental, que consecuentemente incrementó la evapotranspiración del cultivo. Al comparar los valores promedio global de CE de la solución nutritiva en el gotero respecto a los valores de CE obtenidos en drenaje, se observaron diferencias de alrededor de 0,5 dS/m, lo cual según Magán et al (2008), desde el punto de vista práctico de manejo del cultivo, se considera aceptable.…”

“…La mayor diferencia (15%) entre tratamientos se presentó en la quincena 10. En general, los valores de drenaje obtenidos en las diferentes quincenas, se consideran normales para el manejo de riego en cultivos sin suelo en condiciones con aguas de regular calidad (Magán et al, 2008), lo cual sugiere que el manejo del riego en ambos tratamientos, estuvo dentro de los rangos normales de manejo convencional utilizado en cultivos comerciales de la región.…”

El objetivo del presente trabajo fue evaluar el efecto del peróxido de hidrógeno (H2O2) como fuente de oxígeno en la rizosfera, en tomate injertado (cv. Durinta/cv. Maxifor) y utilizando fibra de coco como sustrato. El estudio se llevó a cabo entre los años 2009 y 2010. Se utilizaron dos tratamientos: un control sin H2O2 (T0) y otro con H2O2 (T1) aplicado en cada riego. Se evaluaron parámetros de: i- fertirrigación: oxígeno (O2), pH, conductividad eléctrica (CE) y porcentaje de drenaje; ii- crecimiento: diámetro basal y altura de planta; iii- rendimiento y iv- calidad de fruto: firmeza, grados Brix, peso seco y pH. Durante el ciclo de vida del cultivo, el valor promedio de [O2] en la solución de riego fue 9,92 mg/l en T0 y 12,1 mg/l en T1, mientras que en la solución drenada la [O2] fue de 8,75 mg/l en T0 y de 9,22 mg/l en T1. Aunque se presentaron diferencias significativas (P<0,05) en [O2] entre tratamientos durante algunos periodos del ciclo de cultivo, en el T0 la [O2] no alcanzó un valor crítico que afectara la adecuada oxigenación de las raíces. Por tanto, no hubo efecto del tratamiento con peróxido de hidrógeno (T1) sobre parámetros de fertirrigación, crecimiento, rendimiento y calidad del fruto del cultivo.

“…According to that study, there were only small effects of climate and cultivar on the threshold EC value for yield. And the decrease of fresh fruit yield with salinity was mostly due to a linear decrease of the fruit weight of 6.1% per dS m -1 from an threshold EC of 3.0 dS m -1 for marketable fruits, whereas reduction in fruit number with salinity made a smaller relative contribution to reduced yield (Magan et al, 2008). The level of the NO3 -was also significantly related to the tomato height and yield (p < 0.05) (Zhang et al, 2011).…”

Nutrient accumulation in surface soil has become a serious problem for cucumber production in greenhouse. However, still in many cases, soil management practices are only focused on maintaining crop yield, regardless of sustainability related with soil chemical properties. This study was conducted to propose a sustainable soil management practice by investigating the impact of cover crop species and nitrogen rate of fertigated solution on cucumber yield and soil chemical properties in greenhouse condition. Rye and hairy vetch were tested as a fallow cover crop, and each amount of urea (1/2, 3/4, 1 times of N fertilizer recommendations), determined by soil testing result, was supplied in fertigation plots as an additional nitrogen source. The result showed that the yield of cucumber was higher in rye treatment than control and hairy vetch treatment. In addition, rye effectively reduced EC and accumulated nutrients from the soil. Meanwhile, N concentration of fertigated solution showed no significant effect on the growth and yield of cucumber. Consequently, these results suggest that it is desirable to choose rye as a fallow catch crop for sustainable cucumber production in greenhouse.

“…Other researchers, studying hydroponic tomato cultivation, also observed decrease in production (5.2, 5.3, 7.7 and 6.7% per dS m -1 ) as a function of the increase in nutrient solution salinity (Amor et al, 2001;Magán et al, 2008;Cosme et al, 2011;Gomes et al, 2011).…”

A B S T R A C TThe use of brackish water in agriculture can cause salinization of soils and reduce plant yield. This problem can be minimized by hydroponic cultivation, which improves plant development. The aim of this study was to evaluate the yield of cherry tomatoes grown in hydroponic system with substrate under salinity levels of the nutrient solution (NS), exposure time to salinity and irrigation frequency. The experiment was conducted in a greenhouse, in a randomized complete block design, in a 6 x 2 x 2 factorial scheme with five replicates: six salinity levels of NS prepared with brackish water (3.01; 4.51; 5.94; 7.34; 8.71 and 10.40 dS m -1 ); two exposure times to NS (60 and 105 days) and two irrigation frequencies (one irrigation per day and irrigation every two days). Yield and production components of cherry tomatoes cv. 'Rita' were evaluated. NS salinity affected plant yield, reducing fruit production, which was more significant when plants were subjected to a longer time of exposure to salinity. There was no difference between NS applications on fruit production, when these applications were performed once a day or once every two days.Rendimento do tomate cereja em função da salinidade da água e do turno de rega R E S U M O O uso de água salobra na agricultura pode promover a salinização dos solos reduzindo a produção das plantas. Este problema é passível de ser minimizado nos cultivos hidropônicos visto que promove, às plantas, melhores condições de desenvolvimento. Objetivou-se, neste trabalho, avaliar o rendimento do tomate cereja cultivado em hidroponia com substrato em função da salinidade da solução nutritiva preparada com água salobra (SN), do tempo de exposição à salinidade e do turno de rega. O experimento foi conduzido em casa de vegetação em blocos casualizados em esquema fatorial 6 x 2 x 2 com cinco repetições, sendo: seis níveis de salinidade da SN preparada com água salobra (3,01; 4,51; 5,94; 7,34; 8,71 e 10,40 dS m -1 ); dois tempos de exposição à SN (60 e 105 dias) e dois turnos de rega (uma irrigação por dia e uma irrigação a cada dois dias). Foram avaliados a produção e os componentes de produção do tomate cereja cultivar 'Rita' . A salinidade da SN afetou o rendimento das plantas reduzindo a produção de frutos sendo esta redução mais acentuada quando as plantas foram submetidas a um tempo maior de exposição à salinidade. Não houve diferença entre as aplicações de SN sobre a produção de frutos quando essas aplicações foram realizadas uma vez por dia ou uma vez a cada dois dias.
