“…Moreover, comparing yield displayed in the present study with the last available data reported in the literature, "Pearson", "C33", "HEINZ 2274" and "HEINZ 3402" performed as well as in California, New Zealand, Turkey and Spain environments, respectively (Barrios-Masias and Jackson, 2014;Burgmans and Bussell, 1983;Ersahin and Karaman, 2001;Gutiérrez et al, 2019). On the other hand, "E6203" and "Brigade" recorded lower values (∼ 30%) compared to Californian and Israelian environments, respectively (May and Valencia, 1990;Lowengart-Aycicegi et al, 1998). Nonetheless, being marketable yield affected by several factors, more studies are needed to further dissect the results presented in this study by using different plant density levels and cropping systems, and more are expected by possible different responses to innovative biofertilizers (Ronga et al, 2019a(Ronga et al, , 2019b.…”

“…In particular, an irrigation technique was developed on the tomato that consists of interrupting watering (irrigation cut-off) during the ripening period, with the final goal of saving water and improving dry matter accumulation, although this technique also causes a reduction in the marketable yield (Cahn et al, 2003;Lowengart-Aycicegi et al, 1999). Our results are in agreement with those obtained by Cahn et al (2001) because the irrigation interrupted at the onset of fruit ripening does not affect yield, especially in terms of marketable dry matter; whilst maximises WUE, resulting in a water saving.…”

Yield, quality and water use efficiency of processing tomatoes produced under different irrigation regimes in Mediterranean environment

Marketable yield is the main objective in tomato production, but fair values for quality parameters are also becoming very important. A research project was undertaken for two years to assess the impact of water-saving techniques on yield, fruit quality and water use efficiency (WUE) of processing tomato (cv. Pullrex) in the Mediterranean environment. Additionally, to better understand how irrigation may affect tomato traits, different statistical techniques were applied to the results. Total yield was reduced by 37% on average in both years when half of the crop evapotranspiration (ET) was restored, and maximum marketable tomato yield was obtained under irrigation when 100% of the crop ET was restored. Irrigation cut at tomato veraison (irrigation cutback treatment) did not affect the yield, enhanced fruit quality and maximised WUE, thus contributing to water saving. Through the application of irrigation cutback toward the end of the tomato cycle, there is a possibility to improve tomato quality and, at the same time, save irrigation water. Principal component analysis confirmed that the cutback of irrigation was well correlated with tomato quality

“…Drip irrigation management affects both tomato yield and SSC (Cahn et al, 2001(Cahn et al, , 2003Dumas et al, 1994;Lowengart-Aycicegi et al, 1999;May and Gonzales, 1999). All reported that imposing soil moisture stress during fruit sizing and ripening reduced yield while increasing SSC.…”

Fruit soluble solids concentration (SSC) is an important quality factor for tomatoes (Lycopersicon esculentum Mill.) grown for processing. The use of drip irrigation often results in undesirably low SSC. The effects of late-season irrigation management on fruit yield and SSC was investigated in a series of drip-irrigated field trials in California from 2000–04. The effects of irrigation cutoff or deficit irrigation implemented 40 to 50 days preharvest (the period corresponding to the initiation of fruit ripening) were compared to a standard grower practice of irrigation cutoff 20 days preharvest. Irrigation cutoff 40 to 50 days preharvest increased SSC but resulted in substantial yield loss, with significantly reduced brix yield (Mg fruit solids ha-1). By contrast, deficit irrigation significantly increased SSC compared to the standard practice, with no significant loss of brix yield. In three commercial fields the effect of deficit irrigation on fruit SSC was investigated. Fruits were sampled on three dates: 1) 4 to 5 weeks preharvest, early-ripening, pink-stage fruit only, 2) about 1 week preharvest, both late-ripening, pink-stage fruit and early-ripening fruit now fully ripe, and 3) commercial harvest, composite of early- and late-maturing fruit. SSC increased in response to soil moisture stress induced by deficit irrigation, with late-maturing fruit as much as 1.6 °brix higher than fruit maturing before significant soil moisture stress. However, once a fruit reached the pink stage of maturity, its SSC was not affected by subsequent soil moisture stress. An additional five commercial field trials were conducted to compare growers' irrigation practices with greater degrees of deficit irrigation. In each field the grower's deficit irrigation regime was compared to a reduced treatment receiving 25% to 50% less water over the final 4 to 7 weeks before harvest. Across fields, applying 20% to 60% of reference evapotranspiration (ETo) over the fruit ripening period resulted in acceptable SSC without significant brix yield reduction. We conclude that deficit irrigation initiated during early fruit ripening provides a flexible tool for SSC management. Brix monitoring of earliest ripening fruit can help classify fields as to the severity of irrigation deficit required to reach desirable SSC at harvest.
