“…In a twoyear greenhouse grown fresh market tomato study, Nuruddin et al (2003) reported significantly higher WUE under no water stress treatment with respect to others deficit irrigation treatments in the first year of their experiment, and no significant differences between their no water stress and four mild and moderate water stress treatments in their second year. Conversely, in the most of the literature, increases in the WUE in tomato under water deficit conditions have also been reported (Topcu et al, 2007;Favati et al, 2009;Giuliani et al, 2011;Patanè et al, 2011;Chen et al, 2013). Finally, in our study the lowest WUEy value was observed for FaI, showing once again that with this regime the farmer used too much water in relation to the marketable yield obtained.…”

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.

“…Nesse contexto, para se ter o uso sustentável da água na agricultura, torna-se necessária a adoção de estratégias de irrigação que permitam a economia de água e mantenham os rendimentos satisfatórios das culturas, melhorando, assim, a eficiência do uso da água (PARRY et al, 2005;TOPCU et al, 2007). Assim, objetivou-se, com esta pesquisa, avaliar os aspectos agronômicos do tomateiro "Caline IPA 6" cultivado sob diferentes taxas de reposição hídrica em área do semiárido paraibano, a fim de estabelecer estratégias de cultivo na região.…”

Resumo -Na Região Nordeste do Brasil, a instabilidade climática e a ocorrência de veranicos impossibilitam o cultivo adequado do tomate em todas as épocas do ano. Assim, faz-se necessário o uso da irrigação para suprir a demanda hídrica da cultura, porém tanto o excesso como o déficit de água no solo podem afetar a produção e a qualidade dos frutos. Nesse contexto, objetivou-se avaliar, com este trabalho, aspectos agronômicos do tomateiro "Caline IPA 6" cultivado sob diferentes taxas de reposição hídrica em área do semiárido paraibano. O experimento foi conduzido na área experimental do Setor de Fruticultura e Ecofisiologia Vegetal da Universidade Estadual da Paraíba (UEPB), campus de Catolé do Rocha (PB), onde 5 níveis de reposição hídrica foram estudados (50, 75, 100, 125 e 150% da evapotranspiração de referência -ETo) no delineamento em blocos ao acaso com 4 repetições e 9 plantas úteis por parcela. A ETo foi estimada com base no modelo de PenmanMonteith. Avaliaram-se variáveis agronômicas e produtivas das plantas de tomate. As lâminas de irrigação influenciaram significativamente as características analisadas, sendo constatado que os aspectos agronômicos do tomateiro "Caline IPA 6" são afetados positivamente com lâminas de irrigação acima de 100% da necessidade da cultura. Já a variação na reposição hídrica no consumo do tomateiro afeta os componentes de produção com maior intensidade no número de frutos e na produção por planta. Palavras-chave -Lycopersicon esculentum Mill. Lâminas de água. Qualidade do fruto. Produtividade.Abstract -In Northeast Brazil, climate instability and the occurrence of dry spells preclude proper growing tomato in all seasons. Thus, it is necessary the use of irrigation to meet the water demand of the crop, but both excess and deficit soil water can affect the production and fruit quality. In this context, it was evaluated, with this work, agronomic aspects of tomato "Caline IPA 6" grown under different rates of fluid replacement in semiarid area of Paraiba. The experiment was conducted in the experimental area of the Sector of Fruit Crops and Plant Ecophysiology of Paraíba State University, campus Catolé do Rocha (PB), where 5 levels of water replacement were studied (50, 75, 100, 125 and 150% of ETo) in randomized complete block design with random 4 replications and 9 plants per plot. The ETo was estimated based on the Penman-Monteith model. Were evaluated agronomic and productive variables in tomato plants. The irrigation depths significantly influenced the characteristics analyzed, being evidenced that the agronomic aspects of tomato "Caline IPA 6" are positively affected with irrigation levels above 100% of the need for culture. The variation in the water replacement in the consumption of tomato affects yield components with greater intensity in fruit number and yield per plant.

“…However, the available literature presents some discrepancies, linked to the cultivars used and/or to the phenological period of application of deficit irrigation treatments [7]. Moreover, most of these studies are in greenhouses or under controlled conditions [27][28][29][30][31][32][33][34]. Notwithstanding, there is still little understanding on the mechanisms of PRD in different tomato cultivars grown under open field conditions, and any agro-climatic parameters (e.g., air temperature) can influence the plant response.…”

Due to climate change, the application of water saving strategies is of particular interest. The aim of this study was to evaluate the effects of deficit irrigation (DI) and partial root-zone drying (PRD) techniques on the crop water stress index (CWSI), water use efficiency (WUE), and quality parameters in processing tomatoes grown in open field conditions in a Mediterranean climate. Two cultivars were grown for two growing seasons under four irrigation regimes as follows: (i) IR 100 : full irrigation by restoring 100% of the maximum tomato evapotranspiration (ET c ); (ii) IR 70DI : 70% of the amount of water given to the IR 100 ; (iii) IR 70PRD : 70% of the amount of water given to the IR 100 by applying partial root-zone drying and (iv) IR 0 : irrigation only at transplanting and during fertigation. During the flowering period, the first growing season was characterized by an absence of rainfall and by higher temperatures also showing a higher CWSI. Despite, under IR 70PRD , the CWSI was significantly higher than under IR 70DI , the marketable yield obtained was significantly higher. Both IR 70DI and IR 70PRD regimes received approximately 24% less water than IR 100 , but the yield reduction with relation to the optimum regime was equal to 16.2% under IR 70DI , and only 7.6% under IR 70PRD . The WUE increment of IR 70PRD with respect to IR 100 was equal to 27% in the first growing season and to 17% in the second one, showing that the positive effect of PRD on the WUE is more evident in the more stressed year. Finally, the results from the principal component analysis (PCA) showed that the two cultivars had different qualitative responses in the two extreme regimes (IR 100 and IR 0 ) but not under PRD and DI regimes.
