“…Processing tomato crops grown under partial root-zone deficit irrigation increased solid content and improved taste and sensory quality (Zegbe- Domínguez et al 2003); potato grown under RDI during late tuber filling to maturing stages at a level near 60 % of the control increased the proportion of marketable tuber class (by 20 %) compared to the fully irrigated control with no change in tuber yield (Shahnazari et al 2007); tomato under RDI reduced the incidence and severity of blossom end rot (a troublesome disease affecting fruit quality), thus improving end-use quality (Sun et al 2013b). However, oilseed rape under RDI decreased seed oil content substantially (Ghobadi et al 2006); tomato under RDI decreased the size of the fruits (Kirda et al 2007).…”

Agriculture consumes more than two thirds of the total freshwater of the planet. This issue causes substantial conflict in freshwater allocation between agriculture and other economic sectors. Regulated deficit irrigation (RDI) is key technology because it helps to improve water use efficiency. Nonetheless, there is a lack of understanding of the mechanisms with which plants respond to RDI. In particular, little is known about how RDI might increase crop production while reducing the amount of irrigation water in real-world agriculture. In this review, we found that RDI is largely implemented through three approaches: (1) growth stage-based deficit irrigation, (2) partial root-zone irrigation, and (3) subsurface dripper irrigation. Among these, partial root-zone irrigation is the most popular and effective because many field crops and some woody crops can save irrigation water up to 20 to 30 % without or with a minimal impact on crop yield. Improved water use efficiency with RDI is mainly due to the following: (1) enhanced guard cell signal transduction network that decreases transpiration water loss, (2) optimized stomatal control that improves the photosynthesis to transpiration ratio, and (3) decreased evaporative surface areas with partial root-zone irrigation that reduces soil evaporation. The mechanisms involved in the plant response to RDI-induced water stress include the morphological traits, e.g., increased root to shoot ratio and improved nutrient uptake and recovery; physiological traits, e.g., stomatal closure, decreased leaf respiration, and maintained photosynthesis; and biochemical traits, e.g., increased signaling molecules and enhanced antioxidation enzymatic activity.

“…Outra tecnologia que pode possibilitar o uso de água salina na irrigação pode ser a divisão do sistema radicular em duas ou mais parte o que já vem sendo estudado em diversas culturas com ênfase para o aumento na eficiência do uso da água; os resultados obtidos demonstram a viabilidade desta tecnologia (Yang et al, 2012;Sun et al, 2013).…”

R E S U M OO uso de água salina na irrigação é um desafio para pesquisadores e produtores rurais, sendo fundamental o desenvolvimento de novas estratégias para manejo da irrigação utilizando essas águas. Os tratamentos foram constituídos por seis estratégias de aplicação de água salina (T1 -Água de baixa salinidade (S 1 -0,5 dS m ) durante todo o ciclo; T3-S 1 e S 2 durante todo o ciclo; T4-S 1 e S 2 , com divisão do sistema radicular por um filtro plástico; T5-S 1 e S 2 , com divisão do sistema radicular alternando-se as águas a cada 15 dias; T6-S 1 e S 2 , sem divisão do sistema radicular alternando-se as águas a cada 15 dias). Foram realizadas cinco colheitas de frutos e as plantas foram coletadas aos 100 dias após o transplante e avaliadas quanto às seguintes variáveis: número de folhas, área foliar, altura, diâmetro do caule, massa seca de folhas, massa seca de caule, massa seca de frutos, número de cachos, número de frutos e produção de frutos. A maioria das variáveis foi afetada pela salinidade da água de irrigação. O maior rendimento de frutos foi obtido com uso de água de baixa salinidade e quando se realizou mistura de água e alternando-as quinzenalmente, demonstrando a viabilidade dessas técnicas. Irrigation strategies with saline water on cherry tomato in greenhouse A B S T R A C TThe use of saline water for irrigation is a challenge for researchers and farmers, being fundamental to develop new strategies for irrigation management using these waters. Treatments consisted of six strategies of saline water application (T1-low salinity water (S 1 -0.5 dS m -1 ) during entire cycle; T2-saline water (S 2 -3.5 dS m -1 ) during entire cycle; T3-S 1 and S 2 during entire cycle; T4-S 1 and S 2 , with root system divided by a plastic filter; T5-S 1 and S 2 , with root system division and alternance of S1 and S2 each 15 days; T6-S 1 e S 2 , without root system division, with water alternance every 15 days). Five harvests were carried out and plants were sampled 100 days after transplanting for evaluation of the following variables: number of leaves, leaf area, height, stem diameter, dry mass, number of fruits, mean mass of fruits and fruit yield. Most variables were affected by irrigation water salinity. The higher fruit yield was obtained using low salinity water and when waters were mixed and alternated each fifteen days, which demonstrates the viability of these techniques.

“…Among those enzymes, invertase plays a crucial role in regulating hexose concentration in tomato fruits (Ho 1996), and its activity can be modulated by ABA (Ruan et al 2010). Compared to DI, PRD treatment was shown to induce greater ABA concentration in the xylem of tomatoes (Wang et al 2010;Sun et al 2013). The hormone may be accumulated to a high level in the fruits, stimulating invertase activity and resulting in higher hexose concentration in the fruits (Ruan et al 2010).…”

Sun Y., Holm P.E., Liu F., 2014. Alternate partial root-zone drying irrigation improves fruit quality in tomatoes. Hort. Sci. (Prague),.Alternate partial root-zone drying (PRD) irrigation and deficit irrigation (DI) are water-saving irrigation strategies. Here, comparative effects of PRD and DI on fruit quality of tomato (Solanum lycopersicum L.) were investigated. The results showed that the irrigation treatments had no effect on tomato yield but significantly affected several organic and mineral quality attributes of the fruits. Compared to DI, PRD significantly increased the fruit concentrations of Ca and Mg, and fruit juice concentrations of total soluble solid, glucose, fructose, citric and malic acid, P, K and Mg. It is concluded that PRD is better than DI in terms of improving fruit quality, and could be a promising management strategy for simultaneous increase of water use efficiency and fruit quality in tomatoes.
