“…The tomato (Solanum lycopersicum L.) is one of the most important vegetable crops worldwide and one of the most demanding of water [7]. The seasonal water requirement for processing tomato is estimated to be approximately 5000 to 6000 m 3 ha −1 , which, in semi-arid areas, is almost totally supplied by irrigation [6].…”

“…In these areas, due to climate change, the frequency and severity of prolonged periods of drought, as well as strong seasonal variation in the water budget, are predicted [2][3][4]. In this context, both use of the non-conventional waters (e.g., treated wastewater) and appropriate techniques of water saving, can be used to reduce the gap between the supply and demand of irrigation water [5,6]. The tomato (Solanum lycopersicum L.) is one of the most important vegetable crops worldwide and one of the most demanding of water [7].…”

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.

“…The results obtained by several researchers support the results obtained in this study. For example [50,27,22] , pointed out that the marketable yield under the FI treatment provided the highest values compared with RDI and PRD. Kuscu et al [51] reported that the highest marketable tomato yields were observed with FI, and decreasing the irrigation rate generally improved the dry matter of fresh tomato fruits.…”

“…Among all treatments over the two years, there are no significant effects (p>0.05) on IWUE values. Similarly, the effects of water stress on the IWUE have been pointed out by several researchers, and they noted that there were not any significant differences in IWUE among the different water regimes that they used [50,64] .…”

Water resources are subjected to ever-increasing supply constraints due to extensive agricultural water demand for irrigated lands. Therefore, water-saving irrigation strategies need to be explored. The present study was conducted to explore the possibilities of using regulated deficit irrigation (RDI) and partial root zone drying irrigation (PRD) methods as water-saving irrigation techniques for subsurface irrigation. The objective of this study are to assess the effects of RDI and PRD irrigation on the water productivity of vegetable crops (tomato) under SSD systems in arid climatic conditions, and to compare the responses of tomato crops to PRD, RDI, and FI under an SSD system in terms of productivity, crop quality, and the amount of water saved. The field experiment was conducted during the fall 2014-2015 and 2015-2016 Citation: Hashem M S, El-Abedin T Z, Al-Ghobari H M.
