“…Because larger sizes tend to have a higher market value, the EC increase from 2 to 2.5 dS · m -1 resulted in a loss of market value. These results were consistent with those obtained in a large number of studies, in which an increase in salinity has been reported to cause a reduction in mean fruit weight (Hayward and Long, 1943;Ho and Adams, 1995).…”

“…The different treatments did not show significant differences in the evaluated fruit quality parameters, except for the total soluble solids in the treatments that decreased with increasing distribution of nutrient solution. An increase in salinity values has been related to a significant increase in the percentage of dry matter, acidity, total soluble solids (°Brix), and fruit osmotic concentration (Hayward and Long, 1943). However, in the present experiment, such a significant increase was not observed, which may have been the result of the following Sonneveld and Straver (1994).…”

“…Adapting the management of fertigation and salinity (expressed as ionic composition of the nutrient solution) to the production conditions is a highly influential factor in terms of an economic balance but is also an important factor for controlling the emission of pollutants into the environment (Massa et al, 2010;Urrestarazu et al, 2008a). From the 1930s and 1940s (Hayward and Long, 1943;Robbins, 1937) to the present (Adams, 1991;Adams and Ho, 1989;Cuartero and Fernández-Muñoz, 1998;Ho and Adams, 1995;Urrestarazu et al, 2005), two clear effects with increasing salinity have been described as follows: 1) productivity loss and 2) the increase of fruit quality parameters (e.g., total soluble solids, dry matter content, acidity, average fruit weight, and ionic concentration). To determine and quantify the production loss resulting from increased radical osmotic pressure, several experimental protocols have been described since the 1970s (e.g., Hoffman, 1985;Jobes et al, 1981;Maas and Hoffman, 1977).…”

In recent decades, salinity in the culture of tomatoes has been one of the most studied parameters. This study aimed to evaluate the effect of a moderate increase in salinity, fertigation distribution, and its control using thermography on a soilless culture of grafted tomato. A tomato crop (cv. Ramyle) grafted onto tomato rootstocks (cv. Emperor) was cultivated in coir crop units at the University of Almeria from Nov. 2012 to May 2013. A plot design subdivided with four blocks was used, with salinity values of 2.0 and 2.5 dS·m−1 in the main plots and fertigation distribution systems with either one (DD1) or four (DD4) drip manifolds in the subplots. The crop productivity was measured using total crop yield, commercial value, and size. The quality parameters in the fruits were not significantly affected. Thermographies were used to aid the control of differential transpiration exerted by salinity. The difference in salinity did not significantly affect the total or commercial production. However, despite being grafted plants, there was a statistically significant effect (P ≤ 0.05) on the fruit size distribution when the electrical conductivity (EC) of the nutrient solution was increased from 2.0 to 2.5 dS·m−1, with a lower production (16%) of large fruits and an increased production of smaller fruits. The DD4 system significantly increased large tomato production (22%) compared with DD1, and the quality parameters in the fruits were not significantly affected. As a result of the improvement in tomato size, the DD4 distribution system economically offset the required higher initial expenditure compared with the DD1 system. Thermography was revealed to be a robust, simple, and quick tool for diagnosing the effect of salinity on transpiration.

“…The values of EC, pH, and LF in fertigation drainage are frequently used parameters for the practical control of soilless systems (e.g., Gorbe and Calatayud, 2010;Hayward and Long, 1943;Urrestarazu et al, 2008b).…”

The management of water and nutrient ions, such as nitrate, has been studied extensively in recent decades. Increasingly efficient models have been developed for the use of water and nutrients through the automation of fertigation techniques. The application of a fertigation volume for a duration four times longer than applied on the control was evaluated. In Almería (Spain), one pepper crop and two tomato crops—with and without grafting—were grown between Oct. 2013 and June 2014 in a soilless system with a coir substrate. The effects on root growth, plant growth, production, and quality were measured. The following parameters for the fertigation of the nutrient solution and drainage were recorded: % drainage volume, electrical conductivity (EC) of the nutrient solution, pH, and concentration of nitrates and potassium. The absorption of potassium and nitrate, and the nitrate emissions of the drainage were estimated. The results showed an increase in the root volume and an improved distribution in the cultivation unit for the treatment application in the pepper crop. Slowing the applied fertigation improved the absorption of water and nitrates, and the production in the ungrafted tomato and pepper crops, while the grafted tomato crop was unaffected. Nitrate emissions were lower in the evaluated treatment of the pepper and ungrafted tomato crops. The fruit quality parameters were unaffected.

“…As mentioned above, salinity is commonly reducing growth and production of many vegetable crops such as tomatoes (Hayward and Long, 1943;Sanchez and Azuara, 1979;Li, 2000;Tantawy, 2007;Ebrahimizadeh et al, 2009). In this study and in agreement with previous studies, Salinity reduced plant height (Achilea et al, 2002;Agong et al, 2004;Hajer et al, 2006) and leaf area (Li and Stanghelni, 2001;Mulholland et al, 2002;Maggio et al, 2004;Agong et al, 2004), fresh weight (Hassan et al, 1999;Sonneveld, 2000;Amico et al, 2003;Hajer et al, 2006) as well as dry weight (Li, 2000).…”

Problem statement:This study was conducted to examine the effects of irrigation water pH and Salinity on the growth and absorption of P, Na, Ca, K by tomato. Approach:The study includes two Salinity and pH factors and is consisted from 12 treatment and three repetitions. Tomato seeding grown in foam trays were transplanted in the joune 2010 to bags filled with perte in an Greenhouse at Damghan Islamic Azad University of Iran. Plant were divided into groups then irrigated with the targeted sane and pH levels. Plants were hand-irrigated with fresh water and fertized with required nutritional solutions were prepared based on bed nutrients mitation. Greenhouse temperature was maintained in suitable level using air conditioner and its humidity was controlled by hygrometer and adjusted in the range of 60-80%. Water Salinity factors were consisted from four levels (0, 3, 6 and 9 dsm −1 ) and pH factor was consisted from three levels (6.5, 7.5 and 8.5). Salinity and pH treatments were adjusted with Nacl and H 2 SO 4 /N 2 CO 3 salts respectively. Study of the effects of Salinity and pH level on tomato were recorded and controlled depending on number of growing fruit, fertized flowers, plant dry weight, plant height, percentage of P, Na, Ca, K in leaves. Then results were studied by Anova Variance Analysis using SAS software and obtaining significant results, Dunken test was used for comparison of average levels in probabity level of 5%. Results: Data showed that all growth parameters such as plant height, leaf area, plant dry weight, percentage of P,Ca,K in leave responded negatively as the Salinity and pH level increased. Only Na + content in the leaves responded positively to increment in Salinity and pH level. Conclusion: Based on results, Salinity reduced plant height as well as dry weight and increasing of Salinity and pH increased supply of Na+ in tomato leaf.
