“…Thus, given the presented results and in agreement with the literature, the use of low-and high-salinity water simultaneously, with split-root system, can be a viable alternative for the conditions in which the rural producer has availability of both sources of water, especially in protected cultivation using substrate maintained in containers (Guedes et al, 2015), or in hydroponics (Mulholland et al, 2002).…”

A B S T R A C TThe objective of this study was to evaluate the use of saline water to grow cucumbers cultivated in substrate composed of coconut fiber and washed fine sand (1:1) and submitted to splitroot system. The experimental design was completely randomized, with eight treatments and four replicates. Treatments consisted of different fertigation managements, comprising two nutrient solutions of different electrical conductivities (1.65 and 6.25 dS m -1 ), applied in a continuous or alternated way, with splitting or not of the root system (S/S). Growth and yield variables were evaluated. The use of water with electrical conductivity of 6.25 dS m -1 to prepare the nutrient solution caused significant reduction in all variables of cucumber growth and production. Adoption of split-root system with simultaneous application of the two water types increased cucumber tolerance to salinity.Estratégias de fertirrigação com água salina na cultura do pepino em ambiente protegido R E S U M O O objetivo deste trabalho foi avaliar o uso de água salina na cultura do pepineiro cultivado com substrato composto por fibra de coco e areia fina lavada (1:1) utilizando o método de divisão do sistema radicular.

“…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). Salinity affects plant growth by weakening the plant's abity to absorb water from the bed it ves in.…”

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.

Tomato plants were grown using a nutrient film technique in a hydroponic system to evaluate the effects of starting time and duration of salinity treatment and the interaction between salinity and planting density on fruit yield and quality. The electrical conductivity (EC) of the nutrient solution was maintained until the anthesis of plants. Sodium chloride was added to the standard nutrient solution until EC 8.0 dS·m −1 and this level was maintained from the anthesis of the first flower truss until the fruit harvest (whole treatment); 8.0 dS·m −1 solution was applied from anthesis of the first truss until 20 days after anthesis (DAA) (early treatment) and from 20 DAA until the fruit harvest (late treatment). The average fruit weights in the whole, early, and late treatments were 46, 71, and 58% of the control weight, respectively. Fruit radius and cell size were also reduced under each salinity treatment; however, the estimated number of cells per fruit was not significantly affected by the salinity treatment. The levels of total soluble solids (Brix%) were 6.2 in the control and 9.9, 7.7, and 9.1 in the whole, early, and late treatments, respectively. Incidences of blossomend rot were 0, 33, 25, and 16% in the control, whole, early, and late treatments, respectively. The influence of planting density (8.5-9.5 plants/m 2 ) under saline conditions on fruit size and sugar content was not considerable unremarkable. The fruit yield at high planting density increased more than that at a low plating density under salinity treatment.
