摘要

Problem statement: This study was conducted to examine the effects of irrigation water pH and sanity on the growth and absorption of P, Na, Ca, K by tomato. Approach:The study includes two sanity 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 sanity 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). Sanity and pH treatments were adjusted with Nacl and H_2SO_4/N_2CO_3 salts respectively. Study of the effects of sanity 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 sanity and ph level increased. Only Na~+ content in the leaves responded positively to increment in sanity and ph level. Conclusion: Based on results, sanity reduced plant height as well as dry weight and increasing of Sanity and ph increased supply of Na+ in tomato leaf.
