Effects of Water Ozonated and Salinity on Some Properties of Cucumber

Abstract

A B S T R A C TThe main objective of this study was to investigate the effects of water ozonated and salinity on some properties of cucumber. The treatments were defined by a two-factorial design of three water ozonated (0, 0.5 and 1 mg L -1 ) and three water salinity levels (2, 4 and 6 dS mG 1 ). A greenhouse experiment was conducted and after germination, cucumber seeds were grown in pots containing soil, coco peat and perlite and were imposed with water ozonated and salinity treatments. The fruit yield, plant height, stem diameter, total soluble solids and some elements were determined. The results showed that salinity of irrigation water significantly reduced fruit yield and plant height of cucumber. However, statistical testing showed significant increase in total soluble solids with increasing water salinity. Ozonated water increased fruit yield, especially in water salinity 2 dS mG 1 . Also, application of ozonated water caused significantly increases in the plant height. The results also indicated that salinity and ozonated water reduced stem diameter of cucumber, although there were not significant differences. The highest fruit yield (22.76 kg mG 2 ) and plant height (137.2 cm) were obtained at the third level of ozonated water (1 ppm) and 2 dS mG 1 of salinity level. Statistical testing indicated significant increase in concentration of P and Na with increasing water salinity. The application of ozonated water and water salinity caused decreases in concentration of NH 4 . The highest concentration of P (0.41%) and Na (2.76%) were obtained at the third level of ozonated water (1 ppm) and 6 dS mG 1 of salinity level.

Strategies of fertigation with saline water for growing cucumber in a greenhouse

“…Salinity effect on cucumber stem diameter has been little studied, but the few reports demonstrate that under salt stress conditions the plants show reduction of this variable (Santana et al, 2010;Peykanpour et al, 2015).…”
