Abstract

The effect of rate and interval of saline water application on yield, element
content of leaves and fruits as well as on soil characteristics were studied with
cucumber (Hybrid extram ) for two seasons under greenhous conditions. Cucumber
seedlings were grown in 20-liter pots filled with sandy loam soil containing 12% (v/v)
compost and irrigated firstly with fresh water and three weeks later with saline water
(EC::: 3.2 dS/m) in two rates, namely 100% of IR and 125% of IR within each irrigation
rate the plants were irrigated daily, every other day and every third day. The
cucumber fruits were collected and weighed regularly. The fruit yeild increased with
increasing irrigation rate but decreased in the second season within the lower
irrigation rate. An increase in yield with the increase of irrigation interval was also
Observed. Leaves and fruits analysis showed a dcrease in Na concentration with
increasing of irrigation rate. The soil analysis showed an increase in Na, CI, EC and
SAR values in the second season, wherase these parameters decreased with
increasing the rate of irrigation water for all treatments.
