Comparison of compatibility of different atriplex species under different irrigation periods

In order to find out plants which are suitable for rehabilitation of deteriorated rangelands of Persian Gulf and Oman sea {Hormozgan province) an experiment was carried out in Sarkhoon fourty kilometres far from north of the Bandarabbas with Annual rainfall of approximately 170 mm. The layout of this experiment was a split plot design with six irrigation period as main factors and three atriplex species. Irrigation treatments were as follows: A: Only onetime has been irrigated, B: irrigation every 10 days C: Irrigation every 20 days, D: irrigation every 30 days. E: Irrigation every fourty days, F: irrigation every 60 days. Different atriplex species were as follows: a: Atripex lentiformis b: Atripex halimus c: Atripexcanescens. According to statistical analysis of the first year there is significant difference at the level of five and one percent between different species and irrigation treatments. Seedling death percent of species were recorded for four years but survival of different irrigation periods were few. So results of this experiment were not analysed at the end of experiment course.
