Abstract
The study results conducted over 20 years on the acclimatization and viability of jujube (Ziziphus jujuba Mill.) in the arid conditions of the Astrakhan Trans-Volga region and the Volga-Akhtuba floodplain are presented. The possibility of growing a multipurpose promising subtropical plant in this arid region is shown. It has been established that in the first year after planting, the survival of a crop without irrigation in semi-desert conditions is 4 times lower than with irrigation which makes up 25 %. Strong frosting of jujube does not cause the plant death. With a well-developed root system, the aerial part is completely restored and the reproductive capacity is restored in the same year. It was revealed that with growth and acclimatization, fruiting becomes more abundant and amounts to 10 kg per tree.
