Abstract

Methodology: One-year-old bitter olive seedlings were obtained from Qorogh nursery in Golestan province. For this purpose, 1000 rooted seedlings were prepared and 360 seedlings with equal collar diameter, height and root length were selected. Suitable soil was prepared and screened from Bandar Turkmen region of Golestan province. Seedlings were planted in a size seven flower pot (exact size of opening: 23 cm and exact size of height: 21.5 cm) in the middle of March. After applying fertilizer and superabsorbent (0, 25, 50 and 75 g), the irrigation period was carried out in three periods of 5, 10 and 15 days once for 140 days.
Background and objectives: Drought is one of the natural disasters that affects the social, economic and environmental conditions of any country. Many efforts are made in the early stages of establishment and growth of seedlings, in order to increase their resistance against environmental stresses, so that the success of tree planting projects increases. How to increase the irrigation period and reduce its costs is one of the aim of the researchers of this fields. In recent years, plantation projects have grown a lot due to their environmental and socio-economic importance, and they are presented as a construction and development activity at the international level, and high technology is used in this field. Various methods have been tested, such as the use of superabsorbent treatments and Herban fertilizers, which somehow reduce the negative effects of drought stress. The aim of this study is to investigate the effect
