The purpose of this research was to study the irrigation period to plant growth. The statistic design was split plot method. To done this research prepare hold dig to deep and diameter 130 and 80 centimeter, respectively and experimented three factors, irrigation period (70 and 90% depletion soil water), soil (modify soil and control soil) and plant (Tamarix and Eucalyptus). This research done with split plat method with 8 treatments and 4 replications.
The results show that the irrigation period, soil and plant had effective on plants high in first year, but other parameters had no role. Irrigation period and plant were effective on plant high in 5% level and irrigation period, while the other parameters had no effective on this factor in second year.
Combine analysis show that the irrigation period, year and soil, irrigation period and plant kind had significant effects on plants on (1%) level. The research shows that the Eucalyptus and Tamarix grow with supply litter water in 70 depletion soil water 0.24 and 0.19 cm, respectively. While, this plants were grow in 90 depletion soil water period 0.11 and 014 cm, respectively. Therefore, the 70 depletion soil water period and modify soil were better than 90 depletion soil water period.
