Sand tailings derived from tin post-minings activities have high porosity, low water holding capacity, and low organic matter content.  These conditions causes soil water deficit, especially in dry season. To increase the successful of  sand tailings revegetation  with rubber tree,  it is important to select some rubber tree clones based on their adaptability on the sand  tailings conditions, especially drought stress. This research aimed to study the response of several rubber tree clones to the frequency of watering on sand tailings. The experiment was conducted in a plastic house at the experimental station of Agrotechnology  Study Program of Bangka Belitung University, Sungailiat for 4 months. The experimental design  was a factorial randomized block design with two factors and three replications. The first factor was the frequency of watering (every day, every 3 days, and every 5 days), the second factor was a combination of recommended rootstock clones and recommended latex clones (clone GT 1 + PB 260, GT 1 + IRR 118, and PB 260 + BPM 24). The results showed that watering every 5 days caused  drought stress resulted in impaired  growth of rubber  in sand tailings media derived from tin post-mining.  The combination of rootstocks and scions PB  260 + BPM 24 and PB 260 + IRR118 were categorized as moderately tolerant clones while GT 1 + PB 260 was categorized as sensitive clones to drought stress in the  sand tailings media.   Keywords: drought tolerance, watering frequency, rubber tree clones, sand tailings
