This study aimed to evaluate possibility of the super absorbent polymer (SAP) to drought-resistant and growth of Taxus wallichiana Zucc and Pinus caribaea Morelet in nursery phase. The result indicated that with concentrations: 0, 0.2, 0.5, 0.7, 1.0% SAP for Taxus wallichiana Zucc and 0, 0.1, 0. 2, 0.5, 0.7% SAP for Pinus caribaea Morelet, the life period of trees is directly proportional to SAP added. The growth experiments, suitable concentration when non-irrigated and irrigated for 12-month-old Taxus wallichiana Zucc trees is 0.5% SAP with the highest shoot amounts and the shoot length (Shoot amounts: 8.8 and 19.1; shoot length: 3.99cm and 9.32cm); And 6 -monthold Pinus caribaea Morelet trees is 0.2% SAP with the highest length of new shoots (0.39cm and 3.01cm)
