บทคัดย่อ (EN): Soil fertility and the response of rubber yield to changes in soil nutrient contents are the key determinant of fertilizer management. However, yield response of rubber tree at different tapping stages to individual nutritional elements on a basaltic soil in eastern south of Vietnam is little known. In the current study, GIS spatial analysis technique was used to examine rubber yield in conjunction with soil nutrient contents in Cam my rubber plantation, eastern south of Vietnam. Soil samples and latex yield were randomly taken from 4192 ha of the plantation. Latex yield of the middle group, tapping ages from 4 to 9 years, highly responded to soil organic carbon (SOC), total nitrogen (Ntt), total phosphorus (Ptt), total potassium (Ktt), available P (Pavai) and exchangeable potassium (Kex), while yield of the mature group, tapping ages from 10-20 years, significantly responded to SOC, Ntt, Ptt and Pavai. For both groups, all those nutritional elements, except Ktt and Kex for rubber in middle group, however, were in adequate or high levels of contents. For rubber trees in middle group, about 1390 ha (33 %) and 1475 ha (35%) out of total 4192 ha in the plantation were deficient in Ktt and Kex, respectively. The response to increasing soil nutrient content of middle group was greater than that of the mature group, suggesting that nutrient demands of the young tapped trees were higher than those of the old tapped trees.
