บทคัดย่อ (EN): Every crops in the world need suitable soil and climate conditions for optimizing its grow. According to soil plant relationship, there are close relationship between soil suitability and rainfall factor. Even though the influence of rainfall on plant production is closely related to the rainfall spread and soil type, but in general rainfall has close relation with production. Rubber tree (Hevea brasiliensis) is an indigenous tropical rain forest plant in the Amazon Basin, grows at an altitude of 200 m above sea level and near the equator. This region is characterised by monthly mean temperature between 24 and 28 ºC, with ample rainfall of annual totals amounting to 1500-2500 mm including some dry spells. So far the land quality related to rubber productivity is still based on qualitative methods. Quantitative research to predict relations between rubber production and clone potential, soil, and climate is still rare. The aim of this research was to make modelling of rubber tree production based on clone potential productivity, climate (rainfall, rainy day, altitude, and dry season) and soil (clay fraction, internal drainage). The assumption of all regression that have been used was fitted line plot based on regression quadratic type model. The result showed that the average optimum values for rubber production were as follows: rainfall 2640 mm/year, 133 rainy day/year, 3 month/year, and 168 m above sea level, 55 % of clay fraction, and 3 (internal drainage classes based on USDA Hand Book). This result showed that mathematic equation could be used to predict rubber production in specific area with 79.95 % of accurate level.
