This research is to know the relations of continous light to rubber plants’ productivity, located in West Tanjung Jabung, Jambi. This is an uncontrolled research with research spots taken at 225 m, 275 m, 325 m, 375 m, 425 m, 475 m, 525 m, 600 m, 700 m, and 800 m distances from flare. There are four rubber plants taken on each spots and flare is the light source researched. The variables observed on this research are rubbers production, light (illuminations, irradiations, UV, and quantum) splitted to day observation to the sunlight and night observation to the flare light. Other observation done on this research are weeds’ vegetation analysis, soil and air temperature observation, and soil analysis. Results on this research is the increase of contionus flare has no impact to the rubber plants productivity, because the observe value on the night observations show that illumination value is about 0,001-0,004 watt/m2, but the value of UV, irradiations and quantum shows zero point. Productivity of rubber plant is affected by the age of the plant and klon used as a seed, no treatment, no weeds’ control, and soil structure.The most influential factors in the production rubber clones GT and AVROS is the nutrient content of the soil, soil texture, soil pH, the amount of weeds, and the growth of rubber trees. In clone LCB factors affecting production are soil nutrient content, soil texture, soil pH, the amount of weeds, and the growth of rubber trees.
