Fertilization as simple procedure that is vital in enhancing latex production. The method used the injection and infusion approach as a green technological endeavor to fertilize mineral nutrients to boost latex production in rubber trees, which has involved injecting fertilizer straight into the trunk. As a result, it did not pollute the soil as an indicator of the employment of green technologies. The research was conducted from April to August 2015 in Perkebunan Nusantara VIII, West Java, Indonesia. The nutrient solution in various concentrations was applied by infusion or injection at the rubber trunk. The nutrient solution contained N, P, K, Ca, Mg, S, Fe, B, Cu, Zn, Mn, and Mo. The results showed that on lower 20 years old rubber increase of latex and dry rubber yield significantly in the trees that were given nutrient solution by injection without dilution of nutrient solution, and by infusion with the dilution of nutrient solution at 20 mL.L-1 and no applied nutrient solution. The heights of the infusion on the trunk at 50 cm from the ground with the dilution of nutrient solution at 10 mL.L-1 give the effect on the highest latex and dry rubber yield. Concentrate of 20 mL.L-1 nutrient solution in infusion application on the trunk of tapping panel dryness gives the effect on higher latex yield than normal rubber tree of the upper 20 years old
