The clone IRCA 111 of Hevea brasiliensis, produced in 1975, in Côte d'Ivoire, is one of the clones of the IRCA sets to promote in the rubber producing context. To this effect, the investigating, in the commercial plantations conditions are indispensable to define the optimal conditions of its exploitation in view of its popularization. For that to make, a survey of the agronomic behavior of the clone IRCA 111 is carried out since about ten years to the south-west of Côte d'Ivoire. This survey aims to determine the best of tapping systems allowing the IRCA 111 to express its agronomic performances better. The assessment of these performances is achieved by the application óf 6 tapping systems. The optimal exploitation of the IRCA 111's potentialities is given by the tapping system (d/3 6d/7 ET 2.5% 4/Y), tapping 2 times per week with 4 annual stimulations. For a possible shortage and/or dearness of tappers, the tapping weekly, stimulated 10 times per year, is the most suitable. The production of rubber per tree and per tapping (g/t/t) is in logarithmic relation with the intensity of tapping. The rate of tapping panel dryness (TPD) is bound also to the intensity of tapping by a polynomial relation of quadratic type. This survey shows that the IRCA 111 is altogether, a high producer, fast growth and fast or active metabolism clone.
