Effect of the Stimulating Paste Conservation Period and Economic Benefit of Ethrel-Palm Oil Mixture in Rubber Tree Plantations in South-Eastern Côte d’Ivoire

S. Obouayeba, E. F. Soumahin, A. P. Obouayeba, C. B. Y. Adou, J. L. Essehi, G. J. O. Atsin & M. K. Okoma · Journal of Experimental Agriculture International · 2016

To maintain and increase sustainable productivity and natural rubber yield, the hormonal stimulation management of rubber yield should be controlled from operation centers. A study was conducted to determine the type of prepared stimulant paste and the maximum efficiency period o...

Agronomic Potential of Some Rubber Tree Clones (Hevea brasiliensis) of the Fast Metabolic Activity Class in the Absence of Hormonal Stimulation in Southwestern of Côte d’Ivoire

G. J. O. Atsin, E. F. Soumahin, T. H. Kouakou, A. E. A. Elabo, K. M. Okoma & S. Obouayeba · Journal of Experimental Agriculture International · 2016

Fast-metabolism clones of rubber tree (Hevea brasiliensis) are appreciated for their good agronomic performance with little hormonal stimulation, due to their high intrinsic metabolic activity. They are highly demanded and therefore exposed to a significant risk of overexploitati...

Agronomic Performance of Hevea brasiliensis Muell. Arg. Clone IRCA 331 Grown in Southwestern Côte d'Ivoire

A. E. A. Elabo, G. J. O. Atsin, E. F. Soumahin, K. M. Okoma, Y. M. Gnagne, A. C. Démange & S. Obouayeba · Asian Journal of Research in Agriculture and Forestry · 2019

In order to test the agronomic performance of the newly developed clones, a Large-Scale Clone Trial (LSCT) comprising Hevea brasiliensis clones GT 1, IRCA 202, IRCA 331, IRCA 707, PB 280 and PB 310 was established in southwestern Côte d'Ivoire. They were planted in completely ran...

Latex Harvesting Technologies Adapted to Clones IRCA18, IRCA 111, IRCA 130, PB 235 and PB 260 of Hevea brasiliensis (Rubber Tree) of the Class to Active Metabolism in South-Western Côte d’Ivoire

S. Obouayeba, M. Diarrassouba, E. F. Soumahin, J. L. Essehi, M. K. Okoma, C. B. Y. Adou & A. P. Obouayeba · Journal of Agriculture and Ecology Research International · 2016

The rubber production falls due to the tapping panel dryness that has always been a major concern in rubber cultivation. This problem is acute when it is about clones of the class to active metabolisms which are very sensitive to tapping panel dryness. In response, this study was...

Quantitative Assessment of the Agro-physiological Advantages of Upward Tapping in Relation to the Downward Tapping of the GT 1 and PB 260 Rubber Clones [Hevea brasiliensis, Muell. arg. (Euphorbiaceae)] in Southwest Côte d'Ivoire

A. P. Moro, B. Y. C. Adou, M. Diarrassouba, D. Konan, E. F. Soumahin, T. H. Kouakou & S. Obouayeba · Journal of Experimental Agriculture International · 2021

The downward tapping on virgin bark of the lower panel (BO) is immediately followed by the upward tapping on virgin bark of the upper panel (HO), consecutively. To determine the agro-physiological advantages of one tapping over another, a study of the downward and upward tapping...
