Effect of the Economic Benefit of Ethrel-Palm Oil Mixture and the Conservation Period of the Stimulating Paste on the Rubber Productivity of Hevea brasiliensis in the Efficient Management of Plantation Stimulation in the South-East of Côte d'Ivoire| Chapter 2 | Research Highlights in Agricultural Sciences Vol. 5

 To sustainably claim and/or increase natural rubber output, without risk of overstimulation, of a set of narrow plantations of Hevea brasiliensis, efficient administration of hormonal stimulation of elastic production becomes unavoidable. This must be controlled from a stimulation readiness and distribution centre. A study was then conducted to determine the type of exciting paste prepared and the ending of maximum effectiveness concerning this paste in the south-oriental of Côte d'Ivoire, for two years from 2012 to 2014. The study was attended on the GT 1 clone, according to the one timber plot design of 15 treatments of 30 trees recurring per treatment, matching to different conservation periods of the exciting paste prepared. Two impetus products, that is to say Ethrel mixed with palm lubricate and Almephon (ready to use), were kept at range temperature and left to cool. The processed stimulating paste was stocked for 0, 3, 7, 14, 21, 28, 42 and 56 days. The results indicated that the elastic yield, radial vegetative progress, physiological description and health of the rubber wood were not affected by both the preservation of the stimulating glue and the different conservation periods. However, the exciting pastes prepared could be stocked for up to 56 days, two together at room temperature and in the cold, outside losing their influence. The physiological profile and fitness of the rubber trees were not as overwhelmed by the preservation of the stimulating paste and the various conservation times. These main results make it attainable to predict the management of hormonal provocation of rubber result, without electrical capacity, from centers that will ensure preparation and allocation to the differents plantations. We decide that the significantly cheaper Ethrel drug paste mixed with touch oil and utilizing palm oil, an main local product and in consideration of the bark of Hevea brasiliensis, would be the best choice.
