Rubber cultivation faces the problem of scarcity of skilled tapping labour despite a significant reduction in the tapping intensity owing to latex harvesting technologies. Thus it is essential to optimise latex harvesting technologies by a greater reduction in the need for tapping labour. To achieve this a study was conducted on clone PB 260 of Hevea brasiliensis in Gagnoa in the centre west of C´te dIvoire. Low tapping frequencies (d4 d5 and d6) which are low consumers of tapping labour were compared to the standard (d3) system which is a high consumer of tapping labour. The results showed that low frequency tapping leads to yield losses per tree by four to 31 compared with standard tapping. These low yield losses however are compensated by the additional areas that these technologies are able to exploit. Furthermore low frequency tapping improves yield per tree and per tapping as well as the output of the tapper by 23 to 36 compared with standard tapping. In addition to that low frequency tapping systems have no significant negative impact on vegetative growth physiological profile and sensitivity to tapping panel dryness. Therefore these technologies can be adopted to remedy the shortage of tapping labour in rubber cultivation.

Abstract

Rubber cultivation faces the problem of scarcity of skilled tapping labour despite a significant reduction in the tapping intensity owing to latex harvesting technologies. Thus it is essential to optimise latex harvesting technologies by a greater reduction in the need for tapping labour. To achieve this a study was conducted on clone PB 260 of Hevea brasiliensis in Gagnoa in the centre west of C´te dIvoire. Low tapping frequencies (d4 d5 and d6) which are low consumers of tapping labour were compared to the standard (d3) system which is a high consumer of tapping labour. The results showed that low frequency tapping leads to yield losses per tree by four to 31 compared with standard tapping. These low yield losses however are compensated by the additional areas that these technologies are able to exploit. Furthermore low frequency tapping improves yield per tree and per tapping as well as the output of the tapper by 23 to 36 compared with standard tapping. In addition to that low frequency tapping systems have no significant negative impact on vegetative growth physiological profile and sensitivity to tapping panel dryness. Therefore these technologies can be adopted to remedy the shortage of tapping labour in rubber cultivation.
