บทคัดย่อ (EN): The RRIMFLOW System of Exploitation (RF) has been extensively adopted commercially on both basal virgin (B0-2) and high panels (H0) of various clones in several NR producing countries since it was first recommended for commercial adoption on trees above twelve years of age from planting in the mid-nineties. The RF short cut system is widely accepted as the ideal system to maximize tree, tapper and land productivity in rubber as well documented in several publications. It is however not widely known in the industry that the RF system is equally effective on renewed bark (panel B1-1) provided it is of good quality and sufficient thickness. This paper assesses the performance of the RF short cut system on renewed bark based on data collated from commercial task size evaluation and large scale commercial adoption and determines it’s suitability for wider commercial adoption on panel B1-1. Data presented has confirmed that the yield responses obtained on renewed panel B1-1 tapped on the RF short cut system are far superior to that of conventionally tapped trees irrespective of clones. This was true for all three parameters of yield namely tree, tapper and land productivity. These yield responses on panel B1-1 exploited on the RF system are comparable if not better than that obtained on panels B0-2 or H0-1. The positive yields obtained from RF exploitation of panel B1-1 also recorded in trees of PBIG-GG2 seedlings tapped on double cuts on panel H0-1 & B1-1. Trees of four clones previously exploited on panel B0-2 on the RF system for periods of 3 to 5 years registered marked increase in yield productivity when the panel was changed over to panel B1-1. The data strongly suggests that RF exploitation of renewed panel B1-1 of most clones is profitable and economically viable. It is also apparent from the data that high yield productivity obtained on the RF system can be sustained over the long term by panel changeover and that renewed bark of panel B1-1 can withstand RF exploitation based on stable DRC values recorded over the long term. This paper will remove the misleading perception in the industry that the RF system of exploitation is only good for basal panel B0-2 or high panels (H0-1 to H0-4) and not very suitable for adoption on renewed panel B1-1. The RF system of exploitation (1/4s d/3 + gaseous stimulation) is strongly recommended for large scale commercial adoption on renewed panel B1-1 to maximize yield productivity and prolong the economic life of the rubber tree, particularly in view of the prevailing high selling prices of rubber.
