บทคัดย่อ (EN): Panel changing is attempted in some plantations under the assumption that it helps to manage tapping panel dryness and increase yield. It is also considered to be useful for reducing the physiological stress generated in the panel due high frequency tapping. In a Randomised Block Design experiment, effect of panel change on long term yield response of Hevea brasiliensis (clone RRII 105) under different frequencies of tapping and stimulation was studied over a period of eleven years. There were eight treatments comprising of d2, d3 and d4 frequencies of tapping of half spiral cuts with and with out panel change and different levels of stimulation. Considerable yield variation was observed between various treatments over the years. Effect of panel change on yield increase was more prominent in the initial five years. No significant beneficial impact of panel change on yield increase was observed under different systems of tapping. Higher yield could be obtained under d2 and d3 frequencies of tapping with upper panel change (CUT). Comparable yield could be obtained under various frequencies of tapping. Cumulative yield observed within similar systems of tapping with or with out panel change were also comparable. Significantly high yield (gram/tree/tap and per tap yield) was noticed under d4 frequency of tapping. Highest cumulative yield was ob-served under d2 frequency of tapping which was however observed to be at par with d3 frequency of tapping with or without panel change. Panel change results in higher TPD under d/2 frequency of tapping compared to lower frequency of tapping. Moreover, Benefit of panel change is reflected only in the initial five years. Panel management after first five years of tapping is difficult. Hence, continuous panel change cannot be considered for managing TPD or to get sustainable high yield over long term.
