An experiment was conducted incorporating three systems viz. 1/2 S d/1, 1/2 S d/2 and 1/2 S d/3 with three periods of tapping rests based on minimum temperatures of 20-20 oC, 15-15 oC and 10-10 oC and compared with a control. Though the 1/2 S d/1 system for all the combinations showed a high annual yield, the occurrence of tapping panel dryness (TPD) was found to be relatively high. The 15-15 oC rest covers around 20 per cent of the peak yields in comparison with the continuous tapping systems. Analysis of yield showed a high significant relation between the sub-plot treatments of the temperature regimes. Mean yield was high (30.8 gm/tree/tap) for the continuous system of 1/2 S d/3 tapping system which also registered the same in the 20-20 oC rest. With a low incidence of TPD (5;), the 15-15 oC minimum temperature regime, for the 1/2 S d/2 system of tapping, in general, showed an optimum system for exploitation of latex yield during cold season under this non-traditional agroclimatic condition of latex yield during cold season under this non-traditional agroclimatic condition. Neverthless, basic knowledge of the effects of rest periods during the cold season with an optimum system of tapping, coupled with a lack of long term deleterious effects, would necessarily render exploitation methods to tackle and overcome several prevailing limitations in the region.
