Production of rubber in a certain locality is dependent on a number of biological environmental and technological factors. In this paper the effects of selected environmental and technological factors such as rainfall tapping days wintering improved tapping technique and yield stimulation on production in the RRIM Economic Laboratory at Kota Tinggi Johore Darul Takzim were studied. The data covered a twelve-year period. The analyses were done in two stages. In the first stage the effects of diurnal and monthly variations of rainfall on output were assessed; whereas in the second stage the Cobb-Douglas production model was used to measure the combined effects of environmental and technological factors on production. The findings showed (hat the wettest months were October to January which were also the highest yielding months and thus losses in potential crop due to rain interference in these months were substantial. The regression analysis showed that all variables used in the model except stimulation dummy were significant at P0.05. These variables explained approximately 62 of the total variation in the production of rubber in the RRIM Economic Laboratory.

Abstract

Production of rubber in a certain locality is dependent on a number of biological environmental and technological factors. In this paper the effects of selected environmental and technological factors such as rainfall tapping days wintering improved tapping technique and yield stimulation on production in the RRIM Economic Laboratory at Kota Tinggi Johore Darul Takzim were studied. The data covered a twelve-year period. The analyses were done in two stages. In the first stage the effects of diurnal and monthly variations of rainfall on output were assessed; whereas in the second stage the Cobb-Douglas production model was used to measure the combined effects of environmental and technological factors on production. The findings showed (hat the wettest months were October to January which were also the highest yielding months and thus losses in potential crop due to rain interference in these months were substantial. The regression analysis showed that all variables used in the model except stimulation dummy were significant at P0.05. These variables explained approximately 62 of the total variation in the production of rubber in the RRIM Economic Laboratory.
