| Summary, etc. | Results of the present investigations on the “performance evaluation of rubber under different planting intensities” are in agreement with the findings of earlier studies conducted in India and abroad. Individual tree growth parameters like girthing and bark thickness are affected by higher densities. Per tree yield and drc are higher at lower population densities. Yield of rubber is a function of the number of trees in tapping, the average yield per tree and the frequency of tapping. Hence per hectare yield will increase with increasing density upto a certain limit. However, the estimation of the optimum stand per hectare that will maximize profit over the whole productive period of the holding is rather difficult. This involves the difficult task of attempting to predict the future level of variables such as tapping costs, selling price of rubber etc. When rubber prices are high and when family labour is employed for tapping, higher yield per hectare realized from higher stands may be profitable. But when tapping cost is higher compared to price of rubber it is desireable to have higher per tree yield. In Malaysia, a stand of 750 trees/ha is recommended for small holders who work on their own estates. But in India such recommendations based on scientific budgeting are lacking. However, the experiment results point to the necessity for reviewing our present recommendations and a modification to allow for a higher stand for small holdings in which family labour can be employed. The salient findings of the study are as follows: Girth increment was higher in low density planting and vice versa. Thickness of virgin bark decreased with increasing density. Leaf area was more at wider spacings. Volume of latex/tree/tap was less at higher stands. The drc was found to decrease with denser plantings. Per hectare yield was more at closer spacings. Sunlight penetration through the canopy was more in stands with wider spacings. |
