บทคัดย่อ (EN): A density trial with combination of different dose of fertilizer was conducted with two popular clones viz. RRII 105 and RRII 118 at the Regional Research Station, Agartala with an objective to maximize the rubber yield per unit area of land. The density adopted were 420, 606 and 824 trees per hectare. Results showed that high growth of plant in low density and high yield per tree, but relatively low yield per hectare. The percentage of tappable trees was low due to poorer tree girth in high density during initial years. However, the number of tappable trees was higher which had resulted high yield per hectare. Percentage of wind damage was also low in high density. Response to high dose of fertilizer was not evident. Maintaining a tree density of 606/ha was appears to be reasonable. Reasonable number of tappable trees could be available in subsequent years in spite of loss of trees due to wind damage.
