บทคัดย่อ (EN): The effect of planting density in rubber (Hevea brasiliensis) was studies in an experiment conducted with three densities viz.420, 620, 824 trees/ha. It was observed that lower density had higher percentage of trees ready for tapping during initial years, due to higher growth. However higher density achieved required girth in subsequent years. In spite of decrease in plant number over the years, the highest density had always lower girth even 24 years after planting. Higher density also had higher percentage of runs. The higher plant densities produced taller plants, increased crotch height and decreased the number of branches. Plant density affected yield per tree and yield per unit area. Yield per hectare increased with increase in plant density during initial years, however this declined later. High yield per tree per tap was observed in the lowest density with lower yield per unit area. Yield increased in all densities with application of stimulant. Percentage of yield increase due to application of stimulant was higher (40%) in medium density (620 trees/ha) compared to other densities. Percentage of wind damage was lower in higher density during initial years. The volumetric yield of Hevea logs as varied with density. Total timber volume per hectare was high in high density and lower per tree volume of log compared to lower density. Maintaining a density of 600 trees per hectare appears to be most suitable for North Eastern region of India.
