The nutrient status of soil and leaf in Abedin and Sons Rubber Garden, Fashiakhali, Chittagong Hill Tracts were studied to relate their effects on the growth of rubber plants. Total nitrogen, available phosphorus and potassium concentration of soil were 59.1 to 73.1 mg/100g, 0.86 to 1.19 mg/100g and 8.24 to 16.22 mg/100g and NPK of leaves from 2.23 to 3.24%, 0.22 to 0.45% and 1.28 to 1.65% respectively. Both DBH and bole height were significantly and positively correlated to soil and leaf NPK. Correlation between bole height and DBH was positively significant.
