Experiments were conducted in 1985 and 1986 to study the removal of nitrogen, phosphorus and potassium by three varieties of Corchorus capsularis namely CVL-1, CVE-3 and CC-45. The nutrient levels comprised of 0-0-0, 45-5-18 and 67-10-28 kg nitrogen, phosphorus and potassium (N, P, K)/ha respectively. Nitrogen and phosphorus removal were highest with CC-45 compared to CVL-1 and CVE-3 in both the years. Potassium removal was higher with CVL-1 in both the years compared to the other two cultivars. Total accumulation of nitrogen was more in leaves than that of bark and stick. Total content of phosphorus and potassium was higher in bark. The trend of removal and accumulation of N, P and K increased with the increased rates of N, P and K fertilizer application.
