Abstract

A pot culture experiment was conducted on jute (Corchoros oli(orius L.) grown in
Lateritic soil of Panagrah during 1993 and 1994 to study the effect of K and Zn application on.
dry matter production and their uptake by jute crop fibre and wood. Application of K and Zn
increased the total dry matter, bark (fibre) and wood up to 40 mg K kg'1 and 5 mg Zn kg:1
levels respectively. Total K uptake increased significantly with the application ·of K and Zn
individually. Uptake of K by both b'ark and wood was also significant due to application of K
alone. But the effect of Zn alone and K x Zn interaction on fibre and wood did not show any
significant results. However, Zn uptake by the whole plant increased significantly due to
application of all levels of K and Zinc upto 5 mg kg,1 respectively. With the increasing level of
potassium, zinc absorption increased significantly with significant decrease in K/Zn ratio of
the whoie plant.
