Interaction effect of potassium and zinc on the growth and uptake by jute (Corchorus outorius L.) in fine vertic ochraqualf soil
Abstract
A pot culture experiment was conducted on jute (Corchorus olitorius 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.
