EFFECT OF CALCIUM AND POTASSIUM FERTILIZERS ON CALCIUM AND POTASSIUM CONTENTS OF RICE SAPLINGS

Vandana and Raj Mittal

Abstract

A pot experiment on rice saplings was performed in which varying amounts of calcium and potassium fertilizer has been applied to the plants in a controlled environment. During the period of growth the rice saplings have been constantly monitored by observing their average length, colour and texture. It is observed that presently applied maximum amount of potassium fertilizer is favourable for plants and visually induces no adverse affect on the saplings, on the contrary the applied maximum amount of calcium fertilizer is not up to the optimum value. Potassium and calcium contents in the rice saplings have been determined using a XRF method. The potassium contents are found to increase with both calcium and potassium fertilizers whereas calcium contents are slightly suppressed at the intent of calcium fertilization and regained at the later stage. On the other hand calcium content in rice saplings is found to increase with KCI fertilizer. Water uptake of the rice saplings was also found to increase with the addition of fertilizers. The values of calcium and potassium contents also support the physically monitored growth of rice saplings in terms of their colour, average length and texture. Details of findings are discussed in this paper.
