Studies on the Effect of Nitrogen and Phosphorus on the Growth, Development and Flowering of Chrysanthemum CV. Yellow (Chrysanthemum Indicum Linn). III Nutrient Uptake

Abstract

Investigations were undertaken to study the pattern of uptake of N, P and K by Chrysanthemum indicum) CV. Yellow in the field as influenced by their application, at different levels. The trend of uptake of N, P and K was similar. There was high uptake at pre-bloom stage and a gradual but slight increase there after. The major nutrients were stored in pre-bloom stage at a high level to be utilised for the subsequent deve- ment and production of chrysanthemum flowers. The uptake of Ca and Mg was higher at the flowering and post-bloom stages.
