Abstract

The leaf nitrogen concentration in the leaves of chrysanthemum CV. Yellow.de creased with the progressive development of the plant, while P and K increased slightly and then decreased. The Ca and Mg level increased with advancement of growth. The optimum N: K ratio to obtain good flower yield was assessed as 1:2 at pre-bloom and flowering stages of the plant growth.
