Sugarcane COS 767 was grown in refined sand with deficiency levels of N (0.12 mM), P (0.015 mM), K (0.04 mM), Ca (0.04 mM), Mg (0.02 mM) or S (0.02 mM). The visible symptoms of N deficiency appeared first and those of Mg last. In N-deficient plants the lowest 2 pairs of leaves turned pale yellow from the base of the lamina. The discoloration then gradually spread upward to cover the entire length of the leaf.
