Abstract

Rice plants were grown in complete and deficient nutrient solutions, with respect to macronutrients. Growth was affected by lack of N, P and Mg only. The concentration of the elements in dry matter, however, was affected by the treatments. Both leaf analyses and quick tissue tests showed to be adequate to show variations in mineral composition in response to the omission of either N, P on K from the substrate. Foliar nitrate reductase activity decreased when any element, except Ca (increase) was lacking.
