DEFICIÊNCIAS MINERAIS NO CULTIVAR DE ALGODÃO IAC-22An experiment was set up in nutrient solutions, in order to describe the nutrient deficiency symptoms of cotton plants (Gossypium hirsutum L.) cultivar IAC 22. Plants were grown either in complete solution or solutions lacking one nutrient. The absence of N, P, K, Ca, Mg and B in the nutrient solution led to significant decreases in shoot dry matter. Root dry matter decreased in solutions lacking N, K, Ca, Mg and B, as well as in excess of Mn. Plants deficient for Fe and for Mo had less flowers and buds but an increased vegetative growth.
