ABSTRACT: With the objective to determine the probable causes
of the appearance of abnormalities in BRS Topázio cotton plants, a greenhouse
experiment was carried out per subtraction, in which nutrients were omitted: N,
P, K, Ca, Mg and S, totalizing 21 experimental units. The omission of N, P, K
and Ca in the nutrient solution reduced the biometric characteristics of the
cotton crop, with K and Ca being the most affected by these characteristics. The
visual symptoms in cotton plants are seen with more severity in the lack of K,
P, K Ca and Mg elements. The omission of S did not affect the development of
the plants.
