Effects of growth regulators on mineral nutrition of soybean

Abstract

This research deals with the effects of exogenous growth regulators on mineral nutrition of soybean plant (Glycine max cv. Davis). Under greenhouse conditions (2-chloroethyl) trimethylammonium chloride (CCC) 2,000 ppm, succinic acid-2,2-dimethylhydrazide (SADH) 4,000 ppm, gibberellic acid (GA) 100 ppm, and indolylacetic acid (IAA) 100 ppm were applied. Treatment with CCC demonstrated an increase in potassium level in the stems. SADH increased the levels of potassium in leaves and stems, and magnesium in leaves of soybean. GA increased the levels of potassium in leaves and stems, and sulfur in leaves, promoting e reduction of calcium and magnesium levels in soybean sterns. Treatment with IAA reduced the nitrogen, calcium, and magnesium levels in plant stems.
