Abstract

The physiological quality of seeds can be affected by the nutritional status of plants, with emphasis to sulfur supply, which is an essential component of amino acids. The research had as objective to evaluate the effects of side dressing sulfur fertilization on the physiological quality of bean seeds, cv. Pérola. The experimental design was the completely randomized block, with four replications. The treatments consisted of five side dressing sulfur doses (0, 20, 40, 60, and 80 kg ha^-1), in ammonium sulfate source, 22 days after seedling emergence. The physiological quality of bean seeds was evaluated right after harvest, by tests of germination and vigor. Side dressing sulfur fertilization increased seed vigor, as evaluated by the accelerated aging test; however, there was a decrease in initial seedling development due to the increase in the S dose until 50 to 60 kg ha^-1.
