Kieserite is a readily available fertilizer. Magnesium is widely used by plants for their reproductive development. Sulfur plays a fundamental role in the formation of the vegetative part and in the fruiting. The objective of this study was to evaluate the application of Kieserita on soil chemical attributes and on vegetative, nutritional development and quality of orange fruits. The experimental design was randomized blocks, and the treatments consisted of the doses of Kieserita (0, 280, 560, 840 and 1120 g plant-1) split in two applications with three replications. Kieserita provided improvements in the physicochemical qualities of fruits and soil chemical attributes at 6 (pH, Mg, CTC) and 12 months (P and K). In the plant the leaf contents of Mg and S increased with the doses of kieserita. Under the edaphoclimatic conditions of orange cultivation the maximum efficiency dose ranged from 560 to 840 g plant-1.
