In a randomized complete block design with three replications, the effect of using four types of foliar fertilizers (12-8-16+3, 16-32-16, 20-20-20 and urea) on dry season on the nutritional quality and yield of Brachiaria brizantha cv Paiaguás grass. Four cuts were made with intervals of 30 days. There was a significant effect (P < 0.05) on the height of the plants during the period studied as well as on the different foliar treatments that were applied in the work. The height of the plants decreased as the dry season (summer) progressed. The greatest response to foliar fertilization was reflected in the 16-32-16, Urea, Witness and 12-8-16+3 treatments with average plant heights of 39.29, 38.52 and 38.38 and 37.90 centimeters, respectively. The coverage in the cuts decreased as the summer progressed, obtaining the highest percentage with the Urea foliar treatment. The analysis of variance for the dry matter yield variable indicated that there were no significant differences (P >0.05) between the foliar fertilizers studied. However, there were significant differences between the cuts made in the study (P < 0.05). Crude protein decreased throughout the cuts made. The urea-based foliar treatment was the one with the highest crude protein content (8.82%) in the investigation. The crude fiber contents obtained in foliar fertilizers are considered as regular percentages. Foliar fertilizers presented low levels in terms of calcium percentages with percentages between 0.21 to 0.23%.
