| ABSTRACT: Selenium (Se) fertilization in grazing to biofortification of animal products have been carried out in low Se soils. The objective of this study was to increase the Se content in the biomass of Brachiaria spp.with urea coated with Se. The experiment was performed in a typical Hapludox soil under greenhouse conditions. A completely randomized block design with four replicates in a factorial structure with two cuts and six Se doses (0, 10, 20, 40, 80, and 160gha-1) was used. The Brachiaria brizantha demonstrated the absence of changes in higher harmful doses without modifying the activity of glutathione peroxidase enzyme. We concluded that enrichment of Brachiaria brizantha with coated urea is obtained with 34.5gha-1of Se. |

| ABSTRACT The demand for environmentally sustainable agricultural production systems encouraged this study, which evaluated the productive aspects and nutritional status of 'Piatã' palisadegrass and productive aspects and bromatological composition of 'Marandu' palisadegrass fertilized with eggshell, replacing other sources of calcium. 'Piatã' palisadegrass was grown in the field, in a randomized block design, and 'Marandu' palisadegrass in pots, in a completely randomized design, both with eggshell doses equivalent to 0, 78, 156, 234, 312 and 390 kg ha-1 of total calcium, using four replicates. The productive aspects of 'Piatã' and 'Marandu' grasses were not significantly altered by the eggshell doses, as well as the contents and accumulations of N, P, K,... |
