Resumo: The objective of this work was to compare herbage accumulation and canopy structural characteristics during the stockpiling period of the Marandu, Piatã, Xaraés, and Paiaguás cultivars of Urochloa brizantha. The experimental design was completely randomized, with three replicates. The experiment was repeated for two years (2017 and 2018), under mechanical cutting conditions, and the canopies were stockpiled for 90 days, from March to June. In the first year, forage mass was higher for the Xaraés and Paiaguás cultivars; however, in the second year, Xaraés showed a forage mass higher than that of the other cultivars. The number of vegetative tillers at the end of the stockpiling period was higher for Paiaguás, contrary to what was observed for number of reproductive tillers. The herbage accumulation rate was higher for the Paiaguás and Xaraés cultivars. The Paiaguás grass stands out for its high herbage accumulation rate during the stockpiling period and for its higher number of vegetative tillers and lower number of reproductive tillers than that of the other cultivars.

O delineamento experimental foi inteiramente casualizado, com três repetições. O experimento foi repetido por dois anos (2017 e 2018), sob condição de corte mecânico, e o dossel foi diferido por 90 dias, de março a junho. No primeiro ano, a massa de forragem foi maior para as cultivares Xaraés e Paiaguás; porém, no segundo ano, Xaraés apresentou massa de forragem maior do que a das demais cultivares. O número de perfilhos vegetativos no final do período de diferimento foi maior para Paiaguás, contrariamente ao que foi observado para número de perfilhos reprodutivos. Já a taxa de acúmulo de forragem foi maior para as cultivares Paiaguás e Xaraés. O capim Paiaguás se destaca por sua alta taxa de acúmulo de forragem durante o período de diferimento e por seu maior número de perfilhos vegetativos e menor número de perfilhos reprodutivos do que os das outras cultivares.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMembers of Grupo de Testes de Hipóteses em Forragens of Universidade Federal de UberlândiaMembros do Grupo de Testes de Hipóteses em Forragens of Universidade Federal de UberlândiaSantos, Manoel Eduardo RozalinoMoraes, Lucas Santos deFernandes, Flávio Henrique de OliveiraCarvalho, Bruno Humberto RezendeRocha, Gabriel de OliveiraAndrade, Carlos Mauricio Soares de2022-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26975Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02207Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e022071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/26975/14959Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26975Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
