Resumo: The effect of potassium levels (0, 50, 100 and 200 kg of K2O ha-1) on green dry matter (GDM) yield and morphogenetic and structural characteristics of Mesosetum chaseae (Luces) was evaluated under natural field conditions. Potassium fertilization increased significantly (P<0.05) GDM yields, absolute growth rate (AGR), number of tillers/plant, number of leaves plant-1, medium blade length, leaf area, leaf senescence rate, leaf appearance and elongation rates. Maximum GDM yields, AGR, number of tillers/plant, number of leaves/tiller, leaf area and medium blade length were obtained with the application of 167.8; 156.2; 82.7; 101.6; 101.2 and 77.5 kg of K2O ha-1, respectively. The potassium efficiency utilization was inversely proportional to the increased potassium levels.

La fertilización potásica afectó positiva y significativamente (P<0.05) la producción de materia seca verde (MSV), tasa absoluta de crecimiento (TAC), número de macollas/planta, número de hojas/macollas, tamaño promedio de hojas, índice de área foliar y tasas de aparición, expansión y senescencia de hojas. Los rendimientos máximos de MSV, TAC, tasas de aparición y expansión de hojas, número de macollas planta-1, número de hojas macollas-1, índice de área foliar y tamaño promedio de hoja se obtuvieron con la aplicación de 167.8; 156,2; 82,7; 101,6; 101,2 y 77,5 kg de K2O ha-1, respectivamente. La eficiencia de utilización de potasio fue inversamente proporcional a las dosis aplicadas.O efeito de níveis de potássio (0, 50, 100 e 200 kg de K2O ha-1) sobre a produção de forragem e características morfogênicas e estruturais de Mesosetum chaseae (Luces) foi avaliado em condições de campo. A adubação potássica afetou positiva e significativamente (P<0,05) a produção de matéria seca verde (MSV), taxa absoluta de crescimento (TAC), número de perfilhos planta-1, número de folhas vivas perfilho-1, tamanho médio de folhas, índice de área foliar e taxas de aparecimento, expansão e senescência das folhas. Os máximos rendimentos de MSV, TAC, taxas de aparecimento e expansão foliar, número de perfilhos/planta, número de folhas/perfilho, área foliar e tamanho médio de folhas foram obtidos com a aplicação de 167,8; 156,2; 82,7; 101,6; 101,2 e 77,5 kg de K2O ha-1, respectivamente.
