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.
