Resumo: The objective of this work was to evaluate the effect of phosphate fertilization (0, 30, 60 and 120 kg of P2O5 ha-1) on forage production and morphogenetic and structural characteristics of Mesosetum chaseae under natural field conditions in the savannas of Roraima. Phosphate fertilization positively and significantly (P<0.05) affected green dry matter (GDM) production, absolute growth rate (AGR), number of tillers plant-1, number of leaves tiller-1 (NLT), average leaf size (ALS), leaf tiller area (LTA), appearance rates (LAR), expansion (LER) and leaf senescence rates. The maximum yields of GDM, AGR, LAR, LER, NLT, LTA and ALS were obtained with the application of 89.17; 112.7; 47.7; 51.9; 102.9; 101.8 and 94.8 kg of P2O5 ha-1, respectively. The efficiency of P utilization was inversely proportional to the P doses applied.

La fertilización con fosfato afectó positiva y significativamente (P<0,05) la producción de materia seca verde (MSV), la tasa de crecimiento absoluto, el número de macollas planta-1 (NMP), el número de hojas macollas-1 (NHM), el tamaño medio de la hoja (TMH), el área foliar macollas-1 (AFM), tasas de aparición (TAF), expansión (TEF) y senescencia foliar. Los rendimientos máximos de MSV, TAC, TAF, TEF, NHM, AFM y TMH se obtuvieron con la aplicación de 89,17; 112,7; 47,7; 51,9; 102,9; 101,8 y 94,8 kg de P2O5 ha-1, respectivamente.
