This project aimed to evaluate the agro-botanical performance of gramalote (Axonopus scoparius), subjected to three different treatments of a fertilizer composed of urea plus cuyasa. This project was developed under a randomized block design, and analyzed through the statistical package InfoStat with Tukey's test at 0.05 significance. Four treatments with five replications were used; the incorporation of the guinea pig was 0% (T0), 100% (T1), 75% (T2) and 25% (T3), adding a standard base of urea (0.125 kg/Ha) and lime (4.55 kg/Ha). At the end of the statistical analysis, T1 was the best; in plant height, 124 cm were obtained at 90 days; in the number of leaves with 8, in the production of green matter and dry matter with 16.6 and 2.84 T/Ha respectively, in protein with 0.21 T/Ha, in the production of neutral detergent fiber 1.26 T/Ha was obtained, in acid detergent fiber 0.94 T/Ha was obtained, and in acid detergent lignin 0.12 T/Ha, This could have been produced by greater availability of vegetative material to provide nutrients to the crop for a longer time, supporting the washing by the rains, and making up for the low availability of natural soil nutrients that do not allow a good crop production under natural conditions. It is concluded that the application of fertilizers is productive in this pasture because they allow better development of the crop, as well as to increase the quality of the pasture, so it is recommended the use of this material as fertilizer for the crop, at the levels evaluated in this work.
