Brazilian cattle breeding is based on the creation of beef animals and grazing milk, which demands a choice of cultivars adapted to different edaphoclimatic conditions, given the wide extent of Brazil. Thus, the objective of this study was to evaluate the gross production, production of green matter, accumulation rate and plant height of two tropical forages. For this, a field experiment was conducted, in a pasture area, located on a property in the municipality of Nova Maringá, State of Mato Grosso. The experiment was conducted by a randomized block design (DBC) with two treatments, namely: the cultivar Piatã (Urochloa brizantha) and the cultivar Zuri (Megathyrsus maximus) and 10 replicates, totaling 20 plots. The experimental unit was represented by a total area of ​​0.7 ha. The variables evaluated were gross production, production of green matter, rate of accumulation and plant height. Data collection was performed 100 days after the emergency. The grass of the genus Megathyrsus maximus cultivar Zuri, has great potential for productivity, and the cultivar Piatã, presented results not so satisfactory. However, each cultivar has its own characteristics, and behaves in different ways where they are cultivated.
