The Brazilian livestock production is pasture-based, requiring more technologies that allow to increase productivity with efficiency. This study aimed to evaluate the agronomic performance of tropical grasses. The experiment was carried out at Embrapa Agrossilvipastoril in Sinop-MT from mar/2015 to mar/2016. The experiment was a randomized complete block design with three treatments and three replications (24 m2). The treatments were cultivars: Guara (Paspalum regnellii cv. BRS Guara), Tupi (Brachiaria humidicola cv. Tupi) and Marandu (Brachiaria brizantha cv. Marandu). Pastures were fertilized with 80, 140 and 140 kg ha-1.year of N, P and K, respectively. In each cycle, forage mass (FM) was quantified by clipping two quadrat samples (0.5 by 1 m) per plot at 12 cm height. The fixed rest period was used as harvest strategy, allowing 28 or 42 days, in the rainy or dry season, respectively. Data were analysed using the mixed model method with a special parametric structure in the covariance matrix, through the MIXED procedure of SAS. Treatments means was estimated using ?LSMEANS? and ?PDIFF? was used to analyze means. Significance was detected at the 0.05 level of probability. There was a significant interaction between cultivar x season for forage accumulation (FA) (P<0.01) and forage accumulation rate (FAR) (P<0.05). Guará showed higher FA and FAR (P<0.05) in autumn and summer (5,280; 5,390 kg ha-1; 56.8, 64.1 kg ha-1.d), followed by spring (3,240 kg ha-1, 35.9 kg ha-1.d) and lower in winter (216 kg ha-1, 2.2 kg ha-1.d). Tupi showed higher FA (P<0.05) in summer (5,260), followed by spring (3,800) and less to autumn (2,920), and during winter there is no FA. Similar responses for FAR (62.6, 42.3 and 31.3 kg ha-1.d, respectively). Marandu provided greater FA (P<0.05) in the summer (4,870 kg ha-1), with similar values between autumn and spring (4,260 and 3,740 kg ha-1) and lower for winter (151 kg ha-1). The highest rates were measured in summer, followed by autumn and spring and lower in winter (57.9; 45.8; 41.5 and 1.6 kg ha-1.d, respectively). Comparing the three cultivars in the seasons, the FA varied only in autumn (P<0.05), when Guara was the most productivity, with 23% and 80% more forage produced than Maradu and Tupi, respectively. Guara has potential of production similar to Marandu, excepted during the autumn when was better. Guara can be an alternative as a forage grass in the Brazilian livestock production.
