| Sumario: | In Colombia, the specialized dairy systems are supported in forages use. However, edaphic and weather
features are related with production and compositional quality of grasses. In this sense, it is important to
recognize resilient fodder species to pastoral systems.
The objective was to evaluate the establishment (covert proportion (%, Cp) and adaptation grade
(0 to 3 scale, Ag) and production (dry matter yield (kg DM.ha-1, Dm) and net energy lactation (Mcal.kg DM-1
,
Nl) of five perennial ryegrasses (three diploid and two tetraploid) and three clovers (two reds and one
white) in two regions of Colombian highlands (Tuta and Mosquera at 2600 m.a.s.l.)
