Pasto Siambasa belongs to the grass family, more specifically to the species Panicum Maximum, with which we achieve an excellent relationship between production and quality.  It is an excellent alternative in both the agricultural and livestock sectors, as it combines great forage yield with excellent nutritional quality, reaching high protein values and excellent percentages of fiber, energy and digestibility.  

Another thing to take into account is its easy handling as we can pack in high temperature hours without losing quality due to falling leaves. Pasto Siambasa is a crop that has 80% leaf in its conformation, can be used for hay, silage or direct grazing.


Siambasa grass is a crop to be sown in spring with favourable conditions in temperature and luminosity for good germination.

The sowing dose is 10 kilos per hectare, given its low specific weight we have a large amount of seeds per kilo.   For this reason, the distribution of the seed is more uniform with a traditional seed drill.

We must obtain a very soft seed bed which will give us control over the planting depth of the crop, which must be greater than 2 centimeters.

Nutritional Quality

Pasto Siambasa is a crop that has 80% leaf in its conformation which makes it a crop of great palatability for all types of animals.

It offers a high quality nutritional table because it combines high percentages of protein, fiber, energy and digestibility. All the nutritional requirements necessary for an animal to produce meat or milk.

Siambasa grass is the forage of champions.
