Abstract: In the southern region of the State of Minas Gerais, Brazil, there is predominance of small farms that cultivate potato and exploit and dairy farming in family business form. These firms are important for the economic activity in the region, although most pasture areas are degraded. In Potato cultivation the intensive use of the area predominates with more than one crop per year, with absence of: technology, conservation and environmental techniques and crop rotation. This predatory system has led to the degradation of soils and natural resources. The purpose of this paper was to propose and disseminate techniques for crop managing and, mainly, the adoption of the crop-livestock integration system with potato as the main crop, providing for family business rationality and sustainable exploitation of its property. These practices can improve the income producers, and ensure the permanence in their properties. The research was carried out in three municipalities in the southern region of the state of Minas Gerais, prioritizing the sequence of rotational occupation and planting time of the potato: a) potato (planting in October), maize + Brachiaria grass (direct grazing and silage), millet (grazing); b) potato (February planting), oats (cutting and grazing), corn (grain); c) potato (October planting), maize; occupational sequence of crop rotation performed respectively in three municipalities. After the crops in succession, the potato planting is again restarted. The results obtained allow us to conclude that the crop-livestock integration system adds positive effects of potato production to those of livestock production, with a great synergistic effect benefiting all these operations.
