As noted in the history of Nova Friburgo-RJ since it s creation through the treaty between Dom João VI and the Swiss businessman Nicholas Gachet in 1818 for the implementation of the colony, the food production regarding the supplying Rio de Janeiro city s demand was prescribed. However, after the arrival of the first Swiss immigrants in 1819, due to problems of cultural adaptation, economic and environmental, the initial objectives of the colony were replaced by the need for survival of the settlers, which favored the cultural miscegenation between them and Portuguese s, indigenous and afroamericans, favoring the formation of a polycultural character of agriculture. During nearly two centuries of existence, the city witnessed the production of diversified food types in the so-called rural areas and in its urban center, where there are still present crops with partial subsistence purposes in productive backyards, notwithstanding they are pulverized in Nova Friburgo s landscape. In this work we will seek to analise the common characteristics between the crops of the enquired people, four of those living in the urban district and two in rural districts of Nova Friburgo, in order to analyze its relationship with the documented historical process, of polycultural agriculture subsistence emergence in the city. All managements have biodiverse character and polycultural in food production without the use of fire for fertilizing the soil neither of agrochemicals. Therefore, this paper aims to investigate the relationship of these productive areas, with agricultural practices historically evidenced in the municipality in order to verify the potential existence of a cultural link between the cases of the past and present. It is in this context between the present and the past, the new and the old, the internal and the external that the present research is proposed.
