Resumo: | The present research originates from the demands of farming communities and Social Movements in the Cantuquiriguaçu Territory of Citizenship, in the central-west of the Brazilian state of Paraná. To support the use of Creole Maize (Zea mays) by such agents, this research is structured in two sections. The first section focuses on elaborating a bibliographic study about Creole Maize (Zea mays), Conservation Strategies, Sustainable Development Goals (SDGs) and the role of the Guardians of Creole Seeds, related to the Rede de Sementes da Agroecologia (ReSA, the Agroecology Seed Network) of the state of Paraná. In order to achieve it, qualitative and quantitative methodologys were used by means of a semi-structured questionnaire, which was applied to the above-mentioned elements from several municipalities of the state via online platform and telephone conversation. The collection and analysis of this data conveys how significant are the initiative of ReSA, the in situ, ex situ and on farm Conservation Strategies and the Creole Seeds events and fairs, and a geographical and cultural delimitation was found for some subspecies of corn, in the municipalities of Ponta Grossa-PR and Campo Largo-PR. The second section aims on analyzing, through a quantitative methodological approach, the nutritional and microbiological profiles as well as the ideal proportion of mixed silage of maize, Leucaena, Crotalaria and Guandu Beans at levels of 20%, 30% and 40%, and on evaluating the silos’ opening times: 0, 30 and 60 days. The analyzed nutritional and microbiological parameters suggest that the mixed silage of Creole maize with Leucaena, Crotalaria and Guandu Beans increases the fodder nutritional quality. |
