Comportamento de variedades de mandioca indústria em ambiente de sequeiro na bacia do rio Pandeiros, Minas Gerais

Abstract

Cassava is cultivated in all Brazilian regions, with a great diversity of varieties, however, to ensure the profitability of the crop, the ideal choice of genetic material is a decisive factor, taking into account the edaphoclimatic conditions of the producing location. This work was carried out with the objective of evaluating how new varieties of industrial cassava behave in an upland environment, in the region of the Pandeiros river basin in the North of Minas Gerais. The experiment was carried out on the São Geraldo farm, owned by the Federal Institute of Education and Science and Technology of Northern Minas Gerais, Campus Januária, under dryland conditions. The characteristics of tuberous root yield, starch content, yield and flour yield were evaluated. The varieties BRS Kiriris and BRS Mani Branca had the highest averages of root yield, starch content, yield and flour yield, and can be considered varieties with high productive potential for flour and starch in the region of the Pandeiros river basin, in the North of Minas Gerais. The best harvest time was fourteen months after planting, as it provided the highest flour productivity, associated with higher flour yields, starch content and yield of tuberous roots.
