إنجليزي. The effect of harvest period on the quality of storage roots and leaves of cassava cultivars was determined in an experiment carried out in a randomized complete block design with four replications in a split plot scheme, with five cultivars in the plots and ten harvest times in the subplots. The IAC 13 cultivar had the highest rate of dry matter accumulation in the storage roots and the Mico cultivar the lowest. The period of least dry matter content in the storage roots occurred later for the Fécula Branca, Mico and IAC 14 cultivars, and the minimum starch content in the storage roots occurred later for the Fécula Branca and Mico cultivars. In general, the IAC 13, IAC 14 and Fécula Branca cultivars had higher dry matter content in the storage roots, while higher starch content in the dry and fresh matter were obtained in the Fécula Branca cultivar. The crude protein content in the leaves decreased as the plant aged.

Com o objetivo de determinar o efeito de épocas de colheita na qualidade das raízes tuberosas e parte aérea de cultivares de mandioca, instalou-se um experimento delineado em blocos completos casualizados, em parcelas subdivididas, com quatro repetições, estando nas parcelas, cinco cultivares e, nas subparcelas, dez épocas de colheita. A cultivar IAC 13 apresentou maior taxa de acúmulo de massa seca nas raízes tuberosas, enquanto a Mico, a menor taxa. O período de menores teores de massa seca nas raízes tuberosas ocorreu mais tardiamente para Fécula Branca, Mico e IAC 14, sendo que os teores mínimos de amido na massa fresca das raízes tuberosas, foram mais tardios para Fécula Branca e Mico. Em geral, IAC 14, IAC 13 e Fécula Branca apresentaram maiores teores de massa seca nas raízes tuberosas, enquanto que maiores teores de amido na massa seca e na massa fresca foram obtidos por Fécula Branca. O teor de proteína bruta nas folhas decresceu com a idade das plantas.
