Agronomic performance of cassava cultivars in clay soil in central-western paraná

Abstract

Cassava (Manihot esculenta Crantz) is one of the main food crops in Brazil, used for both human consumption and industry. This study aimed to evaluate the agronomic performance of different cassava cultivars, intended for both table consumption and industrial use, grown in the municipality of Campo Mourão, Paraná. The experiment was conducted in a completely randomized block design with five cultivars (BRS 420, BRS 396, Gema de Ovo, Eucalyptus, Vitaminada) and four replicates. The variables analyzed were plant height, root diameter and length, and productivity. The analyzed variables were subjected to analysis of variance and compared by Tukey's test at 5% probability. The Formosa industrial cultivar showed the greatest mean height (1.77 m) and greatest root length (34.43 cm), suggesting good root development. The Eucalyptus cultivar stood out for its highest productivity (15,482.62 kg ha-1), differing significantly from the others. The other cultivars presented similar agronomic performance, highlighting the importance of management factors in maximizing productivity. The results indicate that cultivar selection should consider the intended use (table or industrial), as well as the region's soil and climate conditions and management practices of the region.
