SUMMARY:

Cassava (Manihot esculenta Crantz) is a crop of great socioeconomic importance in Brazil, especially in the North region, where it plays a fundamental role in food security and income generation. Thus, the objective of this study was to evaluate the development of four cassava varieties (BRS Kiriris, BRS Poti, Jurara and BRS Formosa), in two planting systems (conventional and with windrows), for a 12-month cycle. The experiment was carried out at the Igarapé-Açu School Farm, in the municipality of Igarapé-Açu in the Northeast of Pará, in a randomized block design with subplots, with treatments in a 4x2 factorial (4 varieties x 2 planting methods). Biometric analyses included: plant growth index; leaf production index; stem diameter; number of emerging stems; root weight; seed cassava weight; and leaf weight. The evaluations were performed by periodic biometric analyses, at 30, 120, 150 and 180 days after planting. The statistical analysis was by the Tukey test, using the Statistical Analysis System (SAS, 2022) statistical package. The Jurará and BRS Kiriris varieties stood out in vegetative growth and productivity, and the planting system with windrows proved to be more efficient than the conventional one, favoring the development of the roots of the cassava plants.
