Influência do plantio de manivas em posição vertical e horizontal na produtividade de raízes de três cultivares de mandioca

Abstract

Cassava (Manihot esculenta Crantz) is a crop of great economic, social, and food importance in Brazil, standing out for its wide adaptability to different cultivation conditions and its fundamental role in family farming. This study aimed to evaluate the influence of cassava stem cutting (maniva) planting position on the development and productivity of the cassava cultivars BRS 1668, BRS Dourada, and BRS Kiriris. The research was conducted through the monitoring of an experiment carried out by Embrapa Rondônia, using vertical and horizontal planting systems. Characteristics related to vegetative growth and plant productivity were evaluated, including plant height, number of large and small roots, and root mass. Data were obtained through field measurements, root counting, and sample weighing using an electronic scale. The results showed that the cultivar BRS 1668 presented similar performance under both planting systems. The cultivars BRS Dourada and BRS Kiriris showed better performance under horizontal planting, with greater plant height and root yield. Among the evaluated cultivars, BRS Kiriris stood out by presenting the highest values for vegetative growth and productivity. It was concluded that both planting systems are suitable for cassava cultivation; however, horizontal planting provided productive advantages for some cultivars and greater practicality for farmers.
