Agronomic performance of sweet cassava cultivars

Abstract

Brazilian sweet cassava consumers are becoming more and more demanding in relation to sanitary conditions, organoleptic and nutritional characteristics of this vegetable products and their derivatives. Thus, more nutritious, early, productive, adapted to mechanized planting and good culinary quality sweet cassava cultivars were developed. This study aimed, therefore, to evaluate the performance of four sweet cassava cultivars in Uberaba, in Triângulo Mineiro region. The experiments were carried out in the experimental field of Faculdades Associadas de Uberaba (FAZU) during two harvest seasons. We adopted a randomized block design with three replicates, each plot consisting of four lines with ten plants. Trait averages were grouped by the Scott & Knott test. The results showed that cultivars BRS 399, BRS 397 and IAC 576-70 have potential to be grown in the region, since they showed root yield higher than 32 t ha-1 and up to 30-minute cooking time. BRS 399 stood out for its performance, showing root yield of 37 t ha-1 and 48 t ha-1 in 2015/2016 and 2016/2017 harvest seasons, respectively, with short-time cooking and presenting shoot productivities which allow its use even as animal feed.

BRS 429: sweet cassava with yellow pulp and high technological and sensory qualities

“…The growing and the commercial trade of sweet cassava have been going through a process of expansion and professionalization in the green belt areas of large Brazilian cities (Mendonça et al 2020). Readjustment of the market has been motivated by a continuous and growing demand of consumers for products that combine practicality for consumption, as well as health (Rinaldi et al 2017), sensory (Vieira et al 2018), and nutritional (Carvalho et al 2011) qualities.…”

“…In the Brazilian Distrito Federal and in the states of Paraná and São Paulo, there has been an integration of the sweet cassava production system with cultivation of horticultural crops such as bell pepper, tomato, cauliflower, carrot, and strawberry (Vieira et al 2018, Mendonça et al 2020). This has led to the use of technologies that were not imagined in growing cassava up to a short time ago, such as liming, gypsum application, fertilization, mechanized planting, use of plant beds, irrigation, staggered planting, and use of plastic cover Vieira 2013, Antonini et al 2020).…”

Desempenho agronômico de mandioca de mesa manejada com irrigação e uso de cobertura plástica do solo

“…A mandioca de mesa (Manihot esculenta Crantz) é um dos principais cultivos das áreas rurais, das regiões metropolitanas brasileiras (MENDONÇA et al, 2020). A espécie é cultivada visando o consumo culinário (cozida, frita, chips, mandioca palito, pré-cozida, entre outras) de suas raízes de reserva.…”

“…A espécie é cultivada visando o consumo culinário (cozida, frita, chips, mandioca palito, pré-cozida, entre outras) de suas raízes de reserva. O cultivo é dos preferidos dos horticultores em razão da lucratividade e adaptação à rotação e/ou sucessão de cultivo com outras hortaliças (MENDONÇA et al, 2020).…”
