ABSTRACT

Canola, which has tiny oil-producing seeds, requires care during planting, so that there is an ideal number of plants. The aim of this study is to evaluate alternative method of sowing using adhesive tape and the influence it has on the emergence and vigor of the seedlings of different canola hybrids and define the best positioning of the adhesive tape for the formation of the experimental field. The study was carried out at the Seed Laboratory at the Universidade Federal de Goiás. The tests were conducted with hybrid canola seeds (Hyola: 50, 61, 433, 571CL and 575CL). The seed characterization was performed in terms of physiological quality. They were then sown: without adhesive tape; seeds arranged on adhesive tape with the tape facing down, sideways and up, with a completely randomized experimental design, in a 5x4 factorial scheme. The evaluations were performed: emergence, speed of emergence index and first seedling emergence count in sand. The use of the adhesive tape did not interfere in the emergence of canola hybrids seedlings, with the Hyola 571CL characterized as having the best performance while the Hyola 50 and 61 had inferior performances.
