Alternative method of sowing canola hybrids using adhesive tape

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.摘要：籽粒细小的油菜（Canola）在种植过程中需精细化管控，以确保植株密度达到理想水平。本研究旨在评估胶带播种的替代方案，探究其对不同油菜杂交品种幼苗出苗率与幼苗活力的影响，并确定构建试验田所需的胶带最佳铺设位置。本试验在戈亚斯联邦大学（Universidade Federal de Goiás）种子实验室开展。试验采用Hyola系列杂交油菜种子（Hyola 50、61、433、571CL及575CL作为供试材料。首先对供试种子开展生理品质表征，随后设置播种处理：无胶带播种组，以及胶带分别朝下、朝侧、朝上铺设的胶带播种组，采用完全随机试验设计，设置5×4因子试验方案。试验测定指标包括沙床条件下的出苗率、出苗速率指数及首次出苗计数。结果表明，胶带的使用并未对油菜杂交品种的幼苗出苗情况产生显著影响；其中Hyola 571CL表现最优，而Hyola 50与61的表现相对较差。
