Conservation tillage practices including no-tillage and reduced tillage have been widely adopted in the Canadian prairies. However, proper residue management of the previous crops is challenging, which may lead to cold and wet seedbed conditions and improper seed to soil contact during seeding. Despite the availability of high-quality canola (Brassica napus L.) seeds, initial crop establishment in the fields has been observed to be variable and low (approx. 50%). Lack of residue management can further impact canola emergence and seedling survival. Higher seedling emergence is required for improved canola yield and seed quality. This study proposes to test the efficiency of management practices including strip tillage and precision planting in managing crop residues and improving canola emergence, growth and yield. This project will inform the producers of best management practices to be followed to obtain maximum seed yield and quality for canola crop production. Furthermore, project outcomes may help determine if the inclusion of planters, especially for small-seeded crops, is warranted for the agricultural systems in southern Alberta.

免耕、少耕等保护性耕作方法已在全国广泛采用。 加拿大大草原。然而，对前茬作物进行适当的残留管理具有挑战性，这可能会导致 寒冷和潮湿的苗床条件以及播种期间种子与土壤接触不当。尽管有可用的 优质双低油菜籽 (Brassica napus L.) 种子，据观察田间的初始作物定植情况 可变且低（约 50%）。残留物管理的缺乏会进一步影响双低油菜籽的出苗和 幼苗成活。提高双低油菜籽产量和种子质量需要更高的出苗率。 本研究旨在测试条耕和精准种植等管理实践的效率 管理农作物残留物并改善油菜出苗、生长和产量。 该项目将告知生产者应遵循的最佳管理实践，以获得最大的种子 双低油菜籽作物的产量和质量。此外，项目成果可能有助于确定 对于南部地区的农业系统来说，有必要纳入播种机，特别是小种子作物的播种机。 艾伯塔省。
