Conservation tillage practices including no-tillage and reduced tillage have been widely adopted in theCanadian prairies. However, proper residue management of the previous crops is challenging, which may leadto cold and wet seedbed conditions and improper seed to soil contact during seeding. Despite the availability ofhigh-quality canola (Brassica napus L.) seeds, initial crop establishment in the fields has been observed to bevariable and low (approx. 50%). Lack of residue management can further impact canola emergence andseedling 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 plantingin 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 seedyield and quality for canola crop production. Furthermore, project outcomes may help determine if theinclusion of planters, especially for small-seeded crops, is warranted for the agricultural systems in southernAlberta.

thecanadian大草原已广泛采用，包括无耕作和减少耕作在内的保护耕作实践。但是，对先前农作物的适当残留物管理具有挑战性，这可能会导致寒冷和潮湿的苗床条件，并在播种过程中与种子接触不当。尽管高品质的低芥酸菜籽（Brassica napus L.）种子的可用性，但已经观察到该田间的初始农作物可容纳且较低（约50％）。缺乏残留管理可以进一步影响低芥酸菜籽和种植生存。提高了低芥酸菜籽和种子质量需要更高的幼苗出现。这项研究建议测试管理实践的效率，包括耕作和精确种植，以管理农作物残留物以及改善低芥酸菜子的出现，增长和产量。该项目将告知最佳管理者的生产国遵循的做法以获得菜籽作物生产的最大含量和质量。此外，项目成果可能有助于确定种植者的包含，尤其是对于小种子作物，南部的农业系统有必要。
