Effect of strip tillage and precision planting on Canola emergence, seed yield and quality

包括免耕和少耕在内的保护性耕作措施在加拿大大草原上得到了广泛采用。然而，对前茬作物进行适当的残留物管理是具有挑战性的，这可能会导致苗床条件寒冷潮湿，播种过程中种子与土壤接触不当。尽管有高品质的油菜(Brassica napus L.)种子，已经观察到田间的初始作物建立是可变的和低的(约。50%)。缺乏残留物管理会进一步影响油菜出苗和幼苗存活。油菜产量和种子质量的提高需要更高的出苗率。这项研究建议测试包括条带耕作和精准种植在内的管理措施在管理作物残留物和改善油菜出苗、生长和产量方面的效率。该项目将告知生产者应遵循的最佳管理实践，以获得油菜作物生产的最大种子产量和质量。此外，项目成果可能有助于确定是否有必要为南艾伯塔省的农业系统纳入播种机，特别是小种子作物的播种机。

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.
