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

保护性耕作措施包括免耕和少耕，在加拿大大草原已被广泛采用。然而，对前茬作物进行适当的残留物管理具有挑战性，这可能导致苗床条件寒冷和潮湿，以及播种期间种子与土壤接触不当。尽管高品质的油菜（Brassica napus L.）种子，最初的作物建立在田间已观察到bevariable和低（约。50%）。缺乏残留物管理会进一步影响油菜出苗和幼苗存活。提高油菜籽的出苗率是提高油菜籽产量和质量的重要条件。本研究旨在通过对带状耕作和精密播种等管理措施在管理作物残茬、提高油菜籽出苗率、生长和产量方面的效果进行测试，为油菜籽生产提供最佳管理措施，以获得最高的种子产量和质量。此外，项目成果可能有助于确定是否包括种植者，特别是小种子作物，是保证在南阿尔伯塔省的农业系统。

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.
