摘要

This project aims to compare the low disturbance hoe (H) and double disc (D) opener in various field conditions.Comparing residues of pea (Pr), wheat (Wr), and canola (Cr), in the Residue site, pea as a previous residue allowed canola to be seeded the most uniformly, emerge the quickest, and have the highest plant stand. Wheat produced the most amount of hairpinned residue in both years, followed by canola and pea.The disc opener seeded deeper than the hoe opener and more uniformly in 2001, but not 2002. The seed placement outside the wheel track was slightly deeper than inside the wheel track for both types of openers, however, they were not statistically significantly different. The disc opener was also shown to have a lower seed row roughness, as well as a lower weed percentage. However, the low negative correlation determined between seed row roughness and weed cover percentage indicated no strong linear association between the two variables.The Oat-stubble study showed that the stubble height was significant factor when seeding into adequate soil moisture.
