Canola ((i>Brassica napus L.) yields may be influenced by previous crop, tillage, and N fertilization. The objective of this study, conducted in 2002-2003 and 2003-2004, was to evaluate the influence of two tillage systems (no-till and para-till plus harrow), two N rates (0 and 80 lb/A) on canola following fallow and soybean [Glycine max (L.) Merr.]. In 2003, greater canola seed yields were obtained with the application of 80 lb N/A compared to treatment without N fertilization (31.8 vs. 19.7 Bu/A). Canola yields were not influenced by previous crop and tillage systems. In 2004, a tillage x N rate interaction was observed for seed yields. Greater canola yields were noted with N fertilization than without fertilizer application on treatment with para-till plus harrow (30.1 vs. 9.9 Bu/A), while seed yields were not influenced by N application under no-till system. Additionally, higher canola seed yields were obtained after soybean than fallow (15.0 vs. 9.3 Bu/A) in 2004. The same year, dry matter yields were greater under para-till plus harrow than no-till system (3.40 vs. 1.84 T/A). Nitrogen application increased dry matter yields from 1.9 T/A to 3.35 T/A in 2004. The results of this study indicate that canola yields can be increased with N fertilization under para-till plus harrow management. Also, growing canola after soybean would help to maximize yields due to N utilization from the previous crop.
