Abstract :Ammonium sulfate insert ignore into journalissuearticles values(AMS); and ammonium thiosulfate insert ignore into journalissuearticles values(ATS); are two of the most common sulfur products applied during canola seeding in the Canadian Prairies. A better understanding of how application methods affect the efficiency of these products is warranted. A field trial was conducted on a clay loam soil in Pense, Saskatchewan to evaluate the effect of seed row and side banded sulfur applications on canola yield and quality. Plots received 34 kg ha-1 sulfur either from AMS or ATS applied during seeding either in the seed row insert ignore into journalissuearticles values(SR); or side banded insert ignore into journalissuearticles values(SB);. A treatment without sulfur was included as a control. All plots received the same amounts of all other nutrients. Results showed that average seed yields increased for all sulfur-treated plots, however, only side banded applications insert ignore into journalissuearticles values(AMSinsert ignore into journalissuearticles values(SB);: 4020 kg ha-1 , ATS insert ignore into journalissuearticles values(SB);: 3883 kg ha-1 ); were significantly better than the control insert ignore into journalissuearticles values(3072 kg ha-1 );. Side banded sulfur applications generally produced more protein than seed row applications and were significantly different from the control. AMS insert ignore into journalissuearticles values(SB); had the highest protein content insert ignore into journalissuearticles values(21.07%); while the control had the least insert ignore into journalissuearticles values(18.13%);. Oil content was similar except for AMS insert ignore into journalissuearticles values(SB); insert ignore into journalissuearticles values(46.72%); which was significantly lower than the control insert ignore into journalissuearticles values(48.68%);. However, this oil difference was more than compensated by the increased yield from AMS insert ignore into journalissuearticles values(SB);. Applying AMS and ATS in the seed row can decrease the yield and protein response that might otherwise be seen when these products are side banded. There were no significant differences in the measured parameters between AMS and ATS.
