In order to investigate the effect of application sulfur (S) and cattle manure (CM) on oil and protein percentage and some yield components of canola (Hayola 401) in two calcareous soils, a pot experiment was conducted as factorial based on randomized complete block design with four replications during 2009-2010 cropping season. Treatments included two levels soil texture (loam and clay loam), three CM levels (0, 25 and 50 ton ha-1) and four S levels (0, 1500, 3000 and 4500 kg ha-1) with 2% inoculation Thiobacillus. Results indicated that, soil texture and cattle manure had significant effect on the amount of oil, protein, total dry matter, pod, grain number per pod and 1000-grain weight. But, the effect of soil texture on grain number per pod was not significant. The highest amount of grain protein was obtained in 50 ton CM ha-1 treatment, But, application of different levels of sulfur had no significant effect on the amount of grain protein. Also, the application of S and CM together increased total dry matter and the highest total dry matter was obtained inM2S2 (3000 kg S with Thiobacillus + 50 ton CM ha-1) treatment. The interaction effect between T× CM ×S on the amount of oil grain and pot number had significant effect and the higheston the amount of oil grain and pot number were obtained in T1M2S3 (loam + 4500 kg S with Thiobacillus + 50 ton CM ha-1) treatment .
