Improving the Content of Oil, Protein and Some Yield Components of Canola in two Calcareous Soil, Consequence the Sulfur and Cattle Manure Application

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 in M2S2 (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 highest on the amount of oil grain and pot number were obtained in T1M2S3 (loam + 4500 kg S with Thiobacillus + 50 ton CM ha-1) treatment.
