Effect of application of Sugarcane Filter Muds, Chemical and Biological Fertilizers on Canola Grain Yield and Quality and Some Soil Properties

In order to evaluate effect of sugarcane filter muds and chemical and biological fertilizers application on canola (Brassica napus L.) yield and some of soil properties, a factorial experiment was conducted in 2012 in experimental farm of Ramin (Mollasani) Agriculture and Natural Resources University of Khouzestan. A complete blocks design was used for the experiment with three replication. Different integrated treatments of filter muds and chemical fertilizers including A1: 100 % filter muds, A2: 75 % filter muds and 25 % chemical fertilizers, A3: 50 % filter muds and 50 % chemical fertilizers, A4: 25 % filter muds and 75 % chemical fertilizers and A5: 100 % chemical fertilizers was investigated as an experimental factor. Other experimental factor was biological fertilizers application (with and without biological fertilizers). The biological fertilizers investigated in this study was included nitroxin and barvar2. Application of filter muds had significant effects on canola yield, yield components, grain oil and protein contents. The soil organic matter and salinity also were affected by filter muds significantly. Highest canola grain yield was obtained by integration of filter muds and chemical fertilizers. Increase of filter muds caused to increase of grain oil content and decrease of nitrogen and nitrate content. On the other hand, increase of chemical fertilizers caused to increase of nitrate and nitrogen contents and decrease of oil content. In addition, increase of filter muds result in higher soil organic matter and salinity, simultaneously.
