Effect of Sulfur and Biofertilizers Application on Yield and Yield Components of linseed (Linum ustatissimum L.)

To study the effect of Fertilizer sulfur, Solution phosphor bacteria and Thiobacillus (sulfur oxidizing bacteria) application on yield and yield components of linseed (Linum ustatissimum L), this experiment was conducted based on factorial in a randomized complete block design with three replications. In this study, Sulfur as the main variable in three levels (0, 1000, and 2000 Kg/ha), Phosphate-solubilizing bacteria as sub factor in three levels (0, 100, and 200 gr/ha) and sulfur-oxidizing bacteria (Thiobacillus thiooxidans ) as sub-sub factor in three levels (0, 2, and 4%) were selected. The results showed that Sulfur application has significant positive impact on grain yield and yield components, and usage of 1000 Kg/ha sulfur showed best yield. In addition, twofold and triplet interaction effects showed significantly on yield and all measured traits as, highest yield (2097 kg/ha) was achieved by usage of 1000 Kg/ha sulfur with 100 gr/ha phosphate solubilizing bacteria and 2% Thiobacillus, and lowest seed yield (928. kg.ha) was observed by application of 2000 Kg/ha sulfur with 100 gr.h(varietie: Olay-ozon). )a phosphate solubilizing bacteria and 2% Thiobacillus. Results showed positive effects sulfur and biofertilizers on yield and yield components linseed. However, application of sulfur showed more positive effect on yield linseed in comparison to Phosphate solubilizing bacteria and Thiobacillus.
