Özet

This study was conducted to investigate the effects of root inoculations with Bacillus cereus (N-2-fixing), Brevibacillus reuszeri (P-solubilizing), and Rhizobium rubi (both N-2-fixing and P-solubilizing) on plant growth, nutrient uptake, and yield of broccoli in comparison with manure (control) and mineral fertilizer application under field conditions in 2009 and 2010. Bacterial inoculations with manure compared with control significantly increased yield, plant weight, head diameter, chlorophyll content, nitrogen (N), potassium (K), calcium (Ca), sulfur (S), phosphorus (P), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) content of broccoli. The lowest yield per plant, plant weight, steam diameter, and chlorophyll content were recorded in the control, but the manure with Bacillus cereus (BC), Rhizobium rubi (RR), and Brevibacillus reuszeri (BR) inoculations increased yield 17.0%, 20.2%, and 24.3% and chlorophyll content by 14.7%, 14.0%, and 13.7% over control, respectively. Bacterial inoculations with manure significantly increased uptake of macronutrients and micronutrients by broccoli. In conclusion, seedling inoculation with BR and especially RR may partially substitute costly synthetic fertilizers in broccoli.
