Effects of Bacterial Inoculation and Molybdenum Application on Nutrient Element Content of Beans

This study was carried out to determine the effect of different doses of molybdenum with bacterial inoculation on macro and micro- elements content ofbean grains. In this study, Akman 98 dry bean variety was used as plant material, Molybdenum dosages were Mo0 = Molybdenum free, Mo1 = 0.05 mg/kg,Mo2 = 0.10 mg/kg and Rhizobium tropici (CIAT899), bacterium of Phaseolusplant, was used as inoculation material. The study was planned according tothe randomized complete blocks in factorial design with three replicates. Following the performed field trial, nutrient elements (N, P, K, Ca, Mg, Fe, Cu,Mn, and Zn) of bean grains were determined. According to the results obtained from the study, the effect of molybdenum application and inoculation onnutrient elements of bean grains was different and statistically significant. Thiseffect on nutrients showed that the nutrients in the bean grains generally increased due to the increase in molybdenum doses. Mineral content of beangrains were determined as nitrogen (N) 3.59-4.39, protein content 22.44-27.44,phosphorus (P) 0.36-0.46 potassium (K) 1.83-2.33 magnesium (Mg) 0.17-0.20calcium (Ca) (%), as mg/kg (Fe) 37.59-65.25 copper (Cu) 5.27-7.69 manganese (Mn) 14.98-16.96 zinc (Zn) 14.77-27.28. The nutrient contents of inoculated bean grains were found to be higher than the non-inoculated ones. Nutrient contents were different depending on the inoculation and dose applications,and this difference was found to be statistically significant.
