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 of bean grains. In this study, Akman 98 bean variety was used as plant material, Molybdenum dosages were Mo0 = Molybdenum free, Mo1 = 0.05 ppm, Mo2 = 0.10 ppm and Rhizobium tropici (CIAT899), bacterium of Phaseolus plant, was used as inoculation material.  The study was planned according to the randomized complete block factorial design with three replicates. Following the performed field trial, nutrient elements (N, P, K, Ca, Mg, Fe, Cu, Mn, Zn) of bean grains were determined.  According to the results obtained from the study, the effect of molybdenum application and inoculation on nutrient elements of bean grains was different and statistically significant. This effect on nutrients showed that the nutrients in the bean grains generally increased due to the increase in molybdenum doses . Mineral content of bean grains were determined as  nitrogen (N) 3,59-4,39 phosphorus (P) 0,36-0,46 potassium (K) 1,83-2,33 magnesium (Mg) 0,17-0,20 calcium (Ca) (in % form), 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.
