Nitrogen Inhibators and Rhizobia Can Improve Yield and Yield Components in Bean

The aim of this study is investigation of the effects of rhizobia and different nitrogen fertilizer types and doses on yield and some yield components for bean. The field experiment was conducted during the 2017 and 2018 at the experimental area of the Faculty of Agriculture, Eskisehir Osmangazi University, Eskisehir, Turkey. The experiments were laid out as a randomized complete block design in a factorial arrangement and replicated four times per treatment. In this study, rhizobia and non-rhizobia were investigated at different nitrogen fertilizer types and doses (control, 25 kg ha-1 AS, 25 kg ha-1 DMPP, 50 kg ha-1 AS and 50 kg ha-1 DMPP). Bean varieties Goynuk-98 was used research material. The effects of year were significantly for all of the investigated characters but differences between the rhizobia and nitrogen fertilization were significant were all of the investigated characters except for plant emergence number. All of the investigated characters were higher in first year than second year due to climatic conditions. Rhizobia inoculation was increased yield and yield components. 50 kg ha-1 DMPP nitrogen fertilization types and doses were provided highest values for investigated characters and grain yield. Inoculation with rhizobia and 50 kg ha-1 DMPP application can be recommended for beans in Eskişehir conditions.
