Özet

The experiments were established during the 2017 and 2018 at the experimental area of the Faculty of Agriculture, Eskisehir Osmangazi University, Eskisehir, Turkey. The experiment was designed as factorial arrangement in the complete randomized block design with four replications. 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). The effects of year, rhizobia and nitrogen fertilization were significantly for all of the investigated characters. All of the investigated characters were higher in the 2017 than the 2018 except for the canopy temperature. Rhizobia application and 50 kg ha-1 DMPP were positively affected all investigated characters. The most likely reason for the increase in crop yield was that N loss through soil NH3 volatilization was not increased by DMPP application. The benefits for the nitrification inhibitors are increases in yields and reduced fertilizer use.
