The effect of bacterial inoculation and nitrogen doses on yield and yield components on common beans (Phaseolus vulgaris L.).

This research conducted in 2018 spring and early summer in Diyarbakir conditions to determine the effect of nitrogen and bacteria applications (0, 4, 9, 12 kg/da, bacteria inoculation (Rhizobium phaseoli) and bacteria + 4 kg/da ) on yield and yield components.on some common bean varieties (Göynük 98 and Cihan). Experiment set out on randomized complete block deisgn by split plot with three replications. The plots designed 4 m length and in 70 cm row spacing. The seeds sowned on April 13. In the study, the days to 50% flowering, days to maturing, plant height, number of branches per plant, number of pods per plant, grain yield and 100 seed weight were examined. The effect of the fertilizer application on plant height, the first pod height, number of pods per plant, pod weight per plant were significant. The highest plant height was obtained from bacteria and bacteria + 4 kg / da nitrogen applications. The highest number of pods per plant was found to be 4 kg of nitrogen per decare. Grain yield and biological yield were higher in the control group than nitrogen and bacteria applications. Climatic condition is an important limiting factor in common bean cultivation in Diyarbakir. Low yield values are the result of competition between plant and climatic conditions.
