This research was conducted at the Research and Application Farm, Faculty of Agriculture, University of Ankara during the growing periods of 1996-1998. Winter Hungarian vetch treated with different inoculation methods (no inoculation, seed inoculation and soil inoculation) and nitrogen doses (0, 2, 4 kg N/da) was harvested in two periods (for hay and seed). Yield and some yield components of Bezostaja 1 bread wheat variety, which was sown in the same plots, were studied. According to the results of the study, harvest times (for hay and seed) caused significant differences in plant height, spike length and grain yield of wheat. The variation in plant height, spike length, number of spikelets per spike, number of seeds per spike, yield per spike, harvest index and grain yield with respect to inoculation methods was significant. All features examined were not significant with respect to nitrogen doses. Grain yields of wheat sown after Hungarian vetch harvested for seed and hay were 348.63 to 403.17 kg/da, and 368.31 to 416.39 kg/da, respectively. Grain yield of wheat in the same year and conditions in fallow-wheat rotation was 330 kg/da. In Ankara conditions, vetch - wheat rotation may be suggested instead of the fallow-wheat rotation system with respect to higher wheat yield.
