This research was carried out in Bursa Uludag University Faculty of Agriculture Application and Research Center in 2017-2018 growing season. In the experiment, Pehlivan variety, which was cultivated extensively in our region and country, was used as plant material. The experiment was established in randomized split-plot design with three replications and nitrogen fertilizer doses were taken as main plots and vermicompost doses were taken as sub-plots. In the study, pure nitrogen dose of 16 kg/da used in agricultural activities in the region was taken as 100% and 50%, 25% and 0% doses of this value were used to determine the effect of reduced nitrogen doses on the plant. The applied vermicompost doses were given to the parcels with the calculation of 0, 50, 100, 150, 200 kg/da. In order to determine the effect of different doses of chemical nitrogen and vermicompost on plants, plant height, spike length, number of spikes, number of grain per spikes, grain weight per spike, 1000 grain weight and grain yield per decare were investigated. The effect of vermicompost doses on the number of grain per spike and spike grain weight traits was statistically significant at 0.05%. It was determined that the vermicompost doses increased the number of grains per spike and the highest value with 29.23g was obtained from the dose of 200 kg / da. Similar results were determined for grain weight per spike, and with increasing application of vermicompost doses, there was an increase in grain weight. When nitrogen applications are evaluated as average of grain yield, it is seen that 100% N application has a clear advantage over other applications. In contrast, vermicompost applications were determined to have no effect on yield.
