Abstract: The aim of the study is to assess the degree of influence of “fertilization” and “soil tillage” factors as well as the impact of soil and climatic conditions on wheat grain yield, obtained on Gleyic-Chromic Luvisols in the region of Gorni Lozen and Haplic Vertisols in the region of Bozhurishte. The study was conducted on the basis of data from field experiments with wheat, grown in crop rotation with maize. The influence of fertilization on the wheat grain yield is statistically proven for the two experimental stations Gorni Lozen and Bozhurishte at a significant level of p<0,1%. 78,55% of the total variation in the yields of Gorni Lozen and 94.03% for Bozhurishte are due to the influence of this factor. The soil tillage is a factor that has a significant impact on the yield only in Bozhurishte and the yields, obtained by ploughing at 12-15 cm were found to be higher than those obtained at a 10-12 cm by disking. The soil-climatic conditions for the year of experiment, as well as the input of
foliar fertilizer, have no statistically proven impact on yield.
