In this research were examined three different grape varieties Tempranillo, Sangiovese, Petit Verdot a period of 2010-2012 at the locality Lepovo, near Negotino an altitude of 250 m. The main parameters in these research are yield (kg/ha) and chemical characteristics of the must, sugar (g/L) and total acids (g/L) from this three grape varieties. The climatic factors, the vegetative sum of precipitation and the vegetative temperature sum measured at the meteorological station on Winery Bovin, at the locality Lepovo. We made a comparison between the correlation coefficient among the climatic factors and yields for each variety individually and correlation coefficient between climatic factors and chemical characteristics of each grape variety. The obtained results from this work were statistically processed using the SPSS statistical software package 19, from where it can be measure the frequency, the percentage share of data, measures of central tendency (median, standard deviation, dispersion, arithmetic mean), such as graphic representation of data (a histogram). The analysis indicates that there is a high correlation value between yield and climatic factors, chemical characteristics and climatic factors. Although the correlation between yield, sugar and total acids in the must with the vegetative sum of precipitation is a negative value, still shows a high correlation coefficient.
