Title:
 Evaluation of regional variability and spatial correlations of yields for main crops and rates of fertilization

Language: English

Summary:
This work presents evaluation of spatial correlations between yields of main crops and rates of fertilization in the sixteen voivodships of Poland. The analyses were conducted using data from the years 2000 and 2007. Spatial relationshps were evaluated on the base of coefficients of autocorrelation between quantities of crop yields. Voivodships significantly different from their neighbours were pointed out on the basis of the values of local spatial autocorrelation coefficients. Strong positive autocorrelation between crop yields of winter triticale and potatoes was proved, but the lack of such autocorrelation for yields of rapeseed and spring wheat was observed.
