ORIGINAL PAPER
Analysis of relationships and strenght connection between nitrogen ferttilizer use and crops type in Poland
Journal of Research and Applications in Agricultural Engineering 2011;56(2):87-89
KEYWORDS
ABSTRACT
The aim of study was to determine the strength depending on use of nitrogen fertilizers and crop type. Strength of linear relation between traits were determined by Pearson's linear correlation coefficient. Conformity with the normal distribution was verified using the Shapiro-Wilk test. The impact of the variables was tested by regression analysis. Analysis was performed using the statistical package R-Project.
