Abstract
The survey results for private farms cultivating winter wheat within the years 1992–2003 were analyzed statistically. Each of the fields described in the survey was characterized by different environmental conditions (soil quality, pH of soil, forecrop) and different level of technological factors (fertilization, manure, chemical protection, sowing amount, sowing term and material). This made possible to consider each of the fields as a separated cultivation technology. Using the method of multidimensional factor analysis an attempt was undertaken to separate groups including similar technological methods. Then, the groups were characterized.
