The cluster analysis reveals linkages between crops classes as well as between different crops, which can be partly assigned to crops rotation. Time series analysis reveals dramatically reducing of production of some crops, such as flax, hemp, and sugar beet, and increasing of production, such at sunflower, and increasing of productivity, such at potatoes and field vegetables. date: 2007-10-01 date_type: published publication: Bulletin of University of Agricultural Sciences and Veterinary Medicine - Agriculture volume: 63-64 publisher: AcademicPres pagerange: 194-202 refereed: TRUE referencetext: ***, Agriculture and Sylviculture (Chapter 14th) [online document].
