--- abstract: 'Staring from descriptive data on crop production and cultivated area at national level during on fifteen years, the aim of this study is to reveal the trends on crops cultivation. 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.' altloc: - http://lori.academicdirect.org/articles/work_list.php?user=lori&id=155 chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - lori@academicdirect.org - sbolboaca@umfcluj.ro - carmen@j.academicdirect.ro creators_name: - family: JÄNTSCHI given: Lorentz honourific: Dr. lineage: '' - family: BOLBOACA given: Sorana D. honourific: Dr. lineage: '' - family: STOENOIU given: 'Carmen E,' honourific: '' lineage: '' date: 2007-10-01 date_type: published datestamp: 2007-10-12 16:39:07 department: ~ dir: disk0/00/00/57/43 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: MARGHITAS given: Liviu Al. honourific: Prof. Dr. lineage: '' - family: PAMFIL given: Doru C. honourific: Prof. Dr. lineage: '' - family: SESTRAS given: Radu E. honourific: Prof. Dr. lineage: '' eprint_status: archive eprintid: 5743 fileinfo: /style/images/fileicons/application_pdf.png;/5743/1/work_list.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: Resources Management; Crops Production; National Trends; Cluster Analysis lastmod: 2011-03-11 08:56:58 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: 194-202 pubdom: TRUE publication: 'Bulletin of University of Agricultural Sciences and Veterinary Medicine - Agriculture' publisher: AcademicPres refereed: TRUE referencetext: "***, Agriculture and Sylviculture (Chapter 14th) [online document].
