Organic agriculture: Improvement of production by use of fertilizers, biopreparates and biological measures (MESTD - 31027)

Abstract
One of the biggest problems in organic agriculture is the technology of weed control. Therefore, it is necessary to know the weed flora and their characteristics. During organic production of buckwheat, soybeans, wheat, corn, cabbage, and lettuce in Pančevo, Crepaja, Kisač, Bajmok and Totovo selo, 47 plant species were determined in the weed flora. The ecological analysis of the flora indicates that the studied agroecosystems are: moderately dry to moderately moist (F-2,53), neutral to slightly acidic in chemical reactions (R-3,28), eu-mesotrophic (N-3,74) with a medium humus content (H-2,96), well to moderately aerated (D-3,34), non-saline, with favorable light (L-3,87) and thermal regimes (T-4,02) and with the conditions of the moderately continental climate (K-3,09). In the studied weed flora, three taxa of invasive species were determined in region of Europe, and even seven taxa in the Province of Vojvodina. The results of this study contribute to understanding of weed flora ecological characteristics, and indicate the presence of invasive species in organic production.
