AB  - Weed seed banks may reflect the status of weed population in the present and the past, and could be regarded as an indicator of the impact of soil and crop management. Crop rotation and fertlization system are among the many agronomic variables that interact with weed management to affect the size and composition of the weed seedbank. Knowledge of the effects of agricultural practices on weed seedbank dynamics is essential for predicting future problems in weed management. The aim of this study was to determine how the impact of the different growing system: monocultures of maize, 2-year crop rotation (maize, wheat) and 3-year crop rotation (wheat, maize, soyabeans) and the application of different fertilization systems: 2-year crop rotation (unfertilazation and fertilization with NPK) and 3-year crop rotation (unfertilization, fertilization with manure and fertilization with NPK) affects the composition of the weed seed bank. For these surveys the plots of stationary experiment "Plodoredi", Institute of Field and Vegetable Crops, Novi Sad, Serbia (N 45° 19', E 19° 50') were used (plots were established in 1969/70). In each fertlized crop rotation was used 100 kg ha-1 mineral N (50 kg in autumn and 50 kg in spring). In order to determine the weed seed bank, soil samples were taken for three years (2014-2017) in the autumn (after harvest) and spring (before sowing) and from three depths: 0-15 cm, 15-30 cm and 30-40 cm. The seedling emergence method was used to assess the emergence of the 432 soil samples. The method was carried out under controlled conditions of largest number of seedling was observed between 3 and 6 weeks, in samples taken from the ploughlayer (0-15 cm). It was concluded that the smallest number of species present (8) in maize monoculture samples was recorded (at the depth 0-15 cm there were 6 species, at 15-30 cm 5 species and at 30-40 cm 4 species). While the change in maize with wheat increased the number of weed species to 12 (0-15 cm: 11 species; 15-30 cm: 9 species; 30-40 cm: 5 species) and 17 respectively in the rotation of maize, wheat and soyabeans (0-15 cm: 10 species; 15-30 cm: 9 species; 30-40 cm: 7 species). There are 14 weed species (0-15 cm: 9 species; 15- 30 cm: 9 species; 30-40 cm: 8 species) on the plots of the 2-year crop rotation where no fertilizer is applied, and in the fertilizer variant with NPK nutrients 12. In the samples with three plots of the 3-year crop rotation and different varieties of fertilization, a similar number of weed species were observed, but they differ in the floristic manner. Thus, in the non-fertilizer samples (0-15 cm: 12 species; 15-30 cm: 10 species; 30-40 cm: 7 species) the most important species were Ajuga chamaepytus L., Anagalis arvensis L., Sorghum halepense L., Stachys annua L. In the plots where a manure is applied every three years in the amount of 40 t ha-1 Ambrosia artemiisifolia L., Chenopodium hybridum L., Chenopodium album L. Veronica hederifoila L. are dominated. At the depth 0-15 cm there were 8 species, at 15-30 cm 12 species and at 30-40 cm 7 species. Only during the using samples at this locality, a large populations of invasive species Helianthus tuberosus L. is observed. In the area of Serbia in occational years when climatic conditions permit this species is propagated generatively. Normally it is maintained in the form of tubers in the soil weed seedbank. In the samples where only NPK fertilizer was applied, the state of weed species was similar (17 species) but Datura stramonium L., Polygonum aviculare L., Portulaca oleraceae L. occured, too.

AB  - Plodored, obrada zemljišta i nega useva koja uključuje i mere suzbijanja korova su u direktnoj korelaciji sa sadržajem rezervi semena korovskih biljaka u zemljištu. Prognoza pojave korova na obradivim površinama zasniva se na poznavanju rezervi semena korovskih biljaka. Ova pojava je posebno izražena kod korovskih vrsta koje imaju veliku produkciju ili izuzetnu dugovečnost semena. Poznavanje rezervi semena i dinamike pojave korova je osnova u planiranju i sprovođenju mera za efikasno suzbijanje korova. Metod naklijavanja semena predstavlja pouzdan način za procenu rezervi semena korovskih biljaka jer omogućava utvrđivanje vrsta čija su semena prošla period mirovanja i time su spremna da daju novu biljku u povoljnim agroekološkim uslovima. Cilj ovog istraživanja je bio da se utvrdi procena rezervi semena korovskih biljaka u zemljištu u zavisnosti od plodoreda i sistema đubrenja. U cilju dobijanja procene rezervi semena korovskih biljaka uzorkovanje zemljišta obavljeno je na stacioniranom dugogodišnjem ogledu „Plodoredi“, Instituta za ratarstvo i povrtarstvo, Novi Sad u trogodišnjem periodu i to: u proleće (pre setve useva) i u jesen (nakon žetve) sa tri različite dubine: 0–15 cm, 15–30 cm i 30–40 cm. Metod naklijavanja semena obavljen je u kontrolisanim uslovima staklenika u trajanju od 12 nedelja. Tokom naklijavanja semena izvedena je i determinacija ponika. Najveći broj ponika utvrđen je između 3 i 6 nedelje ogleda i to u uzorcima uzetih iz oraničnog sloja. Dobijeni rezultati istraživanja su pokazali da je u uzorcima monokulture kukuruza konstantovan najmanji broj prisutnih vrsta (8), dok se smenom kukuruza sa pšenicom brojnost korovskih vrsta povećava na 12, odnosno 17 korovskih vrsta u rotaciji tri useva (pšenica, kukuruz, soja). Na dvopoljnon plodoredu (kukuruz–pšenica) bez primene mineralnih đubriva determinisano je 14 korovskih vrsta, odnosno plodoredu (kukuruz–pšenica) uz primenu NPK mineralnih đubriva, ukupno 12 vrsta. U okviru tropoljnog plodoreda sa različitim sisitemom đubrenja utvrđen je sličan broj prisutnih korova, ali je konstatovana razlika u florističkom sastavu vrsta. U uzorcima sa varijanti ogleda gde se primenjuje stajnjak svake treće godine u količini od 40 t ha-1 dominiraju vrste: Amaranthus retroflexus L., Ambrosia artemisiifolia L. Chenopodium hybridum L., C. album L. i Veronica hederifoila L. U uzorcima zemljišta sa neđubrenih varijanti najveće učešće imale su vrste Ajuga chamaepytus L., Anagalis arvensis L., Stachys annua L., Sorghum halepense L, dok na varijantama ogleda sa primenom NPK mineralnih đubriva konstantovani su ponici sledećih korova: Datura stramonium L., Polygonum aviculare L. i Portulaca oleraceae L.

AB  - Knowledge of weed soil seed bank is of great importance for forecasting weediness for next years. Crop rotation and tillage are two primary practices that have an impact on soil seed bank. In our study, soil samples were taken in order to evaluate the size and species composition of the weed seed bank in the soil on plots under different growing systems: monoculture of corn of about 40 years, crop rotation of corn, wheat and soybeans with different variations of fertilization. Samples were collected during October, using probe (diameter 5 cm) in a layer of 15 cm. Four soil samples collected from 10 sampling points were taken from each of 7 plots. Seeds were extracted from the soil by washing and were determined and counted. Next year (during August) weediness (abundance and species composition) evaluated in the same plots. The weed seed bank was dominated by Chenopodium album, Amaranthus retroflexus, Datura stramonium, Sorghum halepense in all treatments. In the plots which were under wheat in the previous year, beside the listed species, seeds of species characteristic for grain crops were also present as dominant. The higher number of seeds was observed in treatments where manure was applied. In the unfertilized treatments the seed bank was higher and represented by a higher number of weed species than in other plots. Composition of weed species emerged in the next year were in accordance with results of seed bank analysis and the fact that the investigated plots were seeded to maize. In fact, the dominant species were those typical of row crops.
