Ključne reči: rezerve semena korovskih biljaka u zemljištu, biodiverzitet, α i β indeksi diverziteta

Sažetak


Efekti intenziviranja savremene poljoprivredne prakse su do sada dobro opisani na nadzemni sastav korova, ali je vrlo malo istražen uticaj na rezerve semena korovskih biljaka u zemljištu. Iz tog razloga, tokom tokom tri godine (2014-2017) uzorkovano je zemljište i procenjena  brojnost semena korova u zemljištu osam različitih sistemima biljne proizvodnje: (i) monokultura kukuruza, ozime pšenice i soje, (ii) dvopoljni plodored (kukuruz - ozima pšenica) sa i bez primene mineralnog đubriva, (iii) tropoljni plodored (kukuruz - ozima pšenica - soja) sa primenom mineralnog đubriva, sa primenom stajnjaka i bez primene đubriva. Procenjena rezerva semena u zemljištu poslužila je za izračunavanje α i β indeksa diverziteta i utvrđivanje raznovrsnosti, bogatstva i ujednačenosti korovske zajednice. Indeksi diverziteta potvrdili su da na diverzitet korovske zajednice utiče strategija rotacije useva kao i izbor đubrenja, da je u monokulturi ozime pšenice najmanja raznovrsnost korovske zajednice, najveći broj dominantnih korovskih vrsta i najmanja uniformnost korovske populacije, dok je u klasičnom tropoljnom plodoredu sa mineralnim đubrenjem najbogatiji biodiverzitet i ujednačenost korovske zajednice.
