Prinos zrna različitih sorti pšenice u organskoj proizvodnji u zavisnosti od rizosferne mikroflore

Abstract

Cilj rada je ispitivanje produktivnosti različitih sorti pšenice u zavisnosti od rizosferne mikroflore u uslovima organske tehnologije gajenja. Najveći prinos zrna u prvoj godini zabeležen je kod sorte krupnika, a u drugoj godini kod sorte obične meke pšenice kod koje je ustanovljeno i veće variranje prinosa u poređenju sa ispitivanim sortama alternativnih vrsta pšenice. Najmanji prinos zrna ustanovljen je kod sorte tvrde pšenice, Dolap, kod koje je zabeležen najmanji broj ispitivanih grupa mikroorganizama. Testiranjem značajnosti regresionog modela ustanovljeno je postojanje statistički značajne promene prinosa pšenice u zavisnosti od brojnosti Azotobakter-a (r=0,76), ali ne i od ukupnog broja mikroorganizama (r=0,24).

The aim of this paper is testing the productivity of various wheat varieties depending on the rhizosphere microflora in terms of organic cultivation technology. The highest yield in the first year was recorded in cv spelt, and in the second year at ordinary soft wheat varieties for which it was established and greater variation in yield compared to alternative types of wheat varieties. The lowest yield was detected among varieties of durum wheat, Dolap, in which it recorded the lowest number of investigated microbial groups. By testing the significance of regression model was found a statistically significant change in the yield of wheat depending on the number of Azotobacter (r = 0.76), but not the total number of microorganisms (r=0,24).
