Influence of the insecticides on sugar beet germination in field conditions

Abstract

Aim of this research was to determine influence of the insecticides on sugar beet germination in field conditions. Further, connection between field germination and yield was also analyzed. Trials were conducted during two years, 2010 and 2011, with the most common insecticides used for this purpose. Some of them were used as seed treatment and some were incorporated in soil during sowing. As a seed was used hybrid variety Lara from Institute of field and vegetable crops, Novi Sad. Statistical analysis showed that treatments with insecticides imidacloprid, thiamethoxam and furathiocarb had the highest rates of field germination. Also, high positive correlation was determined between field germination and sugar beet yield.

Osnovni cilj rada je da se odredi uticaj insekticida na poljsku klijavost šećerne repe. Analizirana je i međuzavisnost poljske klijavosti i prinosa korena šećene repe. Ogled je izveden tokom dve godine, sa kod nas najčešće primenjivanim insekticidima u peleti semena šećerne repe, kao i unošenjem insekticida u zemljište. Kao seme poslužila je hibridna sorta Lara, nastala u Institutu za ratarstvo i povrtarstvo. Statistički visoko značajnu poljsku klijavost ostvarilo je seme tretirano insekticidima imidakloprid, tiametoksam i furatiokarb. Visoka pozitivna korelacija ustanovljena je između poljske klijavosti i prinosa korena šećerne repe.
