Sažetak

Poljski ogledi su izvedeni tokom 2017. godine na lokalitetu Concord na severoistoku savezne države Nebraska, SAD. Cilj ogleda je bio da se oceni kako različita vremena uklanjanja korova i primena PRE-EM herbicida utiču na rast i razvoj useva soje. Ogled je rađen po principu split- plot rasporeda sa 14 tretmana (2 različita režima primene PRE-EM herbicida i 7 različitih vremena uklanjanja korova) u četiri ponavljanja. Dva režima primene PRE-EM herbicida: režim bez primene PRE-EM herbicida i režim sa primenom PRE-EM herbicida na bazi mešavine sulfentrazona i imazetapira (140 i 28 g a.s. ha-1). Sedam vremena uklanjanja korova je bilo: V1, V3, V6, R2 i R5 faza razvoja soje, kao i nezakorovljena i zakorovljena kontrola. Vegetativni parametri soje (lisna površina i suva masa) su ocenjivani tokom R6 faze razvoja useva. Odloženo vreme uklanjanja korova je imalo značajnog uticaja na rast soje, time što su lisna površina i suva masa bili značajno redukovani. Bez primene PRE-EM herbicida redukcija lisne površine i suve mase soje za 5% se poklopilo sa odlaganjem uklanjanja korova od 100 GDD nakon nicanja soje (što korespondira sa V1 fazom razvoja soje, odnosno 10 dana nakon nicanja [DNN] useva). Međutim, primena PRE-EM herbicida je dodatno odložila ovo smanjenje, što korespondira sa 382 GDD nakon nicanja soje (što se poklapa sa V5 fazom razvoja soje, odnosno sa 34 DNN-a soje). Na osnovu dobijenih rezultata može se konstatovati da primena PRE-EM herbicida može da zaštiti soju od smanjenja rasta i odloži POST-EM primenu herbicida i do tri nedelje nakon nicanja useva.
