Uticaj godine na prinos zrna i neke osobine koje su bitne za kvalitetan prinos zrna pšenice zavise od agroekoloških uslova reona gajenja i primenjenih agrotehničkih mera. Kao materijal istraživanja korišćeno je sedam sorti iz više selekcionih kuća, a nalaze se u širokoj proizvodnji. Ogledi su postavljeni na šest lokaliteta: Kikinda, Novi Sad, Pančevo, Sremska Mitrovica, Kruševac i Požarevac, u dve proizvodne godine, po blok sistemu sa četiri ponavljanja. Najveći ukupan prinos zrna pšenice od 8.824 kg ha-1ostvaren je kod sorte NS 40S, zatim 8.817 kg ha-1 kod sorte NS Renesansa, odnosno 8.343 kg ha-1 kod sorte PKB Imperija, dok je najniži prinos zrna pšenice od 7.564 kg ha-1 ostvaren kod sorte PKB Talas. Najveća prosečna masa 1000 zrna pšenice utvrđena je na lokalitetu Sremska Mitrovica (35,12 g), zatim na lokalitetu Požarevac (35,09 g), odnosno na lokalitetu Pančevo (34,98 g), dok je najniža vrednost mase 1000 zrna od 34,25 g ustanovljena na lokalitetu Kruševac. The effect of year on grain yield and certain yield components essential for wheat yield’s quality depends on agro-ecological conditions of the growing area and applied agrotechnical measures. A two-year experiment was conducted at six locations: Kikinda, Novi Sad, Pančevo, Sremska Mitrovica, Kruševac and Požarevac, using the block system, in four replications. In this study, seven winter wheat commercial varieties obtained from several seed companies were evaluated. The highest total wheat grain yield was achieved by the variety NS 40 S (8.824 kg ha-1), followed by NS Renesansa (8.817 kg ha-1), i.e. PKB Imperija (8.343 kg ha-1), while the lowest grain yield of 7.564 kg ha-1 was achieved by the variety PKB Talas. The highest average 1000 grain weight was found at Sremska Mitrovica (35,12 g), followed by Požarevac (35,09 g), i.e. Pančevo (34,98 g), while the lowest 1000 grain weight of 34,25 g was evidenced at the Kruševac experimental site. |
