Uticaj sorte i roka vađenja na prinos i kvalitet šećerne repe

During two-year period (20013 and 2014), the influence of different harvest dates (25.8-1.9. and 28.10-10.11) on sugar beet yield and quality of selected genotypes was conducted. Research was carried out by field micro experiments in agroecological conditions of Midle Banat (Zlatica, Zrenjanin) on chernozem soil type. Experiments were conducted by total random block system method in five replications. The obtained results show that higher root yield was given by the later-second harvest date, and sugar content by the earlier-first harvest date. Statistical differences were at very high level. The highest root yield was given by cv. Alfonsa and the sugar content by cv. Jasmina EPD.U dvogodišnjem periodu (2013-2014) ispitivan je uticaj različitih rokova vadenja (25.8-1.9. i 28.10-10.11) na prinos i kvalitet odabranih genotipova šećerne repe. Istraživanja su obavljena putem poljskih mikroogleda u agroekološkim uslovima srednjeg Banata (lokaliet “Zlatica’’) na zemljištu karbonatni cernozem. Ogledi su postavljeni po metodi potpuno slučajnog blok sistema u pet ponavljanja. Dobijeni rezultati istraživanja pokazuju da je veći prinos korena šećerne repe dobijen u drugom roku vadenja, a veći sadržaj šećera u prvom roku vadenja. Ove razlike su statisticki vrlo značajne. Najveći prinos koren dala je prinosna sorta Alfonsa, a najveći sadržaj šećera zabeležen je u genotipa Jasmina EPD
