The Influence of Plant Density and Variety on Sugar Beet Root Yield and Quality

Abstract

In this work the influence of crop density and sugar beet varieties of different types (Alfonsa- E type, Marianka KWS- Z type and Serenade KWS EPD - N type) on the yield and quality of sugar beet roots was achieved. Field micro experiments were carried out in agroecological conditions of Central Banat using split plot method in five replications, on a calcareous chernozem soil type. The results showed statistically significant differences in root yield between the genotypes in both years. On the sugar content in root statistically significant effect demonstrated the tested varieties only in 2014. The highest root yield was obtained in crop density of 120,000 plants ha-1 (75.55 t ha-1). Alfonsa variety is determined by the highest root yield (76.35 t ha-1), and the lowest sugar content in root (13.64%).

U radu je proučavan uticaj gustine useva i sorti šećerne repe različitog tipa (Alfonsa- E tip, Marianka KWS- Z tip i Serenada KWS EPD – N tip) na prinos i kvalitet korena šećerne repe. Poljski mikroogledi su izvedeni u agroekološkim uslovima srednjeg Banata po metodu razdeljenih parcela (split plot) u pet ponavljanja, na zemljištu tipa karbonatni černozem. Dobijeni rezultati su pokazali statistički vrlo značajne razlike u prinosu korena između ispitivanih genotipova u obe godine istraživanja. Na sadržaj šećera u korenu statistički vrlo značajan uticaj ispoljile su ispitivane sorte samo u 2014. godini. Najveći prinos korena dobijen je u gustini useva od 120.000 biljaka/ha (75,55 t ha-1). U prinosne sorte Alfonsa utvrđen je najveći prinos korena (76,35 t ha-1), a najmanji sadržaj šećera u korenu (13,64%).
