Sugar beet yield parameters under dry farming

Abstract

Trail with sugar beet was set up during three years. Yield parameters were analyzed on five different origins of sugar beet varieties. Variety had a statistically significant affect on the yield sugar beet. The average yield for all tested varieties was 54.25 t ha-1. The highest average yield was achieved by varieties Chiara, 72.58 t ha-1, and Otis, 64.55 t ha-1 the variety Severina the lowest, 36.76 t ha-1. The variety Severina had the highest average crystal sugar content, 16.65%. Crystalline sugar yield, as the most important indicator of sugar beet yield, statistically significantly depended on the variety. Quality, namely technological root value largely depends of variety. Coarseness of the root was in inverse proportion to the content of sugar.

Ogledi sa šećernom repom izvođeni su tokom tri godine. Analizirani su parametri rodnosti pet sorti šećerne repe različitog porekla. Sorta je imala statistički značajan uticaj na prinosa korena šećerne repe. Prosečan prinos korena za sve testirane sorte iznosio je 54,25 t ha-1. Najviši prinos imale su sorte Chiara, 72,58 tha-1 i Otis, 64,55 t ha- 1, a sorta Severina najniži, 36,76 tha-1. Sorta Severina imala je najveći sadržaj kristalnog šećera, 16,65%. Prinos kristalnog šećera, kao najvažniji pokazatelj rodnosti šećerne repe, statistički je značajno zavisio od sorte. Tehnološka vrednost korena u velikoj meri zavisila je od sorte. Krupnoća korena bila je u obrnutoj proporciji sa sadržajem kristalnog šećera.
