Determination of Yield and Some Quality Traits of Varied Types of Sugarbeet (Beta vulgaris var. saccharifera L) Cultivars Harvested at Different Times

The present study was carried out at Isparta ecological conditions during 2012 and 2013 crop seasons to determine the effects of different harvest times (140, 155, 170, 185 and 200 days after emergence) at different types of sugarbeet cultivars (Begonia, Aranka and Esperanza (N types), Sandrina and Esperia (NZ types), Felicita and Agnessa (Z types) on yield and some quality parameters.The highest sugarbeet yield and biyological yield per decare were obtained from Aranka cultivar at early harvest times and from Esperia cultivar at lates harvest times. The lowest amount of α-amino nitrogen were determined from Aranka (5.68 mmol/100g) at early harvest and from Esperia (2.05 mmol/100g) and Esperanza (2.11 mmol/100g) cultivars at late harvest time. The highest polar sugar content were determined from Felicita and Agnessa cultivars (Z types) at early and late harvests. The highest polar sugar yield per decare were obtained from Aranka cultivar (1490 kg/da) at early harvest and from Esperia cultivar (1867 kg/da) and Sandrina (1860 kg/da) cultivars at late harvest. It was concluded that Aranka and Begonia cultivars should be completed 200 days while other cultivars at least 150 days of vegetation period in terms of high root yield and technological quality in Isparta conditions
