“…Figures were displayed using Excel 98 software (MSOffice, Microsoft) and the significance level of the best-fitted curves was determined by SPSS (version 14.0, SPSS Inc., IL, USA). Confirming previous reports (Barocka 1978;van Bockstaele 1990;Märländer et al 2003), the productive traits were affected by year, site, cultivar and their interactions (Table 2). Analogous results were also reported for other tap-rooted species (Iwata et al 1998).…”

In a two-year (2002)(2003) field study, six sugar beet cultivars were arranged in a Randomised Complete Block design with six replications. The aim of the work was to study the root shape variability using an image analysis system and to relate root shape parameters [area (A, cm 2 ), maximum length (L, cm), maximum width (W, cm), average radial (AR, cm), radial variation (RV), circularity (Circ), elongation or the ratio W/L (El) and shape factor (SF)] with yield [fresh root weight (FRW), sugar yield (SY)] and quality [sucrose content % fresh root weight (SC), K, Na, D-amino N]. The main factors (year, site, cultivar) and their interaction had smaller effects on root shape parameters than on yield and its components. Cultivar affected only W but it had a significant impact on all quantitative and qualitative traits. No significant relationship between root W and yield or quality was found for cultivars. Significant, positive relationships between A and FRW or K in roots were found for the year × site × cultivar interaction. SC in roots was related with more rounded roots as revealed by the relationships between SC and Circ or El. Also, rounded roots were related with increased accumulation of K and decreased Na concentrations in sugar beets.

Cercospora and ramularia leaf spot are the most damaging fungal diseases of sugar beet in Europe. The aim of the current study was to evaluate the severity of fungal diseases and the efficacy of various fungicides and their doses in sugar beet crops in Lithuania. A short-term field experiment was carried out in 2012 and 2013 at Rumokai Experimental Station, Lithuanian Research Centre for Agriculture and Forestry on a moderately heavy loam HapliEpihypogleyic Luvisol (LVg-p-w-ha). Fungicides Impact (a.i. flutriafol), Opus (a.i. epoxiconazole), Artea (a.i. propikonazole + cyproconazole), Folicur (a.i. tebuconazole), Opera N (a.i. pyraclostrobin + epoxiconazole) were applied as a single application at the beginning of the disease occurrence (in August) and as a double application, with one spray at the beginning of the disease occurrence (in August) plus a second spray one month later (in September). The experimental results showed that the main fungal diseases in the sugar beet crops tested were Cercospora beticola and Ramularia beticola. Erysiphe betae was of minor severity. The application of fungicides significantly decreased the severity of cercospora and ramularia leaf spots by on average 19.8-81.8% and 71.8-91.8%, respectively. The most effective fungicides were Opus (a.i. epoxiconazole) and Impact (a.i. flutriafol). A single or double application of all the investigated fungicides had essentially the same effect. The most effective against powdery mildew was fungicide Opus, treated twice. Various active ingredients of the fungicides had insignificant effect on sugar beet yield and sucrose content in the roots. A single application of the fungicide Artea 0.5 L ha -1 (a.i. propiconazole + cyproconazole) and a double application Opus 1.0 L ha -1 (a.i. epoxiconazole) and Folicur 1.0 L ha -1 (a.i. tebuconazole) significantly decreased the content of impurities (potassium, sodium, alpha amino nitrogen) in the sugar beet roots compared with the untreated control treatment.

“…Moreover, one has to consider that harvest of sugar beet root in Harste was relatively early (Table 2) and that sugar beet root is suggested to increase yield with an extended growing period [22]. We, thus, conclude that, considering site-and year-specific circumstances, the difference between sugar beet root and silage maize DM yield can be somewhat lower.…”

Abstract:Since silage maize is the main crop grown for biogas production (biomass crop) in Germany; its increasing cultivation is critically discussed in terms of social and agronomical aspects. To investigate if sugar beet is suitable as an alternative biomass crop to silage maize; three-year field trials with both biomass crops in rotations with winter wheat (food crop) and continuous cultivation were conducted at three highly productive sites. Dry matter (DM) yield per hectare was measured via field trials whereas methane yield per hectare was estimated via a calculation. Higher annual DM yield was achieved by silage maize (19.5-27.4 t¨ha´1¨a´1) compared to sugar beet root (10.7-23.0 t¨ha´1¨a´1). Dry matter yield was found to be the main driver for the estimated methane yield. Thus; higher estimated methane yield was produced by silage maize (6458-9388 Nm 3¨h a´1) with overlaps to sugar beet root (3729-7964 Nm 3¨h a´1). We; therefore; classify sugar beet as a suitable alternative biomass crop to silage maize; especially when cultivated in crop rotations with winter wheat. Additionally; we found that the evaluation of entire crop rotations compared to single crops is a more precise approach since it includes rotational effects.
