Abstract
The objective of this study was to evaluate the physicochemical characteristics, biometric and productivity of beet cultivars. The experiment was conducted in random blocks with four repetition. The treatments were six beet cultivars: Maravilha, Merlot, Kestrel, Itapua 202, Chata do Egito and Tall Top Early Wonder. These cultivars were evaluated for plant height, leaf number, diameter and length of root, average mass of root and fresh weight of shoot, the root shape index, productivity, the soluble solids, titratable acidity, ratio, pH and anthocyanin content. The highest average root masses and productivity were observed for the cultivars Maravilha e Tall Top Early Wonder, being similar to Itapua 202 cultivars and the Boring Egypt. For quality characteristics there was no difference between cultivars for the soluble solids and pH, this was not the same behavior for titratable acidity and ratio. The highest anthocyanin content were observed in cultivars Merlot, Kestrel and Chata do Egito. The cultivars Chata do Egito presented the best productivity and quality characteristics, for the factors and elements of the elapsed year climate.
Highlights
The production of vegetables is an agroeconomic activity in which the application of technologies such as the use of fertilizers, fungicides and hybrid cultivars represent the difference between high and low productivity, determining the good or poor quality of the product, which ends up being reflected in the income of the producer
The cultivar Tall Top Early Wonder showed superior heights observed by Zárate et al (2008), who observed heights of 23.16 cm
The highest number of leaves was observed in the cultivars Merlot, Kestrel and Tall Top Early Wonder (Table 1). These results demonstrate that there are genetic differences between cultivars, with this increased number of leaves on plants with lower heights can result in a self shadowing on cultivating Kestrel, showing a reduction in vegetative development and productivity (Tullio et al, 2013)
Summary
The production of vegetables is an agroeconomic activity in which the application of technologies such as the use of fertilizers, fungicides and hybrid cultivars represent the difference between high and low productivity, determining the good or poor quality of the product, which ends up being reflected in the income of the producer. Helm] is a herbaceous biennial vegetable belonging to the family Quenopodiaceae, where it is classified into three types: olerácea beet, or table beet, sugar beet and forage beet, the table-top beet, due to the growth in consumption in the domestic market, where the largest producers in Brazil are the South and Southeast. This vegetable is native to temperate regions of Europe, North Africa and West Asia (Filgueira, 2013). The edible part is its tuberous root, which is globular in shape (Costa, Vasconcelos, Silva, & Ness, 2008), red to purplish-red in color due to the presence of the betalaine pigments, which are important antioxidants (Araújo Filho, Eidam, Borsato, & Raupp, 2011)
