Morphological characteristics and nutritional value of purple-coloured storage roots of carrots protected with a biofungicide

Abstract

A b s t r a c t. A field experiment was conducted in 2013-2014. The experiment had a randomised block design with three replicates. The first experimental factor was two carrot (Daucus carota L.) cultivars, 'Purple Haze F 1 ' and 'Deep Purple F 1 ', and the second experimental factor was the application of the biocontrol agent Bioczos BR. In the control treatment, plots were sprayed with water. The aim of the study was to determine the effect of Bioczos BR on selected morphological traits and the nutritional value of purple-coloured storage roots of carrots. The analysed carrot cultivars differed considerably in root weight and length. Carrots of cv. 'Deep Purple F 1 ' had higher average root weight. Consistent changes were observed in the nutrient content of carrot roots. Bioczos BR contributed to an increase in the content of dry matter (by 14%), total sugars (by 28%), reducing sugars (by 31%) and nitrates (V) (by 32%) in carrot roots, in comparison with the control treatment.K e y w o r d s: carrots, morphology, nutritional value, storage roots

Effect of dolomite and pig manure on growth and production of carrots (Daucus carota)

“…Dolomite had few effects on taproot weights, likely due to environmental conditions, namely high rainfall at the beginning of the study, so most of the dolomite given was washed away by rainwater. In addition, rainwater also has a fairly wet pH, so the absorption of nutrients in the soil by carrot plants is not optimal (Gadomska et al 2018) so the impact on the interaction that occurs between pig manure and dolomite is not optimal in affecting the growth and production of carrot plants.…”

“…Carrot (Daucus carota L.) is an agricultural product in great demand by the people in Indonesia because it has beneficial vitamin and mineral contents (Stefl et al 2017) and a delicious taste. Carrot plants are classified as seasonal plants and are bush-shaped and can grow in the rainy and dry seasons (Gadomska et al 2018). The market demand for carrots is quite high.…”

Discriminating among Alternative Dressing Solutions for Cereal Seed Treatment: Effect on Germination and Seedling Vigor of Durum Wheat

“…Foreseeing the great potential of this technique, several fertilizer companies have been developing new seed dressing solutions for years. However, the limited literature describing the industrial seed application of non-microbial biostimulants evidenced contrasting results, caused by the plethora of active compounds used and the interactions among them and with the different growing conditions and crop species [38][39][40][41][42]. To better understand the effect and the efficacy of the different seed coating products on durum wheat, especially in terms of germination rate, germination speed and seedling vigor, we carried out several germination trials using different plant biostimulants.…”
