Status of Fe, Mn and Zn in red beet due to fertilization and environment

Abstract

Soil is a non-renewable resource, so it should be taken care of it. High quality food with sufficient yield for a growing human population can be produced only if plant nutrients are added to the soil by fertilizers to increase soil fertility, but the fertilizers have to be used economically, with the aim of raising the nutrient content available in the soil in order to meet plants' needs. The goal of the present investigation was to determine the effect of application of organic and mineral fertilizers as well as the effect of research environment on micronutrient content in red beet root. A field trial (2003)(2004)(2005) was set up in a hilly part of Croatia according to the Latin square method, with four types of fertilization (control, 50 t stable manure*ha -1

Yield and Quality of Beetroot (Beta vulgaris ssp. esculenta L. ) as a Result of Microbial Fertilizers

“…On balance, a general decreasing trend was recorded in the contents of the micronutrients analyzed (iron, manganese and zinc) with the NPK 5-20-30 fertilization (and by the application of high doses of potassium). This was certainly a result of antagonistic activities between the investigated elements and potassium (Petek et al, 2017).…”

“…-Yield (t/ha), -Water and dry matter content determined by drying the fresh plant material at a temperature of 105ºC to constant weight, -Content of vitamin C determined by using the Mury method (Vracar, 2001), -Protein content converted into the percentage of total nitrogen x 6.25 (Jekić et al, 1988), -Cellulose content determined by using the Hoffman method (Jekić et al, 1988), -Determination of the total minerals with the combustion of air dry materials at a temperature of 500 to 550°C to constant weight (Sarić, 1986), -Iron content using the atomic absorption spectrophotometry. The results obtained were analyzed using the appropriate descriptive statistical methods, the analysis of variance and the R statistical software.…”

Red Beet (<i>Beta vulgaris</i>) Impact on Human Health

“…This phenomenon was described by high mineral content in red beetroot. This opinion is difficult to accept because iron content in dried beetroot is about 170 mg/kg [72], and in the cited research rats received 68 µg of iron daily, which is too small to be the source of iron overload. The most likely explanation may lie in the influence of impact of other red beetroot compounds on iron assimilation.…”

Beetroot response to sodium chloride as a component of fertilizers

“…Beetroots can store a lot of sugar, which determines their nutritional value (Tretyakov, 2000;D'Egidio et al, 2019). The content of protein and non-protein nitrogen compounds, vitamins, macro-and micronutrients, and antioxidant activity all affect the quality of edible roots (Petek et al, 2017;Petek et al, 2019).…”
