Study of Zinc Content in Biofortified Tomato

Abstract

Abstract. The aim of this work is to study the content of zinc in tomato biofortified vegetables (peppers, eggplant, and tomatoes). Objectives of the study are: to determine the content of zinc in tomato vegetables during cultivation of which agronomic biofortification was applied using environmentally safe organic fertilizer of new generation -"Riverm"; to compare zinc content in biofortified vegetables with the content of zinc in samples of vegetables grown by standard conditions. This paper uses laboratory (physical) methods; definition of zinc content in vegetables was performed with the use of voltampermetric analyzer. The research results give us the right to conclude that the use of fertilizer "Riverm" during cultivation of sweet pepper, eggplant and tomatoes helps them to be enriched by zinc. Biofortified vegetables contain 6,60-8,59 % of zinc more than control samples. Grown vegetables become a readily available source of zinc for humans and contribute to overcoming the "hidden hunger" caused by deficiency of this essential micronutrient in food.

Studying the accumulation of nitrogenous substances in biofortified pumpkin vegetables

“…The advantage of the carried out research is its relevance to a new raw substance in Ukraine -biofortified pumpkin vegetables grown with the use of the organic, environment-friendly Riverm fertilizer. Thus, the obtained findings on the content of nitrogenous substances and, in particular, proteins and amino acids in melons, watermelons and pumpkins provide additional characteristics of the biofortified crop and complement the previous findings on the above mentioned fertilizer that increases the contents of iron, zink, copper and caratinoids in vegetables [28][29][30]. However, the peculiarities of nitrogenous substances accumulation have been analysed not in all pumpkin vegetables but only in melons, watermelons and pumpkins (2 varieties of each species).…”

“…In Ukraine, vegetables are biofortified with the liquid, organic, environment-friendly fertilizer Riverm [27] that is distinguished by a peculiar composition (microorganisms, enzymes and growth substances) and specific effect that leads to the natural accumulation of biologically active compounds in plants. The use of the above mentioned fertilizer contributes to the accumulation of a greater amount of zinc, carotenoids and iron in tomato and pumpkin vegetables [28][29][30]. Pumpkin vegetables (watermelon, melon and pumpkin) biofortified with special fertilizers are new raw food materials in Ukraine; therefore, any previous studies do not provide information on the accumulation of major nutrients, particularly nitrogenous compounds, in them.…”

The effects of zinc biofortification of seeds and NPK fertilizer application on the growth and yield of sesame (Sesamum indicum L.)

“…Developing biofortified crops can improve the efficiency of growth in these soils with depleted or very low mineral composition (Borg et al, 2009). Cakmak (2008) reported the daily requirement of zinc for different age groups (10 mg for children, 12 mg for women and 15 mg for men) whereas Pavlotska (2007) noted that nursing mothers require 25 mg per day of zinc. The objective of this study was to determine the effect of zinc and NPK fertilizer on the growth and yield of sesame.…”
