Influence of organo mineral fertilizers on yield and mineral composition of horseradish (Armoracia rusticana Ph. Gärten, B. Mey et Scherb)

Abstract

Horseradish (Armoracia rusticana Ph. Garten) is a perennial plant of the family Brassicaceae. The root contains high levels of vitamin C, important minerals such as potassium, magnesium, calcium, phosphorus and iron, but also glucosinolates, glycosides, gluconasturtiin, sinigrine, asparagine, glutamine, oxidaseses and peroxidases. It is being cultivated for its rhizome, and the annual sprouts are used for reproduction. Plant biostimulators are non-toxic substances mostly of natural origin which contribute to the stimulation of physiological processes inside the plant. In our research we used an autochthonous variety Ludbreški horseradish, the aim of the study was to determine the impact of organic mineral fertilization on plant growth and the yield and mineral content in the horseradish rhizome. The experiment has been set randomly in blocks, in four repetitions using various types of organic mineral manures of good biostimulating effect (Biotech NPK 3:10:5 S+2 MgO and combined with Grena Biosprint Calcio NPK 9:1:1aminoacids; Grena Biobase NPK 3:8:8; Grena life NPK 4:6:10 S+2 MgO). Observing all the obtained results of this research, in certain variants of organo-mineral fertilization, a positive influence of organo-mineral fertilizers in relation to the control can be determined.
