YIELD AND QUALITY OF ORGANICALLY PRODUSED TOMATOES DEPENDING ON FERTILIZATION AND GROWING OF THE SCHEME
Abstract
Abstract: The experimental work was carried out in the experimental field at the Technical university - Varna in the period 2014-2016. A determinate variety tomato Kopnej F1 was tested these biological products: Biosol, Biofa and Emosan. The aim of the study was to investigate the influence of organic products for fertilization and cultivation scheme on yield and quality of tomato grown in terms of organic farming.
Organic products have a positive impact on yield as the high index of earliness was given in Emosan + Biofa (48,0%), Emosan (46,0%) and Biosol + Biofa (43,5%). The effect of organic products on the formed early yield in variety Kopnej F1 is higher in the one-line cultivation scheme – 36,1 %, compared to two-line scheme – 34,0 %.
It was established a positive effect in nutrition with Biofa on the content of ascorbic acid in tomato fruits for both cultivation schemes. Higher content of solids in the one-line scheme of growing under basic fertilization with Biosol.
Keywords: organic products, yield, quality, scheme cultivation, index of earliness.
