THE IMPACT OF FERTILIZATION AND HARVESTING TIME ON THE BIOCHEMICAL COMPOSITION OF CUCUMBER (CUCUMIS SATIVUS)

Abstract

The study analyzes the effect of fertilization and harvesting time on the biochemical composition of cucumber fruits. Cucumbers of the ‘Roliai’ H variety were grown in an unheated greenhouse at the Institute of Horticulture of LAMMC in 2023. Five fertilization variants were applied: complex and mineral fertilizers, biological preparations in different concentrations, and their combinations. Cucumbers were harvested on July 24, August 1, and August 8. The study examined the content of dry matter, soluble dry matter, and ascorbic acid in the cucumbers.
The research confirmed that harvesting time and the applied fertilizers influence the biochemical composition of cucumbers, and that proper fertilizer selection and harvesting time are essential for an optimal yield.
