The three-year experiment concerned the yielding and fruit quality of
three parthenocarpic cucumber cultivars grown in the open field, under
nonwoven PP cover, and in the PE tunnel. The tested cultivars were as
follows: Marinda F1 (pickling type with warted, coarse-spined
fruits), Othello F1 (pickling type with sof-spined fruits), and
Gracius F1 (slicing type with smooth fruits). The most abundant
vegetative growth was observed with plants in the tunnel where the thermal
conditions were best. All tested cultivars under that cover gave the
highest early and total marketable yield. Under nonwoven PP the yield was
lower but many times exceeded the one in the open. The best yielding
cultivar was Othello, which was slightly earlier than Marinda. The Gracius
cultivar was the latest to reach harvest maturity and could not utilize
its whole yielding potential in the accelerated growing. In respect of
fruit chemical composition no significant differences between the tested
cultivars were found. A tendency to lower dry weight and sugar content in
tunnels was observed.
