MULTIFACETED POTENTIAL OF K AND GA3 ON GROWTH, PRODUCTION AND QUALITY OF F1 HYBRID Cucumis sativus L. (cv. KUK-9)

Abstract

An experiment was conducted to evaluate the effect of different concentration and combination of potassium [1.0 g/l (K1), 2.5 g/l (K2) and 5.0 g/l (K3)] and gibberellic acid [0.005 g/l (G1), 0.01 g/l (G2) and 0.015 g/l (G3)] foliar application on growth characteristics, quality and yield of F1hybrid cucumber (cv. KUK-9).The results showed that the highest amounts for growth, biochemical attributes, fruit maturity, quality belonged to K2 (2.5 g/l) plus G2 (0.01 g/l) combination treatment. Plant height as well as chlorophyll content attained their greatest quantities under G2K2 treatment. Dry matter, TSS % and antioxidant activity showed significant differences compared with control, G1K1 and G2K2 treatment showed the greatest sum of data. Fruit mineral content were also significantly affected by different treatments. Higher fruit potassium was recorded with G3K3 treatment.
