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 (K 1), 2.5 g/l (K 2) and 5.0 g/l (K 3)] and gibberellic acid [0.005 g/l (G 1), 0.01 g/l (G 2) and 0.015 g/l (G 3)] 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 K 2 (2.5 g/l) plus G 2 (0.01 g/l) combination treatment. Plant height as well as chlorophyll content attained their greatest quantities under G 2 K 2 treatment. Dry matter, TSS % and antioxidant activity showed significant differences compared with control, G 1 K 1 and G 2 K 2 treatment showed the greatest sum of data. Fruit mineral content were also significantly affected by different treatments. Higher fruit potassium was recorded with G 3 K 3 treatment.
