The Effect of Sea Lettuce (Ulva lactuca) Liquid Fertilizer and Zeolite Combinations on the Development of Cucumber (Cucumis sativus)

Abstract

The combinations of organic liquid fertilizer material obtained from sea lettuce (Ulva lactuca) and different concentrations of zeolite were applied to the cucumber (Cucumis sativus) plant in six treatments with three replicates each. The combinations of the experimental groups were as follows; control group, G1 group 180 g Z (Zeolite), G2 group 90 g Z + 1140 ml Liquid Fertilizer (LF), G3 group 180 g Z + 620 ml LF, G4 group 270 g Z + 310 ml LF, G5 group 620 ml LF. Except the control group, all zeolites were applied with the first dose of liquid fertilizer, and other liquid fertilizer doses were given in three periods, after germination, flowering and yield. While the lowest germination rate was in control group, the highest rate was in group with 60 g zeolite. While the lowest seedling weight was observed in group with 90 g zeolite + 1140 ml liquid fertilizer, the highest rate was in group with 180 g zeolite + 620 ml liquid fertilizer. While the highest cucumber weight was observed in group with 270 g zeolite + 310 ml liquid fertilizer, the lowest was in group with 620 ml liquid fertilizer. Therefore, it may be said that zeolite has positive effect on germination. On the other hand, liquid fertilizer and zeolite combinations may have positive effects on the weight of the cucumber seedling and yield.
