THE EFFECT OF LIQUID AND SOLUBLE FERTILIZERS ON LETTUCE YIELD

The aim of this study was to examine the effect of five liquid/soluble fertilizers on yield and yield contributing characters in plastic house grown lettuce. Bioactiv, Hascon M-10 AD and Herbagreen were splashed onto the plants; Foliacon 22 was applied within watering and Drin was used in both ways. The yield was significantly increased by all treatments, except for Bioactiv. Considering both the yield and other traits analyzed, the best results have been achieved by application of Drin within watering and it could be recommended for plastic house grown winter lettuce.
