Cilj ovog istraživanja bilo je ispitivanje uticaja pet tečnih i lako rastvorljivih sredstava za ishranu biljaka na prinos i svojstva u vezi sa prinosom kod zelene salate gajene u zaštićenom prostoru u toku zime. Bioactiv, Hascon M-10 AD i Herbagreen primenjeni su folijarno; Foliacon 22 je zalivanjem a Drin je korišćen na oba načina. Zabeleženi su značajno viši prinosi po biljci na svim ispitivanim tretmanima, izuzev na tretmanu Bioactiv. Uzevši u obzir prinos i druga ispitivana svojstva najbolji rezultati su postignuti primenom preparata Drin zalivanjem, te bi se ovaj tretman mogao preporučiti kod plasteničke proizvodnje zelene salate u toku zime.

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.
