In order to study growing medium to replace peat in float system for improving germination and seedling production, an experiment was conducted in tobacconursery field. The treatments were peat, vermiculite, field soil, manure, sand, tree cortex compost and tea residue. There were significant differences between growing mediums in terms of germination percentage, germination rate, germination vigor, seedling length vigor, seedling weight vigor, collardiameter, radicle dry weight and seedling dry weight. The highest germination percentage, germination rate, germination vigor and seedling length vigor were observed in treatment of peat 50%+vermiculite 25%+field soil 25%. The highest collar diameter, radicle dry weight, seedling dry weight and seedling weight vigor were found in treatment of tree cortex compost 50%+ field soil 25%+ manure 25%.
