Abstract
Organic media physical and chemical properties are suitable for growing seedling. It is not is low cost for additional chemical
substances. In NP2O5K2O additional media M5 compared to organic media. The purpose of this study was to determine; the
use of different growing media for organic production of tomatoes and peppers seedling quality characterictics. The trial was
conducted the year 2010 in the greenhouse of Organic Agriculture Program of Arslanbey Vocational School of Kocaeli
University. In this research M4 containing peat-stable manure-perlite, M5 containing peat-sand-NPK, M6 containing peatstable manure and M8 containing peat gave positive results in tomato and pepper seedling cultivation. The quality of tomato
and pepper seedling measured values and there were a difference between different growing media statistically at p<0.05
level. However, the width of cotyledons of pepper with different growing medium did not differ statistically.
