    The objective of this study was to investigate the effects of differentgrowing media on plant growth and nutrient contents of petunia (Petunia hybrida).The experiment was conducted in a chamber room under controlled conditions atthe laboratory. Seven different media (soil, 3:1 soil: peat (P1), 2:1 soil: peat (P2),3:1 soil: barnyard manure (BYM1), 2:1 soil: barnyard manure (BYM2), 3:1 soil:sugar beet pulp (SBP1), 2:1 soil: sugar beet pulp (SBP2)) were used as plantgrowing media. The experiment was ended after three months followingtransplanting of seedlings. Plant growth and flower parameters and macro-micronutrient contents were determined in harvested plants. The highest stem diameter,branch number, flower diameter, flower stalk diameter, plant fresh weight and plantdry weight were in 2:1 ratio of soil: peat mixture as 7.00 mm, 6.33, 8.91 cm, 3.59mm, 48.47 g and 4.52 g while the highest plant lenght, lateral branch number andflower number means were found as 27.43 cm, 24.67 and 24.67 in ratio of 3:1 soil:peat growing media respectively. The highest potassium, magnesium and zincmeans of plants were obtained as 6.6%, 2.2% and 32.50 mg kg-1 in soil: barnyardmanure (2:1) growing media while the highest phosphorus and calcium means ofplants were found as 0.27% and 4.5% in soil and peat growing media respectively.The highest iron and copper means of plants were determined as 231 mg kg-1 and32.50 mg kg-1 in ratios of 2:1 and 3:1 of soil: sugarbeet pulp growing mediarespectively.
