The effect of nutrient solutions on the growth, development and flowering of calla lily was studied in a split plot design with completely randomized blocks design in soilless media cultures. The experiment was conducted with 16 treatments including four kinds of changed Quick nutrient solutions and four media cultures containing vermicompost and three replications and every replication included four pots. Results showed significant differences among different treatments regarding stem length, number of leaves, leaf area, number of flowers, spathe length, spathe width, root length, flowering period, pot life, amount of chlorophylls a, b, total and spathe anthocyanins. The highest number of leaves and the most amount of leaf chlorophylls resulted under the influence of nutrient solution 1 and vermicompost 5%. The highest root lenght resulted under the effect of nutrient solution 2 and vermicompost 5%. Treatment with nutrient solution 2 and vermicompost 15% showed the longest flowering period. Pot life of flower was longer than other treatments under the influence of nutrient solution 1 and without vermicompost. The highest number of flowers were seen as a result of nutrient solution 4 with vermicompost 5%. The amount of anthocyanins under the effect of nutrient solution 4 and vermicompost 10% was higher than other treatments. The largest stem diameter was obtained from nutrient solution 2 and vermicompost 15%. Also, it was concluded that nutrient solution 1 was more effective on vegetative characteristics of leaves because of having the most ammonium nitrate compared to other solutions and nutrient solution 2 had a significant effect on producing characteristics because of having the most potassium nitrate compared to other solutions.
