Effect of Different Nutrient Solutions and Percentage of Vermicomposte on the absorption of Nutrient Elements and Growth Characteristics of Potted Calla Lily (Zantedeschia pentlandii cv. Allure)

The effect of nutrient solutions on growth characteristics and nutrient elements concentration in leaf and root of potted Calla lily (Zantedeschia pentlandii cv. Allure ) was studied in a CRD_based split plot design with two factors, nutrient solutions and vermicompost in soilless media cultures. Results showed that application of different nutrient solutions and different levels of vermicompost significantly affected the studied traits. The highest leaf area was obtained in effect of nutrient solution 3× vermicomposte 15% with mean 67.33 mm2 , the highest of leaves fresh weight,  leaves dry weight were in effect of nutrient solution 2 vermicomposte15% with means 2.33 and 0.24 gr. The highest root wet weigh, root dry weight were gained in effects of nutrient solution 3× vermicomposte 15% and nutrient solution 1× vermicomposte 15% with means 7.76 and 2.03 gr. The gighest root length was related to nutrient solution 2× vermicomposte 15% with mean 32 cm. The highest number of flower was seen in nutrient solution 3× vermicomposte 15%. The highest number of tubers was obtained in effects of nutrient solution 2× vermicomposte 15% with mean 1.98 and the most chlorophyll index was in effects of nutrient solution 2× vermicomposte 15% with mean 43.53. In leaf of calla lily, nutrition solutions 2 and 3, vermicompost %5 and 15% have the most absorbance of macro and micro elements. Also, in media culture of calla lily, the highest absorption of macro and micro elements were observed in nutrition solutions 1 and 3 and vermicompost 10% and 15%.
