Growth and blossoming of Lilium under various organic fertilizers . Seyedeh Mahboubeh Mousavi1 and Zahra Oraghi Ardebili2*

The present research was conducted to mitigate the environmental contamination and with the aim of evaluating the possible impacts of the application of sugarcane bagasse sewage sludge-based compost (BSC), vermicompost, and fish compost on different aspects of physiology, growth, and development of Lilliumlongiflorum var Ceb-Dazzle. The bulbs were planted in four different prepared soil mixtures with two levels (0% or 10%) of organic fertilizers including vermicompost, BSC, and fish compost. In contrast to vermicompost, the application of fish fertilizer delayed the germination reactions. BSC and particularly vermicompost had desirable promoting effects on leaf and root system, as opposed to fish compost.Increased proline, soluble carbohydrate, K, and Ca contents were observed in vermicompost and BSC treated samples. In contrast to the fish compost, the application of BSC and especially vermicompost had an improving impact on the blossoming time, qualities of flowers, and the postharvest life of cut flowers. In comparison with fish compost and BSC, vermicompost was the most effective fertilizer to promote growth and development of Lilliumlongiflorum. According to the obtained results, it seems that the horticulture utilization of BSC at this level at least does not have detrimental impacts on plant growth,whereas the application of fish compost, especially the one originated from the sea, may result inundesirable inhibiting effects most probably due to the high electrical conductivity (EC) and toxic metals or products.
