The Effects of Sewage Sludge Applications on Growth, Yield and Flower Quality of Limonium sinuatum (Statice) under Salinity Conditions

In this study conducted in greenhouse conditions, the effects of sewage sludge application on plant growth, yield and flower quality of Limonium sinuatum (Statice) under salinity conditions were investigated. For this purpose, application of 25%, 50% and 75% sewage sludge doses and 50 mM and 100 mM salt treatment was preferred. Research was conducted as 3 replicates and according to two factor random plots experimental design and in such a way as to have 5 plants in each plot. During in the study, the number of the leaves, the number of flowers harvested per plant, flower peduncle length and thickness were determined. At the end of this study, the root length, the fresh and dry weight of upper parts of plant, the root fresh and dry weight were examined. As expected, while salt application negatively affected the vegetative growth parameters of the plant, yield and flower quality, the increasing sewage sludge doses affected all parameters examined during the research positively. In light of the findings of the current research, it has been determined that in the salty conditions the increasing sewage sludge application doses affected plant growth, yield and flower quality positively by removing the negative effect of salt
