Because of increasing human population and their food need the agricultural production increases, too. But meanwhile artificial fertilizer using and their negative effects to ecosystem are rising day by day. So, the scientist research different alternative solution for this pollution such as eco-friendly biofertilizer.Group of Cyanobacteria consists of photosynthetic prokaryotic microorganisms that has a highly diversity. Cyanobacteria can produce different metabolites that are valuable economically such as amino acids, proteins, vitamins etc. This study focuses the effects of different concentrations of Spirulina platensis (Gomont) Geitler extracts on the germination of lettuce seeds. For this purpose, root-stem length, lateral root number and wet-dry weight were investigated. The application of S5 (100% cell extract) showed an inhibitory effect on seed germination and so other parameters could not be measured. S2 (25% cell extract) and S3 (50% cell extract) applications had a positive effect on germination and seedling development in lettuce. As a result; cyanobacterial extract has positive effects on seed germination and plant growth-development and it is possible to produce a commercial and ecological biostimulant by developing different extract concentrations. And this biostimulant may be used instead of the other ecologically harmful artificial fertilizer. By the way; the large amount money that spends for the artificial fertilizer will be brought to the economy of Turkey.
