Use of Chlorella vulgaris and Ulva lactuca as Biostimulant on Lettuce

The important purpose of this work is to evaluate the biostimulant activity algae Chlorella vulgaris and Ulva lactuca extracts on crop plants Lactuca sativa, compare effect these two green plant growth development as a part sustainable production method show that can be promissory source for replacing chemical fertilization. study faces all phases growth, from germination seeds greenhouse treatment, matched with characterization both used lettuce plants. This meant define tool improved by more experiments studies in order suggest could ensure an adequate use organic fertilizer. After identification best concentration respective C. U. lactuca, experiment affirmed low (15% 25% lactuca) contributed satisfying nutritional profile, while high (75% conducive some parameters not suitable human diet health.
