THE EFFECT OF USING SOME FILAMENTOUS GREEN ALGAE SPECIES AS FERTILIZER ON GERMINATION AND GROWTH

Abstract

In this study, 'Deepozym' branded organic liquid algae fertilizer and collected from Sapanca Lake were used in bean (Ada Beyazı), wheat (Nusrat) and corn (Ada 523) (Phaseoulus vulgaris L., Triticum aestivum L., Zeamays indentata Sturt.) cultivars grown in Sakarya province. Two macroalgae (Spirogyra cylindrica Czurda 1932 and Cladophora glomerata Linneus 1843) were turned into organic liquid fertilizers and used to observe the changes in the physiological and morphological parameters of the plants.

In our study, besides germination for corn, wheat and bean under controlled conditions, pot trials were carried out; In our experiment, control, nutrient solution, commercial algae fertilizer, prepared algae fertilizer, nutrient solution, and prepared algae fertilizer mixture forms were applied. From the moment that the examined seeds start to germinate, the vegetative index, SPAD and the stem, root and leaves of the plants at certain intervals in the laboratory environment; measured in changes in morphological parameters.

In our study, when the effects of fertilizer types were examined, it was observed that commercial algae fertilizer was more effective on plant varieties, and it was determined that the effect in other groups differed according to plant development stages. Although their germination development is close to each other, statistically significant difference between plant groups in Kjeldahl analyzes, while differences between fertilizer types were determined at a very significant level. In our study, it is recommended that the efficiency of the fertilizer obtained from the algae species we have prepared should be used with nutrient additions depending on the concentration level and plant varieties requirement.
