THE EFFECT OF ORGANIC FERTILIZER ON PLANT DEVELOPMENT

The aim of this research is to expose the effects of organic fertilizers obtained from natural materials to plant growth. For this purpose three same pots and three plants were used. One of the pots was mixed with egg shell, one mixed with olive seed, and the other was mixed with untreated soil. Onion plant was planted to the pots and the same amount of water was given every day inthe evening. The changes that occurred in the fruit of the plants during the fourty days were measured and recorded in the table and the process was photographed and recorded. As a result of the research, maximum height increase was the egg shelled soil, while the least height increase was untreated soil. Several proposals on the research process have been introduced
