Hydroponics is a suitable method of growing crops under controlled environmental conditions. But by continuous use of nutrient solution (NS), crop growth and yield may hamper for releasing some chemicals into the rhizosphere of plants by roots or leaves which is known as autotoxicity. To avoid yield reduction, every time farmers need to apply new NS and drain out the previously used NS which may cause of environmental pollution. I am fascinated to know the reasons for such yield reduction and recovering method for growing crops in hydroponic systems. During my doctoral course, I would like to find the suitable strategy for using electro-degradation for recovering the retarded growth of plants under electrical conductivity control systems. I also find the optimal intensity of LEDs for growing lettuce under autotoxicity. As I am university faculty member in my country, I will continue my research activities to identify autotoxic chemicals release by different plants grown hydroponically and possible ways to detoxify those substances.
