It has become extremely difficult to guarantee the availability of safe food to an ever-growing population due to declining land resources, rising residual toxicity load, and declining safe water levels for agriculture and drinking. Besides, it has become difficult to maintain a sustainable production and productivity using the conventional agricultural system. In this context, hydroponic system has been a potential and widely accepted technology to confront the above issues. In addition to ensuring safe food, hydroponics also maximizes vertical space utilization, improves water efficiency, and reduces environmental problems related to crop production. The present experiment results revealed that vigorous growth of Palak crop under hydroponics system was observed with better quality produce. The average weight of Palak plant was harvested with 45.44 g per plant in the hydroponic system. Palak crop in the system produced profuse root mass with average root length of 16.00 cm. This paper deals with comprehensive study of hydroponic effect on growth and productivity of Palak crop.
