Purpose: Hydroponics, also known as controlled environment agriculture, is a method of cultivating plants and herbs without soil using mineral-supplemented solutions. Agriculture biotechnology enhances its wings on developing genetically modified plants for expanding crop yield and introducing characteristic features such as growing seasonal crops throughout the year, weather-resistant, and pest resistance. Compared to traditional agriculture, hydroponic cultivation yields high-quality crops with 90% more efficient use of water. Therefore, hydroponic cultivation could be considered a succeeding future of agriculture. In this context, understanding agriculture through the hydroponic route is vital for the efficient cultivation of crops. This review elaborates on the different classes of hydroponic systems and the factors that enable the systematic elements of the frame-up. Design/methodology/approach: The significant intent of this review is to provide information on distinct hydroponic systems. Findings: The present review reports a comprehensive discussion about the significance of the hydroponics system, its mechanism, nutrient solution preparation, types of hydroponic setup, and the challenges faced and would light up the knowledge in the same. Originality/value: This review focus on the current feasible hydroponic method of crop cultivation.

Purpose: In this project, the formulation of TiO2.Fe2O3 nanopaint was discussed. Design/methodology/approach: The paint was formulated in alkyd resin using ball milling process. Intermolecular bonding between TiO2.Fe2O3 and the alkyd resin was studied by Fourier transform infrared spectroscopy. The water contact angle was measured and it is found to be hydrophilic in nature. The prepared TiO2.Fe2O3 nanopaint disclosed good corrosion-resistant behaviour in acid treatment test. The inhibition efficiency was calculated to ensure the anticorrosive behaviour of paints. Findings: The recorded results reveal that, TiO2.Fe2O3 nanopaint has moderate solid content and mechanically low irregularities compared with bare steel. Corrosion resistance is high in nanoformulated paints and therefore it has high inhibition efficiency. The contact angle reveals the film is hydrophilic in nature which enhance the spreading rate of paints. Research limitations/implications: The method is not limited to TiO2.Fe2O3 nanopaint but is also suitable for the preparation of other nanomaterial-based paint. Originality/value: In this project, iron oxide and titanium oxide act as the corrosion inhibiting pigment.
