In recent years, intelligent sensor techniques have achieved significant attention in agriculture. It is applied in agriculture to plan the several activities and missions properly by utilising limited resources with minor human interference. Currently, plant cultivation using new agriculture methods is very popular among the growers. However, the aeroponics is one of the methods of modern agriculture, which is commonly practiced around the world. In the system, plant cultivates under complete control conditions in the growth chamber by providing a small mist of the nutrient solution in replacement of the soil. The nutrient mist is ejected through atomization nozzles on a periodical basis. During the plant cultivation, several steps including temperature, humidity, light intensity, water nutrient solution level, pH and EC value, CO2concentration, atomization time, and atomization interval time require proper attention for flourishing plant growth. Therefore, the object of this review study was to provide significant knowledge about early fault detection and diagnosis in aeroponics using intelligent techniques (wireless sensors). So, the farmer could monitor several paraments without using laboratory instruments, and the farmer could control the entire system remotely. Moreover, the technique also provides a wide range of information which could be essential for plant researchers and provides a greater understanding of how the key parameters of aeroponics correlate with plant growth in the system. It offers full control of the system, not by constant manual attention from the operator but to a large extent by wireless sensors. Furthermore, the adoption of the intelligent techniques in the aeroponic system could reduce the concept of the usefulness of the system due to complicated manually monitoring and controlling process.

“…Therefore, the ideal pH values are 6.5 to 6.8. However, the optimum EC values of the nutrient solution lie between 1.5 and 2.5 dS m -1 (Calori et al, 2017). To replenish the nutrients and maintain correct pH and EC, the nutrient solution should be changed every 4 wk (Farran and Mingo-Castel, 2006;Mbiyu et al, 2012;Bag et al, 2015;Resh, 2016).…”

“…The pH of nutrient solution and water is also convenient to check. The optimal pH 5.5 to 6 provides maximum nutrient availability for plants (Calori et al, 2017), and if it exceeds 7.3, it can be reduced with a diluted phosphoric acid or sulfuric acid solution (Otazú, 2010;Resh, 2016 Table 2.

The global average potato (Solanum tuberosum L.) production is 17.4 t ha-1. Even using the same potato varieties, there is a large gap between higher yields and lower yields among countries. Potatoes are a cash crop and a significant part of the global diet. Therefore, low soil fertility, soil-borne diseases, poor water quality, and pests seriously affect potato production in developing countries. To improve potato quality and production, it is necessary for the modern world to improve its potato cultivation techniques. Aeroponics cultivation is an alternative technology of soilless culture for effectively adapting to areas of the world where soil and water are in critical condition. In aeroponic systems, plant roots are suspended in the open air under controlled circumstances to replace the soil with artificially provided foam or plastic stents. Moreover, the nutrient solution is spread through atomization nozzles. This review provides insights into the potential use of aeroponics in complementing potato production in developing countries. Moreover, in most developing countries, this technology should be adopted after deliberate consideration to increase potato production.

“…This alternative supply system can work well in countries where there is a lack of high-quality seed potatoes. For example, in Ethiopia, where 98.7% of seed potatoes come from the informal system and the formal system is in its early stage, 1.3% of healthy seed potatoes are supplied by such alternative system [9,11,14,16].…”

The potato has been a widely used vegetable crop in temperate countries for a long time. Its consumption and the area of its cultivation has increased significantly over the past decades in the tropics and subtropics as well. The main problems of potato producers in the tropics and subtropics are the unsatisfactory quality of seed potatoes, mainly derived from the informal seed supply system, and the insufficient availability and high cost of certified seed potatoes. The hope for improving this situation can be the application of soil-less technologies for minituber production under controlled conditions. This publication focuses on important advantages of the aeroponic system in the production of pre-basic seed potatoes in the tropics and subtropics. It also highlights some deficiencies that can be overcome with the involvement of several actors in the potato industry, including local universities and the private sector. It emphasizes that innovative aeroponic installations are an opportunity to increase the production of high-quality seed potatoes in the countries of the tropics and subtropics, which, in many cases, will result in less dependence on expensive imported seed potatoes, often from a different climate zone. The introduction of aeroponic installations conserves the shrinking natural soil and water resources and contributes to their protection.
