“…A study conducted in 1991-92 in Sardinia, Italy, by growing certain hybrid tomato varieties. The result stated that certain hybrid tomato varieties produced abundant and excellent commercial quality fruit in a very short time (Leoni et al 2008). In 2001, a University of Arizona study aimed to determine the effect of aeroponics on plants prized for the medicinal properties of their roots by growing echinacea and burdock.…”

This review paper describes a novel approach to plant cultivation under soil-less culture. At present, global climate change is expected to raise the risk of frequent drought. Agriculture is in a phase of major change around the world and dealing with serious problems. In future, it would be difficult task to provide a fresh and clean food supply for the fast-growing population using traditional agriculture. Under such circumstances, the soil-less cultivation is the alternative technology to adapt effectively. The soil-less system associated with the Hydroponic and Aeroponics system. In the aeroponics system, plant roots are hanging in the artificially provided plastic holder and foam material replacement of the soil under controlled conditions. The roots are allowed to dangle freely and openly in the air. However, the nutrient rich-water deliver with atomization nozzles. The nozzles create a fine spray mist of different droplet size at intermittently or continuously. This review concludes that aeroponics system is considered the best plant growing method for food security and sustainable development. The system has shown some promising returns in various countries and recommended as the most efficient, useful, significant, economical and convenient plant growing system then soil and other soil-less methods.

One of the crucial steps in the development of self-sufficient extra-terrestrial human colonies is water and biomass management. One of the attempts to simplify the treatment scheme is to directly implement greywater into soil-less cultivation as no greywater treatment unit would be necessary. In this case, the most essential key factor is the influence of surfactants. In this paper, an analysis of various experiment designs is investigated and shown. While full factorial design of experiment would require more than 500 000 tests, with duration of at least 30 days each, an approach to reduce this number to a total of 5 experiments is shown in this paper for initial experiments.

“…The number of tomato plants per unit area (square meter) tends to be normally set between 2 to 4 plants per square meter [17]. Some studies report more than 4 plants per square meter [23]. In this paper, we use the lower bound (2 plants per square meter) to maximize of reliability margin of numerical calculations.…”

The world’s growing demand for food can be met by agricultural technology. Use of artificial light to supplement natural sunlight in greenhouse cultivation is one of the most common techniques to increase greenhouse production of food crops. However, artificial light requires significant electrical energy, which increases the cost of greenhouse production and can reduce profit. This paper models the increments to greenhouse productivity as well as the increases in cost from supplemental electric lighting, in a situation where the greenhouse is one of the elements of a smart grid, a system where the electric energy market is dynamic and prices vary over time. We used our models to calculate the optimum values for supplemental light and the required electrical energy for HPS lamps in the greenhouse environment, using cherry tomato cultivation as a case study crop. We considered two optimization techniques: iterative search (IS) and genetic algorithm (GA). The two approaches produced similar results, although the GA method was much faster. Both approaches verify the advantages of using optimal supplemental light in terms of increasing production and hence profit.
