“…In this system, crops can be cultivated in deserts and infertile lands, such as mountainous regions [179][180][181]. Hydroponics is a suitable cultivation method in congested urban centers where there is a shortage of vacant land for cultivating food [177,[181][182][183][184].…”

“…Plants in hydroponic systems are grown without soil. The plant's roots are submerged in a nutrient-rich solution [177][178][179][180][181][183][184][185][186][187]. The amount of nutrient solution is calculated; therefore, the amount necessary for the plant's growth is delivered to the roots [181,183,186].…”

“…Plant roots can be supported and maintained in hydroponic systems by peat, moss, perlite, rock wool, vermiculite, sand, gravel, or soil pellets. Hydroponic systems can be categorized into the following types: (1) the wick system; (2) the drip system; (3) the ebb and flow or flood and drain system; (4) the nutrient film technique (NFT); (5) deep flow technique (DFT) pipe system; (6) the floating raft system; and (7) the column system [177,178,180,184,185]. The mentioned systems equipped with grow lights can be assembled on rooftops in greenhouses to cultivate crops intensely.…”

“…In a drip system, water and nutrient solutions can be delivered to plants using little hoses and drip emitters [177,180,185,188]. This system pumps water and nutrient solutions directly from the tank to each plant's root area in the right proportion [177,184,188,189]. Typically, plants are cultivated in a growing medium so the nutrient solution and water drip down gradually [177,180].…”

It is evident that, due to population growth, future urbanization and urban growth are inevitable. It is estimated that the food supply demand of future urban centers will grow, which will place an additional burden on the agriculture sector to produce more food. It is projected that securing the food supply chain for future urban centers will be a challenge. Urban agriculture can be regarded as a remedy for possible future challenges that the global food system will face. It might be able to reduce the future burden on the agriculture sector. This research proposes that urban rooftop agriculture, as a subset of urban agriculture, can produce local fresh food in dense urban environments. The principal aim of this research is to suggest a series of design recommendations for architects interested in designing residential buildings capable of rooftop food production. This research attempts to highlight the specific design recommendations and the principal limitations regarding designing residential rooftop farms. To extract the data for developing the proposed design recommendations and limitations, a review of the literature within the fields of urban agriculture, building-integrated agriculture, and horticulture was conducted. Based on the literature review results, this research suggests that the following three types of farming methods can be developed on residential rooftops: (1) open-air rooftop food production, (2) “low-tech” rooftop greenhouses, and (3) “high-tech” rooftop greenhouses. In addition, factors that can be considered principal limitations are suggested. In sum, this research proposes that current and future residential buildings can be designed so that their rooftops are utilized as farms. In this way, such buildings can contribute to delivering local fresh food to current and future metropolitan dwellers.

“…Non-soil growing medium can be used in hydroponics to give roots mechanical support so they can sustain the plant's weight and stand upright. In hydroponics, media such as gravel, peat moss, river rock, sand, oasis cubes, rockwool, floral foam, perlite, vermiculite, coir, coco-peat, and sawdust are frequently used 52 . Sub-irrigation and top-irrigation are the two basic variations for each medium.…”

Rice (Oryza sativa L.) is the most important staple crop. Rice is a source of essential vitamins such as vitamin C and B6, carbohydrates and other nutrients such as selenium and phosphorous. About 90% of world’s rice are cultivated in Asia and Africa. China is the leading producer. It fulfills 70% income and nutrition needs of Asian population. Rice can be the potential solution to hunger and malnutrition, especially in poor, developing countries. The methods of rice growth are transplanting and cultivation media, grow in hydroponic condition and grow in soil. The production of rice is impacted by biotic stressors, which are present in a wide range of agro-climatic conditions around the world. Multiple diseases can be brought on by biotic pressures caused by climate change. To mitigate the impact of climate change and enhance rice cultivation unique germplasms are being cultivated. This review presents unique germplasm of rice and their cultivators, methods of rice cultivation, disadvantages of rice cultivation for research purpose and diseases that affect rice.

This study evaluates the efficacy of a nutrient film technique (NFT) hydroponic system in phytoremediation of nitrate‐nitrogen contaminated wastewater using six plant species: vetiver grass (Chrysopogon zizanioides), golden pothos (Epiprennum aureum), crotons (Codiaeum variegatum), arrowhead plant (Syngonium podophyllum), spinach (Spinacia oleracea), and brinjal (Solanum melongena). This study examines how well different plant species remove nitrate‐nitrogen from wastewater in an NFT hydroponic system. It finds that all plants, but especially money plant and arrowhead plant, successfully lower nitrate levels at influent concentrations of 30 and 90 mg/L. The wastewater had average pH values of 5–6.5, temperature values of 24°C–25°C, electrical conductivity values (EC) of 1.5–2 mS/cm, and total dissolved solids (TDS) between 1062 ± 199.3 and 1400 ± 124.16 mg/L. The system for golden pothos (70.94%–90.3%), crotons (62.5%–83.1%), arrowhead plant (67.25%–90.03%), vetiver grass (45.42%–83.1%), spinach (47.15%–81.71%), and brinjal (59.52%–83.38%) has shown excellent biochemical oxygen demand (BOD5) elimination efficiency. These results suggest that nitrate‐nitrogen contaminated wastewater can be effectively cleaned up by NFT hydroponic systems, which employ certain plant species.
