The greenhouse industry is the second largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment Agriculture has the ability to produce crops all year round, with the possibility of increased yield by adjusting the amount of carbon and nutrients the plants receive. [8]
Transformations are confirmed, from gene expression to production of the targeted proteins, and then phenotyped in the greenhouse and tested in replicated field trials. Once a trait is proven to be successful, we begin the more difficult and time-consuming task of transforming staple food crops, including soybeans, cassava, cowpea, and rice.
In the late 1960s, farmers began incorporating new technologies such as high-yielding varieties of cereals, particularly dwarf wheat and rice, and the widespread use of chemical fertilizers (to produce their high yields, the new seeds require far more fertilizer than traditional varieties [4]), pesticides, and controlled irrigation.

Southern Illinois is expected to see an increase from 43 inches currently to 48 or 52 under the different emissions scenarios. Precipitation is expected to fall in the summer across the entire state, while it will increase in Spring. The decrease in summer precipitation is expected to increase droughts in those months, impacting crop yields. [7]
Corn, one crop for which HYV seeds have been created. High-yielding varieties (abbreviated as HYVs) of agricultural crops are varieties of crops that are usually characterized by a combination of the following traits in contrast to the conventional ones: Higher crop yield per unit area; Higher quality of crops; Improved response to fertilizers
The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sectors contribute between 13% and 21% of global greenhouse gas emissions. [2] Emissions come from direct greenhouse gas emissions (for example from rice production and livestock farming). [3] And from indirect emissions.
In compost-heated greenhouses, heat and carbon dioxide are generated from a manure-based compost contained in a special chamber attached to one side of the greenhouse. [24] The New Alchemy Institute designed and built an experimental composting greenhouse in 1983 to research opportunities for the production of biothermal energy. [25]
