Question

name two crops produced in greenhouse with increased carbon Dioxide concentration​

Answer 1

Answer:

For most crops the saturation point will be reached at about 1,000–1,300 ppm under ideal circumstances. A lower level (800–1,000 ppm) is recommended for raising seedlings (tomatoes, cucumbers and peppers) as well as for lettuce production

Answer 2

Explanation:

Tomatoes are the most common vegetables grown in greenhouses, followed by cucumbers. Both are grown in the off-season (fall, winter, and spring) to take advantage of premium prices. Leaf and Bibb lettuces often are grown in the winter in cooler areas of the state.

Whereas normal air has a carbon dioxide concentration of around 400 ppm, most plants fare better in environments with carbon dioxide concentrations of between 600 and 1,000 ppm. When carbon dioxide is added to greenhouse air, it can help increase yields of tomato, cucumber and lettuce by as much as 25-30 per cent.
