Question

Green house crops such as tomatoes and bell pepper produce higher yields. This is due to.

• A. Tomatoes and bell pepper are not $C_3$ plants
• B. Due to diffused light in green house
• C. $C{O}_2$ is limiting factor to photosynthesis
• D. $C{O}_2$ enriched atmosphere leads to higher yield

Answer 1

Answer: (D)

$C{O}_2$ enriched atmosphere leads to higher yield

• Growing crops in greenhouse produce higher yields due to a lot of reasons like - temperature control, carbon dioxide factor, reduced pest and disease exposure and humidity.
• The concentrated carbon dioxide results in larger leaves, stronger plant stems and possible early flowering and fruiting.
• So the correct option is 'CO2 enriched atmosphere leads to higher yield'.
