Solution(By Examveda Team)

The primary objective of greenhouse cultivation of vegetables is to get off season yield.
It maintains the yield by providing favourable growing conditions and protecting crops from un-favourable weather and various pests.
They offer a suitable microclimate for plants and make possible growth and fruiting, which is not possible in open fields. This is why a greenhouse is also known as a "controlled environment greenhouse".
