Concept:Growing the same single crop repeatedly on the same land year after year is known as monoculture.
Explanation:Monoculture is the continuous cultivation of only one type of crop on a particular piece of land over many seasons.
In this practice, the farmer does not change the crop grown on that land.
Mixed cropping, however, involves growing two or more different crops together on the same land at the same time.
Crop rotation is the practice of growing different crops in a regular sequence on the same land over successive seasons.
Shifting cultivation refers to clearing a new area of forest, farming it for a few years, and then moving to a fresh plot when soil fertility declines.
Since the question specifically describes growing only one crop year after year, the correct term is monoculture.
Answer:C. monoculture
