The practice of growing more than one type of crop on the same plot of land is called

Step 1: Analyze the question The question asks for the term describing growing more than one type of crop on the same plot of land at the same time.

Step 2: Explain the concepts

• Continuous cropping: growing crops on the same land year after year without a fallow period.
• Crop rotation: growing different crops on the same land in succession (one after another over seasons or years), not at the same time.
• Mixed cropping: growing two or more crops together on the same piece of land at the same time (e.g., maize, yam, and cassava on one farm plot).
• Mixed farming: combining crop cultivation with rearing of livestock on the same farm.
• Subsistence farming: farming on a small scale mainly to feed the farmer's family, with little or no surplus for sale.

Step 3: Match the definition "More than one type of crop on the same plot" describes mixed cropping. Crop rotation also involves different crops on one plot, but those crops are grown at different times, not together. Mixed farming involves animals as well as crops, so it does not fit.

Step 4: Answer The correct option is C. mixed cropping.

Tip: Link the words to their meaning:

• Mixed cropping = mixed crops together.
• Mixed farming = crops + animals.
• Rotation = crops take turns over time.

Note that this question is really an Agricultural Science topic, even though it was labeled Biology. You will likely meet it under crop production in Agric Science.
