The correct answer is: a) Crops of different heights together.
Mixed cropping is a farming practice in which two or more crops are grown together in the same field. This can be done for a variety of reasons, such as to improve soil fertility, reduce pests and diseases, or increase crop yields.
There are many different ways to do mixed cropping. One common method is to plant tall crops, such as corn, in the middle of the field and shorter crops, such as beans, around the edges. This helps to shade the beans and keep them cool, while the beans help to fix nitrogen in the soil, which benefits the corn.
Another common method is to plant crops with different growth habits together. For example, you could plant a fast-growing crop, such as lettuce, with a slow-growing crop, such as tomatoes. This allows you to harvest the lettuce early in the season and still have the tomatoes to enjoy later.
Mixed cropping can be a very effective way to improve your farm’s productivity. It can also help to reduce your reliance on pesticides and fertilizers, which can be beneficial for the environment. If you’re looking for a way to improve your farm’s sustainability, mixed cropping is a great option to consider.
Here is a brief explanation of each option:
a) Crops of different heights together: This is the most common type of mixed cropping. It helps to improve soil fertility, reduce pests and diseases, and increase crop yields.
b) Crops of the same family together: This is not a good idea, as it can lead to problems with pests and diseases.
c) Crops of long and short durations together: This can be a good way to use the land more efficiently. However, it is important to choose crops that have similar water and nutrient requirements.
d) High-value and low-value crops together: This can be a good way to increase profits. However, it is important to choose crops that are compatible with each other.
