The correct answer is: c) Simultaneously on the same land.
Intercropping is a farming practice in which two or more crops are grown together in the same field. This can be done in a number of ways, such as by planting the crops in alternating rows, in blocks, or in a checkerboard pattern. Intercropping can provide a number of benefits, such as:
- Increased crop yields: Intercropping can help to increase crop yields by making more efficient use of resources such as sunlight, water, and nutrients.
- Reduced pest and disease problems: Intercropping can help to reduce pest and disease problems by disrupting the life cycles of pests and diseases.
- Improved soil health: Intercropping can help to improve soil health by increasing organic matter content and reducing soil erosion.
- Increased biodiversity: Intercropping can help to increase biodiversity by providing habitat for beneficial insects and other organisms.
However, intercropping can also be challenging. It is important to choose crops that are compatible with each other and that will not compete for resources. It is also important to manage the intercrop carefully to ensure that both crops are able to thrive.
Option a) is incorrect because intercropping involves growing two or more crops on the same land, not on separate plots.
Option b) is incorrect because intercropping involves growing two or more crops simultaneously, not one after the other.
Option d) is incorrect because intercropping involves growing two or more crops in the same field for multiple years, not in alternate years.
