The correct answer is: d) All of the above.
Agroforestry is a land-use system in which trees or shrubs are grown deliberately alongside crops or livestock. It can be used to improve soil health, increase crop yields, provide additional income, and create a more sustainable agricultural system.
In Punjab, agroforestry is being promoted because it has the potential to address a number of the state’s agricultural challenges. For example, agroforestry can help to improve soil health by providing organic matter and nutrients to the soil. It can also help to reduce soil erosion and improve water infiltration. Additionally, agroforestry can help to increase crop yields by providing shade and windbreaks for crops. It can also help to improve crop diversity and reduce the risk of pests and diseases. Finally, agroforestry can provide additional income for farmers by selling timber, fruits, and other products from the trees.
Overall, agroforestry is a promising land-use system that has the potential to improve the sustainability of agriculture in Punjab. It is a system that combines the best of both worlds, trees and crops, and can provide a number of benefits for farmers and the environment.
Here is a brief explanation of each option:
- Option a: Agroforestry combines trees with crops. This can be done in a number of ways, such as intercropping, alley cropping, and silvopasture. Intercropping is a system in which trees and crops are grown together in the same field. Alley cropping is a system in which trees are planted in rows with crops grown in the alleys between the trees. Silvopasture is a system in which trees are grown in pastures with livestock grazing under the trees.
- Option b: Agroforestry provides additional income. This can be done by selling timber, fruits, and other products from the trees. Additionally, agroforestry can help to increase crop yields, which can lead to increased income for farmers.
- Option c: Agroforestry improves soil health. This is because trees provide organic matter and nutrients to the soil. Additionally, trees help to reduce soil erosion and improve water infiltration.
