The correct answer is: All of the above.
Improved irrigation can enhance crop productivity by providing crops with the water they need to grow. Organic farming practices can enhance crop productivity by using natural methods to improve soil health and reduce the use of pesticides and fertilizers. Introduction of high-yielding varieties can enhance crop productivity by providing farmers with crops that are more productive than traditional varieties.
Here is a brief explanation of each option:
- Improved irrigation can enhance crop productivity by providing crops with the water they need to grow. Irrigation can be done through a variety of methods, such as canals, wells, and drip irrigation. When crops are well-watered, they are able to produce more food.
- Organic farming practices can enhance crop productivity by using natural methods to improve soil health and reduce the use of pesticides and fertilizers. Organic farming practices include crop rotation, cover cropping, and composting. These practices help to improve the soil’s ability to hold water and nutrients, which makes it easier for crops to grow. Organic farming also reduces the use of pesticides and fertilizers, which can harm the environment and human health.
- Introduction of high-yielding varieties can enhance crop productivity by providing farmers with crops that are more productive than traditional varieties. High-yielding varieties are often bred to be resistant to pests and diseases, and they can also be more tolerant of drought and other environmental stresses. When farmers plant high-yielding varieties, they are able to produce more food from the same amount of land.
In conclusion, all of the factors listed in the question can enhance crop productivity in Sikkim. By improving irrigation, using organic farming practices, and introducing high-yielding varieties, farmers can increase their yields and help to ensure food security for the population.
