The correct answer is: d) All of the above.
Government initiatives to improve agricultural productivity focus on introducing high-yielding varieties, promoting mechanization, and providing irrigation facilities.
Introducing high-yielding varieties of crops is one of the most effective ways to increase agricultural productivity. High-yielding varieties are bred to produce more food per unit of land than traditional varieties. They are also often resistant to pests and diseases, which can further increase yields.
Promoting mechanization is another way to increase agricultural productivity. Mechanized farming can help farmers to plant, cultivate, and harvest crops more quickly and efficiently. This can lead to higher yields and lower costs.
Providing irrigation facilities is also important for increasing agricultural productivity. Irrigation can help farmers to grow crops in areas where rainfall is limited. It can also help to improve crop yields in areas where rainfall is erratic.
All of these initiatives can help to improve agricultural productivity and increase food security.
