The correct answer is: Both 1 and 2.
Crop intensity is the number of crops grown in a year on a given piece of land. It is calculated by dividing the total area sown by the gross cropped area. The national average crop intensity in India is 1.39, which means that on average, 1.39 crops are grown per year on every hectare of land.
Haryana has the highest crop intensity in India, at 1.72. This means that on average, 1.72 crops are grown per year on every hectare of land in Haryana. This is higher than the national average of 1.39.
The main reason for the high crop intensity in Haryana is the use of modern agricultural practices, such as the use of high-yielding varieties of seeds, fertilizers, and irrigation. These practices have helped to increase the productivity of land in Haryana.
The high crop intensity in Haryana has a number of benefits. It helps to increase the production of food grains, which is important for meeting the food needs of the growing population. It also helps to increase the income of farmers, which can help to improve their standard of living.
However, the high crop intensity also has some drawbacks. It can lead to soil degradation, as the land is not given enough time to rest between crops. It can also lead to waterlogging and salinity, as the use of irrigation can lead to the accumulation of salts in the soil.
Overall, the high crop intensity in Haryana is a positive development. It has helped to increase the production of food grains and the income of farmers. However, it is important to manage the land carefully to avoid the negative effects of high crop intensity.
