Explain the important characteristic features of Indian agriculture

Main characteristics of Indian Agriculture:-

1. The Indian agriculture is mostly rainfed. About two-thirds of the total cropped area still depends up on monsoon rains. In the rainfed areas, the agriculture is precarious and less productive.

2. About one-third of the total cropped area is cultivated with irrigation water. In the irrigated areas, the agriculture is productive and prosperous.

3. The average size of land holding is only 1.7 hectares. Small and marginal land holdings are predominant which account for more than three-fourths of the total operational holdings.

4. In view of high population pressure and low man-land ratio, the Indian agriculture is highly intensive, where two or three crops are cultivated in the same piece of agricultural land in an agricultural year.

5. Due to the agro-geographical conditions there are mainly two crop-seasons in India, namely Kharif (June to October) and ‘Rabi’ (November to March). The third crop season known as ‘Zayad’ is also grown after the Rabi in the months of April, May and June where irrigation is abundant.

6. In view of favourable geographic conditions, Indian farmers grow a variety of crops, both food crops and industrial crops.

7. The Indian agriculture is highly traditional, subsistent and food grains oriented and less mechanized.

8. Plantation crops like tea, coffee, rubber, coconut, sugarcane and other cash crops like cotton, tobacco, jute have also had a pride of place in the Indian agriculture. Even though, they occupy relatively a small area, their contribution in the total agricultural income is significant.

9. The modernization of agriculture consists of hybrid farming is also significant.

10. The average productivity of crops in India is very low.

What are the problems of Indian agriculture

The Problems of Indian agriculture:-

1. Indian agriculture has been facing many problems, due to which the agricultural productivity in India is very low in comparison with that of many countries in the world.
