INTRODUCTION: In many developing countries including India, agriculture still remains the primary occupation of the people. Agriculture in India is the means of livelihood for almost 70 per cent of the workforce in the country. It has, since ancient times, been India’s most important economic sector. India is an agricultural country. Two-third of its population is engaged in agricultural activities. Besides producing food grains, agriculture is also a source of raw material required for industries. Hence, we can say that agriculture has been a potent factor in promoting industrialisation at a global level. In addition, some agricultural products like tea, coffee, spices, etc., are exported and foreign exchange is earned for the country.
Agriculture is the oldest human activity. It was agriculture that brought man out of the forest. Over the years cultivation methods have changed significantly. These changes have been influenced by physical, environmental and technological know-how and sociocultural practices.

III. Short Answer Questions
1. What is agriculture?
Answer: Agriculture is the process of producing food, seed, fibre and other goods by the systematic raising of plants and animals.
2. What is primitive farming? Mention any two characteristics.
Answer: In this form of farming, farmers clear, slash and burn a small piece of land and grow on it cereals and other food crops to sustain themselves.
Two characteristics of it are:
i. Primitive tools such as a hoe, digging sticks and dao are used.
ii. No fertilisers or manure is used and hence the land productivity is low.
5. What is Zaid?
Answer: Zaid is a short season between the rabi and kharif seasons.
IV. Long Answer Questions
1. Which type of farming is ‘slash and burn’? Why is the land abandoned after a few years?
Answer: Primitive subsistence is also known as slash and burn farming.
In this particular type of farming, no fertilizers or manure is used and hence the land productivity is low. Primitive subsistence depends upon monsoon, natural fertility of the soil, and suitability of other environmental conditions. Therefore, in this type of farming, the land is abandoned after a few years so that the land can regain its fertility during that time and become suitable again for farming.
2. ‘Some pulses are known as leguminous crops.’ Why are they grown in rotation with other crops? [HOTS]
Answer: Crop rotation is a process that works to conserve soil. It is achieved by planting and growing a series of different crops in the same soil. Pulses are grown in rotation with other crops as they help in restoring soil fertility by utilising nitrogen from the air. This process prevents the overgrowth of pathogens and a lack of fertility in the soil, overall. Pulses need less moisture and can survive in dry conditions. The land therefore later can be used to grow other crops.
6. What are the main cropping seasons in India?
Answer: India has three cropping seasons. These are rabi, kharif, and zaid.
Rabi: The rabi crops are grown between October and December and are harvested between April and June. Wheat, barley, peas, gram and mustard are some important crops. Availability of precipitation during the winter months helps in the growth of rabi crops.
Kharif: Kharif crops are sown with the onset of monsoon in June and are harvested between September and October. Paddy, maize, jowar, bajra, tur (arhar), moong, urad, cotton, jute, groundnut and soyabean are some of the important crops.
Zaid: This is a short season between the Rabi and Kharif seasons. Crops produced are watermelons, muskmelons, cucumber, vegetables and fodder crops.
7. Discuss the importance of horticulture crops and production in India.
Answer: India is the second largest producer of fruits and vegetables. It produces tropical as well as temperate fruits. Almost 13% of the world’s vegetables are produced in India. It leads the world in the production of peas and cauliflower, is second in onion, cabbage, tomato, brinjal and fourth in potato production. Horticulture in recent years has gained importance as an important component of agriculture in the country and has proved to be an important contributor to the nation’s GDP. Some of the important horticulture crops in the country are mangoes, oranges, bananas, pineapples etc.
8. Mention any six institutional and technical reforms implemented by the Indian government in agriculture.
Answer: Six institutional and technical reforms implemented by the Indian government in agriculture are:
i. Subsidy on electricity, seeds and fertilisers to ensure that farmers continue to improve agriculture, consolidated and collectivised farms to make them economically viable.
ii. Widespread use of radio and television for acquainting farmers in new and improved techniques of cultivation.
iii. Crop insurance to protect the farmers against losses caused by crop failure.
iv. Special weather bulletins and agricultural programmes for farmers on television and radio.
v. Well-knit network of rural banking for farmers to help them get loans to modernise agriculture.
vi. Announcing minimum support price for the crops grown by farmers to check exploitation of farmers by middlemen and speculators.
9. What is the Green Revolution? What programmes were launched in the 1980s and 1990s for improvement of agriculture?
Answer: The Green Revolution was initiated to bring about an improvement in the field of Indian agriculture. The Green Revolution is a phrase generally used to describe the spectacular increase in the production of food grains in India.
By the 1980s and 1990s, it became very clear that what was required was a comprehensive land development programme that would comprise both institutional and technical reforms. Some of the programmes that were launched in the 1980s and 1990s for improvement of agriculture were:
Kisan Credit Card (KCC): It was an initiative to make sure that the farmers have access to credit easily and at an affordable rate.
Accident Insurance Scheme (PAIS): This was introduced to guarantee the farmers compensations if their crops fail due to accidents or natural calamities.
Minimum support prices (MSPs): The major objectives of this was to support the farmers from distress sales as well as to procure food grains for public distribution.
Additional/extra questions and answers/solutions
1. What is commercial farming?
Answer: Commercial farming is a type of farming that uses technology high yielding seeds, chemical fertilizers, insecticides and pesticides in order to obtain higher productivity and production.
2. Name some commercial crops?
Answer: Wheat, rice, tea, sugarcane and banana.
3. What are the prominent wheat growing zones in India?
Answer: The two prominent wheat growing zones in India are the Ganga-Satluj plains in the northwest and the black soil region of the Deccan.
14. What are the conditions required for the cultivation of rubber?
Answer: Rubber is an equatorial crop. It grows well in tropical and sub-tropical areas also. It requires a moist and humid climate with rainfall of more than 200 cm and a temperature above 25oC.
15. What are the conditions required for the cultivation of cotton?
Answer: This fibre crop grows well in the drier parts of the black cotton soil of the Deccan Plateau.
It grows well in tropical and sub-tropical areas. It requires 6 to 8 months to mature, with high temperature and high rainfall. It grows best with irrigated water. Almost 210 frost-free days and bright sunshine are required for its growth. It is a Kharif crop.
