Q.2. Describe the geographical conditions for growth of cotton. Name the major areas of its production. Why is West Bengal the leading producer of Jute, the second important fibre crop of India?
Which are the important fibre crops of India? Mention the major producing areas of each crop. Write about the geographical conditions required for the growth of the most important fibre crop.
Ans. Cotton, jute, hemp and natural silk are the major fibre crops of India. The geographical conditions required for the growth of cotton, the most important fibre crop of India are as follows : Cotton is a kharif crop and requires high temperature, light rainfall or irrigation, 210 frost free days and bright sunshine for its growth. Rainfall at the time of bursting of the cotton balls is harmful as it spoils the cotton balls. Cotton grows well in drier parts of the black soil area of the Deccan plateau. Black soil is also known as black cotton soil due to the fact that it is ideal for growth of cotton. The major cotton-producing states of India are Maharashtra, Gujarat, Madhya Pradesh, Karnataka, Andhra Pradesh, Tamil Nadu, Punjab, Haryana and Uttar Pradesh. Jute is the second most important fibre crop of India. West Bengal, especially the Hooghly basin of the state, is the leading jute-producing area of the country on account of the well drained fertile soil of the floodplain which are renewed every year. Also the climatic condition with high temperature during time of growth and sufficient availability of water have favoured jute cultivation in the Hooghly basin of West Bengal. Bihar, Assam, Orissa and Meghalaya are the other jute-producing states.
Q.3. What are the main cropping seasons of India? Distinguish between them.
Ans. There are three cropping seasons in India–rabi, kharif and zaid.
Q.4. Look at the picture carefully and answer the questions that follow :
(i) Name the crop shown in the picture.
(ii) State the climatic conditions required for cultivation of this crop.
(iii) Name the two major regions growing this crop.
(i) The crop shown in the picture is sugarcane.
(ii) The climatic conditions required for its growth : Sugarcane is a crop of tropical and sub-tropical climate. It grows well in hot and humid climate with temperature of 21oC to 270C and an annual rainfall between 75 cm and 100 cm. Frost is injurious for the plant. Heavy rainfall before ripening decreases sucrose content. Hence, frost-free weather, short, cool, dry winter during ripening and harvesting is favourable.
(iii) Uttar Pradesh and Maharashtra are two major producing states of sugarcane.
Q.5. Explain briefly any four features of intensive subsistence farming in India.
Ans. Four features of intensive subsistence farming in India are as follows :

Intensive Subsistence farming is dominant in West Bengal, Assam, Orissa, Bihar, eastern Uttar Pradesh and coastal areas of Andhra Pradesh, Tamil Nadu and Kerala. There is tremendous pressure on agricultural land in these areas.
(ii) Farmer and his family produce mainly cereal crops like rice and millets for subsistence and for local market.
(iii) Ceiling on ownership:- Now there is limit on the ownership a farmer can have land in his name.

Ans. Four fibre crops are :-
(iv) Natural silk
Natural silk fibre is not obtained directly from the crop. It is called sericulture. In this silk is obtained from cocoons of the silkworm fed on green leaves specially mulberry.
Q.11. Why has Indian agriculture started a declining trend in food production? Explain any four reason. [2010, 2011 (T-1)]
Ans. Due to the following reasons food production is declining :—
(i) There has been a gradual shift from cultivation of food crops to cultivation of cash crops, fruits vegetable, etc.
(ii) Area under food crop has reduced due to rapid urbanisation.
(iii) More areas are being demanded for housing, setting up industries. etc.
(iv) The productivity of land is also declining due to heavy use of chemical fertilizers and pesticides. The Green Revolution has outlived its utility.
(v) Natural calamities like drought and flood have become frequent. Monsoon is still vital for food production.
Q.12. Mention the geographical conditions for the growth of wheat. Name the major areas of wheat production. (2010)
Which is the staple crop in the northern and north-western part of India? Describe the temperature, rainfall and soil conditions required for its growth. Name the major areas of its production.
Ans. Wheat is the main food crop in north and north-western part of the country.
The geographical conditions favourable for growth of wheat are as follows :
(1) Temperature : Wheat is a rabi crop and requires a cool growing season. Average temperature should be between 10�C to 15�C at the time of sowing, but higher temperatures and bright sunshine is required at the time of harvesting for proper ripening of grains.
(2) Rainfall : Wheat requires moderate rainfall of 50 to 75 cm annually, evenly distributed over the growing season. A little winter rain before ripening helps in increasing the yield.
(3) Soil. Deep alluvial clayey soils of Northern Plains and even black soil of Deccan are suited for growth of wheat. There are two important wheat-growing zones in the country – the Ganga-Satluj plains in the north-west and black soil region of the Deccan. Punjab, Haryana, Uttar Pradesh, Bihar, Rajasthan and parts of Madhya Pradesh are the major wheat growing states.

(b) Tea bushes require warm and moist and frost free climate with temperature between 20oC to 300C and annual rainfall of 150 to 250 cm.
(c) Frequent showers evenly distributed over the year ensure continuous growth of tender leaves.
(d) Deep, fertile, well-drained soil, rich in humus and organic matter are ideal for its growth. Hence, gently rolling topography in uplands is favourable for its cultivation.
Four geographical conditions required for growth of sugarcane are :
