Q12. Explain the features of commercial grain farming? 
A12. The features of commercial grain farming are-
1)    In commercial grain farming crops are grownfor commercial purpose.
2)   Wheat and maize arecommon commercially grown grains.
3)   Major areaswhere commercial grain farming is practised aretemperate grasslands of North America, Europeand Asia.
4)   These areas are sparsely populatedwith large farms spreading over hundreds ofhectares.
5) Severe winters restrict the growing seasonand only a single crop can be grown.

Q13 What is Mixed farming?
A13. Mixed farming- the land is used for growing food and fodder crops and rearing livestock.
It is practised in Europe, eastern USA, Argentina, southeast Australia, New Zealand and South Africa.

Q14. List the features of Plantation agriculture? A14. The features of the Plantation agriculture are-

4)    The development of a transport network is thus essential for such farming. 5)Major plantations are found in the tropical regions of the world.
6)    Rubber in Malaysia, coffee in Brazil, tea in India and Sri Lanka are some examples.

Q16. What is Agricultural development? How is agricultural development achieved in agriculture?
A16. Agricultural Development refers to effortsmade to increase farm production in orderto meet the growing demand of increasingpopulation.

Agricultural development can be achieved in many ways:-
1)    Increasing the cropped area.
2)   Increasing the number of crops grown.
3)   Improving irrigation facilities.
4)   Use of fertilizers.
5)   Using of highyielding variety of seeds.
6)   Mechanisation of agriculture should be implemented which is the use of more machines to increase the production of the crops.

Q17. How is agriculture in developed countries different from the developing countries?
A17. Developing countries with large populations usually practise intensive agriculture where crops are grown on small holdings mostly for subsistence. It is practiced in India ,Srilanka and Burma.
In the developed countries people usually practice commercial agriculture where crops are grown on large holdings mostly for export purpose. Commercial agriculture is practiced in USA, Canada and Australia .

In India agriculture is a primary activity because it is connected with extraction and production of natural resources. India is developing country where 75% of the population is engaged in the agriculture which include fishing, mining, gathering etc.

2)   Different crops are grown in different regions.
Different crops are grown in different regions because different crops require different climatic condition like temperature and rainfall for survival and growth.
