Answer:

Question 3.
In which season is cotton planted? What is its course of growth?
Answer:
It is planted in early spring. Cotton plants grow steadily and soon become bushes of 3 to 6 feet high. After about 2 months, they bear white or yellowish flowers which turn pink or red after a few days. The petals of the flowers fall, leaving behind tiny green seeds. This later grows into spherical shaped structure of the size of wallnut, which is called cotton ball.

As the cotton balls grow steadily the seeds and fibres grow inside. On maturing, the green balls begin to turn brown. On complete maturation, they become ready to burst open, exposing the white fibres. As the fibres dry in the sun, they become fluffy.

Question 1.
Write about debt problem of farmers in India.
Answer:
The Indian farmers are always in debt. The most farmers are permanent debtors. Almost all the time they have a sum of debt. Once the farmer falls into debt due to crop failure or low prices of crops or mal-practices of moneylenders; he can never come out of it.

In fact, a large part of the liabilities of farmers is ‘ancestral debt’. Thus along with his landed property, he passes on his debt to his successors.

There are main causes of farmers’ indebtedness:

1. Low earning power of the borrower
2. Use of loan for unproductive purposes
3. The excessively high rate of interest charged by the moneylenders
4. The manipulation of accounts by the lenders.
5. Drought or heavy rain;
6. Improper rates of farmers’ crops etc.

Question 2.
Describe about Rural livelihoods.
Answer:
People in rural areas earn their living in various ways. Some work in farms while others earn their livelihood in non-farming activities. Working on farms involves operations such as preparing the land, sowing, weeding and harvesting of crops. Rural people in different regions of the country grow different crops. However, we do find similarities in their life situations and in the problems that they face. Many depend on these lands for work as labourers.

Most farmers grow crops both for their own requirements and also to sell in the market, these are called big farmers. Some have to sell to traders from whom they have borrowed money, these are small farmers. Most small farmers, agricultural labourers, fishing families, crafts persons in the villages do not find enough work to keep them employed throughout the year.

Question 3.
What things effect the crop production negatively and how much do the small farmers suffer from the situation?
Answer:
If the seeds are not of good quality or pests attack their crop there can be a major crop failure. The crops can also be ruined if the monsoon does not bring enough rain. When this happens farmers sometimes are unable to pay back their and, for the family to survive, they may even have to borrow more money.

Soon the loan becomes so large that no matter what they earn, they are unable to repay. This is when we can say they are caught in debt. In recent years this has become a major cause of distress among farmers. In some areas this has also resulted in many farmers committing suicide.
