Cotton is a Fibre Crop. Cotton is a tropical crop grown in kharif season in semi-arid areas of the country. Cotton requires clear sky during the flowering stage.

India ranks second in the world in the production of cotton after China. Cotton occupies about 4.7 per cent of total cropped area in the country. There are three cotton growing areas, i.e. parts of Punjab, Haryana and northern Rajasthan in north-west, Gujarat and Maharashtra in the west and plateaus of Andhra Pradesh, Karnataka and Tamil Nadu in south. Leading producers of this crop are Gujarat, Maharashtra and Telangana Per hectare output of cotton is high under irrigated conditions in north-western region of the country. Its yield is very low in Maharashtra where it is grown under rainfed conditions.

Q8.

Which of the following is/are the advantage/advantages of practising drip irrigation?

  1. reduction of weed
  2. reduction in soil salinity
  3. reduction in soil erosion

Select the correct answer using the code is given below

 

a) 1 and 2 only
b) 3 only
c) 1 and 3 only
d) None of the above
Solution : c)
Unattempted. Explanation :-
  • Option C is the Correct Answer: Drip irrigation help control weed (due to localized application of water near the root of the plant) and soil erosion (due to slow but sustained release of water). 

Advantages and Disadvantages of Drip Irrigation: 

Advantages of Drip Irrigation:

1. Maximum use of available water. 

2. No water is available to weeds. 

3. Maximum crop yield. 

4. High efficiency in the use of fertilizers. 

5. Less weed growth and restricts population of potential hosts. 

6. Low labour and relatively low operation cost. 

7. No soil erosion. 

8. Improved infiltration in the soil of low intake. 

9. Ready adjustment to sophisticated automatic control. 

10. No runoff of fertilizers into groundwater. 

11. Fewer evaporation losses of water as compared to surface irrigation. 

12. Improves seed germination. 

13. Decreased to tillage operations. 

 

Disadvantages of Drip Irrigation: In spite of the fact that drip irrigation has so many potential benefits, they’re a certain limitation also, there are as follow: 

1. Sensitivity to clogging 

2. Moisture distribution problem 

3. Salinity hazards 

4. High cost compared to furrow. 

5. High skill is required for design, install and operation

Q9.

With reference to the Irrigation water management, consider the following pairs

  2. Bhungaroo - Rajasthan
  3. Arvary Pani Sansad - Gujarat

Which of the pairs given above is/are correct?

 

a) 2 only
b) 1 and 2 only
c) 2 and 3 only
d) None of the above
Solution : d)
Unattempted. Explanation :-
  • Option D is the Correct Answer: 
    • The Neeru-Meeru Programme launched by the Andhra Pradesh state government for the conservation of water.
    • Bhungroo is a water harvesting technique that uses an injection module to store excess rainwater underground. Farmers can then use the same water for irrigation during summer and winter. Bhungroo means “straw” in Gujarati and has been in use in Gujarat since 2002.
    • Arvary Pani Sansad in Alwar, Rajasthan have taken up constructions of various water harvesting structures such as percolation tank, dug-out ponds, check dams through peoples participation.

 

Q10.

Consider the following statements about the distribution of minerals in India

  1. India is the largest producer and exporter of mica in the world.
  2. India has deposits of low-grade iron ore.
  3. Major limestone producing states in India are Bihar, Jharkhand, and Odisha.

Which of the statement given above is/are not correct?

 

a) 1 only
b) 2 and 3 only
c) 2 only
d) 3 only
Solution : c)
Unattempted. Explanation :-
  • Statement 1 is Correct: Mica is a naturally occurring non-metallic mineral that is based on a collection of silicates. Mica is a very good insulator that has a wide range of applications in the electrical and electronics industry. It is used in toothpaste and cosmetics because of its glittery appearance. It also acts as a mild abrasive in toothpaste. India is one of the foremost suppliers of mica to the world. Mica-bearing igneous rocks occur in AP, Bihar, Jharkhand, Maharashtra, Rajasthan.
  • Statement 2 is Incorrect: India has deposits of high-grade iron ore. The mineral is found mainly in Jharkhand, Odisha, Chhattisgarh, Madhya Pradesh, Goa, Maharashtra, and Karnataka. 

Statement 3 is Correct: Limestone rocks are composed of either calcium carbonate, the double carbonate of calcium and magnesium, or a mixture of both. Limestone also contains small quantities of silica, alumina, iron oxides, phosphorus, and sulfur. Over three-fourths of the total limestone of India is produced by Bihar, Jharkhand, Madhya Pradesh, Rajasthan, Andhra Pradesh, Gujarat, Chhattisgarh, and Tamil Nadu.

Q11.

The highest proportion of the total water used in the country in which of the following sectors?

 

a) Industry
b) Domestic Use
c) Irrigation
d) Energy
Solution : c)
Unattempted. Explanation :-
  • Option C is the Correct Answer: Irrigation accounts for more proportion of water used than any other sectors in the country. India, being an agrarian economy, has always given high developmental priority to irrigation to increase agricultural production. Agriculture, thus, accounts for 89% of surface water and 92% of groundwater utilisation. The share of Domestic sector is 9% in surface water utilisation, whereas industrial sector uses 2% of surface water and 5% of groundwater, which is lesser than the share of agriculture/irrigation.
