13. Which one of the following agricultural practices is eco- friendly?

Correct Answer: (a) Organic farming
Solution:Organic farming is a production system of crops which avoids the use of synthetic and chemical inputs like fertilizers, pesticides, growth regulators and livestock feed additives.

Principles of Organic Agriculture emphasise sustainability and responsibility across four key areas that are Health, Ecology, Fairness and Care.

  • Health: Organic agriculture prioritises the health of soil, plants, animals, humans, and the planet, avoiding practices and substances harmful to these interconnected systems.
  • Ecology: It aligns with natural ecological systems and cycles, working to protect and sustain the environment, including biodiversity, climate, and water resources.
  • Fairness: It fosters equitable relationships in production, distribution, and trade, ensuring justice and accountability for environmental and social impacts.
  • Care: Organic farming takes a precautionary and responsible approach, considering the well-being of present and future generations through transparent and inclusive decision-making.

14. Assertion (A): Insect resistant transgenic cotton has been produced by inserting Bt gene.

Reason (R): The Bt gene is derived from a bacterium.

Correct Answer: (a) Both A and R are true and R is the correct explanation of A
Solution:

Bt Cotton

  • Genetically Modified (GM) and pest-resistant Bt cotton hybrids have captured the Indian market since their introduction in 2002.
  • They now cover over 95% of the cotton area, with the seeds produced entirely by the private sector.
  • Maharashtra has the largest area under Bt cotton, followed by Andhra Pradesh, Gujarat, and Madhya Pradesh.
  • Punjab and Haryana are known for cultivating Bt cotton in the north. Bt stands for the bacterium Bacillus thuringiensis.
  • Bacillus thuringiensis produces a toxin called Bt toxin, which is detrimental to certain kinds of pests (bollworms) that infect cotton crops.
  • This trait of Bacillus thuringiensis is induced into cotton by genetic modification.
    • However, yields have decreased sharply over time due to other pest populations that Bt cotton could not control.

  • The Bt toxin controls only bollworms, while cotton attracts more than 100 pests.

    • Another concern with Bt cotton is that the bollworm may develop resistance, similar to what happened in China.

15. Assertion (A): In Australia, cattle rearing is done more for meat than for milk.

Reason (R): Australians are traditionally nonvegetarians

Correct Answer: (b) Both A and R are true but R is not a correct explanation of A
Solution:Assertion is correct, but reason is not the correct explanation of assertion but he statement is true.

In Australia farmers rear cattle for meat export, and most of the Australian people are non-vegetarian.

According to the Livestock census, India is

  • World’s highest livestock owner at about 535.78 million
  • First in the total buffalo population in the world – 109.85 million buffaloes
  • Second in the population of goats – 148.88 million goats
  • Second largest poultry market in the world
  • The second-largest producer of fish and also the second-largest aquaculture nation in the world
  • Third in the population of sheep (74.26 million)
  • Fifth in the population of ducks and chickens (851.81 million)
  • Tenth in camel population in the world – 2.5 lakhs

16. The high density of population in Nile valley and Islands of Java is primarily due to :

Correct Answer: (a) intensive agriculture
Solution:Due to availability of fertile alluvial soil intensive 17 agricultural practices was possible in the Nile river and islands of Java. So, in this regions high density of population is found.
Nile river
  • It is the longest river in the world.
  • It rises south of the Equator and drains into the Mediterranean Sea.
  • Its basin includes parts of Tanzania, Burundi, Rwanda, the Democratic Republic of the Congo, Kenya, Uganda, South Sudan, Ethiopia, Sudan, and the cultivated part of Egypt.
  • Two main branches
    • Blue Nile coming from the Ethiopian and Eritrean highlands (Source of 85% of total flow).

    • White Nile, coming from the Great Lakes region.

  • The White Nile meets the Blue Nile at Khartoum, the Sudanese capital.
  • The Blue Nile originates from Lake Tana in Ethiopia.

17. With reference to Indian agriculture, which one of the following statements is correct?

Correct Answer: (a) About 90 percent of the area under pulses in India is rainfed
Solution:In Indian agriculture about 90% of the area under pulse is rainfed, but pulses need less water for cultivation so, the production of pulse hampers.
About Pulses
  • Pulses are the edible seeds of plants in the legume family. They are grown in pods and vary widely in shape, size, and colour.
  • The United Nations Food and Agriculture Organization (FAO) recognises 11 types of pulses, including chickpeas, dry beans, dry broad beans, dry peas, cow peas, pigeon peas, lentils, bambara beans, vetches, and lupins.
  • Beyond being an essential source of protein for a significant portion of the global population, pulses also contribute to healthy soils and climate change mitigation through their nitrogen-fixing properties.
  • India is the leading producer of pulses, accounting for 25% of global production, the largest consumer, with 27% of world consumption, and a significant importer, representing 14% of global imports.

1. Arjun             2. Jaya

3. Padma         4. Sonalika

Which of these are of wheat?

Solution:Arjun and Sonalika are hybrid variety of wheat produced by Indian Council of Agricultural Research.
About Indian Council of Agricultural Research (ICAR)
  • The Indian Council of Agricultural Research (ICAR) is an autonomous organisation under the Department of Agricultural Research and Education (DARE), Ministry of Agriculture and Farmers Welfare, Government of India.
  • Formerly known as the Imperial Council of Agricultural Research, it was established on 16 July 1929 as a registered society under the Societies Registration Act, 1860, in pursuance of the report of the Royal Commission on Agriculture.
  • The ICAR has its headquarters in New Delhi.
  • The Council is the apex body for coordinating, guiding, and managing research and education in agriculture, including horticulture, fisheries, and animal sciences, throughout the country.
  • India has one of the largest agricultural systems in the world, with 113 ICAR institutes and 74 agricultural universities across the country.

19. Assertion (A): Eastern coast of India produces more rice than the western coast.

Reason (R): Eastern coast receives more rainfall than the western coast.

Correct Answer: (c) A is true but R is false
Solution:Assertion is true, but reason is false. The western coast receives more rainfall than eastern coast, but the temperature between 20-27°C, heavy clayed soil quality and rainfall is more suitable for rice cultivation.
Difference between Eastern and Western Coastal Plains
The Western Coastal PlainsThe Eastern Coastal Plains
NarrowerWider
Intersected by various mountains of Western ghats.Run continuously from north to south.
Rivers form estuaries.Rivers form wide deltas.
Favors the formation of harbors.Do not favor the formation of harbors as they have wide continental shelves.
