Agricultural Practices and Land Use Questions

Multiple choice

How do mulch plants help in preventing erosion?

  1. By reducing run-off erosion

  2. By decreasing soil loss

  3. By checking the flow of water

  4. By reducing soil moisture evaporation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mulch plants prevent  soil erosion by reducing the soil moisture evaporation.

Multiple choice

What does contour terracing involve?

  1. Construction of small basins

  2. Construction of channels at suitable intervals

  3. Preparation of furrows and ridges in the field

  4. Planting the crops in strips
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Contour terracing involves construction of channels at suitable intervals.

Multiple choice

A practical method to control soil erosion is

  1. increasing the population of birds

  2. building more water bodies

  3. increasing the population of plants

  4. decreasing the velocity of wind
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Humans can increase the population of plants by afforestation and controlling soil erosion.

Multiple choice

Which of the following is correct about plantation farming?

  1. It covers large tracts of land and uses capital intensive inputs with the help of migrant labourers.

  2. High doses of biochemical inputs and irrigation are used for obtaining higher production in this type of farming.

  3. The degree of commercialisation of this type of agriculture varies from one region to another.

  4. The main characteristic of this type of farming is the use of higher doses of modern inputs such as use of HYV seeds, fertilisers etc.

  5. Land holding size in this type of farming is uneconomical due to 'right of inheritance' laws.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is correct. It is a commercial farming where a single crop is grown over a large area and thus, it covers large tracts of land. Since the owner is a separate entity, it uses capital intensive inputs with help of migrant labourers.

Multiple choice

The leguminous plants (legumes or dals) are important in agriculture because they

  1. have a short life

  2. are disease-resistant

  3. help in nitrogen economy of the plant

  4. need very little water to grow

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Leguminous plants have symbiotic relationships with Rhizobium bacteria in their root nodules, which convert atmospheric nitrogen into ammonia that plants can use. This nitrogen fixation reduces dependence on external fertilizers and improves soil nitrogen content for subsequent crops. The other options (short life, disease resistance, low water needs) are not universal characteristics of legumes.

Multiple choice

What is mixed farming?

  1. Collective farming

  2. Farming coupled with animal husbandry

  3. The combination of farming and industry

  4. The growth of two crops simultaneously

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mixed farming combines crop cultivation with animal husbandry (livestock rearing). This integrated approach optimizes land use - crops provide feed for animals, and animal waste fertilizes crops.

Multiple choice

What advice would you give to a farmer whose agricultural land is reported to be nitrogen-deficient?

  1. To cultivate a pulse crop in the field

  2. To cultivate cereal crop in the field

  3. To burn the debris present in the field

  4. To leave the field uncultivated for one season

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pulse crops (legumes like beans, peas) have nitrogen-fixing bacteria in their root nodules. They convert atmospheric nitrogen into soil nitrogen, naturally replenishing nitrogen-deficient soil.

Multiple choice

What is hydroponic farming?

  1. Cultivation of crops in nutrient solutions

  2. Farming without water

  3. Only mechanised farming

  4. Farming only with genetically modified seeds
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydroponics is a type of horticulture which involves growing plants without soil. Instead, plants are grown in a water-based, nutrient-rich solution that provides all necessary minerals directly to the roots.

Multiple choice

Which of the following methods are used to restrict soil erosion? A. Ploughing along contour lines B. Strip cropping C. Jhumming D. Mixed farming

  1. A and B

  2. A and C

  3. B and D

  4. B and C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ploughing along the contour lines can decelerate the flow of water down the slopes (contour ploughing). Large fields can be divided into strips. Strips of grass are left to grow between the crops. This method is called strip cropping.

Multiple choice

Which of the following statements is/are correct?

a. Farm forestry is a term applied to the process under which farmers grow trees for non-commercial purposes on their farm lands. b. Agro-forestry is the raising of trees and agriculture crops on the same land inclusive of the waste patches. c. Community forestry involves the raising of trees on public land such as temple land, roadside, canal bank, strips along railway lines and schools, etc.

  1. a only

  2. b only

  3. c only

  4. b and c

  5. a, b and c
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This is the correct answer as both the statements b and c are correct.

Multiple choice

Which of the following options is/are the advantages of sustainable agriculture?

  1. Only (a)

  2. Only (a) and (b)

  3. Only (b)

  4. Only (b) and (c)

  5. (a), (b) and (c)
