1. Which of the following practices helps prevent soil erosion?
A. Overgrazing
B. Deforestation
C. Planting cover crops
D. Using chemical fertilizers
Answer: c) Planting cover crops
Rationale: Cover crops protect the soil by reducing erosion, improving
soil structure, and preventing nutrient loss.
2. Which of the following is an example of a monocot plant?
A. Tomato
B. Carrot
C. Rice
D. Apple
Answer: c) Rice
Rationale: Monocots are plants that have one cotyledon in their seeds,
such as rice, corn, and grasses.
3. What is an example of agroforestry?
A. Growing rice in flooded fields
,B. Planting crops alongside trees
C. Using synthetic fertilizers
D. Practicing monoculture farming
Answer: b) Planting crops alongside trees
Rationale: Agroforestry involves the integration of trees and shrubs
into agricultural landscapes to provide ecological and economic
benefits.
4. What is the primary benefit of mulching in agriculture?
A. Increases water evaporation
B. Controls pests and diseases
C. Improves soil structure
D. Reduces weed growth
Answer: d) Reduces weed growth
Rationale: Mulch helps suppress weeds by blocking sunlight and
preventing seed germination.
5. What is the main purpose of crop rotation?
A. To increase soil erosion
B. To reduce soil nutrient depletion
C. To encourage plant diseases
D. To increase pest population
, Answer: b) To reduce soil nutrient depletion
Rationale: Crop rotation helps prevent the depletion of specific
nutrients by planting different crops that require different nutrients,
enhancing soil health.
6. Which of the following is a characteristic of asexual reproduction in
plants?
A. Involves the union of sperm and egg cells
B. Results in genetically diverse offspring
C. Only one parent plant is involved
D. Requires pollinators
Answer: c) Only one parent plant is involved
Rationale: Asexual reproduction involves only one parent, and
offspring are genetically identical to the parent plant.
7. Which of these is a method for reducing water usage in agriculture?
A. Flood irrigation
B. Drip irrigation
C. Furrow irrigation
D. Spray irrigation
Answer: b) Drip irrigation
Rationale: Drip irrigation is more efficient in water usage, delivering
water directly to the root zone of plants with minimal evaporation.
A. Overgrazing
B. Deforestation
