Introduction to Agricultural Science as a School Subject

Agricultural Science is a school subject that teaches students about farming and the science behind the production of food, crops, and animals. It helps students understand how to grow plants, raise animals, and use the land wisely. The subject also covers the importance of agriculture to the economy and daily life. By learning Agricultural Science, students gain practical skills that can help them become future farmers, agricultural scientists, or food producers.

The subject is offered by students in Primary school and Secondary School as Agricultural Science.

Answers to Agricultural Science Exam Questions for SS2 Third Term

Answers to Section A (Objective Test)

The following table gives the correct answers to the objective section of Agricultural Science exam questions for SS2 Third term. If you are using a mobile device, hold the table and scroll to the right or left for a complete view.

So here you have the answers to the objective section of Agricultural Science Exam Questions for SS2 Third term. Use the comments section to let me know if you have any questions you would want me to clarify or discuss further.

Answers to Section B (Theory)

1a. With an annotated diagram describe the process of an egg formation in poultry animals, and a newly laid fertilized egg.

The egg formation in poultry takes place in the reproductive tract called the oviduct. It begins from the ovary where the yolk is released and travels through the oviduct, undergoing various stages:

• Infundibulum: Captures the yolk and fertilization occurs here if sperm is present.
• Magnum: Adds the thick albumen (egg white).
• Isthmus: Adds shell membranes.
• Uterus (Shell Gland): Adds the shell and pigment.
• Vagina: The egg is temporarily held before laying.

The diagram below shows the labeled parts of the oviduct and structure of the fertilized egg.

1b. Use the appropriate information to fill completely the farm animals’ reproduction stages.

2a. Differentiate between natural mating and artificial mating, stating four merits and four demerits of each.

Natural Mating: The male and female animals physically come together for mating.
Artificial Mating (Insemination): Semen is collected from the male and introduced into the female’s reproductive tract by a technician.

Merits of Natural Mating:

• Low technical skill required
• Ensures natural selection
• Minimal equipment required
• Cheaper in small-scale farms

Demerits of Natural Mating:

• Risk of disease transmission
• Limited offspring
• Injury risk during mating
• Not suitable for large herds

Merits of Artificial Mating:

• No disease transmission
• Efficient use of superior males
• Wider coverage of animals
• Offspring traits can be controlled

Demerits of Artificial Mating:

• Requires trained personnel
• More expensive
• Possible mishandling of semen
• Storage and transport challenges

2b. Explain the following types of natural mating:

• Pen Mating: One male is kept with a few females in a pen for mating.
• Stud Mating: A chosen male mates with selected females under supervision.
• Flock Mating: Males and females are allowed to mate freely in a flock or group.

2c. Identify any four signs of heat period in female farm animals.

• Swollen and red vulva
• Frequent urination
• Restlessness and mounting behavior
• Clear mucus discharge from the vulva

3a. What do you understand by reproductive hormones?

Reproductive hormones are chemical substances produced in animals that regulate sexual development, reproductive cycles, and fertility.

3b. Identify any six locations where reproductive hormones can be secreted in animals.

• Pituitary gland
• Ovaries
• Testes
• Hypothalamus
• Placenta
• Adrenal glands

3c. Outline any six reproductive hormones and one role of each.

• Follicle Stimulating Hormone (FSH): Stimulates development of ovarian follicles.
• Luteinizing Hormone (LH): Causes ovulation and formation of corpus luteum.
• Estrogen: Controls development of female secondary sexual characteristics.
• Progesterone: Maintains pregnancy.
• Oxytocin: Stimulates uterine contractions and milk ejection.
• Testosterone: Promotes male sexual characteristics and sperm production.

4a. Differentiate between macro nutrients and micro nutrients in crop production.

Macro Nutrients: Nutrients required in large quantities (e.g., Nitrogen, Phosphorus, Potassium).
Micro Nutrients: Nutrients needed in small quantities (e.g., Zinc, Copper, Iron).

4b. Identify any six ways plant nutrients can be lost.

• Leaching
• Soil erosion
• Crop removal during harvest
• Burning of vegetation
• Volatilization
• Runoff

4c. Effects of the following farming practices on soil:

• Clean Clearing: Destroys soil structure and leads to erosion.
• Bush Burning: Destroys microorganisms and reduces organic matter.
• Overgrazing: Leads to compaction and erosion.
• Continuous Cropping: Causes nutrient depletion.
• Tillage Practices: Can either improve or harm soil structure depending on method used.

4d. Four ways soil organisms improve soil:

• Decompose organic matter
• Improve soil aeration
• Enhance nutrient cycling
• Promote soil aggregation

5a. Differentiate between a forest and forestry.

Forest: A large area covered with trees and undergrowth.
Forestry: The science and practice of managing and conserving forests.

5b. Forest management practices:

• Afforestation: Planting trees on land previously without forest.
• Regeneration: Natural or artificial renewal of forest.
• Selective Exploitation: Harvesting only mature trees.
• Taungya Practice: Growing crops and trees together.
• Deforestation: Removal of forests without replanting.
• Pruning Practice: Cutting off unwanted branches to improve tree health.

5c. Four National Parks and Game Reserves in Nigeria:

• Yankari Game Reserve – Bauchi State
• Gashaka-Gumti National Park – Taraba/Adamawa
• Okomu National Park – Edo State
• Kainji Lake National Park – Niger/Kwara
