Vegetables SS2 Horticulture and Crop Production Lesson Note

Class: SS2

Subject: Horticulture and Crop Production

What are Vegetable Crops?

Vegetables are plants that we eat mainly for their vitamins and minerals. Unlike grains (like maize) which give us energy, vegetables protect us from getting sick. We eat different parts of them: the fruits (Tomato, Okra, Pepper) or the leaves (Spinach).

Tomato

Tomato is the “star” of the Nigerian kitchen. It is used in almost every stew and soup.

• Nursery: Don’t plant the seeds directly in the main farm. Start them in a Nursery Tray or a small seedbed.
• Transplanting: Move the seedlings to the main field when they are about 10cm to 15cm tall (usually after 3 to 4 weeks). Do this in the evening when the sun is down.
• Staking: Most tomato plants are weak. You must tie them to a wooden stick (stake) so the heavy fruits don’t touch the ground and rot.
• Harvesting: Pick them when they turn “pinkish-red.” Don’t wait until they are too soft, or they will burst before you get to the market.

Okra (Lady’s Finger)

Okra is a very hardy vegetable. It is easy to grow and produces fruits for a long time.

• Planting: Unlike tomatoes, we plant okra Directly into the soil. You don’t need a nursery.
• Soaking: To make the seeds grow faster, soak them in water for 24 hours before planting.
• Spacing: 60cm between rows and 30cm between plants.
• Harvesting: This is the secret to okra—harvest the pods while they are still “young and snappy.” If you wait too long, they become “woody” and hard, and nobody can eat them.

Pepper (Chilli and Bell Peppers)

Peppers give our food “life” and flavor. In Nigeria, we love the spicy “Ata Rodo” and the big “Tatase.”

• Nursery: Just like tomatoes, peppers need a nursery. They are very delicate when they are babies.
• Transplanting: Space them 50cm apart.
• Watering: Peppers love water but hate “flooding.” If the soil is too wet, the leaves will turn yellow and fall off.
• Harvesting: You can harvest them green or wait until they turn bright red for a sweeter, spicier taste.

Spinach (Green Leafy Vegetables)

In Nigeria, we have many types of “Spinach” (like Amaranthus or Efo Tete). These are the fastest crops on the farm.

• Planting: The seeds are very tiny. Most farmers mix the seeds with Dry Sand before scattering (broadcasting) them so they don’t grow too crowded in one spot.
• Thinning: If the leaves are too crowded, pull some out and eat them! This gives the remaining ones space to grow big leaves.
• Harvesting: You can start “thinning” and eating them after only 3 weeks. To harvest the whole plant, cut it near the ground, and it will often grow back again.

General Care for Your Vegetable Garden

1. Fencing: Goats and chickens love vegetables! You must build a small fence around your garden to keep them away.
2. Mulching: Because vegetables have soft stems, they dry out fast. Use dry grass to cover the soil to keep it cool.
3. Fertilizer: Use “Poultry Droppings” or well-rotted manure. Vegetables love organic food more than chemicals!
4. Pest Control: Watch out for “Leaf Eaters” (caterpillars). If you see holes in the leaves, pick the worms off by hand or use a neem-water spray.

Teacher’s Classroom Discussion

Ask the students: “If you have a very small balcony in an apartment, which of these four vegetables would be the easiest to grow in a plastic bucket?” (Answer: Pepper or Tomato—because they grow upwards and fit perfectly in a container).
