Project Execution – SS3 Horticulture and Crop Production Lesson Note (Third Term)

Project execution is the stage where a crop or horticultural plan becomes a working farm. It covers preparing the site, sowing seeds or transplanting seedlings, maintaining the field, managing nutrients and water, and monitoring the crop daily. Timing and careful records matter throughout.

Subject: Horticulture and Crop Production
Class: SS3
Topic: Project Execution (Practical Crop and Horticultural Projects)

Behavioural objectives

By the end of the lesson, students should be able to:

• explain why timing matters when executing a crop project;
• describe clearing, tillage and bed construction as parts of site preparation;
• distinguish direct sowing from nursery planting and state when to transplant;
• list the field maintenance practices: thinning, supplying, weeding, staking and pruning;
• describe how fertiliser and water are applied to a crop;
• state what to check during daily monitoring and why records must be kept.

What happens when a plan moves from paper to the field?

In our last lesson, we talked about planning. Now it is time for execution. This is where your “blueprint” becomes a real, living farm.

Execution is action, and it must not be rushed. In horticulture, timing is everything. If you plant too early, the sun might scorch your seedlings. If you plant too late, the rains might wash them away. This stage is where you show that you can manage living crops as a real farmer.

How do you prepare the site?

Before you bring out your seeds, you must prepare their “home.”

• Clearing: Remove weeds and old stalks. Be careful not to burn them! In sustainable farming, we prefer to chop them up and use them as mulch or compost.
• Tillage: This means loosening the soil. For horticultural crops like carrots or onions, the soil needs to be very fine and soft so the roots can grow easily.
• Bed construction: Most horticultural projects use “raised beds.” These help with drainage (so roots do not drown) and make it easier for you to walk between rows without stepping on your plants.

How do you plant and transplant?

This is the “birth” of your project.

1. Direct sowing: Some seeds, like maize or okra, are strong enough to be planted directly into the main field.
2. The nursery stage: For delicate crops like tomatoes, peppers or cabbage, we start them in a “nursery” or seed tray. This is like a baby’s room where they are protected from the wind and harsh sun.
3. Transplanting: When the seedlings have 3 or 4 “true leaves,” we move them to the main bed.
   • Tip: Always transplant in the late afternoon or on a cloudy day. This reduces “transplant shock” and gives the plant the whole night to settle in before the hot sun comes out.

How do you maintain the field?

Once the plants are in the ground, your job is to be their guardian.

• Thinning and supplying: If too many seeds grew in one spot, “thin” them out so they do not fight for food. If some did not grow at all, “supply” new seeds in those gaps.
• Weeding: Weeds are “thieves.” They steal the water and fertiliser meant for your crops. Keep your beds clean!
• Staking: For tall plants like tomatoes or yams, you need to provide a stick (a stake) for them to climb. This keeps the fruit off the ground where it might rot or be eaten by insects.
• Pruning: Sometimes, you need to cut off “sucker” branches or dead leaves. This tells the plant to put its energy into growing big, juicy fruit instead of extra leaves.

How do you manage nutrients and water?

• Fertiliser application: Do not just throw fertiliser anywhere. Use the “ring method” (placing it in a circle around the plant) or “side dressing.” If you are using a greenhouse, you might use fertigation (putting the nutrients in the water).
• Irrigation: Consistency is key. It is better to give a little water every evening than to flood the plant once a week. If the soil feels dry an inch below the surface, it is time to water.

How do you monitor the project and solve problems?

A good project manager visits their farm every single day. Look for:

• Pest damage: Are there holes in the leaves? Use neem oil or organic sprays immediately.
• Deficiency signs: Are the leaves turning yellow or purple? This might mean the plant is hungry for nitrogen or phosphorus.
• Record keeping: Every time you spray, weed or fertilise, write it in your project logbook. This “evidence” is what your teacher will look for during grading.

Project execution needs patience and observation. Farmers say the best fertiliser for a farm is the “shadow of the farmer.” This means the more time you spend on your farm, the better it will grow.

Evaluation

1. What is tillage, and why do carrots and onions need fine, soft soil?
2. State two reasons for using raised beds.
3. Give two crops that can be sown directly and two that start in a nursery.
4. When should seedlings be transplanted, and why is late afternoon or a cloudy day best?
5. Name four field maintenance practices and state the purpose of each.
6. Why must a student keep a project logbook?

Assignment

Describe the daily checks you would make on a school farm plot. For each check, state what you would look for and what action you would take.
