Practical Agriculture and Project Work
What practical work assesses
Practical agriculture tests whether you can plan, carry out, record and evaluate a real farm activity - a vegetable plot, a poultry unit, a compost heap, a nursery, a soil-erosion trial or a livestock feeding trial. Marks come from correct technique, safety, accurate records and sound evaluation, not only from the final product.
Planning a project
A good project plan states the title, objectives, materials, methods, time plan, budget, expected results and evaluation criteria. Objectives must be measurable: not 'to grow tomatoes well' but 'to produce 40 kg of tomatoes from a 10 m × 5 m plot within 90 days'. Traps: vague objectives, no control or comparison, and no record of inputs or costs.
Carrying out and recording
Use correct technique: land preparation to a fine tilth, correct spacing and depth, timely watering and weeding, safe handling of tools and chemicals, and proper harvesting. Keep daily records: date, operation, materials used, labour hours, observations and problems. Take measurements (plant height, number of leaves, yield, weight gain).
Evaluating and reporting
Compare results with the objective and with a comparison plot. Calculate yield, cost and gross margin. Discuss problems (pests, drought, poor germination) and what you would change. Present a clear report with tables and conclusions.
Worked example
Project: compare mulched and unmulched cabbage plots, each 5 m × 2 m. Objective: 'to determine whether mulching increases cabbage yield'. Record water applied, weeding time and final head weight in both plots. Evaluate: if mulched yield is higher and watering less frequent, conclude mulching conserves moisture and recommend it - but note that results apply to this site and season.
