Practice of Vegetable Production and Management

The project cycle

A project has four parts that repeat: Plan, Do, Check, Improve. After Improve you go back to Plan, but now you are smarter. Each loop gives a better crop and a better lesson.

Plan: choose crop, plot and dates

Pick an easy crop for the season, such as spinach, radish or coriander. Measure the plot. Write the sowing date, expected harvest date, seed and tool list, and the cost. Set a small target, such as 2 kg of spinach.

Do: sow, water, weed, protect

Prepare the soil, sow at the right depth and spacing, water regularly, remove weeds and watch for pests. Use safe methods such as compost and hand-picking pests. Keep tools clean and put them back. Always wash hands after farm work.

Check and improve

Every week measure plant height, count leaves and note problems. Write them in your diary. Compare with the plan. At harvest weigh the crop, count cost and income, and find the profit. Then pick one thing to improve next time, such as more sunlight, wider spacing or earlier sowing.

Try it

Start a tiny project: grow coriander or radish in a pot or box for four weeks. Fill in a diary with date, height and what you did. At the end write one thing you would improve.

Key formulas and definitions

• Cycle: Plan → Do → Check → Improve → repeat
• Plan: crop, plot, dates, cost, target
• Check: measure, record, compare with the plan
• Profit = Income − Cost

Worked examples

Common mistakes

• Skipping the plan and sowing in a hurry.
• Not writing records, so you forget what happened.
• Stopping at harvest and never checking what to improve.
• Changing many things at once, so you cannot tell what helped.
