About this course

Tomatoes that sold for ₦8,000 a basket in August can sell for ₦60,000 in March, and the farmers who catch that swing are not lucky — they planned water, seed and timing months ahead. This course teaches vegetable farming as a business for the Nigerian market as it stands in September 2026: choosing between tomato, pepper, cucumber and leafy greens on capital and market, open field versus net house versus greenhouse with real 2026 costs, leasing land and securing water (borehole, solar pump, drip), hybrid seed and a nursery that survives, soil preparation and fertiliser rates, an irrigation schedule for dry-season farming from November to March, integrated control of Tuta absoluta, wilt, nematodes and whitefly with safe spraying and pre-harvest intervals, a low-cost greenhouse tomato and cucumber cycle with pruning and training, harvest and post-harvest handling that stops the 40 percent loss, selling into Mile 12, local markets, aggregators, restaurants and online buyers, and the full naira budget, cash-flow calendar and financing options — then a costed farm plan for your own plot as your project.

Reports from Mile 12 in Lagos in 2024 and 2025 put a 50 kg basket of tomatoes at around ₦5,000 to ₦15,000 in the June to August glut, and at ₦60,000 to ₦100,000 in the March to May peak. Same basket, same market, five to ten times the price, decided mostly by the calendar. That swing is the whole vegetable business in one number: the farmer who harvests in August works as hard as the one who harvests in March and earns a fraction. This lesson explains where demand comes from, why the price moves, who in the chain keeps money, why most first-time growers lose theirs, and the three production systems (open field, net house, greenhouse) on a capital ladder, so you can choose the rung you can afford.

What you'll learn

Course syllabus — 12 lessons

  1. Why vegetables, and why most new growers lose: the glut and the peak, who actually keeps the money, and the three ways to grow with an honest capital ladder14 min
  2. Choose your crop and your system: tomato, pepper, cucumber and leafy greens compared on capital, cycle, risk, water and market, and open field versus net house versus greenhouse in one decision table14 min
  3. Land and water: leasing a plot on paper, omo-onile and community rules, fadama, boreholes and solar pumps, storage, and the litres-per-day maths that decides whether your crop lives through February14 min
  4. Seeds and the nursery: hybrid versus open-pollinated, the varieties sold in Nigeria, the NASC tag and fake seed, raising seedlings in trays or beds, damping-off, hardening and the day to transplant14 min
  5. Soil, land preparation and planting: testing the soil, beds and spacing per crop, manure and NPK and urea rates with 2025 bag prices, mulch, stakes and trellis, and the first two weeks after transplanting14 min
  6. Irrigation and the dry-season calendar: why November to March pays, planting windows by zone, reading the NiMet outlook, a drip schedule in litres and minutes, fertigation basics, and getting the crop through harmattan and the March heat13 min
  7. Pests and diseases without poisoning anyone: Tuta absoluta, whitefly, aphids, wilt, blight and nematodes, scouting and IPM, pheromone traps and nets, registered products and banned actives, pre-harvest intervals, PPE and the spray record13 min
  8. The low-cost greenhouse: buy a kit or build a tunnel, what vendors quoted in 2025, drip and shade net, the tomato and cucumber cycle with training, pruning and pollination, yields honestly stated, and when a greenhouse does not pay13 min
  9. Harvest and post-harvest: maturity stage and timing, picking without bruising, grading, plastic crates against raffia baskets, shade and cooling, ColdHubs-type cold rooms, transport, and how to bring the 40 percent loss down on your own farm14 min
  10. Selling: Mile 12 and the wholesale trade, local market women, aggregators, restaurants and hotels, supermarkets, WhatsApp and online buyers, price discovery, truck-share maths, simple contracts, and when the farm gate is the right place to sell14 min
  11. The naira maths: the full cost of one acre of open-field tomato and of one greenhouse cycle, yield at conservative Nigerian figures, low and high price cases with the arithmetic shown, break-even, the cash-flow calendar, finance options and the loan scams14 min
  12. Papers, people and your project: CAC, farm records, labour and safety, a written land agreement, insurance, the cooperative and the extension officer, then the farm plan Part 1 to Part 6 and the go, wait or no-go decision14 min
