(b) Production of tomato.
(i) Sowing method: tomato seeds are first sown in a nursery (seed bed or seed box). Shallow rows (drills) are made and the seeds are drilled thinly, then lightly covered with fine soil and watered regularly. Sowing in the nursery gives strong, uniform seedlings before transplanting.
(ii) Transplanting: when the seedlings are about 4 to 6 weeks old and 10 to 15 cm tall with a few true leaves, they are watered, lifted carefully with soil around the roots, and transplanted to the prepared field in the cool of the evening at a spacing of about 60 cm by 45 cm. They are watered immediately after transplanting.
(iii) Varieties: examples of tomato varieties include Roma, Ronita, Ibadan Local, Beske and other improved and local varieties.
(iv) Harvesting: the fruits are ready for harvest about 3 to 4 months after transplanting. Mature fruits are picked by hand at the mature-green, pink or fully ripe (red) stage depending on the market; harvesting is done at intervals as the fruits ripen.
