Land Preparation for Tomato Cultivation

Land clearing is done manually with cutlass, ridges is made with hoe, or can be prepared by ploughing, harrowing and ridging.

Method of Propagation

Propagation is by seed planted either directly or first in nursery and later transfer to the field. The planting could be by drilling or broadcasting.

Soil Requirement

It does best in a rich drained loamy soil.


Tomato is a warm season crop and does best under dry condition. Annual rainfall is 750mm. Temperature is between 20ºC to 25ºC.

Planting Date

Early September to October

Seed Rate

5-10kg of seeds/ha

Nursery Practices

It is done on ground, beds or seed boxes. Seeds are sown in drill 5cm apart and 2.5cm deep Shading, mulching, weeding and watering are done. Nursery last for 3 weeks when the plants are at three leaved stage


  • 60cm × 60cm without staking
  • 50cm × 30cm with staking


Transplanting is done after the seedlings have reached about 15-20cm tall. This is about 25-30days. The plants should have attained up to 4-5 leaves stage before transplanting to the field. Planting in the field is 45-60cm between rows and 30-45cm between plants. Transplanting should done in the evening or during cool weather together with the ‘ball of earth’ to ensure survival of the seedlings.

Cultural Practices

  1. Weeding
  2. Watering (this should be done immediately after transplanting morning and evening)
  3. Fertilizer application: NPK 15:15:15 and organic manure are necessary
  4. Staking: this is to enable plants stand erect and prevent lodging. It also allows for good fruiting and keep fruit from disease attack arising from contact with soil.

Harvesting, Processing and Storage

Tomato matures between 2-4 months after planting (from transplanting). Harvesting is done by hand picking and it starts as from two months. For a short period, tomato can be stored in a refrigerator or spread on the floor in an airy room. For a long term storage, tomatoes are turned into paste and canned
