Ideal crops for greenhouse farming.

Tomatoes.

Tomato is by far the main crop that can be grown in a greenhouse. It accounts for over 80% of all crops grown in greenhouses by small holder farmers. Once planted, first harvest is expected after 75 to 90 days and will continue for the next 6 months on good management.

Capsicums.

The main varieties are the coloured ones which fetch very good incomes. Yellow, red and orange capsicums are the most common and account for about 10% of small holder greenhouse farmers.

Cucumbers

These are grown for the specialty market.

Herbs

This includes Asian line of specialty crops such as basil, duthi and karella. 

Cut flowers.

Mainly grown for export market, they include roses, carnations etc. This is done by large scale farmers in Naivasha, Nakuru, Timau and Kajiado.

Greenhouse types

Steel Greenhouses

These are made of galvanized or non galvanized steel. The greenhouse maybe vented or tunnel type depending on the area. All Grekkon greenhouses are raised high to allow for proper crop ventilation.

Wooden greenhouses.

They are constructed using poles and other locally available materials.

Ventilation

The greenhouse has to be well ventilated to prevent suffocation of the crops. Ventilation also ensures there is no buildup of pests and diseases. This is done by erecting side curtains or roll up which is opened during the day when it’s hot and closed in the evening. It is made in such a way that there is a net on the inside to allow air in while at the same time preventing insect pests from getting inside.

  • Provide material transportation to site
  • Provide seedlings and other inputs such as fertilizers, pesticides and other chemicals.

Preparations before transplanting:

  • Seed Sowing. Tomato seeds are first sown in a nursery before transplanting them in the greenhouse. The best way to sow seeds is on seedling trays using soilless media such as coco peat. Seedling trays and coco peat are the most preferred method because they guarantee 100% germination rate compared to sowing in the soil. Male sure the coco peat is well treated before use. The germination should preferably be covered under a shade net.
  • Land preparation: Plough the land to a fine tilth then prepare the beds measuring 90cm with a path of 0.4m. Raise the beds 15cm high to allow for easier drainage incase of excess water. Raised beds also help with good root penetration. Prepare a maximum of 6 beds for a greenhouse with 8m width to avoid over crowding.
  • Add well decomposed manure on the beds then mix with a rake, removing all the big stones and sharp objects that may injure the roots

Transplanting greenhouse tomato seedlings

  • After 28 days, the seedlings are ready for transplanting. Open your drip lines 2 hours before transplanting to add moisture onto the soil.
  • Add High phosphorous basal fertilizer at a rate of 10gms per plant.
  • Transplant at a spacing of 40cm from 1 row to the other and 40-45cm from one plant to the other. 8m x 15m greenhouse can accommodate 500-600 plants while 8m x 30m greenhouse can accommodate 1,000-1,200 plants depending on the spacing selected. 
  • Consult your agronomist for a detailed crop management programme.
