Gross margin analysis for open field tomato cultivation in Kenya

Assumptions

  • This profit analysis assumes a constant selling price of KES 50 for a Kg of tomatoes throughout the harvesting period.
  • The costs of farm inputs and labor etc are assumed to be the prevailing costs in the most productive tomato-growing areas in Kenya like Mwea, Ngurumani, or Subukia.
  • The tomato field season lasts 16 weeks

Detailed Revenue Analysis

To get the projected revenues, get the product of the average yields and the assumed selling price per kilogram above.

Total yields and revenue

In Kenya, you can harvest 35,000 kg of tomato fruits per acre. In this analysis, we assume that 85% or 30,000 kg of the Kilele F1 variety will be marketable. You can therefore earn KES 1.5 million from an acre of tomato in Kenya under proper crop care. It is after selling each kg at KES 50 per kg. If you are a small-scale farmer, in a quarter acre of land, you would harvest 7500 kgs. After selling them at KES 50 per kg you would earn KES 375,000. The factors that may limit you from getting these are differences in variety, spacing, soil characteristics, water availability, etc.

Detailed Cost analysis

Growing tomatoes in one acre will cost you KES 190,635. These will be used for land preparation to harvesting.  The detailed expenses for the vegetable crop are further detailed below: –

Best tomato seeds for open-field cultivation

There are various varieties of tomato variety seeds available in Kenya. You can go buy the open-pollinated or the hybrid (F1) types.  The table below is a summary of the most popular determinate tomato varieties that are suitable for open-field production.

This analysis uses the Kilele F1 seed variety. It is a good choice given it’s a hybrid with higher yields.  It is a determinate type suitable for dry and humid regions.  Kilele F1 matures in 75 days after transplanting and you can harvest 30,000-35,000 kg per acre. Besides the ripe fruits are Firm and elongated and have a shelf life of 21 days.

Soil Testing and water analysis

The ideal ecological conditions to get big tomato fruits are as shown below for soils and rainfall. Tomato crops grow at an altitude of 0-2000 meters above sea level with temperatures of 20-25°C during the day and 15-17°C at night.

  • Tomatoes require well-drained sandy, loam, or clay soils. A PH value of 6.0-7.5. Besides, the crop needs an adequate supply of nitrogen, phosphates, and potassium nutrients for optimal production.  To determine if your soil is fit for tomato production do a soil testing at a cost of KES 1500.
  • Tomato produces well under ample rainfall of 600 mm and above. You may need to irrigate them to improve yields. You will need clean portable water fit for consumption. To test this, you may conduct a cheap water testing service.

In addition to water and soil testing, you can carry out a pathological test to determine that your soil if free of any pests and diseases before planting.

How to establish a tomato nursery

You will need to establish tomato seedlings in a seed nursery or seed trays. You will need 50-75 g/acre of tomato seeds for your field. These will contain 10,000 seeds at a cost of KES of 2.70 per seed. You will incur additional costs for preparing the seedbed, pest control, and watering.

Alternatively, you can buy mature seedlings from a certified seed raiser. Most sell high-quality planting materials at an average cost of KES 3.00 for each.

Land Preparation & Transplanting

The land preparation costs include paying a lease to hire farming land, plowing, and harrowing to make fine tilth for vigorous seedling establishment. Other costs are for making planting holes or ditches. Besides, you will have to apply farmyard manure and planting fertilizer at this stage before transplanting.­­­­­

The recommended spacing for tomato crops is 75 by 40 cm in wet areas and 60cm by 100 cm in dryer areas. You will plant from 6,666 to 13,333 plants in an acre. The right space will give you short stocky plants with strong roots.

Best fertilizers for tomato plants

You are advised to carry out a soil test before establishing your fertilizer needs.

To prepare holes, apply 2-3 handfuls of manure in each. For an acre, you need 8 tons at a total cost of KES 16,000. You will then add 2 bottle tops of planting fertilizer like DAP, TSP, or MOP to provide potassium for root development. You will therefore need 100 kg per acre at a cost of KES 7,000.

To boost your tomato yields, you need to top-dress it twice with a nitrogenous organic or inorganic fertilizer like the CAN.  The first is done at 4 weeks after transplanting at 40kg/acre. The second split is done on the 8th week at a rate of 80kg/acre. Total topdressing will cost you KES 7,200.

Apply a foliar fertilizer during the flowering period to promote vegetative bloom. You will need 16 kg of this at a cost of KES 400 each.

Staking and Training

To get quality tomato fruits, you need to stake them to avoid any contact with the soil during the wet season.  The other alternative is to apply a clean mulch like hay straws.

To stake you need strong wooden stakes or bamboo sticks to act as poles. An acre needs a1000 stakes at a cost of KES 1 for each. You will need 20 plastic strips or strings to train the plant to stake.

Crop protection

Tomato crops are susceptible to many pests and diseases as listed below.

List of the common tomato pests and diseases in Kenya

You will spend KES 71, 435 to control tomatoes and pests and diseases in Kenya. This analysis uses a conservative method of good agriculture practices (GAPs). It proposes the use of bio-pesticides alongside the prudential use of chemical pesticides.

Bio-pesticides suggested for your use are pheromone traps like trianum, tutasan water traps, and pherodis Tuta. The others are the use of the Horriver yellow, Vidi Parva, and Savona. The recommended chemical pesticides to spray your tomatoes are amitraz, Buprofezin Azadirachtin Imadpcroprid, etc.

Additional methods to keep diseases and pests at bay are;

  • Plowing and harrowing before transplanting to kill pupae in the soil.
  • Carry out regular scouting/monitoring of pest population.
  • Use resistant tomato varieties and use certified disease-free seeds and seedlings.

Labor costs

Tomato is a labor-intensive crop to manage. You need KES 19,200 for labor only to grow tomatoes in an acre. It is equal to 64 man-days to manage crops from land preparation to post-harvest like sorting and grading. The workdays are for planting, watering, and topdressing. Others are for Spraying farm chemicals, transplanting, and staking them. All the anticipated costs are available in the GMA above.

When is the best time to harvest tomato fruits?

Tomato matures in 75 days on average for most varieties in Kenya. You can harvest the fruits at four maturity indices or stages based on market requirements and the distance of the market. These are.

Tomato Maturity IndexHarvesting stage
Mature-Green Stage:Up to 30% of the fruit surface has definite color break from green to yellow
Breaker/Turning Stage:Up to 30% of the fruit surface has a definite color break from green to yellow
Pink/Light Red Stage30 – 90% fruit surface has pink/red color.
Red/Ripe Stage:over 90% fruit surface has changed to red color.
Tomato harvesting maturity indices and stages.

The ideal harvesting time is early in the morning and fruits have low temperatures. Keep them in a cool, shaded, and ventilated area. You can wipe them to remove dirt. Sort them to remove damaged and diseased fruits. You will need to grade them into big, medium, and small size fruits. Pack your Tomatoes in clean and ventilated wooden and plastic crates for transport.

Marketing and Other costs
