Is watermelon farming profitable?

Watermelon farming is very profitable, not capital intensive yet very rewarding. Here is a little calculation to back our claims up.

You can start your farm (say one hectare) with #100,000.
Here is what you need

  • Land (One hectare)
  • Seeds
  • Fertilizers
  • Pesticides
  • Running cash

One hectare of land using a planting distance of 1.2 meters, can contain about 5500 to 6800 plants of watermelon.

Note that one plant of watermelon can produce one to three balls of watermelon, this means that;

From one hectare of land, which bears over 6000 plants you can expect no less than 7000 balls of watermelon at least.

Remember you can have more if you manage your farm optimally.

Let’s assume you had a bad yield, only 6000 balls were harvested.

A ball of watermelon goes from #300 to #500 in the market depending on the size.
6000×300 = #1,800,000.

That’s  One million eight hundred thousand naira on a One hundred thousand naira investment.

That’s how profitable watermelon farming is, you can imagine growing bigger farm.

  • The soil topography should be flat and not sloppy

1.The soil should be Sandy Loam: The best soil for watermelon planting is sandy loamy soil, this is because sandy loamy soil contains the following.
2. Low water-holding capacity: Sandy-loamy soils contain moderate water holding capacity, this is because it allows for the movement of water in and out of the soil and therefore does not encourage waterlogging.
3. A good amount of organic matter: Sandy-loamy soil contains a good amount of organic matter; this is needed by watermelon for nourishment.
4.Rich organic minerals: Sandy-loamy soil is rich in organic minerals.
5. Lack of toxic chemical substances: Due to the presence of organic matter in the soil, sandy loam soils have very low or no toxic chemical substances.

  • Ensure that the soil is well-drained and is situated in a place where it gets access to direct sunlight.
  • The pH of the soil should be slightly acidic or close to neutral, watermelon enjoys soil with a pH range of 5.8 to7.2.
  • Watermelon is sensitive to salinity; therefore, the salinity (salt content of the soil) of the soil should be kept moderate for optimal production.
    Watermelon grows best in non-saline soils.
  • If you want to grow watermelon during the colder times, you must have to grow the plant indoors before exposing them to the outdoor Or you grow short-season varieties

Kindly note the following temperature requirements for watermelon farming.

The optimum growth temperature at night is 18°C -20°C, during the day is 24°C -30°C and for ripening, you have 15°C -25°C.

Step 2: Prepare the Land for watermelon cultivation

Preparation of land for watermelon cultivation involves segments of activities aimed at getting the land ready for planting.

  • Cut down already existing trees, grasses, shrubs, remove big stones, and other plant debris.
  • This will expose the land to the sun for proper aeration
  • Assemble the trees, grasses and shrubs that you have cut, burn them and allow the ash to dissolve into the soil, they serve as manure to the plant.
  • In a situation where you can’t burn them, bundle them and take them out of the land.
  • Till the soil for aeration, you can use conservative tillage, this will assist in retaining the soil nutrient at the top layers of the soil
  • You can as well plough the land especially if the soil is of clay content, this will loosen the soil for root penetration.
  • Treat the soil with chemicals to eliminate pathogens and organisms capable of causing harm to your plants
  • Detoxicate the land: Watermelon is known to be sensitive to manganese toxicity,  watermelons Seedling react to manganese toxicity with stunted growth and yellowish, crinkled leaves.
