Here is the List of Basic Aspects and Techniques to Know Before You Start Watermelon Cultivation Business
Learn the Health Benefits of Watermelons
It is very important to have some understanding of the benefits of consuming watermelons before starting cultivation. Find below some of the benefits.
- Watermelon’s high levels of lycopene are very effective at protecting cells from damage and may help lower the risk of heart disease, according to a study at Purdue University.
- Watermelons are the perfect example of a food that can help you stay hydrated.
- The watermelon contains fibre, which encourages a healthy digestive tract and helps keep you regular.
- Watermelon is a natural diuretic which helps increase the flow of urine but does not strain the kidneys.
- Rich in potassium, watermelon is a great natural electrolyte and thus helps regulate the action of nerves and muscles in our body.
- Watermelon is a wonderful source of beta-carotene which is converted in the body to vitamin A.
- The vitamin C content in watermelon is astoundingly high. Vitamin C is great at improving our immune system by maintaining the redox integrity of cells and thereby protecting them from reactive oxygen species.
Understand the Best Varieties For Watermelon Cultivation
Watermelon varieties fall into three broad classes based on how the seeds were developed. These are open-pollinated, F1 hybrid, and triploid or seedless. Open-pollinated varieties are developed through several generations of selection. F1 hybrid seed will be as much as five to 10 times as costly as open-pollinated seed, and available F1 hybrid varieties will change from year to year. If you want to use your own seed next year, buy an open-pollinated heirloom variety.
Some of the popular Indian watermelon varieties are:

- Durgapura Kesar – A late maturing variety. This is green in colour with stripes; flesh yellow in colour and moderately sweet, seeds are large. Average fruit weight 4-5 kg.
Suitable Agro-Climatic Condition For Watermelon Cultivation
Watermelon seed germinates at soil temperatures of 68° to 95° F; however, germination below 70° is very slow. At a soil temperature of 77°, watermelon plants should emerge in about five days. Watermelons do not cope well with extreme heat or the humid, soggy conditions of our wet season/summer. Fungal diseases and bugs will wipe them out in no time.
If you live in a cooler climate, then summer is the time to grow watermelons. You do need at least three months of reliably hot, sunny weather to grow and ripen a watermelon. During that time, your average daily maximum temperature should be at least about 20-25°C or 70-80F. Warmer is even better.
Suitable Soils For Watermelon Cultivation
Amend soil with aged manure, seaweed, and/or compost before planting. Watermelons are heavy feeders. Watermelons prefer a soil pH between 6 and 6.8. Mulching with black plastic will serve multiple purposes: it will warm the soil, hinder weed growth and keep developing fruits clean.
In fertilization, make sure it delivers more nitrogen than phosphorus and potassium. However, after flowering begins, use a fertiliser with less nitrogen. Most recommended is liquid seaweed extract.
How to Do Watermelon Cultivation From Seed
Watermelons are grown from seed. Watermelon seed germinates easily and quickly, within a few days. Watermelon plants outgrow the seedling stage very quickly, and they don’t like transplanting. Watering is very important from planting until fruit begins to form. While melon plants are growing, blooming, and setting fruit, they need 1 to 2 inches of water per week.
Keep soil moist but not waterlogged. Water at the vine’s base in the morning, and try to avoid wetting the leaves and avoid overhead watering. Drip irrigation is also a good alternative. Reduce watering once fruits are growing. Dry weather produces the sweetest melon.
Watermelons grow male and female flowers on the same vine. The smaller male flowers appear first. The female flowers are much larger. Watermelon flowers are insect pollinated. Hand pollination is also possible.
Plant Protection System For Watermelon Cultivation
The biggest watermelon pests are the leaf-eating beetles (they damage the flowers, too) like spotted and striped cucumber beetles, pumpkin beetles with or without dots. The other main problem with growing watermelons is mildew, a fungus that makes the leaves look as if they were coated with white powder. The fungus thrives in damp, humid conditions. You must obtain precaution to overcome these problems.
Best Month for Watermelon Cultivation – Harvesting & Storage Techniques
Watermelons don’t sweeten after they are picked, so harvest time is important. Watermelons are hand-harvested at full maturity for best taste and texture. Indicators of watermelon fruit maturity include a yellow spot on the fruit surface in contact with soil or plastic mulch; a brown, dried tendril where the fruit stem is joined to the watermelon vine; and a dull surface on top of the fruit.
Cooling the watermelons after harvest to 45-50°F will remove field heat and improve shelf life and taste. Watermelons will retain good quality for approximately 21-28 days if stored at 85-90 per cent humidity and 47-55°F.
Watermelons are grown for the fresh market. Large-scale producers (more than 20 acres) generally use brokers who provide the marketing services to the producers. The average US farm price for watermelons in 2014 was $13.50 per hundredweight. The national seasonal average retail price for non-organic, red-fleshed, seeded type ranged between $0.31to $0.38 per pound and $0.46 to $0.55 per pound for red-fleshed seedless.
The field method of sales, whether by the acre or by the pound, is preferred by many growers because it is relatively simple. Basically, the grower finds a buyer willing to purchase the entire field. Often, the buyer does the harvesting. Watermelon cultivation is profitable even for small farm owners having 1 acre of land.
To sum up, the basic things to Consider in starting Watermelon Cultivation are the following;
- According to your agro-climatic condition, choose the right variety.
- Check the soil condition and PH balance
- Arrange the irrigation facility
- Start planting in the right time (season)
- Conduct some market research for fresh fruit selling
- You must have proper knowledge about fertilization, planting, pollination, plant protection and harvesting.
- Prepare a budget and make the financial resources accessible
- In the case of export, make a contract prior to the agents or companies.
Remember, watermelons take considerably long time to grow, around ninety days. So patience is the key to be successful in this business. If you are a beginner, it is advised to start watermelon cultivation on a smaller scale and then when profit starts coming in, scale up your business on a larger format.
