As summer sets in, the markets of Madhubani overflow with watermelons — but shoppers almost always spot two distinct types side by side: a round, deep-coloured black watermelon and a striped one known as the Namdhari. What is curious is that both demand roughly the same plot of land, the same farming effort and about 6 months of growing time. And yet the black variety sells for ₹25-30 more per 5 kg than the Namdhari. Why does an identical farming process end in such different price tags? Digging into that question threw up an interesting answer.
Why watermelon matters in summer
Watermelon is among the most eaten fruits of the hot season. It is considered good for health because it is made up of nearly 70% water and is not overly sweet, which is exactly why people reach for it during heatwaves. So when two melons grown in the very same field carry different prices, a buyer's surprise is only natural.
The price gap comes from demand, not the farm
Speaking to farmers made one thing clear: the difference is driven not by the cost of cultivation but by market demand. The black watermelon is wanted more, and that is why it sells for roughly ₹25-30 more per 5 kg than the Namdhari.
In a conversation with TrendKia, farmer Umesh Chorbar explained that both varieties taste good, but people carry a firm belief that the black watermelon is sweeter than the Namdhari and that its flesh is redder on the inside. This perception keeps demand for the black melon high, and because demand stays strong, its price always sits ₹25-30 above the Namdhari for every 5 kg.
What the rates look like right now
According to Umesh, the Namdhari watermelon is currently selling at between ₹90 and ₹100 per 5 kg, while the black variety climbs to ₹125 to ₹130 per 5 kg. This ₹25-30 gap is not a one-off for this year — it shows up almost every season.
Equal at wholesale, different at retail
The most striking detail the farmers shared is that when they sell straight from the field to wholesale buyers, both types fetch nearly the same price. The difference appears later — it is these wholesale buyers who then sell the black watermelon dearer in the open market. Ordinary shoppers rarely notice this fine print while buying, but the next time you ask a vendor why the black one costs more, this is the very reason you will be told.
How long does a watermelon last at home
If you have just brought a watermelon home, it is worth knowing that, kept whole and uncut, it stays good for 5 to 6 days at room temperature. Stored in a refrigerator, it can remain fresh for anywhere from a week to 10 days.
