About this variety
Arka Muthu is a dwarf, short-internode watermelon from ICAR-IIHR, Bengaluru, bred so the vine stays compact and can be planted close. The fruit is small (about 2.5–3 kg), round and sweet — a convenient single-serve size — and the short vine suits raised-bed drip-and-mulch systems, small plots and even protected cultivation. It matures early at about 80–90 days, and its yield per acre comes from planting density rather than large fruit.
Should you pick this variety?
Choose Arka Muthu if you have a small plot, raised beds with drip and mulch, or protected cultivation, and a retail market that likes small, sweet, single-serve melons of about 2.5–3 kg. It is a dwarf, short-internode type bred for close planting, and it is early, at about 80–90 days. Yield is 35–45 t/ha, but it comes from planting density, not from big fruit. The catches: it is not for a market that wants a large melon, and its disease resistance is moderate. Choose Sugar Baby for 3–5 kg fruit on open land at lower cost. Choose Kiran if your buyer wants big 10–12 kg melons.
Sowing & cultivation
Advantages & considerations
Why farmers may choose it
- Dwarf, short vine — can be planted close, so yield per acre comes from density
- Small, sweet, single-serve fruit with a growing retail market
- Fits raised-bed drip-and-mulch systems and small or protected plots
- Early at about 80–90 days
Things to consider
- Small fruit — not the choice where the market wants a large melon
- Disease resistance is moderate; check local Fusarium wilt pressure before planting on repeat cucurbit land

Yield from density: cost the seed, drip and labour first
Arka Muthu's 35–45 t/ha comes from planting many small plants close together, not from big fruit. More plants means more seed, more drip points and more hands for training and picking.
Before you plant, put one sheet together: seed per hectare at the spacing your area uses, drip and mulch cost, labour per picking, and the price per kilo you must get for 2.5–3 kg fruit. Ask your horticulture office or the seed seller for the local spacing.
Compare the net with Sugar Baby on open land. If a small retail buyer pays enough more per kilo, Arka Muthu wins. If not, the cheaper variety does.
Can you keep your own planting material?
This is an open-pollinated variety, so seed from a healthy crop of your own can be sown again. Keep seed only from disease-free plants, dry it properly, store it cool and dry, and bring in fresh certified seed every three to four years so the variety does not drift.

Frequently asked questions
Will customers buy a 2.5–3 kg watermelon?
Single-serve melons have a growing retail market. That means shops, home delivery and small families more than the mandi trader who weighs by the truckload. Show a few fruits to your retail buyers and ask the price per kilo and per fruit before you plant a whole field.
Why does Arka Muthu's yield come from planting density?
The fruit is small (2.5–3 kg), so each plant gives less weight than a big-melon variety. The short vine lets you put more plants in the same land. The 35–45 t/ha on the card is for high density. No spacing figure is published, so ask your horticulture office or the seed seller for the spacing used in your area.
Does Arka Muthu suit protected cultivation?
Yes, the short vine suits small plots and even protected cultivation, as well as raised-bed drip-and-mulch systems. Its small size is the reason. Check the cost of the structure against the price per kilo you can get for small fruit before you commit.
Can I save Arka Muthu seed?
Yes. It is an open-pollinated variety, so seed from your own fruit gives plants like the parent. Save from healthy, typical plants with the small, sweet, round fruit, and not from a diseased patch.
Does Arka Muthu need a wilt check before planting?
Yes. Its disease resistance is moderate, so check local Fusarium wilt pressure before planting on repeat cucurbit land. If the field had watermelon, melon or cucumber recently, choose another plot or rotate first.
