Every June, as the monsoon clouds gather over central Kerala, patches of the state's rubber-growing landscape turn bright red — not because of flowers, but because thousands of rambutan trees burst into fruit, their hairy crimson shells hanging in thick clusters from branches that, until a few years ago, would have yielded latex, PTI reported.
From latex to rambutan
For decades, rubber shaped the economy of Kerala's midland districts and other regions where the crop flourished, according to PTI. Falling prices, labour shortages and changing weather have left many small farmers searching for another source of income, and increasingly they believe they have found one. Once considered an exotic fruit seen only in home gardens, rambutan has quietly grown into one of Kerala's fastest-expanding commercial fruit crops. The change is most visible in the rubber-growing districts of Pathanamthitta, Kottayam, Ernakulam, Thrissur, Wayanad and Idukki, where young farmers are leasing land and planting rambutan orchards, PTI reported.
Area, output and revenue
According to the Rambutan Mangosteen Farmers' Organisation, the crop now covers nearly 25,000 acres across Kerala, producing around one lakh tonne this season and generating an estimated Rs 1,000 crore in revenue. The farmers' body said the industry's future depends on much more than cultivation. Farmers want the government to help them:
- build markets beyond south India;
- strengthen cold-chain logistics;
- promote Kerala rambutan across the country and abroad;
- encourage value-added products;
- support Farmer Producer Organisations; and
- counter misinformation that surfaces on social media during every harvest season.
The economics: rubber versus rambutan
M C Saju, president of the Rambutan Mangosteen Farmers' Organisation at Thirumarady near Koothattukulam, said rambutan represents an opportunity that Kerala's farmers cannot afford to ignore. He has grown rambutan in two different ways — one hectare with a spacing of 20 by 20, which he described as intensive farming, and another hectare planted with a spacing of 40 by 40. "It can be cultivated in both ways," he said.
The crop starts yielding from the third year and continues producing for decades. Saju said:
Production starts in the third year. If a tree produces about 30 kg in the third year, it will produce about 50 kg in the fourth year and about 70 kg in the fifth year. That is how its production increases. As the years go by, the yield keeps increasing and can reach up to 300 kg per tree.
| Year after planting | Yield per tree |
|---|---|
| 3rd year | 30 kg |
| 4th year | 50 kg |
| 5th year | 70 kg |
| Later years | up to 300 kg |
"If the price is even ₹100 per kg, a yield of 300 kg means an annual income of ₹30,000 from a single tree. That is the special feature of this crop," Saju said. He believes rambutan has advantages that many traditional crops no longer enjoy. "Whatever crop we cultivate on one hectare, the maximum earning capacity is usually around Rs 2.5 lakh to Rs 3 lakh. Rubber does not reach that level even if the price goes up to ₹300," he said.
| Metric | Rambutan | Rubber |
|---|---|---|
| Maximum earning per hectare | Around Rs 2.5 lakh to Rs 3 lakh (Saju); ₹14 lakh for one Ernakulam farmer | Does not reach Rs 2.5 lakh to Rs 3 lakh even at ₹300 |
| Labour need | Much less labour once orchard is established | Acute shortage of tappers; fewer tapping days because of changing weather |
Farmer returns and labour advantage
Another farmer from Ernakulam district said rambutan had transformed the economics of his farm. "This season I got ₹14 lakh from one hectare of rambutan. My total expenditure was only about Rs 60,000. This is the fourth year since I started getting yield," he said. Farmers say the fruit requires comparatively less labour than rubber, PTI reported. While rubber cultivation has become difficult because of an acute shortage of tappers and fewer tapping days caused by changing weather, rambutan demands much less labour once the orchard is established.
Post-harvest bottleneck and market potential
Farmers say the biggest challenge comes after harvest. Rambutan is a non-climacteric fruit, meaning it ripens only on the tree and has a short shelf life after harvest. Without refrigerated transport, cold storage and modern packing facilities, sending the fruit to distant markets becomes difficult, PTI reported. Saju believes the market potential is far greater than what Kerala is currently tapping.
