About this variety
Konkan Prolific is a jackfruit cultivar name that appears in published research and is linked by name to the Konkan coast of Maharashtra. Its release year, fruit shape and size, flesh traits and yield have not been verified, so none is stated here. Claims of 70 fruits a tree and 25 kg a fruit are not supported by any source we could reach. For scale, TNAU gives an average of 12 kg for the large-fruited Palur-1.
Should you pick this variety?
Choose Konkan Prolific only if you farm on the Konkan coast of Maharashtra or Goa and can buy grafts from a nursery that names the source of its graft wood. Do not choose it for a promised yield or fruit size: we found no verified figure for either. Choose Palur-1 instead if you want figures you can plan on (TNAU: about 80 fruits, 900 kg a tree, 12 kg a fruit, and an off-season crop in November–December), though that variety was released for Tamil Nadu.
Sowing & cultivation
- Sowing timePlant grafts in June–December (TNAU). Cleft grafting for nursery plants is done in July–August on 4-month-old seedling rootstock.
- Spacing8 × 8 m (TNAU), in pits 1 m on each side. Assam's 2021 package of practices gives 10–12 m for its local and Singapore types.
- Sowing methodPlant a graft, not a seedling. TNAU fills each pit with topsoil mixed with 10 kg FYM and 1 kg neem cake. It prefers soil pH around 5.5 at planting; if the soil is more alkaline, TNAU treats the pit with 1% aluminium sulphate.
- IrrigationWater once a week until the plant is established. After that water only when needed (TNAU).
- FertilizerTNAU gives per tree, in two splits (May–June and September–October): a 1-year-old tree 10 kg FYM, 150 g N, 80 g P, 100 g K, with the same amount added each year. From the 6th year: 50 kg FYM, 750 g N, 400 g P, 500 g K.
- HarvestingTNAU says grafts start yielding in the 5th year (seedling trees in the 8th), and harvest runs March–July. TNAU puts the crop at 30–40 t/ha.
Soil & climate
Soil
- Suitable soil
- Deep, well-drained soil (TNAU). Rich, deep alluvial soil does best (Assam package).
- pH
- 5.5
Climate
- Climate
- The crop does well on the plains and up to 1,200 m elevation (TNAU).
Advantages & considerations
Why farmers may choose it
- Linked by name to the Konkan coast of Maharashtra, so a Konkan nursery is the natural place to ask about plants.
- Planted as a graft, which TNAU says starts yielding in the 5th year, against the 8th year for a seedling tree.
Things to consider
- No verified yield, fruit weight, release year or flesh trait, so test it before planting a large block.
- Check how it does in your rainfall and soil.

A yield claim to ignore, and what to do instead
Konkan Prolific is often described as a very heavy bearer with fruit up to 25 kg. The sources we reached do not say that. A 25 kg fruit is also far above the 12 kg average TNAU gives for the large-fruited Palur-1.
What we can say is only that the name is used for a jackfruit cultivar linked to the Konkan coast. Its release year and traits have not been verified, so we do not state them. Ask the nursery in writing where its graft wood came from.
So plan on your own numbers. Tag five trees in the fifth year, count the fruits and weigh a sample of ten. After two seasons you will know your yield. Buy more plants only then.
Where the planting material comes from
This variety is a grafted plant: the variety on top, joined onto a rootstock below. Seed out of its fruit will not come up as this variety, so it cannot be kept as seed. Buy grafted plants from a registered nursery or a government farm, so the plant is true to the variety and free of disease.

| Variety | Best for | Starts bearing | Yield | States |
|---|---|---|---|---|
| Gumless Jack | A low-latex jackfruit for farmers who cut and pack the bulbs and want a cleaner job, planted on trust in the trait until a trial says more | Grafted tree. NIF: the first graft (1988) began to yield about three years later. | No published trial yield. NIF reports that the first grafted tree gave 10 fruits in its second bearing year. | Karnataka |
| Konkan Prolificthis page | A jackfruit named for the Konkan coast, best tried on a small block first because we found no verified yield, fruit or release data | Grafted tree. No bearing month or age is given for this variety. | No verified per-tree or per-hectare figure found. | Maharashtra, Goa |
| Palur-1 (PLR-1) | A documented, high-yielding jackfruit with a second crop in November–December, chosen for steady income from one tree | Regular crop April–June and an off-season crop November–December (TNAU). TNAU says jack grafts start yielding in the 5th year. | About 80 fruits, around 900 kg a tree a year; average fruit 12 kg (TNAU) | Tamil Nadu |
| Rudrakshi | A small-fruited local jackfruit for home orchards and local sale, planted on reputation rather than on a trial record | Grafted tree. TNAU says jack grafts start yielding in the 5th year; Assam's package says 6 to 8 years for its types. | No trial yield found. Assam's package gives 200–500 fruits a tree a year for its local and Singapore types in general. | Karnataka |
| Siddu Jack | A coppery-red, high-TSS jackfruit for direct sale of colourful bulbs, planted for colour and sweetness, with a yield still to be proven by trial | Grafted tree. Source tree about 35 years old. IIHR gives no bearing age for grafts. | IIHR estimate: about 450 fruits, 1,098 kg a tree (fruit about 2.44 kg). It is an estimate from the source tree, not a multi-location trial. | Karnataka |
| Singapore Jack (NS-1) | The early-bearing choice for farmers who cannot wait five years, planted for a first crop in about three | Bears about 3 years after planting (KAU); extremely precocious. | 250 fruits a plant a year (KAU); no kg-per-tree figure published | Kerala, Karnataka, Tamil Nadu, Maharashtra, West Bengal |

Frequently asked questions
How big is a Konkan Prolific fruit?
We found no verified fruit weight or shape. A claim that fruit reaches 25 kg is not supported by any source we reached. For comparison, TNAU gives an average of 12 kg for Palur-1, a large-fruited variety.
What is the yield of Konkan Prolific?
We cannot give a firm figure, because we found no verified per-tree or per-hectare yield for this variety. For jackfruit in general TNAU gives 30–40 t/ha. Treat any other number you hear with care and plan on your own harvest records.
How do I check that a Konkan Prolific plant is the right variety?
Ask the nursery in writing where the graft wood came from: the mother tree, and the farm or institute that holds it. Ask the grafting date too. If you can, visit the mother tree and look at its fruit. We found no verified description of this variety, so comparing your plants against the mother tree is the only check you have.
When should I plant Konkan Prolific, and at what spacing?
We found no variety-specific planting advice. For jackfruit in general, TNAU plants grafts in June–December at 8 × 8 m in 1 m pits, with 10 kg FYM and 1 kg neem cake per pit. On the Konkan coast the monsoon months suit planting. Ask a government or university nursery for current local advice.
