About this variety
Narendra Jamun-6 is a selection from Narendra Dev University of Agriculture and Technology, Faizabad, Uttar Pradesh. An account of Indian jamun says the university located a selection with desirable traits and named it Narendra Jamun 6. We found no measured fruit weight, pulp share, TSS or yield per tree for it, and no sodic-soil result. It is not one of the four cultivars in the Godhra, Karnal and Punjab trials. So we cannot rank it against Goma Priyanka, Konkan Bahadoli or the CISH selections. What we can give is a way to check a plant before you buy.
Should you pick this variety?
Choose Narendra Jamun-6 only if you farm in Uttar Pradesh and have seen a fruiting tree, at the university or a nearby orchard, and liked the fruit size, stone and taste. No trial figures exist to back it. If you want a documented crop in the same state, CISH J-37 from Lucknow has trial data (Karnal, Godhra), and Goma Priyanka has the highest yield in the Godhra trial. Ask for grafted plants, not seedlings.
Sowing & cultivation
- Sowing timeSpring (February–March) or monsoon (July–August). The monsoon is better (TNAU).
- Spacing10 × 10 m (TNAU). The Godhra trial planted these cultivars at 5 × 5 m.
- Sowing methodPlant a budded or grafted plant, not seedling jamun, in a 1 × 1 × 1 m pit filled with 75% top soil and 25% well-rotted farmyard manure or compost (TNAU).
- IrrigationYoung trees need 8 to 10 irrigations a year. A mature tree needs about half that, given in May and June while the fruit ripens. In autumn and winter irrigate only when the soil is dry (TNAU).
- HarvestingHarvest in June–July by hand. Ripe fruit cannot stay on the tree, so pick as it ripens (TNAU).
Soil & climate
Soil
- Suitable soil
- Deep, well-drained loam gives the best yield. The tree tolerates salinity and waterlogging. Very heavy or very light sandy soils are uneconomical (TNAU).
Climate
- Climate
- Tropical and subtropical, up to 1,300 m in the lower Himalayas. Dry weather is needed at flowering and fruit set, and early rain helps ripening (TNAU).
Advantages & considerations
Why farmers may choose it
- A selection from an Uttar Pradesh university, made for UP farmers
- Named and traceable to Narendra Dev University, so you can ask the source for a fruiting mother tree
Things to consider
- No measured fruit weight, pulp share, TSS or yield is published for it, unlike Goma Priyanka and the CISH selections.
- One account says it is usually multiplied by seed. TNAU advises against seedling jamun because it bears late (8–10 years against 6–7 for grafted).

Ask how the plant was made before you pay
One account says Narendra Jamun 6 is usually multiplied by seed. That matters. TNAU says seed is not advisable for jamun, because it brings late bearing: 8–10 years for a seedling, against 6–7 for a grafted or budded tree.
A seedling can also differ from its mother tree, so you may not get the fruit you saw. Ask the nursery three things: was this plant budded or grafted, from which named mother tree, and can you see that tree in fruit.
TNAU's method is budding on one-year-old seedling stock, 10–14 mm thick, in July–August in low-rain areas or May–June where rains come early and heavy. Write the variety, the mother tree and the date on the bill.
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.

| Goma Priyanka | A productive, smaller jamun tree for closer planting on ordinary soil | Grafted plant: first fruit in about 4–7 years; ICAR's 50–70 kg a tree is from the 10th year | 50–70 kg/tree from the 10th year (ICAR) | Gujarat, Maharashtra |
| Konkan Bahadoli | A jamun that grafts with fewer losses, for nurseries and first-time farmers | Grafted plant: first fruit in about 4–7 years (guides differ; TNAU says 6–7) | No kg-per-tree figure published; below Goma Priyanka and CISH J-37 on yield at Godhra | Maharashtra, Karnataka |

Frequently asked questions
Where was Narendra Jamun-6 selected?
At Narendra Dev University of Agriculture and Technology, Faizabad, Uttar Pradesh. An account of Indian jamun says the university found a selection with desirable traits and named it Narendra Jamun 6. We found no release year or notification, so ask the university for its own record.
Is there yield or fruit-quality data for Narendra Jamun-6?
Not in anything we could reach. No paper we read gives its fruit weight, pulp share, TSS or kg per tree. For comparison, Goma Priyanka has ICAR's 50–70 kg a tree from the 10th year and 85–90% pulp. Without numbers, judge Narendra Jamun-6 on a fruiting tree.
Can I grow Narendra Jamun-6 from seed?
You can, but TNAU advises against it. A seedling jamun bears in 8–10 years, a grafted or budded one in 6–7, and seedlings can differ from the mother tree. Buy a budded or grafted plant, with the mother tree named on the bill.
How does Narendra Jamun-6 compare with CISH J-37, which is also from Uttar Pradesh?
J-37 has published results and Narendra Jamun-6 does not. J-37 was the only cultivar rated tolerant of sodic soil at Karnal (0.76) and came second in yield at Godhra. For Narendra Jamun-6 there is only the university's name behind it. If you want a documented pick, J-37 is it. If you want the local selection, plant a few trees first.
