J33 Jackfruit (Artocarpus heterophyllus ‘J33’)

A premium commercial jackfruit cultivar originating from Malaysia and extremely popular in Kerala, celebrated for producing large fruits with thick, firm, bright golden-yellow flakes (varikka) that deliver a crisp texture, low latex content, and an intensely rich, honey-sweet flavor profile.

Grafted trees adapt exceptionally well to container culture and home gardens, maintaining a manageable semi-dwarf structure with regular formative pruning and fruiting early within just 1 to 3 years compared to 7+ years for seed-grown jackfruit trees!

Description

J33 Jackfruit (Artocarpus heterophyllus ‘J33’) grows best in 6–8 hours of sunlight and thrives in warm, humid tropical climates. It is known for its yellow jackfruit bulbs with a sweet flavour and firm texture. Water regularly during the early growth stage and dry periods, keeping the soil moist but not waterlogged. It prefers deep, fertile, well-drained soil rich in organic matter. Choose a spacious planting location to accommodate the tree’s broad canopy and root system, and protect young plants from strong winds.

Recommended Planting Method for Best Results

For healthy growth and strong establishment, prepare a 2–3 ft deep pit. If available, place a layer of green leaves at the bottom. Mix 1.5 kg bone meal, 1 kg oil cake, 20 kg raw cow or goat dung, and 100 g urea with an equal quantity of soil, then fill the pit and cover it with soil.

Leave the pit for about one month, watering it daily so the mixture decomposes well. After one month, mix the contents again and add 100 g calcium or dolomite. Wait one more week, then plant the sapling.

If you need to plant immediately and cannot wait for the one-month decomposition period, do not add oil cake or calcium/dolomite; use only the soil, manure, bone meal, and urea mixture for planting.
