Bael (Aegle marmelos) is one of the few fruit trees that gives a commercial crop without irrigation in dry, hot, semi-arid land, and ICAR-CIAH's Godhra station reports economic yield with rainfall as low as 400 mm. It is a slow orchard crop: grafted trees fruit from year 2 but give an economic crop only after about year 5, and full yield comes near year 10.

The published returns come from one research station in Gujarat, and bael is thinly traded, so the buyer for fresh fruit, pulp or powder must be found before planting.

Where it grows in India

  • Range: ICAR-CIAH describes bael as growing throughout India, in sub-tropical, tropical, arid and semi-arid regions. Variety work is based at Faizabad and Lucknow (Uttar Pradesh), Godhra (Gujarat), Bikaner (Rajasthan) and, for trials, the Kymore Plateau and Satpura Hills zone of Madhya Pradesh.
  • Dryland limits: the Godhra trial site had about 790 mm mean annual rain (range 300 to 910 mm), summer maximum up to 42 degrees C, and clay to clay loam soil of pH 7.9 only 0.7 to 0.9 m deep over limestone. Bael still bore well there without irrigation.
  • Soil: a farming guide reports growth in soils of pH 5.0 to 10.0 and salinity tolerance up to about 9 dS/m. Waterlogging is the thing to avoid.

Yields are from different sites and tree ages, so they cannot be ranked against each other. ICAR-CIAH recommends growing several of its varieties together so that fruit is available from January to July. Choose the variety tested nearest your district and ask your KVK.

Planting material and spacing

  • Propagation: one-year-old seedling rootstocks are budded. In-situ patch budding in May and June before the monsoon, with a one-month-old scion, gives over 95% success; softwood grafting over 85%. Buy budded plants of a named variety; seedling trees fruit later and vary.
  • Pits: 1 m x 1 m x 1 m, filled with a 50:50 mix of farmyard manure and topsoil, plus 125 g single superphosphate and 150 g neem cake. Drenching with chlorpyriphos at 1 to 2 ml per litre is advised against termites in the early years (follow the label and your KVK).
  • Season: plant just after the first rain so the plant establishes in the monsoon.
  • Spacing and density: 5 m x 5 m gives 400 trees per hectare (about 160 per acre); 6 m x 6 m about 280 per hectare (113 per acre); 7 m x 7 m about 204 per hectare (82 per acre).

Nutrition, irrigation and canopy

  • Dose per tree: the ICAR-CIAH production guide gives 10 kg farmyard manure, 50 g nitrogen, 25 g phosphorus and 50 g potassium per plant per year in two splits, rising in the same proportion up to age 10. Apply the manure, half the N and K and all the P after the first rain, and the rest in the last week of August. The Goma Yashi trial used 10 kg FYM, 25 g N, 50 g P and 50 g K at age 1, increased every year, plus zinc sulphate (100 g per tree from year 6).
  • Per hectare: at 400 trees per hectare, the year-1 dose is about 4 tonnes FYM, 20 kg N, 10 kg P and 20 kg K per hectare, and it scales up with tree age. Micronutrients are applied after the third year.
  • Water: the Goma Yashi trial plants were never irrigated; they relied on a 20 cm paddy-straw mulch in the basin, renewed yearly. Where water is available, a farming guide gives 8 to 10 irrigations a year for young plants and 4 to 5 during fruit development; see drip irrigation.
  • Canopy: train to a modified leader system in the first 3 to 4 years, then prune about 25% of annual growth in alternate years while the tree is leafless (in the trial, in May).

Pests, diseases and disorders

  • Pests: lemon butterfly caterpillars on foliage are the main loss. Citrus leaf miner, spiralling whitefly and scale are minor or patchy. Bacillus thuringiensis and yellow sticky traps are listed alongside chemical options.
  • Diseases: bael has no serious disease, but canker (Xanthomonas), shot hole, powdery mildew, gummosis, stalk-end rot and post-harvest fruit rots occur. Avoid bruising fruit at picking; hot-water dipping at 52 degrees C is described for shell soft rot.
  • Fruit drop and sun scald: fruit drop is reduced by mulching, balanced nutrients, 0.1% borax or NAA at pea stage. In hot semi-arid land sun scald browns the exposed shell; canopy cover, mulch and covering fruit with foam net help.
  • Follow the label and your KVK for any spray. See pests.

Harvest and yield

  • Time to crop: in the Goma Yashi trial fruit set began in year 2, but economic yield came after year 5.
  • Picking: pick fruit one by one with 2 to 3 cm of stalk to avoid rot. Varieties mature from about April to early May at Godhra; farming guides give a February to May window for different regions.
  • Yield per tree, Goma Yashi rainfed, 5 m x 5 m: 0.57 kg in year 2 rising to 59.27 kg in year 10, which is about 237 quintals per hectare (about 96 quintals per acre).
  • Newer Thar varieties: 91.5 to 115.75 kg per tree in years 9 to 12 at the research station; mature farm yields may differ.
💡 Tip: Ask your buyer in writing for a rate per kg for the variety you plan to plant. The research returns below were worked out at two assumed rates, not at a market price.

Cost and returns

  • Station result: for Goma Yashi at 5 m x 5 m, rainfed, in year 10, ICAR-CIAH computed net profit of ₹1,87,080 per hectare at an assumed ₹10 per kg and ₹4,24,160 per hectare at ₹20 per kg, after costs. That is roughly ₹76,000 to ₹1.72 lakh per acre. These are single-site, year-10 figures; earlier years earn far less (gross at ₹10 per kg was only ₹2,280 per hectare in year 2).
  • Arithmetic to repeat with your own rate: trees per acre x kg per tree x rate. For 160 trees at 59 kg and ₹10 per kg the gross is about ₹94,000 per acre; at ₹20 about ₹1.9 lakh.
  • Running costs in dryland are low (manure, mulch, pruning, picking), but cash comes late; budget for 5 to 6 years with little income. Ask your district horticulture office for the current cost norm for loans (KCC).

Market and selling

  • Fresh fruit sells in local markets; processors make sherbet, squash, candy, murabba, powder and Ayurvedic preparations. Goma Yashi is described as suitable for sherbet, squash, candy and murabba; high-fibre types such as Thar Prakriti for powder. Check mandi bhav; bael may not be listed everywhere.
  • Demand is local and seasonal, and fruit loses quality in 1 to 3 weeks, so processing or a nearby buyer matters. Groups can sell through an FPO.
  • Be wary of plant sellers who promise fixed buy-back. For orchard support, see the subsidy finder; ask the district horticulture office for the current per-hectare planting rate.
