Horticulture tips on Andaman & Nicobar Island


  • Choose high yielding round fruited cultivars according to local market needs.
  • For fruit and shoot borer control, Integrated Pest Management approaches should have been used.
  • Bacterial wilt resistant brinjal types such as CARI brinjal-1, & 2, as well as various local private company kinds


  • Lime treatments at a rate of 100kg/acre prior to seedling transplanting
  • Grow only wilt-resistant types such as Arka Rashak Laxmi, Utkal Raja, Utkal Urbasi, and others.
  • Avoid transplanting seedlings on wet days.
  • Choose sandy soils for improved crop development and production.

Cole Crops:

  • Only tropical high-temperature resistant types such as white marvel, white short, and others should be grown.
  • Avoid transplanting seedlings during periods of heavy rain.
  • Bio fertilisers and bio-inoculants should be applied to seedlings.
  • Before transplanting, apply biofertilizers to the soil.
  • Micronutrients such as boron, zinc, calcium, and molybdenum should be used.
  • Excessive use of chemical fertilisers such as DAP and Urea should be avoided.
  • During the winter, drain surplus water from the field and grow on a raised bed.

French beans

  • French beans should always be grown on poles.
  • Yellow vein mosaic and aphids should be controlled as soon as possible to avoid crop loss

Root crops

  • For root crops, always use sandy loam loose soil.
  • Pusachetaki, a Japanese long radish cultivar, should be planted.
  • Improved biofortified sweet potato cultivars such as Bhu-sona and Bhu-Sakti, as well as CARI SP-1 and CARI SP-2, should be chosen.
  • Carrot varieties from Asia, such as Pusa Rudhira and others, should be grown.
  • The soil-borne disease will benefit from the use of neem manures and Trichoderma powder.


  • Plant leaf curling resistance variants such as VNR-Black, bullet mirch, Pusajwala, MDU-1, and others.
  • Control of viral illness is advised by spraying imdachlorophid 1ml/liter water and subsequently spraying 0.05 percent Dimethoate (Rogor), soil application of neem manure or carbofuran @1.5kg/ha.
  • Spray NAA at 50 ppm during the full bloom period to reduce excess flower drops.
  • Anthracnose in fruit is controlled by seed treatment with Thiram or Captan at a rate of 2gm/kg, as well as spraying with Benomyle at a rate of 0.1 per cent.

Cucurbit vegetables:

  • Due to the hot, humid conditions, cucurbits such as pumpkin, ridge guard, cucumber, and bitter gourd are extremely susceptible to downy mildew disease. During the early stages of infection, spray cupperoxichloride (Blitox) or Mancozeb to control the sickness.
  • Powdery mildew has been seen in numerous cucurbit vegetables, and it should be controlled by spraying Dinocap (karathane 0.03 per cent) and dusting with sulphur dust.
  • During Rabi season, leaf mosaic viruses in various cucurbits, such as bitter gourd, are commonly observed, resulting in insect vector control.
  • Anthracnose has also been recorded in various cucurbit vegetable fruits, and repeated spraying with mancozeb or Zeneb has been recommended (Dithane-Z-78)
  • Fruit fly and red pumpkin beetle are more significant pests that harm maximum’s fruits and leaves.


  • Follow fusarium wilt management measures in the field owing to erratic rain, and eliminate excess waterlogging.
  • The addition of TIBA 25ppm, MH 50ppm +GA 25ppm, boron, and calcium @20ppm will aid in fruiting and cracking.


  • Grow YMV resistant varieties and spray with Dimethoate (Rogor) every 10 days.
  • Powdery mildew has been observed on occasion and has been handled in accordance with prior crops.
  • Spotted bollworm-infected fruit is removed, and carbaryl or neem manures are applied to the soil.


  • Prepare to vermicompost from coconut trash such as leaves, flower sheaths, and so on.
  • In a coconut orchard, fallow clean cultivation is practised.
  • If necessary, watering should be followed by the construction of a basin in the coconut trees.
  • Mulching should be done with coconut leaves, husk, or other organic materials.


  • Clean cultivation and mulching of areca nut orchards should be done with areca nut residue.
  • To avoid root infections, use neem manure.


  • If you discover rhizome weevils in your planation, make sure the area has appropriate drainage.
  • Remove any damaged rhizomes from the field and dust with chlorpyrifos.


  • Infection of mango fruit fly seen in late March-April-May; these insects can be controlled by installing sex pheromones. Dimethoate 0.045 percent + molasses 0.1 percent spray
  • For one hour, soak mature unripe fruits in a 5% sodium chloride solution in water.
  • Shooty mould fungus grows in the shadow or inner region of middle Andaman; treat with a good fungicide twice before maturity.


  • Install a sex pheromone trap to keep fruit flies at bay.
  • To control fusarium wilt, apply Trichoderma powder to the root zone of guava.
  • Citrus fruits (oranges, limes, lemons, Pomaleo): After harvesting, provide correct nutrition and do not let the fruits mature on the trees.
  • Application of Trichoderma powder on a regular basis to reduce wilt and dieback in citrus crops.
  • Marigold
  • For commercial production, grow all-year marigold cultivars such as Bidhan Marigold-2 and other African marigold blooms.
