Banana

Climate and soil

The banana is cultivated between sea level and 1000 to 1200 m above mean sea level and favours tropical humid lowlands. The ideal temperature is 27 °C, RH-75-85%. The best soils are those with high fertility and a consistent supply of rainfall. The best soil for banana production is deep, rich loamy soil with a pH of 6–7.5.

Land Preparation
At least three or four thorough plowings should be performed on the ground. During the last ploughing, add around 10 tonnes of well-rotten FYM or compost and thoroughly mix it, or add 10-15 kg of FYM or compost per pit with a diameter of 60x60x60 cm.
Seed rate and spacing
A spacing of 1.5m x 1.5m can accommodate about 1800 plants per acre

Irrigation Management
Throughout their whole life cycle, banana plants need between 900 and 1200 mm of water, which may be provided by both rainfall and supplemental irrigation. In order to encourage better development and increase production, maintaining ideal moisture levels at all phases of growth is crucial, and providing appropriate drainage facilities to drain excess water from the root zone is equally vital. In general, it is advised to irrigate banana plants every three to four days during hot weather and every seven to eight days during cooler weather.
Weed management
Soon after planting, a pre-emergence treatment of atrazine or diuron at 1.5 to 2 kg/ha would maintain the ground weed-free for three to five months. Paraquat, Dalapon, 2,4-D, or glyphosate may be used post-emergence.
Insect pest management

Rhizome weevil: Cosmopolites sordidus      

  1. Choose a robust sucker and plant.
  2. To prevent an early infestation, avoid cultivating a normal crop in the same land.
  3. Ensure sterile farming.
  4. Rhizome trimming must be done.
  5. Grow types that are less prone.
  6. Cosmolure trap should be used @ 5/ha.

Pseudostem borer: Odoiporus longicollis

  1. Keep the field tidy by frequently removing dry leaves.
  2. Monthly side suckers pruning is necessary.
  3. Use healthy, pest-free suckers to measure the prevalence of pests.
  4. Keep infected items out of the manure pit.
  5. Cut into pieces and burn infected trees after uprooting them.
  6. Use 65/ha of longitudinally split pseudostem traps.

Banana aphid: Pentalonia nigronervosa f. typical

  1. Ensure healthy farming.
  2. Use healthy, pest-free suckers to measure the prevalence of pests.
  3. Eliminate diseased plants.
  4. Spray 0.05% of methyl demeton 25 EC.
  5. Encourage predator activity.

Cut worm: Spodoptera litura

  1. Pick up the caterpillar by hand and kill it.
  2. Gather and eliminate the damaged plant materials.
  3. The pupae should be exposed by summer ploughing.
  4. Employ a light trap.
  5. It is advised to use Chlorphyriphos or Azinphosethyl spray.
Plant diseases management

Anthracnose

  1. Fruits should not be harmed during harvest or transportation.
  2. Burn the contaminated items.
  3. It is important to maintain proper field sanitation.
  4. Maintain weed-free conditions and sufficient drainage in the field.
  5. Prior to being transported, stored, and allowed to mature, fruit has to be as infection-free as possible.
  6. Bunches of bananas should be picked when they are fully mature.
  7. The infection is avoided by proper fertilization.

Bunchy Top of banana 

  1. Use plant materials free of viruses.
  2. Identify diseased banana plants and remove them.
  3. Keep your field clear of weeds to allow for early detection of infected suckers.

Yellow sigatoka

  1. Taking out and destroying the damaged leaves.
  2. Keep the banana field as weed-free as possible, and promptly remove the suckers.
  3. Avoid sowing seeds too closely apart.
  4. Make sure the fields have enough drainage and prevent water logging, which encourages infection.
  5. Spray three times with Carbendazim (0.1%), Propicanozole (0.1%), Mancozeb (0.25%), and Teepol (sticking agent) at intervals of 10-15 days from the beginning of the incidence.

Panama wilt

  1. Select healthy suckers from disease fields when planting cultivators that are sensitive to the illness.
  2. After harvest, remove and eliminate any infected plant material.
  3. Application Along with farmyard manure and neem cake, Bacillus subtilis @ 2.5kg/ha bactericide can be used.
  4. You can insert around 60 mg of Bacillus subtilis (in a capsule) into a corm hole that is 10 cm deep.
  5. It is advised to dip the suckers in clay slurry and sprinkle them with 40g/corm of carbofuran granules.
Harvesting & post-harvest management

Bananas are picked unripe and given artificial ripening. While tall cultivars require around 14 to 16 months to harvest, dwarf cultivars are available for harvest 11 to 14 months after planting. After shooting, a bunch typically takes 90–120 days to develop depending on the temperature and cultural practises.The plant's height determines the harvesting technique. Cut through the bunch stalk around 30–35 cm above the top hand to harvest low-growing types. For taller varieties, the plant's stem will be partially removed to lower the bunch to the harvester's level.

Intercultural operation

Desuckering: Desuckering is the process of removing extra and undesirable suckers from banana plants.

Propping: Props are necessary to sustain the pseudostem during the moment of bunch emergence.Tall types that grow large bunches require props.

Mulching: Mulching is helpful in retaining soil moisture, increasing the number of feeder roots and so enhancing the efficiency of nutrient and water usage. It also inhibits weed growth, which increases the banana yield by 30–40%.
