Banana orchard management

Banana is considered as one of the most important staple food and forms an important crop for subsistence farmers. As a dessert fruit it is easy to digest and has rich source of carbohydrates with a calorific value of 67-137/100g fruit,it has rich source of  potassium,vitamin-c and minerals making healthy and salt free diet.

Climate and soil

           Banana is a moisture loving plant. It grows best in humid subtropical to semi-arid subtropics upto 2000 meter above mean sea level with a temperature of 15-35 c and a rainfall of 500-2000mm/year.

 

Banana is best suited in sandy loam soil with adequate organic matter. The orchard should be with proper drainage system as water stagnation leads to slow growth and plant collapse in extreme cases. It can also grow in slightly alkaline soil, such soil reduce wilt disease.

Cultivars:  Dwarf:  Dwarf Cavendish (Jahaji)                 

                     Medium tall:      Malbhog, Grand

                                                 Naine   

                     Tall:                     Manohar    

Spacing:  Dwarf : 1.5x1.5m

                 Medium:1.5x 1.5 m,1.5x1.8  m 

                  Tall :    1.8x1.8 m,2x 2m

Manures and fertilizers

           FYM : 12kg FYM/plant

         Fertilizers : 150 N: 40 P2O5: 300 K20/plant 

                  FYM should be applied at the time of planting, the whole of P2O5, half of N and K2O in the third month of planting, remaining N and K2O in the fifth month of planting.

Managemental practices during cultivation period:

          To have successful cultivation of banana, a good managemental practices of orchard should be followed at the right time:

•Removal of  weeds as and when required. 

•Removal of suckers in 45 days leaving only one to two suckers.

•Propping  up of pseudostem with bamboos at the time of bunch emergence especially in high wind velocity areas. 

•Practise of removing banana pseudostem after harvesting of  fruit.

•Removal of affected pest and disease leaf, dried leaves from time to time.

•Removal of male bud after completion of female phase as it improves in fruit size.

•Bunch covering with white polythene to overcome low temperature effect  

Crop cycle : 

One  main crop followed by 2 ratoon should  be allowed

Pest management

1.Rhizome borer :The grubs bore into the rhizome and feed within. The infested plant become weak, rot and lodge during heavy wind or rain.

Control :

1.Dip the rhizome in chlorpyrifos 20 EC at 2.5 ml/lt of water before planting.

2.Post planting- spray of chlorpyrifos 20EC at 2.5 ml/lt of water in pseudostem and drench around the base of the tree.

Stem borer : The plants infested by this  borer become weak,rot and breakdown during  strong blast of wind.

Control :

1.Clean cultivation prevents the pests.

2.In severe cases uproot and burn.

3.Spray Chlorpyrifos 20EC at 2.5ml/lt of water for 2 or 3 times at weekly interval.

Flea beetle:

    The beetle feeds on unfurled leaves, skin of young fruits making scratches which become wider as the fruit develops. The affected 

leaves and fruits become blemished, flavor is lost and reduce market value.

Control : 1. Adopt clean cultivation.

2.In severe cases spray Endosulfan 

      or Dichlorovos @0.5% in 1 lt of water.

Banana Aphids: 

   This pests infests on young leaves leading to leaf dwarfing, curling and fruit bunches become small and distorted. In severe cases it leads to bunchy top disease.

Control: Spray Dimethoate 30EC at 2ml/lt of water at fortnightly interval.

Disease management:

Panama wilt : Leaves of disease plants wilts and become yellow in colour. In severe cases  pseudostem and rhizome splits open. The rhizome exhibits vascular browning symptoms and gives a foul smell.

Control:   1.Adopt crop rotation

                  2. Provide proper drainage system

3.Dip the rhizome at 0.1% Carbendazim before planting followed by bimonthly soil drenching starting from 6 months after planting.

Banana (Sigatoka) leaf spot:

                The disease is characterised by appearance of small yellow spots on the leaf which becomes oval  and brown, coalesce to form large necrotic dark spots. Matured leaves are destroyed and only few functional leaves remain.

Control:  Provide proper drainage system

                Removed and destroy infected leaves Spray 0.1% Carbendazim at fortnightly interval

Bunchy top of banana: 

     The plants become stunted , inflorescence failed to form or the fruits fail to emerge from the pseudostem.

Control:  

 1. Avoid growing vegetables like tomato, pepper, cucumber, beans etc which are the alternate host of vector.

2. Uproot and destroy infected plants

3.Spray Rogor @ 2ml/lt of water.
