Tissue cultured banana seedlings should be selected for planting under precision farming. The tissue culture plants maintains uniformity, fast growing nature and about 20 days earlier in flowering and about 35 days shorter crop cycle with significantly higher yields than suckers. The following points should be considered for the selection of tissue cultured plants.

Proliferation of tissue culture seedlings |
Poly bag filled with soil and potting media |
Seedlings with five leaves |
A well hardened plant with minimum of 30 cm in height and should have a pseudo stem circumference of 5.0 – 6.0 cm after 45 – 60 days of hardening should be selected.
The plant should have 5 photo synthetically active leaves and inter foliar space must be not less than 5.0 cm.
The plant should have approximately 25 – 30 active roots at the end of secondary hardening stage.
The length of active roots should be more than 15 cm with a good number of secondary roots.
The poly bag should be of size (20 cm in length and 16 cm in diameter) with potting media filled to ¾ full of the bag.
The media / potting mixture approximately should weigh about 750 – 800g on dry weight basis.
Plant lets should be free from any visual symptoms of leaf spot, pseudo stem rot and physical deformations.
Plant lets should be free from the presence of root pathogens like erwinia rot symptoms, nematode lesions and root knots. Random checking of roots is very essential at the time of procurement.
Those exhibiting abnormal growth must be discarded.

In Precision Farming, irrigation is done by drip irrigation system. In sandy loam soil, laterals may be placed @ 6 feet spacing and the drippers of 50 cm or 60 cm may be selected and the water delivery of 3.5 and 4.0 liters per hour respectively. This 6 feet lateral spacing is suitable only for banana.
The lateral spacing of 150 cm may be fixed and planting may be done in the spacing of 5 × 7 feet distance.
Water requirement for banana plants is about 900 – 1200 for its total duration. For better growth and productivity optimum moisture at all stages of growth and good drainage facility to drain out excess water from the root zone.
Under drip irrigation, water is allowed to reach the root zone of the crop in small quantities. Stage wise water requirement of banana is given below
Fertigation is the technique of précised application of dissolved fertilizer to the crops along with irrigation water through appropriate injection device. Through drip irrigation, the water soluble fertilizers and other nutrients can be precisely applied to the soil at appropriate times in desired concentration. These nutrients being placed around the plant roots uniformly and facilitates rapid uptake of nutrients by the plant
Water Soluble Fertilizers can be injected into irrigation systems by three principal methods.
Water flowing through the venturi creates a suction that draws the fertilizer solution into the line. This injection method is inaccurate because pressure and flow rates vary in a drip irrigation system.
The fertigation tanks of different sizes viz., 60 l, 90 l, 120 l etc., can be used for fertigation. The pressure difference exists in the input and out put valves sucks the nutrient solution from the tank and pass on to the irrigation pipes.
These inject fertilizer directly into the drip irrigation pipes at a uniform rate. Small electric pumps draw a known volume of solution and force it into the irrigation line.

All the commonly available fertilizers may not be used in fertigation since, they are not 100% soluble. The water soluble solid or liquid fertilizers are highly suitable and the selection of these fertilizers have to meet the following criteria:
Tissue cultured banana responds well under fertigation and requires 50 per cent extra fertilizers than the suckers planting under conventional system. Application of 200-30-300 g of N: P2O5:K2O /plant using water soluble fertilizers through fertigation is essential. Fertigation should be done at five days interval as per the following schedule
Three important points should be noticed For effective fertigation scheduling

Optimum growth of plant is governed by the availability and use of natural resources of land, water and sunlight.
In general, greenhouse cultivation could be considered as protected cultivation that enhances the maturity of crop, increases yield, improves the quality of produce and in some instances reduce the use of pesticides. The use of greenhouse technology also reduces the total time for preparation of seedlings and cuttings significantly. Greenhouse is also essential for plant propagation through tissue culture.

Dry leaves mulching |
Mulching is a practice of covering the soil surface around plants to make conditions more conducive for plant growth. Use of dry leaves, straw, hay, stones etc. as mulching material has been prevalent for ages. However, introduction of plastic film as mulch increases the efficiency by improved moisture conservation, increased soil temperature and elimination of weed growth and hence, increase in crop yield. Mulch is also used for soil solarization. It helps to maintain favourable soil temperature during daytime and retains it during night.
Spade digging and earthing up of plants are done after applying 20 g of Furadan + ½ kg Pungam oil cake at 3 MAP.

Bananas are generally mature on 100 to 110 days after shooting of bunches. The fruit bunches are harvested when the angularity of fruits disappears. Mature bananas are not harvested when they are yellow; they are harvested while they are still green, but with a slight yellow tint, which is hardly noticeable. The flower bract is dry and breaks off easily from the fruit tip. When tapped the fruit gives metallic sound. One week before of harvesting, should stop irrigation to the field because it reduces the fruit quality and storage period. Harvesting is to be done based on the selection of market and maturity of banana. Suppose you are going to sell the bunch in local market, harvest at 80-85% maturity and for exporting, harvest at 75% maturity.
For banana harvesting, one or two workers are needed namely a cutter and a backer. In a large operation, there will be two workers, both the cutter and a backer. In a smaller operation, one person could do the harvesting of banana trees. The cutter is responsible for cutting the banana cluster, cutting down the plant and chopping the stem. After cutting the banana cluster the backer will carry them to the storage shed.
It is one of the advanced technologies in banana harvesting. In this technology, cut the hands separately from the bunch by using thin nylon rope. Put the rope in between the bunch and hands. Then, the hands will be separated easily by pulling the rope. In this method, harvesting is done easily and there is no damage on hands. It is easy to pack and transport to different places.
Bananas can be stored for up to a week in a cool place but unripe bananas should not be stored in the refrigerator, as this may irreversibly interrupt the ripening process. If the banana is no longer green it is ripe and can be stored for a maximum of one week. For storage, banana should be stored at 13° to 14°C
Bunches should be kept out of light after harvest, since this hastens ripening and softening. For export, hands are cut into units of 4 -16 fingers, graded for both length and girths and carefully placed in poly-lined boxes to hold 12 to 18 kg depending on export requirement. Prior to packaging fruits are cleaned in water or dilute sodium hypochlorite solution to remove the latex and treated with thiobendazole.

After separating hands from the bunches, wash the hands in running water to remove the latex. So, the appearance of fruit will be improved. Then, the fruits are dried in open space and taken to cooling chamber.
The hands are graded based on the number and size of fingers in each hand. Overripe and injured fruits are discarded at this stage. Banana is sent to the local market as bunches.
Storing of banana fruits in unvented polybags at low temperature could extend the shelf-life of the fruits. The fruits are stored at 13.5°C in the cooling chamber with 90 to 95% relative humidity. So, the fruits will be kept as unripe and maintain the quality for 20 days. Maintaining ethylene concentration below 1 ppm can extend postharvest life of mature green bananas. Mature-green bananas can be stored for up to 3 weeks in ethylene-free air or up to 6 weeks in a controlled atmosphere at 14°C.
The cluster approach is adopted for operational conveniences and to ensure better logistics. This rendered support to collective marketing and mutual consultation and discussions.

1.How many members are joined to form a cluster?
20 - 25 farmers are joined together to form a cluster. Each farmer possess minimum one hectare of land (2.5 acres) and he is considered as one unit.
2.Is the cluster is scattered or in one place?
The clusters are from one revenue village. If not from two neighbouring villages but not in scattered manner.
3.What is the minimum requirement to join in the cluster?
Each member should have minimum one hectare of land.
4.Is there any possibility to join the farmers having below one hectare of land?
Yes, two or three farmers having less than one hectare can join together and avail one hectare with common water facility.
5. How the clusters are registered as associations?
The group of farmers jointly together as cluster and register as association in registrar of society act.
6. How much subsidy they get from government?
The clusters able to get 65% subsidy from the government. The government gives 40% subsidy as cash and the remaining 25% subsidy as inputs like seeds, fertilizers and pesticides. The clusters approach any company for drip instatallation and submit the quotation to the government. Based on the quotation submitted, the government will give 40% cash subsidy to the clusters.
7. What are the benefits of cluster approach?

These merchants either make outright purchases on cash basis or act as commission agents.
The banana farmers need the long term security of fair and stable prices for their fruit in order to continue thefarming sustainably.
They also need additional investment income for tackling poverty and improving their communities.
For this, the farmers form the clusters and federations at state level. So they will attain social, economical and political empowerment.
The precision farmers form federations at state level and registered.
From this associations, the farmers strengthen the commodity group based activities, conduct periodical group interactions.
Technical knowledge have been equally shared among all the members.
By getting high yield, they improve social status in their society.
