Optimum spacing for high density G9 banana

I am first time in banana farming. Can anyone pls help with the high density spacing for g9. It will be on drip.

I was thinking of paired row (1.21.22 Mt). Is it advisable to go for paired row or more dense combination.

Spacing

Traditionally banana growers plant the crop at 1.5m x 1.5m with high density; however plant growth and yields are poor because of competition for sunlight.
The region like north India, coastal belt and where humidity is very high and temperature falls down upto 5-7ºC, the planting distance should not be less
than 2.1m x 1.5m.

Season          Spacing
Kharif            1.5 x 1.5 m., 2 x 2 m. or 2.5 x 2.5 m.

Rabi                1.5 x 1.2 m., 1.5 x 1.37 m.

Banana planting is carried out on the basis of patta double line method. In this method, the distance between the two lines is 0.90 to 1.20 m. while plant to plant distance is 1.2 to 2 m. Due to this spacing, intercultural operations can be carried out easily and cost of drip irrigation is decreased. Experiments carried out recently show that good quality banana and heavy bunch can be achieved by keeping the planting distance at 1.8 X 1.8 m. However, to get maximum yield plantation is done at 1.2 X 1.5 m.

[color=red]Ultra High Density Planting[/color] : High density planting is in practice to accommodate 4444 to 5555 plants per ha. and yield of plants is recorded to be in the order of 55-60 tonnes/ha. or even more. In general square or rectangular system of planting is a common practice followed by the cultivators. Planting 3 suckers / pit at a spacing of 1.8 x 3.6 m. (4,600 plants per ha.) for Cavendish varieties and 2 x 3 m. for Nendran (5000 plants per ha.) varieties are also followed.

Application of irrigation through drip system helps to maintain the proportion of soil air and soil water which results in early and vigorous growth of bunches. Raw bunch gets matured earlier by 30-45 days and yield is increased by 15-30 % and 58-60 % of water is saved on irrigation, weed is less, cost on intercultural operations is saved and water soluble fertilizers can be applied.

Drip irrigation may be given @ 15 l. /plant /day from planting to 4th month , 20l. /plant/day from 5th month till shooting stage and 25 l./plant/day from shooting till 15 days prior to harvest.

Two methods are followed in case of drip irrigation:

i)      Single line system : The spacing between the plants is 1.5 X 1.5 m. One lateral line and one dripper per plant is used.
ii)      Double line system : The distance between the lines is 1 m., between two plants is 1.5 m. and between two double lines is 1.8m. each. One lateral and one dripper for two plants are arranged. The distance between the two lines may also be 2.1 X 2.4 m.
