How much distance of spacing in banana helps to get good bunch weight and quality?

At a spacing of 1.8×1.8 meters, place two plants per hole to double the yield with little or no effect on the size and maturity of the bunch on the crop in Dwarf Cavendish. Double planting of Robusta Bananas also increased profits. Calcium is needed to ensure root, leaf and sucking growth, thus providing high yields.
