Answer:
The banana is a perennial plant that replaces itself. Bananas do not grow from a seed but from a bulb or rhizome, and it takes 9 to 12 months from sowing a banana bulb to harvesting the fruit. The plants need rich, dark and fertile soils with steady moisture in the air and ground and good drainage.
Calcium are needed to ensure rotten root, leaf development, thereby providing high yields. Its effects are most important in ensuring high quality fruit with long term storage potential. Magnesium have a direct effect on yield, increasing the number and weight of fruit per banana bunch.
