Bananas will grow in most soils, but to thrive, they should be planted in a rich, well-drained soil. The best possible location would be above an abandoned compost heap. They prefer an acid soil with a pH between 5.5 and 6.5. The banana is not tolerant of salty soils.

The large leaves of bananas use a great deal of water. Regular deep watering is an absolute necessity during warm weather. Do not let plants dry out, but do not overwater. Standing water, especially in cool weather, will cause root rot. Plants grown in dry areas need periodic deep waterings to help leach the soil of salts. Spread a thick layer of mulch on the soil to help conserve moisture and protect the shallow roots.

Their rapid growth rate make bananas heavy feeders. During warm weather, apply a balanced fertilizer once a month--a 8:10:8*NPK fertilizer appears to be adequate. A mature plant may require as much as 1-1/2 to 2*pounds of the above fertilizer each month. Young plants need a quarter to a third as much. Spread the fertilizer evenly around the plant in a circle extending 4 - 8*feet from the trunk.

Only one primary stem of each rhizome should be allowed to fruit. All excess shoots should be removed as soon as they are noticed. This helps channel all of of the plant's energy into fruit production. Once the main stalk is 6 - 8*months old, permit one sucker to develop as a replacement stalk for the following season. When the fruit is harvested, cut the fruiting stalk back to 30*inches above the ground. Remove the stub several weeks later. The stalk can be cut into small pieces and used as mulch.

Propagation of bananas is done with rhizomes called suckers or pups. Very small pups are called buttons. Large suckers are the preferred planting material. These are removed from vigorous clumps with a spade when at least three feet tall, during warm months. Pups should not be taken until a clump has at least three to four large plants to anchor it. When the pup is taken the cut must be into the mother plant enough to obtain some roots. Plant close to the surface. Large leaves are cut off of the pup leaving only the youngest leaves or no leaves at all.

The fruit can be harvested by cutting the stalk when the bananas are plump but green. For tree-ripened fruit, cut one hand at a time as it ripens. If latter is done, check stalk daily as rodents can eat the insides of every banana, from above, and the stalk will look untouched. Once harvested the stalk should be hung in a cool, shady place. Since ethylene helps initiate and stimulate ripening, and mature fruit gives off this gas in small amounts, ripening can be hastened by covering the bunch with a plastic bag. Plantains are starchy types that are cooked before eating.

Common salt can induce banana plants to yield more and better quality fruits.

Not only that: it can make the plants resistant to banana diseases.

This was found in a study done by researchers of the Department of Agriculture-Philippine Coconut Authority-Davao Researcher Center (DA-PCA-DRC).

The study, conducted by Millicent I. Secretaria, Severino S. Magat, and Marianita N. Eroy, was among the winners in the 2008 National Research Symposium (R&D competition) sponsored by the Bureau of Agricultural Research (BAR).

The researchers conducted a technology-demonstration trial on the use of common salt on cooking "Cardaba" banana under bearing Laguna Tall (LAOT) coconuts at the DA-PCA-DRC in Bago Oshiro, Davao City.

"The application of one kilogram of NaCl on the hole of stump of harvested banana adjacent to plants with developing inflorescence effectively controlled the incidence of "bugtok" disease of `Cardaba'," the researchers noted.

For the first time, they added, the trial confirmed the effective control of "bugtok" disease using common salt as reported in 2003 by researchers of the Central Mindanao University (CMU) in Musuan, Bukidnon.

The researchers observed "remarkable improvement in fruit quality and yield (increase over the control by 8.6 kg fruit per plant or 4.26 tons per hectare per cropping year)".

Nutrient analysis of banana leaves (at pre-flowering stage) showed that common salt application enhanced potassium (K) absorption from the soil, resulting in high K concentration in banana leaf tissue.

With one kilogram NaCl per stump of recently harvested plant, adjacent to newly flowering plant, different leaf nutrient levels of elements (nitrogen, phosphorus, potassium, calcium, magnesium, sodium, chloride, sulfur, boron, iron, manganese, copper, and zinc) are considered adequate for a productive "buktok" disease-free banana as intercrop in coconut farms, the researchers concluded. – Rudy A.
