The difference between banana variety Taijiao 5 and Beijiao, which has better disease resistance between Taijiao 5 and Beijiao?

"Taisao No. 5", commonly known as "Yushan", is the descendant of the great-grandson of "Bei Jiao". It is selected from the third generation of "Bei Jiao". In appearance, the parents and grandchildren are very similar. The height of the new plant is about 250cm 280cm, and the circumference of the pseudostem is 69cm 72cm, which varies according to the season. The weight of each bunch of fruit is about 20,000kg, and the winter banana (harvested from mid-January to mid-March) is lighter. Summer banana (from mid-June to late September) and some autumn bananas (from early October to mid-January) are heavier.

In Taiwan's main banana producing areas, banana plants can be planted in any month of the year, harvested after about 11 million months, and up to 15 months in the central mountains. "Bei Jiao" has a wide adaptability, but it is not resistant to banana yellow leaf disease. Planting in newly planted land or paddy fields after two or three years of crop rotation can reduce the incidence of disease.

"Taisao No. 5" is moderately resistant to yellow leaf disease and has a wide range of suitable species. As both of them are very similar in appearance and growth characteristics, they are also very similar in nutrient requirements. The amount of nutrients absorbed by banana plants growing for one year was about 150g of nitrogen (N), 40g of P2O5 and 560g of K2O. In addition to the failure, loss and removal of fruit clusters due to leaching, volatilization and fixation, most of the residual plants still remain in the banana garden to return to the banana garden in organic form, which can be reused as plants in the next stage after decomposition, so the actual amount of three elements needed for banana garden is not much every year.
