Boron deficiency in pineapples

Boron is a key element for proper nutrition of pineapple. Lack of boron can cause:

Malformed fruit
Broken core
Separation and cracking of fruitlets
Poor fruit set
Reduced sugar content

Few leaf symptoms have been reported. In very severe boron deficiency cases, the growing point may die, followed by profuse development of side shoots and suckers. Root growth is poor. Main roots may be brown and few fibrous roots are produced. The deficiency is more pronounced on the ratoon than on the plant crop.

Research has shown that boron amendments in pineapple affected by boron deficiency can increase sugar content, increase quality of fruit produced, and strengthen root and slip development. Boron has also been found beneficial when adding ethephon to induce flowering.

How much boron is enough?

Pineapple removes significant amounts of boron from the soil each year. Boron has a synergistic relationship with Ca, S, Zn, and K
Calcareous and alkaline soil can hinder the amount of boron available to the plant

Timing your boron application

Boron can be applied using foliar or soil applications. Ground applications of boron are recommended at 2kg B/ha every three years, with applications not to exceed 4kg B/ha.
Combining 0.25% Solubor^® with solutions of ethephon can help mitigate loss of sugar production from forced flowering.

Your boron fertilizer options

Granubor^® is an ideal material for dry blends applied to the soil
Fertibor^® works best in fertilizer suspensions for all soil broadcast applications
Solubor allows you the best flexibility for applying boron. It can be dissolved alone in water or in liquid fertilizers, and/or along with pesticides. It can be applied to the soil or directly onto the crop.
