Preventing Citrus Peel Plugging and Creasing
Creasing - the occurrence of narrow sunken furrows on the rind surface which makes processing more difficult as the peel disintegrates and is difficult to separate from the pulp and juice.
Plugging - the removal of the peel in the stem end area of the fruit leads to increased incidence of post-harvest
Crop Nutrition and Peel Plugging & Creasing
Potassium
Better potassium nutrition reduces the incidence of both creasing and plugging by improving peel integrity.
Calcium nitrate
Calcium nitrate is particularly effective at reducing creasing and plugging. In this trial CN halved the number of creased fruit and was more effective than calcium chloride.

Alongside nitrogen, potassium is one of the most important nutrients for citrus production. It is needed for enzyme activation, cell division, photosynthesis, photosynthate transport and osmoregulation.
Role of Calcium in Citrus Production
Calcium is a key component of cell walls and also has a direct influence on the regulation of enzyme systems, phytohormone activities and nutrient uptake.
Managing Citrus Peel Thickness
Peel thickness requirements vary depending on the citrus type and market needs. Thicker peels provide higher levels of oil extraction and offer a greater resistance against pests and better shelf life. Tailoring your crop nutrition plan will help to...
Preventing Citrus Albedo Breakdown
Albedo breakdown is the loss of cohesion in the cells if this white layer under the skin and any stress imposed on this as a result of expansion of the pulp can lead to rotting of this layer. It is also associated with creasing in the fruit. Good...
