Crop/Growth management

Managing crop load in deciduous trees (part 5)

Benefits of chemical thinning: To achieve good thinning and fruit quality, all chemical thinners need to be applied at the appropriate physiological stage and under the climatic conditions best suited to each chemical. Choice of thinning chemical is important, as some cultivars do not respond well to some chemicals.

Effect of temperature at bloom on fruit set in Williams’ pears

In the early 20th century, researchers in California, Germany, South Africa and Australia reported that Williams’ fruit had no seeds. The full name of the variety, Williams’ Bon Chretien, is also referred to as WBC or Bartlett. The term parthenocarpy was introduced, and is defined as the development of fruit…

Managing crop load in deciduous trees (part 2)

Why is early crop load management so important?The natural fruit drop observed in fruit trees, particularly apples, in early summer is insufficient to achieve optimum crop loads, fruit size and quality, or to prevent biennial bearing.

Nectarine colour development & quality (part 2)

Observations: Fruit size was not affected by light exposure or tree side, only by the number of fruits, with the low crop load showing the bigger fruit, as expected.Blush colour was affected differently by the light exposure and tree side.

Managing crop load in deciduous trees

Irregularity in cropping is a major economic constraint in many fruit tree orchards. Understanding the mechanisms involved in flowering and fruit set can help orchardists to manage crop loads, resulting in improved yields, fruit quality and returns.
