Understanding Bearing Behaviour and Canopy Management in Different Fruit Crops

1. Aim

To study the bearing habit of different fruit crops and understand the appropriate canopy management practices required to improve fruit production and tree architecture.

2. Principle

Bearing behaviour refers to the location and type of buds that produce flowers and fruits on a plant. Different fruit crops bear fruits on terminal buds, lateral buds, spurs, or current season shoots. Understanding this behaviour is essential for proper pruning, training, and canopy management, as improper pruning may remove potential fruiting wood and reduce yield. Canopy management is the practice of manipulating tree structure to improve light interception, air circulation, and fruit productivity through training, pruning, growth regulators, and rootstock selection.

3. Materials Required

Fruit crop plants or orchard trees

Pruning shears

Field notebook

Tags and labels

Measuring tape

4. Procedure

Select representative trees of different fruit crops in the orchard.

Observe the position of flower buds and fruiting shoots on the tree.

Identify whether the crop bears fruits on terminal buds, lateral buds, spurs, or current season shoots.

Record the type of bearing habit.

Study the canopy structure and note the training or pruning method used.

Suggest suitable canopy management practices for each crop.

5. Observations

6. Result

Different fruit crops show distinct bearing habits, which determine the appropriate training and pruning methods for canopy management. Proper understanding of bearing behaviour helps in maintaining optimum canopy structure and improving fruit yield and quality.

7. Precautions

Avoid excessive pruning in terminal bearing crops.

Maintain balanced canopy for proper light distribution.

Remove diseased and overcrowded branches.
