High planting density is considered one of the modern management systems in new fruit orchards. Pruning and population adjustment are some of the main way to approach high productivity and good fruit quality under the modern management systems.
Pruning is defined as the management of plant structure and fruiting wood and it is considered one of the main factors affecting fruit trees production. There are many objectives for pruning i.e. controlling the direction of growth, developing a strong framework, controlling the amount of growth, improved productiveness, improving quality product, utilizing space efficiently and increasing the usefulness of plant. There are three main systems of fruit trees training (i) Central leader system, (ii) Modified leader system, (iii) Open center or vase system. Also there are several kinds of pruning i.e. heading back and thinning out, fine and coarse pruning and root pruning. However, it is important to select the suitable training system and kind of pruning according to the target of the pruning to reach optimum vegetative growth and maximum yield with high fruit quality.
On the other hand, population adjustment (plant distribution or planting density) is very important factor affecting fruit trees production. We can reach the optimum usefulness of the planted area by using best population adjustment of trees in the plantation. Trees can be planted using different systems:- triangle, rectangle, square system…..etc. On the other side, presence of pollinator trees through the orchard is very important for many fruit trees. Pollinator can be planted either in (1) Complete along rows, as one row of pollinator per two or four rows of the main cultivar. (2) The second tree in the second row. (3) The third tree in the third row. (4) Across rows through the orchard. On the other hand, good plant distribution is very helpful for mechanical serves in the plantation,
We can say that the key objective in planning a new orchard should be to maximize yield in the early years and still effectively produce larger yield of high quality fruits in the next years. This may be happened by utilizing space efficiently and increasing the usefulness of plant using the suitable training system, kind of pruning, also good population adjustment of the trees in the orchard beside the importance of the other factors affecting production process.

Excerpt from the Book
1.1.2 Balance of roots and top
Plant growth, development, and reproduction are influenced by the ratio of roots to top. Reduction of leaf area in the growing season or reduction of the number of buds in the dormant season has little effect on root area, but a reduced number of growing points results in stronger shoots with larger leaves. Increase leaf area increases transpiration and photosynthesis, and puts more demands on the roots. However, root pruning reduces the absorbing area, slowing top growth. Stored food is utilized to replace roots, and top growth dose not resume immediately after root replacement since manufactured food must first be stored in the stem. Proper pruning affects a balance of top and roots.

Frequently Asked Questions
What is the primary focus of this article?
The article serves as a review of management practices in fruit orchards, specifically focusing on how pruning and population adjustment are used to influence tree productivity and fruit quality.
What are the main thematic areas covered?
The main themes include pruning techniques (training, thinning, root pruning), the use of chemical regulators, the effects of planting density, and the importance of tree arrangement in orchard planning.
What is the core objective of the research presented?
The primary goal is to identify methods for maximizing yields in early orchard years while maintaining effective production levels and high fruit quality in later years.
Which scientific methodology is employed?
The work utilizes a literature review approach, summarizing and synthesizing findings from various horticultural studies and experiments on different fruit tree species.
What topics are discussed in the main body?
The main body covers the principles and objectives of pruning, specific types of pruning (heading back, thinning out, root pruning), special practices like dehorning and fruit thinning, and detailed strategies for population adjustment.
Which keywords best characterize this work?
Key terms include pruning, population adjustment, fruit trees, planting density, training systems, crop load, and orchard management.
How does root pruning influence a fruit tree's development?
Root pruning reduces the absorbing area of the tree, which can help in checking over-vigorous growth, though it often leads to decreased total yield and fruit size in certain species.
What is the relationship between light distribution and planting density?
High planting density requires careful management of row spacing and tree height to ensure that total light interception is maximized while maintaining good light distribution throughout the canopy for higher fruit quality.
