The high density planting technique was first established in which crop in Europe? (IGKV CET Horti. 2017)

✅Explanation:
-High-density planting (HDP) is a technique where more plants are grown per unit area compared to traditional methods. It was first established in apple orchards in Europe during the 1960s.

✏️Apple trees respond well to HDP due to their ability to be managed through techniques like:
-Dwarfing rootstocks: These are root systems that control tree size, allowing for closer planting.
-Pruning: Regular pruning helps maintain desired tree size and light interception for fruit production within the HDP system.

✏️Related Terminology:
-High-density planting (HDP): A method of planting crops with a significantly higher plant population per unit area compared to traditional spacing.
-Dwarfing rootstock: A root system specifically bred to control the size of a grafted tree, allowing for closer planting in orchards.
-Pruning: The selective removal of plant parts to promote healthy growth, fruit production, and maintain desired tree size and shape in HDP systems.
