Nepal has favorable agro-ecological diversity of fruit crops ranging from tropical to temperate species. Fruit crops are the perennial edible crop which may be deciduous and drupe or evergreen. High density planting is defined as the accommodation of the maximum possible number of plants per unit area to get the maximum possible profit per unit of the volume without impairing the soil fertility status. Apple, citrus, mango, banana, guava, and papaya are the major fruits cultivated in different agro-ecological zones of Nepal. Higher yield with the better quality can be achieved when the orchard has good light distribution throughout the canopy and there is a balance between vegetative growth and fruiting. The underlying principle is to make the best use of vertical and horizontal space per unit time and per unit area. The use of dwarfing rootstocks, efficient training and pruning as well as the use of plant growth regulators and suitable crop management practices are the basic components of high-density planting. In context of Nepal, high density planting is successful in different fruit crops like apple, pear, banana, guava, litchi. Highest fruit weight along with the highest yield was recorded.
