A comprehensive review on high-density planting in fruit crops and its implications

Abstract

India’s fruit productivity remains significantly lower compared to many horticulturally advanced nations, largely due to senile orchards, inferior planting materials, inadequate orchard management, and limited adoption of modern technologies. With rising land and labour costs and increasing consumer demand, High-Density Planting (HDP) systems have gained momentum as an efficient and economically viable approach to fruit cultivation. HDP allows maximum utilization of horizontal and vertical space by accommodating more plants per unit area, resulting in reduced juvenile period, enhanced productivity, uniform canopy structure, improved fruit quality, and higher profitability. The success of HDP depends on precise control of vegetative growth, efficient canopy management, and optimal light penetration. This review compiles up-to-date information on suitable cultivars, rootstocks, planting densities, pruning techniques, growth regulators, and other management practices essential for establishing and sustaining high-density orchards across major fruit crops.
