India ranks second globally in fruit and vegetable production, with 18.299 million hectares yielding 311.715 million metric tons in 2021–22, contributing 28% to GDP. However, post-harvest losses (20–30%) and high prices limit accessibility, particularly in rural areas. To harness arid potential, vast wastelands offer opportunities for expansion. Key initiatives include ICAR’s 1976 ad hoc scheme on droughtDrought-resistant fruits and the 1978 AICRP on arid zoneArid zone fruits, leading to the establishment of the Central Institute for Arid HorticultureHorticulture in 1994. GermplasmGermplasm collection has conserved varieties like ber (42), pomegranate (24), and aonla (8), identifying resilient cultivars such as Gola ber and Bhagwa pomegranate. Propagation techniques, including grafting and cuttings, support nursery establishment for species like ber and date palm. High-density planting, drip irrigationDrip irrigation, and mulching improve water efficiency and yields, with systems like paired-row planting in pomegranate achieving 20–25 t/ha. Nutrient management via biofertilizers and fertigation enhances growth, while integrated pest management addresses issues like fruit flies and wilt. Post-harvest technologies reduce losses through improved handling and processing into products like ber candy and aonla murabba. Marketing via cooperatives and exports of kinnow and pomegranate boost income. Future potential lies in climate-resilient varieties, mechanization, and value addition, potentially increasing production and farmer incomes sustainably.
