ABSTRACT

Citrus species mainly mandarin, sweet orange and lime are major fruit crops of Nepal. Government of Nepal has given high priority for research and development (R and D) of citrus in mid-hill region of the country. Since 1960s systematic R and D efforts were made from public sector resulting to evolution of various institutions including donor aided projects to commercialize these crops. Technologies are generated on variety improvement, nursery management, orchard husbandry, plant protection and post harvest aspects. Commercial production has been expanded to nearly 50 districts of the country. Despite all the efforts Nepal is still importing significant quantity of citrus fruits annually. In this context, this chapter presents various research activities undertaken in the past along with their significant results. Additionally, extension and technical delivery mechanism and production and export- import trend are also briefly stated.
