Agricultural and Horticultural Lighting

Abstract

One of the earliest reports on the usage of artificial lighting in horticulture dates from before the invention of the incandescent lamp. Horticulture in controlled and closed environments is one of the most energy-intensive cultivation systems in agriculture. Artificial lighting is an important part of it. Its use allows for year-round production of quality vegetable, fruit, and ornamental crops independent of weather conditions and geographic location. This chapter reviews the main aspects involving the usage of horticultural lighting considering the challenges faced by the horticultural industry in the context of a food- and energy-hungry world.
