Effect of far-red light on improving yields of tomatoes produced in vertical farms

Tomato (Solanum lycopersicum L.) is one of the major crops cultivated globally and one of the most important vegetable crops in the world. While open field production is the primary method for producing freshly consumed tomatoes, protected environment production has seen rapid expansion in recent decades. Vertical farming is gaining interest as a potential production method. This chapter focuses on recent research published in Ji et al. (2019, 2020, 2021) on the physiological and molecular mechanisms by which far-red radiation increased tomato yield. Subsequently, we discuss the possible applications of this knowledge to vertical farming and the key aspects for a dedicated breeding of tomatoes varieties suitable for growing in vertical farms.
