ABSTRACT
The tomato plant continues to play a major role in plant physiological studies, studies that are revealing the basic principles of plant physiology and nutrition. The tomato plant is relatively easy to grow, is responsive to changing environmental conditions, and has a fairly high nutrient element requirement. Due to its frequent common use in the past as a physiological indicator plant, considerable data have accumulated that can be referenced in newly emerging findings. Based on its known physiological characteristics, the tomato plant continues to be used as an indicator plant (see page 32). This chapter deals with the mineral nutrition of the tomato plant as it is known today and how this knowledge is being put to use in the production of tomato fruit.
