ABSTRACT

Physiology of mineral nutrition refers to nutrient uptake, trans­ location, and assimilation or utilization by crop plants (Fageria, Baligar, and Jones, 1997). Biochemically, plant nutrition deals with complex biosynthetic events by which organic plant substances are produced from inorganic materials in the environment (Clarkson and Hanson, 1980). Factors for crop production such as water, cultivar, control of insects, diseases, and weeds, and mineral nutrition play key roles in increasing crop yields.
