Tomato crop fertilization -a undisputed benefit for efficient production at an expected level

Abstract

Because the plant is a symbiosis of two systems, one heterotroph with one autotroph, respectively the root with the aerial part, it is the projection of a somewhat differentiated and yet unitary metabolism, and at the same time, a "barometer" of the nutrition state. The nutritional disorders are thus, in close agreement with the vegetation but also nutrition factors, especially in relation to the fertilization practices. Along with the dosage of the movable elements in the soil, the foliar diagnosis represents the main and efficient method to complete the necessary elements. nutrition, in different developmental phenomena. The paper presents results of foliar diagnosis, at a crop of tomatoes in the field, at two critical moments of nutrition, before flowering and at the beginning of ripening. The obtained results, regarding the state of ensurance with macroelements, certify the need for additional fertilizer intervention and guarantee the obtaining of harvests at an expected level.
