There is controversy about the benefits of silicon (Si) on tomato
plants. This element has structural and metabolic functions in the
physiology of plants, generating benefits that may result in increased
productivity of various plant species. Thus, the aim of this study was
to evaluate the phytotechnical characteristics and the productivity of
tomato plants according to the rates and sources of Si. The design was
established in randomized blocks with factorial 3x5, corresponding
to three sources of silicate (calcium silicate, potassium silicate and
sodium silicate) and five doses of Si (equivalent to 0, 100, 200, 400
and 800 kg ha-1 of SiO2). The fertilization with Si increased the
commercial productivity of tomato plants and reduced the occurrence
of cracked fruits. Calcium and potassium silicates increased the Si
levels on the leaves linearly with the increase of the doses, while
sodium silicate reduced the levels in larger doses. Silicon fertilization
increases the productivity of tomato plants with possible economic
return on the use of this input.
