【 摘 要 】
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.
