          Abstract

          Com o intuito de contribuir com os dados disponíveis na literatura sobre tolerância das culturas à salinidade do solo oriunda de sais fertilizantes, o presente trabalho tem, como objetivo, determinar a tolerância da cultura do tomate a salinidade do solo, a partir de dois manejos de fertirrigação e seis níveis iniciais de salinidade (1,0; 2,0; 3,0; 4,0; 5,0 e 6,0 dS m-1) a partir das variáveis produção e componentes de produção, em ambiente protegido com solo franco-argiloso. O experimento foi realizado no Departamento de Engenharia de Biossistemas da ESALQ/USP, Piracicaba,SP. O delineamento estatístico foi aleatorizado em blocos, com 4 repetições, concluindo que a produção e os componentes de produção da cultura do tomate foram afetados estatisticamente, tanto pelo tipo de manejo de fertirrigação quanto pelos níveis de salinidade do solo, com redução na tolerância da cultura do tomate, passando a ser classificada sensível à salinidade do solo.

          Translated abstract

          In order to contribute to data available in the literature on tolerance of crops to soil salinity derived from fertilizer salts, the present study aims to determine the tolerance of tomato crop to the soil salinity, based on two managements of fertirrigation and six initial levels of salinity (1.0; 2.0; 3.0; 4.0; 5.0 and 6.0 dS m-1) from the variables production and components of production, in a protected environment with sandy-clay soil. The experiment was conducted at the Department of Biosystems Engineering of ESALQ/USP, Piracicaba/SP. The experimental design was in randomized blocks, with 4 repetitions. Concluding that the production and the components of production of tomato crop were significantly affected both by the type of management of fertirrigation and by the levels of soil salinity, with a reduction in the tolerance of tomato crop, being classified as sensitive to soil salinity.
