MAGNETIC AND ELECTROMAGNETIC TREATMENT OF WATER FOR IRRIGATION TOMATO CULTURE IN SALINE SOIL

Abstract

The increase demand for food has led to the inclusion of technologies that seek to optimize the production. Producers concerned about abrupt climate changes, such as torrential rain, hail, windstorms, and also pest attack protection, started to use protected environments for cultivation. One of the main crops grown in protected environment is the tomato, which has shown significant growth demand, due to be a tasty fruit, rich in nutrients, and high added value. Although, is sensitive to weather, salt concentration, pests and weeds. Tomatoes are demanding in fertilization during the cycle; thus, the producer adopts ferti-irrgation system for ease of handling and reducing the time spent. However, mishandling of fertilizers causes the process of soil salinization and thus generating various effects, from reduced productivity to infertility soil. These facts are originated from the increase of salt concentrations, which difficults the process of water absorption by the plant and causing a disturb in the biochemical and nutritional plant balance. Recent research showed that the water induced to the magnetic and electromagnetic field, presented a physical process that assists in water polarization, reducing the number of clusters and, thus, helping in the salt dissolution. Therefore, this proposal aims to mitigate the effects of the water treated magnetically, electromagnetically and potable in salinized soil for the tomato crop. The experiment will be conducted at the experimental farm at Faculty of Sciences and Engineering, Tupa Campus (FCE/UNESP). Randomized block design will be adopted, with three types of treated water and five different initial salinity levels (0, 1.5, 3, 4.5, 6 dSm-1), being the management based on monitoring of soil solution by installed extractors. Also, the studies will evaluate the biometric, biochemical, nutritional variables, gas exchange and tomato production. (AU)
