Abstract

The water crisis is a reality and the demand for food is increasing, which encourages researchers and producers to insert new technologies in agriculture in order to optimize production. One of the main plants cultivated in a protected environment is tomato, which has been expressive growth in its demand, being a tasty fruit, rich in nutrients, and high added value. However, it is sensitive to the climate, concentration of salts, pests and weeds. The tomato is demanding in fertilizations throughout the cycle; Thus, the farmer adopts the fertigation system to facilitate management. However, the incorrect management of fertilizers causes the process of salinization of the soil, causing several consequences, from reduction of productivity to soil infertility. These facts are due to the increase in the concentration of salts, which hinders the process of water absorption by the plant, generating the biochemical and nutritional imbalance of the plant. Recent research indicates that when water is induced to the electromagnetic field, a physical process occurs that assists in the polarization of water, reducing the number of clusters and assisting in the dissolution of salts. Thus, this project aims to mitigate the effects of electromagnetically treated water in salinized soils for tomato crop. The experiment will be conducted at the Experimental Farm of the Faculty of Sciences and Engineering, campus de Tupã (FCE / UNESP). A randomized block design with two types of treated water and five different levels of initial salinity (0, 1.5, 3, 4.5, 6 dSm-1) will be adopted, being the management based on soil solution monitoring Through the installed extractors. Biometric and biochemical variables will be evaluated. (AU)
