EFEITOS DO HIDROGEL NA PRODUÇÃO DE ALFACE AMERICANA EM AMBIENTE PROTEGIDO

Abstract

Given the diversity of the irrigated area, there is a demand for water and, consequently, for the diversity of cultures. Irrigation efficiency plays a very important role in agriculture, being possible to use water correctly, wasted. The correct choice of high irrigation system for each selection will generate savings. As with existing irrigation technologies or the use of new ways of streamlining water, an example is the use of a water-retaining polymer, known as a hydrogel, which according to Mendonça et al., (2015), it has the capacity to retain 100 to 1000g of water per gram of polymer. This application was also used to work in two protected environments with the use of an irrigation system in two days, and another with an interval of four days, and with another type of control, which received the dose of polishing. It was noticed that lettuce is extremely sensitive to a possible water deficit, and that it was applied as the best daily irrigation. Only solids were as soluble (°Brix) as significant, as were the various grades and single acids, single acids, acids, pH and treatments applied.
