Resumo
The objective of this work was to perform an analysis of the cost and performance of crisp lettuce in a protected model, with different levels of irrigation and different doses of hidrore-tentora solution. The work was carried out in the experimental area of Goiás Federal Institute-Campus Urutaí-GO, geographic positions are latitude 17º29'10 S, longitude 48º12'38 W and altitude 697 m, excluding the period from December 2017 to January 2018 (4x5), with subdivision of blocks using four levels of irrigation (50, 75, 100 and 125%) of the evaporation obtained daily, to tank Class A and five doses of hydrogel solution (0, 50, 100, 150 and 200 g). The product was analyzed with the advantage of having achieved, during the productive cycle, productive changes and efficiency in water use (USA). Irrigation levels and doses of hydrocor-tisone solution may significantly influence PRO and US variables. Profitability increased with the increase of irrigation slides and decreased with the use ofhydrogel.
