- Abstract
Tomato is one of the most economically relevant vegetables worldwide. However, its production can be limited by several factors, with water management being the main limiting factor. Thus, the use of technologies that improve efficiency in the use of water are extremely important, with emphasis on the use of hydrogel. In this sense, the objective of this study was to evaluate the growth and production rates of tomato under irrigation depths and hydrogel volumes. The experiment was carried out in a 3x4 factorial scheme, in randomized blocks with four replications, with the following factors: three volumes of previously hydrated hydrogel (0, 50 and 100 ml per plant); and 4 irrigation depths (40, 60, 80 and 100% evapotranspiration of the crop). The absolute and relative growth rates of plant height and stem diameter, average fruit mass, and productivity per plant were evaluated. The results showed that the reduction of irrigation depths led to a linear reduction in absolute and relative growth rates in both height and diameter. Under these same conditions, there was also a reduction in the average fruit mass and productivity per plant. The use of hydrogel did not affect any of the evaluated characteristics; therefore, it is recommended not to use it under the conditions of this study. It is recommended to use the 100% ETc replacement blade.
