Resumo: | ABSTRACT This study aimed to evaluate the use of hydro polymer retainer in the quantitative growth of coffee plants at different levels of irrigation and soil types. The experiment was conducted in pots with seedlings bag in the greenhouse of the Setor de Cafeicultura, Universidade Federal de Lavras. The experimental design was in randomized blocks in factorial (2x4x2): absence or presence of hydro polymer retainer, four levels of irrigation (25%, 50%, 75% and 100%), two soil types (sandy soil and medium texture). At 150 days evaluated the stem diameter, plant height, leaf area, number of leaves, dry weight of shoots, plant dry mass, root dry weight, root dry weight ratio of shoot, leaf area ratio, absolute growth rate, relative growth rate, net assimilation rate and leaf area index. It was concluded that the polymer hydro retainer hydrated favored the growth of coffee plants and irrigation promoted greater growth of coffee in medium textured soil compared to soils with sandy texture.
