This work aimed to verify the effect of coffee without irrigation of the planting season using the hydro retainer polymer in the initial plant growth. The experimental design was a randomized block, factorial design, with three replicates. The treatments consisted of six planting dates: October, November, December 2012, January, February and March 2013, as well as presence and absence of hydro retainer polymer applied in the planting hole. Two evaluations were carried out, these in July 2013 and January 2014. It was evaluated plant growth and mortality in the field in function of time of planting and the use of hydro retainer polymer as soil conditioner. A higher growth of plants taken to the field at the beginning of the rainy season compared to other periods, showing that the planting season is crucial that formation period in respect of growth and a possible anticipation of production in later years. Regarding the use of the polymer, it was important to reduce the mortality of plants at the end of the rainy season.
