Resumo: The objective of this work was to evaluate the chemical alterations of the substrate in the cultivation of pepper in coconut husk fiber, in a protected environment. Initially, 160 pepper plants ('Eppo') were divided into four blocks, where two pots per block were analyzed every 21 days after transplanting. The cultivation of pepper was carried out in plastic pots of 13 L, containing coconut husk fiber, and placed in double rows with a spacing of 0.5×0.8 m between single rows and 1.10 m between double rows. After removal of the plants from the pots, individual samples of substrate (approximately 1 L) were collected from each pot and dried at ambient temperature. Electrical conductivity (EC), pH, and levels of NH4 +-N, NO3 -, P and K were determined for all periods of the cultivation. These analyses were performed using the method of extraction 1:1.5 v/v. For the conditions which the experiment was conducted, there was an increase in substrate EC, as well as in the levels of nitrogen, phosphorus and potassium.
