- Abstract
Zeolite-clinoptilolite is a hydrated aluminosilicate, which belongs to a group of minerals of volcanic origin and possesses interesting agricultural properties. The aim of this study was to determine the effect of zeolite-clinoptilolite on Solanum lycopersicum Mill. seedling growth, when supplied to substrate in pot culture. An assay was set to test and compare the physical properties of three substrates: peat moss (pm), perlite (per) and zeolite (zeo), and their mixtures (pm:per:zeo) at different proportions: T1 or control = 100:0:0; T2 = 70:30:0; T3 = 70:20:10; T4 = 70:10:20 and T5 = 70:0:30 (v/v). Compared to control plants, substrates containing 30% zeolite increased their water holding capacity (260%), total porosity (8.47%), bulk density (212%) and particle density (230%). Related to control plants grown with 100% peat moss, tomato seedlings cultured in a substrate mixture with 30% zeolite significantly improved shoot length (24.2%), leaf area (64.5%), root length (63.2%), shoot dry weight (62.5%), root dry biomass (208.9%), stem diameter (28.5%) and leaves number (92%), however, the chlorophyll index had no significant effects. The overall outcomes indicated that substrates amendment with zeolite could effectively improve tomato plants growth.
