TORRES-GONZALEZ, Jorge Alejandro et al. Industrial Raw Mud Application in Greenhouse Lilium sp. Production. Terra Latinoam [online]. 2011, vol.29, n.4, pp.467-476. ISSN 2395-8030.

In order to verify the potential use of agricultural textile industrial waste its incorporation was evaluated as growing medium for ornamental production of Lilium sp. potted plants grown in greenhouse conditions. A complete randomized experimental design with fifteen replicates was used; treatment concentration was 2, 5 and 10% of mud mixed with peat moss (volume/volume) and a control without mud. Stem diameter and length, flower diameter and length and minerals such as N, K, Ca, Mg, Fe, Zn and Cu, and heavy metals Pb, Cr, Cd, Ni and Al concentrations on plant tissues were analyzed. In addition, anatomic characteristics of stems, parenchyma area, cell and xylem vessel area and frequency, were also evaluated. The results indicated a negative effect of mud over stem diameter (P ≤ 0.01) and a positive effect of mud over stem length (P ≤ 0.05), flower diameter and length (P ≤ 0.05). Levels of minerals in plant tissues were normal whereas heavy metal concentrations did not exceed toxic levels. The plants did not show deficiency or toxicity symptoms induced by the presence of mud. Parenchyma area cell and xylem vessel area and frequency had significant differences (P ≤ 0.05), the study showed a correlation between anatomical characteristics and morphological traits (r = 0.8258; P ≤ 0.05). In conclusion, it is feasible to use textile industrial mud in Lilium sp. production and it is a viable option to decrease mud quantity when it is improperly confined because it could contribute to environmental pollution and soil deterioration.
