ABSTRACT
Studies related to the use of basic slag have become essential due to the possibility of use as a component of substrates in the production of seedlings and to minimize the risk of environmental contamination due to inadequate disposal. The objective of this research was to evaluate the effect of increasing levels of basic slag in substrates composed of soil, bovine manure, and sand on growth variables and quality of “Dedo de moça” pepper plants (Capsicum baccatum L.). A randomized block design was used, with five treatments of basic slag (0, 2.5, 5, 10, and 20%) and four replicates as treatments. The evaluations occurred at 55 days after sowing, consisting of counting the number of leaves, measuring plant height and stem diameter, and quantifying shoot and root dry masses. Regression models were adjusted (P < 0.05) in the treatments with increasing levels of basic slag. The addition of about 10% of basic slag in the substrate provided the highest values of growth variables in Dedo de moça pepper plants.
