Enhancing Growth and Sustaining Variegated Properties of Ornamental Plants through Zeoponic Formulations

Abstract

Abstract Variegated ornamental plants, known for their diverse leaf colors and high market demand, present a unique challenge in preserving long-lasting aesthetic appeal. This study focuses on the development and optimization of zeoponic formulations as effective plant growth media (PGM) to promote sustained growth and visual excellence in two variegated ornamental plants, Epipremnum aureum “Marble Queen” and Peperomia obtusifolia “Green Gold”. Zeoponics, composed of zeolite, compost, cocopeat, and fertilizers, is chosen for its high Cation Exchange Capacity (CEC) and aesthetic appeal due to its greenish-grey zeolite grains. Through greenhouse pot experiments and comprehensive PGM analysis, specific zeoponic formulations were identified for each plant species, yielding the most favorable results in terms of growth and appearance. The research explores the chemical properties of PGMs and observes plant growth parameters and chlorophyll content using Soil Plant Analysis Development (SPAD) measurements. The results show that the best formulation of fertilizer types and dosages for Epipremnum aureum “Marble Queen” is zeoponic Z7, with 10% Fe-EDTA, 10% Cu-EDTA, 10% Mn-EDTA, 10% Zn-EDTA while for Peperomia obtusifolia “Green Gold” is Z6, containing 4% Fe-EDTA, 4% Cu-EDTA, 4% Mn-EDTA, 4% Zn-EDTA. These findings offer valuable insights for enhancing the planting of variegated ornamental plants, benefiting the ornamental plant industry.
