An experiment entitled “Effect of growing media on growth and performance of pothos (Scindapsus aureus L.) under modular biowall system” was carried out at Department of Floriculture and Landscape Architecture, ASPEE College of Horticulture, Navsari Agricultural University, Navsari, Gujarat. during the year 2023-24. The experiment was conducted by using eight treatments of media combinations with four repetitions viz., M₁-garden soil: perlite: vermicompost (2:1:1 v/v); M₂-garden soil: vermiculite: vermicompost (2:1:1 v/v); M₃-cocopeat: perlite: vermicompost (2:1:1 v/v); M₄-cocopeat: vermiculite: vermicompost (2:1:1 v/v); M₅-peatmoss: perlite: vermicompost (2:1:1 v/v); M₆-peatmoss: vermiculite: vermicompost 2:1:1 v/v); M₇-peatmoss: cocopeat: vermiculite: vermicompost (1:1:1:1 v/v); M₈-peatmoss: cocopeat: perlite: vermicompost (1:1:1:1 v/v). The data were analyzed by using Completely Randomized Design. Among all the media combinations, cocopeat: vermiculite: vermicompost @ 2:1:1 v/v promoted the maximum vine length (22.70 cm), number of leaves/plant (8.34), leaf area (27.64 cm²), leaf length (8.90 cm), leaf width (5.71 cm), number of roots (12.00), fresh and dry weight of roots (6.60 g and 0.47 g, respectively), fresh and dry weight of shoots (13.74 g and 1.14 g, respectively) as well as root: shoot ratio (0.42). Whereas, the effect of growing media on number of shoots/plant was found non-significant. Similarly, quality parameters viz., visual quality grade (7.87 out of 10) and total chlorophyll content at the end of the experiment (0.466 mg/g) were also recorded the highest by the plants grown in cocopeat: vermiculite: vermicompost @ 2:1:1 v/v. Furthermore, the media analysis revealed that the lowest pH (6.19 and 6.34, respectively), EC (0.32 dS/m and 0.44 dS/m, respectively) and bulk density (0.58 g/cm³ and 0.59 g/cm³, respectively) before and after the end of the experiment were observed in the media combination of peatmoss: vermiculite: vermicompost @ 2:1:1 v/v. The media combination of cocopeat: vermiculite: vermicompost @ 2:1:1 v/v also recorded the highest water holding capacity before as well as after the end of the experiment (68.75% and 68.54%, respectively), which proved it the best media combination for pothos under modular biowall system.
