The present investigation “Standardization of nano urea and composition of potting media on growth and quality of Philodendron scandens” was carried out at College of Horticulture, Mojerla, SKLTSHU, during December 2021 to May 2022. The experiment was laid out in FRBD with two factors in which first factor consists of six levels of nano urea viz., N0: No spray of nano urea, N₁: Conventional urea 2 g L^-1, N₂: Nano urea 0.5 ml L^-1, N₃: Nano urea 1 ml L^-1, N₄: Nano urea 1.5 ml L^-1, N₅: Nano urea 2 ml L^-1 and second factor consists of four levels of composition of potting media viz., M₁: Red earth, M₂: Red earth + Cocopeat (1:1), M₃: Red earth + Cocopeat + FYM (1:1:1), M₄: Red earth + Cocopeat + FYM (2:1:1). Among the nano urea levels, Nano urea, 2 ml L^-1 (N₅) recorded maximum values for plant height (24.22, 31.64 and 38.98 cm), number of leaves (12.63, 27.26 and 52.23), leaf width (10.118 cm at 125 DAP), leaf area (105.73, 142.73 and 169.25 cm²) and LAI (0.92, 2.12 and 6.05), while conventional urea 2 g L^-1 (N₁) recorded maximum values (239.77, 257.91 and 266.051 cm² g^-1) and nano urea 5 ml L^-1 (N₅) recorded minimum values (183.37, 196.34 and 197.24 cm² g^-1) for SLA. With respect to potting media composition, Red Earth + Cocopeat + FYM (1:1:1) (M₃) recorded the maximum values for plant height (24.18, 30.38 and 36.12 cm), number of leaves (11.84, 23.5 and 48.45), leaf width (10.19 cm at 125 DAP), leaf area (109.93, 143.71 and 167.08 cm²), LAI (1.3, 3.62 and 10.52) and for SLA (237.625, 247.475 and 247.854 cm² g^-1) at 65, 95 and 125 days after planting. These results revealed that significant effect on the Plant height, number of leaves, leaf length, leaf width, leaf area and LAI registered with the treatment combination of nano urea (2.0 ml L^-1) and Red Earth + Cocopeat + FYM in the ratio (1:1:1).
