Anthurium is the latest sensation of Indian floriculture scene and the genus Anthurium, with 700 species is largest genus of the family Araceae. Anthurium is an important tropical ornamental plant grown for its colourful spathe & attractive foliage. The study was plotted according to a Completely Randomized Design (CRD) with Duncan’s Multiple Range Test (DMRT). The experiment was conducted during the year 2018-2019 and 2021-2022 throughout the year under agroshadenet structure of RKVY Project on Anthurium, Department of Floriculture and Landscaping, Biotechnology-cum-Tissue Culture Centre, Orissa University of Agriculture and Technology (OUAT), Odisha. It has been concluded that the vegetative parameters of Anthurium andraeanum cv. Xavia, treatment T7 (ZnONPs@75ppm) significantly enhanced the Plant height (43.43 cm), Plant spread (46.13 cm), No. of suckers (3.56 nos.) and leaf petiole length (34.06 cm) in compare to other treatments.

Leaf Petiole length, Plant spread, Plant height and number of suckers

The Anthurium andraeanum cv. Xavia was significantly influenced on vegetative characteristics by application of various micro nutrients and nano particles. It is concluded that among various treatment, maximum plant height (43.43 cm), plant spread (46.13), no. of suckers (3.56 nos.) & leaf petiole length (34.6 cm.) was observed with i.e. Application of ZnO NPs @ 75 ppm. Whereas minimum plant height (33.28 cm), plant spread (39.08 cm), no. of suckers (1.28 nos.) & leaf petiole length (29.62 cm.) was recorded in T1 (Control). From the present investigation it is concluded that among 11 treatments foliar application of Zinc Oxide nanoparticles (ZnONPs) @ 75ppm was considered to be best for the Anthurium andraeanum cultivars Xavia in all aspects like vegetative parameters, Floral characteristics as well as postharvest life. The use of micronutrients and micronutrient-based nanoparticles in the plants reduces the dependency on chemical fertilizers, thereby, improving the soil health in addition to the producing a good crop.
