Effect of nano NPK and bio fertilizers on growth and flowering of potted zinnia (Zinnia elegans Jacq)

An experimental study entitled “Effect of Nano NPK and Bio fertilizers on growth and flowering of potted Zinnia – Zinnia elegans” was carried out during the rabi season of the year 2024 at PG research block, College of Horticulture, Rajendranagar, Sri Konda Laxman Telangana State Horticultural University. The experiment was laid out in Factorial Completely Block Design (FCRD) with three replications of two factors: Nano NPK and Bio fertilizers. The results revealed that N₁B₁-(Nano NPK 2 ml/L + 4 g/kg VAM ) maximum extend in plant height, stem diameter, number of nodes, number of branches, plant spread in both directions (East-West & North-South), in minimum reduced in number of branches per plant. N₁B₁-(Nano NPK 2 ml/L + 4 g/kg VAM) was found best for all vegetative growth parameter.
