Abstract:
There is no possibility of creating a permanent and sustainable society without vertical gardening. It can be installed in any part of the world by using plant species suitable for that particular area. As there is lack of horizontal expansion, the only space left is vertical. Hence, the only solution to live with greenery in cities is creating green vertical walls. Current investigation was conducted to study the effect of different concentrations of nutrient formulations on total plant fresh and dry biomass as well as leaf nutrient accumulation in eight indoor plant species namely Aglaonema angustifolium, Dracaena compacta (Red), Dracaena godseffiana, Scindapsis aureus, Schefflera arboricola variegata, Syngonium podophyllum, Philodendron selloum and Schefflera arboricola. These plants were grown using five nutrient formulations which included four concentrations of Hoagland’s nutrient solution (25%, 50%, 75% and 100% of Hoagland’s solution) and fifth was self-composed nutrient concentration. Experimental design was factorial completely randomized block keeping three replications in each treatment. The nutrient formulation of 100% of the Hoagland’s solution (NF IV) proved to be the best in terms of the growth and nutrient accumulation. Best five species evaluated based on performance of various parameters studied were Schefflera arboricola, Dracaena godseffiana, Philodendron selloum, Syngonium podophyllum and Scindapsis aureus.
