| dc.description.abstract | The present investigations entitled “Optimization of protocol for indoor vertical garden using different nutrient formulations and light intensities” were undertaken at Landscape Nursery, Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana, during 2017-19. The study consisted of two experiments, the first experiment was initiated to evaluate indoor ornamental plants and determine the optimum nutrient formulations for successful installation of an indoor vertical garden. For this, fifteen indoor ornamental plant species were selected and grown in soilless media consisting of cocopeat, perlite and vermiculite in the ratio 3:1:1 with four concentrations of Hoagland nutrient solution (25 % (NF I), 50 % (NF II), 75 % (NF III) and 100 % (NF IV) of Hoagland‟s solution). The fifth treatment (NF V) included self-composed nutrient formulation (Azeezahmed 2014). The plant species were evaluated on the basis of various growth parameters (survival percentage, plant height, number of leaves, leaf length, leaf thickness, internodal length, plant spread, leaf area, fresh and dry plant biomass, root density, maximum shoot and root length), physiological parameters (leaf chlorophyll content, leaf carotenoid content, relative leaf water content), biochemical parameters (proline content) and plant leaf nutrient analysis (N, P, K, Ca, Mg, S). Experimental design was Factorial Completely Randomized Design keeping three replications in each treatment. NF IV (100 % of the Hoagland‟s solution) was significantly better compared with other treatments in terms of growth, physiological, biochemical characters and nutrient accumulation of the plants under indoor conditions. Best five species screened on the basis of performance of various parameters studied were Schefflera arboricola, Dracaena godseffiana, Philodendron salloum, Syngonium podophyllum and Scindapsis aureus. The results of the first year experiment were further used in the second experiment in which the best nutrient formulation along with the selected plant species were used in the indoor vertical garden under different light intensities. The screened indoor plants were planted in the pots filled with media containing cocopeat : perlite : vermiculite in the ratio 3:1:1 arranged as vertical structures (611” x 43”) aligned to the walls of the interiors of a room. Four such structures were fabricated. Each frame was artificially illuminated with different light intensities i.e. the first frame with the light intensity ranging between 700-1100 lux, second 1100-1500 lux, the third frame 1500-1900 lux and the fourth frame was control with 150-250 lux (no artificial light illumination). These light intensities were PWM controlled. The plant species were evaluated on the basis of their response towards different light intensities w.r.t. growth, physiological, biochemical and plant leaf nutrient parameters. From the most effective positive response in terms of various parameters under study, it can be concluded that Philodendron salloum responded best to LI I (700-1100 lux), Scindapsis aureus and Dracaena godseffiana to LI II (1100-1500 lux) and Schefflera arboricola and Syngonium podophyllum to LI III (1500-1900 lux). | en_US |
