An investigation was carried out to find out the effect of water soluble fertilizers on growth of orchid (Phalaenopsis Hybrid) cv. Shagan at BTCC, Orissa University of Agriculture and Technology, Bhubaneswar, Odisha during the period January 2016 to March 2017. The tissue cultured orchid plantlets were planted in pots containing potting mixture comprising of coal and coconut fibre, in equal proportion. Total population was ninety nine having eleven different treatments and each treatment contains 3 pots. The trial was conducted with ten treatments viz. T1 (NPK 0:0:50 @0.1%), T2 (NPK 0:0:50 @ 0.2%), T3 (NPK 0:52:34 @ 0.1%), T4 (NPK 0:52:34 @ 0.2%), T5 (NPK 13:0:45 @ 0.1%), T6 (NPK 13:0:45 @ 0.2%), T7 (NPK 19:19:19 @ 0.1%), T8 (NPK 19:19:19 @ 0.2%), T9 (NPK 20:20:20 @ 0.1%), T10 (NPK 20:20:20 @ 0.2%) and T11 (control). The experiment was laid out in Completely Randomized Design with three replications. Water soluble fertilizers were applied by dissolving in water. The study revealed that there was significant difference in vegetative and floral characters due to application of different grades of fertilizers at different concentrations. Among all treatments, T7 (NPK 19:19:19 @ 0.1%) recorded the maximum value for vegetative characters, like plant height (8.90 cm), number of leaves per plant (5.77), leaf length (19.83 cm), leaf breadth (5.83 cm) and leaf area (84.83 cm2); floral characters like number of spike per plant (2.0) and number of flowers per spike (10.00) as compared to other treatments. It is therefore suggested that for getting better quality plant, treatment T7 (NPK 19:19:19 @ 0.1%) is recommended under Bhubaneswar condition in Phalaenopsis cv. Shagan.
