The present investigation entitled “standardization of nutrients and growth promoters in Dendrobium Sonia ‘Earsakul’” was carried out at Floriculture Research Station, Thovalai, Kanyakumari district of Tamil Nadu during 2018. The experiment was laid out in a completely randomized design with 12 treatments and each treatment replicated thrice. The data recorded on various parameters viz., vegetative growth, flowering and were statistically analyzed. Significant differences were observed among nutrients and growth promoters on various vegetative growth parameters in Dendrobium Sonia ‘Earsakul’. Among all the treatments,T8- 20:10:10 NPK (0.5%) + GA3 - 100ppm + BA - 100ppmhas recorded significantly the highest plant height (48.12 cm), leaf length (13.88 cm), number of leaves per plant (8.67) and leaf breadth (4.01 cm). In flower traits, among all the treatments, T8- 20:10:10 NPK (0.5%) + GA3 - 100ppm + BA - 100ppmhas recorded significantly the maximum spike length (42 cm), flowers length (8.05 cm), flowers diameter (7.65 cm) and number of flowers per plant (7). Hence, the nutrients NPK (20:10:10) 0.5% and growth regulators GA3 (100 ppm) and (BA 100 ppm) can be applied to Dendrobium plants which are required to produce more number of flowers per plant and spike length.
