Effect of nitrogen and hormones on growth and development of Dendrobium Cv. Sonia -17

Abstract

                                An experiment to study the effect of graded doses of nitrogen with constant dose of P and K (10:10:10, 20:10:10 and 30:10:10) at two concentrations (0.1% and 0.2%) along with three growth regulators at two concentrations each of BA 100 and 200 ppm, GA, 100 and 200 ppm and IAA 250 and 500 ppm on growth and development of orchid Dendrobium Cv. Sonia 17 was conducted in green house. The treatment combination, NPK 30:10:10 at 0.2% concentration+ BA 200 ppm resulted in progressive growth of plants. Improvement in vegetative growth was observed through increase in the height of plant, higher number of pseudobulbs and higher number of leaves per plant.

Key words : Hormones, Growth regulators
