Abstract

Dendrobium orchid cv. Singapore White is cultivated commercially for cut flower purpose. The performance of this orchid in response to the different nutrient concentrations was evaluated under the agro-climatic conditions of Kodagu during 2017-2020. Twelve nutrient doses were applied as foliar sprays at weekly intervals to study their effect on vegetative growth, flower production and quality parameters of the cut flowers. Plant height, number of leaves plant-1, leaf area, number of pseudobulbs plant-1, number of spikes plant-1 year-1, number of flowers spike-1 and spike length varied significantly with the nutrient doses. Foliar spray of 30:20:20 NPK 0.1% at weekly intervals recorded the maximum plant height of 53.21cm, number of spikes plant-1year-1 (10.01) with spike length of 44.43 cm and 16.20 flower spike-1.
