Supply of mineral nutrients in adequate amount is one of the most important factors that control growth and development of flower crops. The present experiment was conducted in the Horticulture Experimental farm, Assam Agricultural University, Jorhat, Assam during the year 2014-15 and 2015-16 using completely randomized design with thirteen numbers of treatments and three replications. The orchids were grown in coconut husk under 50 per cent shade net house in partially controlled atmosphere. The analysis revealed that foliar application of T12( RDF+ Ca 750ppm) was proved to be superior in length of pesudobulb (28.72 cm), Number of leaves (6.50), leaf area (87.23cm2), Number of spike per plant (2.17), Number of florets per spike (5.99), Size of flower (8.5 cm) and T11 recorded maximum in plant height (71.67 cm), Number of pseudobulbs (9.0), length of spike (39.0 cm), girth of spike (1.10 cm), T10 recorded maximum in colour FBV to colour showing (39.10 days), showing to full bloom (8.50 days), first floret open to full bloom(6.16 days). Self life and vase life were observed maximum in T2 (RDF+ Zn 500ppm; 48.99, 41.99 days).
