Abstract
The present investigation was carried out at the Garden Section, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar (Uttarakhand) during2011-12 to2012-13to find out suitabledoses of fertilizer (N, P2O5 and K2O) for vegetative, floraland leaf nutrient parameter of Bird-of-
Paradise plant grown under open conditions. For the experiment, three fertilizers (N, P2O5 and K2O) were used with three different levelsviz.,nitrogen 25 g (N1), 50 g (N2) and 75 g (N3) as N,level of phosphorus 10 g (P1), 15 g (P2) and 20 g (P3) as P2O5and level of potassium 25 g (K1), 50 g (K2) and 75 g (K3) as K2O. Total number of treatment combinations were twenty eight with three replication and four plants were taken in each replication. Experimental design wasRandomized Block Design (RBD). Among Twenty eight treatment combinations, treatment T25 (75 g N, 20 g P2O5 and 25 g K2O/ m2)was found to be the best treatment for most of the parameters viz., maximum plant height, leaf blade length, leaf blade breadth, leaf stalk length,
number of leaves per plant, plant spread, flower spike length, vase life of flowers.Treatment T0 (without the application of any fertilizers) was found inferior in almost all aspects of the vegetative as well as floral attributes during the present investigation.
