Abstract: Experiment was carried out to study influence of different levels of nitrogen, potassium and their combination in form of foliar spray on dendrobium plants grown in a naturally ventilated polyhouse at floriculture farm of ASPEE College of Horticulture and Forestry for two years (2014-15 and 2015-16). The study was carried out in a completely randomized design with nine treatments T1 (10% N & 10% K), T2 (10% N & 20% K), T3 (10% N & 30% K), T4 (20% N & 10% K), T5 (20% N & 20% K), T6 (20% N & 30% K), T7 (30% N & 10% K), T8 (30% N & 20% K), T9 (30% N & 30% K). Treatments were given in a form of foliar spray once every week and 0.2 % solution of above treatments was used for spraying. Significantly maximum height of plant, number of leaves, leaf area and number of shoots were produced by application of treatment T9 (30% N & 30% K). Flowering characters viz. inflorescence length, rachis length, number of inflorescence, number of florets and post harvest life of inflorescence were also found significantly highest with treatment T9 (30% N & 30% K). However for most of the characters other treatments like T8, T7, T6, T5, T4 and T3 were at par with treatment T9. Hence statistically T3 (10% nitrogen + 30% potassium) can be considered as best among all treatments from economic view point.
