Experiment was carried out to study the 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) +Water], T2 [(10% N + 10% K) + Vermiwash], T3 [(10% N + 10% K) + Cow urine], T4 [(20% N + 20% K) + Water], T5 [(20% N + 20% K) + Vermiwash], T6 [(20% N + 20% K) + Cow urine], T7 [(30% N + 30% K) + Water], T8 [(30% N + 30% K) + Vermiwash] and T9 [(30% N + 30% K) + Cow urine]. Inorganic fertilizers i.e. nitrogen and potassium were given in form of foliar spray once every week in a concentration of 0.2 %, while, organic fertilizers such as vermiwash and cow urine were sprayed in a concentration of 2 % once every fortnight. 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) + Cow urine]. 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) + Cow urine]. However, for most of the characters T8 was at par with treatment T9.
