Influence of Inorganic and Organic Fertilizers on Growth and Yield of Dendrobium Orchid cv. Sonia 17

Abstract

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 T 1 [(10% N + 10% K) +Water], T 2 [(10% N + 10% K) + Vermiwash], T 3 [(10% N + 10% K) + Cow urine], T 4 [(20% N + 20% K) + Water], T 5 [(20% N + 20% K) + Vermiwash], T 6 [(20% N + 20% K) + Cow urine], T 7 [(30% N + 30% K) + Water], T 8 [(30% N + 30% K) + Vermiwash] and T 9 [(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 T 9 [(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 T 9 [(30% N + 30% K)

Effect of Foliar Spray of Polyamines and Biostimulants on Rose (Rosa hybrida L.) under Polyhouse Condition

“…Novel has been found to effectively influence good and qualitative production in different horticultural crops [11,12,13]. Cow urine has also been known to have presence of some growth promoting auxins [14] along with N, P, K, Ca, Mg, S and others [15] and influence plant growth in flower crops [16,17].…”
