Abstract


An investigation was carried out to study the effect of organic and inorganic fertilizers on sprouting, growth, flowering and nutrient status in heliconia (Heliconia sp.) cv. Golden Torch under protected cultivation at department of Floriculture and Landscape Architecture, Kittur Rani Chennamma College of Horticulture, Arabhavi during 2008-2009. The treatments consisted of different combinations of organic and inorganic fertilizers which were tested in randomized block design with three replications. The treatment T5 with Glomus fasciculatum, Trichoderma harzianum and other bioformulations viz., Panchagavya, Amrit pani, Agnihothra ash, dry mulch and 2 kg FYM/ m2 recorded significantly less number of days for initiation of sprouting (60.67), 50 per cent sprouting (76.30), flower bud formation (208 days) and first flowering (217 days). The complete sprouting (92 days) and high sprouting percentage (94.45 %) were recorded in T1 treatment (Glomus fasciculatum + Trichoderma harzianum) which was statistically at par with T5. The treatment T10 (25:10:20 g NPK + 2 kg FYM/ m2), T5 and T11 (25:10:20 g NPK+ vermicompost 2 t/ ha) were statistically at par for different parameters like plant height, number of tillers and number of flower per plant. Whereas maximum chlorophyll 'a' (0.722 mg/ g),'b'(0.373 mg/ g) and total chlorophyll (1.095 mg/ g), flowers yield per plant (3.07), flower yield per meter square (64.73 flowers), higher content of nitrogen (133.73 kg/ ha), phosphorus (35.84 kg/ ha) and potassium (284.78 kg/ ha) in soil and nitrogen (1.72 %), phosphorus (0.37 %) and potassium (3.09 %) in leaves were recorded maximum in T10 followed by T11 and T5.
