Effect of Integrated Nutrient Management on Growth and Flowering of Gerbera (Gerbera jamasonii L.) Var. Rosalin under Naturally Ventilated Polyhouse Condition

An investigation was carried at Department of Floriculture and Landscape Architecture, Kittur Rani Channamma College of Horticulture, Arabhavi, Gokak taluk and Belgaum district, to study the effect of INM practices in improving the growth and yield of gerbera ( Gerbera jamasonii L.) Var. Rosalin. The experiment was conducted with six kinds of organic substrates along with inorganic fertilizers. The treatment combination of T 1 (RDF + FYM) viz., plant height (92.6), number of leaves per plant (171.30) and leaf area per plant (1062.06 cm 2 ) were found to be maximum at 90 DAP. 75% RDF+ Glomus fasciculatum + Trichoderma harzianum + Panchagavya +Amrut pani + Dry mulch + Agnihothra ash favorably influenced flower parameters like minimum number of days taken for 50 per cent flowering (139.87 days), maximum stalk length (75.45 cm), flower diameter (7.15 cm), number of flowers per plant (19.03) and flower yield per m 2 (634.27) were found to be highest. The results proved that 75% RDF+ Glomus fasciculatum + Trichoderma harzianum + Panchagavya +Amrut pani + Dry mulch + Agnihothra ash improved the growth and flowering attributes in gerbera.
