Efficacy of biostimulants on physiology of chrysanthemum (dendranthema grandiflora tzvelev.) cv. kolar local under naturally ventilated polyhouse

Studies on efficacy of biostimulants on physiology of chrysanthemum under naturally ventilated polyhouse were carried out at department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere during 2015-16. Rooted terminal cuttings of chrysanthem cv. Kolar Local were taken for the study. 12 biostimulant formulations in 2 different concentrations were taken as a foliar spray at 60, 90 and 120 days after planting along with RDF. The treatment receiving only RDF was taken as control. The results revealed that among the biostimulants treatment receiving Biovita (Brown sea weed extract) @ 0.5 per cent proved the best as compared to other treatments.
