Effect of Micronutrients on Growth and Yield of Chrysanthemum (Dendrathemum grandiflorum Tzeuleu) cv.CO 1

Abstract

Micronutrient is considered as one of the constraints in the optimum production of crops. A field experiment entitled “Effect of micronutrients on growth, yield and quality of chrysanthemum (Dendrathemum grandiflorum Tzeuleu) cv.CO 1” was carried out at Faculty of Agriculture, Annamalai University, during 2008-2010 in Randomized Block Design with seventeen treatments and three replications. The treatment comprised of various combination of micronutrients viz., Zinc sulphate 0.5 %, Ferrous sulphate 0.5 %, Borax 0.5 %, Manganese sulphate 0.5 %, Copper sulphate 0.5 %, Mixture of all micronutrients 0.5 % and micronutrients mixture at 12.5 kg ha-1, different concentrations with recommended 25 t FYM ha-1 + Recommended Dose of Fertilizer (RDF) and a control at 5 different interval. The results of present investigation indicated that, the vegetative growth in term of plant height (54.62 cm), number of branches (10.23), number of leaves (52.15), stem girth (3.33 cm) and flower yield per plant (201.74 g) were found superior under, soil application of micronutrients mixture @ 12.5 kg ha-1 in split as basal, 25, 50 and 75 DAT days after transplanting (T17).
