Effect of Micronutrients on Flowering and Yield Attributes of Chrysanthemum (Dendrathemum grandiflora Tzeuleu) cv.CO 1

Abstract

Micronutrients are essential for crop growth and are equally important as primary and secondary nutrients. The Present study was carried out at orchard, Department of Horticulture Faculty of Agriculture, in the year 2010. The experiment was laid out in a Randomised 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, two different concentrations with recommended dose 25 t FYM ha-1 + RDF of N, P, K and a control at 5 different interval on flowering and yield attributes of chrysanthemum. The results revealed that soil application of micronutrients mixture @ 12.5 kg ha-1 in split as basal, 25, 50 and 75 DAT were found superior on number of flowers per plant (89.91), flower stalk length (8.92 cm) and flower yield per hectare (21.14 t ha-1).
