Micronutrients Affects Vegetative Growth and Flowering Parameters of Chrysanthemum (Chrysanthemum morifolium)

Abstract

The present investigation was carried out at Research cum Horticultural Farm in Indira Gandhi Krishi Vishwavidyalaya, Raipur during the year 2021–22. There were ten separate micronutrients treatments consisting of different concentrations of viz., T1 control (RDF), T2 (FeSO4@0.2%), T3 (FeSO4@0.4%), T4 (FeSO4@0.6%), T5 (ZnSO4@0.2%), T6 (ZnSO4@0.4%), T7 (ZnSO4@0.6%), T8 (Borax@0.2%), T9 (Borax@ 0.4%), T10 (Borax @0.6%) were applied. The recommended dose of fertilizers viz., 150 kg N,100 kg P2O5 and 80 kg K2O/ha was given as basal dose at the time of field preparation. Observations were made on vegetative growth, flowering and yield parameters of chrysanthemum. The result indicated that the treatment T6 [ZnSO4(0.4%)] performed better in the observations recorded on growth parametersviz.,plant height (18.30cm and 27.88cm) at 30 and 50 DAP (days after planting) respectively, plant spread(E-W) (13.59cm and 26.80cm) at 30 and 50 DAP respectively, plant spread(N-S) (12.82cm and 26.60cm) at 30 and 50 DAP respectively. Number of primary branches per plant was 5.77. Similarly, in flowering attributes treatment T6 [ZnSO4(0.4%)] showed best result viz., days taken for flower bud initiation (49.09d), days taken to flower opening(60.58d), number of flower per plant (29.05), diameter of flower(4.78cm) and weight of flower per plant (2.05g).
