A pot experiment was conducted during 2001 and 2002 seas0₁s to
explore the response of Chrysanthemum morifolium plants to N·min ral-
and/or bio-fertillzer treatments, as well as, Fe and Zn concentrations. Both ammonium sulphate (9.6 g/pot or ammonium sulphate 4.8 g[pot
+ nitrobeln) effectively increased different vegetative growth characters,
promoted flowering parameters and stimulated various chemical constituents
such as N, Fe and Zn % and carbohydrates and chlorophylls contents in the
leaves. Similarly, Fe or Zn gave rise to most pre-mentioned vegetative
growth, flowering and chemical constituents. In general, the combined
treatment consisting of ~ dose ammonium sulphate (4.8 g/pot) + nitrobein
plus Fe at 80 ppm or Zn at 50 ppm gave reasonable vegetative growth bnd
best quality and quantity of flower production.
