A field experiment was carried out during the two successive seasons of 2016/2017 and 2017/2018. The aim of this study was to investigate the effect of farmyard manure (FYM) at four levels (0, 10, 15 and 20 m3/fed) in combination with Minia Azotein (M.A.) at 50 ml/plant and/or some vitamins (E and C) each at 50 ppm, in addition to the control on vegetative growth and flowering of Gladiolus grandiflorus var. Gold Field plants. Results showed that leaf length (cm), number of leaves/plant, leaves dry weight/plant (g), length of spike (cm), spike diameter (mm), spike fresh weight (g), number of florets/spike, lower floret diameter (cm) and lower floret fresh weight (g) were gradually increased by increasing the levels of farmyard manure with significant differences were detected between successive treatments. Also, Minia Azotein (M.A.) and/or some vitamins (E and C) treatments significantly increased all vegetative growth and flowering parameters in comparison with the control. Minia Azotein (M.A.) plus vitamins E and vitamin C were more effective in this concern. It was found also that the use of FYM (20 m3/fed) in combination with Minia Azotein (M.A.) plus vit. E and vit. C followed by 20 m3/fed FYM with M.A. + vit. C then 15 m3/fed FYM with M.A. + vit. E + vit. C noticeably improved the different vegetative growth and flowering parameters of gladiolus plants.
