The aim of the present study was to determine the effect of different planting times and corm sizeson plant growth, development, and flower yield in Gladiolus. The Red Beauty variety was used as the studymaterial. In the study, two corm sizes (10–12 and 12–14 cm) and five different planting times (April 1,April 15, May 1, May 15, and June 1) were used. The sprouting time (day), flowering time (day), plantheight (cm), number of leaves (number/plant), length of the flower stem (cm), length of the spike (cm),number of florets (number/spike), thickness of the flower stem (mm), diameter of the new corm (cm),circumference of the new corm (cm), number of new corms (number/plant), weight of new corm (g/plant),number of cormels (number/plant) and weight (g/plant) and corm yield (g/plot) were determined. Wedetermined that the planting times indicated were suitable for cultivation under Sanliurfa conditions interms of yield and quality. The best Gladiolus cultivation times in Sanliurfa varied, but the best results wereobtained from large corms (12–14 cm). As the temperature increased, corm growth times increased, andplant height, number of leaves, new corm weight, and cormel number and weight decreased. The maximumflowering time and parcel yield were obtained from the fifth planting (June 1), the longest spikes, maximumnumber of florets, maximum number of cormels and greatest cormel weight, and greatest plant height weredetermined from the first and second planting times. There was no significant difference between plantingtimes for the other investigated parameters. The large corms (12–14 cm) were observed to be better thansmall corms (10–12 cm) for increases in most of the parameters investigated.
