Effect of boron, calicum and zinc on gladiolus

The experiment conducted in the Department of Horticulture, C.S.A. University of Agriculture and Technology, Kanpur during 1998–99 on the gladiolus var. Sylvia at 3- leaf stage with borax, CaSO₄ and ZnSO₄ (0.2,0.5 and 0.75%) sprayings revealed that ZnSO₄ at 0.75% induced earlier flowering (75.81 days) and increased the number of corms (1,33). Length of leaf (55.75 cm) and length of floret (8.96 cm) were significantly increased with 0.2% borax + 0.75% ZnSO₄ and 0.5% CaSO₄ + 0.75% ZnSO₄, respectively. Spike length (78.50 cm), number of florets per spike (15.83), width of floret (8.51 cm), size of conn (6.44 cm) and weight of cormels (39.67 g) were found significantly increased under 0.2% borax + 0.5% CaSO₄. The corm weight (54.38g) was recorded maximum under 0.5% CaSO₄.
