Effect of different plant spacing and planting depth on growth and flower yield of Gladiolus (Gladiolus grandiflorus L.)

Abstract

The present experiment was carried out during August, 2017 to December, 2017 in Departmental Research Field of Department of Horticulture, SHUATS, Allahabad. The experiment was conducted in Randomized Block Design (RBD), four spacing i.e. 20x25 cm, 25x25cm, 30x40 cm and 40x40 cm and four planting depth i.e. 4 cm, 6 cm, 8 cm and 10 cm are used for Gladiolus Planting, the total number of treatments were sixteen, each treatment replicated thrice. From the present investigation on different spacing and planting depth of Gladiolus, it is found that the treatment T7 (Spacing 25x25 cm + Depth 8 cm) was found to be the best in terms of growth and flower yield parameters, followed by treatment T4 (Spacing 20x25 cm + Depth 10 cm) and the Vase life of flower was recorded maximum in treatment T3 (Spacing 20x25 cm + Depth 8 cm), and the minimum growth and flower yield was recorded in treatment T16 (Spacing 40x40 cm + Depth 10 cm).
