Effect of Land Configuration and Planting Depth on Corm and Cormel Production of Gladiolus (Gladiolus spp.)

Abstract

The present experiment was carried out at department of Floriculture and Landscape Architecture, College of Horticulture, Junagadh Agricultural University, Junagadh (Gujarat) during the years 2021-22 and 2022-23 with randomized block design (Factorial) having three replications. The treatment combinations consisting three land configuration methods (L1- Flat bed, L2- Raised bed with 2 rows and L3- Ridge and furrow) and two planting depth (D1- 3.5 cm and D2- 5.5 cm). The results indicated that maximum number of corms (1.58), number of cormels (26.98), diameter of corms (63.77 mm), diameter of cormels (3.16 mm), weight of corms (64.13 g) and weight of cormels (22.11 g) were recorded with raised bed with 2 rows (L2). The variation due to planting depth was also found significant for all the parameters and maximum number of corms (1.46), number of cormels (25.52), diameter of corms (56.43 mm), diameter of cormels (3.09 mm), weight of corms (56.02 g) and weight of cormels (21.78 g) were obtained with planting at 3.5 cm depth (D1). Raised bed planting had favourable effects on growth and flowering of gladiolus as compared to ridge and furrow and flat bed planting.
