EFFECT OF CULTIVAR AND SOWING DEPTH ON GROWTH AND YIELD OF SUMMER GLADIOLUS

Abstract

The experiment was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from April to October 2015. The experiment consisted of two factors. Factor A: three types of sowing depth: D 28 1= 4cm; D = 12cm and Factor B: three types of cultivar: V 1 = White;V 2 = Yellow;V = Pink gladiolus, respectively. The experiment was laid out in Randomized Complete Block Design with three replications. Depth of sowing and different cultivars showed significant variance on most of the parameters. In case of sowing depth, the highest yield of spike 2 3 and the lowest yield of spike . For cultivar, the highest yield of spike 3 and lowest yield of spike 3 1 . For combined effect, the highest yield of spike 2 V and the lowest spike 1 V 3 1 . The highest benefit cost ratio and lowest 3 V . So, sowing of white cultivar in 8 cm depth was found best for growth, flowering and yield of gladiolus.
