Effect of different varieties and planting dates on the growth of gladiolus (Gladiolus grandiflorus) under Prayagraj condition

Abstract

An experiment on “effect of different planting dates on growth of different varieties of gladiolus (Gladiolus grandiflorus) under Prayagraj conditions” was conducted in Horticulture Research Field, Naini Agricultural Institute (NAI), SHUATS, Prayagraj during 2018-2019. The experiment was laid out in simple factorial randomized block design (FRBD) with three replications and seven varieties in four different months with a view to find out the overall growth of different varieties viz Ocilla, Flevo Spirit, White Prosperity, Extasy, Peter Pears, Charisma, Performer on different planting dates viz 20th October, 23rd November, 20th December 2018, 18th January 2019, on the basis of different growth parameters. Maximum plant height was found in variety ‘Charisma’ (101.63 cm) in October month (100.96 cm), Maximum number of leaves was found in variety ‘Ocilla’ (7.54) in October month (8.91), minimum number of days taken for spike emergence from planting was found in ‘Ocilla’ (68.78 days) in November month (66.21 days), maximum number of florets per plant was found in ‘Ocilla’ (13.85) in October month (14.18), minimum number of days taken for first floret opening was found in ‘Ocilla’ in October month (10.18 days), maximum floret diameter was observed in ‘Ocilla’ (8.25cm) in October month (9.77cm), maximum vase life of spike was found in ‘Ocilla’ (11.08 days) in October month (10.91 days) and maximum Benefit cost ratio was found in ‘Ocilla’ (3.79) in October month (2.18).
