Abstract:
A study was conducted to evaluate the effect of plant density on growth, flowering corm and cormel production of gladiolus (Gladiolus sp.) cv. American Beauty at the farm of the Department of Horticulture, C.C.R (P.G.) College, Muzaffarnagar (Uttar Pradesh). The experiment was laid out in randomized complete block design with four replications and three spacing’s viz. S1 (40cm x 20cm), S2 (30cm x 40cm) and S3 (40cm x 40cm). The observations were recorded for various vegetative, floral and corm parameters. Maximum germination percentage (86.71%), plant height (105.66cm) and number of leaves per plant (8.01), number of days taken for initiation of spike (94.13 days), number of spikes per plant (0.96), length of spike (81.56cm ), number of florets per spike (17.86) and duration of flowering (18.54 days) was found with 30cm x 40cm spacing (S2). However, number of corms per plant (1.31), number of cormels per plant (21.56), weight of corms per plant (57.68g), weight of cormels per plant (36.43g) was found maximum with 40cm x 40cm spacing (S3) which was at par with S2, whereas, yield of corms and cormels per plot (3.18) was found maximum with 40cm x 20cm spacing (S1). Hence, 30cm x 40cm spacing can be recommended for the commercial cultivation of gladiolus.
