The experiment was carried out in two consecutive years 2009 and 2010 at Regional Research Station (Hill zone) of Uttar Banga Krishi Viswavidyalaya, Kalimpong, Darjeeling, West Bengal to study the effect of organic resources of nutrients for corms and cormlet production of three cultivars of gladiolus (Gladiolus sp.) namely Candyman, American Beauty and Jester. The different organic sources of nutrients namely bone meal (5t/ha), Farm yard manure (FYM) (50t/ha), vermicompost (5t/ha) were used alone and in combination with bio-fertilizers namely [VAM] (2g/plant), Phosphobacteria (2g/plant) and Azospirillum (2g/plant). The cv. Jester performed better in production of number of corm per plant (2.28), equatorial diameter of corm (6.54 cm), average weight of corm (62.94 g) and average weight of cormlet (38.41 g). The higher polar diameter of corm (3.79 cm) and greater number of cormlet per plant (125.01) were produced by the cv. Candyman. Among the different treatments of manures and bio-fertilizers the application of FYM (25t/ha), vermicompost (2.5t/ha), bone meal (5t/ha) and Trichoderma @ 20g/m2 (T4) produced greater number of corm per plant (3.07), equatorial diameter of corms (6.42cm) and number of cormlet per plant (123.83). On the other hand, the treatment consisting of bone meal @ 5t/ha, VAM, Phosphobacteria and Azospirillum each @ 2g/plants and Trichoderma @ 20g/m2 in T9 was found better in respect of polar diameter of corm (3.90 cm) and average weight of corm (65.0 g). Among the combination of treatments, the propagation co-efficient was found maximum with the cv. Jester (495.60%) in the case of T9 (VAM @ 2g/plant + Phosphobacteria @ 2g/plant + Azospirillum @ 2g/plant + Bone meal @ 5t/ha + Trichoderma @ 20g/m2).
