Abstract:
Protected cultivation of flowers becomes less profitable with excessive use of fertilizers in commercial ventures. In the present experiment, the influence of microbial biofilm inoculants (Anabaena–Azotobacter, Anabaena–Trichoderma, and Trichoderma–Azotobacter) as field application and nursery treatment on the growth attributes in two varieties of chrysanthemum (var. White Star and Zembla) was studied. Varietal-specific responses in various growth attributes were recorded. All the growth attributes were highest in var. White Star. There are non-significant differences among biofilm treatments for all the attributes except for plant height in var. Zembla. Field application of biofilm and nursery treatment with Anabaena–Trichoderma and Trichoderma–Azotobacter showed a mixed response in both varieties. The Anabaena– Trichoderma and Trichoderma–Azotobacter biofilm inoculants proved superior in both chrysanthemum varieties.
