A pot culture experiment was conducted in botanical garden of Mount Carmel College, Bengaluru, India, to study the effect of Trichoderma and in combination with other biofertlizers and on morphological parameters and NPK content of Kaempferiagalanga and Costusigneus. The results showed that mixture of rhizobacteria along with Trichoderma showed better result. NPK content also increased in the plants inoculated with mixture of biofertilizers compared to Trichoderma alone. All growth parameters like plant height, number of leaves and biomass showed better result in the mixture inoculated plants. Application of the Trichoderma alone or in combination exhibited in general a considerable improvement in above bio nutrient parameters as compared to their respective control. Kaempferia galanga was better compared to Costusigneus in growth as well as in NPK content.
