Growth Responses Of Maize And Soybean To Application Of Rhizosphere Bacterial Consortium From Dry Land North Lombok

Abstract

This research aimed to study the growth responses of maize and soybean to the indigenous bacterial consortium application isolated from Lombok dryland farm. The study was tested in the sterile soil and nonsterile soil of growing media and with a different water capacity of growing media. The soil was taken from North Lombok dryland farm. Sterile soil was prepared by sterilization using an autoclave. The bacterial consortium was prepared by mixing 15 inoculums of rhizosphere bacteria isolated from Lombok dryland farm. The consortium inoculation by soil inoculation technique. The water capacity of growing media was set to 25%, 50%, and 75%. This research was done in the greenhouse scale. Growth parameters that analyzed were leaf number, leaf wide, leaf length, plant length, fresh weight of upper biomass, and dry weight of upper biomass. The results showed that plant growth is better in sterile soil compared to nonsterile soil. Plant growth is better also in the sterile soil inoculated with the bacterial consortium compared to nonsterile soil inoculated with the bacterial consortium. Plant growth was better in 75% and 50% than 25% water holding capacity of growing

The effect of antagonistic microbial and seed bulb-size on fusarium wilt and yield of shallot

“…This is because the consortium is not necessarily able to suppress the development of pathogens, microbial consortia are not able to compete with microbes that have colonized the roots first. The absence of early microbes will make it easier for the bacterial consortium to colonize the rhizosphere [13].…”

“…This resulted in the possibility that the growth-promoting microbial consortium was unable to compete with the microbes that had colonized the roots first. The absence of initial microbes will make it easier for the bacterial consortium to colonize the rhizosphere [13]. In this research, to see whether the pathogen is virulent or not, it can be seen from the amount of pathogens in the shallot after harvest.…”

“…This is influenced by biotic and abiotic environmental factors on the activity of biological agents. This is probably because differences in plant growth responses can be caused by the microbial status of the soil [13]. The results of the research related to Bacillus subtilis and Lysinibacillus sp.…”
