Abstract:
Food insecurity is an emerging concern in the world, as global populations are increasing
and the yield and quality of crops are declining. Excessive use of agrochemicals designed to
improve plant growth is very damaging to the environment, which warrants the need for
sustainable alternatives. The exploitation of plant growth-promoting bacteria is one alternative
being considered due to the inherent relationship between plants and beneficial bacteria within
the soil. The use of biochar provides its own benefits to plants in addition to acting as a carrier
for bacterial inoculum.
Here we investigated the effects that a formulation of Fictibacillus enclensis and biochar had on the vegetative growth of collard greens, carrots, and barley. Carrots treated with the F.
enclensis and biochar formulation exhibited little benefit in terms of carrot root weight and
length; however, collard greens treated with the F. enclensis and biochar formulation displayed
improvements in leaf weight. In the barley trial, the formulation of F. enclensis and biochar did
improve some aspects of the vegetative growth of barley when compared to F. enclensis by
itself.
However, these results can not be relied upon. The positive controls did not produce any
benefits to the vegetative growth of the plants. Therefore, any results that are obtained do not
accurately showcase the effects that the F. enclensis and biochar formulation has on the
vegetative growth of plants; something is wrong in the system being used to grow the plants. The
growth of the plants is being restricted by certain limiting resources/factors. Consequently, any
interpretation of the results is deemed inaccurate and unreliable.
