A biofertilizer is a biological material that
contains active or dormant microbe cells (bacteria,
actinomycetes, fungi, algae) that help fix atmospheric N or
solubilize/mobilize soil nutrients while also secreting
growth-promoting chemicals to boost growth and yield.
This paper reviews research and development regarding
bio-fertilizers in Nepal. The usage of biofertilizers can be
very beneficial for maintaining the agricultural systems. A
number of research groups and organizations have been
working on biofertilizer research and development to
improve the usage of biofertilizers in Nepal's agriculture.
In Nepal, Azotobacter and Rhizobium strains are used in
the production of bio-fertilizers. However, there have been
fewer attempts to identify and classify associative N fixers.
If Nepal works more on N fixers along with standard
production of biofertilizers, it would help in the increment
of agricultural yield by improving soil quality.
