Biofertilizers offers an alternative solution for such agrochemicals, and show yield increase of up to about 10–40% by increasing protein contents, essential amino acids, and vitamins, and by nitrogen fixation. [20] Since a bio-fertilizer is technically living, it can symbiotically associate with plant roots. Involved microorganisms could ...
