Technical Bulletin : Biofertilizer Technology for Vegetable crops KAU Vellani
Not AvailableEfficient N, P and K biofertilizer
microorganisms were isolated
from Kerala soils. The
compatibility of these N, P and K
biofertilizer microorganisms were
studied and the most compatible
organisms were selected. They
include two nitrogen fixers
(Azotobacter chroococcum,
Azospirillum lipoferum), a
phosphate solubilizing bacterium
(Bacillus megaterium) and a
potassium solubilizing bacterium
(Bacillus sporothermodurans).
In order to reduce the cost of
production, a new medium (PGPR
medium) was developed for the
mass multiplication of these
microorganisms. The technology
for mass multiplication was
standardized. Currently talc-based
formulation of PGPR Mix β I is
being produced for distribution to
farmers throughout Kerala. When
single inoculant biofertilizer
technology give yield increase
of 10 percent, PGPR Mix β I is
found to give yield increase of
20 - 25 percent depending on
the crop.Not Availabl
