Purpose: One of the challenges of globalization to
developing countries is how to increase agricultural production that will take
care of the rapid increase in population. This can be achieved by the use of
plant growth promoting rhizobium (PGPR) which are various species of beneficial
microorganisms grown in the rhizosphere, participating in nutrient cycling and
the production of plant growth promoting substances.
Aim: The present study highlights the potential role of
plants growth promoting rhizobium species from organic base bio fertilizer
production from nitrogen fixing bacteria.
Methodology: Soil samples were collected from 12 sites, four
from each of the study areas viz; NARICT farm land, Yankusa Land fill, and
Sakadadi agricultural farm land. The total chromium content was analyzed using
atomic absorption spectrophotometry (AAS). Physiochemical analysis of the
contaminated and control landfills were also determined. The parameters
determined were color, odor, pH, temperature, Nitrogen, % potassium and %
phosphorus etc.
Results: All parameters were found to be higher than the WHO
limit except % Nitrogen, % Potassium and % Phosphorus that falls beyond.
Further investigations were carried out to checkmate the proximate analysis of
some nutritional values of Chemical fertilizer A and B as control while C for
biofertilizer (treated) Most of the results computed shows there were
significantly higher values in both macronutrient and micronutrient in
Biofertilizer(C) production than those of the Chemical fertilizer (A and B). In
view of the current investigation, bacteria isolate like those of (Rhizobium
sp.) namely; Rhizobium japonicum, Rhizobium lupine etc., were isolated as
nitrogen fixing bacteria from root nodules of soya bean. Thus identification,
and characterization rhizobia sp. for the production of biofertilizer in
selective modified (MYEMA) through which propagation of bacteria mass cells
were accentuated in-situ: To this effect, the propagated mass cells of the
bacteria were therefore meticulously and circumspectly mixed with multiple
carrier base materials; for further utilization in the soils to increase its
nutrient quality naturally after combining it with the soil. For nitrogen is
one of the important components which acts as a building blocks of most
biomolecules, but this inert nitrogen cannot be utilized by plants so the
Rhizobium bacteria helps to fix the atmospheric nitrogen to ammonia which can
be utilized by plants.
Novelty: In view of this study the production of biofertilizer
from nitrogen fixing bacterial strains as well as utilizing them in the organic
farming is a well come development that would protect and sub guide both
develop and developing countries from decay as well as maintaining
self-reliance (prestige)( no more Aligo Dangote Chemical fertilizer recipe(
unhealthy to human organelles) that is only depended on mass importation, and
thereby given credit to other men countries. Thus, naira value has drastically
fallen down 1 US Dollar is equivalent to 900 naira only or so.
