Abstract
An investigation was carried out to study the “Soil microbial
population is the mirror of soil health” under incubation
in the Department of Soil Science and Agricultural Chemistry, Institute of
Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar-pradesh. The
experiment were laid out in Completely Randomized Block Design with twelve
treatments replicated three times. N, P, K were applied through urea, single
super phosphate and muriate of potash, respectively. While the total amount of
organics were applied 14 days before incubation study. Microbial population of
the experiment under incubation as bacterial population g-1soil x105,
control (T1) treatment was show lowest at different days of
incubation. There was an increase in microbial population of other treatments
due to addition of organic and inorganic sources of nutrients at each days of
incubation. Addition of fertilizers and manures either in combination or in
alone has significantly shown as increase in bacterial population over control
(T1). The highest and lowest bacterial population was recorded at 90
and 0- days of incubation; whereas the treatments receiving 100% N through FYM
were showed maximum population of bacteria through-out experimentation periods.
The at par values were observed in the treatments of T3 to T7
and T8 to T12 except T8 and T12
treatments at different days of incubation. All the treatments show superiority
over initial value of bacterial population through-out incubation periods. The
population of fungi was maximum and minimum observed at 60 and 0- days of
incubation due to different treatments under different periods of incubation.
Incorporation of nitrogen through alone organic treatments (T8 to T12)
increased significant fungal population over control (T1). Similar,
to the population of bacteria; fungal pupation has also showed maximum and
minimum population in the treatments of 100% N through FYM (T8) and
control (T1) respectively, through out the experimentation periods
under incubation study. Among the treated conditions alone nitrogen through
organic sources given better response over other treatments under incubation at
different days. Most of the values were at par with each other in the treatment
of integrated approaches (T3 to T7) and organic alone
treatments (T8 to T12) in respective days of incubation.
Declined trend was started from 90 days of incubation in all the treatments in
fungal population over 60 days of incubation. Application of N through organic
manures / wastes alone treatment (T8 to T12) were
recorded maximum population of actinomycetes over other treatment under
incubation study at deferent days. Similar, to the population of bacteria and
fungi the highest and lowest population of actinomycetes were recorded in the
treatments receiving FYM alone (T8) and control (T1),
respectively at different days of incubation. Among the different days of
incubation the maximum and minimum values were observed at 60 and 0- days
respectively. Most of the values were at par with each other in the treatment T3
to T7 and T8 to T12; except T8 and
T10.
