Salinity in agriculture creates a menace when exceeds
the threshold limit, impacting heavily both soil and plants
grown on it. K-fertilizer and mulching are often proposed to control salinity. In this backdrop, our study was aimed
to analyze the effect of four important soil enzymes by
combined application of muriate of potash as potassium
fertilizer (control, 30, 60 kg K ha-1) and mulching (with and
without polythene mulch) under saline irrigation (control,
2.0, 4.0 dS m-1) during the active crop growth stages (50
and 100 DAS) in peanut (Arachis hypogaea L.) crop during
summer, 2014. Results revealed that polythene mulching
could effectively reduce the electrical conductivity of
saturation extract of soil (ECe) across the salinity levels.
The differentiating effects under mulching and potassium
treatments were also observed for each of the enzymes
studied. Dehydrogenase, acid phosphatase and FDH
enzymes recorded more activity at 50 DAS than 100 DAS,
while alkaline phosphatase and urease showed reverse trend.
However, the benefits of using ameliorants like mulching and
potassium fertilizer for soil biological activity under peanut
crop were found to be salinity treatment specific, either at
higher irrigation salinity (4.0 dS m-1) or at non-saline or
lower irrigation salinity (2.0 dS m-1) plots. To reduce the
impact of salinity both the ameliorants may or may not
act jointly as observed in the present study. Overall, our
study inevitably established the usefulness of mulching and
potassium fertilizer for sustenance of soil biological health
under salt-prone arid and semi-arid regions.
