Abstract
Field experiments were conducted in the district
Sultanpur, U.P., from May 2019 to March 2021 to study the effect of
conservation agriculture (CA) practices on carbon stock, carbon sequestration
and soil biological properties. Rice - okra- green manure cropping system with
conservation practice were compared with ricce - okra cropping system without
conservation practices keeping the same layout for two years. Conservation
agriculture practices had significant influence on carbon stock, carbon
sequestration and soil biological properties. After six cropping sequence,
conservation practices such as direct sowing rice in flat bed + green manuring-
okra+ crop residue mulch-cowpea had the maximum soil carbon sequestration of
9.52 Mg ha-1and 6.03 Mg ha-1, at 15 and 30 cm soil depth,
followed by direct seeding rice in flat bed + brown manuring- okra+ crop
residue mulch-cowpea (10.17,6.07 Mg ha-1). The treatments without
conservation agriculture practices, such as direct seeding rice in flat beds -
okra-fallow, had a negative sequestration value.The highest microbial biomass
carbon 134.83μg g-1)
was recorded in direct seeding rice in flat bed + brown manuring - okra + crop
residue mulch-cowpea. Dehydrogenase activity was found to be
significantly highest in direct seeding rice in flat bed + brown manuring - okra + crop
residue mulch-cowpea (57.17 μg TPF g-1
soilday-1) and it was on par with direct seeding rice in flat
bed + green manuring –okra + crop residue mulch-cowpea (T4) (57.17 μg TPF g-1 soilday-1).
