Conventional Tillage (CT) (control) |
Farmers frequently use a
tractor-mounted moldboard plough to a depth of 20–25 cm for 4-6 times
during the fallow period after clearing or burning previous crop
waste. |
NT |
After the main crop was harvested, the previous crop wastes were
removed, leaving the land naked and uncultivated until the following
planting, which was primarily done with a no-till planter. Weedicide was
used to control weed growth. |
RT |
After the main crop was harvested, previous crop residues were cut
down, and the soil was inverted, plowed to a depth of 25 to 30 cm, and
generally harrowed at a depth of 5-8 cm in the primary
tillage. |
ST |
After the primary crop was harvested, previous crop leftovers were
cut down, and the soil was plowed deeply by a soil chisel to a depth of
30-35 cm, with its movable wings making a 60 cm gap between its
ends. |
