The experimental treatments and crop
management
Each experimental unit (plot) was 8 m wide and
60 m long with two cross bunds at a horizontal
distance of 20 m. Figure 1 shows the installation of
vegetative barriers along with bunds/trenches/berms
and the runoff gauging devices in the experimental
plots. Each experimental plot was bounded on all
sides by a well compacted earthen bund and a
shallow drainage channel to prevent the influences
from outside. At the lower end of the plot, a
galvanized iron (GI) plate was placed along the bund
and compacted with a hard soil to obstruct the runoff.
At the center of this reinforced bund, a multi-slot
divisor having five slots was installed. The spout of
the multi-slot divisor was connected to a
1 9 1 9 1 m runoff collection tank constructed with
bricks and mortar.
