A continuous trench (width 0.3 m, depth 0.45 m)
with equalizers at a 2 m interval was constructed on
the upstream side (upper side) of the bund. In fact, the
bunds were formed out of the earth excavated from
digging of the trench. The experiment had six
treatments consisting of the combinations of three
vegetative barriers (sambuta, vetiver and lemongrass)
and two planting methodologies (bund planting and
berm planting)
