erosion compared with grass cover. The prediction of erosian under the cassia vera were
14.25 t/ha/year, while on grass vegetation it was 24.46 t/ha/year. So cassia vera can be
used as a conservation plant. This effect will be prolonged if yields are harvested in the
form of peeled bark rather than cutting trees (Syakir and Hermanto, 1995). Dijisbar
and Dhalimi (1996) indicated that in a sloping area, such as in Singkarak lake, west
Sumatera, alley cropping was recommended using Sloping Agriculture Land
Technology. Contour lines and seed beds 20 cm wide and 10–15 cm high are prepared
and cassia vera plants are planted between two contour lines as a main crop along with
annual crops such as corn, dry land rice and legumes as intercrops. If sloping increases
up to 15–30%, then each contour line consists of one swallow ditch, one line of king
grass and one line of vetiver. With 30% slope, each contour line consists of one swallow
ditch, one line of vetier and two lines of king grass. Cassia plants are planted
between two contours. This has been proven to be an efficient method for cultivating
sloppy lands.
