Treatment — oriented land capability analysis reveals that 27.10 
and 27.50 percent land falls under capability class C1 and C2 
suitable for cultivation with suitable conservation measures 
(Table 3) . Strip cropping, bench terrace, broad base terrace, 
vegetative barriers and mulching are suggested to adopt as 
conservation measures in crop land.

land cover and physiography map to derive input parameters of 
USLE and SYI model. Spatial analysis with GIS helped to 
identify the factors contributing soil loss that can be used as 
indicator while preparing conservation plan of the watershed.
