Abstract


A field experiment was conducted under using universal soil loss equation, run off plots installed with multislot devisors for evaluating the impact of different soil management treatment on run off, soil and nutrient losses in rabi sorghum- sunflower production system at Regional Research Station, Bijapur in Vertisol for three years from 1998 to 2001. The data when averaged over three years Indicated that the per cent run off and annual soil loss were minimum in the treatments receiving retention of either sorghum stubble /sunflower stalks @ 2.5 t/ha (20.47% and 3.52 t/ha) on the soil surface followed by in situ incorporation of sunhemp  @ 5t/ha (21.05 % and 5.83 t/ha) and FYM application @ 5t/ha (24.34 % and 7.59t/ha). Among all the treatments, farmers practice recorded maximum runoff of 29.13% and annual soil loss of 9.98 t/ha respectively.
