Abstract:
Comparative performance o f two single donkey ploughs types (BAMRC and FARC) were compared on
two soil (sandy loam and Silty Clay) type conditions at Haromaya and kombolcha districts. Under the
parameters studied Ploughing width. Ploughing depth, effective field capacity(EEC), percentage o f weed
aversion were higher for FARC plough type(30.35cm. 12.54cm. 34.42h/ha and 89.73%) than BAMRCf
19.31cm. ]0.54cm.32.39h/ha and 61.83%) respectively under sandy loam soil condition. Working speed
and drought force are not significant (P<0.05) difference between two ploughs ty'pe. plough type was also
depend on soil condition and the two ploughs performs better under sandy loam soil type and this is due
to lower hulk density and moisture content and less weed occurrence. Ploughing depth was significantly
(P<0.05) deeper on sandy loam soils compared to silty clay soils although than difference no significance
differences (P<0.05) were observed in the drought force requirements between the soil types in this
instance. Generally: from the result obtained Modified EEC Fadis Agricultural Research Center plough
type performs higher result under two soil conditions and lower results obtained from Bako Agricultural
Mechanization research Center plough type.
