ABSTRACT

 The effect of harrowing depth and operational speed on the performance of some tine harrow in Abia state were examined. Results revealed that the tine harrow had maximum field efficiency of 98.25% at a working speed of 10 km h-1 in clay-loam soil. The harrow had maximum fuel consumption of 7.0 litrs at operational speed of 5 km h-1, at a working speed of 8 km h-1, it recorded maximum theoretical field capacity of 0.045%, and 0.046% respectively. Results further indicated that On the other hand, the harrow recorded its maximum effective field capacity of 0.067 and 0.174% in clay-loam soil, it had minimum field efficiency of 95.60% at speed of 7 km h-1 and it achieved a minimum fuel consumption of 6.5 under working speed of 6 km h-1. The harrow attained maximum field efficiency at higher operational speeds (8-9 km h-1) as compared to other implement that achieved their maximum field efficiencies at lower operational speeds (5 - 7 km h-1). The lower operational speed ofthe harrow was attributed to the higher tractive and draft force required in its operation, to initially break up and turn over the compacted soil which is associated with slow operational speed than other tillage implements.
