Tillage for two of the trials was based on mechanised production while two were based on traditional ox-plough tillage. The long-term trials examined the effects of crop residue management; tillage practice and cropping sequence (i.e., continuous bread wheat (Triticum aestivum) production vs. a rotation of bread wheat with faba bean (Viciajaba)) on soil penetration resistance (PR). During 1994, 1996, 1997, 1998 and 1999, soil PR was measured in all treatments at 5 cm intervals from 0 to 30 cm in depth. While stubble management and cropping sequence had relatively minimal effects on soil PR, tillage exerted a major effect: particularly in the surface layer of the soil (i.e., 0-15 cm in depth), conservation tillage, both in mechanised and ox-plough systems, significantly increased soil PR vis-a-vis conventional tillage. Measured soil PR values were significantly associated with wheat grain yield; PR at the 0-5 cm depth was negatively related to grain yield, while PR at the 20-25 cm depth was positively related to grain yield.Collection: CIMMYT Staff Publications Collection
