While methods of rotating crops and maintaining residues proved to be effective over the long range of the study, it took some 5 years for yield benefits to emerge. Moreover, the research also demonstrated that there was not a significant difference in yield when some of the surface cover was removed. It is suggested that this could be a positive sign in encouraging smallholder adoption as it allows for multiple uses of crop residues for fertility gains and the maintenance of livestock.text/plainen-USIn CopyrightRainfed agricultureSoil erosionConservation agricultureConservation tillageCrop rotationsResidue managementTriticum aestivumZea mays l.Zero tillagePermanent bedsWheatMaizeField ScaleAbstractCopyright 2004 Elsevier B.V.
