Nigeria's agricultural policy is the synthesis of the framework and action plans of Government designed to achieve overall agricultural growth and development. The policy aims at the attainment of self-sustaining growth in all the sub-sectors of agriculture and the structural transformation necessary for the overall socio-economic development of the country as well as the improvement in the quality of life of Nigerians. The small-holder farmers are vital for Nigeria's agriculture and rural economy. They are defined as those marginal and sub-marginal farm households that own or/and cultivate less than 5.0 hectares of land and constitute about 70 per cent of the country's farmers. This paper therefore reviewed the Nigerian agricultural policy influence as it affects small holder farming. It reviewed the Nigerian agricultural policy landscape and the new national agricultural policy as they affect some macro-economic policies since the post- civil war era.
