Maize being an exhaustive crop demands for higher fertilizer application, especially N fertilizer and the addition of nutrients through fertilizers is, however, far below the crop removal. Exploring low -cost agronomic practices is highly imperative in the present day agriculture to increase farmers profitability and environmental safety. Further, while devising fertilizer N recommendations to a crop it is necessary to consider cropping sequence as a whole rather than that individual crop per se because the need for nutrients by a crop would vary depending upon the preceding crop type and its inputs usage. This review provides an update on the research undertaken on productivity and nitrogen requirement of maize as influenced by preceding cropping practices.
