Corn is cultivated as a strategic crop in most parts of the world to meet animal and human feed needs. In this study, there is an attitude that nitrogen fertilizer and conservation tillage (CT) can be useful in increasing and improving the desired yield of corn and reducing economic costs. On the other hand, the development of tillage systems and farmers' acceptance of them requires a serious study of these factors on the growth and yield indicators of corn and weed management. This study showed that the growth and development of corn are very much affected by nitrogen; therefore, nitrogen fertilizer's optimal use is essential. The quantitative and qualitative yield of corn is affected by the type of tillage system. CT has shown more promising results over several consecutive years. Weed flora is affected by tillage and nitrogen fertilizer in terms of density and species diversity of weeds in fields. Therefore, proper management is necessary to maintain all aspects of environmental agriculture to use the type of tillage systems and the optimal use of nitrogen fertilizer to control weeds. Therefore, this study was intended to guide further studies in the future for further investigation. However, little information was available on the effects of CT and nitrogen on corn weeds. However, an attempt has been made to examine some of the critical factors more prominently that significantly affect maize's agro-ecophysiological properties.
