Maize is one of the most important cereal crops grown in tropical and temperate regions of the world. Despite its high yield potential, it is giving low yields because of lack of appropriate information on plant geometry and fertilizer management. Nitrogen, phosphorus and potassium are the major plant nutrients, which limit normal plant growth. Increasing productivity per unit area through agronomic management is one of the important strategies to increase the production of maize grain. Keeping this in view, an attempt was carried out to review the work done on the effect of spacing and fertilizer levels on yield and economics of maize hybrids. In maize, the effect of plant density and fertilizer levels is well documented. From the review, it is understood that the response of hybrid maize to plant density and fertilizer requirement varies widely. Summarizing the review undertaken, it can be concluded that the potential productivity of hybrid maize could be achieved when it is grown under optimum spacing of 75 x 20 cm and high fertilizer levels of 200:100:100 NPK Kg ha -1 under irrigated condition.
