Abstract

In this review maize is highly sensitive cereal crop to most agronomic practices such as plant population density and plant spacing. Plant population density and row spacing is one of the best agronomic practice to increase maize crop productivities. Depending on the environmental yield potential of the land, improvements of intera and inter row spacing practices are important for land productivity to each maize varieties. The optimum plant population density that increases the yield and yield components of a single plant. As the review indicates most yield components of maize varieties are affected by plant population density and row spacing due to resource competition results yield reduction. As the plant population increase per cultivated land area, economic yield and above ground biomass yield was decreased. Similarly the narrowest intera and inter row plant spacing decreases economic yield and above ground biomass yield of maize crop.
