The growth rate of each plant (dry matter accumulation rate) mainly depends on sun’s energy interception (electromagnetic radiation) and leaf nitrogen (N) content for carbon assimilation. Radiation use efficiency (RUE) is an essential factor utilized by many of the simpler plant growing models to simulate the process of photosynthesis, i.e., conversion of light energy and carbon dioxide (CO2) to plant biomass. The productivity of crop is limited by its thermodynamic properties and the sustained climate of both the plant and its ecosystem. The application of industrial N fertilizers in agricultural production has enhanced the crop yield two to three times more in the last century to meet the rising worldwide population demands. This chapter is focused on the efficient use of solar radiations and integrated N management to enhance crop nitrogen production, taking into account soils, increased utilization of fertilizer, and better crop management strategies. Therefore, optimizing the efficiency of radiations and nitrogen use in agricultural systems is critical and yet to be explored.
