A push, and a pull, to enhance nitrogen use efficiency in rice

Nitrogen (N) is a macronutrient that is essential for plant growth and development, which is required for the synthesis of a myriad of important biomolecules, including amino acids, proteins, nucleic acids and hormones such as auxin and cytokinin (Yang et al., 2015). Consequently, plant productivity depends heavily on N fertilization and N is a major limiting factor for agriculture. This is particularly apparent in African agriculture given that...
