The Green Revolution of the 1960s improved crop yields in part through the widespread
cultivation of semidwarf plant varieties, which resist lodging but require a high-nitrogen (N) …

Abstract Nitrogen (N), potassium (K), and phosphorus (P) are essential macronutrients for
plant growth and development, and their availability affects crop yield. Compared with N, the …

Nitrogen accounts for approximately 60% of the fertilizer consumed each year; thus, it
represents one of the major input costs for most nonlegume crops. Nitrate is one of the two …

The elevation of atmospheric CO 2 concentration has a strong impact on the physiology of
C3 plants, far beyond photosynthesis and C metabolism. In particular, it reduces the …

Modern agriculture relies on mineral fertilization. Unlike other major macronutrients,
potassium (K+) is not incorporated into organic matter but remains as soluble ion in the cell …

Nitrogen (N) availability is a major factor determining plant growth and productivity. Plants
acquire inorganic N from the soil, mainly in the form of nitrate and ammonium. To date …

Salinity stress is considered the most devastating abiotic stress for crop productivity.
Accumulating different types of soluble proteins has evolved as a vital strategy that plays a …

Nitrogen (N) is an essential macronutrient that affects plant growth and development. N is an
important component of chlorophyll, amino acids, nucleic acids, and secondary metabolites …

Nitrogen availability is a major factor determining plant growth and productivity. Plants
