nutrient-use-efficiency
Nutrient-use efficiency (NUE) refers to a plant's ability to acquire, assimilate, and utilize mineral nutrients such as nitrogen, phosphorus, and potassium to produce biomass or yield. In plant science, improving NUE is a critical research goal because most crops absorb only a fraction of applied fertilizers, leading to significant economic costs and environmental problems like soil degradation and water pollution. Understanding the genetic, physiological, and biochemical mechanisms that govern NUE offers pathways to develop crops that thrive with less fertilizer input while maintaining or increasing productivity.

Two new plant-derived compounds called MiZax3 and MiZax5 can cut fertilizer use in half for wheat crops while maintaining — and in some cases exceeding — normal yields, tested across lab, greenhouse, and field conditions.
MiZax3 and MiZax5 at 5 µM with only 50% NPK fertilizer matched the root length, crown root development, and biomass of wheat grown with 100% NPK in hydroponic systems.
In greenhouse trials, wheat treated with MiZax3 or MiZax5 plus 50% NPK frequently surpassed the growth and yield of plants receiving full 100% NPK fertilization.
Grain number per spike was notably improved, indicating yield benefits extend beyond vegetative growth to actual harvest output.
