How Much Phosphorus Uptake Is Required for Achieving Maximum Maize Grain Yield? Part 2: Impact of Phosphorus Uptake on Grain Quality and Partitioning of Nutrients

Previous studies have shown that excess phosphorus (P) uptake by maize can lead to a decreased grain yield. Part one of this study demonstrated experienced luxury consumption P in three phases uptake. The objective work was further explore how indirectly impacts the other nutrients and their translocation within plant explain yield penalty associated with consumption. Three hybrids were grown under optimal conditions using sand-culture hydroponics for precise control root environment. Plants maturity six different concentrations followed biomass nutrient partitioning analysis various parts. All non-P achieved maximum content at levels coincided yield, while K, Mg, Mn, B, N, S, Fe into non-grain tissue continued With beyond point corresponding Fe, Cu, Zn significantly along consumption, Zn, accumulated roots. Grain production may been limited P-inhibited from roots grain. This decrease did not prevent growth since those as limiting they Data suggest these micronutrients protein production, which evident N S concentration concomitant
