Low nitrogen and phosphorus effects on wheat Fe, Zn, phytic acid and phenotypic traits

In sub-Saharan Africa, crops are often grown under low nitrogen (N) and phosphorus (P) conditions, which may impact on the nutritional components of grains. The aim this study was to investigate effect N P a combination two iron (Fe), zinc (Zn) phytic acid content in commercial South African spring wheat cultivars (PAN3497 SST806). Phenotypic traits were also investigated. Although cultivar effects not significant, treatment highly significant for phenotypic traits. Low stress increased Fe Zn levels, whereas had opposite effect. addition, inhibited accumulation most, suggesting that treatment, more available because less interaction with acid. Compared led lower reductions number tillers, plant height, stem thickness, seeds, weight seeds dry both cultivars. While positive value wheat, negative most measured characteristics. conditions all characteristics than very detrimental yield.Significance:
