Quantitative assessment of trace and macro element compositions of Cassava (Manihot esculenta) storage roots enriched with Β-Carotene as influenced by genotypes and growing locations

Cassava’s important mineral contents depends on some factors, including
genetic and growing locational factors. The study aimed to evaluate the
influence of genotype and growing locations on the mineral concentrations
in yellow-fleshed cassava root genotypes. Twenty-five pipeline
yellow-fleshed cassava genotypes and three white-fleshed varieties (check
samples) were planted at five different experimental fields for two
seasons, each representing the major agroecological zones in Nigeria.
Standard laboratory protocols were employed in the sampling to ensure zero
contamination, and the trace and macro elements were determined using the
inductively coupled plasma optical emission spectroscopic method (ICPOES).
The trace and macro elements identified in all the genotypes and varieties
investigated were Fe, Mn, B, Cu, Mo, Co, Ni, Zn, and Al; Ca, Mg, Na, K. P,
and S respectively. Genotype and growing location had a highly significant
(p < 0.05) effect on all the trace elements except Ti and Cr.
However, there was no interactive effect between genotype and growing
location on all the trace elements except for Pb and Zn. Among the
explanatory variables, the variable growing location was the most
influential on macro and trace elements. Conclusively, genotypes 01/1442
and 01/1273 have outstanding trace and macro element concentrations.
