Macro- and Micornineral Contents of Yellow-Fleshed Cassava Roots Across Genotypes, Locations, and Sets 1 and 2  
The macro- and micromineral contents of yellow-fleshed cassava root across all the genotypes and locations are presented in Table 1. The most abundant mineral in cassava storage roots was potassium (K), with concentrations ranging from 4300 to 26,000 mg/kg with an overall mean of12,116 \(\pm\) 3543.58 mg/kg for trial 1, and ranged from 6300 to 38,000 mg/kg with a mean value of 17,883.60 \(\pm\) 4898.77 mg/kg for trial 2. However, the least abundant mineral was sodium (Na), with concentrations ranging from 15.68 to 2100 mg/kg with an overall mean of 228.22 \(\pm\) 316.74 mg/kg for trial 1, and from 11.47 to 186.73 mg/kg with a total mean value of 39.19 \(\pm\) 23.41 mg/kg for trial 2. The results also showed that trial 2 had higher concentrations of calcium (Ca), magnesium (Mg), and potassium (K) than trial 1. Still, trial 1 sets had a higher content of Na, P (phosphorous), and S (sulphur). It could be deduced that the storage roots of cassava could be a good source of these macroelements, especially potassium. Diets rich in minerals are essential for proper growth and development [11]. This result agrees with [PERSON] et al. [16], who reported that the highest mineral content of the cassava samples studied was K (269 mg/kg), but contradicts with [PERSON] et al. [17]. Among the mineral compositions of the four cassava samples they studied, Mg was the highest mineral found in all four cassava samples investigated, with values ranging between 185.1 and 321.5 mg/kg. [PERSON] et al. [18] studied some local and improved high-yielding and cassava mosaic disease (CMD)-resistant cassava varieties grown in Uganda. The findings of this study indicated that the levels of minerals differed with the cassava variety. The cassava yellow root genotypes for both trials and 1 and 2 had very low Na, and this indicates that these genotypes could form part of a low-sodium diet. However, K regulates the osmotic pressure within the cell, and is involved in cell membrane transport and the activation of several glycolytic and respiratory enzymes. Potassium intake in a regular diet is 2-5.9 g/day. The minimum daily requirement is estimated to be 782 mg. It implies that cassava, with a high level of K and low Na, might be an ideal crop to consume to reduce hypertension, although this needs further research evidence.  
The most abundant mineral in cassava storage roots was manganese (Mn), with concentrations ranging from 7.390 to 39.990 mg/kg with an overall mean of 16.511 \(\pm\) 6.200 mg/kg for trial 1, and ranging from 4.540 to 42.680 mg/kg with a mean value of 13.383 \(\pm\) 4.698 mg/kg for trial 2. However, the least abundant minerals were molybdenum (Mo) and cobalt (Co), with concentrations ranging from 0.600 to 0.700 mg/kg with an overall mean of 0.694 \(\pm\) 0.025 and 0.675 \(\pm\) 0.043 mg/kg for trial 1, and ranging from 0.600 to 3.000 mg/kg with total mean values of 0.708 \(\pm\) 0.237 and 0.696 \(\pm\) 0.239 mg/kg for trial 2, respectively. The results also showed that all the minerals in trial 2 had higher concentrations than trial 1, as found for macrominerals. It could be deduced that the storage roots of cassava could be a good source of these microelements, especially Mn.
