Mushrooms are excellent nutritional and medicinal sources in the environment. This study has sought
to conduct an analysis of the concentration of the essential elements in the mushroom sample that was
cultivated on three supplementary substrate compositions (25% Vallisneria aethiopica and 75% Tripochton
scleroxylon, 50% Vallisneria aethiopica and 50% Tripochton scleroxylon and 75% Vallisneria aethiopica and
25% Tripochton scleroxylon) using Instrumental Neutron Activation Analysis (INAA) at the Ghana Research
Reactor-1 facility(GHARR-1). The concentrations of the elements were detected in Pleurotus ostreatus
cultivated on three different percentage substrate compositions of a mixture of Vallisneria aethiopica and
Triplochiton scleroxylon. The mixture of 50% Vallisneria aethiopica and 50% Tripochton scleroxylon was best
for most of the cultivation of oyster mushrooms since most of the elements detected in the samples attained the
highest concentration in this substrate. The validity of the INAA technique for determination essential elements
was checked by analyses of SRM 1566b (Oyster tisue) and Peach leaves 1547, respectively. The mean
concentrations of the nutritional elements (Al, Cs, Ca, Cu, Cr, Cl, Zn, Br, Hg, Th, Fe, K, Mg, Mn, Na and V)
were determined in mushrooms cultivated on three different substrate mixtures.
