Medicinal significance of vegetables cultivated over minerals supplemented soil

Three winter season vegetables Fenugreek/Methi (Trigonella-foenum-graceum), Sarson (Brassica-campestris-var-sarson) and Garlic (Allium-sativum) were included in the present study to determine some of their mineral components and see if some of their mineral (Cr, Zn, Mn, Cu, Mg and Fe) content could be increased by supplementation through their roots. Thus calculated amount of Cr, Zn, Mn, Cu, Mg and Fe salts (as fertilizer) were applied in solution form to the roots of vegetables in different concentration as individual or in combinations. These vegetables were grown from seeds in the soil plot. After harvesting vegetables were dried, acid digested and analyzed for Cr, Mn, Zn, Cu, Fe and Mg on Hitachi Zeeman Japan Z-8000, Atomic Absorption Spectrophotometer. Thus in Fenugreek/Methi (Trigonella-foenum-graceum) total increase of Cr, Zn, Mn, Mg and Fe recorded was (10, 94, 10, 256 and 520) mg/Kg dry weight basis; in Sarson (Brassica-campestris-var-sarson) total increase of Cr, Zn, Mn and Mg recorded was (12, 30, 22 and 424) mg/Kg dry weight basis and ( Garlic) (Allium-sativum) total increase of Cr, Zn, Mn, Cu, Mg and Fe recorded was (14, 28, 4, 4, 116 and 10) mg/Kg dry weight basis. From the present study it can be concluded that by changing the soil minerals environment the uptake of required mineral content of vegetables, perhaps could be enhanced. This could play important role in management of diabetes control and also in the elimination of other deficiency diseases like anemia. (author)
