Comparative Studies of Minerals between Collected and Certified Samples of Some Important Barley Cultivars Grown in Pakistan
Essential and trace elements; Na, K, Ca, Mg, Fe, Zn, Mn, Cu, Co, Cr, Ni, Pb, Cd, Ba, and Al were determined in eight barley cultivar samples collected from wheat research station, Sindh Agriculture University, Tando Jam. The dried samples were digested in HNO3 followed by H2O2, diluted with deionized water, and element were determined with atomic absorption spectrophotometer. The results were in the mg/kg range 1127.88-2312.45 (Na), 6663.3-7482.91 (K), 8.91-122.45 (Ca), 2079.08-2522.64 (Mg), 841.01-2141.9 (Fe), 30.24-53.05 (Zn), 21.93-38.69 (Mn), 7.02-10.46 (Cu), 1.66-4.41 (Co), 0.84-1.22 (Cr), 0.7-1.23 (Ni), 0.55-1.21 (Pb), 0.23-0.49 (Cd), 3.96-9.25 (Ba), and 10.42-25.35 (Al). These results of collected samples were compared with certified samples of Federal Seed Certification and Registration Department of Pakistan.
