Abstract
Comparative study of important macro and micronutrient elements between two varieties of rice, i.e. Kashmir Nafis and NIAB IRRI-99 as well as its soil have been carried out using Atomic Absorption Spectrometry. Maximum concentration (mg/kg) of macro-elements Na and K were found in Kashmir Nafis rice variety (i.e. 478, 3668) respectively, whereas highest concentration (2542) of Mg was found in NIAB IRRI-99 rice variety. Highest amount (mg/kg) of micro-elements Zn, Mn, and Cu were found in NIAB IRRI­99 rice variety (i.e. 43.09, 56.31 land 6.48) respectively, while the highest concentration of Fe and Ca (1043 and 77.68) respectively, were found in Kashmir Nafis rice variety. Maximum concentration (mg/kg) of Al and Ba were found in NIAB IRRI-99 rice variety (i.e. 17.02 and 5.77) respectively. The high level (mg/kg) of Cd, Cr and Ni were found (i.e. 0.392, 1.01 and 1.90) in Kashmir Nafis rice variety and the maximum concentration of Co and Pb were found (i.e. 4.70 and 1.20) respectively in NIAB IRRI-99 rice variety. The concentrations (mg/kg) of the soil was determined for Na, K, Ca, Mg, Zn, Fe, Mn, Cu, Al, Ba, Ni, Pb, Co, Cd and Cr (3284, 2457, 3204, 41519, 91, 5731, 536, 25.65, 35964, 111, 16.66, 5.64, 13.52, 1.95 and 13.63) respectively from the same place where both varieties were grown.
