Abstract

The objective of this research was to determine the uptake of different elements (K, Mg, Ca, Na, Fe, Co, Mn, Pb, Cu, Zn and Ni) which are used as nutrients by the rice crop. Different types of rice seeds KSK-282, KSK-134, BAS-515, IR6, BAS-2000, KSK-133 and super-BAS were collected from National Agricultural Research Centre (NARC) Islamabad Pakistan and grown in different plastic pots containing soil under the same condition. Ten days old immature plants of different varieties of rice were dried and their roots were separated from the whole plants. The dried roots were ground into fine powder followed by acid digestion (HNO , H SO and 3 2 4 HClO ) solution in a ratio of (5:1:0.1) individually. After digestion the solutions were filtered and the filtrates 4 were diluted by adding distilled water. The diluted solutions of all the above mentioned varieties of rice were analyzed by Atomic Absorption Spectrophotometer (AAS) for nutrients (K, Mg, Ca, Na, Fe, Co, Mn, Pb, Cu, Zn and Ni) concentration. The different values obtained from AAS had shown that some rice varieties had taken up nutrients (elements) in large amount (e.g., KSK-134 had taken up maximum Fe while KSK-133 had taken up minimum) as compared to other varieties. Similarly, several verities absorbed comparatively minimum concentration of elements. The results obtained in this research work clearly indicated that the absorption of these elements from the soil was dependent on the rice variety (e.g., BAS-2000 absorbed maximum Mg while minimum Super-BAS). Interestingly most of the rice vaities had absorbed the beneficial elements in large quantity as compared to other toxic elements.
