Evaluation of various preparatory operations for analytical recovery of selected plant nutrients in grains of wheat (Triticum aestivum), lentil (Lens culinaris) and rapeseed (Brassica napus)
Abstract
Laboratory techniques involved in analytical procedure poses many complications on the results that influence the efficacy of research work. An experiment was conducted to study the effect of washing, grinding and digestion methods on K, Zn and Fe concentrations in grains of wheat, lentil and rapeseed. The investigation was undertaken at the laboratory of National Agricultural Research Centre (NARC), Islamabad. The samples were divided into two sets; one was washed with distilled water and other was processed unwashed. Four different grinders namely Kinematica Model PX–MFC, J 200 GE 247–A, Cyclotec 1093 and mortar & pestle were used for sample grinding. The samples were subjected to dry ashing as well as wet digestion (HNO3 + HClO4). The results showed that K, Zn and Fe concentrations affected significantly with different washing methods, grinding machines and digestion procedures. Washing as well as dry ashing decreased K, Zn and Fe contents.
