Preliminary studies on the production capacity of triticale ( Triticosecale Wittmack ) grains under the influence of fertilization and varieties

Literature contains numerous data on the distribution of minerals in soil and plants from spontaneous flora or cultivated in different geographical areas, as well as a series of mineral analysis techniques. The aim of this study was to determine the concentrations in K and Ca of Cirsium arvense, Agropyron repens and Medicago sativa using x-ray fluorescence spectrometry. This study was conducted on a cambic chernozem, in seven location in Dumbravita (Timis County) area. The tested plants accumulated Ca and K differently. The mineral content of whole plants are expressed on a dry matter basis. In Cirsium arvense and Medicago sativa total calcium content is higher than total potasium content but in Agropyron repens the ratio is reversed.The average values of the content of Ca (mg/kg d.w.) has a downward trend: Cirsium arvense> Medicago sativa> Agropyron repens. The trend for K (mg/kg d.w.) is: Medicago sativa> Agropyron repens> Cirsium arvense. Comparing our results, obtained by using x-ray fluorescence spectrometry with literature, the values are similar, so we consider that this method can be used for a rapid monitoring of the mineral contents in forages, but it is necessary to make other researches in future on this theme.
