Abstract:

The aim of the study was to evaluate the impact of different levels of agricultural technology on the content of ash and minerals in grain of 8 spring barley cultivars. A two-factor field experiment was conducted in 2010-2012, at the Institute of Cultivation and Production of Malopolska Plant Growing Company, Polanowice near Krakow. The first factor was composed of two levels of agricultural technology: A1 (10/20/50 NPK kg ha-1) and A2 (additional N fertilisation in an amount of 20 kg ha-1 and an application of the fungicides Amistar 250 EC+ Tilt Turbo used in doses 0.6+0.6 L ha-1 at the shooting phase and the earing phase, respectively, as well as the growth regulator Cerone 280 SL at a dose of 0.75 L ha-1 applied in the late phase of shooting). The second factor consisted of 8 cultivars of spring barley: Blask, Stratus, Atico, KWS Olof, Nagradowicki, Rubinek, Skarb, and Suweren. Determinations of the ash content were performed by the gravimetric method according to PN - ISO 2171.1994; determinations of Na, K, Ca, Mg, Fe, Zn, Mn were conducted by flame atomic absorption spectrometry (F-AAS), and Cu (PN-EN 14084:2004) was measured by flameless atomic absorption spectrometry (ET-AAS) after mineralisation in a microwave sample preparation system (MarsXpress). The average ash content was significantly differentiated by the year of cultivation, being the highest in 2012. The average identified content of minerals, except iron, depended significantly on a cultivar and, except calcium and zinc, on a year of cultivation. Average concentrations of the majority of minerals (except Na, K and Fe) depended significantly on the applied cultivation technologies, although higher levels of the elements, except Ca, were assessed in barley cultivated traditionally (technological variant A1).
