abstract: Micro-plot study aimed at estimation of the influence of pre-sowing seed stimulation using electromagnetic wave generator on the yielding, yield structure elements and grain chemical composition of naked and hulled spring barley and oats varieties was performed in 2002-2004. The following traits were examined: ears (panicle) density, grain and protein yields, weight and number of grains per ear (panicle), weight of 1000 grains, as well as bulk density. Nitrogen, fibre, oil and ash contents in grain were also determined. Pre-sowing seed stimulation using electromagnetic wave generator affected the yields, yield structure elements and grain chemical composition under statistical error limits. However, a tendency to increase grain yield of naked varieties (spring barley by 3.0% and oats by 4.1%) was observed as a result of seed irradiation. Hulled varieties of barley and oats yielded higher by 31.6% and 20.8%, relatively as compared to naked forms of the species. The lower level of naked barley yielding resulted most of all from lower ears density in comparison to hulled barley. Naked oats yielded worse than the hulled form due to lower weight and number of grains per panicle. Fibre concentration in naked forms grains of both species was lower than in hulled. Naked oats contained more protein and oil as well as less ash in grains than hulled oats.
