During the period 2011–2013, microplot experiments on spring barley were carried out in the experimental field of the Institute of Soil Science and Plant Cultivation in Pulawy, on a good wheat soil complex. The following cultivars were compared: Basic, Goodluck, Iron, KWS Aliciana, Natasia (series 2011–2012) and Despina, Ella, Fariba, Gawrosz (naked), Kucyk i Raskud (series 2012–2013) in terms of their characters determining grain yield and their response to sowing date: 1–5 April and 10 days later. The delayed sowing date caused decrease of number of ears per unit area and grain yield, and increase of protein content in grain, but did not result in significant changes in the number of grains per ear and in 1000 grain weight. Goodluck i Natasia, Ella, Gawrosz and Kucyk with higher tillering ability, can be considered to be cultivars more tolerant to delayed sowing date.

Among the cultivars tested, there were large differences in productive tillering of plants, number of ears per unit area, and grain yield. Smaller differences related to number of grains per ear and 1000 grain weight. Natasia, Kucyk and Ella were characterized by high grain yield thanks to higher number of ears. Iron and Raskud were characterised by the highest number of grains per ear.
