A field trial with four cultivars of two-rowed spring barley was set up at the experimental field of the Secondary School of Agriculture, Požarevac, during 2012-2014 to evaluate yield and grain yield components under different growing seasons. Cultivars were sown at 450 germinating grains m-2. At tillering, the plants were fertilised with 60 kg nitrogen ha-1. The tested properties were significantly affected by weather conditions during the growing season, with different effects produced across cultivars. The values for grain yield, thousand-kernel weight, grain weight per spike, kernels per spike and plant height were highest in all cultivars in the year characterised by moderate temperatures at the grain filling stage and high amounts of precipitation in the second part of the growing season. 'Novosadski 448' exhibited the highest values for grain yield, kernels per spike and grain weight per spike.
