Abstract
The purpose. To determine influence of periods of sowing and seeding rates on amount of grains in an ear and productivity of grain of spring barley. Methods. Count, weighting, statistical. Results. It is fixed that with each subsequent sowing amount of grains in an ear decreased. The same is observed at increase of seeding rate. Action of probed factors on productivity of grain of spring barley is fixed. Level of productivity essentially dropped with each subsequent sowing. Conclusions. Increase of seeding rate results in significant drop of productivity at periods of sowing on 15.03. and 25.03. At sowing on 05.04. essential variance is fixed between values of productivity for seeding rates 350 and 400 pieces/m2. In next periods of sowing differences between productivity of probed seeding rates were negligible.

Key words: barley, periods of sowing, seeding rate, amount of grains, elements of yield, stages of organogenesis.
