The influence of sowing dates and seeding rates on stem and spike productivity was studied in modern winter wheat varieties (Podolyanka, Kolchuga, Kosovyca, Natalka and Blagodarka Odesskaya) under conditions of the southern steppe of Ukraine. It was found that the number of spike-bearing stems per unit area and grain weight per spike have a dominant role for the yield of this crop. The maximum value related to the number of productive stems were recorded by the plants sown on 30 of September with a seeding rate of 5 million pcs/ha. Spike productivity of all varieties was higher when the sowing was done at late dates with a seeding rate of 3 million pcs/ha.
