Two cultivars of winter wheat. EBI and ESTICA , were grown in stands of different densities (with 250 and 500 seeds sown per l mg respectively) and in two periods of sowing (September and October). ln the vegetative period there was a loss of pl ants during the period of sowing and germination of about 20% and with the higher sowing rates of up to 30%. With late sowing, 45 to 55% plants were lost during germination. Overwinterin g was worse in the stands that had been sown later, due to in sufficient cold resistance. Tests for existing frost resistance in both years showed higher values of frost resistance at denser sowing rates. lt has not been demonstrated that trost resistance under the conditions of ecological agriculture is worse.
