Abstract:
The paper presents and analyzes the grain production level of the common winter wheat variety of local origin „BLAGODARKA OD ESSKAIA” in polyfactorial experiments under the effect of the forerunners sunflowers and corn for grain on the recommended, admissible and late planting dates with various sowing density. Under the conditions of the agricultural year 2016- 147 2017, it was proved the priority of the forerunner sunflower compared to corn for grain, which provided 4730,9 kg/ha due to more favorable conditions for plant growth and development. The yield of kernels after the forerunner corn for grain constituted 3223,4 kg/ha or by 1507,4 kg/ha less. The planting dates taken into consideration by the study did not influence positively the production. The common winter wheat variety „BLAGODARKA ODESSKAIA” recorded a statistically significant positive gain of 432,4 kg/ha being sown after the forerunner sunflower at a planting density of 6.0 million viable seeds per hectare on admissible planting dates in the second decade on October.
