| Summary: | Treatment with biological products resulted in an increase in the area of the assimilation apparatus by 1.7 to 2.4 thousand m²/ha.The application of Bio-gel led to an increase in leaf surface by 1.7 thousand m2/ha or 5.3%, and the treatment with Helafit combi by 2.4 thousand m2/ha or 7.5%. The treatment with biological products contributed to an increase in photosynthetic potential by 5.1% compared to the treatment with Bio- gel and by 7.2% compared to the treatment with Helafit combi. It was found that the treatment of parental lines with Bio-gel and Helafit combi caused an increase in laboratory germination of seeds. When using Bio-gel, the laboratory germination rate increased by an average of 1.5%. The treatment with Helafit combi was more effective, as the germination rate in this experimental variant increased by 2.4%. The increase in laboratory germination was observed due to a decrease in the infection of seeds of the lines by Fusarium moniliforme Scheld. The maximum seed yield in the early maturing line - the parent component of DK 281 was recorded at a density of 90 thousand plants/ha and treatment with Helafit combi - 3.65 t/ha. The maximum yield in the line - the parent component of DK 247 was observed at a density of 80 thousand plants/ha and treatment with Helafit combi - 4.89 t/ha. The medium-late line - the parent component DK 411 showed the highest yield at a density of 70 thousand plants/ha and treatment with Helafit combi - 4.65 t/ha. The maximum yield in the experiment was observed in the line |
