Abstract
The paper reveals the dynamics of the increase in raw and absolutely dry aboveground weight of spring wheat and triticale plants. The research was conducted using the spring wheat of Elehiia Myronivska variety and the spring triticale of Solovei Kharkivskyi variety on the southern chernozem in the educational and scientific-practical center of Mykolaiv NAU in 2014–2016. According to the results of the three-year research, it was established that during the tillering stage the raw above-ground weight of spring wheat, due to presowing seed treatment, increased by 9.9%, triticale – by 10.8%. The increase in the absolutely dry aboveground weight was 11.9% and 11.8%, respectively. In the booting stage, the increase in the raw weight of the spring crops varied within the limits of 9.7–10.1%, absolutely dry weight – 10.0–10.1%. A similar increase was also detected in the heading stage. The fertilized spring wheat plants accumulated up to 23.6% of dry weight in the tillering stage, 58.3% – in the booting stage, and 92.5% – in the heading stage of the total amount of dry weight at the stage of complete grain ripening, while the unfertilized plants were 15.0%, 33.0% and 64.6%. Similar indexes for spring triticale were: 24.5; 62.0; 89.3% for the fertilized plants and 15.8%, 35.1%, 69.3% for the unfertilized plants.
