Growth model forecasting the productivity of spring wheat Lyubava background of pre-sowing seed treatment with the preparation “Ecobiosphere B” |

The subject of the study is spring wheat of the Lyubava variety, cultivated against the background of pre-sowing seed treatment with the “Ecobiosphere B” preparation in the Kostroma region. The goal is to develop simulation-dynamic seasonal forecast models to control the growth and development of Lyubava spring wheat under production conditions by pre-sowing seed treatment with the “Ecobiosphere B” preparation. The research was carried out in 2023 on the experimental field of the Federal State Budgetary Educational Institution of Higher Education of the Kostroma State Agricultural Academy. Pre-sowing treatment of seeds with the preparation “Ecobiosphere B” (1.0 l/t of seeds) contributed to the acceleration of the phenological phases of development in the middle of the growing season of spring wheat Lyubava by 7 days compared to control (without seed treatment) plants. The heat capacity of the phenological phases of development was calculated to predict the calendar terms of the dynamics of plant development from the date of sowing to harvest ripeness based on the forecast of thermal resources of the current year. The accuracy of the calculation using models for forecasting the dynamics of growth processes for the growing season with corrective efficiency coefficients for the consumption rate of the drug “Ecobiosphere B” was: “Ecobiosphere B” (0.5 l/t of seeds): plant height - 99.29%, mass of phytoorgans humidity 13 %: above-ground active phytomass - 95.25%, leaves - 89.00%, stem - 91.47%, ear elements - 97.00%, fruits - 92.00%. “Ecobiosphere B” (1.0 l/t seeds): plant height - 99.07%, mass of phytoorgans with humidity 13%: above-ground active phytomass - 91.97%, leaves - 90.08%, stem - 84.08% , ear elements - 88.69%, fruits - 88.27%. Dynamic models provide a forecast of plant productivity and yield of spring wheat Lyubava at least 80...90 days before the start of harvesting.
