Increasing the productivity of the Lyudmila hemp variety by adjusting the seeding rate and using foliar fertilizers

Relevance. This study aims to increase the productivity of the Lyudmila hemp variety by adjusting seeding rates and applying foliar fertilizers. The impact of these agricultural practices on key yield indicators is analyzed.
Methods. Methods. To optimize the technological parameters of the new variety, studies were conducted to determine optimal seeding rates based on practical recommendations. The methodological basis for the scientific experiment was the guidelines for conducting field and pot experiments with hemp (1980). Statistical processing of the experimental data was performed using the methods of dispersion and correlation analysis according  to B.A. Dospekhov (1985) and the Agros software package.
Results. The Humate Plus preparation demonstrated the best results in terms of plant survival. Super Bor, Maxi Nitrogen, and Profi NPKS fertilizers most effectively stimulated plant height growth and leaf area expansion. A direct correlation (r=0.86) was found between plant height and leaf area, confirming the importance of growth stimulation during the early stages of development for maximizing yield potential. The maximum seed yield  (up to 1.67 t/ha) was achieved with a seeding rate of 2 million seeds/ha, coupled with foliar fertilization with Super Bor and Profi NPKS. A high stem yield was achieved with a seeding  rate of   3 million seeds/ha. Fertilizers with high levels of macronutrients (NPK) and boron  were the most effective for stem harvesting: Super Bor (increased yield by 3.4 t/ha) and Profi NPKS (increased yield by 2.4 t/ha).
