Тип записи:Публикация, Effect of O,O-diethyl-1-(3,4-dimethoxyphenyl)-(1-ethynylcyclohexylaminomethyl)phosphonate on growth, and yield of vegetable crops(Instituto Internacional de Ecologia (Brazil), 2026-01-01); ; ; Abstract This study investigates the effect of O,O-diethyl-1-(3,4-dimethoxyphenyl)-(1-ethynylcyclohexylaminomethyl)phosphonate (BA-3) on seed germination, plant growth, and yield of agricultural crops, including carrot, beetroot, and potato. The results indicate that seed germination increased by 14.0% and 27.0% at BA-3 concentrations of 0.002% and 0.0002%, respectively, compared to the control. Laboratory experiments demonstrated that treatment with BA-3 (0.0002% solution) enhanced germination energy by 16.0% and 22.0%, respectively. The reference standard HAU (0.06%) improved germination energy by 13.0% and overall germination by 12.0%. In addition, treatment of potato tubers with BA-3 resulted in a significant increase in the number of awakened buds, by 43.0% at 0.002% and 53.0% at 0.0002%, relative to the control. Field trials showed that the application of BA-3 at a concentration of 0.002% increased carrot yield by 4.0 t/ha (18.2%), while at 0.0002% the increase reached 4.8 t/ha (21.8%). For beetroot, treatment with BA-3 at 0.0002% led to a yield increase of 5.8 t/ha (22.3%) compared to the control. Similarly, potato yield increased by 3.6 t/ha (15.9%) at 0.002% and by 6.8 t/ha (30.0%) at 0.0002%. Overall, the obtained results demonstrate that BA-3 effectively stimulates plant growth and development, leading to improved productivity and enhanced agronomic performance of the studied crops. - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, Application of N-(1-ethynylcyclohexyl)amide of O,O-diethyl-phosphoric acid as a growth stimulant for vegetable crops(Instituto Internacional de Ecologia (Brazil), 2025-01-01); ; ; ; This paper examines the effect of N-(1-ethynylcyclohexyl)amide O,O-diethylphosphoric acid (BA-4) on seed germination, growth and yield of the agricultural crops (carrot, beetroot, potato). As a result, seed germination in the concentrations of 0.001 and 0.0001% of BA-4 has increased by 7.0 and 19.0%, compared to the control. The results of the laboratory studies have shown that the treatment of with the BA-4 (0.0001% solution) has increased the seed germination energy by 11.0 and 17.0%, respectively. The HAU standard (0.06%) has increased the germination energy by 9.0% and germination by 10.0%. The results of the laboratory studies have shown that the use of BA-4 for treating the tubers has increased the number of awakened buds by 43.0% (0.001%) and 60.0% (0.0001%), compared to the control. When using BA-4 in the concentration of 0.001%, the carrot yield has increased by 3.5 t/ha or 15.9%, and in the concentration of 0.0001% - by 5.0 t/ha or 22.7%. When beetroot seeds were treated with the BA-4 preparation at a 0.0001% concentration, the yield increase compared to the control was 6.3 t/ha or 24.2%. The potato yield has increased from the use of BA-4 in concentration of 0.001% by 4.3 t/ha or 18.9%, compared to the control; in the concentration of 0.0001% - by 7.3 t/ha or 32.2%. The achieved results of increasing the yield of BA-4 are an effective stimulation of plant growth and development, contribute to an increase in the yield and ensure the compliance with the agricultural crop indicators.
