Efficiency of grain sorghum cultivation for various crop care measures

Purpose. To improve the technology of grain sorghum cultivation by detecting influence microfertilizers and plant growth regulators on its productivity.
 Methods. The research was conducted at field Bila Tserkva National Agrarian University, which is located in zone unstable humidification Right-Bank Forest-Steppe, years 2019–2021. Grain hybrids ‘Brigga’ ‘Yutami’ were used for experiment.
 Results. experimental results show that highest production costs amounted to UAH 5,149.9 a yield 7.88 t/ha, while 6.65 t/ha resulted 5,067.1. hybrid had (7.48 t/ha) treatment with use Alpha-Grow-Extra microfertilizer (2 l/ha, first 5-leaf stage, second 9-leaf third stage throwing panicles) combination regulator Stimpo (20 ml/g, stage). minimum difference maximum 8.89 8.88 treatments l/ha) ml/ha) Regoplant (50 regulators.
 Conclusions. profit growing 39,638 per hectare foliar fertilization using regulator. In case ‘Yutami’, Alfa-Grow-Extra regulator, 48,550 hectare, similar application Regoplant, 48,622 hectare.
