Efficiency of herbicide treatment for productivity of the maize hybrid ‘Zernogradsky 354 MV’

The current paper has presented the study results of application herbicides ‘Meister Power MD’; ‘Remus VDG’; ‘Dianat, VR’; ‘Sekator Turbo, MD’ as elements maize cultivation technology in southern part Rostov region. Field trials were carried out 2019–2021. object was hybrid ‘Zernogradsky 354MV’, (included State List Breeding Achievements 6th (North Caucasian) region 2010). purpose an economic and agronomic estimation when cultivating for grain. soil experimental plot ordinary calcareous heavy loamy blackearth (chernozem) on loess-like loams. content humus arable layer 3.36 %, pH 7.0, P 2 O 5 24.4; K 360 mg/kg soil. hydrothermal coefficient during a vegetation period 0.62 2019; 0.70 2020; 0.86 2021. Thus, years, humidification conditions very arid. As result conducted study, it revealed that had positive effect phytosanitary sowing. weediness reduced 95.3–97.1 %. grain productivity increase due to significant amounted 0.28– 0.53 t/ha or 17.4–24.2 % compared with control. cost herbicide Power, (5670 rubles per hectare norm) did not contribute its high payback. maximum payback identified variant complex ‘Remus, VDG’ + BP’ 5.50 rubles/rub. also cost-effective 5.36 5.45 rubles/rub., respectively.
