The impact of progressive cultivation technology on the productivity of coriander on chernozems of the Lower Volga region

The data of long-term research on increasing the yield and quality coriander seeds by selecting most productive varieties improving basic techniques its cultivation technology are presented. It has been established that is Akkord cultivar, which we have bred released. Biochemical, biological agrotechnical features studied. High laboratory germination was revealed (90.1%), field varied from 88.5 - 93.5% depending weather conditions. Low growth rates were at beginning before branching phase. By budding flowering phase, formation leaf surface (46.2 thousand m 2 /ha) accumulation aboveground green (26.2 t/ha) dry (3.1 biomass reach their peak levels. maximum achieved deep plowing to a depth 25-27 cm for variety 1.41 t/ha versus 1.20 1.14 Alekseevskii 413 Svetlyi cultivars. greatest amount essential oil contained in all studied browning phase central umbels smallest one period filling ripening seeds. On average, over years (2015-2018), highest (1.41 obtained with skip-row (30 cm) planting seeding rate 2.0 million viable per hectare. With such method, content (1.20%) fat (20.1%) provided, 15.5-24.7% higher compared both lower (0,5 germinating 1 ha) (2.5 ha). same pattern observed other sowing methods – line wide-row planting.
