This article deals with development of agrocenosis productivity in spring soft wheat varieties. Current research is aimed at examining the spects of agrocenosis productivity and the reliable cultivation technology to obtain high dry matter synthesis. The article points out plant safety, survival, and the growing season, depending on the cultivation technologies applied. It was noted that mineral fertilizers application at sowing had no effect on germination rates. Regardless of the technology used, high plant survival was observed. Plant mortality during the growing season ranged from 2% to 6%. It was recorded that, with a 95% probability, plant survival is independent of the chosen cultivation technology. As a result, the spring soft wheat varieties (Arhat, Ekada 253, Ekada 279, Ekada 282, Pandora, and Sensei) form a productive agrocenosis with intensive technologies, including: common methods of pre-sowing soil cultivation; complete plant protection: seed treatment (Vial Trio – 10 l/t), treatment with a herbicide + fungicide mixture (Balerina Super, SE – 0.5 l/ha + Kolosal PRO, KME – 0.4 l/ha), and treatment with a fungicide + insecticide mixture (Kolosal PRO, KME – 0.4 l/ha + Borey, SK – 0.1 l/ha); mineral fertilizers application according to N16 P16 K16 at sowing + N68 as a top-dressing. This technology provides more comfortable conditions for plant growth and development, which prolongs the growing season and photosynthetic activity to obtain extra dry matter synthesis.
Keywords: wheat, germination, seeds, plant safety, plant stability, dry matter.
