Abstract

Results of researches aimed at studying and determining the complex influence of seeding rates and row spacing on productivity formation of spring rape variety Sirius and hybrid Ozorno in conditions Right Bank Forest-Steppe of Ukraine are presented, as well was determinate relationships between investigated parameters and structural elements of the culture.Research was conducted during 2015-2017 under conditions of stationary field crop rotation of Plant Growing Department PE NULES of Ukraine "Agronomic Experimental Station". Soils - is typical (deep) low-humus blacksoil, rough-pew-loamy by mechanical composition. Research was conducted with variety Sirius and hybrid Ozorno. Sowing was carried out with seeder Klen SZ-3.6, with forming different widths of rows: 12.5, 15.0, 25.0 and 30.0 cm with seeding rates of varieties and hybrids 0.8, 1.0, 1.2 and 1.4 million similar seed per hectare. As a result of our researches, it has been established that in conditions Right Bank Forest-Steppe of Ukraine the optimum width of row spacing for variety Sirius is 15.0 cm with seeding rate 1.2 million seeds/ha, for hybrid Ozorno respectively 12.5 cm and 0,8 million s/ha.
