Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 104, Issue
Abstract
The article is devoted to the results of the investigations conducted in 2014–2016 under the steppe conditions of Mykolaiv region on typical black low humus soils. The investigations were aimed to study the influence of sowing dates and row spacing of sunflower hybrids Forward, Jason, PR64F50, PR64A15, PR64A89 on plant biometric indices. The results of the research show that sunflower biometric indices depend on variety type characteristics, sowing dates and row spacing. At the same time, we did not observe clear dynamics in indicators. There was a substantial decrease in biometric indices of sunflower hybrids under late sowing time compared to early and recommended dates.
