Economic and biological characteristics and productivity analysis of sunflower hybrids

Evaluation of the biological characteristics of sunflower hybrids and their potential to improve the qualities of the plant under study that are useful for agricultural development is considered relevant. The research aims to carefully and in-depth evaluate the biological characteristics of sunflower hybrids to obtain information on the possibility of improving the qualities of the plant under study that is useful for agricultural development. During the experiment, the properties of such sunflower hybrids as Ukrainian F1 (control sample), P62LL109 Pioneer (Classic), LG5377 (Limagrain), ES Bella (Euralis Semans) and NK Rocky (Syngenta) were investigated. Each of these plants is listed in the State Register of Plant Varieties of Ukraine. The methods used in this research work include the production method, weighing and measuring, visual, laboratory and chemical, and mathematical. It was determined that the best indicators of productivity and economic characteristics are observed in three hybrid species, namely Ukrainian F1 (the best morphological characteristics, the highest weight of 1000 seeds, and hulling level), NK Rocky (Syngenta) (the highest percentage of fat and oil yield per 1 ha) and P62LL109 (Pioneer) (the highest weight of seeds per basket and bulk weight, the lowest hulling level, the highest yield). This may be useful for agricultural enterprises that may be interested in growing new sunflower hybrids with improved productivity and economic characteristics. The results of the study may become an impetus for further research of existing and creation of new sunflower hybrids that will be most useful for agricultural development
