Sunflower (Helianthus annuus L.) is one of the cultivated species with great use potential, which leads to as need of finding permanent solutions for the efficient valorisation of this plant as a source of lipids, proteins, and carbohydrates, especially in the context of the continuous diversification of energy sources and raw materials for the industrial and agricultural sectors. The paper analyses the reaction of Helianthus annuus L. genotypes to the soil, temperature, and humidity conditions of the Crișurilor Plain, in conjunction with the cultivation technology recommended for this species. The results were obtained during the years 2021 - 2022, the experiment being single-factor, in four replicates, with five established hybrids. The sunflower genotypes used as experimental variants were as follows: V1 - Performer; V2 - Ilinca 115; V3 - Inkasun IR; V4 - Bravo SU; V5 – Florasun. Among the parameters analysed in the tested hybrids, we mention: vegetation period, plant height, capitulum diameter, the mass of 1000 achenes, hectolitre mass of achenes, achene production, as well as percentage content of achenes in lipids, proteins, and carbohydrates. The results obtained were then interpreted in terms of economic efficiency, recommending the Crișurilor Plain as a suitable region for growing the tested hybrids.
