Abstract. In recent years, Romanian farmers had the opportunity to use in the culture the most modern creations of the researches from genetics and plant breeding domains, but also from the field of plant protection. In the paper is presented the behavior of some sunflower hybrids, newly introduced into the culture in Romania, under the conditions of Muntenia Plain. The experience was conducted in the farm I.I. Visan Daniela Elena, locality Slobozia Noua, Ialomita County. There were tested under field conditions two semi-early sunflower hybrids, existing from a short time in The Official Catalogue of the culture plants from Romania, on a typical chernozem soil type. In the paper is presented the culture technology applied to both sunflower hybrids, with reference to preliminary plant, administration of fertilizers, the applied soil tillage. Also, it was tested in the field a variant of technology concerning the culture protection against diseases and pests. Together with these elements, the authors tested under field conditions a variant of technology regarding the control of weeds.In order to accentuate the behavior of the two hybrids, we effectuated the following determinations: plants height, head diameter, weight of the whole plants, weight of heads with seeds, weight of heads without seeds, weight of seeds from the head, weight of 1,000 kernels. Considering that the surface cultivated with sunflower in Romania in 2013 was over 1 million hectares, and the average yield on the country was 2,000.5 kg/ha, the modern technology applied and the hybrids that are used may constitute a starting point for the farmers who want to implement in the production the modern technologies and sunflower hybrids tested in the present paperwork.
Key words: sunflower hybrids, modern technologies, semi-early hybrid
