By the correct appliance of all technological links specific to the sunflower culture, the agriculture becomes more sustainable and advanced. Like any culture plant, the spectacular progresses achieved by the firm Limagrain in Romania, in the last years, impose the thoroughly study of the main features of the Clearfield sunflower hybrids and of their behavior under the differential influence of the chemical and foliar fertilization, with their ulterior implications on the morphological particularities of the achenes. The sunflower hybrids with genetic resistance to certain herbicides like imidazoline or sulphuran-urea herbicides which can be applied post-emerging contribute both to increasing of the yields per hectare and to enhancement of the sunflower efficiency in the farms.
