RESEARCHES CONCERNING THE YIELD CAPACITY OF THREE HYBRIDS OF SUNFLOWER (HELIANTHUS ANNUS) IN CONDITIONS OF TIMIŞOARA PUBLISHEDMihaela Claudia Ungureanu, Valeriu Tabără
Farming future must be not only sustainable but also performing, this is accomplished through proper application of any specific technological links sunflower crop. In this link, fertilizers of any kind must take a priority role in maintaining and enhancing soil fertility to increase agricultural production. This paper aims to highlight issues concerning the importance of sunflower hybrids Clearfield type (resistant to herbicides of Group imidazolinonelor) in Romania, the role of foliar fertilizers and plant growth and development of sunflower with further implications on the quantity and quality of production optimum doses of fertilizers with nitrogen, phosphorus and potassium soil and climate conditions of Timisoara. Market presence in Romania of Limagrain for 10 years and significant results obtained by testing the potential of hybrid sunflower production behavior under extreme conditions of water stress and, together with technology you have available, argues scientific importance of these hybrids that provide farmers the best solution for placing them in culture.The study were taken three sunflower hybrids with resistance to herbicides such as imidazoline create firm Limagrain: Rimisol (approved for cultivation in Romania in 2004), and F 30008, LHA 6654. The research topic chosen, hybrids mentioned are tested against four agrofonduri: N 0 P 0 K 0 , N 60 P 60 K 60 , N 90 P 60 K 60 and N 60 P 60 K 60 + foliar fertilizer (Fertitel). Experience bifactorial type was placed in the experimental field USAMVBT. Introduction of hybrid-type culture has economic importance for agriculture Clearfield whereas monocotyledonous and dicotyledonous weed control using herbicides containing the active substance imidazolinele are eliminated 1-2 mechanical papers, which are currently very expensive. Even if a single year, the results are valuable for agricultural practice and underlines the effectiveness of foliar fertilization on the production of chemical and achenes.The results of this study are part of a doctoral program, with as theme: "Development of cultivation technology of sunflower hybrids to increase seed production and oil" under the leadership of the distinguished university professor Valeriu Tabără.
