RESEARCH ON THE INFLUENCE OF CHEMICAL AND FOLIAR FERTILIZERS ON THE CONTENT OF OIL IN A THREE ACHENES SUNFLOWER HYBRIDS IN TERMS OF TIMISOARA PUBLISHEDMihaela Claudia Ungureanu, Valeriu Tabără
Market presence in Romania for 10 years Limagrain company and the significant results obtained by testing the potential of hybrid sunflower production, and along with the technology you have available, scientifically argues that culture is placed in the best solution for farmers. The correct application of any specific links sunflower crop, agriculture becomes more sustainable and performance. Sunflower is cultivated for its seeds are used as feedstock in the cooking oil industry, providing 9% of the raw materials processed annually in the world oil industry and 12% of world production of oil. In Romania, became the third sunflower crop in area planted. The importance of this plant is given by oil that it produces seed oil quality in human nutrition, urged consumers. In the present study are highlighted aspects of the importance of sunflower hybrids in Romania Clearfield type, role and foliar fertilizers on growth and development of sunflower plants with subsequent implications on the production of seeds and oil content in pedoclimatic conditions of Timisoara. The study were taken three sunflower hybrids with resistance to herbicides such as imidazoline create by the company Limagrain: Rimisol (approved for cultivation in Romania in 2004), F30008 and Hidalgo. The research topic chosen, the hybrids mentioned are tested against four agro-backgrounds: N0P0K0, N60P60K60, N90P60K60 and N60P60K60 + foliar fertilizer (Fertitel). Bifactorial type experience in the experimental field was located within USAMVB Timişoara. Under the influence of fertilization, increasing oil production hybrids studied. Thus from the agro unfertilized, fertilized with the agro 60kg/ha nitrogen, phosphorus and potassium, oil production increased by 406 kg / ha, the increase was statistically highly significant. Fertitel foliar fertilization with a balanced agrofond fertilized with nitrogen, phosphorus and potassium significantly influence oil production, resulting in a yield of 2230 kg / ha to 1722 kg / ha as is done on the agro control, increase of 508 kg / ha being provided as very significant statistically. Production of oil / ha of producing achenes and oil content, the same level of fertilization (N60P60K0) ranged from 2135 kg / ha to 2259 kg Hidalgo and hybrid / hybrid F 30008 ha to 1991 kg / ha, oil production achieved the control hybrid Rimisol. Regarding agro-background is found that fertilization significantly influence oil content in seed hybrids studied. The oil content of seeds obtained from fertilized agro-backgrounds N60P60K60 N90P60K6 that is 47% compared to only 40% as containing the seeds obtained from unfertilized control agro-background.
