RESEARCHES ON OPTIMIZING THE CULTURE TECHNOLOGY IN SUNFLOWER

The approached issues covered research objectives aimed at optimizing the culture technology in order to achieve maximum and constant sunflower yield, in the soil and climate conditions of southern Romania, also pursuing the economic efficiency and environment protection. Research were performed in the experimental field Systems of Sustainable Agriculture and Crops Fertilization (SSA-CF) not irrigated version, in the framework of NARDI Fundulea, pursuing the following parameters: hybrids, fertilization and plants density The experimental diagram is three factorial type of form 3 x 3 x 2, managed according to the subdivided parcels method, in three repetitions.The total testing area was of 11,760m2. In order to organize the experiment it was used biological material consisting of three sunflower hybrids. Crop management was performed in optimal conditions of technology specific to the culture area, the studied genotypes consisting of: Performer (test check – semi-late hybrid), Barolo RO (semi-late hybrid), and PR64A89 (semi-late hybrid)
