Abstract:
Fertilization is one of the main economic and health-promoting factors in crop cultivation. Field trials were carried out
in 2019, in the experimental field of Soybean Breeding Laboratory from Agricultural Research and Development
Station in Turda (ARDS Turda), based on a subdivided parcel design with two replications, using plots of 5 m2
. The
biological material used in this study was created at ARDS Turda, 13 semi-early, early and very early soybean
genotypes being evaluated: 7 varieties (Perla, Onix, Felix, Carla, Caro TD, Ada TD, Raluca TD) and 6 perspective lines
(T-161, T- 295, T-165, T-6126, T-6117 and T-166). Fertilization was carried out with NPK 16:16:16 complex fertilizer
applying the following doses: 150 kg/ha, 200 kg/ha, 250 kg/ha and unfertilized (Control). At the end of the growing
season the genotypes were characterized by: plant height (cm), number of pods/plant, number of seeds/plant, seeds
weight/plant (g), TKW (g), yield (kg/ha). The reported data is the average of 10 measurements. Statistical calculations
were accomplished in Excel 2013 (Microsoft, USA) highlighting differences between studied genotypes and applied
doses. The average of the seed/plant had small variations, in this year's conditions; the grain size varied between 122 g
and 162 g and the maximum yield was about 3 to/ha at the dose of 200 kg/ha complex fertilizer.
