AB  - Five Balkan paprika varieties at physiological maturity were investigated by means of Raman spectroscopy in order to discriminate the differences which stemmed from their genetic variability since the plants were grown under the same experimental conditions. The spectra were obtained using the 532 nm wavelength. In an effort to find the best classification power, several pre-processing methods were applied: 1) baseline correction, unit vector normalization; 2) baseline correction, unit vector normalization and first Savitzky-Golay derivative; 3) baseline correction, unit vector normalization and second Savitzky-Golay derivative; 4) baseline correction, unit 
vector normalization and third Savitzky-Golay derivative. All of the pre-processing methods were followed by 
making PCA-LDA (Principal Component Analysis-Linear Discriminant Analysis), QDA (Quadratic Discriminant 
Analysis), and PLS-DA (Partial Least Square - Discriminant Analysis) classification models. QDA showed the best discrimination power (83.87–100% and 89.47–100% for the training and the test data, respectively), then PCA-LDA (0.00–100 and 0.00–100% for the training and the test data, respectively) and PLS-DA (19.35–100% and 0.00–100.00% for the training and the test data, respectively). The results pointed out the applicability of 
chemometric modeling associated with Raman spectroscopy in the assessment of nutritionally similar samples, 
such as the studied red paprika varieties.

AB  - Soybean crop production in Serbia involves seed inoculation by N-fixing bacteria just before sowing time. The main objective of the current work was to assess the impact of the genotype and inoculation on range of morphological and yield traits of soybean (Glycine max L. Merrill), as well as the total protein content. The experiment was conducted on chernozem soil, where soybean was previously grown. The six local varieties were used, where each variety was sown, in three replicates for both inoculated and non-inoculated treatment. The following morphological traits were analysed: the plant height, number of lateral branches, distance to the first pod, number of pods per plant, pods (containing seeds) weight per plant, seed weight per plant, and the total grain yield. The total protein content in seeds was determined by standard analytical method, while subtle differences in qualitative protein composition were assessed using Raman spectroscopy. The total protein content varied from 39.6 to 42.15 %. Performance of inoculation resulted in an increase of the plant height and the distance to the first pod, although not in all tested varieties. The highest and the lowest plant height values were observed for non-inoculated variety Dana (59.23cm) and Sava (80.03cm), respectively. The effect of genotype was much more expressed causing differences in almost all tested characters, except for the total protein content. However, Raman spectroscopy analyses revealed distinct discrimination among surveyed varieties, and differences between inoculated and non-inoculated plants in qualitative composition of seed proteins.
AB  - Proizvodnja soje u Srbiji uključuje inokulaciju setvenog materijala azotofiksirajućim bakterijama pre setve. Glavni cilj ovog rada je procena uticaja genotipa i inolulacije na morofoške parametre i prinos soje (Glycine max L. Merrill) kao i na sadržaj ukupnih proteina. Eksperiment je sproveden na zemljištu tipa černozem na kojem je prethodno uzgajana soja. Za setvu je korišćeno šest domaćih sorti soje, gde je svaka sorta sejana u tri ponavljanja sa dva tretmana (inokulisano i neinokulisano seme) i praćeni su sledeći morfološki parametri: visina biljke, broj bočnih grana, broj spratova, broj mahuna po biljci, masa mahuna sa semenom po biljci, masa semena po biljci bez mahune i ukupni prinos. Sadržaj ukunih proteina u semenu određen je standardnom analitičkom metodom dok su fine razlike u kvalitativnim osobinama proteina procenjene Ramanovom spektroskopijom. Sadržaj ukunih proteina bio je uniforman i kretao se do 39.6-42.15 %. Inokulacija je dovela do povećanja visine biljke i visina biljke do prve mahune. Najveća i najmanja prosečna visina biljke je uočena kod neinokulisanih sorti Dana (59,23 cm) i Sava (80,03 cm), respektivno. Efekat sorte je bio izraženiji i izazvao je efekat kod svih parametara osim sadržaja ukupnih proteina. Međutim, primena Ramanove spektroskopije je pokazala jasne razlike između ispitivanih sorti u kao i razlike između inokulisanih i neinokulisanih sorti u pogledu kvalitativnog sastava proteina semena.
