Sorte soje mogu se razlikovati po morfoloŔkim osobinama, dužini vegetacionog
perioda, prinosu i kvalitetu zrna. Cilj ovoga rada je sagledavanje prinosa, sadržaja
proteina i ulja, kao i prinosa proteina i ulja po jedinici povrŔine NS sorti soje u 2020.
godini na lokalitetu Rimski Å anÄevi. Sorta soje NS Fantast ostvarila je najviÅ”i prinos
zrna (4402 kg ha-1). NajviŔi prinos proteina po jedinici povrŔine ostavrila je sorta soje
NS Kolos (1756 kg ha-1). Sorta NS KaÄa imala je najviÅ”i sadržaj proteina (46,21),
sorta NS Atlas najviŔi sadržaj ulja (22,73%), dok je najviŔi prinos ulja po jedinici
povrŔine ostvaren sa sortom soje NS Fantast (961 kg ha-1) i NS Hogar (954 kg ha-1).Soybean varieties can vary accordind to morphological characteristics, vegetation
period lenght, yield and grain quality. The aim of this paper is to analyze the yield,
protein and oil content, as well as protein and oil yield per unit area of NS soybean
varieties in 2020 at the Rimski Å anÄevi locality. The NS Fantast soybean cultivar had
the greatest grain yield (4402 kg ha-1). The NS Kolos cultivar had the greatest protein
yield per unit area (1756 kg ha-1). The NS KaÄa cultivar had the greatest protein
content (46.21), the NS Atlas cultivar had the greatest oil content ( 22.73%), while
the greatest oil yield per unit area was achieved with the NS Fantast soybean variety
(961 kg ha-1), and NS Hogar variety (954 kg ha-1)
Uticaj meÄurednog razmaka na broj plodnih nodija kod soje u uslovima navodnjavanja
Three row spacings and three soybean cultivars were examined under irrigation conditions during a two-year study. The objective was to determine the influence of row spacing changes on fertile node number of soybean. The analysis of variance was performed on data following a two-factorial split-plot design , with cultivar and row spacing as main plot and subplot factors, respectively (Hadzivukovic 1991). The number of nodes with pods present was significantly dependent on maturity group. The late cultivar was determined to have a significantly greater number of nodes with pods (1.95 to 2.78), as compared to the early and medium maturity cultivars. An increase in row spacing resulted in an increasing number of fertility nodes (12.05, 12.37, and 13.51). A positive correlation was established between yield per plant and fertile node number.U dvogodiÅ”njem istraživanju ispitivana su tri meÄuredna razmaka i tri sorte soje razliÄite grupe zrenja u uslovima navodnjavanja. Cilj je bio da se ustanovi u kojoj meri promena meÄurednog razmaka utiÄe na broj plodnih nodija kod soje. Podaci su obraÄeni analizom varijanse po metodi dvofaktorijalnog split - plot ogleda, gde su faktori ispitivanja: sorta (velika parcela) i meÄuredni razmak (podparcela) (HadživukoviÄ 1991). Broj nodija s mahunama bio je znaÄajno zavisan od grupe zrenja. Kasana sorta, imala je znaÄajno veÄi broj nodija s mahunama (1.95 do 2.78) u odnosu na ranu i srednjestasnu sortu. PoveÄanjem meÄurednog razmaka setve dolazilo je do poveÄanja nodija sa mahunama (12.05, 12.37, 13.51). UtvrÄena je pozitivna korelacija izmeÄu prinosa po biljci i broja plodnih nodija
Dužina peteljki sirka metlaÅ”a pri razliÄitom sklopu biljaka
Bromcorn fiber length is determined by measuring the distance between the point at which the fibers start to branch out and the tip of at least two thirds of all the fibers present in a given panicle. This is a very important morphological trait, as it determines the success of the panicle harvest. A two-year investigation was carried out in order to determine the influence of different stand densities on fiber length levels in two broomcorn genotypes. Two row-to-row spacing (50 and 70 cm) and six plant-to- plant ones (5, 9, 13, 17, 21, and 25 cm) were studied. Fiber length was the smallest (42.6 and 45.2 cm) with the highest stand densities, and it increased with increasing plant growing space (63.7 cm and 71.0 cm). .Dužina peteljki sirkovih metlica predstavlja rastojanje izmeÄu taÄke grananja peteljki i mesta gde se nalazi vrh najmanje 2/3 od ukupnog broja peteljki. Ovo je veoma bitna morfoloÅ”ka osobina biljaka sirka metlaÅ”a, od koje zavisi uspeÅ”nost žetve sirkovih metlica. U cilju sagledavanja promene dužine peteljki sirkovih metlica u zavisnosti od razliÄitog sklopa biljaka, izvrÅ”ena su dvogodiÅ”nja istraživanja sa dva genotipa sirka metlaÅ”a. Ispitivana su dva meÄuredna razmaka od 50 i 70 cm i Å”est razliÄitih razmaka biljaka u redu, (5, 9, 13, 17, 21 i 25 cm). Dužina peteljki bila je najmanja pri najguÅ”Äim sklopovima 42,59 i 45,22 cm, dok je sa poveÄanjem vegetacionog prostora dužina peteljki bila sve veÄa - 63,72 i 71,04 cm
CONTROL OF GENETIC IDENTITY BY PROTEIN ELECTROPHORESIS IN VARIETAL REPRODUCTION OF WHEAT
Održanje i kontrola genetske ÄistoÄe, odnosno genetskog identiteta, jedan je od krajnjih ciljeva sjemenarstva nakon priznavanja neke sorte pÅ”enice. Primjena pozitivne i negativne selekcije, na razini fenotipa pri sortnoj reprodukciji pÅ”enice, omoguÄila je sortnu ÄistoÄu od 99 i 100% u usjevima svih sjemenskih kategorija. U cilju ispitivanja genetske identiÄnosti, u ovom su radu analizirane
rezervne bjelaÄevine pÅ”enice ā glijadini, koji su metodom poliakrilne gel elektroforeze razdvojeni na veliki broj frakcija koje pokazuju visoku heterogenost. Od analiziranih sorti pÅ”enice jedino je sorta PKB Rodika imala genetsku ÄistoÄu od 100% za sve kategorije sjemena. Sorta PKB Kristina je imala genetsku ÄistoÄu od 99% za kategoriju predosnovno sjeme, a sorta BG Merkur 99% genetske ÄistoÄe za kategoriju ā sjeme prve generacije C1. Elektroforeza bjelanÄevina pokazala je da postoji divergentnost izmeÄu ispitivanih sorti pÅ”enice po sastavu komponenti glijadinske frakcije, dok unutar sorti postoji ujednaÄenost.Maintenance and control of genetic purity and genetic identity is one of the ultimate goals in seed production after the recognition of some varieties of wheat. The application of positive and negative selection at the phenotypic level in varietal reproduction of wheat, enabled 99 and 100% of varietal purity in crops of all seed categories. In order to study the genetic identity, in this paper the reserve proteins of wheat ā gliadins were analyzed. They were separated by polyacrylic gel electrophoresis into numerous components that showed great heterogeneity. Of all the analyzed wheat varieties, only PKB Rodika variety had the genetic purity of 100% in all categories of seed. PKB Kristina had the genetic purity of 99% in the pre-basic seed category and the variety BG Merkur had genetic purity of 99% in the seed of first generation ā C1. Protein electrophoresis showed there was the divergence among the varieties of wheat in its composition of gliadin fractions, while there was uniformity among defferent varietal reproductions within each variety
Influence of nickel in soil
The objective of this investigation has been to study consequences of soil pollution with nickel in five locations in the municipalities of Sremska Kamenica, Ledinci and Beocin. The analysis of soil samples collected in the five locations has shown that the percentage of nickel differed from location to location. Nickel contamination was registered in 60% of the analyzed sites. A possible nickel polluter in this area is the cement factory in Beocin (CFB). The intensity of nickel contamination of soil decreased progressively with the distance of the sampling sites from the cement factory in Beocin
Importance of microbiological fertilizer used in soybean production: Agronomical and biological aspects
Inoculation is the best way to ensure good nodulation with the proper strain of nitrogen-fixing bacteria for increased yield in an environmentally safe manner. This investigation was conducted on three-year experiment which was set up in four replications with three-crop rotation (maize-soybean-wheat) at experimental field of the Institute of Field and Vegetable Crops, Novi Sad, Serbia. Effects of application of microbiological fertilizer (with nitrogen-fixing bacteria Bradyrhizobium japonicum) on root mass, number and mass of nodes per plant, soil biogeneity (number of ammonifiers, Azotobacter, actinomycetes), as well as the effect on soybean yield were studied. Obtained results indicated positive impact of inoculation on nitrogen fixation parameters. The higher amounts of mineral nitrogen had negative impact on atmospheric nitrogen fixation, that is, by increasing preplanting mineral nitrogen amount in the soil by 1 kg, the amount of calculated nitrogen from the air was decreased by 1.72 kg. Increasing abundance of studied microorganisms in the rhizosphere, as well as soybean yield using microbiological fertilizer was stimulated by plowing under crop residues. The impact of meteorogical conditions on the effects of inoclutaion was very significant
