Knowledge of genetic traits that affect yield and chemical composition of soybean grain is vital for the organization of an effective soybean breeding program. Two-year trials (2009-2010) were carried out at the Rimski Sancevi Experiment Field of the Institute of Field and Vegetable Crops in three replications. We assessed the impact of foliar fertilization with a complex liquid fertilizer that combined macroelements (N, P, K - 12:4:6, respectively) and microelements (Fe, Mn, Cu, B, Zn) on yield and grain chemical compositions of NS soybean cultivars of different maturity groups. The following traits were monitored: 1000-grain weight (g), soybean grain yield (kg/ha), and total protein and oil contents and protein and oil yield in soybean grain. All traits varied significantly depending on variety and year. On average, all cultivars had higher yield and 1000-grain weight in the variant with foliar fertilization than in the control. The highest yield in the control variant was achieved by the cultivar Victoria (5273 kg ha-1 in 2009, while the highest yield in the variant with foliar fertilization was achieved by the cultivar Tea (5333 kg ha-1) in 2010. The average weight of 1000 grains was significantly higher in 2010 (161.2 g) than in 2009 (132.4 g). The lowest average 1000-grain weight was registered for the cultivar Galina (140 g). The cultivar Victoria had the highest protein content in the control variant, while the cultivar Tea had the highest oil content (21.73%). In the variant of foliar fertilization, the cultivar Tea had significantly higher contents of proteins and oil than the other tested varieties. The values of the coefficient of correlation between the studied traits in the variant of foliar fertilization were similar to the values in the control variant. The oil content was significantly and negatively correlated with 1000-grain weight (r=-0.86**, r=-0.80**) and negatively correlated with protein content in soybean (r=-0.42, r=-0.04) in both the control variant and the variant with foliar fertilization. The yield was negatively correlated with protein content (r=-0.36, r=-0.05) in the control variant and the variant with foliar fertilization. The obtained results indicate that the yield, protein and oil content in soybean is a cultivar characteristic, but it is also strongly affected by the environment and affected by the foliar fertilization.

Research was conducted to assess metal contamination of soils and fruits and evaluate potential human health risks. Heavy metal concentrations (Fe, Mn, Cu, Zn, Cd and Pb) in plum orchard soils were below maximum permissible concentration. I geo showed that soils were uncontaminated (I geo <0 for Fe and Mn) and uncontaminated to moderately contaminated (I geo for Cu, Zn, Pb and Cd ranged from 1.20-0.57, 1.32-0.98, 2.97-0.88 and 1.26-0.58, respectively). Fruit Zn, Cu, Mn, Pb and Cd concentrations were within maximum permissible concentration in foods in Serbia. Only Fe levels were above maximum permissible concentration at most locations. The soil-to-fruit transfer factor (TF) showed large differences between metals. TF for Cd and Pb was 0.0, for Mn 0.007-0.030 and for Zn 0.04-0.09, indicating no potential risk to human health, whereas TF for Fe and Cu was high, i.e. 0.30-1.51 and 0.33-1.69, respectively, suggesting that plum can accumulate Fe and Cu. © 2014 Springer International Publishing Switzerland.

This paper deals with interrelationship between grain yield and some physiological parameters of wheat plant nitrogen nutrition efficiency as well as interrelationships between these parameters and some yield related traits (biological yield, grain harvest index). The aim of such investigation is to affirm possibilities of using physiological parameters of wheat plant nitrogen nutrition efficiency as criterions in breeding on its grain yield. The investigation, conducted as three years field trials, included 30 wheat cultivars and perspective lines. There were studied: nitrogen content in the above - ground part of plant at anthesis, in grain, in straw and total nitrogen content at maturity, nitrogen harvest index, nitrogen reutilization, post - anthesis nitrogen accumulation and physiological efficiency of nitrogen. The positive and statistically high significant relationships between nitrogen content in the above - ground part of plant at anthesis, in grain and in straw, total nitrogen content at maturity, nitrogen reutilization and post - anthesis accumulation as physiological parameters and grain yield were registered in investigated material. Most of listed parameters, important by grain yield aspect, can be studied easily and measured before wheat vegetative period ends. The investigated parameters can be recommended as criterions for selecting of parental pairs and evaluating progeny in breeding of wheat on grain yield, considering to their determined interrelationships and their measurability.

Considering the very important role of nitrogen in plant life cycle, parameters of plant nitrogen nutrition efficiency represent a group of physiological traits suitable to contemporary wheat breeding aims. Therefore, the objectives of the study were to estimate variability of nitrogen nutrition efficiency indicators and to estimate their heritability in wheat. The experiment included 30 wheat cultivars and experimental lines, originating from Serbia: Small Grains Research Center and Institute of Field and Vegetable Crops, Novi Sad. The variability and broad - sense heritability of total nitrogen accumulation (ANt) at maturity, grain harvest index (GHI) and physiological efficiency of nitrogen (PEN) were analysed. The years when the researches were carried out had a highly significant effect on all tested indicators, as well as genotype and interaction year x genotype. Total nitrogen accumulation in mature plant was the most variable indicator (Cv 13.91%), while lower variability was registered for nitrogen harvest index and physiological efficiency of nitrogen (5.81% and 5.59% respectively). NHI heritability was lower (0.52) compared to the ANt and PEN (0.66 and 0.69, respectively). On the other hand, heritability of ANt and PEN were almost the same, but PEN was more repeatable than the ANt. Source

The uplands and highlands in Western Serbia are the most important oat production regions in Serbia. An experiment was conducted on a Luvisol soil in the Mt. Radočelo region (southwestern Serbia) in order to evaluate the effect of soil ameliorative operations (liming and humification) and fertilization on grain yield, test weight, 1000-grain weight and grain protein content in oat. The combined use of NPK fertilizers (120 kg N ha-1, 80 kg P2O5 ha-1, 80 kg K2O ha-1), lime (5 t ha-1) and manure (30 t ha-1) provided an optimum supply of major nutrients, resulting in maximum grain yield (5.443 t ha-1). The combined use of NPK, lime and manure induced a significant increase in test weight and protein content, and a moderate increase in 1000-grain weight. NPK fertilization increased grain yield and test weight, but showed no effect on 1000-grain weight and grain protein content. Nitrogen application resulted in a significant but lower increase in grain yield and quality, which was not likely to provide a significant economic benefit. The combined use of chemical ameliorative operations (liming and humification) and fertilization, especially with adequate rates of nitrogen and phosphorus, facilitate the optimization of the yield and quality of grain having a high market value.
