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.

The aim of this study was to determine the concentrations of 11 metals in the soil of asbestos tailings in Stragari, Serbia, and in the selected plant species that grow on it, to determine the ability of the plant species in accumulation and tolerance of researched metals. Concentrations of elements researched in the soil had this order: Mg > Fe > Ca > Ni > Cr > Mn > Co > Zn > Pb > Cu > Cd. Concentrations of the metals in plants was variable, dependent on the plant species and types of metals, and graded in the order: Mg > Ca > Fe > Ni > Mn > Cr > Zn > Co > > Pb > Cu > Cd. The concentrations of Ni and Cr in the investigated soil were above remediation values, as well as the maximum allowable concentration of substances in the soil according to regulation of Republic of Serbia, and the concentration of Cd and Co were above limit values for a given metals in the soil. The metal uptake does not necessarily correlate with metal content in the soil. Metal uptake by plants depends on the bioavailability of the metal in soils, which in turn depends on the retention time of the metal, as well as the interaction with other elements and substances. However, the most Mg, Fe, Mn, Pb, Cd, Co and Cr were found in species Sanguisorba minor, Ca and Cu in Eryngium serbicum, Ni in Alyssum murale, and Zn in Euphorbia cyparissias. In the Euphorbia cyparissias, it were determined the biological absorption coefficients greater than 1 for Zn and Cu, and in the species Eryngium serbicum and Sanguisorba minor greater than 2 for Cu. The results of this study emphasize the tolerance of several metal by species Sanguisorba minor, present the ability of Euphorbia cyparissias in accumulation of Zn and Cu, as well as of Eryngium serbicum and Sanguisorba minor in accumulation of Cu. Obtained results present the momentary picture of investigated locality, open a lot of questions connected with relationships soil/plant, contents of elements in both systems, their interactions and influences and represented the base for further research. © 2015, Association of Chemists and Chemical Engineers of Serbia.

Cognition of chemical composition and nutritive values of triticale grain as well as the effect of its application in non-ruminant animal nutrition were pointed out in this paper. There is a high level of proteins in the grain of triticale (2 to 3% more than wheat and 4% more than rye), with very beneficial amino acid composition, and is the reason for its usage in domestic animals nutrition. Nowadays, people are of the opinion that triticale is one of potential plant species with the brightest perspective in the production of food for domestic animals. Considering the increased production of triticale, some detail researching of its nutritional value is necessary due to the required evaluation of the role and significance in domestic animal nutrition based on triticale. Due to intensive plant breeding programs, there are new varieties of triticale in the market, distinctive by the higher yield and wide range of desired traits. As a result of this, triticale is becoming very attractive and is occupying larger portions of arable land. These review will show if there are some advantages of triticale compared to other cereals and how large the frame of these advantages is, as well as how it will affect the further spreading of triticale on arable land. © 2011 Academic Journals.

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.

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.

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.

About 60% of wheat fields in Central Serbia have a soil pH below 5.5. Therefore, increasing and maintaining crop yields require periodic use of soil amendment practices (liming, phosphorus treatment and humification), along with fertilization. This study was conducted over a period of five years (2007-2011) on a pseudogley soil to evaluate the effect of different fertilization methods and liming on grain yield, yield components and grain quality in three winter wheat (Triticum aestivum L.) cultivars. Results showed a significant effect of weather conditions on grain yield and quality in winter wheat. The combined use of NPK fertilizers (120 kg N ha-1, 100 kg P2O5 ha-1, 60 kg K2O ha-1), lime (5 t ha-1 CaCO3) and manure (20 t ha-1) led to a drastic reduction in Al levels in the grain (by over 10 mg kg-1), and positively affected grain yield and yield components in winter wheat. Less favorable agro-meteorological conditions and combined organic and mineral fertilization positively affected grain protein concentration in all winter wheat cultivars analyzed. © 2015, National Agricultural Research and Development Institute Fundulea.

Study of fertilization effects were conducted in a stationary type of field trial, on a degrading vertisol soil with low pH. Eight variants of mineral nutrition (NK, NP1, NP2, NP3, NP1K, NP2K and NP3K) and untreated control (without nutrition) were tested in the experiment. The rates of nitrogen application were 80 kg N ha-1, and they were applied either individually or in combination with three phosphorus rates and the potassium fertilizer. The highest grain yields under mineral nutrition involving a combination of three mineral elements were: N, P and K (80 kg N ha-1, 60 kg P2O5 ha-1, 60 kg K2O ha-1), and under NP2K treatment at a rate of 80 kg N ha-1, 80 kg P2O5 ha-1 and 60 kg K2O ha-1. Based on the analysis of variance, it can be concluded that there were highly significant differences in grains yield among years of investigation and highly significant differences at 1000-grain weight and grain test weight.

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.
