Eggs are a unique product and serve to feed people of all ages. They have a very high nutritional value, because they contain a relatively high percentage of proteins, minerals, vitamins. Some researchers emphasize that eggs, in addition to high nutritional value, provide many health benefits, and have immunostimulating, therapeutic and functional properties, which makes them universal products. Although the number of eggs (load capacity), food conversion and mortality are still considered to be the main indicators for calculating the production index or the economic performance of egg production, producers must increasingly take into account the quality of eggs in order to meet consumer demand. This means that special attention should be paid to egg structure (proportion and yield of shell, white and yolk), which we touched on in this paper.

The aim of the study was to evaluate the occurrence and development of weed species as actual weed infestation of maize in sustainable farming systems. The specific goals of the study were to assess the dynamics of occurrence of each weed species in integrated and ecological farming systems, and to evaluate the impact of farming system, manure or fertiliser application and year on the presence of weeds in maize stands from 2014 to 2016. In the integrated non-fertilised maize cropping system, the following weed species were dominant in the spring: Amaranthus retroflexus, Cirsium arvense, Chenopodium album, Persicaria maculosa and Echinochloa crus galli. In the integrated fertilised maize cropping system, the following weed species were dominant in the spring: Amaranthus retroflexus, Chenopodium album, Cirsium arvense, Echinochloa crus galli, Convolvulus arvensis and Cardaria draba. In the integrated maize cropping system, Silybum marianum occurred as a weed at medium density. Silybum marianum was cultivated two years ago and its seeds were in a state of dormancy for that time. The efficacy of the herbicide treatment in the integrated system was excellent. In the ecological non-fertilised maize cropping system, the following weed species were dominant in the spring: Amaranthus retroflexus, Chenopodium album, Cirsium arvense, Avena fatua and Sonchus oleraceus. In the ecological fertilised maize cropping system, the following weed species were dominant in the spring: Amaranthus retroflexus, Chenopodium album, Echinochloa crus galli, Avena fatua, Persicaria maculosa, Cirsium arvense and Convolvulus arvensis. In the ecological farming system, due to insufficient mechanical weed control, a higher level of maize infestation with Avena fatua as an annual grass weed species was detected.

In recent years, sweet and sour cherry production in Serbia has increased. Under Serbian agroecological conditions, pathogens causing leaf diseases threaten the success of sweet and sour cherry production. In the period 2012–2019, the health status of cherries was monitored in more than 30 locations. Depending on the production system, the following leaf pathogens were identified: Blumeriella jaapii, Wilsonomyces carpophilus, Mycosphaerella cerasella, Phoma prunicola, Podosphaera clandestina and Pseudomonas syringae pv. syringae and morsprunorum race 1. Leaf pathogens caused premature defoliation, which adversely affected bud formation for the next growing season and increased susceptibility to freezing. Therefore, attention should be focused on correct leaf pathogen identification, and proper selection, application and rotation of fungicides.

Raspberry production has a long tradition in the Republic of Serbia, and the raspberry is the most economically important berry crop. According to data for the period from 2006 to 2016, the Republic of Serbia was ranked fourth in the world in the production of this fruit crop. The paper presents an analysis of raspberry production in the Republic of Serbia using statistical data from the previous years, which were compared with 2016 data. For comparison and analysis, we used the data presented on the FAOSTAT statistical database website and the Statistical Office of the Republic of Serbia (RZS) website. The analysis of the available data for the period 2006-2016 shows that the total yield of raspberries in this period varied, as did yield in tonnes per hectare, which ranged from 5.3 to 6 tonnes, depending on year. A sudden decrease in total yield in 2012 and in all subsequent years until 2016 was also observed. This was caused by a sudden reduction in the area under raspberries.

The first local cultivar of winter pea for grain, 'NS MRAZ', was developed by pedigree selection from the hybrid population created by crossing local populations and one French line of pea. The cultivar has a high seed yield potential, exceptional earliness and tolerance to low temperatures. Its average plant height is 75-85 cm; it is of the afila type of pea, tolerant to lodging and of uniform maturity. Its genetic potential for seed yield is more than 7,000 kg ha-1, and it achieved an average seed yield of 5,110 kg ha-1 in three-year trials, while seed yield in production conditions was above 5,500 kg ha-1. Thousand-grain weight is about 200 g, which was the goal achieved in reducing the amount of seed per unit area. Protein yield ranged from 1,100 to 1,200 kg ha-1.

Variability in the percentage of seed germination was studied in four winter barley cultivars ('Jagodinac', 'Premium', 'NS 489' and 'NS 495'), grown under four nitrogen application rates (control N0=0, N1=20, N2=40 and N3=60 kg ha-1) during two years of the experiment. The experiment was carried out as a randomised block design in 5m2 plots and with four replications. In both experimental years, the average seed germination was over 90.0% for all barley cultivars and in each nitrogen fertilisation treatment. The maximum seed germination percentage was 98.0% in 'Premium' in the second year in the treatment N3=60 kg ha-1, and minimum germination percentage (90.1%) was also recorded in 'Premium' 'in the first year of the experiment in the unfertilised control (N0=0 kg ha-1). The obtained values of seed germination significantly differed among cultivars in the first and second year. Also, the average values of seed germination under four N fertilisation treatments were significantly different in both years. The average values for both years of the experiment were significantly different among cultivars and treatments. The values of seed germination for all cultivars increased with increasing nitrogen rates, suggesting that phenotypic variability in seed germination was affected by nitrogen fertilisation, which indicated a high value (81.87%) of the component of phenotypic variance for seed germination.
在为期两年的试验中，研究了4个冬大麦品种(‘Jagodinac’、‘Premium’、‘NS 489’和‘NS 495’)在4种施氮量(对照N0=0、N1=20、N2=40和N3=60 kg hm -1)下种子发芽率的变异。试验采用随机区组设计，在5平方米的地块上进行，有4个重复。在两个试验年份，所有大麦品种和每个氮肥处理的平均种子发芽率都在90.0%以上。在N3=60 kg ha-1处理下，“优品”第二年种子发芽率最高，为98.0%;在未施肥对照(N0=0 kg ha-1)试验第一年，“优品”的种子发芽率最低，为90.1%。不同品种的种子发芽率在第一年和第二年有显著差异。此外，4个氮肥处理的种子萌发平均值在两年内也有显著差异。不同栽培品种和处理间的年平均值差异显著。各品种的种子发芽率随施氮量的增加而增加，表明施氮影响了种子萌发的表型变异，表明种子萌发的表型变异分量较高(81.87%)。

A field trial was conducted in 2016-2017 to determine the effect of different rates of mineral fertilisers, especially phosphorus, and lime on grain yield, yield components and their correlation in the spring barley cultivars 'Dunavac' and 'Novosadski 456' under dryland farming conditions at the experimental field of the Secondary School of Agriculture, Kraljevo. The experiment was performed on a very acidic soil (pHH2O 4.5), in a randomised block design with three replications. Grain yield, stem length, number of spikes m-2, spike length, number of grains per spike and grain weight per spike increased in response to mineral fertilisers and lime. Both cultivars performed better under mineral fertilisation and liming treatment than under increased phosphorus fertilisation, as the availability of macro- and micronutrients increased with increasing soil pH i.e. due to phosphorus immobilisation in the highly acidic environment. In general, significant positive correlations were observed among yield components, and between grain yield and its components. Grain yield was significantly positively correlated with number of spikes m-2, spike length, number of grains per spike and stem length. Correlations between grain yield and its components under diverse agroenvironmental conditions can guide the selection of cultural practices as well as the choice of cultivars for unfavourable growing conditions.

During two consecutive years (2018 and 2019) we investigated the effect of two clonal rootstocks on fruit weight, contents of some non-nutrients and total antioxidant capacity (TAC) in the flesh and peel of cv. ‘Hapke’ apple. Results showed that fruit weight was significantly higher on M.9 T337 than on M.26 rootstock and similar in both 2018 and 2019. M.26 rootstock significantly improved titratable acidity (TA), vitamin C content, total phenolic content (TPC), total flavonoid content (TFC) and TAC in comparison with M.9 T337. As regards fruit tissue, the peel was a significantly better source of acids, vitamin C and phenolic compounds, and had higher antioxidant capacity than the flesh. However, the rootstock fruit tissue interaction for the content of phenolic compounds indicated the complex nature of accumulation and distribution of acidity, vitamin C and phenolic compounds in apples.

Drosophila suzukii (Matsumura, 1931) is an invasive oligophagous pest native to southeastern Asia. The first documented report of this pest in Serbia was in 2014. The insect is a pest of healthy and physiologically mature (ripening) soft fruits. The aim of the study was to determine the efficiency of different types of baited traps in mass trapping specimens of this species in raspberry plantings. Five types of blends (attractants) were used for mass trapping. The experiment was set up on May 27th, 2017. Inspection and sample collections were carried out at 7-10 day intervals from June 4th to July 31st, 2017. Based on the analysed field data, we confirmed that standard trap S was the most efficient, with 8099 specimens caught in the experimental period. The number of caught specimens decreased in the deployed traps, as follows: trap T4 (695), trap T3 (682), trap T2 (643), and trap T1 (482) as the least efficient. Statistical analyses showed very significant differences between the standard trap and trap T1, and significant differences between the standard trap and the other trap types in the average number of caught specimens. No significant differences in trapping were found between the other trap types.

In this research, three groups of 12 lambs (6 male and 6 female) of the Pirot improved race were examined. The first group of lambs was fattened for 60 days, the second 120 and the third 180 days. Nutrition of the lamb to rejection (40 days) is the mother's milk. After 40 days, it switched to pelleted concentrate (with 18% protein) and a quality hay, which was ad libidum as the concentrate. At the end of the fattening, the lamb is slaughtered by the usual technique. The objectives of this study were to determine the influence of the length of fattening and gender of the lambs on the thickness of the subcutaneous fatty tissue. Differences in fat in the subcutaneous tissue dorsally, medially and laterally at the intersection between the 12 and 13 vertebrae are significantly different (P<0.01) both in male and female lambs in all three groups. At the intersection of the lateral side between the 12 and 13 vertebrae there are significant differences (P<0.01) between the first and second and between the first and third groups in both genders. The subcutaneous fatty tissue in females compared to male lambs is thicker in all measured locations. However, significant differences were found in the thickness of breast tissue (P<0.05) and dorsal between the 12 and 13 vertebrae (P<0.01) for lambs of the second group. Female lambs of the third group also have thicker subcutaneous fatty tissue, dorsally and medially between the 12 and 13 vertebrae (P<0.05).
