The aim of this research was to estimate breeding value and rank of Holstein – Friesian bulls for milk production traits. The analysis included 433 daughters of 10 bulls, calving for the first time in the period from 2007 to 2014, on 6 dairy farms of the Agricultural Corporation Belgrade AD. Fixed factors included in the model were the effects of the farm, genetic groups and calving season, and as a random factor the impact of the bull sire. The observed milk traits on the basis of which the breeding values were calculated were the milk yield (kg), the 4% fat-corrected milk yield (kg), the fat content (%), the fat yield (kg), the protein content (%) and the protein yield (kg). Sires were ranked according to abovementioned milk traits and Spearman’s Rank correlation was used to determine association between the ranks of the sires. According to the breeding values calculated by using the Best Linear Unbiased Prediction (BLUP) method, the sire 1676 was best ranked for the traits: milk yield (+363,88 kg), fat yield (+13,57 kg) and protein yield (+15,55 kg), relative to the average of daughters. The effect of the calving season showed a high significance (p<0.01) for the following traits: milk yield, 4% fat-corrected milk yield, fat yield and protein yield while there was no significant effect for other traits (p>0.05). Statistically very significant correlations between sire estimated breeding values for fat content and the protein content of 0,84 (p <0,01) and between the fat yield and the protein yield of 0,96 (p<0,01) was determined by the Spearman coefficient of correlation.

06. 2018. Abstract Western corn rootworm (WCR) ( Diabrotica virgifera virgifera LeConte) is one of the most important and potentially most dangerous pests of maize. Since its occurrence in Serbia in 1992, it has been present in almost all areas under maize cultivation. Alongside with all preventive measures, first of all, the crop rotation, which is considered the most economic one, a great attention has been paid to the forecast of the pest occurrence based on the flight dynamics and the population level. The flight dynamics, sex dominance, variations in the population level depending on the trap types and climate factors were observed on two locations: Crepaja in three-year continuous cropping (2005-2007) and in the experimental field of the Maize Research Institute, Zemun Polje in the duration of five years (2005-2009). According to the flight dynamics of WCR adults, the highest population level of this pest was observed in 2005, while the comparison of the number of adults over locations showed greater abundance of the pest in Crepaja than in Zemun Polje, which was attributed to extreme favourability of agro-ecological conditions on this location for the WCR development. The 2008-2009 period was characterised by the reduced number of WCR, which coincided with the extremely arid conditions that do not favour the development of this pest.

Information about dry matter accumulation is of great importance for further increase of barley yield. Various nonlinear and linear curves have been used to describe vegetative and reproductive growth for a number of agricultural crops. Although dry matter accumulation is an important parameter of crop growth, knowledge about biomass production under agro-ecological conditions of the Pannonian Plain are scarce. This study was undertaken to analyze the pattern of dry matter accumulation in two-rowed winter barley cultivars and changes in biological parameters of the logistic curve under different sowing dates and growing seasons. Therefore, trials with two late cultivars of two-rowed winter barley were conducted in two growing seasons and four sowing dates. Results from this study indicate that dry matter accumulation in both growing seasons followed a typical sigmoid shape. Delayed sowing led to a significant decrease in the maximum value of plant dry weight, the termal time needed to reach maximum value and duration of exponential growth, and increase in maximum crop growth rate. These results indicate that apart from appropriate cultivar selection, early barley sowing is also important to achieve high plant dry matters one of the main determinants of grain yield.

The presence of hard seeds as a result of water impermeable seed coat is common in species of Fabaceae family. For wild plants, this characteristic allows better survival, but for agriculture production, hard seeds are undesirable, due to delayed and uneven germination. In seed testing laboratory several pre-treatments (pre-chill, mechanical scarification) can be applied for germination testing of these species. In this paper, Proficiency test 17-2 germination results of Trifolium repens seeds conducted in 150 laboratories around the world are presented. Those tests are organized by the International Seed Testing Association (ISTA) and are mandatory for all accredited laboratories. In this way laboratory’s competence (staff, apparatus, test methods) is checked. In August 2017, samples of three Trifolium repens seed lots were distributed. In the Seed Testing Laboratory at the Maize Research Institute Zemun Polje (LIZP), germination was tested in September using mechanical scarification and pre-chilling (2 days at 5-10°C) prior to germination at 20°C. Among 90 accredited participants, only one more laboratory applied mechanical scarification, 42 laboratories did not use any pre-treatment, and 39 laboratories applied pre-chilling. Obtained germination results in LIZP (Lot1-84.50%, Lot2-84%, Lot3-88.50%) were higher than overall mean (Lot1-76.95%, Lot2-79.63%, and Lot3-83.27%). The main conclusion of this Proficiency test is that seed scarification significantly reduced the number of hard seeds in favour of normal seedlings. The reason for the rare application of scarification may be the requirement of the applicant to obtain adequate information regarding the number of hard seeds that will appear during seed sowing.
