River landscapes are perceived and preferred as a particular phenomenon of nature. Planning and management of river areas anticipate conflicts of various interest groups that are most commonly identified in researches as experts and non- experts (the public). The article presents the results of the comparison of student attitudes and those of experts for regional, cross-border area of Slovenia, Hungary and the Croatian landscape transformations on the Drava and the Mura rivers. The questionnaire, which consisted of visual and written parts, explored attitudes on the dimensions of the landscape, linkage with river scenery, views on the transformation of river landscapes and trust in the authorities responsible for planning and management of the river area. The results suggest a common positive platform of trust in a paradigm of sustainable management, and international border rivers management, but also indicate different sensitivity of the observed groups considering the transformation of river landscapes and trust in the authorities.

Glutenins loci were used for variability estimation in 50 varieties of hexaploid winter wheat originated from Croatian breeding centres. Polyacrylamide gel electrophoresis (PAGE) in presence of sodium dodecyl sulphate (SDS) was used for determination of high molecular weight glutenins (HMW-GS). Number of allels per loci ranged from 3 at Glu-A1 to 5 at Glu-B1 and Glu-D1, the average number of allels was 4.33. The highest genetic diversity was found at loci Glu-B1 (He=0.687). The most frequent subunit at loci Glu-A1 was 2* (56%). At loci Glu-B1 the most common combination of subunits was 7+8 with 40%, and at loci Glu-D1 5+10 with 68%. The study also defines high quality varieties with largest number of Glu-scores. The results attained from this study allow further development of specific breeding programs for winter wheat quality improvement and improvers creation.

Sequencing and detailed study of the genom of domestic animals began in the middle of the last century. It was primarily referred to development of the first generation sequencing methods, i.e. Sanger sequencing method. Next generation sequencing methods are currently the most common methods in the analysis of domestic animals genom. The application of these methods gave us up to 100 time more data in comparison with Sanger method. Analyses including RNA sequencing, genotyping of whole genome, immunoprecipitation associated with DNA microarrays, detection ofmutations and inherited diseases, sequencing ofthemitochondrial genome and many others have been conducted with development and application of new sequencing methods since 2005 until today. Application of new sequencing methods in the analysis ofdomestic animal genome provides better understanding of the genetic basis for important production traits which could help in improving the livestock production. © 2015, Faculty of Agriculture in Osijek.

Aim: To determine the frequency of baby walker use and the knowledge of parents of preschool children from the city of Osijek about baby walkers and to evaluate the interconnection between these variables as well as the interconnection between these variables and the level of parental education. Methods: This cross-sectional study was conducted using an anonymous questionnaire in May 2011 among parents of preschool children attending kindergartens in the city of Osijek. The questionnaire used in this study contained questions relating to age, gender and education level of parents, usage of baby walkers and knowledge of parents about this usage. The response rate was 38.4% (653/1700). Results: Among all the parents there were 63.1% (412/653) of those who used baby walkers. Parents with college or university education used baby walkers much less compared to parents with lower levels of education, and this difference was statistically significant (x2 = 45.093, df = 2, p

The first part of the paper gives an overview of research papers on the landscape with special emphasis on the visual and environmental studies. Long-time development of visual research landscape provides a basis for a critical review pointing to the need to increase the validity of visual research, the category selection, visual perspective of a landscape, as well as the technical characteristics of the performance of visual material. In this paper the results of research of attitudes of Hungarian and Croatian students, conducted through visual materials and questionnaires on river landscape transformation are interpreted. The results indicate the need for harmonization of cross-border categorizations of the observed landscape, as well as the complement of the objective parameters by the parameters which include cultural accumulation.

Private Finance Initiative (PFI) is a model of Public Private Partnership (PPP) used to deliver public services which are not commercial in nature. Naturally, lients want to achieve successful PFI projects and they need to have a tool for evaluating the achieved success. Generally there are still no accepted frameworks for assessing project success but several recommendations for development of an evaluation template for assessing the success of PFI schemes exist. To enable success assessment there is a need to identify adequate success criteria. In this paper, important PFI project success criterion for lient called "Starting Date of Operation" will be identified. Model for its application on evaluating PFI project success will be recommended and its empirical applicability on suitable PFI projects in Croatia will be demonstrated. Descriptive statistics indicator will be calculated and referent base for success evaluation of PFI projects in Croatia applying "Starting Date of Operation" success criterion will be established.

Biological control is the use of live beneficial organisms and products of their metabolism in the pests control. Plant pathogens can be used for weed control in three different ways: as classical, conservation and augmentative (inoculative and inundated) biological control. Inundated biological control involves the use of bioherbicides (mycoherbicides) or artificial breeding of pathogens and application in specific stages of crops and weeds. Biological control of weeds can be used where chemical herbicides are not allowed, if resistant weed species are present or in the integrated pest management against weeds with reduced herbicides doses and other non-chemical measures, but it has certain limitations and disadvantages.


Field experiments with natural population of European corn borer (ECB) were conducted in three vegetation seasons (2012-2014) at Agricultural Institute in Osijek. The experiment was set up in a randomized block design as split-split plot method, with three repetitions. This plot has been constantly maize - soybean rotation for already 15 years. It was a 3x3x4 factorial experiment with three irrigation levels (A1- non-irrigated (only natural precipitation), A2-from 60% to 80% field water capacity - FWC and A3-from 80% to100% FWC), three nitrogen fertilizer levels (B1-0, B2-100 and B3-200 kg N/ha) and four different genotypes (C1-0SSK 596; C2-0SSK 617; C3-0SSK 602 and C4-0SSK 552).The aim of this study was to determine the effect of different levels of irrigation, nitrogen fertilization and genotypes on occurrence and damage of maize plants by the European corn borer larvae and relation between leaf feeding larvae with nitrogen and silicon concentration as well as C/N ratio. At the end of each growing season, ten maize plants from each variant were cut. Ear weight for each specific plant (g), tunnel length (cm), number of larvae in stalk, number of larvae in the ear shank, ear shank damage (cm) and total number of larvae in maize plantwere determined. In silking stage (middle of July) ten leaves (below the ear), from 10 maize plants were sampled on each variant. Nitrogen, carbon and silicon concentrations were determined in maize leaf (%) and C/N ratio calculated. In 2014, a significantly lower ECB attack was determined taking into account lower temperatures and higher amount of precipitate compared to the previous years. Dominance of Z-type European corn borer on pheromone traps in the area of eastern Slavonia was confirmed. Increasing the level of soil water content, damage from larvae was reduced and increasing the level of nitrogen fertilization feeding activity was increased. We have confirmed different hybrid resistance in regards to damage from larvae, so C4 (OSSK 552) genotype was the most resistant while C1 (OSSK 596) was the most susceptible. Concentration of nitrogen and silicon in a maize leaf was in negative correlation as well as nitrogen concentration and C/N ratio. Hybrid resistance didn't entirely depend on nitrogen and silicon concentrations, even though there was greater damage on most hybrids with higher concentration of nitrogen, while damage was reduced with higher concentration of silicon. © 2015, Faculty of Agriculture in Osijek.

In a five year experiment the effect of liming on maize and spring barley grain yields and maize nutrient status were examined. The field trial with application of increasingrates of dolomite (0, 5, 10 and 15 t ha-1) containing 56% CaO and 40% MgO was conducted on the very acid soil with pH (KCl) 3.78 on the location in the central Croatia(45°30' N, 17°11' E). Maize crops were grown during 2003-2005 and 2007, whereas spring barley was grown in 2006. Soil chemical properties and maize leaf nutrient concentrations were evaluated after the second year of trial. Liming raised the soil pH by 2.62 pH units and AL-P2O5 by 5.65 mg 100 g-1 and increased crops yield inall years. There were no statistically confirmed differences between treatments with 10 and 15 t ha-1 dolomite for maize yields, while barley grain yield significantlyincreased only at the highest dolomite rate. Liming also improved maize nutritional status and increased P, Ca, Mgand Mo concentration and decreased high Mn content to the adequate range.
