  In the past 10–15 years, the consumption of illegal drugs has increased significantly both in Hungary and in our county. In parallel with the society’s getting more and more open, the fulfilment of personal freedom, and the spreading of globalisation and individual culture, the use of drugs has become more and more accessible and acceptable to the young.

  Social problems are supposedly connected with the interviewees’ alcohol consumption. The EuroADAD questionnaire was used. The sample covered 190 interviewees. I have processed the data with the SPSS statistical program package.

  The linear regression analysis was applied to examine the interrelations between the elements under study. Almost consume alcohol as well. Among the examined socio-demographic variables, youth alcohol consumption was most affected by the gender of the respondent, the dissatisfaction with living conditions, and the change of residence.

  Sour cherry (Prunus cerasus) is a non-climacteric fruit. Storage optimization would enable the expansion of fresh consumption. The quality parameters are required for storage optimization. Those parameters are sugar content, acid composition, mineral content and alcohol content,
  moreover it is also planned to determine antioxidants, vitamins and patulin mikotoxin under different conditions. In this paper, we demonstrate the measurement options of these parameters.

  Mineral supplementation is very important in high producing farm animals. The estimation of exact mineral intake is very difficult in forage eating animals, like sheep. Accessing of long term mineral status seems to be possible using wool mineral analysis. However several factors can affect the results. Therefore, the aim of this study was to test the effect of breed and sampling location on the mineral content of sheep wool. 20 Dorper and 20 Tsigai sheep were chosen from the same farm. Samples were obtained from 3 locations (withers, side and quarter) and tested for 8 elements: Ca, Mg, Na, Co, Cu, P, S, Se , Zn. The samples were cleaned with ethyl alcohol from organic contamination, then after adding nitric acid were mineral analized using ultrasonic cleaning unit. The samples were analysed with ICP-OES (Perkin-Elmer, Optima 3300 DV). Statistical analyses were carried out by GLM procedure of SAS statistical analyses software. Differences between means were checked with Tukey-test. Significant breed differences were detected in the case of Mg, Na, S, Se in spite of the same feeding regime. The wool mineral content were within the reference range. The sampling location had no effect on the mineral content of wool.

  The monitoring of the most dangerous noctuid pests (Lepidoptera: Noctuidae) can be performed by species specific pheromone traps. Recently the development of traps catching female moths became the main objective of the studies. We studied the synergistic effect of vine and beer as natural additive on the effectiveness of baits containing isoamyl alcohol and acetic acid in Forró and Debrecen-Ondód. The addition of vine and beer had positive effect on catches and it was significant in case of two dangerous pest species Agrotis segetum and Lacanobia oleracea. The synergistic effect was also significant with regard to the number of detected species especially in case of lower abundances and rare species.

  The reduction in fossil energy and row material sources induces growing demand for renewable resources. The growing demand for herbal raw materials has land use impacts as well. One way to reduce the conflict between the food and energy crops can be the utilization of less favored areas by growing energy crops. Among the potentially available areas for this purpose the salt affected soils (SAS) occupy a significant territories. SAS with structural B-horizon (meadow solonetz soils) represent the most wide spread group of SAS in Hungary. About half of these soils have been reclaimed and used as arable land and the remaining 50% are used as grassland. Sweet sorghum production for manufacturing of alcohol production was investigated in a long term amelioration and fertilization experiment on a salt affected soil (meadow solonetz). By means of regression analyzes the effect of sodium content of the soil and increasing mineral fertilizer doses were studied. According to the multiple regression analysis only the effect of nitrogen fertilizer was significant. On the solonetz type salt affected soil the effect of water soluble salt content of the soil was not significant, but there was a closer correlation between the ammonium-lactate sodium content and the yield of sweet sorghum. The maximum green mass was 45–50 t ha-1, in the case of low Na content and high level of nitrogen fertilization.

  In order to quantify the potential yield of natural grass vegetation the relationship between the soil forming processes and the grass vegetation
  was investigated. Beyond the different forms of Na-accumulation, the spatial pattern (mosaic-like characteristic) is also an inseparable feature of salt affected soils. The difference in the water regime, caused by the micro-relief is the main cause of variability. The run-on water keeps the deeper parts of the catena position wet longer. The wet situation causes more intensive leaching. In the low-laying parts of salt affected soils species preferring wet situations (mainly Alopecurus pratensis) are in majority. On the higher parts of the micro-relief species tolerating dry situations (mainly Festuca  pseudovina) are dominant. The yearly grass production of low laying areas can be 4–7 t ha-1 but because of prolonged wet  conditions the grass is not grazed and mowing can only be in old state. This old grass is not proper for feeding, but it may be suitable as energy plant.

  The study investigates the drug addiction, school problems and the underlying emotional disorders of provincial young people. I assumed that school problems are connected with the
  youth’s legal and illegal drug consumption.
  In my research, I used the Euroadad questionnaire taken at the Drug Ambulance of Nyíregyháza. The sample covered 144 interviewees, 76.9% of whom were „diverted” from jurisdiction. The other respondents volunteered for the therapy.
  The linear regression analysis was applied to examine the interrelations between the elements under study.
  All of the 144 respondents have tried or regularly apply some consciousness-modifying substance. Most of them are young adults. The preferred drugs were marijuana and ecstasy. All
  consume alcohol as well. A significant connection can be proved between the majority of the psychological and school behavioural problems under survey and the drug abuse. The more problematic group covers those taking extasy.
