  In this paper the author summarized the definitions and operationalisations of the safety culture and safety climate concepts. He analyzed the Hungarian and international safety
  management scientific literatures. He also analyzed the scientific definitions and summarised the common and different elements. The author emphasizes that the many different scientific safety culture researches had been created good possibilities to find the common surfaces. Based on the international safety culture operationalisation practices the author identified a composition of safety culture dimensions which could be a possible basis for the Hungarian safety culture researches. These dimensions are:
  ???? values (individual and organizational) from this result scale of values,
  ???? attitudes (individual and organizational),
  ???? motivations,
  ???? perceptions,
  ???? social status and estimation of the occupational safety and health,
  ???? position and estimation of the occupational safety and health communication,
  ???? position and estimation of the occupational safety and health tranings,
  ???? measuring of confidence, optimism, fatalism and anomic characteristics,
  ???? good practices and behavior,
  ???? influence and estimation of the work,
  ???? risk perception and safety level perception,
  ???? contentment.with occupational safety and health.

  The aim of this work was to analyse the effect of K, P and N supplies on the yield of winter barley in a long-term mineral fertilisation experiment with clearly distinct soil nutrient supply levels in order to develop fertilisation guidelines for winter barley growers. The experiment was set up in 1989 on a chernozem meadow soil calcareous in the deeper layers, applying all possible combinations of 4 levels each of N, P and K fertiliser, giving a total of 64 treatments.

  The results of analyses performed in 2011 and 2012 can be summarised as follows:

  1. In 2011, when rainfall supplies were deficient in the shooting phase, improved K supplies (324 mg kg^-1 AL-K₂O) increased the grain yield, but in 2012, when rainfall supplies were more evenly distributed, K supply levels in the range 210–335 mg kg^-1 AL-K₂O had no significant influence on the yield of winter barley.
  2. An analysis of the P treatments revealed that, compared to the 119–133 mg kg^-1 AL-P₂O₅ level (P₀), better P supplies (186–251 mg kg^-1) led to a significant increase in the grain yield.
  3. In both years rising N rates significantly increased the yield up to an annual N rate of 160 kg ha^-1.

        4. A K×N interaction could only be detected in the nutrient supplies of winter barley in 2011. The yield-increasing effect of N fertiliser was more    pronounced at better K supply levels, while K fertiliser led to higher yields in the case of better N supplies.

  The author examined the human social influence factors of the occupational safety and health and number of workers at thirteen different agricultural firms. He’d measured at these enterprises the demographic characteristics and the risk sensibility of farmlabourers at scopes of activities and some related occupational safety and health attitudes from the psychosocial factors. He used questionnaire and personal guided interviews and methodical examinations. He used seven graded Likert-scale (-3...0...+3) (Malhotra, 2005) for qualification of answers. He established that selection by the leaders don’t prefer the special skills. He stated that the examined farm-labourers have got a low risk sensibility, but the statistics of the accidents not certifies it. With the occupational safety and health related attitudes influence the relation to the occupational safety and health, and to comply with OSH rules. It was established that the rate of quasi-accidents is relative high at agricultural workers.
