Opisane so agrarnopolitične razmere, ki so v Evropski zvezi (EZ) in v Sloveniji pripeljale do uvajanja kmetijskega knjigovodstva po FADN metodologiji, s poudarkom na dohodkovnih vidikih kmetijske ...politike, ki zahtevajo informacije o dohodkih kmečkih družin. Metodologija v Sloveniji je podobna sistemu FADN, ki je v uporabi v EZ. Rezultati za Slovenijo za leta 1994 do 1996 ne morejo skriti začetnih problemov postavljanja novega informacijskega sistema. Rezultati niso povsem skladni, vprašljiva je njihova reprezentativnost in primerljivost s kazalniki v EZ. Nujna je izpeljava strukturnega popisa slovenskih kmetij in dokončanje postavitve celotnega sistema, z vzporednimi izračuni za neposredno poslovno odločanje. Omenjeni so tudi nekateri problemi načelne narave vpeljanega FADN, zaradi katerih ta ne ustreza dejanskim potrebam kmetijske politike.

This paper presents electronic tool to support farmers in fertilization planning. It is developed as a spreadsheet model, utilizing optimization potential of mathematical programming techniques. ...Described problem of fertilization planning is rather simple from technological-expert viewpoint, but methodological application of multi-criteria paradigm makes it more complicated. In the paper focus is put on economic efficiency of fertilization. Hypothetical case illustrates its application as well as strengths and weaknesses of methodology applied.

The paper presents multiple criteria approach to deal with risk in farmer’s decisions. Decisionmaking process is organised in a framework of spreadsheet tool. It is supported bydeterministic and ...stochastic mathematical programming techniques applying optimisationconcept. Decision making process is conceptually divided into seven autonomous modulesthat are mutually linked up. Beside the common maximisation of expected income throughlinear programming it enables also reconstruction of current production practice. Income riskmodelling is based on portfolio theory resting on expected value, variance (E,V) paradigm.Modules dealing with risk are therefore supported with quadratic and constrained quadraticprogramming. Non-parametric approach is utilised to estimate decision maker’s risk attitude.It is measured with coefficient of risk aversion, needed to maximise certainty equivalent foranalysed farms. Multiple criteria paradigm is based on goal programming approach. Incontribution focus is put on benefits and possible drawbacks of supporting weighted goalprogramming with penalty functions. Application of the tool is illustrated with three dairyfarm cases. Obtained results confirm advantage of utilizing penalty function system. Besidegreater positiveness it proves as useful approach for fine tuning of the model enablingimitation of farmer’s behaviour, which is due to his/her conservative nature not perfect orrational. Results confirm hypothesis that single criteria decision making, based onmaximisation of expected income, might be biased and does not necessary lead to the best -achievable option for analysed farm.

This rapid communication presents main results of the analysis of the income impacts of different direct payment policy options after the accession of Slovenia to the EU at the level of agricultural ...households. By applying static deterministic total income model, different post-accession direct payments policy options were investigated, with special attention given to the 2003 Common agricultural policy (CAP) reform provisions. The main conclusions based on model results are: i) the improved post-accession income situation of analyzed households under all post-accession policy scenarios, ii) standard direct payments scheme estimated as income most benefi cial, followed by basic fl at-rate area payment option (entirely decoupled) and iii) detection of possible redistributive impacts of 2003 CAP reform in favour of agricultural households engaged in extensive agricultural production.
Formulation of fertilization plan is important task in agricultural production, but
frequently performed by advisors without necessary information about individual
plots and fertilisation practices ...applied by individual farmers. With increasing
concerns for environment and sustainable production it is therefore important that
fertilization planning is done by farmers. High fertilizers' prices also urge to their
rational application, achievable only on the basis of plans for several years. In the
article an electronic tool for fertilization plan formulation is presented. It is developed
as a multi-criteria decision making model based on mathematical programming
techniques. Hypothetical case illustrates its application as well as strengths and
weaknesses of methodology applied.
