The paper analyses the influence of four main weather parameters on alpha-acidcontents for the main hop variety Aurora (Super Styrian Aurora) in Slovenian production for the time period 1994-2009. Through inspection of correlation coefficients, it tries to find specific times of the year when theweather conditions affect the alpha-acid content with a view to prediction in Slovenia. The most significant time periods of weather that influenced the alpha-acid contents of the Aurora variety during the growing season are identified as attributes of temperatures calculated from the interval from 25th to 30th week (T2530, r = -0.88, P ( 0.01), as attributes of rainfall and sunshine from the interval from 25th to 29th week (R2529, r = 0.85, P ( 0.01 and S2529, r = -0.75, P ( 0.01) and attributes of relative humidity from the interval from 27th to 32nd week (RH2732, r = 0.71, P ( 0.01). The attribute T2530 represents the sum of active temperatures from June 18 to July 29 of that year. Similarly, the attribute R2529 corresponds to the rainfall (in mm or L/m2) that fell during the June 18 to July 22.

An analysis of the development and current situation in agriculture and agricultural policy in Western Balkans countries (WBs) in relation to the EU accession process. Most WBs has quite high but unsued potential for agriculture. The small-scale and fragmented nature of private farming remains a general characteristic of agriculture in all WBs. After a decline in the volume of agricultural production due to transition and armed conflicts an increase seems to have set in for WBs since 2000. However, yields still lag behind the EU average in all WBs. In general, agricultural producer prices are rather high, mostly above the EU average, indicating weak price competitiveness for most WB products. Serbia is the only net exporter of agricultural and food products. Budgetary transfers to agriculture have been at a low level, except in Croatia, but mostly are increasing repidly. The WBs lack a stable agricultural policy and a true strategy of reforms and adjustment to EU requirements.

Early information on yield has a special importance in the intensive apple production. Since the majority of older forecast methods are labor, time, organization and cost intensive a hybrid model based on image analysis and neural network was developed. From the end of fruit thinning in June till harvesting digital images of 120 trees of yellow-skin 'Golden Delicious' (fourtimes) and 120 trees of red-skin ćBraeburnć (five times) were captured from intensive orchards. Firstly, each image was processed by image analysis algorithm to receive the data on number of fruits and a yield forecast, for each sampling period separately, which served as the input information for modeling the yield with the artificial neural network (ANN). The forecast of the hybrid method showed a higher accuracy than the image analysis for both varieties, since the new procedure managed to increase the correlation betweenthe forecasted and weighed yield from 0.73 to 0.83 for 'Golden Delicious' and from 0.51 to 0.78 for 'Braeburn'. The standard deviation/image was decreased from 4.79 to 2.83 kg for 'Golden Delicious' and from 3.64 to 2.55 kg for 'Braeburn'. To introduce the new method in practice, additional tests on various locations including all important apple varieties are recommended.

The article highlights the relevance and usefulness of the Slovenian spatial databases for the case of land cover database at the agricultural ministry for the purpose of land use change analysis and spatial analysis in Slovenian agriculture. The advantages and some limitations of spatial databases, with the emphasis on the evidence of actual agricultural and forest land use, are displayed based on the analysis of actual land use and land use changes with the use of transition matrix method, within the Landscape park Ljubljansko barje.

The article analyses the influence of the 2004 enlargement and of the 1998-2002 accession negotiations on the Common Agricultural Policy (CAP) reform. In contrast to the dominant liberal institutional political economy models that explain pre-enlargement CAP reforms in terms of the negative trade related policy externalities, the common institutional setting, a critical realist explanatory model is proposed. In accordance with the model, the reforms were facilitated by the conflicting interests and the differences in capacity of the capital fixed to agricultural production in the member states and the candidate countries. The capacity of the agro-capital is defined by comparing the agricultural production structures, which were in the case of the old member states sustaining high levels of the fixed capital and which were in the case of the candidate countries, on average, underdeveloped and under-capitalized. The model is supportes by the empirical analysis of the CAP reform and the accession negotiations process.
