Agro-economic potentials of the East Slovak Lowland agricultural soils

J. Vilček, O. Hronec

Agric. Econ. - Czech, 2004, 50(2):83-87 | DOI: 10.17221/5171-AGRICECON

The high rate of the Stagnosols and Gleysols in the East Slovak Lowland substantially influences the potential utilisation of the existing agro-ecosystems. On the basis of the pedologic and informative system of Slovak soils investigation, we determined the possible structural, productive and economic parameters of the soil representatives in the East Slovak Lowland, its districts and soil-ecological regions with the help of geographic informative systems. 46.9% of the soils are not profitable for the plant growing without subsidies. At the average expense per one hectare of agricultural soil 10 227 SKK, it is possible to expect the yields of approximately 10 295 SKK/ha, which means profit without subsidies 68 SKK/ha (profitability rate 0.67%). The best natural and economic results in plant production can be expected in the Michalovce and Trebišov districts and the soil-ecological regions of Ondavská rovina (Ondava flatland), Laborecká rovina (Laborec flatland) and Kapušanské pláňavy (Kapušany welds).

F. Střeleček, R. Zdeněk, J. Lososová, M. Jílek

Agric. Econ. - Czech, 2004, 50(10):431-444 | DOI: 10.17221/5230-AGRICECON

The article deals with characteristics of local communities and rural regions. Local communities are defined both according to the standards of population density and the number of inhabitants. In the article, there are treated especially the indicators of population development (balance of migration), economic activities of the inhabitants, unemployment rates, structures of the population according to the sector of national economy and the indicators of education. These indicators have been calculated on the basis of data of the Census 2001, municipal and regional statistics and the Department of Employment data concerning the unemployment rate.

Production and utilization of doubled haploids in Brassica oleracea vegetables

M. Klíma, M. Vyvadilová, V. Kučera

Hort. Sci. (Prague), 2004, 31(4):119-123 | DOI: 10.17221/3804-HORTSCI

A possibility to increase the efficiency of plant regeneration from microspore-derived embryos of selected botanical varieties of Brassica oleracea was investigated from 2001 to 2004. More than 400 regenerants of R1 generation were derived in kohlrabi, cabbage and cauliflower by means of different modifications of microspore culture technique. Distinct genotype differences in embryogenic responsibility and regenerative ability of microspore embryos to whole plants were detected. The highest frequency of embryogenesis and subsequent regeneration of plants were achieved in cauliflower cultivar Siria F1, kohlrabi line P7 and some experimental F1 hybrids of cauliflower. The best production of embryos was obtained when donor plants were grown in the growth chamber under controlled light and temperature conditions. The regeneration of plantlets was considerably improved by repeated subculture of cotyledonary embryos on media with various combinations of phytohormones and excision of the cotyledons from mature embryos. The percentage of plant regeneration from subcultured embryos in kohlrabi ranged from 11.11 to 63.64%, in cauliflower from 23.53 to 46.19% and in cabbage from 5.88 to 52.00%. The utilization of regenerants for doubled haploid line production is often complicated by male sterility also in plants with the normal diploid chromosome number.

V.V. Podrázský, I. Ulbrichová

J. For. Sci., 2004, 50(6):249-255 | DOI: 10.17221/4622-JFS

Restoration of forest soil character after the change of agricultural land use has not been studied yet despite the large areas reforested since the late 40ies of the last century. This process takes place throughout Europe to an increasing extent at present. The reformation of forest soils was studied in the area of Český Rudolec town: Natural Forest Area 16 - Czech-Moravian Uplands, altitude 600-630 m a.s.l., bedrock is built of granites and gneisses, soil type is Cambisol, forest site type 5K1. The process of restoration of a new humus form was analysed in plantations of American red oak (Quercus rubra), Swedish birch (Betula pendula), European larch (Larix europea) and Norway spruce (Picea abies), the site was homogeneous. The particular tree species accumulated 12.81, 13.81, 46.57 and 44.76 t/ha of surface organic matter during the last 30-40 years, these values are typical of forest sites at lower and middle altitudes and corresponding tree species composition. The effect of broadleaved species and conifers was markedly different, in the first case pH in KCl ranged 3.8-3.9 (mineral soil) and 3.5-5.2 (holorganic horizons), being 3.5-3.8 (mineral soil) and 3.1-5.1 (holorganic layers) for the conifers. Visible effects of the particular tree species were also evident in the soil adsorption complex and in the contents of plant available and total nutrients. The results can be summarised and generalised: - the forest soil character is reformed at lower and middle altitudes in a relatively short time from the aspect of surface humus accumulation and basic soil chemistry (30-40 years), - birch exhibited the best revitalisation effect among the studied species, - American red oak and Norway spruce humus accumulation potentials were different although the soil chemistry was comparable, - Norway spruce did not show a remarkable degradation effect until now, - on the contrary, European larch appeared as a site degrading species.

Different types of damage in mountain forest stands of the Czech Republic

B. Lomský, V. Šrámek

J. For. Sci., 2004, 50(11):533-537 | DOI: 10.17221/4652-JFS

Forests in the Czech Republic are highly influenced by the antropogenous factors - those are particularly air pollution, pollutant deposition, soil degradation, change of the natural forest ecosystems, and also global climate changes. Significant damages due to air pollution are visible already 50 years (the Ore Mts. region). Since 1989 the sulphur emission has decreased significantly. By the end of 90ies SO2 emission was reduced in nearly 90%. In the 1990-1995 period, the change of air pollution situation in mountain regions resulted into the spruce stands condition improvement, and good progress of transitory stands (birch, blue spruce, mountain pine, alder etc.). Following development was not that ideal, however. Since 1995, various symptoms of damage have been observed, caused by the complex of factors. During the winter 1995/1996, within the whole region of the Czech Republic, reddening of the last needle year class of spruce was observed in the altitude over 700 m. These symptoms were the most visible in the eastern part of the Ore Mts., where 3-4 needle year classes were affected, or even tree decay observed. An acute damage was caused by direct impact of the high SO2 concentrations. The average defoliation was over 60% in stands assessed. About 12,578 ha of spruce stands were damaged, 1,300 ha of them has completely died. The rest have regenerated successfully in following period. After following winter, in spring 1997, the damage of transitory birch stands was observed in all the northern mountain regions. In the Ore Mts. ridge birch did not flush at all, the leaf lost was observed in a vast area with variable intensity in altitudes over 800 m above sea level during the springtime. In total 3,400 ha of birch stands was damaged, in 1998 it was nearly 5,428 ha. Birch completely died at about 2,550 ha, in following period the damage development stagnated. Similar damage of smaller extent has been observed also in other parts of the country, in higher elevations, situated above the inversion layer during the spring months. After winter 1999, vast damage of the spruce stands, manifested in yellowing of older needle year classes, and gradual needle drying and fall, affecting the stand of all age categories, was observed in the western part of the Ore Mts. but also in other regions. Yellowing was observed on 2,000 ha in 1999, next year it was 6,500 ha, and in 2001 about 9,000 ha was damaged within the Ore Mts. A new type of damage has been observed in the Orlické hory Mts. ridge caused again by the stressing factors complex after the winter 2001/2002. Nitrogen deposition seems to be one of major problem. The damage presented shows that in spite of significant lowering of air pollution load the forest stands health state in air polluted regions is not stabilized.

SAPARD: experiences and challenges for the future

H. Hudečková, M. Lošťák

Agric. Econ. - Czech, 2004, 50(4):152-160 | DOI: 10.17221/5183-AGRICECON

Using the research technique of document study, the paper analyses printed mass media with national coverage (from the national daily newspapers to specialised journals) during the period of the beginning 2002 - October 2003. The task of the paper is to outline the experiences with the SAPARD Programme as they are recorded in mass media and found among stakeholders (i.e. farmers and the representatives of rural municipalities or rural businesses). The text prolongs the previous investigation among Czech SAPARD shareholders and compares the findings. The SAPARD Programme showed that they are the rural stakeholders who are well prepared to act in the institutionalised frames of the EU structural policy. As a necessary condition of stakeholders for the success in getting the EU funds, there are the visions, enthusiasm and appropriate objects for the the intended project. The issues which have to be developed (and therefore they are the challenge for the future) are achieving better co-ordination of activities, quality and good system of information, dissemination of gathered experiences and simplification of administration.

Enlargement of the European Union - a new economic and social reality for agrobusiness entities

E. Horská

Agric. Econ. - Czech, 2004, 50(8):353-358 | DOI: 10.17221/5216-AGRICECON

Goal of the paper is to identify opportunities and threats following from the European integration process and influencing the agribusiness entities in the accession country - Slovak Republic. These topics have begun one of the current themes connected with the approaching date of the Slovak Republic accession to the European Union. It is related to the fact, that agrarian but mostly food processing markets have their own specificities, appearing with their typical high sensitivity to the outside environment influence and strong enterprise motivation to competition. In the paper, there are also outlined tasks for business management to analyze external environment, to identify the decisive strengths and weaknesses, to overcome difficulties to adopt European standards and to use opportunities in a wider market place.

K. Vančura, P. Pacourek, J. Řezáč

J. For. Sci., 2004, 50(11):505-509 | DOI: 10.17221/4647-JFS

This paper gives an overview of Czech forestry policy and legislation since the beginning of changes in the CEEC plus developments and activities of the main forestry institutions. These activities are referred to in the background material given for the political transition period and also related to the Pan-European and global forestry processes. The philosophy of forestry in the Czech Republic is based on the international framework set out by the first Ministerial Conference on the Protection of Forests in Europe and also in conjunction with the preparation of the Czech Republic for accession to the European Union. National and regional forest programmes are aimed at implementing the principles of sustainable forest management and a broad range of stakeholders from the forestry and environment sectors has been involved in its preparation. The current situation and main problems of forestry are given along with basic principles on how to solve such problems and also on how to fulfil obligations to future generations, and international commitments.

Technology and economy of energy crops

Z. Abrham, M. Kovářová, T. Kuncová

Res. Agr. Eng., 2004, 50(4):123-129 | DOI: 10.17221/4938-RAE

The cost modelling for growing and harvest of selected energy crops and further costs for recommended forms of energy crops processing to biofuels was conducted. Importance and effect of subsidies on resulted costs for biofuels production was assessed. The result are then total costs per unit of fuel weight which range from 469 to 1,806 CZK/t for biofuels processed to form of chopped material or pressed bales and from 881 to 2,466 CZK/t for briquettes and pellets. The result costs per energy unit in biofuel have ranged from 59 to 121 CZK/GJ. On basis of economical data is evaluated the biofuels competitive power in comparison with main competitive fuels on market. The energy crops specific costs without subsidies are higher thus their position on market will be complicated, lower specific costs can be expected only when residual biomass would be utilised (grain straw). The competitive power of the energy crops will be much better as the subsidies are utilised in 2004 and total specific costs for chopped material are from 82 to 142% of brown coal price, 95-137% for briquettes in comparison with the brown coal briquettes. The energy utilisation if winter wheat and sorghum is economically unsuitable.

Land market in Hungary

J. Popp, M. Stauder

Agric. Econ. - Czech, 2003, 49(4):173-178 | DOI: 10.17221/5375-AGRICECON

In Hungary, after the political and economical transition period of the nineties, the transformation of agriculture, the privatisation and the partial compensation brought about fundamental change in the land ownership structure. Recently, the private ownership of land has become dominant. As a result of the land compensation and the restoration of individual shares of the co-operatives members, unfavourable farm structures were established in a great number of cases; and consequently the redistribution of land property has become indispensable. The revival of the market is hold up, on one hand, by the present legislation of land acquisition (by Hungarian legal entities and foreigners) and, on the other hand, by the repugnance of the land acquisition of foreigners by a great number of people. The political risks, the EU accession and the changes to be expected concerning the EU subsidy schemes might also affect the land market in the long-term.

Barley response to the soil reserve of sulphur and ammonium sulphate in short-term experiments under controlled conditions of cultivation

J. Matula

Plant Soil Environ., 2004, 50(6):235-242 | DOI: 10.17221/4027-PSE

The objective of the paper was to determine an appropriate concentration of available sulphur in soil for the initial growth of plants. Based on previous researches two methods of soil extraction were used to acquire information on the soil reserve: water extraction (H2O 1:5, w/v) and extraction in 0.5M ammonium acetate with addition of NH4F (KVK-UF soil test). Spring barley was used as a test crop to determine the soil reserve of sulphur and its response to sulphur addition to the soil. A collection of 48 samples of topsoil from agriculturally important localities in the CR was made up for this purpose and the parameters of the nutrient status of the soil were remarkably different. A set of soils was used to establish short-time vegetation experiments in a plant growth chamber according to the scheme: A) control - without sulphur application and B) response variant with application of 30 mg S/kg of soil in the form of (NH)4SO4; nitrogen in variant A was adjusted by application of NH4Cl. Index of nutrient efficiency (IE = Y/N where Y = yield and N = nutrient concentration in the plant) and boundary lines of the point field were used to evaluate the efficiency of barley nutrition with sulphur. The efficient soil reserve of sulphur for the soil test H2O (1:5) when the ICP analytical technique was used was indicated in the range of 8-11 mg S/kg; 6-10 mg S/kg for sulphate detection on a SKALAR analyser. The efficient utilisation of sulphur by barley plants for the KVK-UF soil test was in the range of 7-12 mg S/kg. The conversion of the KVK-UF S-test to the index of soil reserve of sulphur by adding up a variable portion of the CEC value to the value of sulphur determined by the soil test (0.0167CEC + 9.1667) improved the closeness of the relationship between soil and plant.

Development of selected financial indicators for agricultural enterprises in the Slovak Republic

Z. Chrastinová

Agric. Econ. - Czech, 2004, 50(3):120-124 | DOI: 10.17221/5178-AGRICECON

Except of 2001 and 2002, the agriculture has produced losses of SKK 38.8 billion over the entire process of transformation. The losses in agriculture were caused by major disparities between the price of supplies to agriculture and prices of agricultural products, plus the restrictive subsidy and loan policy adopted in the early years of the economic reform. The economic situation has improved over the last two years. This was caused by the increase in subsidies, as well as by the continuing restructuring process (sales and liquidation of dubious assets, optimised production), reduction in numbers of loss-making enterprises, by growth and increase in efficiency of production and due to a substantial increase in earnings of many partnerships. However, even despite the positive trends current financial position of most agricultural enterprises does not meet the requirements for development in agriculture, with the rate of TFA (tangible fixed assets) depreciation achieving 50% (of that, depreciation of machinery stands at 70%). The earnings are moderate even in profit making enterprises, with 75% of those enterprises making only up to SKK 1.5 million in earnings.

Productivity of factors in the enlarged EU

G. Blaas

Agric. Econ. - Czech, 2004, 50(11):509-513 | DOI: 10.17221/5241-AGRICECON

The paper is examining the productivity of production factors in the EU-15 and some of the New Member States. International comparison shows that Slovakia is considerably lagging behind the EU-15 countries in the productivity of land and productivity of labour, but it is rather competitive in productivity of the fixed and variable capital. In order to get comparable data, the author adjusted figures on production of agricultural activities published in the Economic Accounts of Agriculture, and excluded the influence of different price - and support levels in the EU-15 and New Member Countries.

L. Jankovský, J. Beránek, A. Vágner

J. For. Sci., 2004, 50(3):118-134 | DOI: 10.17221/4607-JFS

Activity of fungi participating in the dead wood decomposition was studied in the Velký Polom Nature Reserve, Protected Landscape Area Železné hory. Two game-proof fences of an area of 0.30 ha (570 m alt.) and 0.19 ha (620 m alt.) were used as permanent sample plots. In both the plots, activities were monitored of wood-destroying fungi in 126.82 m3 dead wood, 104.05 m3 of which were in beech. After conversion to an area, the volume amounts to 258.82 m3 per ha. In the whole reserve, almost 220 species of macromycetes were recorded in the course of a mycological survey. Wood-destroying fungi are the dominant component of mycoflora representing more than 50% identified taxa of in the period under study. The proportion of mycorrhizal fungi amounted to 14%. A series of macromycetes considered to be saprophytes is bound to products of wood decomposition. Fomes fomentarius (L.) Fr., Fomitopsis pinicola (Sowerby) P. Karst., Ustulina deusta (Fr.) Petrak, Hypoxylon fragiforme (Pers.) Kickx, Ganoderma lipsiense (Batsch) Atk. and the genus Armillaria were the predominant species of wood-decaying fungi. As for rare macro-fungi, it is possible to mention Ascotremella faginea (Peck) Seaver, Stropharia albocrenulata (Peck) Kreisel and Tricholomopsis decora (Fr.) Singer.

Influence of amphibolite powder and Silvamix fertiliser on Norway spruce plantation in conditions of air polluted mountains

I. Kuneš, V. Balcar, M. Čížek

J. For. Sci., 2004, 50(8):366-373 | DOI: 10.17221/4663-JFS

The objective of the paper is to assess the effects of amphibolite powder (waste from a dust removing process in a rock pulveriser) and Silvamix slow release fertiliser on Norway spruce plantation in the harsh physical environment of the Jizerské hory Mts. The plantation characteristics such as mortality, annual height increment, stem base diameter, crown diameter and nutrient analyses are evaluated. A nine-year-long period of observation is summarised. The effects of both the forms of chemical amelioration seem to be positive and statistically significant. The benefits of the amelioration expressed in absolute figures have been easily observable until now. Recently, the importance of these benefits has decreased after the adaptation of planted trees to the mountain site and natural acceleration of their annual increment.

Quantitative evaluation of the effect of economic tools on economic policies in the food industry of the SR

D. Matošková, V. Ižáková

Agric. Econ. - Czech, 2003, 49(1):14-21 | DOI: 10.17221/5259-AGRICECON

The article deals with the evaluation of competitiveness in milling, feedstuffs, pasta, spirits, wine, beer and malt industries in the Slovak Republic. It further evaluates the impacts of economic policy tools on the stated sections of food industry by means of the PAM analysis. The impact of the policies on income, costs and profits of food production in the selected food industry branches has been discovered, based on the effects of divergences and coefficients of nominal and effective protection.

The analysis of proposals of the Common Agricultural Policy reform and its impacts for the EU

M. Vosejpková

Agric. Econ. - Czech, 2003, 49(6):278-283 | DOI: 10.17221/5387-AGRICECON

The Common Agricultural Policy (CAP) is of the character of a highly protective policy of the EU Member States. It includes a number of measures distorting the market directly and influences the farmers' incomes depending on their production. There have been two reforms of the CAP so far and the third one is prepared with intention to come into force from 2006; it is called Mid-Term Review (MTR). This reform is concentrated on keeping and increasing consumers' credibility and shifting to more competitive agriculture more orientated on market needs. The main Reform proposals include horizontal issues, i.e. Decoupling, Modulation/Degressivity, Cross-compliance, Farm Advisory System, IASC, Rural Development, and market issues concern dairy, cereals, rye, durum wheat, dried fodder, potato starch, seeds, nuts, rice, set-aside, carbon credit, beef. Besides the above mentioned goals, it is necessary to ensure conditions for rural development together with demands on environmental protection and improvement, so-called second pillar of the CAP. The attempt of cross-sectional summary and analysis of the MTR impacts for the EU was made in the article based on results of six studies performed by universities and DG AGRI in Brussels.

The shuttle migration with regard to social potential of rural settlements (case study)

H. Hudečková, L. Kříž

Agric. Econ. - Czech, 2004, 50(10):457-464 | DOI: 10.17221/5233-AGRICECON

This article concerns shuttle migration activities of rural inhabitants and at the same time asks how this phenomenon influences social potential of rural settlements. The authors draw on the social ecology. Among its basic topics belongs spatial behavior. The authors ask about the impacts of the extent of shuttle migration and of how rural inhabitants perceive it (the object of the survey are 5 municipalities in the Central Bohemia Region) on social potential of the municipality. This potential is indicated by a cooperation of the migrants and non-migrants in the local government, especially with regards to development strategies involving transport infrastructure and public-transport services. The used method is a sociological empirical research that combines quantitative and qualitative approach and uses the appropriate techniques, such as a document study, observation, questionnaires and time-and-space mapping. Analysis of the collected data leads firstly to identification of positives and negatives of the shuttle-migration activities for the rural settlements, and secondly results in outlining empirical research of the shuttle migration in a wider spectrum of rural municipalities in regard to endogenous approach to local development.

The RAPD analysis of several cultivars of grapevine (Vitis viniferaL.) and their clones

H. Vlastníková, K. Moravcová, M. Pidra

Hort. Sci. (Prague), 2004, 31(4):136-139 | DOI: 10.17221/3807-HORTSCI

Nine identification RAPD markers (Moravcová et al. 2003) were used to distinguish 24 clones and grapevine cultivars. No polymorphism was detected among all the tested clones of Chardonnay, Pinot gris and Zweigeltrebe from Polešovice. Pinot noir, Pinot gris, Pinot blanc and Pinot Meunier were indistinguishable within clones, they also showed the identical RAPD profile within cultivars (except discussed sample No. 26). On the other hand, Auxerrois as a relative to cultivars of Pinot group showed unique patterns and may be classified as a different cultivar. Some irregularities within the cultivars of Pinot family from Oblekovice were also found, several of them gave different results from those expected: Pinot blanc sample 26 has the RAPD profile typical of Chardonnay. A new abnormal RAPD pattern as a marker of typical Chardonnay and Pinot profiles was observed in two cases. While RAPD banding patterns could not distinguish between the known clones, they were useful for distinguishing between phenotypically similar cultivars and for assessing the origins of cultivars thought to have originated as sports.

P. Čermák, J. Glogar, L. Jankovský

J. For. Sci., 2004, 50(1):24-30 | DOI: 10.17221/4597-JFS

The paper deals with the determination of the rate of damage by deer barking and browsing, the subsequent rot caused by Stereum sanguinolentum and the rate of its progress, elucidates causes of damage and quantifies volume and financial losses in the region of Forest Range Mořkov, Forest District Frenštát pod Radhoštěm. In the most damaged 2nd age class, decay by Stereum sanguinolentum was recorded in 59% of damaged trees. The progress of rot ranged from 1 to 70 cm/year. The high number of red deer is considered to be the main reason of extensive damage by bark stripping in the Forest Range Mořkov. The actual financial loss caused by depreciation of wood by the rot is greatest in the 5th age class amounting to CZK 64,320 per ha.

Forestry, mountain catchments and floods in the Czech Republic

M. Bíba, J. Jiřík, K. Vančura

J. For. Sci., 2004, 50(11):538-541 | DOI: 10.17221/4653-JFS

A short introduction of historical overview and current situation refer to forestry problems of the country. Local climate is characterized and impacts of natural phenomena are described, as well as the impacts of human beings. The influence of forest management is mentioned and discussed in relation to latest catastrophic floods. The territory of the Czech Republic is damaged especially by a high intensity of atmospheric precipitation abnormal values which lead to a local or regional damage. In the catchment areas of torrents, damage leads to faster soil erosion, development of ravines, landslides, moving of soil sediments and their deposition, devastation of watercourse beds and properties, flooding while the flooding rates of flow represent a danger for the life of inhabitants. Important elements and results of respective research are described in brief. E.g. research of precipitation and its relation to the runoffs in the small mountain catchment areas with the forest stands restoration, as well as the forestry-hydrologic monitoring of forest environment, which has been taking place since 1928, and tradition of the service for torrent control. Forestry-hydrologic research gradually documents that a favorable flood-control performance of forest is limited. However, this is not a reason for not taking care of flood-control measures in the mountain afforested areas. These measures and importance of forest for the protection of land are historically verified and justified. In closing the mankind behavior to the landscape is underlined as a question mark.

R. Singh, R.K. Behl, K.P. Singh, P. Jain, N. Narula

Plant Soil Environ., 2004, 50(9):409-415 | DOI: 10.17221/4052-PSE

The present investigation was conducted to know the impact of bio-inoculants in low input field conditions on the magnitude and direction of gene effects and mean performance of some morphological and productivity traits in three wheat cultivars WH 147 (medium mineral input), WH 533 (drought tolerant), Raj 3077 (drought tolerant) and six generations namely P1, P2, F1, F2, BC1 and BC2 of three crosses i.e. WH 147 × WH 533, WH 533 × Raj 3077 and WH 147 × Raj 3077. The experiment was conducted in randomised block design with three replications and three treatments i.e. control (C, without inoculation), inoculation with arbuscular mycorrhiza fungi (AMF, Glomus fasciculatum), and AMF + Azotobacter chroococcum (Azc). Mineral fertilizer (80 kg N/ha + 40 kg P/ha + 18 kg ZnSO4/ha) was applied in all the three treatments. The application of bio-inoculants, AMF and AMF + Azc had a positive effect on plant height, peduncle length, grain yield, biological yield and harvest index in various populations of all the crosses. However, in some of the generations the impact of bio-inoculants was insignificant. The joint scaling test revealed that additive-dominance gene effects were mainly operative in governing expression of peduncle length, tillers per plant, plant height, grains/spike, grain yield and all traits except days to flowering and harvest index in crosses WH 147 × WH 533 and WH 533 × Raj 3077. The application of bioinoculants influenced gene effects for days to flowering, days to maturity, flag leaf area, spike length, grains/spike, 1000 grain weight and harvest index where complex genetic interactions were changed to simple additive-dominance gene effects in the cross WH 147 × Raj 3077. Likewise, additive-dominance gene effects were altered and digenic interactions exhibited for days to maturity, flag leaf area in WH 147 × WH 533 and days to flowering, plant height, flag leaf area in WH 533 × Raj 3077. Flag leaf area and plant height were governed by additive gene effects while for days to maturity and 1000-grain weight both additive and dominance gene effect were important. Duplicate epistasis was important in all the three crosses for days to flowering and harvest index and in the cross WH 147 × Raj 3077 for grain weight grains per spike and flag leaf area.

I. Pauhofová

Agric. Econ. - Czech, 2004, 50(4):161-168 | DOI: 10.17221/5184-AGRICECON

The objective of the article is to describe the possibilities of the rural development in the Bratislava region. The rural region is represented by 71 municipalities in districts Malacky, Pezinok, Senec and by parts of the city Bratislava - Záhorská Bystrica, Vajnory, Jarovce, Rusovce and Čunovo. The analyses of the rural region are the segments of the Single Programming Document (SPD) for the 2004-2006. It aims to support the areas with the main economic and social problems according the Goal 2. The article deals with the development possibilities in industry, market services, tourism and agriculture. The branch structure, main economic parameters of effectiveness and production, employment, wages are analysed in period 1999-2002. The article contains also the results of SWOT analysis and the short-term activities to supporting rural development.

Forming of the agrarian services in Slovakia in the process of European integration

I.M. Zoborský

Agric. Econ. - Czech, 2004, 50(8):359-364 | DOI: 10.17221/5217-AGRICECON

The paper analyses formation of specialized activities of Slovak agrarian services. The paper focuses attention on the definition of agrarian services, evaluation of their position and progress of their transformation, their quantitative development and distribution in the regions of the Slovak Republic, as well as on their economic results during the period from 1995 to 2001. Biological, technical, and other specialized services significantly influence the reproduction process of the plant and animal production even in the period of European integration.
