Bilan et perspectives de la Recherche en Agriculture Bio-dynamique Organic Eprints
Turinek, Matjaž; Grobelnik Mlakar, Silva; Bavec, Franc; Bavec, Martina.
L’Agriculture Biodynamique (BD) a été l’objet de nombreux efforts de recherches durant les dernières décennies, bien qu’une partie de la communauté scientifique regarde les méthodes biodynamiques avec scepticisme et les considère comme dogmatiques. Néanmoins, comme cela est montré dans cet article de synthèse, une part non négligeable des résultats présentés dans des revues scientifiques à comité de lecture et issus d’expérimentations contrôlées de plein champ, ou d’étude de cas, montrent des effets des préparations biodynamiques sur le rendement, la qualité du sol et la biodiversité. De plus, les préparations biodynamiques ont un impact environnemental positif en termes d’utilisation et d’efficacité énergétique. Cependant, le mode d’action mécanique des...

COMPETITIVE ABILITY OF MAIZE IN MIXTURE WITH CLIMBING BEAN IN ORGANIC FARMING Organic Eprints
Bavec, Franc; Živec, Urška; Grobelnik Mlakar, Silva; Bavec, Martina; Radics, Laszlo.
Intercropped crops represent an important production system in organic farming, especially maize/climbing bean mixture due to its high content of protein in bean seeds for human diet, and producing silage for ruminants. To test this hypothesis, the effects of maize (Zea mays L.) sown as a sole crop and maize/climbing bean (Phaseolus vulgaris L. cv. Cipro) mixtures on maize plant height, maize leaf area index, bean leaf area index and grain yield were investigated in field experiments on an organic farm following accepted rules of certification. The maize/climbing bean mixture increased maize plant height as well as maize and bean leaf area and reduced maize grain yield in comparison with maize sown as sole crop, but 477.5 kg ha-1seed yield of bean sown in...

Cost and energy evaluation of organic cauliflower in sole crop and living mulch systems Organic Eprints
Ortolani, Livia; Kristensen, Hanne L.; Campanelli, Gabriele; Bavec, Martina; Bavec, Franc; von Fragstein, Peter; Bergmam, Astrid; Leteo, Fabrizio; Canali, Stefano.
This paper presents the findings of an assessment aimed to evaluate, in terms of cost and energy consumption, the introduction of living mulches in different organic vegetable systems producing cauliflower. The study was carried out in three European countries (IT, SLO and DK) in the frame of the InterVeg project (Core Organic II). The achievements demonstrated that, in economic terms, farmers’ choice of a specific technique, like living mulch instead of sole cropping, can be influenced by two key elements: human labor and fossil fuel consumption. Different organic systems have a different proportion in using the two inputs depending on the specific farm strategy.

ECOLOGICAL FOOTPRINT AS A METHOD FOR EVALUATION DIFFERENT AGRICULTURE PRODUCTION SYSTEMS Organic Eprints
Bavec , Martina; Štraus, Saša; Turinek, Matjaž; Narodoslawsky, Michael; Robačer, Martina; Grobelnik Mlakar, Silva; Jakop, Manfred; Bavec, Franc.
Ecological footprint could be a tool for evaluating impacts of different agricultural production systems (PS). Based on more years field experiments producing vegetables and field crops cological footprint of conventional (CON), integrated (INT), organic (ORG) and biodynamic (BD) farming systems in Maribor and CON, INT and ORG in Dolenci was calculated and interpreted using the SPIonExcel tool. Results showed a markedly lower ecological footprint of ORG and BD systems compared to CON and INT which are not significantlly different. Identified were possibilities for reducing ecological footprint – for CON and INT by reducing mineral fertilizers and pesticide inputs; for ORG and BD by changing fuels and reducing maschinery use.

EFFECT OF AN IN-SEASON LIVING MULCH ON LEACHING OF INORGANIC NITROGEN IN CAULIFLOWER (BRASSICA OLERACEA L. VAR. BOTRYTIS) CROPPING IN SLOVENIA, GERMANY AND DENMARK Organic Eprints
Kristensen, Hanne Lakkenborg; Campanelli, G.; Bavec, Franc; von Fragstein und Niemsdorff, Peter; Canali, S.; Tittarelli, F..
Vegetables with a high nitrogen demand such as cauliflower may cause intensive leaching of nitrate to the environment in conventional as well as in organic production. In organic cropping systems, the use of an in-season living mulch may decrease the risk of nitrate leaching after harvest when left growing in the field to the end of the leaching season in spring. The aim of this study was to investigate the effect of growing an in-season living mulch including legumes on the risk of leaching of inorganic nitrogen over winter, and soil nitrogen availability the following spring. Three field experiments were carried out in Slovenia, Germany and Denmark in the frame of the Interveg project (CORE organic II). Evaluation of soil inorganic nitrogen content was...

EFFECT OF LIVING MULCH ON PEST/BENEFICIAL INTERACTION Organic Eprints
Burgio, Giovanni; Kristensen, Hanne L.; Campanelli, Gabriele; Bavec, Franc; Bavec, Martina; von Fragstein und Niemsdorff, Peter; Depalo, Laura; Lanzoni, Alberto; Canali, Stefano.
The aim of this study was to evaluate the effect of cover crops on pest/beneficial dynamics and to test the potential of living mulch on enhancing biological control against insect pests. The research, carried out in the frame of the InterVeg (Core Organic II) project, involved four European countries: Germany, Slovenia, Denmark and Italy. Three crops were tested: cauliflower, leek and artichoke. The preliminary results obtained in Italy on cauliflower, indicated that the living mulch did not affect the infestation of the cabbage butterfly, Pieris brassicae, showing no detrimental effect of this technique on pest dynamics. A very high level of parasitization against cabbage butterfly was detected either in the living mulch crop (88%) and in the sole one...

Living mulch and vegetable production: effect on crop/weed competition Organic Eprints
Ciaccia, Corrado; Kristensen, Hanne L.; Campanelli, Gabriele; Bavec, Franc; von Fragstein, Peter; Robacer, Martina; Testani, Elena; Canali, Stefano.
Two field experiments were carried out in order to test the effect on weed management of living mulch introduction in organically managed cauliflower in Central Italy and leek in Denmark. Burr medic and Dyers Woad were sown as living mulch in Central Italy and Denmark, respectively. Different living mulch managements and cultivars were tested in strip plot designs. The main objective of the research was the evaluation of their effects on both crop growth and weed suppression. Biomass of crops, living mulches and weeds were measured and competitive indices were used to assess their competitive relationships. The results showed the effect of the agronomic choices (interseeding timing and crop cultivar) on weed suppressiveness and in avoiding living mulch...

The knowledge transfer from science to practice – a survey with EU researchers Organic Eprints
von Fragstein und Niemsdorff, Peter; Briz, Teresa; Bavec, Franc; Batista, Joao; Moudry, Jan; Moudry, Jan, Jr.; Konvalina, Petr; Luik , Anne; Matt, Darja; Basile, Salvatore; Langeveld, Cor; Jansen, Bernhard; Nikolova, Svetla; Mynttinen, Rytva; Hytönen, Anne; Mancinelli , Roberto; Radics , Laszlo; Kazimierczak, Renata; Rembialkowska, Ewa.
Group members came from 12 European countries, six from new (Bulgaria, Czech Republic, Estonia, Hungary, Poland and Slovenia) and six from old EU member states (Germany, Spain, Finland, Italy, The Netherlands, Portugal). The aim of the work was to analyze the role of the scientists in a dialogue between them and the practitioners within the organic production sector. Another important aim was to find the best practice models of such dialogue as the examples to be followed by others. In order to reach this aim the survey with the scientists has been conducted by all project partners; every partner has conducted the survey with 10 selected scientists from own country. Only the scientists possessing PhD level and actively working in the organic sector...
