| In der Ökologischen Landwirtschaft basiert die Fütterung der Nutztiere vorrangig auf der Nutzung wirtschaftseigener Futtermittel. Die Maispflanze kommt mit dem hohen Energieertrag pro Fläche der begrenzten Verfügbarkeit von energiereichen wirtschaftseigenen Futtermitteln sehr entgegen. In der konventionellen Schweineproduktion beschränkt sich die Nutzung der Maispflanze weitgehend auf die Fütterung von Corn-Cob-Mix (CCM). Wertgebender Inhaltsstoff ist dabei die Stärke, welche den hohen Gehalt an Umsetzbarer Energie (ME) von bis zu 16 MJ/kg T bedingt. CCM findet insbesondere in den Bundesländern Nordrhein-Westfalen und Niedersachsen eine breite Anwendung auf spezialisierten Schweinemastbetrieben. Die Fütterung von CCM setzt einen hohen Grad der... |

| During the last years damage caused by plant parasitic nematodes in organic field vegetable farming has been observed with increasing attention. A general inquiry was started on farms with nematode problems to collect information about infestation, crop rotation and control strategies. Soil samples from 207 vegetable fields were taken from 55 farms in Germany and the detected nematodes were analysed. Seventeen different genera of plant parasitic nematodes were found. Nematodes of the genus Pratylenchus were found on 90 % of Meloidogyne on 50 % of the analysed fields - these two are the most important genera that damage vegetables. More than half of the infested fields were of sandy soils. Yield reductions of 50 % could be observed on 40 % of the fields... |

| The 2010 growing season was exceptionally warm and most cultivars performed well, except Sovereign and Sedley that lodged and matured late. There were significant differences in earliness (P<0.001), the earliest cultivar being Rosetown (901 GDD to maturity), and the latest Sedley (1214 GDD). There were no significant differences in yield (P=0.111), the average being 1.49 t/ha. Cultivar Meteor was the highest yielding with 1.86 t/ha but it lodged, whereas cvs Redbow, Redcoat, Rosetown and Milestone yielded between 1.5–1.6 t/ha and showed few problems in cultivation, so further experiments will focus on them. In conclusion, lentil cultivation is feasible in Finland, and further trials will be run in 2011. |

| Abstract - In our research we have evaluated a series of soil indicators to determine the correlation between individual soil properties in organic farming. Regression analysis has proven that the biological activity of the soil on organically farmed areas (grasslands) as expressed by respiration is mainly influenced by the bulk density, moisture, porosity, humus content, the proportion of cation exchange capacity and total nitrogen content. The multiple regressions have proven the important dependency of basal respiration to the moisture, bulk density and total nitrogen. The supply of organic matter to the soil environment, thus greatly influences the studied soil biological activity. Similar dependences were visible in the results of both conventional... |

| Energy production and energy use in organic agriculture (OA) need to be addressed in order to reduce the reliance on non-renewable fossil fuels and minimize greenhouse gas (GHG) emissions. Thus, there is an obligation to find consensus between the apparent opposing aims of renewable (bio) energy production and soil fertility in OA. This project aims at designing and evaluate a combined concept for biomass and bio-energy production in OA, while considering soil fertility. |

| A field was carried out on an ultisol in humid area of Edo State, Nigeria to evaluate the effects of plant density and cattle dung manure application on soil nutrient status and okra pod yield. Treatments consisted of three levels of cow dung (0, 300 and 450 kg N ha-1) and three plant densities (47,619, 66,666 and 83,333 plants per hectare (pph)). A 3 x 3 factorial arrangement fitted into randomized complete block design and replicated three times. Data were collected on soil chemical properties and pod yield of okra. Routine analysis of the soil indicated that the soil was low in nutrient content, thus addition of cattle dung to the soil at various levels influenced the soil nutrient status positively. After cropping with okra, cattle dung application had... |

| - Berries, juice and other products of organically cultivated sea buckthorn (Hippophae rhamnoides L., Eleagnaceae) are in great demand because of their beneficial health effects. The availability of berries is not sufficient especially for locally growing market. However no research has been done on the effects of farming methods on the quality of sea buckthorn tissues before. We established a field experiment to study the effects of organic farming methods on the concentra-tions of phenolic compounds in leaves of two Finnish sea buckthorn cultivars ”Terhi” and ”Tytti”. 560 one and half years old seedlings were planted into 9 spatial blocks in coastal area in Merikarvia, western Finland in 2003. Different fertilizers and mulches were applied to the... |

| Unsustainable farming practices, including soil tillage intensification and heavy use of agrochemicals, have an adverse impact on natural resources, biodiversity and the environment. Therefore, there is a need to improve actual agricultural practices. The introduction of living mulches could be an efficient tool in order to stabilize crop yields, improve soil characteristics, and reduce external agricultural inputs such as herbicides and fertilizers. The overall objective of this experiment is to improve understanding and use of subsidiary crops in conservation agriculture systems under the Mediterranean environment of central Italy. Field experiment was set up in September 2012 at the experimental farm of Tuscia University (UNITUS). A 2-year durum... |

| In Italy, as in other countries, Organic Food and Farming (OFF) research suffers of a very high fragmentation being carried out by many public research institutes, Universities and private centres. In more recent years, due to the increasing relevance of OFF within national rural development programmes strong efforts have been addressed towards an improvement of the efficiency of the fundings distribution, the research system and its activity reorganization, and a reduction of overlapping initiatives. A view on projects and institutions currently working on OFF research in Italy is presented, mainly focusing on the available public financial instruments and the main projects funded by MIPAF. Most of the Italian research projects investigates plant... |

| This report was presented at the UK Organic Research 2002 Conference. Land emissions of N2O, CO2 and NH3 have been subject to little study under organic systems, yet form important aspects of sustainability of such systems. We describe innovative methods developed at SAC to assess trace gas emission using both automatic closed chamber systems (intensive, short term monitoring) and manually-operated closed chamber systems (occasional, long term monitoring). Long-term data were collected from organic ley-arable rotation trials in North-east of Scotland. Short term data were collected to show the effect of timing and depth of ploughing-out of the ley phase on gas emissions. Ploughing gave a shortterm stimulation of CO2 and, more markedly, of N2O emission.... |

| In view of climate change predictions and the general desirability of increasing the amount of home grown protein, a case exists for the investigation of lupins and lupin/cereal bicrop combinations as wholecrop forage on organic farms. A replicated randomised block trial is described which took place at the Royal Agricultural College, Cirencester, in 2005. This involved spring sown blue, white and yellow lupins, millet, wheat and triticale and lupin/cereal bi-crops. Data for dry matter yields for wholecrop silage, crude protein, MAD fi bre content and estimated ME, are presented for a single harvest. It is concluded that white lupins and white lupin bi-crops with spring wheat or triticale offer the best prospects for a viable wholecrop forage crop in an... |

| Legume foot and root diseases are influenced by complex interactions of site, soil properties, seed health, cropping sequence and climate. Crop rotation, cover crops and organic matter management are the key management tools in the dealing with the increase pathogen pressure. Application of high quality composts and other organic amendments is potential ecologically friendly alternative to fungicide application for control of soil-borne fungal pathogens. In order to evaluate the potential of Yard Waste Compost (YWC) to suppress foot rot disease of pea caused by Didymella pinodes (syn Mycospharella pinodes), Phoma medicaginis, Fusarium solani f. sp pisi and F. avenaceum, a pot experiment was carried out under controlled conditions. The susceptible spring... |

| Eastern purple coneflower [Echinacea purpurea (L.) Moench.] is globally recognized as one of the most popular medicinal herbs. In the present study, the effects of incorporation of the plant residues of this medicinal plant on weed flora and early growth of a sunflower crop were investigated. A field and a pot experiment were conducted at the Agricultural University of Athens. The field experiment was conducted under organic conditions, while in the pot experiment the focus was on the early growth of sunflower plants under the effect of plant residues. The results showed that there was a significant effect of plant residues on weed flora and the producted biomass, especially during the first crucial growth stages of sunflower. Particularly, the... |

| Die Kombination von Weidehaltung mit automatischen Melksystemen (AMS) stellt besondere Herausforderungen an das Betriebs-, Fütterungs- und Weidemanagement. In der vorliegenden Arbeit wurden Ergebnisse und Erfahrungen von 10 österreichischen Bio-AMSWeidebetrieben erfasst. Der Kuhbestand der Betriebe war mit 36 Kühen gering, die AMS-Auslastung lag im Mittel bei nur 44 % (26 bis 60 %). Die Betriebe stockten den Kuhbestand nach Umstellung auf AMS auf und reduzierten das Weideangebot leicht (-12 %), jedoch wurden hier große Streuungen festgestellt (-50 bis + 60 %). Bei der Entscheidung auf das AMS umzustellen waren arbeitswirtschaftliche Überlegungen wichtiger als ökonomische Gesichtspunkte. Die Melkfrequenz lag mit 2,4 Melkungen pro Kuh und Tag während der... |
