| Analisou-se a relação entre o efeito do plantio de diferentes espécies vegetais, em bordadura, na cultura da cebola, Allium cepa L, na incidência de Thrips tabaci Lind. e sirfídeos predadores, Toxomerus spp. O experimento foi conduzido na Epagri, EE de Ituporanga, de agosto a dezembro de 1998. Os tratamentos foram cebola em monocultivo; cebola + trigo mourisco (Fagopyrum esculentum Moench); cebola + nabo forrageiro (Raphanus sativus L. var. oleiferus Metzg.); cebola + cenoura (Daucus carota L., cv. Nantes e cv. Brasília); cebola + milho (Zea mays L.); cebola + rúcula (Eruca sativa L.) + vegetação espontânea. O plantio de diferentes espécies vegetais em bordadura não provocou diferenças significativas na incidência de tripes e sirfídeos predadores. A... |

| The aim of this work was to obtain a number of complete soluble compost extracts rich in micronutrients, which can safely be used for fertigation through modern irrigation systems in organic farming system. Evaluation of their effects was conducted on potato crop var. Draga and soil fertility. During the extraction experiment two different composts (Farm compost and Commercial compost) were treated with water to obtain following dilution ratios: 1:5, 1:10, 1:20. Most chemical parameters of the compost extracts generally reflect the chemical composition of the starting material. These six dilutions were applied during the growing season. The control shows the highest tuber yield (22.1 tons/ha) followed by FC20 treatment (21.03 tons/ha). The number of tubers... |

| It is well-known that compost and manure applications to all kinds of soils if these organic materials are mature and composted under favorable conditions result in improved soil fertility and crop production in terms of yield and quality, but because manure is expensive in our region and the application of in-farm production compost for organic lands and farms of Turkey is limited, there is a great and urgent need for demonstrate compost using advantages to soil fertility, plant yield-quality and food safety (Kir 2006). Vegetables account for only approximately 2% of total organic production in Turkey, but there is great potential for growth of organic production for both export and domestic consumption of organic products in our country. Lettuce (Lactuca... |

| Con el objetivo de evaluar el impacto de la aplicación de biosólidos de aguas residuales urbanas en la concentración de metales pesados (MP) en el sistema suelo-planta y la composición microbiológica del suelo, se realizó el presente trabajo en el Instituto Nacional de Ciencias Agrícolas (INCA), La Habana, Cuba. La aplicación de biosólidos en el suelo Ferralítico Rojo compactado incrementó el contenido cobre (Cu), níquel (Ni) y cinc (Zn) en los sustratos; mientras que, el contenido de hierro (Fe) y manganeso (Mn) disminuyó, comportamiento que mantuvo la misma tendencia al evaluar los diferentes órganos de las plantas. Se destaca que las concentraciones de MP encontradas en los sustratos y los órganos vegetales no representaron riesgos de fitotoxicidad ya... |

| Im ökologischen Gemüsebau werden hohe Nährstoffmengen benötigt, um qualitativ hochwertiges Gemüse zu produzieren. Der Nährstoffbedarf kann bisher nicht ausreichend durch ökologisch erzeugte Düngemittel gedeckt werden. Zum Einsatz kommen überwiegend organische Reststoffe aus der konventionellen Landwirtschaft. An dieser Stelle setzte das Forschungsvorhaben mit dem Ziel an, ein stickstoffreiches Düngemittel aus Futterleguminosenschnittgut für den ökologischen Gemüsebau zu entwickeln und in Spinat und Rote Rübe zu erproben. Es sollte junges Schnittgut mit einem C/N-Verhältnis von ≤ 10 geerntet werden, welches nach Einarbeitung in den Boden schnell mineralisiert. Die Untersuchungen gliederten sich in vier Teile. Im ersten Teil der Arbeit wurden in... |

| The paper examines the profitability of twelve polytunnel vegetable crops grown for an organic box scheme in Scotland. All inputs attributable to specific crops, labour in particular, were recorded during 2008 growing season and expressed in monetary values. Costs of the tunnel construction and maintenance have also been included. Based on sales data and inputs, annual net margins were calculated. Assuming the cost of labour as 7.25 £/hour only five of twelve vegetables were profitable. Results varied from 25.2 £/m2/year for cucumbers to -9.7 £/m2/year (loss) for batavian lettuce, average for all the crops was 3.38 £/m2/year. No significant difference in profitability could be ascertained between the following cultural methods: direct sown versus... |

| Bedingt durch die politische Entwicklung der letzten Jahre hat der ökologische Anbau in Deutschland an Bedeutung gewonnen. Für eine Ausdehnung, bzw. Förderung des ökologischen Anbaus fehlen allerdings Daten, die umstellungsinteressierten Betrieben bei der Entscheidungsfindung behilflich sein können. Ebenso fehlen ökologisch wirtschaftenden Betrieben Daten zur Kontrolle der eigenen Leistung. Diese Datensammlung hat zum Ziel, Kosten-Leistungsrechnungen zu typischen Produktionsverfahren der zehn wichtigsten Kulturen des ökologischen Gemüsebaus in Deutschland bereitzustellen, um so die genannten Informationslücken zu schließen. Die zehn in Bezug auf die Fläche und den Umsatz wichtigsten Kulturen wurden durch Berater des ökologischen Gemüsebaus... |

| Until now starch and its metabolites malto-oligosaccharides have been overlooked as potentially important constituents of carbohydrates in carrots. A comparison of the organically bred cultivars Rodelika and Robila with the hybrid cultivars Maestro F1 and Starca F1 revealed that the content of malto-oligosaccharides in the organic cultivars (126 and 191 mg g-1 dry matter, respectively) surpassed the content in the two hybrid cultivars (86 and 89 mg g-1 dry matter, respectively), although the starch content was similar in all cultivars (between 50 and 70 mg g-1 dry matter). There were also cultivar differences in the pattern of glucose, fructose, and sucrose, however, the total amount of water-soluble carbohydrates (between 550 and 600 mg g-1 dry... |

| Four old and endangered tomato cultivars were cultivated under greenhouse conditions with different levels of organic N-fertilisation and harvest at different maturity stages in order to develop a conclusive concept to preserve the diversity of old, endangered and multicolour cultivars. First results of several physio-chemical and sensory parameters were analysed to describe product quality. In order to assess consumer acceptance, 550 consumers were interviewed. The individual attributes of the cultivars, which differ in size, shape, colour, taste and health-related, beneficial physio-chemicals, are promoted by optimal harvest time. A combination of these cultivars distributed in regional markets is considered as a suitable concept for saving these... |

| Ved produktion af tomater er der behov for tilførsel af store mængder gødning. Ved økologisk dyrkning kan tilførsel af store mængder organisk gødning medføre risiko for udvaskning. Når planter år efter år dyrkes i den samme jord i væksthus er der en risiko for angreb af jordbårne sygdomme; en risiko som ikke kan forebygges ved sædskifte. Et nyudviklet dyrkningssystem ved DJF Årslev har vist at disse problemer kan undgås. Dyrkningssystemet udnytter fordelene ved både dyrkning direkte i jord og dyrkning i afgrænsede bede. Resultaterne fra forsøget viser at det er muligt at dyrke tomat og opnå helt tilfredsstillende udbytter ved dyrkning i kompost i halvåbne bede hvor det er muligt at recirkulere overskudsvand og genanvende komposten som... |

| Aims: * To quantify the balance between UK demand and supply for the main organic vegetable crops and discover levels of UK market share * To identify opportunities for UK growers * To provide a clearer picture of the market for growers, marketers and policy makers * To enable monitoring of progress towards national targets Background: During the late 1990s and early 2000s the organic vegetable market in the UK was reported to be growing at an average of 30 per cent per annum. However by 2002-03 growth has begun to slow to about 20 per cent per year. The market had also started to stabilise with less peaks and troughs in supply, better relationships in the supply chain, much less speculative growing and UK self-sufficiently rose to 59 per... |

| Eines der Probleme des Ökologischen Gemüsebaus ist die adäquate Versorgung der Kulturen mit Stickstoff. Bei dem Umgang mit der Stickstoffdüngung kann man mehrere Problemfelder unterscheiden: - eine ausreichende N-Versorgung bei anspruchsvollen Kulturen - die sachgerechte Kalkulation der N-Düngung in Abhängigkeit vom Bedarf der Pflanze - mögliche N-min Rest am Ende der Kultur im Boden Bei der Evaluierung der Kalkulation zeigte sich, daß die Beziehung zwischen dem Ertrag und dem kalkulierten N-Angebot bei Kohl und Spinat eng war. Es zeigte sich außerdem, daß die Nachlieferung aus der Gründüngung in der Regel überschätzt worden war, während die aus dem Humus in der Regel unterschätzt worden war. Außerdem zeigte sich, dass es erforderlich ist, weitere... |

| As práticas agrícolas que maximizam a produtividade e o uso da água são de vital importância para a agricultura. Assim, foram testados três tipos de manejo do solo com objetivo de determinar a evapotranspiração (ETc) e os coeficientes de cultivo (kc) da beterraba. Os tipos de manejo foram a utilização de coberturas mortas vegetais, denominadas capim cameroon (Pennisetum purpureum), gliricídia (Gliricidia sepium) e solo sem cobertura morta em área experimental do SIPA (Sistema Integrado de Produção Orgânica) localizado em Seropédica, Brasil. A lâmina de irrigação foi estimada com base no balanço de água no solo, cujo monitoramento foi realizado com a técnica da TDR. As ETc acumuladas para a cultura da beterraba foram 59,41; 55,31 e 119,62 mm,... |
