| Organik tarımda temel ilkelerden biri işletme dışı girdiler yerine işletme içi girdilere dayalı olabildiğince kapalı bir sistemin kurulmasıdır. Bu açıdan yeşil gübreleme, organik tarım teknikleri arasında toprak verimliliğinin sağlanması açısından temel bir uygulamadır. Çalışma, ardı ardına yetiştirilen baklagil sebze türlerinin önceki baklagil türünden nasıl etkilendiğinin belirlenmesi amacıyla Ege Üniversitesi Ziraat Fakültesi Bahçe Bitkileri Bölümü deneme alanlarında 4 tekerrürlü ve bölünmüş parseller deneme desenine göre kurulmuştur. Bu amaçla 3 farklı baklagil sebze türü (bezelye, fasulye, bakla) birbiri ardına üretimde ülkemizde geçerli organik tarıma ilişkin kanun ve yönetmelikler izlenerek yetiştirilmiştir. Ayrıca bölünmüş parsellerde içeriği... |

| Auch im ökologischen Anbau von Tomaten, Paprika und Auberginen werden vermehrt veredelte Pflanzen eingesetzt. Am Markt werden für jede Kulturart verschiedene Unterlagen angeboten. Am Kompetenzzentrum für den ökoloischen Gemüsebau in Bamberg (Bayr. Landesanstalt f. Wein- u. Gartenbau) wurden in 2007 hierzu umfangreiche Vergleiche durchgeführt. Es zeigte sich, dass die Wahl der Unterlage eine massive Auswirkung auf den Ertrag haben kann. Nicht alle Unterlagen sind für den Bioanbau gleich gut geeignet. Bei der Auswahl der passenden Unterlage reicht es keinesfalls die Resistenzen zu betrachten, auch andere Faktoren müssen Beachtung finden. |

| In a field experiment, we evaluated effects of three different organic white cabbage-cropping systems (O1, O2, O3) on the cabbage root fly, Delia radicum, and its egg predators and pupal parasitoids over 3 years. The three systems all complied with regulations for organic production, but varied in external nutrient input and N-recycling, and were compared to a conventionally farmed control. One organic system (O3) included an intercropped strip of green manure between crop rows. Oviposition by D. radicum was generally not reduced in organic cropping systems. However, higher pupae/egg ratios were observed in the conventional compared to all organic systems, indicating that immature survival from oviposition to pupation was reduced under all the three... |

| Long-term trials on production of organic field vegetables at Wellesbourne and Kirton. Organic plots have been monitored from the start of conversion in 1995-6. A full cropping history and soil analysis data are available. Wide range of facilities and environments for field studies e.g. 20 ha in arable reversion cropped with various grass mixes and available for environmental and ecological studies. |

| Die Agrarökonomie als Wissensgebiet definiert sich durch den empirischen Gegenstand und einen Methodenkanon. Das institutionelle Netzwerk der Agrarökonomie erstreckt sich über Universitäten und Fachhochschulen, außeruniversitäre Forschungseinrichtungen, Verwaltungen, den gesamten agrarwissenschaftlichen Sektor und die verschiedenen Interessenverbände. Zu den Anforderungen des ökologischen Landbaus an die Agrarökonomie gehört zum einen ein Verständnis für das Gesamtsystem des Öko-Anbaus. Zum anderen besteht jedoch auch die Notwendigkeit der deskriptiven Forschung. Es müssen viele Zahlen, die im konventionellen Bereich bereits vorliegen, neu zusammengetragen werden. Betriebswirtschaftliche Forschung im Bereich des ökologischen Gemüsebaus gibt es bisher... |

| To manage weeds with reduced reliance on, or without herbicides, cropping systems require intervals during which rapid and significant reductions in the germinable portion of the weed seedbank occur or, if already small, management to maintain a low density. Cover cropping systems and component studies have identified single-season cover cropping practices that will lower the density of the germinable weed seedbank, offering an effective means for managing the weed seedbank while maintaining or improving soil health. Specifically, field experiments demonstrated that soil disturbance events associated with cover cropping encouraged germination and seedling establishment thereby reducing the density of germinable seeds in the weed seedbank. Of notable... |

| One core idea behind organic production is that cropping systems should be less dependent on resource import than conventional production and minimize negative environmental effects. This study aimed to test novel organic rotations, designed to reduce reliance on external resource import. We compared a conventional system (C) and an organic system relying on manure import (O1) to two rotations (O2 and O3), both relying on autumn cover crops for soil fertility, and in O3 green manure rows were left as intercrops. Resource import differed between 149, 85, 25 and 25 kg N ha-1 year-1 in C, O1, O2 and O3. Crop yields were lower in the organic systems (on average 82% of conventional yields), differing among crops, when based on the area grown with main crops.... |

| O objetivo deste trabalho foi avaliar a produção de mudas de tomate em três substratos sob irrigação com efluente de piscicultura. O experimento foi conduzido na horta do Departamento de Ciências Vegetais, na Universidade Federal Rural do Semiárido (UFERSA), Mossoró, RN. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 3 x 2, com quatro repetições, sendo os tratamentos constituídos pelas combinações tipos de substrato (Plantmax®, composto orgânico e areia lavada) com fonte de água de irrigação (efluente de piscicultura e água de poço). A avaliação foi feita aos 24 dias da germinação através de número de folhas, altura da parte aérea, comprimento da raiz principal, massa seca da parte aérea e massa seca do sistema radicular. O... |

| Conservation and enhancement of biodiversity are mentioned in the International Federation of Organic Agriculture Movements (IFOAM) standards and in all national guidelines as essential pillars for organic agriculture. Recent reviews show that organic agriculture enhances the number of species and the abundance of many taxa (plants, birds, mammals, earthworms, arthropods, soil microbes), compared with conventional agriculture. Considering the benefits for sustainability, a multi-criteria analysis shows that organic agriculture not only improves biodiversity but also has positive effects on soil (e.g., soil erosion, structure, biological activity), water (e.g., no pesticide residues) and climatic factors (e.g., air pollution). In organic horticulture,... |

| Mentha piperita commonly called the peppermint belong to the genus Mentha of the family Lamiaceae with over 200 genera distributed mostly in temperate and sub-temperate regions. It yields most popular and widely used essential oils. Preliminary study on peppermint as a new crop in Nigeria revealed a great potential for its adaptability and cultivation. Meeting nutrients requirement is one of the important agronomic conditions for successful introduction of new crops because it has a great influence on growth, the quality and quantity of secondary metabolites which directly or otherwise affect our health. A field experiment was conducted in 2016 at Federal University of Agriculture, Abeokuta (Latitude 7o 14ǀ 8.034 NS, Longitude 3o 26ǀ 13.914 EW and... |
