| O objetivo deste trabalho foi avaliar o vigor e a produtividade do maracujazeiro-amarelo plantado em diferentes tamanhos de cova e plantio direto sob manejo orgânico. O experimento foi conduzido de 2005 a 2007, no Setor de Agricultura Ecológica da Universidade Federal do Acre, em delineamento de blocos casualizados, constituídos de cinco tratamentos, quatro repetições e quatro plantas por parcela. Foram avaliados cinco tipos de preparo do solo: T1 cova do tamanho do torrão (0,19 x 0,063m) com adubação em cobertura; T2 cova de 0,30 x 0,30 x 0,30m com adubação de plantio na cova; T3 cova de 0,30 x 0,30 x 0,30m com adubação de plantio em cobertura; T4 cova de 0,50 x 0,50 x 0,50m com adubação de plantio na cova; e T5 cova de 0,50 x 0,50 x 0,50m com adubação de... |

| Twenty-two scab-resistant apple cultivars were harvested in autumn 1999 and evaluated for sensory quality the following October, November and December. Multivariate analysis was effective in describing the comblex relationships and variabillity among the numerous attributes used to characterise apple quality. Crispness, mealiness, skin toughness, apple flavour, sweetness, unripe flavour and overripe flavour were informative attributes describing the variation in the sensory quality. Texture attributes, apple flavour and overripe flavour were affected by storage. Extended storage resulted in an increase in mealiness and overripe flavour and a decrease in crispness, juiciness and apple flavour. Many potential scab-resistant cultivars were suitable for... |

| Die Resultate mit den "älteren" resistenten Apfelsorten bestätigen einerseits die bisherigen Erfahrungen; brachten aber auch interessante neue Erkenntnisse: 1. Das Potenzial der resistenten Sorten, um mit nicht-resistenten sensorisch und auch vom Äussern her mitzuhalten, ist absolut gegeben. 2. Die einzelnen Kandidaten haben ihre bekannten Stärken und Schwachpunkte (z.B. Ariwa oder Topaz). Dem ist in der Produktion mit sorgfältigem Einhalten der wichtigsten Massnahmen zu begegnen: a) Genügende Ausdünnung schon ab Blüte bis vor der Ernte, b) korrekter Erntezeitpunkt (Streifindex 029-0.12 bei Ariwa und 0.17-0.10 bei Topaz); c) tadellose Lagerung und frühzeitiger Verkauf. 3. Ecolette konnte mit sehr guten Resultaten im Aussehen und im Geschmack frühere... |

| Orchard floor management impacts soil conditions and thus tree performance. This research was initiated to investigate the effects of alternative orchard floor management systems compatible with organic production on soil parameters using the“Pacific Gala” apple cultivar (Malus × domestica Borkh.) on three rootstocks of varying vigor. Alfalfa hay mulch, propane flame burner, and Swiss sandwich system(combination of resident vegetation and tilled strips)were compared from 2001 to 2005. These treatments were applied to tree rows which provided different vegetation-free areas. Contrasting additions of organic matter were evaluated for their effect on soil organic matter (SOM), C content, nitrate and ammonium availability, moisture, and soil food web through... |

| 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,... |

| Objetivou-se, neste trabalho, avaliar o efeito da quitosana no desenvolvimento in vitro de plântulas de videira cv. Merlot e sua atividade antifúngica sobre Elsinoe ampelina. No primeiro experimento, explantes da cultivar Merlot foram transferidos para meio de cultura DSD1, acrescido das concentrações 0; 25; 50,100; 150 e 200 mg L-1 de quitosana. Após 90 dias de cultivo in vitro, as plântulas foram avaliadas quanto ao número de raízes e de folhas, porcentagem de enraizamento e brotação, comprimento de raízes e de parte aérea, massa fresca da planta. No segundo experimento, incorporou-se às concentrações 0, 60, 120, 180, 240 e 300 mg L-1 de quitosana ao meio BDA, onde inoculou-se o fungo. Posteriormente, avaliou-se o crescimento micelial aos 6 e 9 dias de... |

| The use of scab resistant apple varieties is the best way to prevent infections of apple scab (Venturia inaequalis). In 1995 the then 10 most promising resistant apple varieties for Denmark where planted at Research Centre Årslev, Denmark in an organic production system. Tree different cover crops where established in the allyways. Weed cleaning in the tree row was done mechanically and the trees were kept unfertilised. The annual shoot growth, nutrients in leaf sample, mineralised nitrogen in soil, content of water in the upper 50 cm soil, fruit yield and fruit quality were assessed. The best fruit quality due to colour, pest and disease damage was obtained in trees grown in permanent grass alley way system which gave a nitrogen sypply in the lower end... |

| Mainly in Anglo-Saxon countries (USA, New Zealand etc.) the market for organic agriculture inputs offers different natural substances for the use as bio-herbicides. The most important ingredients of these products are acetic acid, citric acid and clove-extracts (eugenol) in the case of post-emergence herbicides and corn-gluten in pre-emergence products. In a first screening test we compared the efficacy of these ingredients with some other natural substances. The most interesting ones were later compared in a field trial where the efficacy and the required dosages to clean a strip of about 40 cm under the trees were assessed in an ap-ple orchard. A few products showed interesting results (vinegar, pine oil), but the required dosage to keep the strip under... |
