Species cultivar choice

At the same time, many organic farmers look for, and find, solutions to many of the technical problems they face. Choice of crop species and cultivar, choice of animal breed and race, sequence of crops in rotation and duration of rotation, etc., are all options to decrease the importance of certain technical problems. [Pg.234]

Before the establishment of organic orchards, it is essential to consider practical experience and local knowledge about the most suitable sites and microclimatic conditions (reviewed bv Webster, 2005 Barden and Neilson, 2003) as well as species and cultivar suitability. These factors should be considered before planting orchards, because it is more difficult than in conventional production to overcome problems associated with poor choice of site and variety/cultivar. However, some site-specific problems may be addressed within certain limits (e.g. suboptimal soil conditions) and should be improved before planting a new orchard (e.g. installation of drainage to prevent temporary water logging,... [Pg.332]

Important intrinsic quality criteria currently determining the market potential of new apple cultivars are related to the sensory quality such as fruit firmness (crispness) and the sugar and acidity contents. On the other hand, the nutritional composition (e.g. the vitamin or antioxidant contents) is currently not used as a criterion in the choice of cultivars, neither in conventional nor in organic fruit production. The difference in the content of such components between fruit species is in most cases more relevant than between cultivars of the same species (e.g. vitamin C content of oranges versus apples). [Pg.333]

Many diseases and even insects can be controlled by growing resistant or tolerant cul-tivars or. species. By emphasizing disease resistance in your choice of cultivars, you can completely avoid some common pest problems. For example, some newer cultivars of shell pea, including Maestro , are resistant to mosaic virus as well as powdery mildew and Fusarium wilt. Similarly, Slicemaster cucumber resists both downy mildew and powdery mildew, plus leaf spot, anthracnose, and mosaic virus. [Pg.410]
