Cereal breeding strategies for organic and low-external-input crop production systems
Provedor de dados: 21
Autores: Acikgoz, Prof. Dr. Nazimi; Ilker, Dr. Emre.
Increasing trend in organic farming does not seem to have yet attracted the attention of many plant breeders. On the other side, in every cropping system, for every species, best performing cultivars are needed in each macro-ecology. Considering dif-ferent cropping systems, such as open or glasshouse production, main or second crop alternatives, plant breeders have to focus on the genotype-environment and genotype-input interactions.   Organic farming is in need of tailor-made genotypes for almost every crop. In fact, in the near future the same amount of organic registered cultivars will be needed as the conventional cultivars.  Conducting an immediate single or combined “seed-bed – pot – field test” might be a logical start to de-termine organic...

RoCo 2011-2013: Rødder og kompost, økologisk dyrkning med begrænset tilgængelighed af næringsstoffer
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian.
Folder med beskrivelse af RoCo projektet. De vigtigste emner i projektet er 1) undersøgelse af sortsvariation i rodvækst og næringsstofudnyttelse i sorter af vårhvede, salat og løg, 2) udvikling af komposttyper på basis af byaffald, 3) test og demonstration af kompost og hvedesorter, 4) udvikling af bagemetoder der tillader bagning med mel med lavere proteininghold og 5) undersøgelse af holdninger og barierrer for recirkulering af byaffaldskilder som gødning til økologisk jordbrug.

Combining agronomic and breeding approaches for improved nutrient use efficiency
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian.
There is a strong need to improve agricultural nutrient use efficiency (NUE), but NUE is complex, and not even well defined. The abstract and presentation deal with how NUE is determined by the combination of Genetic, Environmental and Management factors (GxExM), and how genetics as well as crop management must be combined in order to achieve improved overall NUE.

Breeding for nitrogen use efficiency in organic wheat systems
Provedor de dados: 21
Autores: Dawson, J.C.; Murphy, K.M.; Jones, S.S.
Improving crop nitrogen use efficiency (NUE) is important to reducing the environmental impacts of agriculture, for both perennial and annual crops. This study tested winter wheat breeding lines developed in organic and conventional systems, historic wheat varieties and perennial wheat under organic management.  There were significant differences among selection categories and among genotypes. However, standard methods of measuring NUE may not be appropriate when the breeding objectives are to reduce N use.  Alternative methods of evaluating breeding materials, including regression analysis of grain protein deviation (GPD) and principal component analysis (PCA) were explored.  GPD was not found to discriminate well between genotypes in this study, but PCA...

Organic quality wheat production - Results of long-term field trials of cultivation and selection of varieties
Provedor de dados: 21
Autores: Fischl, Martin; Traudtner, Franz; Surböck, Andreas; Kranzler, Andreas.
The leaflet addresses organic arable farmers. The first article is about quality parameters of organic quality weed, followed by a description of plant yield. Afterwards some seed-diseases are mentioned. Based on field trials the nutrient supply of wheat stock by crop rotation is explained. With the data of the field trials also recommendations for variety selection and mixtures of varieties are given. Further subjects are effects of stocking density and organic fertilization.

Artsvalg og gødskning i vårsæd
Provedor de dados: 21
Autores: Rasmussen, Henrik.
I år er fire forskellige arter af vårsæd afprøvet under økologiske forhold i landsforsøg, hvor der samtidig afprøves forskellige gødskningsniveauer. Resultater fra to forsøgsserier med henholdsvis korn og kløvergræs som forfrugt ses i tabel 1 og 2.

Rodvækst og sorter til økologi
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian.
Den tidlige rodvækst er vigtig for afgrødernes etablering i en økologisk dyrket jord med begrænset næringsstoftilgængelighed. Vi har studeret forskelle i tidlig rodvækst imellem sorter af vårhvede, og fundet betydelige forskelle både i samlet rodvækst, og i røddernes fordeling i jorden.

Produção de cebola orgânica em função do uso de cobertura morta e torta de mamona.
Provedor de dados: 21
Autores: Santos, Silvio da S; Espíndola, José Antonio A; Guerra, José Guilherme M; Leal, Marco Antonio de A; Ribeiro, Raul de LD.
A cebola é uma hortaliça consumida em grande quantidade e tem sua produção concentrada no âmbito da agricultura familiar, sendo responsável pela geração de emprego e renda para grande número de produtores rurais que tem no cultivo desta espécie sua única fonte de renda. É crescente a demanda por tecnologias para produção de cebola adequadas à agricultura familiar, com ênfase em técnicas agroecológicas. Neste aspecto, destaca-se a utilização de coberturas mortas e adubos orgânicos. O objetivo deste trabalho foi avaliar o efeito de diferentes coberturas mortas, associados a doses crescentes de torta de mamona aplicadas em cobertura, na produção total e no diâmetro dos bulbos de cebola produzidos em sistema orgânico. Observou-se efeito significativo da...

Ability of new durum wheat pure lines to meet yield stability and quality requirements in low input and organic systems
Provedor de dados: 21
Autores: Colomb, B.; Desclaux, D.; Debaeke, P.; Justes, E.; Burger, P.
Low-input production schemes adopted in organic or conventional farms require crop varieties that combine good product quality and high yield stability under non optimal environmental conditions (Gooding et al., 1999). These traits are not yet found among the durum wheat genotypes available in France. Consequently the cultivation of this crop is hardly successful in stockless organic farms in southern France, which are characterised by very low nitrogen resources. Some hopes emerged with the identification of new durum wheat pure lines with a high grain protein content in breeding experiments conducted near Montpellier in 2001 and 2002. The aim of the present work was to confirm and elucidate the origin of the enhanced protein performance of these new...
