| State of the Art: There is an increasing consumer demand for residue-free, thus organic table grapes from regional production. The cultivation of this fruit species, however, is delicate in humid climates and experience to advice growers still lacking. Definition of the problem: Developing and introducing a new culture of table grapes under Swiss climatic and economic conditions. Project aims: Study of the possibility to produce organic Table Grapes under Swiss climate and economical conditions Methodology: On farm trials, consumers taste test, variety testing and plant protection strategies in replicated field trials. Results, conclusion, state of the art: A quality organic production of Muscat Garnier and Muscat de la Birse has been established.... |

| TThree winter wheat composite cross (CC) populations were created in 2001 in the UK consisting either of 20 modern wheat parents (called A population), a subset of 12 high quality parents (Q), or a subset of 9 high yielding parents (Y). Seed of the F4 was transferred to the University of Kassel in 2005 and the populations were grown since then under organic and conventional conditions in well separated large (>100 m2) plots in two parallel sets (12 populations total) without conscious selection applied. In the conventional system fungicides and insecticides were not applied to expose the populations to natural pest and disease pressure. In addition, since the F8 two A populations have been maintained as broadcast sown populations without mechanical weed... |

| O presente trabalho teve como objetivo avaliar os teores de trigonelina, ácidos clorogênicos (5-ACQ) e cafeína em grãos de diferentes cultivares de cafeeiro (Coffea arabica L.). As cultivares avaliadas foram coletadas na Fazenda Experimental da Epamig em Lavras, Estado de Minas Gerais, no ano agrícola de 2005/2006. O delineamento experimental utilizado foi um inteiramente casualizado constando de oito cultivares de café com três repetições. Foram avaliadas as cultivares: Oeiras MG 6851, Acaiá Cerrado MG 1474, Catuaí Vermelho IAC 99, Rubi MG 1192, Topázio MG 1190, Mundo Novo IAC 379/19, Catucaí Amarelo 2 SL e Catuaí Amarelo IAC 62. Após a colheita dos cafés por derriça manual no pano, estes foram lavados e submetidos ao processo de descascamento e... |

| O objetivo deste trabalho foi averiguar o desempenho de vinte e nove cultivares de mandioca, quanto às variáveis altura da planta, rendimentos da parte aérea, de raízes tuberosas e de amido e teores de matéria seca e de amido nos municípios de Cruz das Almas/BA e Umbaúba/SE, inseridos em áreas de Tabuleiros Costeiros desses estados e, São Domingos/SE, localizado no Agreste sergipano, para fins de recomendação. Foram plantados dois ensaios na safra 2010-2011, utilizando-se o delineamento experimental em blocos ao acaso com três repetições dos 29 tratamentos. Esses ensaios foram colhidos aos 12 e 15 meses após o plantio. Detectaram-se, nas análises de variância conjuntas, diferenças entre as cultivares e os ambientes e inconsistência no comportamento das... |

| Com o advento da agricultura moderna, as sementes crioulas foram, em geral, substituídas por cultivares híbridos, com elevado potencial produtivo, porém mais dependentes de insumos e tecnologias intensivas. O objetivo deste trabalho foi avaliar variedades de milho crioulo, de forma a identificar materiais mais produtivos e que propiciem o processo sustentável no qual os próprios grãos possam ser utilizados como semente. Foram avaliadas 15 variedades de milho crioulo, tendo como testemunhas as cultivares comerciais BR 106 e IPR 114. Os experimentos foram conduzidos em Arapongas e Imbaú, Estado do Paraná, durante o ano agrícola de 2004/2005, sem a utilização de insumos externos. O delineamento utilizado foi o de blocos casualizados com quatro repetições. As... |

| ABSTRACT The present study aims to characterize the genetic diversity of Passiflora setacea, P. edulis, their hybrids, and first-backcross progenies, and to indicate promising recombinants for generation advancement in a breeding program for transferring resistance to cowpea aphid-borne mosaic virus (CABMV). Ninety-one genotypes were evaluated for 37 morphoagronomic descriptors. The traits were analyzed to obtain a distance matrix, based on the Gower algorithm, using the Ward-Modified Location Model (MLM) procedure for the composition of genetic groups. The adopted strategy led to the formation of five homogeneous groups, where groups I, III, and V comprised the parents P. setacea, P. edulis and interspecific hybrids, respectively, while groups II and IV... |

| The NAHMS Beef '97 Study was designed to provide both participants and the industry with information on the nation's cow-calf population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically-valid sample yielding 2,713 producers from 23 states. The 23-state target population represented 85.7 percent of U.S. beef cows on January 1, 1997, and 77.6 percent of U.S. beef operations. NASS enumerators collected data for this report via a questionnaire administered on-farm from December 30, 1996, through February 3, 1997. Contact for this paper: David Dargatz |

| The behaviour of ostrich chicks bred in captivity was studied by using groups with 30 birds in five age groups: from 10 to 40 days of age; from 41 to 60 days of age; from 61 to 90 days of age; from 91 to 120 days of age and from 121 to 150 days of age. Six birds at each age were ringed around one of their feet and observed for four consecutive days for eight hours daily in three periods (in the morning, at noon and in the afternoon), following the "one-zero" method for sampling. The order for observation of behaviour of the six selected birds was performed randomly at every thirty minutes, totalling 16 periods or 80 minutes/bird/day. Fourteen types of behaviour were observed. There were differences among ages for behaviour like standing, walking, running,... |

| Grundet et nyt EU-direktiv skal alle økologiske landmænd i EU fra 2001 udelukkende anvende økologisk fremavlede frø. Da Danmark er førende på området, og hvidkløver er den vigtigste afgrøde på de økologiske gårde, er der behov for at øge dyrkningen. Der er imidlertid en række dyrkningsmæssige faktorer, der tilsammen er årsag til meget lave udbytter i de økologiske frømarker. Denne opgave omhandler disse faktorer, med særlig vægt på at undersøge vækstregulering, bestøvning og angreb af hvidkløversnudebillens larvers betydning for frøudbyttet. Faktorerne er analyseret ved litteraturstudie, og desuden blev der udtaget hvidkløverhoveder fra et parcelforsøg opstillet ved SJF-Flakkebjerg. På baggrund af de hovedanalyser der blev foretaget, blev der... |
