Methyl bromide (MeBr) is the common fumigant to control storage pests that infest during drying and storage. Compared with other dried fruits and nuts, storage pest infestation threatens dried fig production the most. MBr is regarded as a major anthropogenic compound that depletes the ozone layer. Furthermore, MeBr is a toxic gas and can pose risk to human health if over-exposure or accidents occur. The Montreal Protocol and the phase-out of methyl bromide have increased the urgency to search for new technologies. This project will lead to the phase-out of MBr as a stored product treatment in the Turkish dried fig sector by evaluating the economic and technical feasibility of two alternative technologies: 1) CO 2 at elevated temperatures and/or CO 2 in combination with pressure, and 2) magnesium phosphide in combination with heat in gas tight chambers. In addition, the project will include activities for ensuring a proper technology transfer, through a training programme and dissemination of information directed at actual MeBr users in the Turkish dried fig industry. Until today, field surveys are carried out to evaluate the importance of target species. Dried fig fruits are treated with magnesium phosphide and CO 2 at various concentrations and at different temperatures. Quality parameters such as total soluble solids (%), titratable acidity (%), pH, dry matter (%), water activity (WA), colour (L, a and b values by Minolta chromometer) and sugaring (%) are assessed in treated and non-treated samples.

Samples were obtained from five orchards located at 25, 74, 132, 202 and 250 m above sea level in Edremit (Balıkesir, Turkey). Olive samples were harvested at three maturity levels (green, semi-black and black) in 2007 and 2008 to extract the oil. E-2-hexenal was found to be the main volatile compound in all samples and its concentration decreased as maturity progressed. Hexanal and E-1-pentene-3-one were also at high levels in all samples. Levels of all aroma compounds, except E-2-hexenol and hexylacetate, decreased with the degree of ripeness. Altitude plays an evident but less intense effect on the volatile composition.

Meyve ve salça verimi ile briks gibi kalite özellikleri açısından organik ve konvansiyonel parseller arasında istatistiki anlamda önemli fark bulunmamıştır. Her iki uygulamada da ortalama 145 kg/parsel ve 8400 kg/da meyve verimi elde edilmiştir. Organik ve konvansiyonel parsellerden elde edilen % 5.0 briks değeri ile 1500 kg/da salça verimine ulaşıldığı belirlenmiştir. Buna karşılık verim değerleri bakımından deneme yılları arasında ise istatistiki olarak önemli farklılık tespit edilmiş, organik parselde geçiş yıllarında 9.0-9.8 ton/da olan meyve verim değeri organik sertifika sürecinin ilk yıllarında 7.6-8.0 ton/da, son organik yılında da 9.00 ton/da bulunmuştur.

If you consider agriculture, as cultivation or domestication of plants and animals then you may start evaluating the impact of mankind since the last 12,000 years. Today, still, agriculture provides food for all living organisms, and fibre and in some cases fuel for human beings. The World today nurture more than 7.2 billion as of April 2014 even if the ecological footprint has exceeded one. According to UN databases 1 , in 1980, out of 4.4 billion, rural population was 1.53 times more than the urban population. Those who were the producers were more than the consumers. In 2015, the rural/urban population ratio is estimated as 0.85 revealing that more will consume and less produce. If this ratio is dissected according to the regions of development: rural/urban population ratio is 0.27 in more developed regions, 1.05 in less developed and 2.30 in least developed regions of the World. Urban growth rate peaked (2.24 %) between 2000 and 2005. Rural growth rate that was 1.13 % between 1985 and 1990 is estimated to be 0.05 % between 2015 and 2020 and then at negative rates. By 2035, 61.7 % of the population will live in urban areas where as 38.3% in rural. So, less people in more and less developed regions of the world will try to supply food for more and more consumers or urban and peri-urban areas in developed regions will become more intensified for adequate agro-food production. Additionally, there are other major issues as changing life styles and consumption habits as higher calories and high consumption of animal products. Relationship between health especially of non-transmissible diseases and nutrition is a bottom-line for many, and new evidences strengthening these relationships appear through research as technology advances. Consumers in more developed regions of the world are becoming concerned about long-distance transfers of agricultural products, energy consuming distribution channels, loss of diversity, erosion of traditional foods or processing techniques. Agricultural land is threatened by intensification, urbanization, non-agricultural activities e.g. mass tourism, mining and climate change. How can agricultural production counteract these diverse issues and still be sustainable? Organic agriculture rooting on health, ecology, fairness and care principles as defined by IFOAM is practiced in 164 countries according to 2012 data 2. 88 countries possess a legislative framework for organic agriculture. How many have mutual recognition? Are there any derogations and why? The market size has reached to 63.8 billion US dollars. In all 164 countries data at least on production are collected. The product flows are still towards enlarging organic markets in more developed regions of the world e.g. US or Germany. Domestic markets are enlarging. Who consumes more organic and how much they spend? Why do the consumers prefer organic food/do they also prefer organic non-food products? Are they healthier? What are the health aspects? What are the quality attributes or is it the vital quality that makes it different than conventional systems? In which as

The Scientific track will contribute to bridging not only scientists but also institutions and disciplines, and to linking more developed and less developed, rural and urban, research to extension, plant to animal, farm practices to world-wide problems and producer and consumers. Organic is a management system that requires a diversity of inputs from different disciplines, therefore, an international Congress is the best medium to blend them. The Scientific Track is organized with special efforts of the co-organizers, International Society for Organic farming Research (ISOFAR; www.isofar.org) and EGE University (Turkey; www.ege.edu.tr). Organic e-prints (www.orgprints.org) acted as the hub for collection, revision and maintaining of all the papers. There were 568 manuscripts and abstracts received for the Scientific Track. Abstracts were not evaluated since the authors were obliged to submit full papers. About 96 reviewers - 37 from Turkey and 59 from all over the world (ISOFAR network) - contributed to the review process (double-blind: 1 reviewer international, 1 reviewer Turkish, final assessment and decision by the scientific board). At least, 300 papers have been accepted. They are from 51 countries and represent the countries, were 87 % of the global organic farm land and 75 % of the global organic farms are located. It is obvious, that organic farming is practiced world wide (but less the 1 % of the total farm land is managed organically), the organic markets are mainly in the western world (Europe, North America, Japan: 94 %) and the research is mainly done in Europe (publication share in web of science: 84 %, at the 4th ISOFAR congress: 69 %). [...] The papers are ordered by countries (country of the first author), not by sessions or disciplines. These decisions are made to make the proceedings affordable (all volumes can be purchased individually) and to merge and bridge the world and not split by disciplines and sessions. You find search facilities (indexes) to find all papers by discipline, eprint-number, keywords or sessions in each volume. A download of the full proceeding is possible under the webpage of ISOFAR (www.isofar.org) and as individual papers under organic eprints (www.orgprints.org). Due to the fact that all papers together comprise 1,300 pages, the printed Proceedings are split into four volumes. These proceedings comply all submitted, accepted for oral or poster presentation and revised manuscripts, but does not imply that they are all presented. The content of the papers are in responsibility of the authors and do not need to comply with the editors opinion.

The present experiments were designed to test the effects of carbon dioxide (CO 2) at atmospheric pressure (94 % CO 2 for 7 days in gas-tight cubes) and under high pressure (2, 3 and 5 h at 20 bars and 98% CO 2) on major storage pests (Ephestia cautella and Carpoglyphus lactis) of dried figs. CO 2 concentrations, temperature (o C) and relative humidity (%) values were monitored during treatments. Comparisons were made with control fruit treated with MB (60 g.m-3 for 24 h). Dried fig quality was assessed after the treatments and after 2.5 months of storage at ambient conditions. All tested CO 2 treatments controlled both of the tested pest species and had no negative effect on dried fig quality. Among tested treatments, high pressure application of CO 2 required high investment cost however was effective even at very short exposure periods as 2 h. CO 2 application in gas-tight cubes was recommended as a low-cost alternative despite its longer exposure requirement. CO 2 fumigation is allowed in organic certification systems and thus can be recommended for organic dried figs and other fruit and nuts that have a high demand in the organic market.

In most studies, representative samples of fruit lot are taken and analyzed to determine the average composition or quality. It is also well-known that variation exists among individual fruit even in the same tree. The study aimed to determine the variation in sugar composition of fig fruit (Ficus carica L. 'Sarılop') that occurs during drying. Fruits were collected at fresh, shrivelled (partially dried) and dried stages from two rain-fed orchards in Meşeli and Akmescit villages. In fresh fruit, peel and flesh were analyzed separately. Sugar fractions, glucose, fructose and sucrose were quantified by UHPLC using a refractive index detector. The results confirm that fructose and glucose are the major sugars in fig fruit. However, the analyses of individual fruits showed that glucose/fructose ratios vary between fresh and dried fruit. The peel of fresh fruits either has equal levels of both reducing sugars or slightly higher levels of glucose at concentrations around 6.0 g 100 g-1. Fruit flesh had a total of 11 to 15 g 100 g-1 of monosaccharides. Sucrose is detected only in some of fully dried fruits at concentrations of up to 3.23 g 100 g-1 DW. The presence of sucrose only in some individual dried fruit explains the contradictory results of previous researchers stating the presence or non-existence of glucose in fig fruit. © 2020 International Society for Horticultural Science.

Calimryna) that is located in Tire/Izmir the intensive fig-growing area in Turkey between 2001 and 2002. This study evaluates the soil properties, vegetative growth, leaf properties and fruit yield and quality characteristics as well as the water use efficiency calculated as photosynthesis/transpiration in fig trees grown as three farming systems (organic, biodynamic and conventional) to put forward the current and actual situation in fig production. The data were analyzed by using Minitab statistic program. At the end of the study, the questionnaires adapted to fig production indicated that many of the recommendation were adapted by the farmers. The obtained results showed that organic orchards have higher soil organic matter content and cation exchange capacity that effect leaf water use efficiency during the drought stress. There were no marked differences among the farm management systems in respect to analyzed fruit quality attributes.

The trial was performed with the Bursa Black, Goklop and Sarilop (syn = Calimyrna) varieties in Erbeyli-Aydin, the main fig-producing province of Turkey. The K, Ca and Mg analyses were carried out on whole intact fruits and on the skin, meat and pedicel of the fruit. It was found that in the Goklop and Sarilop varieties, there was a rapid decline in the Ca content of the fruit prior to ripening, as opposed to an increase in Bursa Black. Significant differences were determined among varieties with respect to fruit K, Ca and Mg content. The results are discussed in terms of fruit cracking.

Bugün büyük parsellerde üretilen meyve, sebze, kuru üzüm, çam fıstığı ve yonca ile 50 da alandaki mısır ve buğday ürünleri için "Organik Ürün Sertifikası" alınmıştır. Önümüzdeki yıllarda geçiş sürecinin tamamlanması ile 194 da alanda üretim yapılan buğday, fiğ+arpa ve mısır için "organik ürün sertifikası" alınabilecektir. Proje faaliyetlerinin başlaması ile birlikte günümüze kadar bitkisel üretim faaliyetleri açısından proje hedefine ulaşılmıştır. Projenin bundan sonraki ilk hedefi ise organik hayvancılık faaliyetlerine başlanmasıdır. Organik hayvan üretimi ile birlikte "organik süt ve süt ürünleri" ile "organik tarhana" üretimi de gelecekteki hedefler arasında yer almaktadır.
