The trial was conducted for 9 years on certified organic and conventional plots of Ege University, İzmir, Turkey. In both farming systems, pepper was the main summer crop, but the preceding crop varied between the farming systems and over the years. Certified organic seeds and seedlings of Yalova yağlık-28, an open pollinated variety, were used for Capia pepper production. Yields were statistically similar in the conventional (45,217 kg ha -1 ) and organic (43,645 kg ha -1 ) systems; however, significant yield variations occurred with respect to the annual conditions. The farming system significantly influenced fruit quality. The average fruit weight was 99.7 g in the conventional plots compared with 88.8 g in the organic. The fruit pericarp was thicker in the organic (5.1 mm) than in the conventionally grown ones (4.5 mm). The Lascorbic acid content was (73.4 mg 100 g -1 ) higher in the conventional fruit, whereas the total soluble solids (7.7%) and red pulp color, determined by a chromameter, as a*/b* (2.0), were more pronounced in fruit from the organic plots. The long-term trial showed that organic management helped to improve the soil organic matter content and fruit quality, especially from the perspective of processing. Keywords Capia pepper .

The present study compared the use of MeBr (60 g m -3 for 24 h) and alternatives-magnesium phosphide (1 and 2 g of phosphine (PH 3 ) per ton of dried fig for 5 days), and carbon dioxide (CO 2 ) at atmospheric pressure (in gas tight cubes for 5 days) and high pressure (2 h in pressurized tanks at 25 bars)-in controlling major pests (Ephestia cautella (Zell.) and Carpoglyphus lactis) of dried fig and in respect to dried fig quality. Fruit quality was investigated before exposure and after 2 months of storage at ambient conditions by analyzing moisture content, water activity, surface color, firmness, total soluble solids, titratable acidity, pH, and sugaring index. The effect on fruit surface was examined under a scanning electron microscope. The results show that the tested methods effectively controlled storage pests without any major adverse effects on quality, and each had an advantage for the implementation stage. Magnesium phosphide treatment of 1 g t -1 for 5 days is recommended due to its low investment and operational costs, CO 2 in pressurized tanks is recommended due to its short exposure period, and CO 2 under atmospheric pressure in gas-tight cubes is recommended due to its low cost and suitability for organic production.

Most of the produce is exported until Christmas. Ready-to-eat rehydrated figs are gaining importance as an alternative product and as a tool to add value to fruits with lower moisture content. The research work was carried out on 2000-2002 season fruits with the aim of optimizing pre-treatments for re-hydration of dried fig fruits. These pre-treatments comprised of variables as the duration, composition and temperature of the dipping solution, water vapor treatment and a mixed application of water vapour + hot water dipping. The fruit moisture content and water activity levels were determined for each variable. High moisture fig fruits were packed in gas-tight packages and quality changes were monitored during storage. The addition of potassium sorbate was tested to control microbial growth. The fruit moisture content distribution was more homogeneous in dipped fruits than vapour treated ones even if problems existed as the leaching of the soluble solids and the sticky nature of the final product. Among the tested variables, dipping in hot water at 90°C 10 min. or water vapour treatment at 100°C for 30 min. are recommended.

This research was conducted to determine the natural occurrence of fumonisin B(1) (FB(1)) and B(2) (FB(2)) on dried fig fruits of Sarilop (syn. Calimyrna) variety which are mainly grown in the Big and Small Meander Basins in the Aegean region, representing 60% of world dried fig production. A total of 262 samples belonging to two quality classes, Class A and Class cull, were collected from 12 different locations during the two crop years in 2004 and 2005. The fumonisin detection method is based on extraction with methanol-acetonitrile-water, derivatization with o-phthaldehyde and quantification by reversed-phase high-performance liquid chromatography with fluorescence detection. The mean concentrations of FB(1) and FB(2) in fumonisin-positive samples were 0.080 ± 0.047 µg g(-1) and 0.055 ± 0.031 µg g(-1) and ranged from LOD to 0.332 µg g(-1) and from LOD to 0.198 µg g(-1), respectively. The incidence of fumonisins significantly differed between the two crop years. This difference can be attributed to the alteration in the rainfall regime from mid-May to mid-August (7.2 mm in 2004, 90.9 mm in 2005) and number of humid wind currents from a westerly direction (183 in 2004, 492 in 2005) from the end of July and mid-August that may have triggered a higher incidence of Fusarium spp. and thus fumonisin production.

Quality parameters were determined as size, colour, acidity, soluble solids and ratio of defects, and were classified according to their relevance in fresh- and dried-fig production. The five top-ranking orchards were selected according to their overall quality. Soil properties and leaf nutrient status were also determined. Evaluations brought out the significance of nitrogen and potassium fertilization in commercial dried-fig production.

The myrtle plant, known as 'Hambeles', which has a white and large fruit had been cultivated in the region for many years. The black myrtle plant on the other hand, grows wild in forest characterized by smaller fruit sizes. Up to now, there has not been any registered black myrtle variety in our country. The results of the observations made in Antalya province showed the presence of some black myrtle ecotypes with large fruits. The aim of this study was to examine the characteristics of black myrtle types; fruit yield and shoot growth performance of this plant grown in two different ecologies of Antalya province. The myrtle plant has been cultivated in two different ecological areas, such as high and low lands. The cultured types were budded on the wild plants under high land conditions by using the patch budding method, whereas under low land conditions, the plants were grown by using own-rooted cuttings. The number of shoots emerged from the patches ranged from 3.9 to 7.0. The shoot length increased up to 208 cm in second growing season, but decreased to 104 cm in the third year. Fruit yield has increased markedly from the third year and reached up to 10.6 kg / plant.
