The present study aims to compare three different types of designed flat-plate solar air heaters, two having fins (Type II and Type III) and the other without fins (Type I), one of the heater with a fin had single glass cover (Type III) and the others had double glass covers (Type I and Type II). The energy and exergy output rates of the solar air heaters were evaluated for various air flow rates (25, 50 and 100 m3/m2 h), tilt angle (0°, 15° and 30°) and temperature conditions versus time. Based on the energy and exergy output rates, heater with double glass covers and fins (Type II) is more effective and the difference between the input and output air temperature is higher than of the others. Besides, it is found that the circulation time of air inside the heater played a role more important than of the number of transparent sheet. Lower air flow rates should be preferred in the applications of which temperature differences is more important. © 2010 Elsevier Ltd. All rights reserved.

In recent days, healthy and reliable food has become one of the most important issues. Therefore, social-economic situation and status of agrochemical firms which are important information sources for farmers are examined. In this study, the data obtained from the owners of agrochemical markets in Isparta province were investigated by survey method. Data were evaluated to investigate the employer structure, obtaining selling inputs and credit usage of the firms. 56.2% of these firms were in company form and 6 of them were wholesaler. The agrochemical firms in Isparta region are small scaled newly established and individually owned firms. Most of them operate with their own capital. Agrochemical markets were positively affected by the latest regulations about opening the new agrochemical firms. It may be said that this tendency will be better in the future and agricultural agrochemical firms will employ agricultural engineers. Agrochemical firms are important organizations to inform farmers for new methods and development. Firms were found conscious on the agricultural chemical usage, but the cooperation between the firms and agricultural organization was found to be weak. Level of knowledge about EUROGAP among firm owners was also low. In order to improve the interaction level of firms with other institution and organization, seminar and panels should be organized. The consciousness level of agrochemical firms about production techniques like IPM and EUROGAP were not found to be high. Organizing training programs to increase awareness is important. Information level of farmers about diseases in the region has not developed as desired yet. In the same way, in order to increase the level of knowledge and awareness of farmers, the training programs should be increased to reduce unconscious chemical usage. As a result, one should not forget that any improvement in agricultural drug stores will have reflection on producers as well. © 2010 Academic Journals.

We report the effects of time of storage, temperature, and supplementation with sodium selenite- and selenium-enriched yeast on the quality of quail eggs. For this study, 90 10-week-old female Japanese quails (Coturnix coturnix japonica) with similar body size were caged individually and randomly divided into five groups of 18 quails each. One group was fed a normal diet and served as control. A second group was supplemented with 0.2 mg/kg sodium selenite (In-Se) and three groups supplemented with 0.1, 0.2, and 0.3 mg/kg of a commercially available selenium-enriched yeast (O-Se1, O-Se2, and O-Se3, respectively). The eggs were collected at third and fourth weeks of the experiment and were stored at 40C and 20°C for 0, 15, 30, and 45 days. Extension of the storage time to 45 days at 20°C resulted in significant deterioration of egg quality. The albumen Haugh unit (HU), pH, albumen index, yolk index, and egg weight loss were the most important parameters influenced by the nature of the selenium sources, storage time, and temperature. Storage time and temperature were also significant for egg weight loss, HU, and albumen and yolk indexes. The results show that supplementation with selenium yeast significantly affected shell weight, shell thickness, HU, albumen index, yolk index, and pH. The HU decreased with increased storage time and temperature. Higher levels of Se-yeast administration resulted in greater HU compared to the selenite and control groups. © 2010 Springer Science+Business Media, LLC.

Even though lentil has been an important food legume for centuries, genetic studies in lentil are still in their infancy. Genetic diversity and relationships among wild Lens species from Turkey has seldom been investigated. Additionally, a limited number of simple sequence repeat (SSR) markers have been developed for use in breeding and genetic studies of lentil crop. In this study, molecular characterization of 50 accessions mostly from Turkey, belonging to 6 wild and 1 cultivated Lens species, was performed using newly developed inter-primer binding site (iPBS) retrotransposons and inter-SSR (ISSR) markers. The 10 iPBS primers generated a total of 151 scorable bands, of which 150 were polymorphic (99.3%) with an average of 15.0 polymorphic fragments per primer. The 10 ISSR primers detected 138 scorable bands showing 100% polymorphism, with an average of 13.5 bands per primer. The average polymorphism information content (PIC) value for ISSR markers (0.97) was higher than that for iPBS markers (0.90). Lens orientalis was found to be the most diverse species, raising the possibility of wide crosses with cultivated species Lens culinaris. Cultivated varieties also showed high level of polymorphism, at 82.92% and 51.92% with ISSR and iPBS markers, respectively. Lens lamottei and Lens tomentosus were found as the least polymorphic species using both marker systems. The grouping of accessions and species within clusters were almost similar when iPBS and ISSR graphs were compared. Our data also suggested the role of iPBS-retrotransposons as '. a universal marker' for molecular characterization of wild and cultivated Lens species. © 2014 Elsevier Ltd.

We examined the physical, physicochemical, and cooking properties of 91 kabuli chickpea landraces from Turkey, using two cultivars (İnci and İzmir-92) as controls. All landraces were grown under the same agroclimatic conditions to eliminate variance caused by genotype × environment interactions. There was high diversity among the landraces in the contents of protein (17.55-23.31%), fat (4.45-6.11%), ash (2.54-3.41%), fiber (2.03-4.18%), starch (41.76-49.07%), moisture (6.39-10.57%), 100-seed weight (25.03-51.67 g), hydration capacity (0.2585-0.6169 g/ml), swelling index (0.7207-1.1859), swelling capacity (0.15-0.32 ml seed-1), cooking time (33-72 min), and seed density (0.8450-1.4800 g/ml). Regional analysis of landraces showed significant differences with respect to nutritional characteristics and cooking parameters. There were also significant relationships between various seed quality and cooking parameters. Together, our results provide an initial step toward identification of chickpea landraces that may be useful for development of high-quality chickpea cultivars. © 2010 Springer Science+Business Media B.V.
