This study was conducted to determine fresh forage yield, dry matter yield, and their affecting components in promising narbon vetch lines (Vicia narbonensis L.) under rainfed conditions in the Southeastern Anatolia region of Turkey. Field trials were performed in the research areas of GAP International Agricultural Research and Training Center (GAP IARTC) in Diyarbakir, Turkey during the 2008-09, 2009-10 and 2010-11 growing seasons with winter sowings. Experiments were established according to randomized blocks design with three replications. Although the genotype × year interaction for the natural plant height trait was not found to be significant, the interaction was statistically significant (P<0.05) for the main stem number trait. For the other five traits, including fresh forage and dry matter yields, the genotype × year interaction was highly statistically significant (P<0.01). Among growing seasons and genotypes the investigated traits had ranges as follows: fresh forage yield-19.42-37.95 t ha-1; dry matter yield-4.07-7.16 t ha-1; days to 50% flowering-142.3-171.0 days; natural plant height-63.8-79.3 cm; main stem height-79.3-133.3 cm; main stem numbers per plant-1.93-3.40 stems plant-1; and main stem thickness-33.2-4.97 mm. Correlation analyses indicated that there were highly significant and positive correlation between fresh forage yield and dry matter yield, though the correlation between fresh forage yield and days to 50% flowering were found as statistically significant and positive (P<0.05). According to averages over the three study years five promising narbon vetch lines: IFVN 564-Sel 2379, IFVN 565-Sel 2380, IFVN 567-Sel 2382, IFVN 116-Sel 2461, IFVN 562-Sel 2470, were all found more productive than the control cultivar, Tarman-2002, in terms of both fresh forage yield and dry matter yield. © Ankara Üniversitesi Ziraat Fakültesi.

This study was carried out to determine the effects of plant-growth-promoting rhizobacteria (PGPR) on cucumber (Cucumis sativus L. cv. Sardes F1) production in perlite under unheated greenhouse conditions. Four native bacterial strains (18/1K: Pseudomonas putida, 62: Serratia marcescens, 66/3: Bacillus spp., 70: Pseudomonas fluorescens) and one commercial product (FZB24: Bacillus amyloliquefaciens) were tested. Rhizobacteria inoculation took place before sowing and after transplanting. Plants were affected by Fusarium oxysporum f.sp. cucumerinum occurred naturally and effects of PGPR on cucumber yield were found statistically significant. Plants inoculated with Pseudomonas putida strain 18/1K and Serratia marcescens strain 62 gave significantly higher yield compared to the control plants. © 2013 Elsevier B.V. Source

The purpose of this study was to examine applied rangeland improvement and management studies carried out from 2004 to 2011 in six provinces of the Southeastern Anatolia Region of Turkey. The aims of the studies were to (1) protect and conserve rangeland soil and water resources, (2) improve and strengthen weakened rangeland vegetation, and (3) increase hay yields and grazing capacities of the rangelands. Additionally, one of the most important goals of these studies was to enhance the cultivation of forage crops in cultivated areas in order to decrease the adverse effects of overgrazing and to supply quality roughage for livestock. To achieve these objectives, different rangeland improvement methods and rangeland management strategies were applied in 40 different rangelands in the region. The results indicated that the average sufficien t rangeland area per animal unit was 1.99 ha, whereas the value recorded prior to these studies was 4.80 ha. © 2015, University of Agriculture.

The main aim of this study is to determine consumer behavior towards product quality and particularly towards local and non-local products labeled with geographical indications (GIs). In doing so, two GI products were identified, locally and non-locally produced, for the same market (IZMIR) and with the same consumer potentials for both products. In addition, consumer attitudes regarding these two products, a local product (South Aegean Olive Oil) and a non-local product (Ayvalik Olive Oil), were analyzed and then compared. Consumers' willingness to pay for both cases was estimated and the frequency of buying the products was measured utilizing 271 questionnaires. Factor analysis was run to show the main factors in accordance with consumers' behaviour. Afterwards, these factors were analyzed by using binary logistic regression to identify the factors influencing consumer characteristics and to study factor interactions. Results demonstrate that consumers behave reliably according to local GI-labeled products. Primarily, quality and origin of the products play significant roles in consumers' purchase decisions and consumers' reliance on local products is greater than non-local products. © 2014 Springer-Verlag Berlin Heidelberg.

A study was conducted to examine the effects of genotype × environment interaction (GEI) on grain yield, its components, and quality characteristics using genotype main effect (G) plus genotype × environment interaction (GE) (GGE) biplot analysis. Significant differences were observed among cultivars in grain yield, yield components, and quality traits and the relationship between yield components was used to identify three groups. Positive correlations were found between quality parameters and yield components, whereas correlations of quality parameters with yield and yield components were negative. The GGE biplot indicated that E6 (single irrigated location at Diyarbakir) was an ideal environment for all traits and E5 (rainfed locations at Diyarbakir) was a highly efficient model for quality parameters. The biplot analysis showed that Zenit was the best cultivar in terms of yield and quality and Zühre was efficient for quality parameters only and hence these two genotypes can be recommended to Southeastern Anatolia Region in Turkey. © 2015, Indian Society of Genetics and Plant Breeding.
