The bread and durum wheat varieties grown in Southeastern Turkey are the main source of food consumed by the Turkish population and serve as bread and pasta. In this study, 12 kinds of durum wheat and 5 kinds of bread wheat samples registered by the International Agricultural Research and Training Centre of Turkey (IARTC, Turkey) were investigated for their multi-elemental concentrations (Ca, K, Mg, Fe, Zn, Mn, Si, Sn, Cu, Cr, Cd, Ni, V, Pb, As, and Se). The samples were microwavedigested and the elements determined by ICP-OES. The results were in good agreement with the certified values. This study shows that the elements Si, Fe, Zn, Cd, Cr, Cu, Sn, and Pb in durum wheat were higher than in bread wheat. Both wheat species were found to be rich in terms of Ca, Mg, and K. The multi-element content of some bread wheat and durum wheat was also in good agreement with the maximum allowable levels of the Food and Agriculture Organization (FAO) World Health (WHO).

This study investigated the effects of seed size and fertilizer usage with seed at planting on agronomic parameters of chickpea as a winter crop. The experiment was conducted according to split-split plots of randomized blocks with four replications. As factorial two chickpea varieties (Arda and Diyar 95), two fertilizer applications (with and without fertilizer) and three seed sizes (large, medium and small) are discussed in this study. The results showed that fertilizer applications along with seed at planting and large seed increased significantly the number of seed per plant, number of pods, biological yield, grain yield and 100-grain weight. However, fertilizer applications with large seeds had a negative effect on the output of the seeds and reduced grain yield per unit. In general, plants germinating from large seed had higher number of pods and number of seeds plant-1, 100 seed weight, biological and seed yield plant-1, while plants germinated from medium seed had higher emergence percentage, first pod hight, nodule fresh weight plant-1 and grain yield ha-1. These effects tend to decrease in chickpea varieties having medium-grain weight as Arda. It was concluded that, application of fertilizer along with seed during the sowing time results in decreased emergence percentage of the seeds and lower the yield in chickpea. © 2017, ALÖKI Kft., Budapest, Hungary.

The heat stress restricts the yield and quality parameters of durum wheat. The objective of this study was to examine some physiological and morphological parameters, which can be easily and quickly measured and resistance to heat stress in durum wheat breeding program. The study was conducted by using a total of 13 of durum wheat genotypes. Trials were conducted in irrigated conditions according to randomised complete blocks design with split plots and 3 replications as normal and late planting time. Drought stress was eliminated with irrigation and heat stress was formed with late planting time. According to heat susceptibility index (HSI), calculated over grain yield, Firat-93, Diyarbakir-81 and Sariçanak-98 varieties showed tolerant/medium tolerant. Low canopy temperature (CT), leaf erectness and waxiness were related with heat tolerance. Although SPAD readings did not relate heat tolerance, it can be used to select the genotypes which have high yield potential. Moreover, the GGE biplot indicated that PCA 1 and PCA 2 axes (principal component) were significant as P < 0.01 and supplied to 76.29% of the complete GT (Genotype × Trait) interaction. When the parameters were analysed for genotypes, four different groups were formed, in which grain filling speed (GFS) formed the first group, chlorophyll content (SPAD), waxiness (WXN), flag leaf steepness (FLS), grain yield (GY) formed the second group, canopy temperature depression (CTD) formed the third group and grain filing duration (GFD) formed in the fourth group. The traits, which located in same group, related to each other. On the other hand, GGE biplot showed that planting times took place in different mega-environments and some cultivars were related with normal planting time, while some others genotypes were related with late planting time. Statistical results indicated that GGE biplot are informative techniques to compare varieties with planting time and traits to discover general stability, adaptation pattern for practical recommendations.

This study was conducted to determine the relationships among seed yield and yield components, and their direct and indirect effects of contributing characters to seed yield in winter chickpea genotypes in 2011 and 2012 under Diyarbakır (GAP International Agricultural Research and Training Center) conditions. Five chickpea (Diyar 95, Arda, Yaşa 05, İnci and Aksu) cultivars were used in the study. The study was carried out in the Randomized Complete Block Design with four replications. The cultivars showed significant differences for all examined plant characteristics excluding number of primary branches and number of seeds pod-1 (p <0.01 and p <0.05). Highly significant and positive (p <0.01) correlations were found between grain yield with plant height, primary branches per plant, number of full pods per plant and seeds per plant, while 100-seed weight was negatively and significantly (p <0.05) correlated with seed yield. Path coefficient analysis results indicated that number of full pods per plant (1.048), plant height (0.352), seeds per plant (0.334) and seed per pod (0.332) were the major yield contributing characters due to their high direct and positive effects on grain yield. It was found that plant height and number of primary branches plant-1 had the highest indirect effect on grain yield via number of pod per plant. As a result, it was determined that plant height, number of pods plant-1, number of seeds pod-1 and number of seeds plant-1 can be good selection criteria for high grain yield in winter kabuli type chickpea breeding studies. © 2016, Centenary University.

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.

This study was conducted to evaluate the performance of forage pea (Pisum sativum spp. arvense L.) genotypes, in terms of fresh forage yield and associated traits, when grown on the Kiziltepe Plain, Mardin, Turkey. Field trials were performed during the 2007-08 and 2009-2010 growing seasons. The experiments were arranged according to randomized block design with three replications. The following trait ranges were reported: Days to 50% flowering: 147.5-162.5 days, Natural plant height and Main Stem Height: 45.58-72.75 cm, Main stem height: 52.52-100.42 cm, Main stem numbers per plant: 1.275-1.658 stems plant-1, Main stem thickness: 2.913-3.703 mm, Fresh forage yield: 10.43-23.83 t ha-1 and Dry matter yield: 2.525-5.891 t ha-1. GGE (i.e., G+GE) biplot analysis showed that the two growing seasons were markedly different, stemming exclusively from differences in rainfall amounts between the two growing seasons. Results of this study showed that the lines 88P00-1-4-9-661 (1) and P101 (6), and cultivar Kirazli (9) were superior in terms of fresh forage yield, dry matter yield, natural plant height and days to 50% flowering traits. At the same time, PC2 scores of these genotypes were found near to zero, so, they were identified as stable genotypes for the investigated traits. In conclusion, in terms of forage yield, these three forage pea genotypes are recommended for the Kiziltepe Plain growing conditions. © 2016, Tarbiat Modares University. All rights reserved.

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.


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.

The aim of study was to evaluate the yield performance of genotypes and stability, environments and G × E interaction of 12 spring barley genotypes in multi-environment trials. The trials were implemented in respect to a integrate arrangement complex style with four replications. The AMMI (Additive main effects and multiplicative interaction) analysis was made to estimate grain yield and understand G × E interaction patterns. Analysis indicated that the major contributions to treatment sum of squares were environments (81.4%), GE (10.3%) and genotypes (8.3%), respectively; suggesting that grain yield of genotypes was effected environmental conditions. PCA 1 and PCA 2 axes (Principal component) were significant (0.01) and supplied to 68.30% of the complete G × E interaction. The AMMI analysis revealed that E3 and E5 were more stable and high productive; mean while E6 and E7 were unstable and nominal efficient environments. According to stability variance, the genotypes (G1, G3, G6 and G9) were the productive and more stable; meanwhile G4 and G5 were low productive and stable genotypes. Moreover, G2 were the best productive to all environments without E2. The G × E model exposed according to AMMI analysis recommended that G2 shown candidates and registered as Kendal, because of wide adaptability with high performances in all environments.

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.
