  Determination of Grafting Success and Carbohydrate Distributions of Foxy Grape (Vitis labrusca L.) Varieties Grafted on Different American Grape Rootstocks

  Karabulut, Besim; Çelik, Hüseyin

  This study aimed to determine the grafting success and carbohydrate distributions for newly registered foxy grape varieties grafted on different American grapes and grown in humid conditions in the Black Sea Region of Turkey. In the study, ‘Rizessi’, ‘Çeliksu’, ‘Ülkemiz’, ‘Rizellim’, and ‘Rizpem’ foxy grape varieties were grafted on 140Ru, SO4, and 110R American rootstocks. The graft success, growth, and development characteristics were determined, and carbohydrate accumulations and distributions at the graft area, under the graft area (rootstock), and above the graft area (scion) of the grafted grapevines in the dormant period were also determined. The highest graft success rate was 100.00% in the combinations of ‘Rizessi’/SO4, ‘Rizellim’/SO4, ‘Rizpem’/SO4, ‘Rizellim’/110R, and ‘Rizpem’/110R. The percentage of vine saplings ranged from 86.00% (‘Rizellim’/SO4) to 27.14% (‘Rizpem’/140Ru). Regarding carbohydrate distribution, the ‘Rizessi’/140Ru, ‘Rizessi’/SO4, ‘Rizessi’/110R, ‘Çeliksu’/SO4, ‘Çeliksu’/110R, ‘Ülkemiz’/SO4, ‘Rizellim’/140Ru, ‘Rizellim’/SO4, ‘Rizpem’/SO4, and ‘Rizpem’/110R combinations showed a balanced distribution. The highest total carbohydrate accumulation (100.41 mg·L−1) was detected in the root region of the ‘Ülkemiz’/SO4 combination. On the other hand, vine sapling rate enhanced as carbohydrate accumulation increased in the grafting area. The SO4 American rootstock was found to be more successful than the others.

  Current Status of Forage Crops Cultivation and Strategies for the Future in Turkey: A Review

  Tan, Mustafa; Yolcu, Halil

  Forage crops cultivation area in Turkey is 2.312 million ha in 2020. The rate of forage cultivation in the total agricultural area is 6.1%, and its rate in the field land is 12.3%. Lucerne, silage corn, oat, vetch, and sainfoin are main forage crops in Turkey. The amount of produced is 16.8 million tons of hay and 48.8 thousand tons of seeds. The forage crop cultivation areas have increased by 206% since the beginning of the 2000s due to the government subsidies. However, shortage of quality roughage is still a big problem for animal husbandry of the country. For this reason, new strategies should be developed to increase forage cultivation areas by considering global warming, drought, and climate change. In order to meet the need for roughage, it is necessary to expand the cultivation area of forage crops as winter catch crops and second crops. In addition, some of the fallow fields should be utilized by growing drought-resistant forage species. The fields abandoned due to different problems should be used for the cultivation of suitable forage crops.

  Can Zeolite Application Decrease the Need for Nitrogen in Silage Corn?

  Gül, Zeynep; Tang, Mustafa; Yolcu, Halil

  The effects of applications of zeolite, nitrogen and zeolite + nitrogen on yield, quality and some morphological traits of silage corn was researched at the Research Station of the Agriculture Faculty, University of Ataturk, Eastern Turkey, during 2012 and 2013. Treatments included a control, three zeolite (Z(1): 500, Z(2): 1000, Z(3): 1500 kg ha(-1)), three nitrogen (N-1: 50, N-2: 100, N-3: 150 kg ha(-1)) and nine combinations of zeolite + nitrogen. The experimental design was randomized complete blocks with three replications. The application of zeolite + nitrogen application enhanced silage yield by 5.8-18.9%, dry matter yield by 4.5-21.4%, corncob rate by 6.6%, plant height by 3.0-16.1% and leaf rate by 17.5%. Further, the application of zeolite + medium or low nitrogen application produced similar silage yield, dry matter yield, dry matter rate, crude protein content, ADF, NDF, corncob rate, stem rate, plant height and leaf rate in comparison to the highest level nitrogen application. The results indicate that the application of zeolite + nitrogen can be used to increase efficiency of nitrogen and to decrease nitrogen requirements in silage corn for yield and other parameters.

  Karaalp, Musa; Aksakal, Vecihi; Sarikaya, Sevim Beyza Ozturk; Urusan, Hilal; Bayram, Bahri; Zulkadir, Ayhan

  The aim of this trial was to study the effects of consuming water with apple cider vinegar (ACV) and feed including mushroom (Agaricus bisporus) stalk (MS) on performance and certain egg characteristics. The hens were separated into four treatment groups (with 4 replicates and 6 hens per replicate). The experimental groups were control (not consumed ACV and MS), ACV (3 ml/l drinking water), MS (20 g/kg feed) and ACV+MS (combination). At the end of the experiment, among the performance criteria tested, body weight, feed intake, egg production and weight of eggs, and feed efficiency were not affected by the treatments (P>0.05). Treatments had no effect on physical external and internal egg characteristics. The amount of yolk malondialdehyde of the ACV and MS groups was lower than the control group (P<0.05) in stored eggs (28 d) (P<0.05).

  Higher PUFA and n-3 PUFA, conjugated linoleic acid, α-tocopherol and iron, but lower iodine and selenium concentrations in organic milk: a systematic literature review and meta- and redundancy analyses

  Srednicka-Tober, Dominika; Baranski, Marcin; Seal, Chris J.; Sanderson, Roy; Benbrook, Charles; Steinshamn, Havard; Gromadzka-Ostrowska, Joanna; Rembialkowska, Ewa; Skwarlo-Sonta, Krystyna; Eyre, Mick

  Demand for organic milk is partially driven by consumer perceptions that it is more nutritious. However, there is still considerable uncertainty over whether the use of organic production standards affects milk quality. Here we report results of meta-analyses based on 170 published studies comparing the nutrient content of organic and conventional bovine milk. There were no significant differences in total SFA and MUFA concentrations between organic and conventional milk. However, concentrations of total PUFA and n-3 PUFA were significantly higher in organic milk, by an estimated 7 (95% CI -1, 15)% and 56 (95% CI 38, 74) %, respectively. Concentrations of alpha-linolenic acid (ALA), very long-chain n-3 fatty acids (EPA + DPA + DHA) and conjugated linoleic acid were also significantly higher in organic milk, by an 69 (95% CI 53, 84) %, 57 (95% CI 27, 87)% and 41 ( 95% CI 14, 68) %, respectively. As there were no significant differences in total n-6 PUFA and linoleic acid (LA) concentrations, the n-6:n-3 and LA: ALA ratios were lower in organic milk, by an estimated 71 (95% CI -122, -20)% and 93 (95% CI -116, -70) %. It is concluded that organic bovine milk has a more desirable fatty acid composition than conventional milk. Meta-analyses also showed that organic milk has significantly higher alpha-tocopherol and Fe, but lower I and Se concentrations. Redundancy analysis of data from a large cross-European milk quality survey indicates that the higher grazing/conserved forage intakes in organic systems were the main reason for milk composition differences.

  Composition differences between organic and conventional meat: a systematic literature review and meta-analysis

  Srednicka-Tober, Dominika; Baranski, Marcin; Seal, Chris; Sanderson, Roy; Benbrook, Charles; Steinshamn, Havard; Gromadzka-Ostrowska, Joanna; Rembialkowska, Ewa; Skwarlo-Sonta, Krystyna; Eyre, Mick

  Demand for organic meat is partially driven by consumer perceptions that organic foods are more nutritious than non-organic foods. However, there have been no systematic reviews comparing specifically the nutrient content of organic and conventionally produced meat. In this study, we report results of a meta-analysis based on sixty-seven published studies comparing the composition of organic and non-organic meat products. For many nutritionally relevant compounds (e.g. minerals, antioxidants and most individual fatty acids (FA)), the evidence base was too weak for meaningful meta-analyses. However, significant differences in FA profiles were detected when data from all livestock species were pooled. Concentrations of SFA and MUFA were similar or slightly lower, respectively, in organic compared with conventional meat. Larger differences were detected for total PUFA and n-3 PUFA, which were an estimated 23 (95% CI 11, 35)% and 47 (95% CI 10, 84)% higher in organic meat, respectively. However, for these and many other composition parameters, for which meta-analyses found significant differences, heterogeneity was high, and this could be explained by differences between animal species/meat types. Evidence from controlled experimental studies indicates that the high grazing/forage-based diets prescribed under organic farming standards may be the main reason for differences in FA profiles. Further studies are required to enable meta-analyses for a wider range of parameters (e.g. antioxidant, vitamin and mineral concentrations) and to improve both precision and consistency of results for FA profiles for all species. Potential impacts of composition differences on human health are discussed.

  Nutritive Value of Sunflower Silages Ensiled with Corn or Alfalfa at Different Rate

  Tan, Mustafa; Yolcu, Halil; Dumlu Gul, Zeynep

  Sunflower (Helianthus annuus L.) having shorter growing season, better cold tolerant and more drought resistant is important alternative silage plant in highlands. But it has poor silage quality. To improve the quality of sunflower silage can be mixed an appropriate amount of corn (Zea mays L.) and alfalfa (Medicago sativa L.). This research was carried out to evaluate quality characteristics of nine silage types: Sunflower, corn and alfalfa silages; plus their some mixtures silages (75% sunflower + 25% corn, 50% sunflower + 50% corn, 25% sunflower + 75% corn, 75% sunflower + 25% alfalfa, 50% sunflower + 50% alfalfa and 25% sunflower + 75% alfalfa); at two harvest stages: Beginning of flowering for sunflower and alfalfa and milk-dough stage for corn (early stage), and end of flowering stage for sunflower and alfalfa, and dough stage for corn (late stage). The experimental design was in a factorial arrangement of randomized complete block with replicated four times. Dry matter content (DM), crude protein content (CP), neutral detergent fiber content (NDF), acid detergent fiber content (ADF), silage pH and physical characteristics (PC) of silages were determined in this study. Mixing of alfalfa in NDF, ADF and CP and corn in DM, pH and PC had positively effect in sunflower silages. Late stage had positively affected DM, PC and pH for silage. Consequently, sunflower silages mixed with corn, with the condition of not being less than 50% at late stage, are recommended for farmers.

  Yield, Quality, and Other Characteristics of Selected Lines of Crested Wheatgrass

  Gul, Zeynep Dumlu; Yolcu, Halil; Tan, Mustafa; Serin, Yunus; Gul, Ismail

  A field experiment was conducted to evaluate yield, quality, and other characteristics in selected lines of crested wheatgrass (Agropyron cristatum L. Gaertn.) at Ataturk University Agriculture Faculty Research Farm under unirrigated conditions during 2006, 2007, 2008, 2009, 2010, and 2011 in Eastern Turkey. The research was established in 2006 as a randomized complete block with three replications. Lines AC1 (Reg. No. PL-12, PI 667083), AC2 (Reg. No. PL-13, PI 667084), AC23 (Reg. No. PL-14, PI 667085), AC29 (Reg. No. PL-15, PI 667086), AC37 (Reg. No. PL-16, PI 667087), AC39 (Reg. No. PL-17, PI 667088), AC65 (Reg. No. PL-18, PI 667089), AC66 (Reg. No. PL-19, PI 667090), AC83 (Reg. No. PL-20, PI 667091), AC107 (Reg. No. PL-21, PI 667092), AC113 (Reg. No. PL-22, PI 667093), AC121 (Reg. No. PL-23, PI 667094), AC125 (Reg. No. PL-24, PI 667095) and Tohum Islah population (Reg. No. PL-11, PI 667082) (control) were evaluated for dry matter yield (DMY), seed yield (SY), straw yield (SWY), crude protein content (CPC), crude protein yield (CPY), stem number, plant height, and fertile tiller ratio. Forage DMY and SY increased over the first 4 yr, but the yields decreased due to the aging of the crested wheatgrass stand in the subsequent year. There were significant differences for lines in all variables, except for SWY and CPC. Particularly, lines AC1, AC23, AC29, AC37, AC39, AC65, AC66, AC107, and AC121 in DMY; AC1, AC37, AC83, AC107, AC113, AC121, and AC125 in SY; and AC23, AC39, and AC113 in CPY showed significant improvement compared with the original parent material. The results of DMY, SY, and CPY show that selection studies were effective. Selected lines will be useful for breeding studies and livestock production.
