Öğe A Research on the Problems, Tendencies and Social Structure of Students of Agricultural Faculties(Univ Namik Kemal, 2006) Demir, A.; Pala, A.; Baytekin, H.Social statues, tendencies and plans of students of agricultural faculties were investigated by a survey that had 21 multiple choice and 16 fill in the blanks questions. Only 10 out of 20 Faculties of Agriculture permitted the survey. The surveys were mailed to the universities and the completed 1845 survey forms were received by mail, between March 1st and May 15th, 2005. The data were analyzed using SAS V8.2 and odd ratios were calculated. According to the survey results, 64% of the students were from cities. 87% of the students stated that the education should emphasize the application more. This is because most of the students from cities are not exposed to agricultural practices. 72% of the students fear that they will be unemployed for a long time after graduation. The reason seems to be the excessive number of agriculture engineers and the negative public view on graduates of Faculty of Agriculture. Students who plan to work in private industry believed more in the benefits of education and followed the agricultural publications more closely compared to those who plan to work in a government office or to those who believe they will be unemployed for a long time (P< 0.01). Among the participants, only 6 % referred to agriculture as their ideal profession.Öğe Akdeniz kuşağı çalılı meralarında otsu türlerin mineral içeriklerinin değişimi(2013) Gökkuş, A.; Parlak, A. Ö.; Baytekin, H.; Hakyemez, B. H.Maki alanlarında çalıların sıklığına bağlı olarak önemli miktarda otsu tür kuru madde üretimine katkı sağlamaktadır. Bu yüzden bu çalışmada böyle meralardaki otsu türlerin mineral kapsamlarının yıl boyunca değişimleri ve bunun keçilerin beslenmesi açısından önemi araştırılmıştır. Deneme Çanakkale'nin korunan ve otlanan olmak üzere iki çalılı merasında kurulmuş ve 14 ay süreyle (Ekim 2006-Kasım 2007) yürütülmüştür. Bu maksatla her ayın ortasında 0,5 m x 0,5 m ebatlarında onar çerçeve biçilerek bitki örnekleri alınmıştır. Alınan örneklerde makro (N, P, K, Ca, Mg, S) ve mikro (Fe, Mn, Cu, B, Na, Zn) besin elementleri ile diğer elementlerden (Se, Co, Ni, Cr, Cd, Pb) oluşan toplam 18 elementin değişimi incelenmiştir. Araştırma sonucunda Se dışındaki bütün elementlerin hem korunan hem de otlanan mera otundaki değişimleri önemli olmuştur. Genel olarak bitkilerdeki N, K, Mg ve S oranları Nisan ayından itibaren yükselmiş, yaz, sonbahar ve kışın azalmıştır. P korunan merada yaz başında, otlanan merada ise ilkbaharda artarken, Ca'da tersi durum görülmüştür. Fe kışın yüksek, yazın düşük; Mn ve Cu kış ve ilkbahar aylarında nispeten yüksek, yazın çok düşük; B ve Na ilkbahar ve yazın fazla, sonbahar ve kış aylarında az; Zn kışın yüksek, diğer aylarda düşük olmuştur. Co, Ni, Cd ve Pb özellikle kış aylarında yüksek, yaz aylarında daha düşük; Cr ise Şubat ayında fazla öteki aylarda daha az bulunmuştur. Se genellikle ilkbaharda yükselmiştir. Meraların ortalaması olarak otun bünyesindeki N, P, K, Ca, Mg ve S miktarları sırasıyla 12,45, 1,98, 10,78, 10,36, 2,07 ve 1,45 g/kg; Fe, Mn, Cu, B, Na ve Zn miktarları ise 676,2, 143,0, 6,3, 23,4, 1497,5 ve 27,3 mg/kg olmuştur. Günde 1 kg kuru ot tüketen keçiler esas alınarak yapılan değerlendirmede; N'un yaz ve sonbahar başında, K'un otlanan merada yaz ve sonbaharda, Mn'ın yazın, S, Cu ve Zn'nun yıl boyu yetersiz olduğu, diğer besin elementlerinde ise eksiklik olmadığı belirlenmiştir.Öğe Bazı%Ekmeklik%Buğday%Genotiplerinde%Gliadin%Bant%Değişimlerine%Göre%Verim% ve%Kalite%Özelliklerinin%Biplot%Analizi%ile%Değerlendirilmesi(2014) Baytekin, H.; Egesel, C. Ö.; Kahrıman, F.; Aktar, M.; Tuncel, N. B.Bu araştırma, yurtiçi ve yurtdışı kökenli 40farklı ekmeklik buğday (Triticum) aestivum L.) genotipini Çanakkale koşullarında bitkisel özellikler, verim, un ve kalite özellikleri ile gliadin bant değişimleri bakımından karşılaştırılmak amacıyla yapılmıştır. Tarla denemesi 2008S2009 ve 2009S2010 yetiştirme mevsimlerinde, Çanakkale Onsekiz Mart Üniversitesi, Ziraat Fakültesi, Dardanos Araştırma ve Uygulama Birimi'nde yürütülmüştür. Genotiplerin incelenen özellikler bakımından gliadin bant değişimleri dikkate alınarak karşılaştırılması için, biplot analizinden yararlanılmıştır. Gliadin bant analizi sonuçlarına göre, genotipler 7 grupta toplanmış ve her grupta dikkate değer bir değişimin olduğu belirlenmiştir. Islah orijini yakın veya benzer coğrafyalardaki genotiplerin gliadin bant dizileri benzerlik göstermiştir. Biplot analizlerinde gliadin gruplandırmasına göre bazı genotiplerin hem bitkisel hem de kalite özellikleri bakımından birbirlerine benzerlik gösterdiği saptanmış ancak bu bakımdan denemeye alınan tüm genotiplerde kesin ve net bir ayrım yapılamamıştır. Yörede yaygın olarak yetiştirilen Sagittario'nun yüksek verimli ve kaliteli bir çeşit olduğu; diğer hakim çeşitler olan GönenS98 ve KaşifbeyS95'den denemenin yürütüldüğü yıl şartlarında verim ve kalite bakımından Selimiye, ZajecarskaS75, Guadelupe gibi daha üstün genotiplerin var olduğu tespit edilmiştir.Öğe Change of Mineral Composition of Herbaceous Species at the Mediterranean Shrublands(Univ Namik Kemal, 2013) Gokkus, A.; Parlak, A. O.; Baytekin, H.; Hakyemez, B. H.A significant amount of herbaceous species provide to be an increasing of total organic matter depending on shrub intensity in the maquis vegetation. Therefore, the yearlong mineral contents of these herbaceous species and their importance in terms of goat feeding were investigated at this vegetation. The trial was performed in two different sites, including protected and grazed, for a period of 14 months in canakkale (October 2006 and November 2007), and therefore the plant samples were collected by mowing the dimensions of 0.5 m x 0.5 m ten frames in the middle of each month. The change of total 18 elements, including macro (N, P, K, Ca, Mg, S), micro (Fe, Mn, Cu, B, Na, Zn), and other elements (Se, Co, Ni, Cr, Cd, Pb), was investigated in the collected samples. According to the results of the study, the change of all elements except for Se was significant in both protected and grazed areas. In general, N, K, Mg, and S ratios of the plants increased from April, and they decreased in summer, autumn, and winter. P from the protected area at the beginning of the summer and from the grazed area in the spring increased. The change of Ca followed an opposite path. Iron rates were high in the winter and low in the summer; Mn and Cu were relatively high in the spring and very low in the summer; B and Na were excess in the spring and summer and few in the autumn and winter; Zn was high in the winter and low in the other months; Co, Ni, Cd, and Pb were high especially in the winter and lower in the summer; Cr was high in February and low in the other months. Se increased especially in spring. As the means of both areas, N, P, K, Ca, Mg, and S amounts of the plants were 12.45, 1.98, 10.78, 10.36, 2.07, and 1.45 g/kg, respectively, whereas Fe, Mn, Cu, B, Na, and Zn amounts were 676.2, 143.0, 6.3, 23.4, 1497.5 and 27.3 mg/kg, respectively. In evaluation based on the goats which were fed with 1 kg hay per day, N in early summer and autumn, K from the grazed area in the summer and autumn, Mn in the summer and 5, Cu, and Zn throughout the year were determined as insufficient, whereas there was not found any shortage for the other nutrients.Öğe Forage quality of deciduous woody and herbaceous species throughout a year in Mediterranean Shrublands of Western Turkey(2011) Parlak, A.O.; Gokkus, A.; Hakyemez, B.H.; Baytekin, H.Nutritional stress during dry summer period is considered as a primary factor limiting goat production in the Mediterranean region. In this study, forage quality of two deciduous woody species (gall oak (Quercus infectoria Oliv.) and Christ's thorn (Paliurus spina-cristi Mill.)) and herbaceous species in a shrubland in the South Marmara was determined to assess their quality and capacity to meet goats needs. Dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), dry matter digestibility (DMD), metabolic energy (ME), Phosphorus (P) and Calcium (Ca) were determined in the shrubs and herbaceous. Results showed that DM and Ca in the gall oak were distinctly low in April. On the other hand, its CP and P were high in April while DMD and ME were high in May and June. Contents of DM, ash and Ca in the Christ's thorn showed a decrease in April-May and those of CP, DMD, and ME increased in May. Herbaceous had their lowest DM, NDF, and ADF in April and highest CP, DMD, and ME in March-April. Consequently, when goats' needs were considered, goats should be fed with supplementary energy feed throughout the year except for spring months, and with CP during autumn months in order to obtain satisfactory productivity.Öğe FORAGE QUALITY OF DECIDUOUS WOODY AND HERBACEOUS SPECIES THROUGHOUT A YEAR IN MEDITERRANEAN SHRUBLANDS OF WESTERN TURKEY(Pakistan Agricultural Scientists Forum, 2011) Parlak, A.

Genotypes Based on Gliadin Band Variations using Biplot Analysis(Univ Namik Kemal, 2014) Baytekin, H.; Egesel, C. O.; Kahriman, F.; Aktar, M.; Tuncel, N. B.This study was carried out to investigate and compare 40 wheat bread genotypes with different origins for their agronomic traits, grain yield, flour quality traits, and gliadin band variations. The field trial was conducted in 20082009 and 2009-2010 growing seasons at the Dardanos Research and Application Center of canakkaie Onsekiz Mart University, in canakkaie, Turkey. A new statistical method, calibrated biplot analysis, was used to compare the genotypes for the investigated traits, based on their gliadin band variation. Gliadin band analysis resulted in 7 different genotype groups, and significant variations were detected within each group. The genotypes originated in proximate or similar regions were found to be genetically close as suggested by the gliadin band analysis. Biplot analysis detected that some genotypes had similarities in terms of agronomic and quality traits within their respective gliadin band groups, whereas it was not quite possible to make a clear distinction for all of the genotypes. Overall results suggested that Sagittario, one of the prevalent varieties of the region, could be recommended to growers as a high yielding and high quality cultivar; while the other widely grown cultivars (i.e., Gonen-98 and Kasifbey-95) were inferior to some other genotypes (Selimiye, Zajecarska-75, Guadelupe) in terms of yield and quality, under the conditions of experimental years.Öğe The effect of harvest stage on the potential nutritive value of kermes oak (Quercus coccifera) leaves(2010) Ataşo?lu, C.; Şahin, S.; Canbolat, Ö.; Baytekin, H.The aim of the current study was to determine the effect of harvesting stage on the potential nutritive value of oak leaves using the chemical composition and in vitro gas production technique. The oak leaves were harvested in May, July, September and October of 2006 and analysed for their chemical composition. Gas production was recorded before incubation (0) and 3, 6, 12, 24, 48, 72 and 96 h after incubation. The harvest stage had a significant effect on chemical composition and in vitro gas production and the kinetics. The crude protein (CP) and ether extract (EE) content did not differ among the harvest stages (P>0.05). In contrast, the NDF, ADF and ADL contents increased (P<0.01) as the vegetation progressed. The condensed tannin content fluctuated (P<0.001) throughout the study. Generally the gas production of the oak leaves obtained in September and October was higher than those obtained in May and July. The rate of gas production, metabolisable energy (ME) and organic matter digestibility (OMD) values were also highest in October followed by in September, July and May. In conclusion, harvest stage influences the nutritional quality of kermes oak leaves with most of the nutritional parameters determined here being higher in autumn than in summer and spring.
