    Determination of yield and quality characteristics of local alfalfa genotypes cultivated in semi-arid conditions of Turkiye
    (Akdeniz Univ, Fac Agriculture, 2025) Seydosoglu, Seyithan; Cacan, Erdal; Kokten, Kagan
    Alfalfa is a field crop that can produce more protein per hectare than many other field crops. In order to be successful in alfalfa cultivation, varieties that are resistant to winter conditions, diseases and pests and have high yield characteristics should be preferred. In this study, seeds of six local genotypes were collected from farmers cultivating alfalfa in the Mus province of the semi-arid Eastern Anatolia Region. The field trial of this study, in which six local genotypes were compared with four registered varieties, was established in Bingol province in 2016 with three replications according to the coincidence blocks experimental design. In the study, some yield (green forage and dry matter yields) and quality traits (crude protein ratio, crude protein yield, ADF, NDF, digestible dry matter and relative feed value) of ten genotypes were analyzed for three years (2016, 2017 and 2018). As a result of the research, 68.57 t ha(-1) green forage yield, 24.07 t ha(-1) dry matter yield, 23.1% crude protein rate, 5.50 t ha(-1) crude protein yield, 24.3% ADF rate, 39.0% NDF rate, 70.0% digestible dry matter rate and 172.2 relative feed value were obtained from the genotypes. Sungu-3 and Varto genotypes, together with the registered varieties Elci, Nimet, Verko and Omerbey, gave the highest green forage yield, dry matter yield and crude protein yield. While there was no statistically significant difference between the genotypes in terms of crude protein ratio, it was observed that the registered varieties gave better results in terms of ADF, NDF and digestible dry matter ratios and relative feed value. It is foreseen that Sungu-3 and Varto varieties can be preferred and can be used as starting material in the breeding programs to be carried out since they give results close to the registered varieties in terms of yield characteristics.

    Determining the performance of alfalfa population collected from a narrow agroeceological zone of Turkey
    (Univ Federal Santa Maria, 2020) Cacan, Erdal; Kokten, Kagan; Seydosoglu, Seyithan
    This study was carried out to determine the yield and quality characteristics of some alfalfa village populations cultivated by producers in Bingol province of Turkey. Alfalfa seeds were obtained from 23 different locations in 2015. A three replicated, randomised complete block designed field trial was established in 2016 including these genotypes and four registered varieties. As a result of three year trials, it was determined that the populations obtained from the villages of Servi, Mutluca, Garip, Saricicek-1 and Bagliisa produced highest green herbage and hay yields. When we compare the quality results, Kumgecit, Kucuktekoren and Senkoy-1 populations stands out in terms of crude protein ratio. Highest crude protein yield was obtained from Servi population. In terms of relative feed value, it was observed that the varieties were better qualfied than the populations. It is concluded that the populations of Servi, Mutluca, Garip, Saricicek-1 and Bagliisa can be used in breeding studies especially to obtain genetic progress in yield of alfalfa for feed and bioenergy production. For the genetic improvement of current genotypes with higher crude protein ratio, Kumgecit, Kucuktekoren and Senkoy-1 populations can be used as a source. This study showed that, East Anatolia region is not just live-conserving highly diversified species but also covering special intra-species genetic diversity in microclimatic zones of Turkey to be used to improve the global forage and bioenergy cropproduction.

    Fatty acid content and nutritional composition of seeds of certain Triticale varieties
    (Innovhub Ssi-Area Ssog, 2025) Ozdemir, Selim; Seydosoglu, Seyithan; Kokten, Kagan; Cil, Abdullah
    Triticale cultivars can be grown for fodder as well as grain. Growing demand for food resources has led to an increased interest in triticale development. This cereal is receiving great attention as an alternative source of nutrients and health-protective components in the human diet. In this study, the lipid content and fatty acid composition of 7 triticale varieties were determined. The lipid content of the examined triticale varieties varied between 0.11 and 1.14%. The major unsaturated fatty acids found in the grain lipids of triticale varieties were oleic (17.16-22.74%), linoleic (53.67-57.84%) and linolenic (4.04-5.01%) acids. Levels of palmitoleic, arachidic, erucic, docosahexaenoic and nervonic acids were found to be lower than 1%. The crude ash (CA) and crude protein (CP) ratios in the grains of triticale varieties varied between 0.75-2.24% and 7.45-9.34%, respectively. The acid detergent fiber (ADF), neutral detergent fibre (NDF) and acid detergent lignin (ADL) ratios of the grains of triticale varieties varied between 7.91-9.04%, 25.34-29.45% and 1.06-2.96%, respectively. The dry matter digestibility (DMD) and dry matter intake (DMI) ratios and relative feed value (RFV) values of triticale grains varied between 81.86-82.74%, 4.08-4.74% and 260.74-302.54, respectively. The Presto, Umranhanim and Alperbey varieties have greater ADL and NDF properties; Aysehanim and Mehmetbey varieties had better ADF and CP ratios; the Tatlicak-97 variety recorded higher total digestible nutrients (TDN), DMD, digestible energy (DE) and metabolic energy (ME) values; the Tacettinbey variety had higher ash content, DMI and relative feed value (RFV).

    Fatty Acids Contents & Nutritional Compositions of Grains of Different Barley Genotypes
    (Innovhub Ssi-Area Ssog, 2025) Ozdemir, Selim; Seydosoglu, Seyithan; Kokten, Kagan; Cil, Abdullah; Turan, Nizamettin
    Barley is an important cereal in the world regarding its utilisation and extensive production as a feed and food grain in many countries. But little information is available on barley oil in terms of its composition. The aim of this study was to describe the importance of barley seeds by extracting their oil and determine its composition regarding lipids along with evaluations on composition, nutrient content, feed value and quality parameters. The crude ash, crude protein, ADF, NDF and ADL ratios of the seeds of barley genotypes varied between 3.5-7.1%; 8.3-13.4%; 13.5-26.0%; 23.8-36.3% and 1.99-8.78%, respectively. The DMD ratios, DMI ratios, RFV values, TDN ratios, DE and ME values of genotypes varied between 68.7-78.4%; 3.30-5.05%; 175.9-304.0%; 62.9-72.3%; 3.21-3.63 MJ/kg and 9.67-11.33 Mcal/kg, respectively. The total lipid content of the examined genotypes varied between 1.7 and 3.9%. Several fatty acids were detected; Palmitic, stearic and arachidic acids from saturated fatty acids were detected in the seeds of all barley genotypes examined in the study. The seed lipids of some barley genotypes contain palmitic (16.80-25.56%) and stearic (1.33-3.70%) acids as the major component of fatty acids, among the saturated acids, with small amounts of arachidic (0.24-0.54%) and behenic (0.06-0.90%) acids. The major unsaturated fatty acids found in the seed lipids were oleic (15.30-33.78%), linoleic (41.92-55.28%) and linolenic (2.84-5.43%) acids. Palmitoleic, erucic, docosahexaenoic and nervonic acids were shown to be lower than 1%. Eicosenoic and erucic acids were detected in all barley genotypes. Barley seeds may be used as a source of edible oil due to the presence of several unsaturated and essential fatty acids.

    GENETIC VARIABILITY FOR SEED NUTRITIONAL COMPOSITION IN PEARL MILLET GENOTYPES ANALYZED BY BIPLOT METHOD
    (Univ Quindio, 2023) Seydosoglu, Seyithan; Kokten, Kagan; Cil, Abdullah; Turan, Nizamettin
    This study evaluated the chemical composition of pearl millet seeds belonging to different genotypes by biplot analysis. Seeds of 26 different pearl millet populations obtained from ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) within the scope of TuBITAK 219O103 run by Sirnak University were used. The seeds were ground and analyzed for their chemical composition, i.e., acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP), digestible dry matter (DDM) and dry matter intake (DMI) rate. The results revealed that crude protein ratio varied between 11.74-19.24%, whereas ADF ratio differed between 3.44-11.43%. Similarly, NDF ratio varied between 10.23-23.47%, while DDM ratio ranged between 79.98-86.21%. Likewise, DMI ratio differed between 5.11-11.72%. Scatter plot obtained after biplot analysis indicated three different groups based on the analyzed traits. The first group contained DDM and DMI, whereas the second group consisted of ADF and NDF. The protein ratio was in the third group. It was determined that ADF-NDF and DMI-DDM properties were negatively correlated with each other. According to biplot, genotypes 'A5-13', 'A13-6' and 'B1-7' were prominent for ADF-NDF, DMI-DDM, and protein ratio, respectively. Therefore, these genotypes can be used in future studies to induce the desired traits.

    Status and health of some natural pastures in south east Anatolia region of Turkey
    (Range Management Soc India, 2019) Seydosoglu, Seyithan; Kokten, Kagan; Saruhan, Veysel; Sevilmis, Ugur
    To study the status and health of pastures in Derik district of Mardin province in south east Anatolia region, seven natural pastures were surveyed by modified wheel point with loop. Total of 45 plant species were recorded in studied pastures. The study was carried out during May and June 2015. Plant species were divided into three different groups: decreasers, increasers and invaders according to the palatability of the plant species for the grazing animals. Average vegetation cover ratio was found as 70.0%. Plant cover percentages of grasses, legumes and other family plants in the total plant cover were 21.53%, 29.19% and 49.28%, respectively. Invasive species were found dominant in these studied pastures. Thus pastures of Mardin province were highly degraded, and sustainable management and rehabilitation techniques need to be urgently applied to stop this on-going continuous degradation.
