  • Evaluation of the Directly and Indirectly Effects of the
           Morpho-Physiological Traits of Sweet Corn Seedlings on Yield with
           Structural Equation Modeling Partial Least Square (SEM-PLS) Approach

    • Authors: Bhaskara Anggarda Gathot SUBRATA; Mehmet KİREMİT, Elif ÖZTÜRK, Hakan ARSLAN, İsmail SEZER, Hasan AKAY
      Abstract: Environmental stress factors have a very complex effect on the growth and growth parameters of plants. Therefore, special analytical techniques such as SEM-PLS can better understand the between observational variables and abiotic stress factors. Therefore, the present study was aimed to evaluate the, directly and indirectly, effects of the growth and biochemical parameters of sweet corn seed on yield, which seed primed with different melatonin doses and grown under different soil salinity conditions using the SEM-PLS model. Seeds of sweet corn cultivar Vega F1 were soaked in 0, 50, 100, and 200 μM of melatonin solution for 24 h, and then primed seeds were cultivated under four (0.27, 5.45, 9.00, and 12.32 dSm-1) soil salinity conditions. The study results showed that melatonin directly and positively affected growth parameters (β = 0.502, p <0.05). In contrast, salinity directly and negatively affected growth parameters (β = -0.689, p <0.05). Also, melatonin had a mostly indirect effect (β = 0.623) on biochemical components compared to direct effect (β = -0.277). The indirect effect (β = -0.855) of salinity on biochemical components was more significant than its direct effect (β = 0.244). Finally, the SEM-PLS can be used as a significant tool for understanding the benefits of melatonin and salinity’s positive or negative effects through direct and indirect relationships with the mediating variables of growth parameters and biochemical, which are essential to optimize sweet corn yield.

  • Breed Preferences and Reasons of Cattle Breeders in Turkey

    • Authors: Onur ŞAHİN; Ali KAYGISIZ, İsa YILMAZ
      Abstract: This study was carried out in order to determine the preferences and reasons of cattle breeds in line with the opinions of breeders. In the study, the number of questionnaires was determined as 487 people by simple random sampling method. Descriptive statistical values of each question category answered by the breeders were made using the SPSS 20.0 package program. As a result of the evaluations, In the breed preference of the breeders, 31.2% of the breeders took the first place with the Simmental breed. This breed was followed by Holstein Friesian (Black and White) breed with 27.9% and Brown Swiss breed with 14.8%. The rate of preference for other races was 26.1%. Among the effective reasons for breeders' breed preference, milk yield was the first (18.9%). The reason for this preference was followed by milk fat yield, progeny yield and sales ability (11.9%, 11.9% and 11.3%, respectively), which had equal preference rates. Carcass yield per animal was ranked 3rd (10.2%) in the list of reasons for breed preference. While 46.0% of the breeders prefer the breed they will breed; reported that toe-nail strength, easy care, resistance to mammary diseases, temperament, milk protein and sympathy for the race were effective. As a result, the priority in the race preference belongs to the Simmental breed, followed by the Holstein Friesian and Brown Swiss breeds. The most important reason for racial preference was high milk yield, followed by reproduction (offspring yield), ease of marketing and high milk fat ratio. It is estimated that climate change and drought due to increasing global warming will significantly affect the breed preference in the near future. For this reason, in order to obtain breeds with high temperature tolerance and resistant to blood parasitic diseases such as Theileriosis and Anaplasmosis, it is recommended to focus on crossing the culture breeds in Turkey with the Southern Anatolian Red breed, as well as supporting the crossing studies with genome-wide analysis method.

  • Early Breeding Possibilities of Akkeci Female Kids

    • Authors: Füsun COŞKUN; Mehmet ERTUĞRUL
      Abstract: The study aimed to determine the early breeding possibilities of Akkeci (Saanen x Kilis (B1)) female kids. Animal material of the trial was formed by; 21 female kids, 17 yearlings, and 24 2-5 years old does. Any special feeding program was not applied during the breeding season. In terms of the onset of estrus, there was no statistically significant difference between the kids, yearlings, and does. The number of mating per pregnancy was 1.13 in kids and 1.00 in yearlings and does. The number of kids born per goat giving birth (litter size: kids born goat kidding-1) was 1.13, 1.31, and 1.46 in kids, yearlings, and does, respectively; Kids born per goat mated (fecundity: kids born goat mated-1) was determined as 0.89, 1.23, and 1.46. The results showed that the difference between the mean gestation days of the kids, yearlings, and does groups is not statistically significant. The difference between the kids and yearlings groups in terms of pregnancy rate, kidding rate, twinning rate, and infertility rate was not statistically significant. Although there were statistically significant differences (P<0.01) between the mean live weights of groups at mating and at birth, there was no statistically significant difference between groups for the birth weights of their offspring and kid lost in the three days after birth. As a result of the study; it can be concluded that the early breeding of Akkeci female kids has not any significant disadvantage. On contrary, it contains economical and breeding advantages but it is needed that new studies to investigate the effect of early breeding on whole life productivity and breeding life.

  • Effects of Mycorrhizae and Salicylic Acid on Growth, Cadmium Content and
           Uptake of Maize (Zea mays L.) Seedlings in Cadmium Contaminated Media

    • Authors: Füsun GÜLSER; Ferit SÖNMEZ
      Abstract: Cadmium (Cd) pollution is an important problem today. In this study, the effects of mycorrhiza (M) and salicylic acid (SA) applications on plant height, fresh weight, dry weight, number of leaves, and Cd content and uptake of maize (Zea mays L.) seedlings grown in Cd treated environments were determined. For this purpose, 3 kg pots with and without mycorrhizae were used with two doses of salicylic acid (SA1: 1.0 mM and SA2: 2.0 mM). The study was carried out in three replications. As a result of the measurements, mycorrhiza and Salicylic acid applications significantly increased plant height, fresh and dry weight of corn seedlings. On the other hand, mycorrhiza and Salicylic acid applications decreased Cd content and uptake. The lowest plant height was 26.63 cm, the number of leaves was 5.6, the fresh weight was 3.74 g and the dry weight was 1.63 g in the control group, which was not treated with mycorrhiza and SA. The highest plant height was 56.17 cm, the number of leaves was 7.50, and the fresh weight was 21.46 g, with 2.0 mM SA application without mycorrhiza treatment. The highest dry weight was determined with 5.70 g in mycorrhiza and 2.0 mM SA application. While the highest Cd content of corn seedlings was 3.37 mg kg-1 and its uptake was 5.95 mg kg-1 in the control application, the lowest Cd content was 0.307 mg kg-1 and uptake were 1.48 mg kg-1 with mycorrhiza with 2.0 mM SA and 1.0 mM SA. detected in applications. When the results of our study were examined, mycorrhiza and SA applications had positive effects on corn seedlings grown in Cd-contaminated environments. The combined application of salicylic acid and mycorrhiza will contribute significantly to yield and nutrient content in agricultural production against heavy metal pollution.

      Abstract: This study aimed to determine the physical and chemical properties of Brown and Brown Forest Great Soil Groups soils where wheat is grown in Eskişehir province, Seyitgazi district, to reveal their productivity status and to solve potential nutritional problems. In this study, a total of 45 soil samples (9 different regions x 5 soil samples) were taken from 9 different regions at a depth of 0-20 cm. In soil samples; texture, pH, EC, lime (CaCO3), organic matter, N, P, K, Ca, Mg, Fe, Mn, Zn, Cu, and B were analyzed. According to the results of the research; Brown Great Soil Group soils were generally determined as sandy-clayey-loam, slightly alkaline, medium calcareous, medium amount of organic matter, low salinity, sufficient total N and available P, high changeable K, Ca, and Mg. Brown Forest Great Soil Group soils were generally determined as clayey, neutral- slightly alkaline pH, without salinity risk, low calcareous, well the amount of organic matter, sufficient total N and available P. Although the P amount in this soil group is higher than the other soil group, it has been determined that the exchangeable K, Ca and Mg contents are higher. The available Fe content is less in Brown Great Soil Group, the available Mn and Zn content in each large soil group were low and Cu was sufficient in each large soil group. Available B content was sufficient in Brown Great Soil Group, while available B content was low in Brown Forest Great Soil Group. In general, it is concluded that Brown Forest Great Soil Group had better soil properties than Brown Great Soil Group according to fertility parameters.

           Content in Soybean (Glycine max L.)

    • Authors: Abdurrahim YILMAZ; Hilal YILMAZ, Hakkı Ekrem SOYDEMİR, Vahdettin ÇİFTÇİ
      Abstract: Soybean (Glycine max L.) has an important potential in closing the oil deficit in our country, is a very valuable oil plant with its high protein and oil ratio. The fact that it contains fatty acids that regulate lipid metabolism of humans and linoleic fatty acid known as Omega-3 makes this plant prominent in human and animal nutrition. This study, which investigated the yield characteristics and protein content of soybean plants with AMF and PGPR applications, was carried out in Bolu Abant İzzet Baysal University Özbostancı Research and Experiment area in 2020. Plant height (cm), pod number (per plant-1), first pod height (cm), seed yield per plant (g plant-1), yield (kg da-1), and protein content (%) values were determined in the study was established with 3 replications according to the randomized blocks experimental design. It was observed that the applications provide superior values than the control in all yield parameters. It is noteworthy that the AMF application gives a statistically higher average value (433.0 kg da-1) than other applications, especially in yield per decare. In protein content, it was determined that PGPR+AMF combined application had the highest average value, but this result did not make a statistical difference with other applications. The information obtained from the results of the study will provide useful information to the entrepreneurs investigating the yield and protein content of the soybean plant.

  • The Effect of Different Sowing and Harvest Periods on Herbage Yield and
           Some Yield Components in Mountain Spinach as Alternative Forage Resource

    • Authors: Süleyman TEMEL; Bilal KESKİN
      Abstract: Determining of the suitable sowing and harvest periods of the plants according to regions is of great importance for a profitable and high yielding roughage production. However, there is no study on the Mountain spinach (Atriplex nitens Schkuhr) considered as alternative forage resource based on different sowing and growth periods in field conditions. With the present study, the effect of different sowing (mid-April, late-April, early-May, mid-May) and harvesting periods (end of vegetative period, beginning of flowering, full flowering period) on herbage yield and components was tried to be determined. For this purpose, a study was planned according to randomized complete block in split plots with three replications in Iğdır irrigated conditions in 2019 and 2020. The results showed that the years (except plant height, number of branches and crude protein yield), sowing times and harvest periods (except crude protein yield) had a significant effect on the parameters studied. As a result of the study, it was determined that the examined parameters increased as the harvest period was delayed and decreased as the sowing time was delayed (except leaf ratio). In addition, in the correlation analysis; It was determined that there was a very significant and positive relationship between all the examined variables (except leaf ratio) and dry herbage yield. As a result, it was concluded that sowing should be done at the first opportunity (mid-March) and harvesting should be done at the full flowering period for high fresh herbage (14503.0-16947.2 kg da-1), dry herbage (4489.1-4906.9 kg da-1) and crude protein yields (386.1-469.3 kg da-1).

    • Authors: Başak AYDIN; Erol ÖZKAN, Emel KAYALI, Volkan ATAV, Mehmet Ali GÜRBÜZ, İlker KURŞUN, İhsan Engin KAYHAN
      Abstract: The structural characteristics and the factors affecting the soil analysis decisions of the farmers in Edirne and Tekirdağ provinces were determined in this study. The factors affective on the soil analysis decisions of the farmers were analyzed by using logistic regression analysis and artificial neural networks and the comparison of the methods was done. In each province, 3 laboratories which had the most sample acceptance number for soil analysis were selected. The surveys were conducted with total of 60 farmers who referred to the laboratories and utilized from soil analysis subsidies and 40 farmers who did not utilize from soil analysis subsidies and had the similar characteristics with the farmers who utilized from soil analysis subsidies in each province and total of 200 farmers participated in the survey in 2019. The most significant factors on soil analysis decisions of the farmers were determined as total land size, age, agricultural experience, experience on taking soil sample, family size, education period and the activity type in each two methods. Total accurate classification ratio was found as 77% in logistic regression analysis and 80.67% in artificial neural network analysis. It was determined that the classification percentages obtained by two methods were pretty close to each other. The farmers who had low yield and low qualified crop due to not having soil analysis should be informed and necessary publication studies should be done.

  • Infestation and Damage Caused by Wheat Stem Sawfly, [Cephus pygmeus
           (Hymenoptera: Cephidae)], at Wheat Fields in Yozgat Province, Turkey

    • Authors: Hasan İNCE; Ramazan CANHİLAL, Çetin MUTLU
      Abstract: Cephus pygmeus L. (Hymenoptera: Cephidae), known as the European Wheat Stem Sawfly, is one of the most common pestobserved in wheat fields in our country.. This study was carried out to determine the larvae infestation rates of C. pygmeus, the damage status and crop losses in some wheat cultivars, in wheat fields in Yozgat province and its districts in 2020. Larval infestation was recorded by examining the wheat stems collected from 36 wheat fields (2 m² area with 1/4 m² quadrat for each field). The damage caused by C. pygmeus in some wheat cultivars was recorded for 16 different cultivars and afterwards crop loss were noted for two bread (Ekiz, Esperia) and two durum (Eminbey, Kızıltan-91) wheat cultivars. Although infestation rates of wheat stem sawfly larvae varied according to the districts, the highest (25.6%) and the lowest (1.2%) infestation rate was recorded for Saraykent and Şefaatli districts, respectively. The effect of the pest on the spike length, number of grains per spike and grain weight varied according to the cultivars and larvae infestation rates. Crop losses due to weight reduction in grains varied between 0.2% (Esperia cultivar) and 5.9% (Ekiz cultivar). Considering larval infestation rate in stems and the weight reductions in the grains, it was determined that the crop losses due to the pest are ~1.5%, which means no economic losses are exerted by the pest currently. However, in areas with high larvae density, it would be appropriate to keep the pest population density under observation with periodic surveys starting from May.

  • Predacious activity of Serangium parcesetosum Sicard (Coleoptera:
           Coccinellidae) on Bemisia tabaci Genn. (Hemiptera: Aleyrodidae) on caged
           tomato

    • Authors: Ferda YARPUZLU; Mehmet KARACAOĞLU, Doğancan KAHYA, S. Emre GÖRÜR, Bülent ALTAN, Abdurrahman YİĞİT, Halil KÜTÜK
      Abstract: Tomatoes are the most familiar and the most common greenhouse vegetable crop in Turkey, as well as worldwide. Main whitefly species problematic in the greenhouses, where tomatoes grown primarily, is Bemisia tabaci Genn. (Hemiptera: Aleyrodidae) in Mediterranean Region of Turkey. Serangium parcesetosum Sicard (Coleoptera: Coccinellidae) is proved as a coccinellid predator of B. tabaci and a voracious feeder by several studies. The hypothesis “the outcome of a biological control program is determined by the initial pest to predator ratio” was examined on caged tomato in greenhouses. The current study showed the influence of initial whitefly density on the whitefly population growth rate, which was independent of the absence or presence of S. parcesetosum (P> 0.05) for the whitefly density × predator release interaction). No significant differences in whitefly suppression from S. parcesetosum predation were monitored between the two initial whitefly densities in both years. The density of the pest was reduced by S. parcesetosum in high and moderate initial whitefly density cages 2-3 weeks after releasing the ladybird beetles. During the experiment, copulating adults, larvae, and pupae of the predatory ladybird beetle were observed in both predator-releasing cages. These results indicated that S. parcesetosum can survive and reproduce on tomato plants in greenhouse production during the spring months in Mediterraenean region of Turkey.

  • Effects of The Exogenous IAA Applıcatıons on Salt Tolerance in Tomato
           (Solanum lycopersicum L.)

    • Authors: Serpil HAVADAR; Şebnem KUŞVURAN, Hayriye Yıldız DAŞGAN
      Abstract: In this study, the effectiveness of indole-3-acetic acid (IAA) applications in providing salt stress tolerance in tomato was investigated. TOM-141 (tolerant) and TOM-139 (sensitive) genotypes and AG5668 tomato cultivar were used as materials in the study. For stress plants, salt (200 mM NaCl) stress was initiated at 3 true leaf stages. Control plants were irrigated with nutrient solution. In IAA applications, 0.05, 0.25, 0.50, 0.75, 1.00 and 2.00 mM doses were used together with salt stress, and it was applied as a foliar spray once a week. Salt stress caused a decrease in plant growth parameters, YOSI, K and Ca ion concentration, total chlorophyll and carotenoid and total flavonoid content in tomato genotypes; Na and Cl ion concentration, MDA and total phenolic substance content increased. On the other and, in IAA applications with salt stress, on average 8-93% in fresh and dry weight; 7-65% in stem length and diameter; 22-329% in leaf number and area, 18-30% in YOSI values; 12-34% in K content; 9-37% in Ca content; 3-125% in total chlorophyll and carotenoid content; 7-107% improvement was achieved in total phenolic substance and flavonoid content compared to salt stress. This change was determined as 2-73% improvement in salt stress conditions in AG5668 tomato variety, 2-39% in TOM-141 genotype and 3-221% in TOM-139 genotype The decrease in Na, Cl and MDA levels at the genotype level with IAA application was 11-31% in AG5668, 12-21% in TOM141 and 16-35% in TOM 139. As a result of the study, it was determined that IAA applications improved the negativities caused by salt stress at varying rates and were effective in increasing tolerance, and 0.25 mm and 0.50 mM IAA applications came to the fore in terms of this positive effect among the applications.

Karacabey onion variety and İntfa Red Curly lettuce variety were used as herbal material. In the study, 0 (control), 500, 1000, 1500 and 2000 ppm doses of humic acid in liquid form named TKİ Hümas were evaluated. It was determined that different application doses of humic acid had statistically significant effects on some plant growth parameters and quality properties of green onion and lettuce. According to the findings obtained from the research, it was detected that humic acid significantly increased plant height, axis diameter, plant fresh weight, plant dry weight, root length, root fresh weight, root dry weight and dry matter rate in green onion; plant height, plant fresh weight, plant dry weight, root collar diameter and number of leaves in lettuce compared to the control. In general, it was determined that humic acid applications had positive effects on plant growth parameters and quality properties in both species. When compared to the control, it was found that plant fresh weight in green onion and lettuce increased by 7.07-28.82% and 15.61-48.94%, respectively, depending on the humic acid doses. When the humic acid doses were evaluated, it was detected that especially 1000 ppm dose in green onion and 500 ppm dose in lettuce were more effective on plant growth and quality.

  • Determination of The Grafting Performance of Some Hybrid Chestnut
           Genotypes and Cultivars

    • Authors: Burak AKYÜZ; Ümit SERDAR
      Abstract: This study has been carried out to determine the graft compatibility of newly registered some hybrid chestnut cultivars and genotype. The study was conducted between 2012-2018 at the Ondokuz Mayıs University and the Black Sea Agricultural Research Institute. In the study, ‘Marigoule’, Akyüz’, ‘Ali Nihat’ and ‘Macit 55’ cultivars were tested as scion and rootstock, and A41 genotype was tested only as rootstock. Grafting studies were carried out on generative rootstocks in 2014 and mother plants in 2015 using the chip budding method. Graft success (%) was determined 30 days after grafting and survival ratio (%) at the end of the vegetation period. Also rootstock, graft area and scion diameter were measured at the end of the vegetation period by digital caliper. As a result of the study, graft success and survival ratio were low in combinations created with ‘Ali Nihat’ and A41 generative rootstocks. Among the plants, the best generative rootstock was the ‘Macit 55’ cultivar in terms of graft success and survival ratio. ‘Macit 55’ rootstock had good graft compatibility with both itself (‘Macit 55’), ‘Akyüz’ and ‘Ali Nihat’ cultivars. ‘Marigoule’ cultivar has generally shown severe graft incompatibility with complex hybrids tested in the study. In the grafts made on clone plants, the ‘Ali Nihat’ rootstock was determined as a good rootstock for itself (‘Ali Nihat’), ‘Akyüz’ and ‘Macit 55’ cultivars.
