    • Authors: Gülay ZULKADİR
      Abstract: The aim of the study is investigate the effects of hidropriming on germination performance of white clover (Trifolium repens) seedsunder cold stress, optimum temperature and dark condition. The seeds were germinated applying hidropriming with dH2O in different periods (2, 4, 6, 8, 16, 18, 20, 22, 24 and 48 hours) in dark at 4 oC. The study was applied in according to randomized controlled trials as 4 replications to measure radicular lengths, germination rate and homogeneity parameter in the seeds. The results of the study was indicated that radicle length, germination rate, rate and the homogeneity parameter were positive and statistically significant (P<0.001) comparing with control group in short period (2 and 4 hours). On the other hand radicle length, germination rate, the homogeneity parameter were found negative and statistically significant when compare with control group in the other periods (P<0.001). In addition, this study was discussed possible physiological effects to the priming process implemented with dH2O in hypothermia condition at white clover seeds.

  • The application of fish wastewater to improve the plant growth,
           development and yield of lettuce (Lactuca sativa L.)

    • Authors: Abdullah ULAŞ; Yusuf Cem YÜCEL, Firdes ULAŞ
      Abstract: Demand for low-cost and affordable alternating sources of plant nutrient responses to boost the nutrient level of damaged arable farmlands has been a main concern for soil scientists, agronomists, and local farmers. The objective of this study is to investigate the effect of fish wastewater on the growth parameters, yield, and biomass productivity of lettuce (Lactuca sativa L.) as compared by using in aerated nutrient solution under deep water culture (DWC) technique. The experiment was carried out to investigate shoot and root fresh and dry weight, total leaf number, leaf chlorophyll content (SPAD), photosynthesis, leaf total chlorophyll (a+ b), leaf total carotenoid content, total leaf area, leaf NRA activity, total root length, root volume and average root diameter. Lettuce plants were examined by using an aerated deep-water culture (DWC) technique in a fully automated climate room for six weeks. The seedlings were transplanted onto 8 L continuously aerated pots containing mix of different ratios of fish effluent water with tap water with six different treatments (T1, T2, T3, T4, T5 and T6) and replicated three times. The fish wastewater effluents did not reduce the growth of lettuce plants. Shoot and root fresh and dry matter, total leaf number, leaf total chlorophyll (a+ b), leaf total carotenoid content, total leaf area, leaf NRA activity, total root length, root volume and average root diameter of lettuce plants were significantly increased with under T3 treatment (Tap water + 1.5 mM N + 50 ml Nutrient solution + 8 ml Fe + 1000 ml Fish effluent water). However, the lettuce plants grown under T4 treatment (Tap water + 1.5 mM N + 250 ml Fish effluent water) had the lowest shoot and root fresh matter, total leaf number, photosynthesis, total leaf area, leaf NRA activity, total root length, root volume and average root diameter. The compost derived from the fish wastewater plays an important role in supplying the nutrients for cultivating the lettuce plants. Also, in this study appreciable nutrients were significantly obtained in treatments treated with fish wastewater, as compared with the ground (tap) water. Thus, grown lettuce with aquaculture is a good source of nutrition for human consumption.

  • Impact of climate on durum wheat yield (Triticum durum Desf.) under
           different cultivation and irrigation methods

    • Authors: Öner ÇETİN; Cuma AKINCI, Önder ALBAYRAK, Muhittin Murat TURGUT, Remzi ÖZKAN, H. Kıvanç DOĞANAY
      Abstract: This study was aimed to determine the effects of different cultivation and irrigation methods on wheat in 2017-2018 and 2019-2020. The experiment design was the split-plots in randomized blocks with 3 replications. The main plots were conventional flat cultivation (CFC) and raised-bed cultivation (RBC), and sub-plots were rain-fed conditions, surface irrigation and drip irrigation. The CFC and RBC resulted in the grain yield of 5.13 and 4.33 t ha-1, respectively. The grain yield of 5.21 and 5.55 t ha-1 were obtained by surface irrigation and drip irrigation, respectively. The yield in CFC (16%) and drip irrigation (6%) were relatively higher than RBC and surface irrigation. Irrigation water productivity (1.72 kg m-3) in RBC was higher compared to 1.23 kg m-3 in CFC. The irrigation water applied was 468 and 258 mm in CFC and basin irrigation and in RBC and drip irrigation, respectively. Crop evapotranspiration was 813 and 725 mm in CFC and the basin irrigation, and in RBC under the drip irrigation, respectively. The CFC under basin irrigation was more appropriate compared to RBC and drip irrigation. Insufficient and improper distribution of rainfall and temperatures more than 30 oC caused lower yield.

  • Evaluation of performance indicators for some drip irrigation systems used
           in cherry orchards in Ankara province

    • Authors: Rohat GÜLTEKİN; Ceren GÖRGİŞEN, Gonca KARACA BİLGEN, Pınar BAHÇECİ ALSAN, Tuğba YETER
      Abstract: In this study, performance tests of drip irrigation systems were carried out in cherry orchards of some farmers in Ankara. Accordingly, measurements were made on the day of irrigation in the lateral and manifold pipes of the drip irrigation systems used by the farmers. Within the scope of the research, Distribution Uniformity, Emission Uniformity, Application Efficiency, Potential and Actual Application Efficiency measurements were made in drip irrigation systems in 10 different cherry orchards. For this purpose, 4 different dripper points were determined on at least 4 lateral lines in each manifold line. Each lateral pipe and dripper point was chosen to be at the beginning of the line, 1/3 of the line, 2/3 of the distance and at the end of the line. Measurements were made on farmers’ irrigation days and under farmer conditions. According to the obtained results, the CU value was between 77.5%- 93.0%, DU value between 60.1%- 86.9%, EU value between 56.7%- 84.5% and CV value between 0.09- 0.28. As a result of the research, it has been determined that there are important design and application problems in drip irrigation systems.

  • Morphological characterization of some Besni pepper (Capsicum annuum L.)
           genotypes in Kayseri conditions

    • Authors: Mirac SAHİN; Halit YETİŞİR, Hasan PİNAR
      Abstract: The pepper genetic resources, which is a widely produced and consumed vegetable in Turkey and the world, are faced with some threats arising from the environmental conditions and agricultural activities. Therefore, it is very important to protect pepper genetic resources and include them in breeding programs. During the production adventure of pepper in Turkey, pepper genotypes known by the name of the regions were developed in different regions such as Demre, Uşak, Karaisalı, and Arapkir pepper. One of them, Besni Pepper, is grown in and around Besni district of Adıyaman province and makes significant contributions to the regional economy. In this study, 26 pepper genotypes collected from the villages of Besni and Gölbaşı districts, and three control varieties were characterized according to 42 morphological traits. Pepper genotypes showed significant variation in terms of the characteristics considered. Principal Component Analysis (PCA) was applied to the investigated traits. The PCA analysis yielded 10 principal components explaining 86% of the total variation. The eigen values of 10 PC’s varied from 10,50 to 1,10. The first three PC’s explain 51,20% of the total variance. The variation between genotypes is mostly due to fruit characteristics such as fruit shape, fruit size, and blossom end shape. While the genotypes were divided into 4 groups in the cluster analysis, the pepper varieties used as control were separated from all genotypes and formed a separate group.

  • Leaf and root-growth characteristics contributing to salt tolerance of
           backcrossed pepper (Capsicum annuum L.) progenies under hydroponic
           conditions

    • Authors: Firdes ULAŞ
      Abstract: The aim of this study was to determine the genotypic differences in salt tolerance of third back-crossed peeper progenies and their respective parents through examining the changes in the shoot growth at agronomical, root growth at morphological and leaf development at physiological levels under salt stress. A hydroponic experiment was conducted by using an aerated Deep-Water Culture (DWC) technique in a controlled growth chamber of Erciyes University, Agricultural Faculty in Kayseri, Turkey. Five pepper plants (BC3-1, BC3-2, BC3-3, BC3-4, BC3-5) were selected from the third backcrossed (BC3) progenies of Sena and Kopan. Plants were grown in 8 L pots filled continuously aerated nutrient solution under at two electrical conductivity (EC) levels (control at 1.0 dS m−1 and salt at 8.0 dS m−1) in RBD design with four replications for six weeks. Significant reductions in leaf, shoot and root fresh and dry biomass productions, total leaf area, total root length, and total root volume of pepper plants were recorded under hydroponic salt stress. On the other hand, significant differences in salt tolerance among backcrossed peeper progenies and their respective parents existed. Particularly the progeny of BC3-3 was more tolerant characterized to salinity than the other progenies of third backcrossed and their respective parents. This was highly associated with vigorous root growth (root fresh and dry weight, total root length and volume) and photosynthetically active leaves (total leaf area, leaf chlorophyll index, chloride exclusion) under hydroponic salt stress. These traits could be useful characters to select and breed salt-tolerant pepper varieties for sustainable agriculture in the future.

  • Immunomodulation function of Tunceli garlic (Allium tuncelianum) oil in
           Rainbow Trout (Oncorhynchus mykiss)

    • Authors: Ünal İSPİR; Mikail ÖZCAN, Engin ŞEKER
      Abstract: The effects of injectable Tunceli garlic oil (Allium tuncelianum) on serum response of rainbow trout were examined. Influence of intraperitoneal (i.p.) injection administration of Tunceli garlic oil (TGO) was evaluated on some immunological factors of rainbow trout. Fish weight 40 g were i.p. injected TGO at doses of 1% and 10%. Serum lysozyme activity, bactericidal activity, myeloperoxidase, protein and immunoglobulin levels were measured on days 3, 7, 14 and 21 after the TGO administration. All the immune parameters assayed remained affected when TGO was i.p. administered. Serum bactericidal activity was consistently achieved by immunizing fish with TGO. Levels of serum myeloperoxidase activity were increased in the groups of fish injected with TGO. Myeloperoxidase and bactericidal activities peaked at 14 and 21 days post-injection, respectively. Lysozyme activity was significantly increased throughout experiment in the all groups. Total protein and immunoglobulin levels increased in the 21 days post-injection although no statistically significant differences. In conclusion, these results suggest that there are functionally effects of TGO on the immune mechanisms of rainbow trout.

  • Application of swat hydrological model to assess the impacts of land use
           change on sediment loads

    • Authors: Rouhollah NASİRZADEHDİZAJİ; Dilek Eren AKYÜZ
      Abstract: Controlling and reducing the watershed's erosion and sedimentation is essential to ensure the continuity of projects implemented to develop land and water resources and improve sustainability, performance, and longevity. Sediment control is also critical in managing the river basin in limiting the transport of solids, improving water quality, sustaining aquatic life, and preventing damage to downstream aquatic environments and ecosystems. Estimating the potential effects of land-use changes on surface runoff and soil erosion requires distributed hydrological modeling methods. In addition to naturally occurring sediments, changes in land-use types for different applications can be a primary cause for the increase in sediment rates in the watershed. This study used the Soil and Water Assessment Tool (SWAT), a rainfall-runoff model, to evaluate land use/cover changes (i.e., deforestation) and their impact on sediment load under different scenarios. For the baseline (no changes) scenario, the watershed is calibrated using the flow and sediment data measured from the rain gauge station during the time step to estimate the post-deforestation changes at the sub-catchment scale of the study area. The study results indicated that the total surface runoff and sediment yield for the selected sub-catchment in the deforestation scenario with the highest spatial distribution, due to the high erosivity (24% increase) of excessive surface runoff after deforestation, sediment yield increased 3.5-fold. In contrast, due to the removal of trees and vegetation's canopy, the evapotranspiration, leaf area index, and dissolved oxygen transported into reach showed the inverse ratios, and the values decreased by 5%, 24, and 17%, respectively, in compared with the baseline scenario. In terms of watershed management, therefore, the application of hydrological models such as SWAT rainfall-runoff and erosion models can be a helpful method for decision-makers to apply for the protection of forests from intensive impacts such as deforestation and limiting their socio-environmental effects.

  • Pitfalls and prospects of contract farming to smallholder tobacco farmers
           in Shamva district, Zimbabwe

    • Authors: Lawrence MANGO; Andrew Tapiwa KUGEDERA
      Abstract: The objective was to assess the challenges and opportunities of contract farming to smallholder tobacco farmers in ward 27, Shamva District, Zimbabwe. Data on demographics, household endowments and economic and social achievements from tobacco production was collected using questionnaires and interviews. A systematic sampling technique was used in selecting the tobacco farmers. Data was analysed using SPSS version 26. The results show that 93.9% of the participants were males and most of the participants were educated to primary level (36.4%). Zimbabwe Leaf Tobacco Company (43%) was cited as the major company which provide contract farming to tobacco farmers in ward 27. The results further indicated that there are more opportunities received by tobacco farmers such as receiving inputs at no cost but face challenges such as poor crop yields due to low producer price (55%), high cost of production (30%), low rainfall (9%) and shortage of firewood (6%). Some participants indicated that they do not have technical knowledge on how to use chemicals and in identifying pests so that they apply the correct chemicals. It is recommended that companies which provide contract farming must collaborate with the Ministry of Agriculture and further train farmers on financial management skills, how to use chemicals and pest identification so that the quality of the leaf is improved. Nevertheless, contracting companies should provide tillage services to farmers and ensure that farmers are included in price determination.

  • Investigation on the effects of cooking methods on anti-inflammatory and
           antioxidant activities of five mostly consumed vegetables in winter

    • Authors: Tuğba İDUĞ; Hilal HIZLI GÜLDEMİR, Ali ŞEN, Osman GÜLDEMİR
      Abstract: The aim of this study is to investigate the effects of steaming and boiling on antioxidant and anti-inflammatory activity of five frequently consumed vegetables in winter. The vegetables were prepared by three different cooking methods including steaming, 5-minute boiling, 15-minute boiling to compare with their raw forms. Antioxidant capacity was measured with 1, 1-diphenyl–2 picrylhydrazyl (DPPH) radical scavenging method, anti-inflammatory activity was measured with 5-lipoxgenase inhibitory method, and the total phenolic content was detected after in vitro cooking process. The highest antioxidant activities among the raw vegetables were found in spinach (SR) (425.80 µg/mL, 12.83 mg/g) and broccoli (BR) (754.50 µg/mL, 7 mg/g). While boiling for 15 minutes and steaming slightly increased the antioxidant capacity in spinach and decreased it in broccoli; the highest activities among the mentioned cooking methods and vegetable samples were detected in these two vegetables. The lowest antioxidant activities were determined in leek (LR) (5662.0 µg/mL, 1.24 mg/g) and celery (CeR) (2796.0 µg/mL, 2.98 mg/g). In addition, the least affected vegetable from the cooking methods was spinach (S) (227.4-549.8 µg/mL). Cooking techniques have significative effects on the levels of phytochemical compounds and antioxidant capacities. It was observed that cooking methods increased the anti-inflammatory activity of the vegetables used in this study. Only broccoli (B) showed a decrease. The highest anti-inflammatory activity was found in the leek (L15) which was boiled for 15 minutes. Also, our results contribute to the databases that provide information about the effects of different cooking techniques on the antioxidant and anti-inflammatory potential of vegetables.

           entomophagy

    • Authors: Zeynep BAKKALOĞLU
      Abstract: Generally, in the world edible insects have gained popularity and awareness among people. Therefore, the study on Turkish consumers' attitudes and consumption towards entomophagy has important findings. The relationships edible insects with sociodemographic effects, demand to eat and personality traits of participants were determined by online questionnaire method. According to the results, most of the participants have not consumed edible insects before and furthermore both male and female consumers were not found to be positive tendency for eating edible insects. The main factors of rejection behaviors are disgusting, food neophobia and some health and religious concerns. However, a few participants have already consumed edible insects and have mainly exhibited this experience in abroad. Thereby, the study suggests that familiarity and awareness are the most significant factors changing attitudes towards to edible insect consumption for Turkish consumers. To determine consumption behavior and preferences of Turkish consumers, the most significant factors are overpassing the psychological barrier such as neophobia and facilitate entomophagy acceptance. This study could enable the development of strategies to increase desire of eating EI (edible insects) by Turkish consumers and promote insect production.

           Diyarbakır, identification of problems and solutions

    • Authors: Murat TURAN; Ali Murat TATAR
      Abstract: The present study aimed to determine the current state of water buffalo breeders in Silvan, Bağlar, Yenişehir, and Sur counties of Diyarbakır province in Turkey, and to reveal the aspects of shelter, grazing, calf breeding, brood use, meat and milk production practices, care and health protection, expectations from breeding practices and current problems. The results of the face-to-face surveys were used carried out with a total of 147 business owners engaged in water buffalo breeding in four counties. In the research, the average number of water buffaloes per farm was determined to be 11.03. The breeders have reported that they continue to raise water buffaloes for reasons such as making a living, high quality of water buffalo milk, and benefiting from the available subsidies. The average lactation period of water buffaloes was 7.1 months, the average daily milk obtained per animal was determined to be 3.63 liters. The milk obtained is mostly evaluated as yogurt, cheese, and butter. As a result, it was determined that almost all of the breeders are satisfied with water buffalo breeding, they see breeding as a family profession, and they are aware of the quality and importance of water buffalo products.

  • Evaluation of genetic structure of pistachio through whole genome
           resequencing

    • Authors: Harun KARCI; Salih KAFKAS
      Abstract: Pistachio (Pistacia vera L.) is the only edible and cultivated species. Pistachio is the only economically importance and dioecious species in the genus Pistacia. There are basic problems in pistachio breeding such as dioecious flower structure, long juvenile period and alternate bearing. These problems can be overcome not with classical breeding methods, but with modern molecular breeding methods. In this study, very high numbers of single nucleotide polymorphism (SNP), insertion/deletion (InDel), structural variants (SV) and copy number variation (CNV) were determined by using the next generation sequencing data of the pistachio genotype obtained with 15x sequencing coverage. A total of 1,785,235 SNP, 260,683 InDel, 5,227 SV and 1,914 CNV variants identified in PvF217 pistachio genotype. The variant density was calculated as one variant per 292 base. The distribution of the obtained variants to the Siirt reference genome was obtained. In addition, all variants were annotated to the reference genome and exonic and genomic variants were described using Annovar. These data will be used to consist of a molecular database in pistachio breeding for DNA fingerprinting, discovering unique cultivar specific alleles and to identify quantitative trait loci related to important nut traits.

  • Genetically modified organisms and biosafety as perceived by professionals
           according to their sociodemographic characteristics

    • Authors: Selda TÜRKOĞLU COŞKUN; Emine OLHAN
      Abstract: While the cultivation of modern biotechnology products was adopted by producers very fast, the consumer acceptance of these products has not evolved at the same pace. Despite multiple benefits associated with genetically modified organisms (GMO), some potential risks related to the environment, health and economy have increased concerns and affected consumer confidence. This article examines the relationship between knowledge and confidence levels for biosafety and GMOs, and the sociodemographic characteristics of professionals working in the fields of food, agriculture and veterinary medicine, with a view to assess their perception. Questionnaires were applied to 261 individuals, selected by the proportional sampling method among professionals, the numbers of whom were obtained from the relevant unions and chambers. Then frequency, percentage distribution and factor analyses were carried out on data obtained. In conclusion food engineering professionals, men and more knowledgeable participants in biotechnology were found to have a more positive approach towards GMOs and more confidence in the biosafety system. It is indisputable that the scientific knowledge is essential for a reliable biosafety mechanism. Therefore, the inclusion of courses on GMOs and biosafety into curricula and planning in-service trainings may significantly contribute to the development of scientific knowledge thus, improving attitudes towards GMOs.

  • Adsorptive removal of cationic dye from aqueous solutions using
           Bardakçı clay

    • Authors: İhsan ALACABEY
      Abstract: This study was investigation employed the batch adsorption method using Bardakçı Clay/Van as an adsorbent to remove crystal violent, a cationic dye from an aqueous solution. The effects of pH, adsorbent amount, interaction time and concentration were investigated to determine the optimal adsorption conditions. The optimal adsorption conditions were determined to be pH=6, 0.6 g adsorbent amount, and the adsorption reached equilibrium at the 25th minute. The equilibrium isotherm was determined using the Langmuir, Freundlich and Dubinin–Radushkevich (D–R) adsorption equations. It was discovered to conform to the Langmuir isotherm. In the Dubinin-Radushkevich (D-R) model, the E value was calculated to E< 8 kJmol-1, indicating that the adsorption process occurs physically. Thermodynamic parameters such as enthalpy (ΔHo), Gibbs' free energy (ΔGo) and entropy (ΔSo) were calculated. The adsorption of crystal violet with Bardakçı clay demonstrated that the process was endothermic, occurring both physically and spontaneously.

  • Assessment of nematicidal activity of Beauveria bassiana (Bals.-Criv.)
           vuill on Pratylenchus thornei (Sher et Allen) (Tylenchida: Pratylenchidae)
           

    • Authors: Fatma Gül GÖZE ÖZDEMİR; Asiye UZUN, Ozan DEMİRÖZER
      Abstract: In this study, nematicidal activity of two different isolates (BY2 and BIM-001) of the Beauveria bassiana (Bals.-Criv.) Vuill was investigated on Pratylenchus thornei Sher et Allen) (Tylenchida: Pratylenchidae) using culture filtrates and spore suspensions. Three spore suspensions (1x106, 1x107, 1x 108 spore/ml) and four culture filtrate concentrations (1X, 10X, 20X, 50X) were tested in the study. Depending on the treatment; 2 ml of spore suspensions or culture filtrates in different concentrations of both isolates and 400 larvae+adults from P. thornei were transferred to 6 mm petri dishes. The dead nematodes were counted under a light microscope after 24 and 72 hour and their mortality rate (%) were calculated. The nematicidal effect of culture filtrates of B. bassiana BY2 and BIM-001 isolates on P. thornei was found to be higher than the spore suspension. It was determined that the 1X concentration of culture filtrate of B. bassiana BY2 reached 100% mortality rate on P. thornei after 24 hour. After 72 hours, 10X (99.0%) concentrations of BY2 isolate and 1X (100%) and 10X (93.2%) concentrations of BIM isolate showed similar nematicidal activity with the commercial nematicide Velum (97.6%). On the other hand, after 72 hour, P. thornei mortality rate was 75.5% and 64.1%, respectively, at a concentration of 108 spore/ml of B. bassiana BY2 and BIM-001 isolates. This study will contribute to the development of a new control method as an alternative to the use of crop rotation and resistant cultivars in the control of P.thornei.

    • Authors: Solmaz KAMAŞAK; Ömer Faruk COŞKUN, Akife DALDA ŞEKERCİ, Osman GÜLŞEN
      Abstract: Conservation of genetic resources is essential for the continuation of future crop production. Watermelon (Citrul-lus lanatus), a member of Cucurbitaceae, is widely distributed in tropical and subtropical regions. The aim of this study was to reveal the genetic relationships with the help of microsatellite markers in a watermelon collection free of unnecessary repetitions, and to determine the success of SSR (Simple Sequence Repeats) primers developed in cucurbits. In this study, 96 watermelon genotypes with good agronomic characteristics were used among the geno types collected from different regions of Turkey and purified up to the S4-S6 (self-pollination) stage. In the study, 33 SSR primer pairs were used to determine the genetic relationship between watermelon genotypes. In the study, a total of 67 bands were obtained with SSR primers. As a result of UPGMA (Unweighted Pair Group Method Using Arithmetic Averages) analysis, genotypes showed similarity at the level of 0.84-1.00. The number of alleles detected per primer varied between 1 and 6. In terms of the total number of alleles obtained, CMCT44 (5 units) and Cgb4767 (6 units) loci produced the most alleles. Primers with high polymorphism rate and allele excess were determined, and the possibilities for use in genetic stability analyses, variety differentiation and other genetic analyses were determined.

  • Determining the future trends of safflower plant in Türkiye

    • Authors: Mustafa AKGÜN; Erkan SÖYLEMEZ
      Abstract: The aim of this study is to reveal the current situation of safflower in Türkiye, to make future forecasts about safflower planting area, production quantity, yield and producer prices. The Double Exponential Smoothing Method was used in time series analysis for future forecasts. The time series used were obtained from FAO and TUIK statistics. Five-year (2022-2026) future projections were made for the planting area, production quantity, and yield using safflower data between 1988-2021. For the producer prices, the data between the years 2004-2021 were used. According to the results of the study, it is forecasted that in the next 5 years, there will be a reduction average of 54 decares of safflower in the planting areas and an average of 515 tons of reduction in the production quantity each year. Producer prices are expected to increase by an average of 20% per year. Although it is predicted that there will be a very small increase in yield for each year, it is predicted that there will be a 2.5% yield increase at the end of 5 years. In order to prevent the decrease in safflower production and to increase production, it is recommended to provide purchase guarantee to producers, to support entrepreneurs, to carry out studies on modern cultivation practices, marketing and promotion.

  • Impact of seed priming on germination performance of fresh and aged seeds
           of Canola

    • Authors: Sibel DAY
      Abstract: Priming fresh and naturally aged canola seeds with different substances and observing the seed germination properties are involved in this work. Fresh seeds and aged seeds of canola cv. “süzer” were treated with distilled water, -0.8 MPa polyethylene glycol (PEG) 6000 and 50 mM thiamine for 8 hours. Storage of canola seeds showed the loss of germination capacity compared to fresh seeds. Present findings indicate that priming can improve germination and germination speed both in fresh and aged seeds of canola. Germination percentage increased in aged seeds with distilled water priming and thiamine priming. Mean germination times were lower in the primed seeds. Seedling growth didn’t improve with priming in both ages. It was concluded that germination performance improvement of aged seeds is possible with suitable priming.

  • Determination of sowing date of Crambe (Crambe abyssinica L.) in Northern
           Türkiye

    • Authors: Orhan KURT; Merve GÖRE, Kübra KIR
      Abstract: This research was carried out by sowing it in the winter season in 2019-2020 in order to determine the effects of sowing dates on some agricultural and technological characteristics of the crambe in Samsun ecological conditions. The research was carried out with 3 replications of divided plots in randomized blocks and crambe genotypes (NSL-74257 and PI-384530) were placed in main plots and sowing dates (October 17, November 1, November 16, December 1) were placed in subplots. Research result; the plant height was 72.28-83.62 cm, the number of seeds per plant was 668.73-842.54, the weight of 1000 seeds was 7.34-8.54 g, the seed yield per plant was 4.84-8.54 g. In addition, it was determined that the oil yield per plant was between 1.72-3.26 g and the oil ratio was 35.00-36.17%. Considering all the characters evaluated; It was determined that the first sowing date (17 October) is more advantageous than other sowing dates (1 November, 16 November and 1 December). However, since the data obtained are the results of field conditions and only a one-year study, it was found very early to establish a definite opinion on the effects of sowing dates on the characters studied. For this reason, it has been decided that it would be beneficial to continue the research for at least one more year in order to make an evaluation about the sowing date of the crambe in Samsun ecological conditions.

  • Poultry manure effects on yield and some agronomic components of Soybean
           (Glycine max L.) under Khost agro-ecological conditions, Afghanistan

    • Authors: Ahmad Yar AHMADİ; Mohammad ARİEN
      Abstract: Soybean [Glycine max (L.) Merrill], which has the highest protein content of all food crops, is the world’s leading source of protein and oil. Soybeans are commonly consumed by humans in the form of soymilk, soy protein, tofu, infant formula, miso, natto, soy flour, and soy sauce. They are a popular protein-rich food source in most Asian countries. Worldwide, approximately 85% of soybean's produce has been processed into soy food. While in developing countries like Afghanistan, limited farmers used inorganic fertilizers in soybean fields through the high cost, marketing problems and poor economic conditions. If we have alternative resources for soil fertility like organic manure, this problem can somewhat be solved. The objective of this study was to test the effects of different levels of poultry manure on the yield and yield components of the soybean crop. The field experiment was conducted in 2019 in Almara Village of Nadar Shah Kot District of Khost Province. Soybean variety LD04-13265 was grown with four levels of manure (0, 1, 2, and 4 tons ha-1) using Randomized Complete Block Design with three replicates. Results revealed that manure invariably influenced most parameters under study. The highest grain yield (1212.95 kg ha-1) was obtained with 4 tons ha-1 (T3) followed by T2 and T1 (1145.16 and 1138.24, respectively). Poultry manure also had positive effects on the agronomic characters. Plant height, number of branches, pods plant-1, seed pod-1 were among the most affected. Correlation analysis revealed significant positive correlations among the grain yield and yield components but non correlation was found for 100 seed weight with other observed parameters. As per the results of this research, 4 tons of poultry manure is the optimum amount to be used for soybean production.
