This research was carried out to determine the pollination abilities of Domat, Gemlik and Sarı Ulak olive cultivars. Pollen viability rate, germination rate and amount of pollen production were examined during the periods when 25%, 50% and 75% of the flowers were opened. According to the results obtained from three years’ experimental study, the highest percentages of pollen viability were found in Gemlik (81.51%) and Domat (81.50%), whereas Sarı Ulak cultivar (77.41%) showed the lowest viability. In pollen germination percentages, the highest values on the basis of cultivars were determined 59.85% (Domat), 59.74% (Gemlik) and 52.12% (Sarı Ulak). The highest amount of pollen production in a flower was found in the Sarı Ulak cultivar (329,046) while it was followed by Domat (319,693) and Gemlik (306,385). Despite the high pollen production in Sarı Ulak cultivar, the pollen viability and germination rates were found to be low. In Gemlik and Domat cultivars, all values were obtained relatively near. In addition, it had been noted that the values related to pollen viability, germination and production amount were higher during 50% and 75% flowering periods than 25%.

The belief that ancient wheat is more beneficial than common wheat has been growing trend in recent years among the consumers. The present study aims to compare bioactive peptide, allergen peptide and toxic peptide generation after gastrointestinal digestion of modern wheat (Triticum aestivum) and ancient wheat, einkorn (Triticum monococcum var. monococcum), using in silico tools. The primary sequences of both kinds of wheat were obtained from BIOPEP-UWM and UniProtKB/Swiss-Prot database. In silico digestion was applied using BIOPEP-UWM online tool. For the simulation of gastrointestinal digestion pepsin (pH 1.3) (EC 3.4.23.1), trypsin (EC 3.4.21.4), and chymotrypsin (EC 3.4.21.1) were selected and analyzed. Homology analysis was performed for each protein sequences using EMBOSS Needle program. Toxic and allergen peptides were predicted using ToxinPred online tool and Allergen FP v.1.0. The results showed that einkorn and common wheat proteins exhibited similar properties including high similarity rate (58.72-87.40%) indicating the percentage of matches between the two sequences and the identical bioactivities for peptides generated after digestion. Most of the bioactive peptides were dipeptides and the majority of them displayed more than one bioactivities including ACE inhibitory, DPP IV inhibitory or antioxidant activity, etc. Allergen peptides generated after in silico digestion were found to be similar for both kinds of wheat. In silico gastric digestion of einkorn and wheat caused toxic peptides production, but they were disappeared after in silico intestinal digestion. In conclusion, although there is a perception related to the Einkorn that is healthier than common wheat, in silico digestion of common wheat and einkorn did not support this perception.

The depletion of minerals in agricultural soils through subsistence farming has been a major food security challenge in many parts of the world. To curtail this problem, farmers use inorganic fertilizer to boost soil fertility even though it poses a lot of environmental challenges. In this research, an alternative route to soil nutrient amendment was explored via the use of compost and nano-gel water accumulator for blending different soil samples derived from rock side soil and spent farm soils blended in different ratios of 1:0, 1:1, 1:2, and 2:1using a suitable potting media for the greenhouse production of A. spinosus L. Physicochemical values, mineral, and heavy metals concentration were evaluated on the soil and compost samples while mineral, proximate, anti-nutrients and vitamins compositions were analyzed on A. spinosus L. grown on the soils. Data obtained were analyzed using analysis of variance (ANOVA) at a 95% confidence limit using SPSS 20.0 software. The properties of the prepared compost (PC) and commercial compost (CC) varied significantly (P

Climate Smart Agriculture (CSA) is a global strategy for enhancing food productivity amidst climate change uncertainties in the 21st century. CSA improves farmers’ incomes, reduces greenhouse emissions, and farming systems become resilient to climate change. Despite the vital role that CSA plays in the development of the agricultural industry and the economy, the extent to which CSA is related to sustainable agriculture (SA) is not well documented. Is CSA the same as SA? If they are the same, do CSA practices impose mitigation requirements for developing countries like Uganda? Studies or research on CSA and SA unfortunately have certain shortcomings. Lack of this knowledge makes it difficult to plan investments and develop policies that will increase farmers’ resilience to climate change and variability to improve SA. This study is aimed at assessing how CSA links to SA and whether the two contribute to climate change mitigation requirements. It was found that CSA and SA are also related in a way that the latter leads to lowering greenhouse gas emissions hence mitigating climate change. CSA and SA share a common principal goal of achieving food security. It was concluded that developing countries are the worst affected by the negative impacts of climate change and don’t have the adaptive capacity to respond to climate change effects.

Honey, bee venom, royal jelly, pollen, propolis and other bee products are natural products that are used to protect and maintain human health, to create a strong and dynamic health condition, and used as a ethnopharmacological medicine in the therapy of some illness. The use of different bee products to strengthen the immune system is still very common today. In this study, it was aimed to determine the in vitro effects of royal jelly samples collected from Sivas province in HUVEC cell culture conditions by determining the healing endothelial damage. In this context, royal jelly samples were obtained from the province of Sivas, where beekeeping is carried out intensively and successfully, in the 2022 harvest period. The effect of royal jelly extracts on the cell proliferation of endothelial cell culture was investigated. Repair of endothelial cell damage, cell growth and development and migration values were measured using the HUVEC cell line, and the data were evaluated with SPSS, GraphPad, ImageJ programs. Although there were significantly important increases in cell growth, development and cell viability values in HUVEC cells treated with different doses of royal jelly at the end of 24 and 48 hours, no statistically significant difference was found in terms of cell migration ratio compared to the control group.

The present study, it was aimed to determine the effect of antioxidants added to culture media on blastocyst development rates in in vitro embryo production. The material of the study consisted of oocytes collected from the ovaries taken from the slaughterhouse. Cumulus oocyte complexes (COC) were collected and classified under a stereomicroscope. Oocytes included in the study were subjected to maturation and fertilization stages. Probable zygotes were transferred to the culture (IVC) containing antioxidants (L-ergothionine 100 μM (n: 163), Vitamin E 100 μM (n: 151) Cysteamine 50 μM (n: 154) and were cultured in a tri gas incubator (Hera Cell- 6% O2%, 6%CO2, 88%N). Blastocyst rates and embryo quality were determined on the 6th and 7th days in culture medium. Differences in IVMFC stages were evaluated by chi-square test. 966 oocytes were collected from 162 ovaries collected from the slaughterhouse. It was determined that the number of oocytes per ovary was 5,96, and the number of A and B quality oocytes was 4.26. It was determined that 655 (94.93%) of a total of 690 oocytes undergoing in vitro maturation were mature. The cleavage rates of the groups were 83.44%; 80.79%; 79.87%, and 83.96%, respectively. 140 (21.37%) blastocysts were obtained from 655 oocytes taken into the culture stage and the blastocyst rates in the groups were 33.13%; 8.61%; 7.79%, and 32.62%, respectively. As a result of the study, it was determined that the rates of blastocysts in the L-ergothioneine added the group was similar to the control group, but the blastocyst rates decreased significantly in the cysteamine and Vitamin E added groups. It was thought that this decrease might have been affected by the dose of antioxidants or the adequacy of oocyte development

In the background of improving Water Productivity, there is concern in deficit irrigation, which delivers a means of decreasing water depletion while reducing opposing effects on yield. A field experiment was conducted at Haramaya, Ethiopia during 2020 off-season. The objective was determining effects of irrigation levels and mulch types on yield and Water Productivity of Onion. The experimental design was a split plot in RCBD with three replications. The deficit irrigation levels 100%, 85%, 70% and 55% ETc used with the three mulch types no mulch, straw and white plastic mulch were used. The results revealed that the maximum yield of 38.43 ton ha-1 was recorded from 100% ETc with plastic mulch; whereas the minimum yield of 16.36 ton ha-1 was recorded from 55% ETc with no mulch. Higher Crop Water Productivity of about 9.04 kg ha-1mm-1 was obtained from 85% ETc with plastic mulch. With 85% ETc and plastic mulch the water saved, yield reduction and Crop Water Productivity were 113.13 mm, 9.57% and 9.04 kg ha-1 mm-1 respectively. In view of water saved and maximum yield, irrigation water application at 85% irrigation application levels and plastic mulch could be concerned. The current study recommends that, in water limited area, farming community can accept deficit irrigation level with 85% ETc under plastic mulch.

We, here, aimed to determine the presence of Anguillicola crassus, a swim bladder parasite, in 89 (male: 45, female: 44) dead European eel specimens obtained seasonally between 2020-2021 from a regional fisherman, who has fished with fyke net in the locality Tuzla of Izmir Bay, Eastern Aegean Sea. Out of 21 male European eels caught in winter, only one specimen (TL: 48.5 cm and TW: 247.12 g) had 23 swim bladder parasites (adult nematodes: 15, larvae: 8) and similarly, only one parasite was found in one specimen (TL: 37.5 cm and TW: 88.47 g) of 8 eels caught in spring. No parasite was found in the female eels. At the examinations, it was determined that all adult Anguillicola crassus specimens were females and the minimum-maximum and average length values in adult and larval parasites were, respectively, 1.5-2.5 cm (1.99 ± 0.31) and 0.7-1.3 cm (1.025 ± 2.40). Consequently, the species A. crassus, a swim bladder parasite, was found in European eels from the locality Çamalti Tuzla in two seasons (winter and spring) and this parasitic nematode were only in male eels. This study is a first and remarkable one having evidential value, which shows the presence of the species A. crassus among the eel population in the locality Çamalti Tuzla of Izmir Bay. Besides, it is a population that should be monitored due to the status of Anguilla anguilla on the IUCN red list.

The experiment was conducted in one of the unheated plastic polyethylene (PE) greenhouses of Ege University- Bayındır Vocational Training School -TURKİYE during the winter-early spring of 2019-2020. The goal of the trial was to evaluate the effects of liquid vermicompost (LVC) on Iceberg (Head salad) and Lolo rosso (Lactuca sativa) lettuce in a floating hydroponic system. Two types of growing pools were used as the growing media, one was made of galvanized steel and the other plastic polyethylene. Both pools were covered with a polyethylene at a height of 1 meter from the ground. Lettuce seedlings were transplanted into pools filled with water and a week later Liquid Vermicompost (LVC) and Hoagland Nutrient Solution (HNS) were added to the growing media according to the treatments. The trial was set up in a Randomized Block Design (RBD) with 3 treatments and 3 replications in both of the lettuce varieties. 1. Application: HNS +LVC; 2. Application (HNS); 3. Application (LVC). Lettuce leaves were harvested 84 days after the LVC and HNS applications and prepared for analysis. In this research, in order to determine the impact of liquid vermicompost on Iceberg and Lolo rosso lettuce varieties total yield, marketable yield, the number of leaves discarded, root length and root weights were determined after harvested plants. In both of the lettuce varieties, results indicated that the highest marketable yields were obtained in the first treatment (HNS+LVC). The highest root length and root weight were also determined in the first treatment. It can be concluded that adding liquid vermicompost (100 ml / 100 L water ratio) to the growing solutions of Iceberg (Head lettuce) and Lolo rosso (Lactuca sativa) lettuce varieties, high performances can be obtained.
