2022
Joy Chiamaka Echebiri | Gabriel Oladele Awe
Land use could impact soil properties and processes in varying degrees. Therefore, the impact of different land use systems on soil water status and its relationship with some physiochemical properties was studied at the Teaching and Research Farm, Ekiti State University, Ado Ekiti, Nigeria. The land use types included native forest (NF); Paddock (P); Oil palm plantation (OP); Teak (TK); new yam plot (NY) and yam plot under fallow (YF). Structure and disturbed surface soils (0 - 15 cm) samples were taken at three (3) locations in each land use type. Soil water content (SWC) significantly varied among the different land use types, with oil palm plantation storing the highest amount of water. The results also showed significant differences in soil bulk density, organic carbon, porosity, texture and hydraulic conductivity among the land use types. SWC associated positively and significantly with organic matter, silt content and silt + clay. The association between SWC and pH and silt/clay were positive but weak while particle density, bulk density and sand content showed negative and significant association. The principal component regression (PCR) showed a highly significant, positive relationship between SWC and the principal components of other physicochemical properties. Cluster analysis showed that SWC is highly related and linked to OM, Bd, Pd, Pt and silt/clay. The results implied that conversion to paddock and continuous cultivation led to depletion in soil water, physical and chemical properties, whereas cultivation of tree crops conserved these soil properties better. Therefore, establishment of tree crop and conservative soil management practices are suggested to prevent agricultural lands from degradation in areas with soils under similar conditions.

Seyfullah Cengiz | Murat Reis Akkaya | Osman Kola
Peanut allergens adversely affect the health and quality of life of millions of consumers worldwide. The seeds of the peanut plant (Arachis hypogaea L.) contain a number of allergens that trigger the production of specific IgE antibodies in allergy-prone individuals. Currently, 18 proteins found in peanuts are accepted as allergens. These allergens are named from Ara h 1 to Ara h 18. Ara h 2, Ara h 6 and Ara h 7 are from albumin, Ara h 1 and Ara h 3 are from globülin. Ara h is the abbreviation of Arachis hypogaea, the Latin name for peanut. A peanut allergy is a reaction that occurs shortly after eating to peanuts or peanut products. It has various symptoms that can go up to swelling of the tongue, itching of the palate, itching and burning in the throat, itching in the eyes and nose, nausea, vomiting, abdominal pain, shortness of breath, wheezing, bruising, chest pain, hives, low blood pressure and shock. In this review, the properties of peanut allergens and the methods of reducing the allergen effect will be reviewed.

The effect of antifreeze protein type III (AFPIII) and human heat shock protein 70 (HHSP70), added to the vitrification medium of mouse embryos, on post-freeze/thaw in vitro embryonic growth rates and cell numbers were investigated. In total 20 female mice were synchronized. After synchronization, 2 females and 1 male were mated in the same cage. Twenty-four h after mating, the embryos were collected at the pronuclear stage. In total 8 groups were established, including a positive control group (C+), a negative control group (C-), and treatment groups that were vitrified in a medium added with 200, 400 and 800 ng/ml of AFPIII (AFPIII200, AFPIII400, AFPIII800), and 1, 2 and 4 µg/ml of HHSP70 (HHSP70-1, HHSP70-2, HHSP70-4). Solid surface vitrification (SSV) medium was prepared for the vitrification of the embryos. Once thawed, in vitro development rates of embryos were followed at 24, 48, 72 and 96 h. Four embryos, which progressed to the full blastocyst stage, were taken from each group and stained with the Hoeschst 33258 and propidium iodine (PI) dyes to determine the inner cell mass (ICM), trophectoderm (TE) and total cell numbers. The groups showed statistically significant difference for in vitro embryonic development rates at 48, 72 and 96 h (p

The identification of plants in which the bees forage is key in establishing bee farms and increasing honey production. In this study pollen analysis of honey samples from the southeastern part of Nigeria was carried out to ascertain their floral sources and ecological origin. The honey samples were acetolyzed and microscopically studied to determine the pollen types. A total of seventy-one pollen types belonging to forty-one families of plants were identified. The honey samples were dominated by pollen grains from the families of Arecaceae, Euphorbiaceae, Myrtaceae, Irvigiaceae, Fabaceae, Combretaceae/Melastomataceae, and phyllanthaceae. Some of the dominant pollen grain identified include Elaeis guineensis, Alchornea cordifolia, Hymenocardia acida, Ocimum gratissimum, Syzygium guineense, Nauclea latifolia and Afzelia africana. Out of the six samples studied Njikoka sample was monofloral having Mimosa pigra as predominant pollen while Ayamelum, Ekwusigo, Nsukka, Ezeagu, and Udenu samples are multifloral containing Elaeis guineensis, Phyllanthus sp., Piliostigma reticulatum, Irvingia sp., Alchornea cordifolia, and Lannea sp. as major secondary pollen. All the samples analyzed have Elaeis guineensis in common except Ezeagu, indicating that these plants are present in all five locations. These results can also be used as a tool in the geographical identification of Southeastern Nigeria honey from other geopolitical zones.

Kani Yavuz
Crop and animal production constitute a large part of the people's livelihoods in Bayburt province. In addition, the province has become one of the important animal husbandry centers of the region due to the fact that it is a transit point between the Eastern Anatolia region and the Black Sea region. But the number of small farms in Bayburt province is still very large, and the number of farms that are members of grower organizations is quite small. In addition, the migration of the young population from villages leads to an increase in the average age of the population engaged in animal husbandry and a decrease in the number of animals that can be raised depending on the labor force. In this review, the general status of cattle and small ruminants livestock in Bayburt province was given and the level of livestock in Bayburt province was revealed with current data.

Effects of Forage Legumes Sowing in the Fallow Year on Silage Yield and Quality Characteristics of Subsequent Cereals النص الكامل
2022
Musa Saylan | Süleyman Avcı
In this study, the effect of P. arvense-H. vulgare mixture and V. pannonica grown in the fallow year on silage yield and quality of subsequent cereals were investigated in the arid condition of Eskişehir, Turkey. The fresh weight of P. arvense-H. vulgare mixture with 2750 kg/da was found two-fold high than V. pannonica. P. arvense-H. vulgare mixture significantly increased the fresh and dry hay weights of cereals except for H. vulgare cv. İnce. In addition, the highest grain yield was obtained by growing Triticosecale cv. Karma in P. arvense-H. vulgare mixture plots. Due to the high pH and low dry matter content of triticale samples, the Fleig scores were very low, which is a quality indicator in silage. ADF and NDF ratios were the highest in A. sativa cv. Checato as a negative quality factor. Top-dressing of nitrogen had a positive effect on the crude protein ratio. It was concluded that production of quality roughage can be sustainably increased by growing P. arvense-H. vulgare mixture in barren areas in the fallow year and followed by sowed cvs. Karma, Müfitbey, and Checato in the cereal growing season.

This study was performed to investigate how to smoke solution affects dry matter loss, crude protein (CP) and toxic compound ODAP contents of grass pea in hydroponic media during seven days period. Three doses of smoke solutions (1, 5 and 10%, V: V) by diluting with tap water were applied to seeds as priming agent, and tap water was used as a control (0%). The experiment was arranged according to the split-plot design with three replications. Compared to seed, significant change was detected in hydroponic sprouts depending on the day in terms of dry matter loss and chemical content. Grass pea sprouts had higher CP and lower ODAP content than seed, even in control treatment. Furthermore, smoke solution increased the efficiency of system by increase CP, decrease ODAP content and also decreases dry matter loss, with significant effect on doses. CP of sprouts increased day by day and was the highest on day 6 (36.27%) at the 10% dose of smoke solution followed by 5% on day 7 (36.09%). ODAP decreased up to day 6 and then began to increase, but it was lower than control at all doses of solution during to experiment. This study showed that grass pea is suitable crop for hydroponic forage produce and that smoke solution can make a significant contribution to yield and quality of sprouts, especially at the dose of 10%. However, when the yield, nutritional value, and safe use were evaluated together, it was observed that the best time for harvesting was the end of the 6th day and delaying did not provide a significant advantage and even occurred undesirable results in terms of ODAP and dry matter.

In this study, alkali dietary fiber extraction method was evaluated to obtain soluble and insoluble dietary fiber from Trigonella-foenum graecum L. (fenugreek) seeds. The process conditions of alkali extraction method ensuring the highest total dietary fiber yield were investigated by response surface methodology. Furthermore, some physicochemical and functional properties of extracted soluble and insoluble dietary fiber from fenugreek seeds such as water retention capacity, oil adsorption capacity, swelling capacity, glucose adsorption index and α-amylase inhibition capacity were determined. Total dietary fiber yield was 78% at 52.50 g/L of sample: NaOH ratio and 1.01 M NaOH concentration as the optimum process conditions. Furthermore, insoluble dietary fiber gave better results than soluble dietary fiber when physicochemical and functional properties were compared.
اظهر المزيد [+] اقل [-]Barriers to Climate Change Adaptation of Wheat Producing Farmers; the Case of Çorum Province-Türkiye النص الكامل
2022
Güngör Karakaş
Global climate change, the effect of which has been increasingly felt in the last ten years, has made itself felt more in many regions in Turkey, especially in 2020 and 2021, and a serious temperature increase, floods and forest fires have been seen. Climate change affects the most vulnerable agricultural production. Since the adaptation of farmers to climate change is important in terms of food prices and sustainability of agricultural production, it is important to identify the barriers to adaptation of farmers to climate change. The aim of this research is to investigate the barriers to the adaptation to climate change of wheat producing farmers in Çorum province, where wheat is produced on 37% of the total agricultural land. In order to achieve this aim, 424 farmers were interviewed and their climate change 'understanding', 'perceptions', 'attitudes' and climate change adaptation 'barriers' were examined. As a result of the research, it has been determined that the farmers perceive climate change as "drying of water resources" and “increase in drought”, and they have an attitude that "we should strive together to adapt to the changing climate" rather than an individual struggle. In addition to these, it has been determined that “climate change is perceived as a serious problem” by the farmers and as a result of all these, the lack of “access to water resources” is the most important obstacle in adapting to climate change. In order to accelerate the adaptation of farmers to climate change, to protect them against the negative effects of climate change and to make local adaptation strategic plans, politicians, non-governmental organizations, public, private sector, universities, national and international organizations have important duties.
