Farmer Perception of Trees in a Semiarid Agroecological Zone Texte intégral
2022
Eniola Ajibola Olowu | Ian Timothy Riley
Trees in upland, semiarid agroecological zones typically require water efficiency due to low rainfall, cold and dry temperatures as in Niğde Province, Central Anatolia, Türkiye. This study quantitatively assessed farmer perception of ecosystem services and production advantage of trees in a semiarid zone. Forty-nine farmers in Niğde Province were surveyed. The survey evaluated two major factors: ecosystem services and production advantage using eleven indicators. The responses were grouped by age, gender, education, district class (rural and urban) and farm settlement (rural and urban) and were analysed by test of association (χ2) at P≤0.05. Most farmers had knowledge of trees in their environment and mainly supported the perspective that trees were important mainly for cultural and provisioning ecosystem services. However, they held the opinion that having trees on their farmer was a production disadvantage in a semiarid agroecological zone. Although there were no gender differences in their perspectives, there were significant difference by age, education, district class and farm settlement. Farmers in this semiarid agroecological zone seemed more interested in trees with evident ecosystem services and production advantage such as improved crop yield, water efficiency, weed and pest management, ease of harvesting as well as reduced overall production cost. By implication, trees with multiple benefits are required if further planting by farmers is to be encouraged for agroecosystem improvement. In addition, tree choice will be based on farmer perception of the benefits of trees for ecosystem services and production advantage and further research to identify and promote trees that benefits the widest range of agroecosystems.

2022
Mustafa Ulaş
Events such as oxidative stress caused by spinal cord injury (SCI) are a serious condition because they negatively affect many organs. Alternative treatment options for this type of injury are quite limited. In this study, we planned to investigate the effect of oxidative damage on the spleen tissue of rats with spinal cord damage and the protective role of valproic acid (VPA) in this damage. Sixteen Wistar albino rats were divided into two equal groups. No treatment was administered to the rats in Group 1 (SCI-(Control), but a single dose of 300 mg/kg intraperitoneally VPA was administered to the rats in Group 2 (SCI-VPA). Superoxide dismutase (SOD) activities, total antioxidant status (TAS) and total oxidant status (TOS) levels were examined as markers of oxidative stress in spleen tissues taken after decapitation of rats. VPA treatment increased the SOD and TAS level but decreased the TOS level, indicating improved oxidative damage and impaired enzymatic antioxidant levels in spleen tissue homogenate damaged by SCI. We have observed that VPA, which has many beneficial properties, has a significant healing effect on spleen tissue affected by SCI-induced oxidative stress.

In this study, the separation of lactic acid from aqueous solutions using trioctylamine (TOA) reactant and environmentally friendly solvents such as sunflower and rice bran oil was investigated, and it was aimed to contribute to the separation of lactic acid by reactive extraction. It is aimed to determine the most suitable reactant / solvent ratios with reactive extraction analyzes. As a result of the studies, the highest efficiency (72,91%) was achieved with the TOA reactant. An increase in yield occurred as a result of using both sunflower oil and rice bran oil (1:1) together. According to the results of the research, it was determined that the addition of TOA to the organic phase increases the extraction efficiency in the recovery of carboxylic acids from aqueous solutions. While the physical extraction yield was 11.85%, the yield increased up to 72,91% in reactive extraction. An increase in yield was observed about 7 times. As a result of the data obtained, it was understood that with the increase in the extractant concentration, the dispersion coefficient (from 0,13 to 2,69) increased, and the loading factor (from 1,79 to 0,69) values decreased. When the organic phase mixtures formed with the extractant and diluent combinations were examined, it was determined that the best results in terms of extraction efficiency were obtained when 3,62 M TOA for lactic acid was used.

Wheat, which is one of the most widely cultivated crops in the world, has great importance in terms of economy. Wheat is one of the basic food sources of human beings, is one of the first cultivated plants. In order to meet the nutritional needs in parallel with the increasing human population, agricultural production needs to be increased. Fertilization is the most important factor in increasing the yield. Innovations in fertilizer technology and improvement of use efficiency are of great importance. In this study, different doses of mineral (0, 15, 20, 40 kg/da DAP and 0, 20, 30, 40 kg/da AS) and organomineral fertilizers (0, 15, 20, 40 kg/da 20: 20: 0 and 0, 20, 30, 40 kg/da 25: 0: 0) were applied with or without microbial encapsulation to wheat (Triticum aestivum L.) plants (Rumeli cv.) in pots. Some of macro and micro plant nutrients were analysed in three different harvest periods from seed sowing to compare the fertility of the applied fertilizers. According to the results of the research, all applications showed significant differences in terms of all examined parameters. Organomineral fertilizers were found to be more effective than mineral fertilizers. It has been observed that microbial encapsulation is effective at varying levels according to changing fertilizer type and dosage.

Due to high cost of importation and inability of wheat to thrive in Nigeria, baked products like chin-chin are costly and out of the reach of common people. Since baked products are convenient snack relished by all, substitution with readily available materials like cassava flour becomes the only available option. Wheat and cassava flours were blended in the ratios of 70:30%, 50: 50% and 30: 70% respectively while 100% wheat and cassava flours served as controls. Deep fat fried chin-chin samples were prepared from the blends. Proximate and functional properties were conducted on the flour blends while proximate composition and acceptability test were on the chin-chin samples. The results revealed that with increase in cassava inclusion levels in the composite flour blends, there was increase in moisture (7.77-8.23%), carbohydrate (73.42-79.23%), ash (0.75-1.00%), bulk density (0.51-0.61 g/ml), swelling index (0.96.1.09%), water absorption capacity (1.10-1.88 g/g), and emulsion capacity (27.41-39.48%) while dry matter (91.20-9.84%), protein (8.55-6.55%), fat (2.08-0.98%), fibre (2.53-2.20%) and oil absorption capacity (1.29-1.16 g/g) decreased. For chin- chin, there was significant increase in moisture (8.29-10.40%) and carbohydrate (63.63-66.54%) while dry matter (91.70-89.59%), protein (6.66-3.50 %), fat (17.57-16.84%), ash (1.88-1.38) and fiber (1.96-1.69%) decreased. There was no significant difference in the overall acceptability of the chin-chin samples. Therefore, cassava flour substitution of up to 70% is acceptable, but with decrease in most of the nutrient composition which can be improved with lower (

Cattle manure (CM) is mostly used as an inoculum in order to start-up of agricultural biogas plants or as a co-substrate in the anaerobic digestion of lignocellulosic content. Rumen fluid microbiota is also considered to be effective in lignocellulose digestion. It is known that microorganisms in the ruminal waste facilitate the hydrolysis of lignocellulosic structures. However, there are few studies on the inoculum effect of rumen microorganisms on bioreactor performances when rumen content is used as co-substrate and inoculum together with cattle manure, and it is not clear how rumen waste can be used in various anaerobic digestion systems. In this study, biogas production efficiencies obtained from lignocellulosic content in mono and cosubstrate (1:1 and 1:2 Volatile Solids) bioreactors formed by using ruminal waste (RW) and CM microbial communities were investigated. In order to determine the biogas production efficiencies, biomethane potential (BMP) experiments that simulate anaerobic digestion process conditions in a laboratory environment were applied. Treatment with 50% application of RW cosubstrate, 65.51% biogas and 70.64% methane production efficiency increases were achieved compared to monosubstrate CM bioreactor.

This study was designed to investigate the therapeutic effects of Vitis vinifera L. seed extract (5 ppm and 10 ppm) on gill and liver tissues histopathology of carp (Cyprinus carpio L. 1758) exposed to cadmium chloride (CdCl2=Cd) (20 ppb) acute and subchronic period. A total of 140 fish in 14 groups were used in the experiment. The experiment was designed as in two different periods (acute and chronic) and 7 different dose groups (control, vehicle, V. vinifera seed extract 5 ppm, V. vinifera seed extract 10 ppm, Cd 20 ppb, V. vinifera seed extract 5ppm + Cd 20 ppb and V. vinifera seed extract 10 ppm + Cd 20 ppb). At the end of the experiment, the gill and liver tissues dissected from the fish were fixed, dehydrated, cleared, and paraffin impregnated. Appropriately sized blocks were prepared from the tissues, sections of 5-7 µm thickness were taken and covered by staining with hematoxylin-eosin. Stained preparations were examined under a light microscope and photographed. It was determined that all dose groups in the acute period and control groups were not different histopathological. It was determined that the histopathological damage caused by the cadmium group in the subchronic period and tissue damage were reduced in the dose groups with cadmium added with V. vinifera seed extract. As a result of the study, it was concluded that V. vinifera seed extract could have a therapeutic effect on the gill and liver tissues of carp exposed to cadmium.
