Farmer Perception of Trees in a Semiarid Agroecological Zone 全文
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.

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.

Field experiments were conducted in 2018 and 2019 at the National Potato Research Programme (NPRP), Lalitpur (1360 masl), Nepal, to determine the effect of crop geometry on the growth, yield, and quality of sweet potato genotypes. The experiment was laid out on sandy loam soil in a factorial randomized complete block design (RCBD) with three replications and comprised of a total of twelve treatment combinations of four crop geometry (60cm×25 cm, 60cm×30 cm, 70cm×25 cm, and 70cm×30 cm) and three genotypes (CIP 440015, CIP 440267 and Local White). Among the different crop geometries and genotypes evaluated, 70cm×30 cm plant spacing and Local White genotype were found statistically superior to enhance marketable tuberous root weight per plant (0.572 and 0.541 kg), tuberous root diameter (62.59 and 61.0 mm), shoot fresh weight (509 and 524 g), and tuberous root yield per plant (616 and 620 g). The genotype, Local White yielded higher among the genotypes. The reducing sugar content was influenced significantly by crop geometry and genotypes. The pooled mean showed the highest (15.48 and 17.26 %) reducing sugar in closer geometry 60 cm × 25 cm and Local White genotype respectively and the lowest (11.54 %) in the genotype CIP 440015. CIP genotypes, on the other hand, were high in ß carotene content, whereas the Local genotype had a negligible amount (0.35 mg/100g). On hectare level, our result showed that highest plant density of 66,666 plants ha-1 (60 cm × 25 cm) could give the highest yield per unit area due to greater crop biomass. Our findings suggest that crop geometry can have a considerable impact on sweet potato production. As a result, the geometry of sweet potatoes can be wide or narrow depending on our needs and the area available in our study area or a similar situation.

Nouara Boulfoul | Fatima Brabez
The key objective of this research review is to elucidate the mechanisms for applying a food safety scheme based on the Hazard Analysis and Critical Control Points (HACCP) system and to identify the difficulties and benefits of this technique (HACCP) in Algeria. Characterization of food processing companies around the capital of Algeria was carried out on the basis of questionnaires and direct interviews with the manager in charge of these companies. Forty-six agri-food firms working in the Algiers region and operating in the field for more than 15 years (80.5%) with Joint Stock company (JSC) status (23.9%), Limited Liability Company (LLC) (63%) and multinational companies (26.1%). The establishment of a transparent and effective framework for food safety controls will enable compliance with customer requirements, improved product quality and a stronger commitment to food safety managers. This is favorably correlated with the age as well as the level of education of the managers of the different surveyed companies. The survey conducted in the Algerian region showed that the key barriers to the introduction of the food safety management system (FSMS) in general are inadequate knowledge and competence of the HACCP and a long time to be developed FSMS, a lack of expertise and technical support and a lack of specialized expertise, intelligence and technological assistance to help the small and medium-sized enterprises (SME). The findings of the survey also revealed that the key reason for the introduction of the FSMS is to strengthen product protection, recognize the strengths and shortcomings of the business, enhance relationships with suppliers and enhance government and consumer confidence.
