Determination of Energy Use and Greenhouse Gas Emission in Individual Deep Well Irrigation Enterprise Полный текст
2022
Abdurrahman Yusuf Halkacı | Ramazan Toprak
This study was conducted to determine the annual energy use and related greenhouse gas (GHG) emissions of individual deep well irrigation enterprise. That study was conducted at deep well farm belonging to one farmer with volunteer preforming farming activities in Konya-Meram-Çarıklar location for the growing season of 2021. In that regard, the activities using alfalfa and dry bean production, and total production inputs with their amounts as well as crop yields were determined separately. By considering unit energy equivalent values and GHG emission factors of each input, annual energy consumption and GHG emission values were calculated. Similarly, by examining energy content and crop yield in accordance of crop production unit (kg), annual produced energy amount was calculated. The evaluation was made using energy used and energy produced as well as GHG emission values indicators at individual deep well irrigation farm. According to the results obtained, annual energy use and energy production were calculated 253035 mega-joule (MJ), and 487960 MJ, respectively for individual well irrigation farm. The electricity used during the irrigation processes resulted around 71% of annual energy consumption. The annual GHG emission amount as an equivalent to the carbon dioxide (CO2eqv) for research farm with GWI was determined as 18575 kg (18575 kgCO2eqv year-1). Almost 52% of annual GHG emission was resulted from electricity used in irrigation.

Harun Kutay | Hasan Rüştü Kutlu
In this study orange pulp, dried in hot air, was replaced at control, 7.5, 15 and 22.5% levels (DM basis) with ground corn in the concentrate feeds of dairy goats. Considering the milk yield, average live weight and age of the animals, a total of 24 animals were used in 4 groups with 6 animals in each. Goats with 1375±330 ml milk yield, 2.45±0.17 years of age and 55.40±0.91 kg body weight were chosen for the trial. The animals were housed in individual compartments of 2x2 m during the study. In 2 weeks of adaptation, 8 weeks data collection of the trial, feed and water were provided ad libitum. Orange pulp utilisation increased dry matter intake, did not change milk yield and feed conversion rates, and negatively affected the body weight changes. Somatic cell counts were found to be lower in the control group in the middle of the study. Blood glucose and cholesterol levels were reduced, NEFA and BHB increased due to the treatments.

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.

Texture classes of soil samples of the research area was; loam, clay loam and sandy clay timbre, 55% loam, 40% clay timbre and 5% sandy clay. The pH of the soils varies between 6.50-7.57, with an average of 7.14 neutral and CEC values between 17.3-29.5 cmol/kg. Lime content is 3.95-12.10%, mean of 7.11%; 30% are limy and 70% are medium limy, organic matter contents are 1.20-2.59%, average of 2%, 45% organic matter is considered low and 55% is medium. Their EC was between 0.14 and 0.43 dS/m, with an average of 0.21 dS/m; there is no salinity problem in the soils. Total N contents were 0.03-0.10%; 15% is very little, 65% is insufficient and 20% is sufficient, plant-friendly P, between 5.67-11.7 mg/kg; 20% is insufficient and 80% is sufficient; K content was 1.09-1.77 cmol/kg, an average of 1.45 cmol/kg is sufficient and excessive. The interchangeable Ca 7.90-9.90 cmol/kg is sufficient, with an average of 8.82 cmol/kg. Changeable Na, 0.87-1.56 cmol/kg, average 1.20 cmol/kg, normal level; plant Fe is sufficient in 12 of the 2.78 mg/kg to 6.90 mg/kg, 60% of the soils are sufficient and 40% are insufficient; Cu, available zinc (Zn) contents 0.29 to 0.78 mg/kg; 10% are sufficient and 90% have insufficient available Zn content; the available Mn level was insufficient in all soil samples. As a result, it was determined that at least half of the research area soils are in dire need of increasing the organic matter content, nitrogen fertilizer, partially phosphorus fertilizer and especially microelement fertilizers such as Zn and Mn. Therefore, it is recommended to eliminate the deficiencies with macro and micro elements in leaf or organo-mineral (micro-element-containing) fertilizers in light of economic and ecological planning by conducting correlation and calibration studies with plant response.

The detection of weeds with computer vision without the help of an expert is important for scientific studies and other purposes. The images used for the detection of weeds are recorded under controlled conditions and used in image processing-deep learning methods. In this study, the images of 3-4-leaf (true-leaf) periods of the wild mustard (Sinapis arvensis) plant, which is the critical process for chemical control, were recorded from its natural environment by a drone. The datasets were included 50-100-250-500 and 1 000 raw images and were augmented by image preprocessing methods. Totally 12 different augmentation methods used and datasets were examined for understand how to affects the numbers of images on training-validation performance. YOLOv5 was used as a deep learning method and results of the datasets were evaluated with the Confusion Matrix, Metrics-Precision, and Train-Object Loss. For results of Confusion Matrix where 1 000 images gave the highest results with TP (True Positive) 80% and FP (False Positive) 20%. The TP-FP ratios of 500, 250, 100 and 50 image numbers were respectively; 65%-35%, 43%-57%, 0%-100% and 0%-100%. With 100 and 50 images, the system did not show any TP success. The highest metrics-precision ratio was found 92.52% for 1 000 images set and for 500 and 250 image sets respectively; 88.34% and 79.87%. The 100 and 50 images datasets did not show any metrics-precision ratio. The minimum object loss ratio was 5% at 50th epochs in the 100 images dataset. This dataset was followed by other 50, 250, 500, and 1 000 images respectively; 5.4%, 6.14%, 6.16%, and 8.07%.

2022
Emrah Karadağ | Aylin Ağma Okur
Feed costs are of great importance for an economically and ecologically sustainable livestock, as they constitute approximately 60-70% of the costs in animal husbandry. As in the whole world, price increases were observed in feed raw materials depending on the supply-demand balance and pandemic conditions in our country, and this situation was also reflected in feed prices. For example, when the prices of broiler and egg feeds were analyzed between January and November 2021, an increase of 59.7% and 62.6% was observed, respectively. Feed mixes are prepared and fed in order to meet the daily nutritional needs of animals in an optimum way and at minimum cost. In order to meet this need, the research of alternative feed raw materials and their use in rations have been researched for many years. With this study, it was aimed to determine the nutritional composition of the processing by-products (rice broken, bean broken, chickpea broken, lentil broken, lentil bran, corn mix, bulgur bran, sub-semolina by-products) of food production factories and to reveal the possibilities of their use as alternative feed raw materials in animal nutrition. In addition, up-to-date data on the feed industry in Turkey were presented, and the importance of the orientation to alternative feed raw materials in terms of economy, product diversity and sustainability in Turkey and in the world was emphasized. Crude cellulose (HS) ratio of lentil bran, which is one of the under-sieve products, was found to be the highest numerically with 20.6%, followed by bulgur bran (12.7%). However, NDF and ADF contents were also found to be numerically high. Crude protein values were found to be the highest numerically in legume products (21.83%), beans (20.58%) and lentils (24.15%) among the processed residues. In addition, it will be useful to determine the usage rates in the ration, taking into account the anti-nutritional properties of each product.

2022
Uche Anyaiwe | Mattew Oluwamukomi | Taiwo Aderinola | Tayo Fagbemi
‘Lafun” was enriched with soy protein supplements (curd or residue) during the mashing before drying at 10%. The amino acid result indicated that enrichment improved the amino acids contents as well as the protein quality of the products. While enrichment generally improved the mineral element composition, enrichment with the residue significantly improved the mineral composition when compared to enrichment curd. That the products were hygienically produced was confirmed by the non-detection of heavy metals which may suggest it safety for human consumption. Condensed tannins, phytate, oxalate, hydrogen cyanide and trypsin inhibitor were tested as possible anti-nutritional factors in the product and the values obtained were within safe level and correlated with those reported in previous or similar studies. It was concluded that enrichment with soy curd/residue is a safe and viable means to improve the nutritional benefits derivable from “Lafun” especially for those that ‘Lafun” is a major staple.

Gülten Tiryaki Gündüz | Burcu Sıla Göral
Grape pickle is a traditional food that is made with grapes (Vitis vinifera), horseradish (Armoracia rusticana) and grape syrup. In this study, the survival of Bacillus cereus and Escherichia coli in grape pickles produced with or without using probiotic Lactobacillus acidophilus La-5 as well as microbiological, chemical and sensory properties of each group were examined during 35 days of ripening at 25°C and 5 months at refrigerated storage period. Molds and lactic acid bacteria (LAB) counts remained below the limit of detection (6 log in samples to be considered a probiotic product. E. coli counts rapidly declined to undetectable level within 7 days, while B. cereus numbers was found 1.56-1.72 log cfu/g at the end of the storage period. As a result, it was established that traditional grape pickle is not suitable food matrix for probiotication. High total soluble solid content (63 °Brix) and presence of horseradish in grape pickles ensure the microbiological stability as well as the safety of product.

Over recent years, the demand for livestock products in Ethiopia is increasing; most of this demand is coming from urban centers, especially from Addis Ababa, as the buyers are demanding better quality and more hygienic produce. This has fueled interest in better quality animal feed, mainly from larger-scale commercial livestock producers. With this background, there has been interest in stimulating plant-based protein production that can be incorporated into livestock feed. Small quantities of lupins are grown (less than 20,000 ton per year) in the North Western part of Ethiopia for human consumption. These lupins are bitter due to their alkaloid concentration and are unsuitable for livestock feed. If non-bitter (sweet) varieties are grown, then they could be a source of protein for animals as is the case in some countries, such as Australia. The Ethiopian market for livestock feed was surveyed and segmented to evaluate the opportunities for lupins. The survey revealed that the livestock sector in Ethiopia is suffering from feed shortage both in terms of quality and quantity. Lupin, as a potential protein source feed has an opportunity to be incorporated into the livestock feed industry. Currently it is estimated that if sweet lupins were available, the short-term demand from commercial livestock producers and feed processors market segment is 20,000 t/year. In the medium-term, it is expected that as the national poultry production expands, there will be an increased demand from the large feed mill factories to around 35,000 to 40,000 t/year grain for high quality protein such as lupin. It is recommended that the already started sweet lupin promotion in the country has to be done at scale. In addition, production of sweet lupin in Ethiopia should be focused on the commercial farming sector and the marketing should be through the large-scale processors or direct to large-scale livestock producers.

Emine Açar | Yıldız Aka Kaçar
The Myrtle plant (Myrtus communis L.) is a plant species of the Myrtaceae family and a member of the maquis community, which naturally spreads in Mediterranean regions. Being resistant to arid conditions, the ecological distribution areas of the myrtle plant have been allowed to expand. The myrtle plant has been used of medicinal and aromatic plants, having interesting and beautiful flowers, and rich nutrient content of the fruit in terms of valuable phytochemicals, in particular, the nutritional content of its fruits and valuable metabolites have allowed the myrtle plant to be among the healthier foods. Antioxidant activity, which neutralizes reactive oxygen species (ROS), which causes many medical problems, is one of the most important features of the myrtle plant. Investigation of the biosynthesis of anthocyanin, which leads to antioxidant activity, and determination of the biosynthesis in different tissues and genotypes is important, especially in the development of production activities. Furthermore, this study aimed to investigate the anthocyanin biosynthesis in different genotypes with white and black fruits and various tissues of genotypes. For this purpose, the expression levels of CHS, CHI, F3H and PAL genes, which are involved in the anthocyanin biosynthesis pathway, were determined by qRT-PCR. In the study, it was determined that there was an increase in the level of genes related to the biosynthesis of anthocyanin in the leaf and fruit tissues of the genotype with white fruits. It was determined that the expression level of genes related to the biosynthesis of anthocyanin was observed to be higher in the leaf and fruit tissues of the genotype with black fruits, and the highest gene expression level was found in black fruits. It was observed that anthocyanin biosynthesis was synthesized in different tissues of the plant, and anthocyanin biosynthesis was higher in fruits compared to leaves.
