2024
Shambel Kiros Simone | Solomon Tiruneh | Abto Asres | Demlie Chanie | Belay Deribe
A survey was conducted in three selected kebeles of Kombolcha Regiopolitan City in South Wollo Zone. The selected kebeles were in proximity to brewery factory, Ethiopia. A semi-structured questionnaire was used to collect perception data from purposively selected three kebeles and a total of 57 randomly selected dairy farmers. Data collected were analyzed with a statistical package for social sciences (Version 20) and Microsoft Excel (2010). Smallholder dairy farmers had average herd size of 10.7 and 0.08 hectare total dairy farm per household. Average daily milk yield and lactation length of dairy cows was 10.8 liter/day and 9.5 months, respectively. The majority of farmers (59.6%) reared dairy cows with 50-75% exotic blood. The most smallholder dairy farmers satisfied their feed demand from the market and had a trend of providing both dense and poor quality affordable feed ingredients. Smallholder dairy farmers gave priority to feed different kind of cattle in the order of lactating cows, calve, pregnant, heifers and dry cows and used (100%) wet brewery spent grain as a source of dairy feed. Though, there was a brewery by-product supply deficit for half of year. The majority smallholder dairy farmers delivered brewery by-product directly from the brewery factories and followed by wholesalers and retailers. The majority of smallholder dairy farmers (96.4%) stated that the brewery spent grain was fed and stored freshly using different conservation techniques, and the remaining stored in ensiled (1.8%) and dried (1.8%) forms. Smallholder dairy farmers had no brewery spent grain ensiling practice and feeding brewery yeast to dairy animals. Smallholder dairy farmers indicated that high price due to abnormal market chain and shortage of brewery spent grain supply were the major challenges to sustain dairy industry in the study area, and the majority (40.6%) claimed to get swift solutions at high cost and less accessible brewery by-product.

2024
Merve Bozdemir Akçil | Zeki Bayramoğlu
This study examines the problems arising from that the agricultural sector has become a significant employment area for migrant labor due to migrant migration. The presence of migrant labor in the agricultural sector has increased because of the cost advantages provided by agricultural operators of cheap labor supply despite informal working conditions. Migrant labor has crucial contributions to the sustainability of production activities, especially in the agricultural sector, where the local labor does not want to be employed. However, the perspective of local people toward migrants differs over time, especially due to different social and cultural characteristics. Since these differences are more noticeable in small settlements, such as rural areas people who are migrant to society or national identity become unwanted in the living spaces of local people over course of time, this study aimed to determine the perspective toward migrant labor and to evaluate the impact of this situation on the sustainability of production. In line with the results obtained, policy recommendations were made for the integration of migrant labor and the planning of agricultural activities.

Uğur Tan
The utilization of Nigella sativa L., commonly known as black cumin, in traditional and medicinal practices is well-documented, attributing to its wide-ranging biological activities. Given its significance, this study explores the efficacy of various seed priming treatments (control, distilled water, potassium humate, and gibberellic acid) under laboratory and field conditions to enhance the early growth stages of Nigella sativa L. Priming treatments aimed to improve germination rates, plant height, and other growth parameters, potentially translating into increased agricultural productivity. According to results plant height ranged from 52.38 to 58.91 cm, number of branches between 3.76 and 3.98 (branch plant-1). The number of capsules varied from 4.93 to 6.81 (capsule plant-1), capsule seed weight was between 0.19 and 0.22 (gram capsule-1 ), and the thousand-seed weight ranged from 2.26 to 2.39 grams. The germination rate ranged from 78% to 93%, germination index 4.22-5.83 and mean germination time was observed from 4.27 to 4.82 days. Our findings reveal significant effects of priming on germination parameters and plant height, this offering insights into the potential of these treatments to optimize crop growth. However, the transition of these benefits to field conditions, particularly yield-related parameters, appeared limited, suggesting the complex nature of growth enhancement strategies and their implications for agricultural practices.

Potatoes for use in industrial processing must have a low reducing sugar concentration. This study investigates the impact of organic and synthetic fertilizers on the composition of Irish potato cultivars’ reducing sugar, specific gravity, dry matter, and starch. The research was conducted at Busogo Farm in Rwanda, using randomized complete block designs in seasons 2021 B and 2022 A with rate of ten tones per hectare under the doses of 100%, 50%, and 0% and three hundred kilograms per hector under the dose of 100%, 50% and 0% respectively for farmyard manure and NPK 17.17.17. Results showed significant effects of season and treatment on reducing sugar levels in potatoes. Twihaze and Kirundo varieties recorded high glucose (0.09%), while Gisubizo variety in control, recorded low glucose (0.01%). Additionally, the analysis of variance showed that Irish potato varieties with low to moderate and moderate to high glucose contents, respectively, experienced extremely significant (p 0.001) effects of farmyard manure and NPK on glucose content for the seasons 2021 B and 2022 A. The application of inorganic and organic fertilizers had a significant impact (p 0.05) on dry matter in seasons B and A, according to the analysis of variance. Additionally, the results demonstrated extremely significant (p<0.01) differences in specific gravity and starch in both seasons, with Kinigi variety having higher values of dry matter, specific gravity, and starch content in season B and A, respectively, of 24.58, 1.10, and 18.59%. Season 2022 A’s high decreasing sugar levels were caused by meteorological conditions brought on by the soil’s high moisture content as well as the maturity of the tubers. Due to its low level of reducing sugar, Gikungu, Kirundo, and Kinigi are excellent for chips whereas Twihaze variety is advised for boiling cooking methods.

In this study, it was to identify a method for separating the free bulgur bran from the fine bulgur during the production of bulgur. This was attempted by creating an electrostatic field using a PVC surface. It was observed that the issue of free bran, which adversely affects the packaged products visually, was effectively solved by this method. In contrast to conventional techniques, an alternative methodology was employed which utilizing a device comprising a folded PVC surface (folded curved channel). The configuration of the experimental apparatus was developed with dimensions of 4, 5 and 6 cm in width, 20, 40 and 60 cm in length, and angles of 30, 35 and 40 degrees, respectively. At the end of the PVC surface, plates were placed to create an electric field. In order to create the electric field, one of the plates was charged with a positive and the other with a negative charge. The distance between the plates was varied according to the width of the tunnel. The expected results were obtained in the layered PVC system. Consequently, a fine bulgur mixture consisting of 5 g of bran per 1000 g of bulgur was introduced into the experimental system at a flow rate of 0.89 g/s. This resulted in a notable reduction in the free bran content, which decreased from 5 g to approximately 2 g.

Beril Kocaman
Strawberry (Fragaria × ananassa Duch.) is one of the most widely consumed and cultivated fruits worldwide. Sorbitol plays a role in plant responses to many biotic and abiotic stresses. In this research, we intended to understand the effect of sorbitol spraying on the bioactive compounds of strawberry leaves. The application of sorbitol at different concentrations (0, 25, 50 mM and 75 mM) greatly improved strawberry characteristics such as total chlorophyll, chlorophyll a and b, carotenoids, and total phenolics. As sorbitol concentrations increased, chlorophyll a and chlorophyll b values increased in the samples taken during the fruiting period and higher values were obtained. The carotenoid content increased by approximately 189.49% and the total phenolic content increased by 30.85% in strawberry plants treated with sorbitol compared with the control. Supply of sorbitol decreased flavonoid content. The results indicate that sorbitol treatment has no inhibitory influence on the overall growth of strawberries. Among the biochemical parameters analyzed, chlorophyll, phenolic, and carotenoid contents increased, whereas flavonoid content decreased with sorbitol application.

This study was conducted to determine the effect of rearing quails in different rearing systems on egg production, egg quality characteristics, and incubation results. The 360 quails were distributed equally to 3 different rearing groups (cage, enriched cage, and floor) in a male:female mixed at the age of 3 weeks. The eggs were individually weighed and recorded one by one daily (5487 eggs) for 3 months. To determine egg quality and incubation characteristics, 750 eggs were broken, and 3284 eggs were incubated, respectively. The results showed that female quail in the floor group have lower body weight at 6 weeks old (177.19 g), and they reached sexual maturity (age of first egg laying) later (65.36 day, P<0.01), The lowest egg production (61.14%) occurred in the floor group during the 3-month egg production period (P<0.05). The lowest average egg weight (9.07 g) was determined in the floor group (P<0.05). It was determined that the eggs of quails raised in the enriched group had a rounder shape index because they have larger widths (P<0.01). While the highest average yolk height (11.24 mm) was determined in the enriched cage group (P<0.01), the highest averages of albumen length (72.41 mm) and lowest averages of yolk index (48.43%) were determined in the cage group (P<0.01). The lowest average values (113.17) in Haugh unit were detected in the floor group (P<0.05). The highest fertility rate (98.44%) was in Floor♂:Cage♀, the highest hatchability of fertile egg rate (94.67%) was obtained from Enriched♂:Cage♀, and the highest hatchability (89.10%) was obtained from Floor♂:Cage♀ pairing (P<0.05). The lowest fertility rate (88.00%) was obtained from the Enriched♂:Floor♀, the lowest hatchability of fertile egg rate (86.01%) was obtained from the Enriched♂:Enriched♀, and the lowest hatchability (75.62%) was obtained from the Enriched♂: Enriched♀ groups. As a result, it has been revealed that the effect of various rearing systems is different on egg production, egg quality traits, and hatching results in quails. Thus, it has been shown that different programs at the rearing period to be applied to the male and female quails can achieve better incubation results and reproductive success.

The escalating global population, diminishing agricultural lands, and the overarching global climate crisis are significantly impacting pepper cultivation. These challenges exacerbate the vulnerability of pepper plants to various biotic and abiotic factors, particularly viral diseases, resulting in diminished yield and quality. Cucumber mosaic virus (CMV), a notable concern for peppers in the Solanaceae family, is causing substantial quality and yield losses, with no effective chemical control methods currently available. This study focuses on exploring the genetic structure of CMV isolates obtained from pepper production areas in Kilis province and comparing these regions through the High-Resolution Melting (HRM) method. CMV isolates, cultivated in tobacco plants, have their partial coat protein sequences compared with those of other CMV isolates registered in the gene bank. The nucleotide sequences of identified CMV isolates are phylogenetically grouped and compared using an HRM graph. The HRM graph effectively distinguishes Kilis 3 and Kilis 4 isolates, clustered similarly to sequence patterns, from other isolates. The study highlights the utility of HRM analyses in identifying differences between isolates before determining sequence patterns. In the gene bank comparison, Kilis CMV isolates distinguished from others. Similarities were observed with isolates from Iran's Balsam (Impatiens balsamina - LC066478), Türkiye's Radish (Raphanus sativus - LC0665051), and Wild Turnip (Rapistrum rugosum - LC066514, LC066511, LC066517). The study found that Kilis 7 CMV isolate, transferred mechanically to 24 different pepper genotypes (C. annuum) from the local population, revealed susceptibility to CMV in the 24 lines developed from the Elbeyli population in Kilis province.

Ayşenur Kanat | Osman Sabri KESBİÇ
The main goal of this study was to assess the qualitative composition of essential oil (P), a natural extract produced from wasted orange peels in the citrus processing sector. Additionally, the study aimed to investigate the alterations in fish feeds when this essential oil is incorporated and stored. The essential oil was extracted from the orange peels provided for the study using the hydrodistillation method and the Clevenger apparatus. The study determined the volatile components of the oil with 100% accuracy. The primary constituent was identified as D-limonene, comprising 59.27% of the total composition. Subsequently, experimental feed groups were established by including the essential oil in the feed rations at ratios of ‰0 (P0), ‰0.5 (P5), ‰1 (P10), and ‰3 (P30). Under storage conditions, the feeds were stored in feed sacks for 60 days. Periodic samples were collected during storage and subjected to nutritional, microbiological, structural, and oxidation tests. The results of the study show that P had no protective effect in fish diets against the growth of yeasts, molds, and other mesophilic aerobic bacteria (p > 0.05). It was shown that the nutritional values varied over time during storage. However, this variation was not substantially correlated with the amount of P in the diets (p > 0.05). There was no discernible impact of the addition of P on the structural characteristics of the feed grains. Nevertheless, the inclusion of P substantially impeded the process of lipid oxidation in the diet (p<0.05). After the two-month storage period, it was shown that adding at least 1 ‰ of P to the fish meals prevented the peroxide generated from oxidation in the feed from exceeding acceptable levels.
