2022
Eda Adal | Tuğba Aktar
Pomegranate (Punica granatum L.) is a fruit that grows in most tropical and subtropical regions. It has 52% aril, consisting of 78% juice which is used as; juice, molasses, jam, wine, and dried kernels. Potential health benefits increase the demand for the fruit as well as its products. Pomegranate seeds, which consist of approximately 10% of the whole fruit, are a by-product of the juice and juice using products containing nutraceutical functional components such as sterols and punicic acid. Pomegranate seed oil is considered a healthy alternative source of oils, and its production is a valorization process since it is the by-product that usually goes to waste. In the present study, pomegranate seeds were used for oil extraction using the cold solvent extraction method. Oil samples were then taken to the Schaal oven treatment in order to determine changes due to storage. Oil samples were tested for 14 days of total storage at their 1st,3rd, 7th, and 14th days for the oxidation tests, colour, fatty acid composition, and Fourier transform infrared spectra analysis. Data were tested for significance by using statistical analysis. The results indicated that oxidative stability of pomegranate seed oil was decreased by increasing storage time. The studied techniques used in this paper can be valuable processors to monitor the oxidative stability of oils with storage time and evaluate their acceptance on the market.

This study was carried out in the central county of Ağrı Province in order to reveal the cattle feeding habits of cattle breeders. For this purpose, data were obtained by conducting a face-to-face survey with 400 dairy cattle owners of the enterprises in the county. According to the results obtained from this study, it was determined that 91.5% of the breeders produced their forage crops. It was also found out that barley, alfalfa, and sainfoin were the most produced plants in these enterprises. However, the production of the corn silage, which is an important source of roughage for dairy cattle, was performed at a very low level (1.2%). Dry hay (93.5%) took first place among the roughage sources used in these enterprises, and it was followed by alfalfa hay (61.5%) and wheat-barley straw (28.0%). Corn silage was used at a low level (7.8%) in the cattle enterprises. It was determined that cattle breeders in the central county of Ağrı province were deficient in terms of some information about cattle feeding practices. It was also demonstrated that it was necessary to increase the usage and production of corn silage as forage crops and to implement rational animal feeding practices in place of the old traditional animal feeding habits. Therefore, cattle breeders in the central county of Ağrı province should be involved in technical training programs about the cattle feeding and forage planting. As result of the courses given to the cattle breeders, their technical information about cattle nutrition and preparation of ration would be updated. For this purpose, it is also recommended that agricultural extension service should be boosted to increase the education level and awareness of the cattle breeders in the rural areas.

Rosehip fruit, which is widely and naturally grown in many European countries as well as in Rosehip fruit, which is widely used in Turkey as well as in European countries and grows naturally, is a very rich species in terms of vitamin C value. Due to its benefits to human health, its consumption is increasing and its use in different forms is becoming widespread. In this study, the colour, effective diffusion-activation energy, phytochemical properties and thin-layer drying patterns of rosehip fruit of the ‘Yıldız’ variety were investigated after drying in a convective dryer at different temperatures (40, 50, 60 and 70°C). In the study, it was determined that 70°C temperature was statistically more suitable in terms of measured and calculated colour values. It has been determined that the effective diffusion value is affected by the drying temperature and the increase in temperature also increases the effective diffusion value. It has been determined that the effective diffusion value varies between 1.35×10-7-5.92×10-6 m2/sec. The activation energy value of dried rosehip samples was calculated as 69,41 kJ/mol. When the chemical analysis values were examined, when the SÇKM, total phenolic, total antioxidant substance and vitamin C values were evaluated together, it was found that the most appropriate drying temperature was 70°C statistically. Among all drying models, Midilli-Küçük and Yağcıoğlu models (R2: 0.9999) estimated the drying data best.

This study was conducted to evaluate essential oils from Croton macrostachyus Hochst. ex Delile, Eucalyptus globulus Labill., Allium sativum L., Cymbopogon citratus (DC.) Stapf, Cymbopogon martini (Roxb.) W.Watson, Rosmarinus officinalis L. and Thymus schimperi Ronniger using four concentrations (l mL, 2 mL, 3 mL, 4 mL) and three sprays against potato (Solanum tuberosum L.) late blight disease. Two improved potato varieties were planted using randomized complete block design with factorial combinations in three replications. Analysis of disease incidence means at 53 and 60 days after planting showed highly significant differences between varieties and among sources of essential oils. Furthermore, the combined effect of essential oils and potato varieties on disease severity showed significant differences. Disease severity was maintained from 25% to 48% (Jalene); 13% to 30% (Gudene) with essential oils while it was maintained between 92% and 95% (Jalene); 37% to 38% (Gudene) for control plants. The lowest disease percentage of disease severity was obtained on plants treated with A. sativum for Jalene variety while on plants sprayed with C. macrostachyus, E. globulus and T. schimperi for Gudene variety. The lowest disease progress rate 0.198/day and 0.162/day as well as values of area under disease progress curve 228% days and 93% days were obtained for varieties Jalene and Gudene, respectively. Maximum reduction in mean disease severity was exhibited by garlic for varieties Jalene (28.3%) and Gudene (16.3%), as compared to the control (93.3% for Jalene and 37.5% for Gudene). Therefore, results indicated the potentials of essential oils to minimize effects of potato late blight disease. Communities involved in potato production could use the current results as base line information to find alternative management options for late blight disease which has no effect on human health and environment. However, further investigation is required on essential oils affordability and availability to farmers across different locations.

Salinity, which is one of the abiotic stress factors, severely restricts plant production as a result of the negative effects of plants in different growth and development periods. Therefore, it is extremely important to determine the tolerance limits of plants to salinity in order to eliminate the limiting effect in terms of plant growth. Flax is an industrial plant that is used for multiple purposes and has commercial importance in the world. This research was carried out in controlled laboratory conditions in 2021 to determine the effects of salinity on the germination of flax seeds. In the study, germination rate, root length, root fresh weight, shoot length and shoot fresh weight were evaluated. The result showed that significant differences between different NaCl solutions for all evaluated characters. Although the highest value was obtained in the control group in Mures variety, the highest value was obtained in 25 nM NaCl concentration in all other characters except for the germination rate in Dakota variety. The highest germination rate of 93.3% was obtained from the control application (0 mM NaCl) in both varieties. On the other hand, there was no germination in both varieties in 200 mM application.

Broiler production supplements income of smallholder farm households. Profitability and productivity and analysis are important considerations in measuring efficiency or performance of a farm business; hence, improved output and income are not only a function of increase in the scale of production, but also how efficiently the resources are being utilized. This study therefore estimates the profitability and level of productivity among broiler farmers in Jos North, Plateau State, Nigeria. Multistage sampling technique was employed to select respondents for this study. Primary data collected were analysed using descriptive statistics, farm budgeting model and Total Factor Productivity (TFP) analysis. The study revealed that the net farm income of broiler production was ₦96,900/flock size; suggesting a relatively profitable venture with prospects for improved economic potentials. The estimated percentage profit margin was 45.6%; indicative of the percentage net margin accruable to the farmer from the estimated gross margin and benefit-cost ratio was 0.84. Furthermore, most (54.3%) of broiler farmers were sub-optimally productive as their TFP indices were below the optimal scale; attributable to sub-efficient input mix and cost of production inputs. In addition, constraints of broiler production in the study area included the following; high cost of feeds (92.9); high cost of chicks (85.7%); financial constraints (80%); high cost of poultry equipment (55.7%); high cost of medication (35.7); disease outbreak (28.6%) and inefficient market system (21.4%). Improving access to and subsidy of poultry feeds, chicks, production inputs and credit, extension, medical services and cooperative formation for market linkages are strongly recommended.

The rapid increase in the world population increases the need for plant and animal food. Agriculture and animal husbandry practices are becoming more common day by day to meet the need for food and to obtain more products. This situation increases the amount of waste per unit of animal products. Increased animal excrement is associated with greenhouse gas emissions, harms the environment and animal health. One of these greenhouse gases, methane, increases animal production and poses a significant threat to global warming. Feeding research, which optimizes rumens and animal productivity to reduce ruminant methane emissions, is one of the hottest topics today. The purpose of this study is to evaluate feed distribution in terms of chemical composition, methane production, net energy, and organic matter digestibility by collecting forage and concentrates from various ranches in Niğde. Therefore, to increase the productivity of livestock on small farms in Turkey, the ratio of feed ingredients was determined on a farm basis, and there were some comments on the lower and upper limits of the fattening rate. Gas and methane production of TMR samples was determined using in vitro gas production technology. Nutrient contents obtained from different livestock farms CP (9.58-14.72), CF (1.89- 2.30), CA (7.64-13.92), ADF (19.77-27.82) NDF (36.71-45.69) DM (90.48-91.79) content, methane (CH₄), OMS, NEL and ME values were also different (P
