Abdalla Mohamed Hussein | Mebrouk Benmoussa
The objective of this study is to investigate the planting density, nitrogen and potassium influencing on the pod characteristics of bean. The experiment is made in a Split Randomized Complete Block Design, replicated three times. Two plant densities and seven doses of nitrogen and potassium fertilizers were examined. The results reflected that density had no effect on pod attributes, except pod length in the second season, whereas significantly increased by the lower density. The plant received lower nitrogen lacking potassium increased length in the both seasons however, the higher individual potassium dose and control increased length in first and second seasons, respectively. The widest and narrowest pod diameters shown by the lower dose of nitrogen and higher dose of both fertilizers, subsequently. The separately maximum and minimum dose of potassium in the first and second season subsequently, in addition to the individual lower dose of nitrogen in the second season have a heaviest dry weight. The interaction significantly affected overall parameters, except pod diameter and dry matter in the first season. Pod dry matter is commonly constant, except with the higher density received the greatest dose of both fertilizers, whereas record significant decline. Pod length and diameter are good indicator of quality, it can be given by the lower density and lower dose of nitrogen without potassium. The combination between lower density with higher potassium dose or neutral dose of both fertilizers is a preferable for length while, the higher density with both doses of potassium or with lower nitrogen, is an appropriate for diameter. The best treatment for both, dry weight and dry matter are wobbly.

Hakkı Mümün Ay | Adnan Söylemez | Nihal Güneş Ay
In recent years, intensive legal regulations aimed at the production of urban areas in Türkiye, the phenomenon of migration, the spread of higher education, abnormal cost increases in agricultural activities have accelerated urbanization. Parallel to the increase in the urban population, the food supply remains insufficient. The inability to increase the production of food products brings with it problems such as malnutrition, inflation, foreign trade deficit, food security. The natural areas harbored by rural and urban areas are shrinking and being destroyed by the pressure of rapid urbanization. In addition to the abandonment of rural areas, the food crisis that has arisen as a result of the intervention of the urbanization process in agricultural areas has increased the responsibility of the central government and municipalities. In order to meet the food needs of the population and implement sustainable agricultural policies, municipalities are taking different and innovative approaches. Municipalities are making direct and indirect attempts to provide people with cheap and reliable food. In this study, the activities carried out by the municipalities in Türkiye to support sustainable agriculture and their economic and social effects were examined.

Sweet cherry, which affects consumers’ preferences with its aroma, taste and sensory properties, is a significant fruit species for human health with its bioactive compounds such as organic acids, vitamins and anthocyanins. However, its post-harvest shelf life is very short due to its sensitive fruit structure. Thus, the significant economic losses occur. In the study, effects of pre-harvest Aminoethoxyvinylglycine (AVG), Salicylic acid (SA) and plant growth promoting rhizobacteria (PGPR) applications on fruit quality characteristics and biochemical content in sweet cherry were determined. SA and PGPR treatments increased fruit size, but AVG decreased (If the fruit weight is 4.51 in the control application, 4.49 in the SA application and 4.10 in the PGPR, how can it be said that SA and PGPR increase the fruit weight). The fruits treated with SA, AVG and PGPR had higher fruit firmness values than the control’-fruits. Salisylic acid treatmens did not affect the rate of soluble solids content(SSC) in fruit, SSC rate was higher in PGPR treated-fruit, but AVG decreased the SSC. Titratable acidity (TA) was lower in PGPR treated-fruit, but was higher in the AVG and SA treated-fruit. Fruits treated with the SA and AVG had higher fruit color values than control fruits, while the lowest color values was obtained with PGPR treatment. In general; PGPR, SA and AVG were effective in the concentration of organic acids, but their effects varied depending on the organic acid compounds. As a result, AVG and SA delayed fruit ripening and fruit softening while PGPR, AVG and SA improved fruit quality (It is not clear how this idea was reached). These applications can be considered as a promising method for improving fruit quality at harvest and maintaining post-harvest fruit quality of sweet cherry.

The use of cassava for fuel ethanol production in Nigeria is supported by the Nigerian Biofuel Policy and Incentives (NBPI) of 2007. Because of its food, feed and industrial value, the need to replace cassava with crops/plants that are food and feeds neutral has motivated this research. Starch was extracted from forest anchomanes (FA) (Anchomanes difformis (Bl.) ENGL.) tubers and some of its physicochemical and elemental properties were determined. At present, the plant is uncultivated in Nigeria and other parts of Africa where it is found. Results showed that the starch content in FA tubers varied from 72.12 to 75.83%. Starch granules from all parts of the FA tubers had similar proximate, antinutrients and elemental properties and appeared usable for fuel ethanol production. However, to suggest its potential to sustainably replace cassava, further investigations are needed beyond these initial results.

Güneycan Akyol | Muzaffer Denli
The purpose of this study was to determine the dietary effects of fruit pulps (dried tomato, apple and grape) on the performance and egg quality characteristics of laying hens. In this trial, 196 Lohmann sandy layers 25 weeks of age were distributed into four groups with seven replicates for 9 weeks. Trial groups fed following diets, control group basal diet (no additive), 4 % dried tomato pulp, 4% apple pulp and 2.5% grape pulp. Feed conversion rate was not affected by any addition of fruit pulps throughout the trial. The dietary inclusion of dried tomato pulp increased feed consumption, egg weight and egg production and decreased egg yolk malondialdehyde (MDA) levels on day of 1 compared to the control. Egg yolk MDA level was decreased with the addition of 4% tomato and apple pulp to the diet, but increased with the addition of 2.5% grape pulp to the diet on the day of 28. Moreover, the addition of dried tomato pulp to the basal diet significantly increased egg weight and egg yolk yellow color (a). As a result, this study provides evidence that adding up to 4% tomato pulp to diets may be used without adverse effects on laying hens’ productivity and may improve egg quality characteristics by decreasing MDA levels in the yolk.

Drying is the simultaneous transfer of heat and mass, which is defined as the reduction of moisture in food. The aim of the study the drying performances of refractance window drying (95°C), fluidized bed drying (95°C, 2m3/m air velocity), and convective drying (95°C) were examined in the drying of Maraş green pepper (C.annuum). Drying performance was evaluated for effective diffusion coefficient (Deff), activation energy (Ea), Chroma (C) and total color change (ΔE). Drying curves were obtained by recording sample weights in 10-min periods. For the refractance window drying, fluidized bed drying and convective drying the time for the samples to reach 6-7% humidity level according to the wet base was found to be 70, 80 and 110min, and the effective diffusion coefficient was 6.49x10-10, 5.68x10-10 and 4.87x10-10 m2/s the activation energy was 53.54, 54.65 and 55.93kJ/mol, respectively. When the color properties are examined the Chroma value was determined as 18.23, 8.85 and 4.80 and the total color as 15.42, 26.29 and 30.33, respectively. It was seen that the closest value to the fresh product was in the samples dried with a refractance window drying. In the study, it was concluded that the use of a refractance window drying shortened the drying time by 14-36%, increased the effective diffusion coefficient, provided drying with lower activation energy, and better preserved the color quality in the production of dried Maraş green pepper.

Safe meat production is an important aspect to avoid human health hazards. The use of probiotics in poultry is an important tool to produce safe meat among several established biotechnological approaches. In this experiment, we studied the effects of probiotics for producing safe Japanese quail meat. 150 Japanese quail chicks were reared for a period of six weeks using various doses of probiotics (0, 0.5, 1, 1.5, and 2g per litre of water). The chicks were randomly distributed into five treatment groups with three replications each. The number of birds in each replication was 10. After rearing six weeks, significantly high body weight was found at probiotic concentrations of 1, 1.5, and 2g per litre of water. The feed intake in various treatments did not differ significantly, but comparatively better feed conversion ratios were observed at probiotic treatments. Water quality was not significantly differed as a result of addition of probiotics to the water. The reason for this better growth performance is probably due to the multiple benefits of probiotics in poultry. Probiotics could have maintained gut health with better nutrient utilization and availability that might have been led to higher body weight gain in the quail. In future experiments, challenging the birds with diseases or comparing probiotics with antibiotic growth promoters is required to ensure the efficiency of probiotics.

This study investigated the effects of various guar gum edible coating formulations, incorporating different proportions of waste leek powder and sunflower oil, on weight loss, color parameters (L*, a*, b* values, and ΔE), texture, and shrinkage of Agaricus bisporus mushrooms during a 7-day storage period. The goal was to assess the potential impact of these coatings on preserving the mushrooms’ quality over time. The results showed that the coatings had a significant effect on reducing weight loss compared to uncoated samples. The lowest weight loss was observed in the 0.5% leek powder and without sunflower oil, while the highest was in 2.5% leek powder and 0.1% sunflower oil. Shrinkage was also positively affected by the coatings, with 1.5% leek powder and without sunflower oil showing the most promising results. The L* values of the coated samples declined slightly, indicating better color preservation, while the a* values exhibited stable redness/greenness. On the other hand, b* values increased, indicating an increase in yellowness during storage. The ΔE values were lower for the coated samples, suggesting less color deviation compared to uncoated ones. Overall, the study indicates that these edible coatings have the potential to maintain the quality of mushrooms during storage, leading to better preservation and extended shelf life.

Erzincan Tulum Cheese (ETC) holds a significant place among the most popular cheeses in Türkiye. It has been awarded Protected Geographical Indication status, which restricts the allowable milk species, its production area, and specific sheep breed used in its production. Mineral content and antioxidant activity of ETC were aimed to be predicted using conventional FT-NIR and a portable FT-MIR spectrometer combined with partial least square regression (PLSR) and machine learning algorithms based on conditional entropy. Seventy ETC samples were analyzed for their mineral (Al, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, and P) content using ICP-MS. The samples' antioxidant activity was measured using the DPPH•+ scavenging activity method. PLSR combined with FT-NIR spectral data correlated with antioxidant activity (r=0.89) and minerals (as low as r=0.83) except for Cr and Fe. FT-MIR data provided a good correlation for minerals (as low as r=0.82) except for Cr and Mn and a moderate correlation with antioxidant activity (r=0.64). Information theory was applied to select wavenumbers used in machine learning algorithms, and better results were obtained compared to PLSR. Overall, FT-NIR and FT-MIR spectroscopy provided rapid (~ 1 min), non-destructive, sensitive, and reliable output for mineral and antioxidant activity predictions in commercial cheese samples.
