The depletion of minerals in agricultural soils through subsistence farming has been a major food security challenge in many parts of the world. To curtail this problem, farmers use inorganic fertilizer to boost soil fertility even though it poses a lot of environmental challenges. In this research, an alternative route to soil nutrient amendment was explored via the use of compost and nano-gel water accumulator for blending different soil samples derived from rock side soil and spent farm soils blended in different ratios of 1:0, 1:1, 1:2, and 2:1using a suitable potting media for the greenhouse production of A. spinosus L. Physicochemical values, mineral, and heavy metals concentration were evaluated on the soil and compost samples while mineral, proximate, anti-nutrients and vitamins compositions were analyzed on A. spinosus L. grown on the soils. Data obtained were analyzed using analysis of variance (ANOVA) at a 95% confidence limit using SPSS 20.0 software. The properties of the prepared compost (PC) and commercial compost (CC) varied significantly (P

Studies on the maturation of mangoes in growing regions may help determine the optimal harvest strategies to support proper post-harvest handling and improve the fruit shelf life. The aim of the present study is to evaluate changes and establish correlations of physical and mechanical parameters during the ripening of mangoes cv. 'Tommy Atkins' collected from fifty plant rows in a commercial orchard. The fruits were picked at 35, 50, 65, 80, 95, 110, 125 and 135 days after flowering (DAF). Fruit mass, longitudinal diameter (LD), transverse diameter (TD), fruit firmness, force and maximum deformation compression, tension and Hencky’s strain were evaluated. The statistical design was totally randomized with four replications with ten fruits each. The results were submitted to longitudinal data analysis due to the quantitative nature imposed by the harvest time factor. Hencky’s strain curves and deformity underwent an analysis of the standard error of the mean. From the beginning of the harvest up to 125 DAF, the fruit went through an increase in its mass, in its longitudinal and transverse diameters and in its compressive strength. Both physical and mechanical parameters exhibited high correlation, up 0.93, as regards the fruit maturation stages. This demonstrates that the mangoes cv. 'Tommy Atkins’ hold excellent prospects of development.

Bu çalışmada besinsel lif ve β-glukan yönünden zengin fonksiyonel bir gıda olan yulaf ezmesi ile fenolik maddelerce zengin, yüksek antioksidan içeren yaban mersini kurusu çikolatada katkı olarak kullanılmıştır. Yaban mersini kurusu ve yulaf ezmesi 1:1 oranında karıştırılarak elde edilen karışım sütlü kuvertür çikolataya %10, 20, 30, 40, 50 oranlarında ilave edilmiş ve kalorisi düşük ve sağlıklı bir ürün elde edilmesi amaçlanmıştır. Hazırlanan katkılı çikolata örneklerinin nem, kül, karbonhidrat, yağ, protein, selüloz, şeker ve enerji değerleri saptanmış ve örneklerin genel görünüş ve genel kabul edilebilirlik özellikleri duyusal olarak incelenmiştir. Çalışma sonucunda kuvertür çikolataya eklenen yulaf ezmesi ve yaban mersini kurusu karışımı örneklerinin nem değeri (%0,35-4,90), kül içeriği (%2,24-1,43), karbonhidrat değeri (%55,82-66,57), yağ miktarı (%33,20-20,05), protein miktarı (%8,49-7,09), selüloz miktarı (1,03-1,90), şeker miktarı (%39,30-46,87) ve enerji değerleri (%467,57-550,86) olarak belirlenmiştir. Duyusal analiz sonuçlarına göre ise yulaf ezmesi ve yaban mersini kurusu karışımının çikolatadaki miktarı arttıkça tercih edilme oranının azaldığı görülmüştür.

The effect of the two tractor wheel arrangements-double field wheel/single furrow wheel (double Re/single RS) and single field wheel/single furrow wheel (single RC/single RS,) on the effective field capacity in ploughing, was studied in order to prove that the arrangement double RC/single RS provides less costs per hectarea and greater effective field capacity. The field trials were carried out in eigth plots of 3750 m2 each one, employing two treatments (tractor wheel arrangements) and four replications. The tractor wheel arrangement double RC/single RS showed the greatest effective field capacity and the lowest costs per hectarea in comparison with the arrangement single RC/single RS. | Se estudió el efecto de los arreglos rueda de campo doble/rueda de surco sencilla (RC doble/ RS sencilla) y rueda de campo sencilla/rueda de surco sencilla (RC sencilla/RS sencilla) sobre la capacidad de campo efectiva (CCE) en labor de arada, bajo la hipótesis general de que  con doble rueda motriz de campo es de esperar una mayor capacidad de campo efectiva, debido a la reducción en el patinaje del conjunto tractor-arado. Se empleó un arado de tiro de discos con un ancho de corte de 90 cm, arando a una profundidad promedia de 26 cm. El arado se operó con un tractor de 45 k W. El ensayo se realizó en un lote de 5 ha de 200x250 m, el cual se aró por el sistema de melgas en el sentido más corto, para poder trazar ocho melgas de 25 m de ancho cada una. Las melgas hicieron las veces de parcelas experimentales, cada una con un área de 3750 m2; el ensayo se planeó con dos tratamientos (arreglos de ruedas) y cuatro replicaciones (melgas). En cada melga se midió el tiempo de campo, descontando aquellas pérdidas que no se debieron a los tratamientos aplicados (pérdidas debidas a fallas en el equipo que normalmente se presentan en este tipo de labores), con el fin de conservar la igualdad de condiciones en todas las parcelas. Con el arreglo RC doble/RS sencilla se obtuvo mayor capacidad de campo efectiva en comparación con el arreglo RC sencilla/RS sencilla; al hacer análisis de varianza la diferencia fue significativa (P≤ 0.05). También se registró una diferencia en costos de $1.266/ha menos a favor del arreglo RC doble/RS sencilla.

Bovine leukemia virus (BLV) is known as the causative agent of enzootic bovine leukosis (EBL), which is a worldwide distributed disease and has also been detected in marketed beef and dairy products. BLV causes significant economic losses due to the loss of milk and yield or the slaughter of animals without adequate development. It has been reported in epidemiological studies that this infection is common in Türkiye, especially in the western provinces. There is no data on the possible presence or prevalence of BLV infection and its seroepidemiology in Muş province. The aim of this study is to determine the possible presence and prevalence of the infection, its role in yield losses, and to obtain epidemiological data on cattle farming in the Muş district. For this purpose, 300 blood serum samples were collected from cattle aged six months and older in the province of Muş and its different districts. The blood serum samples taken were tested for the presence of BLV-specific antibodies by agar gel immunodiffusion (AGID) and competitive enzyme-linked immunosorbent assay (C-ELISA) methods. As a result of the study, all of the controlled districts were evaluated as negative in the AGID and C-ELISA tests for the presence of BLV-specific antibodies. In conclusion, for the first time, it was demonstrated that cattle farming in the Muş province were BLV-free during the sampling period. Although BLV seropositivity was not detected in the tested animals, it is emphasized that the control of infection and eradication program should not be ignored.

The objective of this study is to diagnose the potato sector in the El Oued region by highlighting the technical and environmental situation of this sector. For this purpose, a field survey was carried out at the level of 75 farms in the El Oued region. The Oued Souf region’s Farm Sustainability Indicator (IDEA) is important. The assessment of agro-ecological, socio-territorial and economic indicators indicates that the agro-ecological indicator is the most represented by (the indicator of fertilizer and agricultural practices) by 98 out of 100. The results of this study show that this crop presents a good adaptation to the conditions of the region. This sector is undergoing significant development and is of great importance because this agricultural activity represents an economic potential at the local, regional and national levels. However, this sector remains fragile in relation to various constraints of a technical nature (unreasonable irrigation and fertilization and high seed prices), economic (price fluctuations and disorganized markets) and environmental (diseases, weeds) which directly influence the functioning of farms and therefore their profitability. This is why it is necessary to face the problems encountered and fight against the factors that can hinder the sustainability of this sector and give a competitive value.

The prices of raw materials necessary for production play an important role in the production decisions of farmers, and thus in shaping the level of supply of agricultural raw materials. The constant increase in the prices of raw materials for production increases its costs. Therefore, it should be noted that the rising prices of fuel and fertilizers affect the decisions and profitability of plant production. In connection with the above, this study attempts to indicate the impact of changes in fertilizer and fuel prices on the profitability of production of selected agricultural crops in Poland. The paper uses secondary data on the price level of fertilizers, fuels and selected agricultural products, as well as the structure of their production costs. Based on the sensitivity analysis, the potential impact of the increase in fuel and fertilizer prices on the profitability of the production of selected species was indicated. The results showed that the increase in the prices of the above-mentioned raw materials can significantly affect the economic efficiency of the production activity.

In this study, the reproductive and growth performance of Akkaraman sheep between 2017-2021 were evaluated within the scope of the National Sheep and Goat Breeding Project in the Hand of the Public, which is being carried out in the province of Nigde. In the research, data obtained from 30923 animals in 22 farms in 7 villages in the central district of Nigde province were used. In the study, the effect of year, dam’s age, gender and birth type on birth weight (BW), live weight on day 60 (LW1), live weight on day 120 (LW2), daily live weight gain (DLWG) on day 120 were investigated. The effects of year, dam’s age, gender and birth type on BW, LW1, LW2, DLWG were found to be statistically significant. While the effects of year, dam’s age and gender were found to be statistically effective on SR, the effect of birth type was found to be insignificant. In the study, fertility, fecundity and litter size in Akkaraman lambs were determined as 0.92, 1.03 and 1.13, respectively. As a result, remarkable progress has been achieved in Akkaraman lambs in terms of performance characteristics (LW1, LW2 and DLWG) between 2017 and 2021.

This experiment investigates the effect of flaxseed meal, rapeseed meal and vitamin E supplementation, when used together, on the production parameters of fatty acid composition and eggs quality characteristics in Tetra SL laying hens (38 to 46 weeks of age). For this, 120 hens were allocated one of three treatments, with 40 hens in each group. The hens were fed either a control diet (C), a control diet including 2.5 % flaxseed meal and 2.5% rapeseed meal (E1) or 2.5% flaxseed meal and 2.5% rapeseed meal with 73 mg/ kg feed of vitamin E as an antioxidant supplement (E2) for 8 weeks. Hens consuming the E1 diet had greater egg production and egg mass than those from group C. The feed conversion ratio in both the E1 and E2 groups was lower (P < 0.05) than in the C diet group. E2 had considerably higher egg weight, albumen pH, yolk pH and Haugh unit than E1 and C (P0.05), as a response to the vitamin E antioxidant effect. The most α-linolenic fatty acid content (1.07 g FAME) was found in eggs produced by chickens fed the E2 diet, (1.07 g FAME), followed by E1 (0.91 g FAME), with both being significantly higher than C eggs (0.23g FAME). Furthermore, all n-6 studied fatty acids concentrations were significantly lower (P < 0.05) in E1 and E2, while all n-3 fatty acids concentrations were significantly greater (P > 0.05) in E1 and E2. When comparing the n-6/n-3 ratio of fatty acids from experimental treatments (6.44 and 6.74) with C treatment (18.19), a significant difference was observed (almost 65% lower).

The aim of this study is to determine the effects of adding different levels of red pepper oil to quail diets on performance, slaughtering characteristics, and some serum parameters. For this purpose, a total of 300-day-old and mixed-sex quail chicks were randomly assigned to 5 treatment groups with 6 replications of 12 chicks each. Experimental animals were fed for 35 days with 5 different diets prepared by adding 0, 300, 600, 900 or 1200 mg/kg red pepper oil. During the experiment, quails were given ad-libitum feed and water. According to the results of the experiment, the effect of adding red pepper oil to the diet on the performance, carcass traits and visceral weights of the quails was statistically insignificant. Triglyceride and TAS concentrations of serum were significantly affected by the addition of red pepper oil to the diet. The highest triglyceride and TAS levels in the group with 300 mg/kg red pepper oil added; however, the lowest triglyceride and TAS levels were obtained in the groups supplemented with 600 mg/kg and 1200 mg/kg red pepper oil, respectively. According to this study findings, it can be said that the addition of red pepper oil to the diet in growing quails has a positive effect on serum triglyceride and TAS values when used between 300 mg/kg and 600 mg/kg in the diet, without adverse effects on performance and carcass characteristics.

Se compara el crecimiento de plántulas de la orquídeas epifita Tolumnia variegata en medios de agar con y sin hongos micorrízicos. Los métodos de germinación simbiótica produjeron embriones de T. variegata más desarrollados que los métodos de germinación asimbiótica y las diferencias fueron estadísticamente significativas. Las semillas en los controles en medio de celulosa sin hongos micorrízicos no germinaron. Las semillas de Epidendrum ramosum, Lepanthes rupestris y Psychilis monensis no mostraron diferencias significativas en germinación entre métodos simbiótica y asimbiótica utilizando hongos aislados de raíces de T. variegata, incluso algunos aislados del grupo Rhizoctonia parasitaron las semillas. Los resultados sugieren que las semillas de orquídeas epifitas y sus hongos micorrízicos son más específicos de lo que anteriormente se había creído y por tanto es necesario utilizar los hongos específicos para cada especie de orquídea. Además, se sugiere que los cultivadores de orquídeas podrían obtener mejores resultados en la propagación de orquídeas epifitas si utilizan metodologías de germinación simbiótica apropiados.

Symbiotic germination produced more-developed embryos than asymbiotic germination. Differences were highly significant, although some isolates of Rhizoctonia-like fungi were parasitic on seeds. Control seeds in a cellulose medium without Rhizoctonia-like fungi did not germinate. Seeds of Epidendrum ramosum, Lepanthes rupestris and Psychilis monensis showed no significant differences between asymbiotic and symbiotic germination using mycorrhizal fungi isolated from T. variegata roots, suggesting high mycorrhizal specificity. Our data suggest that the relationship between epiphytic orchids and the mycorrhizal fungi is more specific than previously thought. The use of the right fungal strain may enhance germination performance. Orchid growers may achieve better results in the propagation of some epiphytic orchids using symbiotic germination.

The paper presents tests connected to the torrefaction of agro-biomass residues as a case of biomass valorisation. The aim of the work is to compare the changes in energy and chemical properties of millet stalk (Panicum miliaceum L.) before and after the torrefaction process. The torrefaction of the millet stalk was done by using a scale reactor in two temperatures, 275oC and 300oC, in an N2 atmosphere. The millet stalk torrefied at 300oC has more promising parameters, i.e., higher heating value HHV 24,57 MJ/kg, the content of carbon 64,90% and energy density 1,42 compering to biochar produced at 275oC - 22,57 MJ/kg, 60,90% and 1,31 respectively. The results showed that torrefaction improves the parameters of the millet stalk for higher-quality biofuel, which can be used for heat generation.

Hungary and Turkey have a considerable share in world wheat markets. In 2018, Hungary’s export value of wheat and wheat flour reached to 411 million euros and it formed 32 per cent of overall cereal & milling industry export value of the country. Export value of Turkey for the same commodities was 875 million euros in the same period and it formed 77 per cent of total cereal & milling industry export value (International Trade Centre, 2019). Considering their potential and recent upward trends in trade, this study aims to determine the competitiveness of the wheat sectors in Hungary and Turkey. The study examines the competitiveness level of both countries by using Balassa’s Revealed Comparative Advantage index and Michaely index. The examination range covers the 10-year period between 2009 and 2018. Majority of data in this work was obtained and derived from International Trade Centre database. According to analysis results, Hungary has a higher degree of specialization vis-a-vis Turkey.
