This paper is a short review of the Carum carvi L as a species of food interest, with many nutritional and functional benefits but also as a plant rich in bioactive compounds with antibacterial and antifungal action. For screening the cumin nutritional value and antimicrobial activity, we used different Databases and research papers.The nutritional richness in organic compounds (especially carbohydrates), vitamins (dominated by vitamin C, folates, niacin, vitamin E) and minerals (especially calcium, phosphorus) are the basis for the use of this plant as a spice in the food industry and in various culinary preparations. Carum carvi L seeds have a high oil content and over 30 chemicals. The most important components are considered carvone and limonene. Caraway oil is a promising antimicrobial agent against pathogenic, phytopathogene and fungal bacterial species, including species which produce mycotoxins and aflatoxins. Cumin is of interest in traditional medicine andalso for food preservatin.

Colonization of skin lesions with various infectious agents is still a major health threat. The misuse and abuse of antibiotics and synthetic drugs has led to increased resistance of pathogens and therefore difficulties in treating these medical conditions, requiring the development of new materials with antimicrobial efficacy. Thus, the aim of the study was to determine the therapeutic potential of hydrogels based on plant extracts (Chelidonium majus L., Arnica montana L., Calendula officinalis L., Aristolochia clematitis L., Hippophae rhamnoides L.) and zinc oxide nanoparticles in skin lesions by assessing cytotoxicity and cell viability. The two types of zinc oxide nanoparticles were obtained at 100 atmospheres and oven dried as well as at 100 atmospheres and spray dried. The data from our study suggest that none of the hydrogels tested show a notable cytotoxic effect on fibroblast culture. Dilution of the stock product in all experimental samples resulted in a cell viability of over 80%, reflecting that these hydrogels may be a therapeutic alternative in the wound healing process.

As part of this research, we made a dendrometric and ecological characterization of the Atlas pistachio stands located in the Naâma region through a series of dendro-architectural measurements and observations and floristic surveys. These stands are characterized dendrometrically by the presence of a pure stand with a regular structure dominated by very big wood (VBW) with 51,20%. The healthy tree and resilient tree ARCHI type are the most dominant with 65,10% and 23,20% respectively. From an ecological point of view, the stands studied harbor a low floristic diversity, made up of 21 species belonging to 20 genera and 13 botanical families. This low richness which is characterized by the dominance of chamaephytes (47,62%) and therophytes (23,81%) is the result combined of anthropogenic pressure and climatic aridity.

This study was carried out in 42 orchards located in the lowland of Develi, where the apple cultivation is intense in Kayseri province. The analyses were made to determine pH, CaCO3, EC, organic matter, available phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) in soil samples and nitrogen (N), P, K, Ca, Mg, Fe, Zn, Mn, Cu, and boron (B) in leaf samples. In the study, the relationships between some physical and chemical properties of the soils and the plant nutrient content of the leaves were evaluated by correlation analysis. In the study, between some physical and chemical properties of soils and the nutritional elements of soils and leaves were found important statistical relations. These relationships were mostly between soil samples rather than leaves. On the other hand, the pH and EC values of the soils showed less significant relationships with the nutrient contents of the samples according to the organic matter and CaCO3 contents of soils. It was determined that the organic matter content of the soils had a positive relationship with all the investigated elements except phosphorus. It has been determined that the relationship between the CaCO3 content and nutritional elements in the soils is statistically significant, it has a positive correlation with potassium and calcium and a negative correlation with other investigated elements. No significant relationships were found between the nutrient contents of the soils and the macro element contents of the leaves. While some important statistical relationships were determined between nutrient contents of the soils and micro element contents of the leaves, the highest correlation was determined between copper and boron contents. It was determined that the copper content of the leaves was positively related to the phosphorus, potassium and magnesium content of the soils and negatively related to the manganese content of the soils.

The role of antioxidative enzymes in response to heat stress tolerance (HST) of three tomato cultivars was investigated in this research. The leaves were obtained from tomato plants at the first bloom and yield stages and then were subjected to controlled high temperature treatments in water bath. The temperature in the water bath was increased 5 °C systematically for every half an hour from 35 to 60°C to generate a heat-stressed condition. The plants in yield stage exhibited an increase in HST when compared with the plants in first bloom stage and heat stress increased hydrogen peroxide (H2O2) level in leaves. Among the performed enzyme analysis, only catalase (CAT) involved in HST of tomato cultivars, however it may not be correlated with the degree of HST. In addition, two acidic and one basic isoperoxidases appeared in relatively heat tolerant cultivars in the yield stage, therefore isoperoxidases may be associated to HST in tomato plant.

The world's resources dedicated to fisheries and aquaculture are predicted to remain stable at their maximum utilization rate. Many intensive fish farms with recirculation production systems are needed in order to achieve sustainable output. Combined or integrated production projects are needed for sustainable production and to meet the high demand for food supplies. However, due to a substantial migration problem from rural areas to metropolitan centers, labor may be a concern in the aquaculture business. Turkey is still improving technology in order to maximize resource utilization while minimizing disruption to aquatic systems. With the growth of aquaculture, some environmental issues have been identified. Based on the present study, it was predicted that Tukey will produce 700,000 tons of fish by 2050. The purpose of this paper is to provide an overview of the current situation, as well as studies on sustainability and future developments in the field.

The biological properties of the sweet cherry (Prunus avium L.), as well as the physico-chemical characteristics of the fruit were studied for 3 years within RSFG Iași (2018-2020). The investigations were carried out at the Sârca Research Base on six varieties of sweet cherries. These included following the phenological stages (flowering period and fruit ripening period), but also the particularities of the fruit in terms of physical characteristics and biochemical composition. The highest weight of the fruit was recorded in 2020 in the ‘Regina’ cultivar. ‘Regina’ is characterized by an average flowering period, lasting between April 11th and 28th. The earliest cultivar both in terms of flowering and fruit ripening is the ‘Golia’ cultivar. All other varieties have an average fruit ripening period (June 15th-30th). The soluble dry matter content was between 11.29 (‘Hudson’) and 18.61 (‘Maria’). The researches carried out and the results obtained show that the studied varieties presented good results of adaptability in the pedoclimatic conditions in the area of Romania.

This work is part of the diversification of renewable energy sources, such as biomass for example. This research focuses on the recovery of date seeds which cannot be consumed by humans and are considered as waste. For this, the physicochemical and biochemical properties of these seeds were studied and determined. The results obtained allowed us to conclude that this waste product can be valorized for the production of biodiesel. Besides, the techniques adopted to achieve the best results in terms of quality were investigated as well. In addition, the process of extracting oils from date seeds was determined using the Soxhlet extraction procedure with a volatile solvent. The results obtained showed that the oil content of date seeds was estimated at around 4% to 5%, with a very high acid number (8.9776). This was achieved by means of the esterification and transesterification reactions, which allowed producing biodiesel. This method makes it possible to produce up to 91% of biodiesel with characteristics close to those reported in previous studies and recognized by international standards.

The aim of the research was to determine the effect of phosphorus fertilization (0, 30, 45, 60, 75 and 90 kg ha-1) on silage yield and quality traits of Persian clover (Trifolium resupinatum L.). The experiment was conducted at Yoruk village of Malkara-Tekirdag with three replications in randomized block design in 2021. Silage yield (t ha-1), dry matter (%), crude protein (%), crude ash (%), acid detergent fiber (ADF, %), neutral detergent fiber (NDF, %), P (%), K (%), Ca (%), Mg (%), digestible dry matter (DDM, %), dry matter intake (DMI, %), relative feed value (RFV), total digestible nutrients (TDN), net energy-lactation (NEl), net energy-maintenance (NEm), net energy-gain (NEg) and flieg score were determined. Silage yield, dry matter, pH, crude protein, ADF, NDF, P, Mg, DDM, DMI, RFV, TDN, NEg and Flieg Score were determined statistically significant at P˂0.01. The highest silage yield (72.83 t ha-1) and ADF ratio (25.36 %) were obtained from 30 kg P ha-1. The highest dry matter (39.92 %), DDM (70.30 %), DMI (3.22 %) RFV (175.056) and TDN (68.90) were found at application of 90 kg P ha-1. The highest flieg score was determined at application of 60 kg P ha-1. The highest crude protein (15.50-15.51 %) was found at application of 45 and 60 kg P ha-1.
本试验旨在研究施磷量(0、30、45、60、75和90 kg hm -1)对波斯三叶草青贮产量和品质性状的影响。实验于2021年在Malkara-Tekirdag的Yoruk村进行，采用随机区组设计，重复3次。测定青贮产量(t ha-1)、干物质(%)、粗蛋白质(%)、粗灰分(%)、酸性洗涤纤维(ADF， %)、中性洗涤纤维(NDF， %)、P(%)、K(%)、Ca(%)、Mg(%)、可消化干物质(DDM， %)、干物质采食量(DMI， %)、相对饲料值(RFV)、总可消化营养物质(TDN)、净能泌乳(NEl)、净能维持(NEm)、净能增重(NEg)和飞鸡评分。青贮产量、干物质、pH、粗蛋白质、ADF、NDF、P、Mg、DDM、DMI、RFV、TDN、NEg和Flieg Score在P小于0.01时均具有统计学意义。以30 kg P hm -1青贮产量最高(72.83 t hm -1)， ADF比最高(25.36%)。在90 kg P hm -1处理下，干物质(39.92%)、DDM(70.30%)、DMI(3.22%)、RFV(175.056)和TDN(68.90)最高。在施用60 kg磷-1时，飞蝇评分最高。45和60 kg磷- hm -1处理的粗蛋白质含量最高，为15.50 ~ 15.51%。
