The study evaluated the production of pods and green grains in garden peas in relation to some biostimulating substances. The experiment was organized in the area of Aldesti locality, Arad County, Romania. Four pea varieties were cultivated: Vidra 187 (a1), Udina (a2), Ișalnița (a3), and Marifon (a4). Three biostimulators were used: Fabo (b2), Bionat (b3), Lithovit (b4), tested together with a control variant (b1). From the combination of the two factors, 16 experimental variants resulted. A logical scheme was designed for the experimental flow. According to PCA, correlation, in relation to Pgp (peas green pods), Pgp Q1 (peas green pods quality I) and Gp (green peas grains), as biplot, PC1 explained 86.788% of variance, and PC2 explained 13.079% of variance. The cluster analysis led to the dendrogram of grouping the variants based on similarity in relation to the considered parameters. The regression analysis led to models of equations and graphs (3D, isoquants) regarding the variation of Gp in relation to Pgp and Pgp Q1. The a2b4 variant facilitated the best values for the analyzed parameters (Pgs, Pgs Q1, Gp).

Numerous sports disciplines employ Arabian horses. The use of Arabian horses bred in Turkey for flat racing and javelin (jereed) sport was examined in this study, as well as the effects of aging. 13 different physical sections of Arabian male horses were measured, 43 of which competed in races at the racetracks in Ankara, Adana, Bursa, and Şanlıurfa, and 58 of which took part in javelin competitions in the heart of Erzurum. When the body measurements of male Arabian horses used for javelin and racing were compared, it was found that there were differences in the croup length (p < 0.01), back length (p < 0.001), chest depth (p < 0.05), chest circumference (p < 0.001), pectoral chest width (p < 0.01), neck circumference (p < 0.001), and hock circumference (p < 0.001). The changes in the withers height, croup length, and chest circumference of male Arabian horses at different ages were found to be significant (p < 0.05), but not in the other body measurements (p > 0.05). The pectoral chest breadth and hock circumference were shown to be significant in the usage area of horses (JAVELIN-RACING) x age interaction (p < 0.05). The choice of Arabian racing horses for the javelin or training purposes was thought to have altered the anatomical structure, which could account for the differences in various body measurements between racing and javelin horses.

Aphids are important pests in fields and orchards. The use of chemical insecticides as the main control method resulted in many ecological and health problems. Thus, the development of alternative methods, such as botanical bio-pesticides becomes indispensable in recent years. In this context, we studied the insecticidal and repellent effects of different concentrations of essential oils (EOs) and aqueous extracts from Salvia microphylla (Lamiaceae) against Aphis craccivora aphids, under laboratory conditions. The results showed that higher concentrations of extracts (10000 ppm for EOs and 10% for aqueous solutions) proved significant aphicidal activity, where mortality rates of 100% and 74% were noticed, respectively. Furthermore, aqueous extract at 10% concentration recorded the highest repellent effect (repellency rate = 71.8%). Therefore, the use of extracts from S. microphylla may constitute an important tool in integrated pest management.

The paper aims to present the situation of agricultural lands and the effects of their management on the sustainable development of agriculture in the North-West Development Region of Romania, at the level of 2023. The study is based on data taken through the sociological survey method based on a questionnaire, of a number of 276 respondents. The collected data were interpreted for the following indicators: the type of agriculture practiced, agricultural techniques applied, the involvement of agricultural farms in associative forms, the surface of agricultural land, irrigation of agricultural land, fragmentation of agricultural land, types of crops and the use of modern technologies for a digital agriculture. After analysing the data, it is observed that a predominantly conventional and mixed agriculture is practiced, using an average of 150 hectares per farm. Due to the large presence of arable land, the main crops are field crops, represented by cereals and fodder plants. Permanent crops represented in particular by permanent meadows are owned by the majority of farmers (87.3%), and horticultural crops are present in only 27.17% of farms. Modern technologies have a high potential in the development of the region and must be exploited more in the future.

The research addresses an original and complex topic concerning the evolution of the main chemical properties of the chromic luvisols in the southwestern part of Romania, in Dolj County, exploited under the specific cultivation conditions of agritourist farms. The novelty of this research consists in the multidisciplinary interpretation of the analyses on chemical properties and their influence on the quality and quantity of agricultural productions. In the second part, the main chemical properties of the chromic luvisols were analysed, both for the soil developed under woody vegetation, and both for the cultivated soils. Comparing the results of the analyses, we found that the natural fertility of the cultivated soil decreased considerably, which led to a significant deterioration of the main chemical properties, precisely due to cultivation. In the third part, a study was carried out on the presence and concentration of heavy metals in this type of soil, finding from the interpretation of the analyses that the values of all the studied elements fall below the alert threshold. he recommendation on the researched aspects is that in order to limit the degradation and even improve the main chemical properties of chromic luvisols, in the agritourism farms, an ecological agriculture must be practiced.

The Romanian Senate has adopted in May 2023 a legislative proposal that obliges landowners to remove Ambrosia artemisiifolia L. (also known as the common ragweed) throughout the year, forcing local authorities to penalize those who do not eliminate this plant species. In this context, the present study aims to highlight the Romanian people’s perceptions and attitudes on “ambrozia”, given the fact that this invasive plant represents nowadays a real threat to environment and also to public health, its pollen causing allergic rhinitis. In order to analyze the citizen’s knowledge about the common ragweed, between February and June 2023, an online survey was launched. The anonymous questionnaire was filled out by 585 voluntary participants recruited online from all over the country. The mixed views about the importance of A. artemisiifolia are discussed herein. In addition, the Toolkit “STOP AMBROZIA” was created in April 2023 by Let’s Do It Romania - the partner of Faculty of Agriculture within USAMV of Bucharest - and currently this useful resource can be consulted and free downloaded accessing the Association’s website.

Soil quality degradation can be attributed to both individual and industrial human activities, directly or indirectly. The depletion of soil nutrients, specifically nitrogen (N), phosphorus (P), and potassium (K), contributes to a decline in soil fertility. Sodium alginate, when employed as a planting medium, exhibits notable efficacy in the absorption and subsequent release of nutrients and water due to its inherent stability. The robust capacity for absorption and resilience to SA is attributed to covalent crosslinking with elemental hydrogen or essential plant nutrients. The ionotropic gelation process was used to make alginate hydrogel, and a solution of CaCl2 was used as the crosslinking agent. The results of this study suggest that augmenting the potassium concentration can enhance plant growth rate, hence aiding the attainment of optimal plant height. Sodium alginate-based hydrogels exhibit potential as a feasible alternative for utilization as planting substrates
土壤质量退化可直接或间接地归因于个人和工业人类活动。土壤养分，特别是氮（N）、磷（P）和钾（K）的消耗导致土壤肥力下降。海藻酸钠在用作种植介质时，由于其固有的稳定性，在吸收和随后释放养分和水分方面表现出显著的功效。海藻酸钠强大的吸收能力和对 SA 的适应能力归功于与氢元素或植物必需营养素的共价交联。藻酸盐水凝胶的制作采用了离子凝胶化工艺，并使用 CaCl2 溶液作为交联剂。研究结果表明，增加钾的浓度可以提高植物的生长速度，从而有助于达到最佳株高。海藻酸钠水凝胶显示出作为种植基质的可行替代品的潜力

The paper presents the results of application of the method of automatic generation of representative and unbiased set for in-season cotton crop mapping, based on crop simulation model, previously parameterized using ground truth and satellite data. The method provided confident mapping of cotton fields without using actual ground-truth information or a-priori information about their in-season phenology. Overall mapping accuracy calculated using relevant ground truth data for cotton fields has reached 95.6 %. Consideration of time series of NDVI values as a model of phase characteristics allowed using relatively simple criteria to identify typical representatives of the selected crop on the basis of analysis of their seasonal phenology and made it possible to build a reference sample for modeling and further classification.

Consumers are increasingly demanding traditional beverages such as wines that are obtained through innovative technologies and that use indigenous yeasts to preserve the concept of `terroir`. The paper presents the study performed for the exploitation the microbial diversity in the Pietroasa wine region in Romania and to obtain autochthones yeasts biomass. Yeasts were isolated from grapes and must from Feteasca regala FR) and Cabernet Sauvignon (CS) varieties cultivated at the Pietroasa Viticulture and Vinification Research and Development Station. Five yeast isolates were selected and identified by the MALDI-TOF, these belonging to the S. cerevisiae and non-Saccharomyces genera. By using these yeast isolates, active dry biomass was obtained through fermentation on a substrate based on sterilised diluted must (from the Feteasca regala and Cabernet Sauvignon varieties), synthetic sterilised media, followed by freeze-drying. Subsequently, the active dry biomass was used to obtain wines, using two types of nutrients: ET (Energyvin Thiols) and NO (Nutristart® ORG). All studied yeast isolates showed a promising potential for obtaining white wine from Feteasca regala grapes and rosé wine from the Cabernet Sauvignon grapes variety.
