Consequently, Gliricidia sepium, a nitrogen-fixing tree, has emerged as a viable option serving as green manure and soil amendment in coconut plantations. However, determining the most appropriate stage for lopping Gliricidia to obtain its optimal nutrient compositions remains uncertain. Therefore, the primary objective of this study is to identify the optimal lopping stage of G. sepium as soil amendment in coconut plantations. The experiment was conducted over three months in an established Gliricidia field, following a Randomized Complete Block Design with three replicates. Plant samples were collected at 4, 6, 8, 10, and 12 weeks after initial cutting, corresponding to different growth stages. The samples were further analyzed to measure various growth parameters and nutrient contents across the lopping stages. The collected data were statistically analyzed using one-way ANOVA at a 5% significance level on Minitab 17 software. The results revealed significant differences (P<0.05) in the mean values of growth metrics and nutrient contents across the lopping stages. As the plant matured, the leaf biomass percentage showed a descending trend while the stem biomass percentage had an ascending pattern. At 10 weeks, leaves displayed the highest nitrogen content (3.43%), thus representing the optimal stage for fulfilling the nitrogen requirements of adult coconut palms, with minimal leaf biomass. These findings have identified the optimal lopping stage of G. sepium to maximize its efficacy as green manure for coconut cultivation. It is recommended that future studies further explore potential positive impacts of utilizing G. sepium as an intercropped green manure, thereby promoting sustainable agricultural practices within the coconut sector.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":"93 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141116486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Earnings management activities are identified using discretionary accruals computed with modified Jones model. Panel data analysis reveals that profitability and company size exert a positive and statistically significant influence on earnings management practices. Conversely, sales growth demonstrates a negative and statistically significant impact on earnings management. Furthermore, the analysis across the studied years indicates statistically significant differences in the prevalence of earnings management practices. However, the study found no significant differences in earnings management practices between the agriculture and manufacturing sectors. The significance of this study lies in its potential to provide valuable insights for investors, regulators, and financial analysts, helping them in making informed decisions. Moreover, it contributes to refinement of financial reporting standards and enforcement mechanisms, and enables a more accurate assessment of the financial health and performance of companies in both industries. The research also endeavors to identify sector-specific factors influencing earnings management dynamics, with the aim of enhancing transparency and optimizing decision-making processes in the financial environment.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":"33 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141117100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concerns for health, environmental protection, animal welfare, and support for the local economy contribute to greater purchases of organic foods, whereas high prices, lack of trust in certification, scarce supply, and unavailability of organic products represent obstacles to their purchase. This paper examined the prevalence of certain types of organic food in purchasing, as well as its relationship with the level of physical activity, gender, education, and age of the consumer. The sample consists of 600 respondents with different socio-demographic characteristics. The SPSS program was used for data processing. In addition to descriptive statistics, non-parametric techniques were also used due to the distribution of scores on the tested variables, which significantly deviates from the normal. The results obtained indicate that among the organic foods in the Republic of Serbia, fruits and vegetables are the most purchased, and that females, persons with higher education, and older people are the most typical buyers.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":"10 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141117571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being omnivorous and due to their relatively long lifespan, wide distribution and a relatively high number of shot animals per annual legal hunting season, they are suitable to be biological indicators of occurrence of heavy metals. Concentrations of cadmium, lead, arsenic and mercury were analyzed by atomic absorption spectrometry and cold vapor atomic absorption spectrometry in the livers of free-living wild boars (n = 58) from two locations in the Republic of North Macedonia. In all four examined heavy metals, no statistically significant difference between the locations was found (p > 0.05). The mean levels of heavy metals were Cd 0.391 mg/kg and 0.339 mg/kg; Pb 0.213 mg/kg and 0.204 mg/kg; Hg 0.034 mg/kg and 0.037 mg/kg; As 0.035 mg/kg and 0.029 mg/kg in the livers of boars from Bitola and Gevgelija hunting sites, respectively. Although some samples (two samples of Hg, ten samples of Cd and two samples of Pb) exceeded the legal limits, the average values for all heavy metals were far below the maximum permitted values. These findings are promising since they suggest that the ecosystem in the Republic of North Macedonia is stable concerning heavy metal pollution.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":"47 27","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141113239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Irrigated perimeters in these regions are subject to secondary salinization that negatively impacts soil quality and agricultural productivity. Monitoring and diagnosing the extent of soil contamination requires a more innovative approach to optimize rehabilitation of affected areas. In the present study, diagnosing of saline soil degradation is conducted by using two key indicators: electrical conductivity of saturated paste extract (ECe) and saturated hydraulic conductivity (HCs). The results of the study reveal that the value of ECe in 85% of the Lower Chellif Plain area (north-west Algeria) is ECe < 2 dS m−1, while 78% of the area is moderately permeable. These findings underscore high spatial variability in salinity distribution, indicating that the process of salinization has not yet reached a critical stage. Furthermore, it is concluded that ECe and HCs are appropriate indicators for diagnosing salinity of soil in relation to its structural and permeability characteristics.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":"30 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141113740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Farm economic viability was assessed using the opportunity costs of the main factors of production in agriculture (namely labour, land, and capital). The share of unpaid labour was found highest in the livestock farms specialising in milk production and grazing livestock. The farms specialising in permanent crops and horticulture had the largest share of their own utilized agricultural land, representing a very intensive type of farming usually organized on small acreages. The highest share of economically viable farms was recorded in the field crop farming system, followed by horticulture and permanent crops. In the viable group, the field crop farms were dominant with the largest coefficients of short- and long-term viability, which increased with the economic size of the farm. In general, the farms engaged in plant production exhibited much higher economic viability levels than the livestock farms (excluding the granivore farms). The most endangered were the farms specialising in grazing livestock, with the largest proportion of non-viable farms and the lowest coefficients of economic viability. A notable number of these farms lack economic justification for agriculture. However, ceasing agricultural production may not be the best solution for them, particularly as farms in remote rural areas are managed by elderly and low-skilled farmers.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":"139 41","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141114395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
