Gender Differences in Entrepreneurship Education of the Students of Management

Martin Pech, Petr Řehoř

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 455-465 | DOI: 10.11118/actaun.2021.040  

The development of entrepreneurship competencies is not the primary objective of the management education system. Given the lack of student competencies required to start a new enterprise, the importance of entrepreneurship and economic education is increasing. There are new intentions from the Czech Republic's state politics that early business can be positively influenced and supported. The paper discusses entrepreneurship and its educational role. The research relies on a 214 questionnaire survey administered in 2018-2019 on students of the University of South Bohemia in České Budějovice. The paper focuses on the assessment of gender differences...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 467-472 | DOI: 10.11118/actaun.2021.041  

Damage caused by free living herbivores to field crops has been a significant and long lasting, culminating problem which has not been solved yet. One of the reasons is missing methodologies and lack of precise data. The aim of our study was to estimate a total extent of damage caused by free living herbivores to field crops in the Czech Republic. We carried out a field research, determined the extent of the damage to main crops, and calculated the total extent of damage. Maize was the most damaged crop with a total of 8.8% of damaged area followed by oat with 6.4%. A significant gap occurred between awned and awnless wheat. While 6% of awnless wheat...

Oluwatoyin Adenike Fabiyi, Gabriel Ademola Olatunji

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 473-480 | DOI: 10.11118/actaun.2021.042  

Field studies were conducted on the application of Leucaena leucocephala leaf extracts as an alternative to carbofuran a synthetic nematicide, while possible residues of carbofuran in tomato fruits were also analysed. Acetone, methanol and petroleum ether fractions of the leaves of L. leucocephala were applied at 200 mg/mL in variants of 100 mL, 150 mL and 200 mL to a naturally nematode infested field. Comparison was made with carbofuran a synthetic insecticide and nematicide. Samples of tomato fruits from carbofuran treated and untreated beds were extracted with ethyl acetate for residual pesticide analysis to ascertain the exceedance of the maximum...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 481-490 | DOI: 10.11118/actaun.2021.043  

The advent of bioremediation technology has helped scientists to proffer sustainable solutions to problems associated with environmental pollution. This study was staged to assess the growth of Amaranthus cruentus L. on spent engine oil (SEO) contaminated soil that had been subjected to bioremediation. Two bacterial co-cultures; Pseudomonas aeruginosa+Alcaligenes faecalis and Streptococcus pyogenes + Enterococcus faecalis were bio-enhanced with organic amendments; powdered cow dung (PCD), powdered cocoa pod husk (PCPH) and compost made from cow dung (CD) and cocoa pod husk (CPH) with a view to reclaiming SEO soil at three levels of contamination. It...

Antifungal Activity of a Composition of Selenium and Iodine Nanoparticles

Anatolii Vasylchenko, Stanislav Derevianko

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 491-500 | DOI: 10.11118/actaun.2021.044  

The aim of this study was to investigate antifungal properties of the composition of Se and I nanoparticles (NPs) against strains of phytopathogenic fungi Acremonium cucurbitacearum 502, Acremonium strictum 048 and Fusarium sp. 072. It has been found that the composition of Se and I NPs has antifungal properties against these strains. The highest antifungal activity was against strain A. cucurbitacearum 502, manifesting as the decrease in the number of colonies (by 60.00- 86.67%) and the decrease of the diameter of colonies (by 78.95-94.22%). Antifungal activity against strain A. strictum 048 manifested as the decrease in the diameter of colonies by...

Soil Microbial and Physicochemical Changes After the Addition of Biochar, Bacterial Inoculums and Nitrogen Fertilizer

Irina Mikajlo, Bertrand Pourrut, Brice Louvel, Jaroslav Hynšt, Jaroslav Záhora

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 501-510 | DOI: 10.11118/actaun.2021.045  

Addition of biochar is often proposed as an improving agent of soil properties. The combination of biochar (BCH) with mineral or biological amendments in order to improve its influence on soil-plant properties compared to the unamended BCH was vastly studied. Bacterial inoculums as a promising additive to BCH amendment are highly dependent on BCH quantity, its feedstock and soil state. Luvisol from a protection zone of water sources was used in pot experiment set-up. The changes in physicochemical properties (pH, cation-exchange capacity - CEC) and biological soil activities (soil enzymes: urease, phosphatase and laccase activity and total bacteria...

Effect of Hydro-priming and Salinity Stress on Germination Indices of Niger (Guizotia abyssinica Cass.)

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 511-518 | DOI: 10.11118/actaun.2021.046  

In order to evaluate the effect of hydropriming and Salinity stress on germination indices of Niger, a factorial experiment was conducted in a randomized complete block design with four replications at seed research laboratory of Shahrekord University. Salinity treatments were applied at five levels (0, 25, 50, 100 and 150 mM NaCl). Hydropriming treatments were applied at two levels (control and 6-hour hydropriming with distilled water). Results showed that the effects of hydropriming with distilled water and salinity stress on all the studied traits were significant at P ≤ 0.01. However, the interaction effects of hydropriming and salinity stress...

Formulation for Development of Low- Cost Silvicultural Model for Production Forest in Aceh Province, Indonesia

Mahyuddin, Abubakar Karim, Sugianto, Ashabul Anhar

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 519-531 | DOI: 10.11118/actaun.2021.047  

Production forest is a forestry area used to produce forest products through Business Permit for Timber Forest Products Utilization (locally known as IUPHHK). Today, the main problems in the production forest industry management system are that the developed silvicultural system is still high in cost, and the mechanism of forest supervision and maintenance does not involve the forest communities. Therefore, it is necessary to make an effective and efficient design of a low-cost silvicultural model for production forests to be implemented in Aceh Province. This research aims to generate a low- cost silvicultural model for production forest in Aceh Province...

Antioxidant Properties of Cocoa (Theobroma cocoa L.) Shell Powder in Fermentation and Immersion Treatments

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(4), 533-541 | DOI: 10.11118/actaun.2021.048  

Cocoa shell is a waste of the cocoa processing industry, containing vitamin D, protein, fat, carbohydrates, and fiber as well as antioxidant compounds such as polyphenols. Fermentation and immersion processes are needed in post-harvest cocoa to create the distinctive taste and flavor of chocolate, as well as to produce cocoa bean shell powder, which is also good quality as a waste utilization. This study aims to determine the effect of fermentation and immersion processes on the antioxidant activity and characteristics of the cocoa bean shell powder (CBS). The research method used a completely randomized design (CRD) method with four treatments e.g....
