Agronomic and economic efficiency of the waste use from the production of alcoholic beverages on cambic chernozem
No full textNowadays, the environment ecological status in the Republic of Moldova is deplorable in most natural and
anthropogenic ecosystems. Wastes from the alcoholic beverages production is often stored chaotically presenting a
major danger to the environment soil, water, air, flora and fauna. There is no waste processing and recycling company
in the country. This waste contains a significant amount of biophilic elements necessary for the nutrition of agricultural
plants and the increase of organic matter in the soil. About 100 thousand tons of waste is accumulated annually in the
Republic of Moldova. Waste from the production of alcoholic beverages contains 28 thousand tons of organic matter,
180 tons of nitrogen, 80 tons of phosphorus and 260 tons of potassium. For this purpose, two field experiments were
organized at the Technological-Experimental Station "Codru", Codru commune, Chisinau municipality, where the
residues from the production of alcoholic beverages were studied: wine yeasts and vinasse (waste from wine
production), distillers grains marc (waste from the production of rectified ethyl alcohol) on soil fertility and plant
productivity. Research conducted in 2012-2019 showed that fertilizing the soil with cereal marc led to increased
productivity of field crops. The increase in production on average is 868-1223 kg/ha of cereal units (30-42%) compared
to the non-fertilized version with marc. Fertilization with waste from the production of alcoholic beverages increases on
average over 9 years, the content of organic matter by 0.18-0.37% (4800-10000 kg/ha), mobile phosphorus by 0.3-1.0
mg/100 g soil (8.1-27.0 kg/ha), exchangeable potassium with 10-13 mg/100 g soil (230-300 kg/ha) for variants
fertilized with waste. There was an increase in Sauvignon grape production of 0.9-2.3 t/ha (8-21%) on average for 9
years for wine waste variants. Wastes from the production of alcoholic beverages, applied to the soil as organic
fertilizer have a significant economic effect, can be recovered and reintegrated into viticulture and phytotechnic sectors
Toleranţa la seceta atmosferică a unor plante dendrologice şi modalităţi de implementare în spaţiile verzi urbane şi periurbane
Get PDFThe impact of climate change increasingly depends on the measures and
how affected areas, especially urban ones, manage to adapt by improving urban
plans, increasing areas with green spaces, and adapting infrastructure to encourage
the use of means of non-polluting transportation. But in the case of dendrological
plants, atmospheric drought and pedological drought affect the normal development
of vital processes due to cell dehydration, which in the short term leads to wilting of
plants, and in the long term, can even lead to their death. All the properties of plant
tissues to survive stressors are in fact plant resistance. In this sense, in landscaping in
addition to the already known functions (sanitary, utilitarian, decorative), it is
imperative to use resources rationally by proposing the use of dendrological and
floricultural species as adapted to these stressful environmental conditions. This
paper addresses the issues of high drought and its effects on plants, some aspects of
the assortment of dendrological plants with drought tolerance suitable for the Iasi
area and a proposal to implement these studies in the periurban landscape of Iasi by
arranging a square in the peri-urban area of Iasi
Effects of the dietary millet (Panicum Miliaceum) on some quality characteristics of liver, Longissimus dorsi and Semitendinosus muscle on pigs
Get PDFThe purpose of this study was to evaluate the effect of 25% millet (Panicum miliaceum) as
replacement of triticale on some quality characteristics of pig meat. Forty pigs Topigs hybrid
(initial body weight 13.58 ± 0.37 kg) used in the trial for 30 days were assigned into two dietary
treatments: control diet (M) and experimental diet (E, with 25% millet that replaces triticale from M
diet). The pigs were slaughtered (n=3/group) at 81 ± 3 days (final body weight 32 ± 4.5 kg). The
samples were taken from the liver, Longissimus dorsi (LD) and Semitendinosus (ST) muscle and
analyzed for: pH, colour and texture profile. The pH value of the liver and texture profile of all the
tissue samples from E diet were not statistically different comparing to the M diet. Pigs fed E diet
had a significantly increased value of redness a* in the liver (>17%) and in the ST (>45.5%)
compared to M group. The liver yellowness b* was significantly higher (>53%) in the E group
compared to the M group. For all tissue samples, the shear force was significantly affected in group
E compared to the M group. In conclusion, the replacement of triticale with millet could be
recommended for inclusion in pigs diets, without affecting pig meat quality
Epidemiological Study of Canine Babesiosis and Hepatozoonosis in the South of Romania
No full textPurpose: The aim of this study was to evaluate the prevalence and distribution of canine babesiosis and hepatozoonosis in the south of Romania as well as to assess if there are differences in the prevalence between regions in that area.
Methods: Blood samples from 300 dogs from the south of Romania were screened for the presence of piroplasmids by PCR. Positive samples were further tested for the presence of Babesia spp. and Hepatozoon canis. Pearson's chi-square with Yates correction was used to determine if there is statistical difference between infected populations.
Results: Fifty-four percent (163/300) of the dogs were positive for Hepatozoon spp. or piroplasmids. Forty-eight percent (143/300) were infected with H. canis and 9.6% (29/300) were positive to B. canis. Three percent (9/300) of the dogs were co-infected with Babesia spp. and H. canis. The prevalence of H. canis in the south-west of Romania was significantly higher (p < 0.05) than that of three other regions while the prevalence of Babesia spp. infection in the south-east of the country was significantly higher (p < 0.05) compared to its south-west.
Conclusions: A high rate of H. canis infection was found in the stray dog population surveyed with the highest infection rate detected in south-western Romania. Babesia canis was found to pose the highest threat in south-eastern Romania, whereas B. vogeli infection was focused in the same region of high H. canis infection in south-western Romania. These infections should be of important concern to veterinarians and dog owners in Romania
Evoluţia acidităţii totale şi a conţinutului de zaharuri al strugurilor pe parcursul maturării în relaţie cu microclimatul tufei în condiţiile podgoriei Cotnari
No full textHigh temperatures and high values of solar radiation during grape ripening lead to excessive sugar accumulations and low titratable acidity, with negative consequences on the sensory profile of the grapes and wines. The control of these unfavourable developments for the chemical composition of the grapes becomes a base condition for obtaining quality wines in the context of climate change. The research was carried out in 2020, on Tămâioasă românească wine grape variety in the Cotnari wine growing region, during the grape ripening season. The study revealed: positive correlations between the helio-thermal factors and grapes sugar content; negative correlations between the same climatic factors and grapes titratable acidity; and the influence of some cultural practices on grapes chemical composition. The grapes on the west side of the row have accumulated less sugars during ripening: 137.64 g / L on the west side and 145.72 g / L on the east side; grapes acidity on the west side was also more pronounced, with 13.61 g / L tartaric acid compared to 12.69 g / L tartaric acid on the east side. The 6% bentonite film treatment reduced the impact of temperatures and solar radiation on titratable acidity of the grapes, maintaining it by 0.83 g / L tartaric acid higher than the control
Research regarding the influence of genotype x epoch of sowing x distance between rows on seeds yield at Ricinus communis L. (castor bean)
No full textThe researches were organized in 2018-2019 at the Moldoveni Agricultural Society, Neamt County. Analyzing the
influence of the distance between rows at castor bean, it results that at greater distances yield deficits are obtained, so
when the plant nutrition area is increased, the branching is stronger and the yield obtained from the main raceme
decreases, increasing instead the production of secondary racemes. The results obtained on average over the two years
of experimentation show us that the highest production was obtained for the variant sown at 70 cm between rows (1460
kg / ha), which indicates that castor bean responds favorably at this distance. The average productions obtained in the
analyzed period were directly influenced by the experienced technological factors. These varied in limits between 1036
kg / ha (Rivlas x the fourth epoch x 100 cm between rows) to 1650 kg / ha (Christian x the second epoch x 70 cm
between rows)
Effects of complex fertilizer on yield components and yield of some soybean genotypes
No full textFertilization is one of the main economic and health-promoting factors in crop cultivation. Field trials were carried out
in 2019, in the experimental field of Soybean Breeding Laboratory from Agricultural Research and Development
Station in Turda (ARDS Turda), based on a subdivided parcel design with two replications, using plots of 5 m2
. The
biological material used in this study was created at ARDS Turda, 13 semi-early, early and very early soybean
genotypes being evaluated: 7 varieties (Perla, Onix, Felix, Carla, Caro TD, Ada TD, Raluca TD) and 6 perspective lines
(T-161, T- 295, T-165, T-6126, T-6117 and T-166). Fertilization was carried out with NPK 16:16:16 complex fertilizer
applying the following doses: 150 kg/ha, 200 kg/ha, 250 kg/ha and unfertilized (Control). At the end of the growing
season the genotypes were characterized by: plant height (cm), number of pods/plant, number of seeds/plant, seeds
weight/plant (g), TKW (g), yield (kg/ha). The reported data is the average of 10 measurements. Statistical calculations
were accomplished in Excel 2013 (Microsoft, USA) highlighting differences between studied genotypes and applied
doses. The average of the seed/plant had small variations, in this year's conditions; the grain size varied between 122 g
and 162 g and the maximum yield was about 3 to/ha at the dose of 200 kg/ha complex fertilizer
Evaluation of cotton (Gossypium spp.) Germplasm for heat tolerance under normal and late planting time
No full textThe objective of this study was to determine cotton (Gossypium ssp.) germplasm for heat tolerance under normal and late planting time. For this aiming 200 cotton genotypes and five check varieties (Gloria, SG 125, Flash, Ozbek 105 and Candia) were evaluated under two different temperature regimes and experiments were conducted according to the augmented design with four blocks. Field studies were carried out at the GAP International Agricultural Research and Training Center’s experimental area in Diyarbakır, Turkey, in 2016 cotton growing season. In the study heat susceptibility index was used
for discriminate to the genotypes for heat tolerance. Genotypes were classified into four groups based on the heat susceptibility index. The results of this study indicated that five cotton genotypes (TAM 139-17 ELS, CIM-240, Haridost, MNH-990 and AzGR-11835) were in highly heat tolerant, 28 genotypes were found heat tolerant, 56 genotypes were in
the moderately heat tolerant and other 120 genotypes were observed susceptible for heat tolerance. Based on the heat susceptibility index, five cotton genotypes can be used as parent for heat tolerance improvement in the cotton breeding program where high temperature is a limiting factor for seed cotton yield
The helminth fauna of some invasive fishes from various natural and artificial water bodies from the Republic of Moldova
No full textThis paper presents the results of the study of the helminth fauna of invasive fish species from different water bodies from the Republic of Moldova: prussian carp – Carassius gibelio (Bloch, 1782), stone moroko – Pseudorasbora parva (Temminck & Schlegel, 1846), chinese sleeper – Perccottus glenii Dybowski, 1877, pumpkinseed – Lepomis gibbosus (Linnaues, 1758), silver carp – Hypophthalmichthys molitrix (Valenciennes, 1844), bighead carp – Hypophthalmichthys nobilis (Richardson, 1845). As a result of this study 16 species were detected (Dactylogyrus sp., Gyrodactylus sp., Diplozoon paradoxum, Eudiplozoon nipponicum, Phyllodistomum folium, Diplostomum spathaceum, Botriocephalus opsariichthydis, Khawia parva, Paradilepis scolecina, Philometroides sanguinea, Pseudocapillaria tomentosa, Raphidascaris acus, Posthodiplostomum cuticola, Valipora campylancristrota, Ligula intestinalis)
Geographical Variations in Virulence Factors and Antimicrobial Resistance Amongst Staphylococci Isolated From Dogs From the United Kingdom and Romania
No full textThe objective of this study was to compare virulence and resistance factors of
mucosal and cutaneous staphylococci from dogs with pyoderma in the UK and
Romania, two countries with different approaches to antimicrobial use in companion
animals. Staphylococcal isolates (n = 166) identified to the species level as being
Staphylococcus pseudintermedius or coagulase negative (CoNS) were analyzed for their
antimicrobial resistance (AMR) profile and presence of resistance and virulence genes.
Of the investigated isolates, 26 were methicillin-resistant S. pseudintermedius (MRSP),
89 were methicillin-susceptible S. pseudintermedius (MSSP) and 51 were coagulase
negative staphylococci (CoNS). A significantly larger number of isolates originating from
Romania were resistant to clindamycin, tetracycline, and chloramphenicol compared
to the UK isolates (P < 0.05). Resistance to amoxicillin-clavulanic acid, gentamicin,
and trimethoprim-sulphamethoxazole was more evident in UK isolates. Fusidic acid
resistance was common in Staphylococcus spp. isolates from both countries. Most
isolates carried virulence factors associated with siet (exfoliative toxin) and luk (leucocidin)
genes. All MRSP UK isolates exhibited fusidic acid resistance genes whilst this was very
rare in the MRSP isolates from Romania. The chlorhexidine resistance gene qacA/B
was frequently identified in CoNS isolates from the UK (P < 0.001). The current
study documented differences in antimicrobial resistance profiles of Staphylococcus
spp. isolates from dogs in two geographical locations in Europe, which could reflect
differences in antimicrobial prescribing patterns. The study also highlights the need for
further studies and interventions on antimicrobial use, prescribing patterns and AMR
surveillance in companion animals in Romania
