ABSTRACT

Heavy metal contamination of soil and plants is a worldwide concern. Copșa Mică in Romania is one of the areas in the country known to have a high level of pollution. Even if metallurgical activities have been reduced or stopped the soil is still polluted. This study aimed to estimate the bioaccumulation of heavy metals (Cd, Pb, Zn and Cu) in soil from garlic bulbs (Allium sativum L.) from individual gardens in the Copșa Mică polluted area, Romania. The bioaccumulation of heavy metals in garlic bulbs was estimated based on a data set collected from 44 individual gardens. The value of the linear correlation coefficient between the total cadmium content in the soil and that in the plant was significantly different from zero, indicating a close correlation between the two variables (r = 0.775***). In addition, for zinc (r = 0.649***) and lead (r = 0.423**), simple power-type regressions were found to be best for estimating the bioaccumulation of these elements in garlic bulbs. Only for copper, the value of the linear correlation coefficient was not significantly different from zero (r = 0.274ns), indicating that the estimation of copper accumulation in garlic cannot be described by simple power-type regressions. The results of this study are important for estimating the accumulation of heavy metals in garlic bulbs (head), which are often consumed by the population.

ABSTRACT

Cowpea (Vigna unguiculata (L.) Walp.), one of the most important leguminous crops, is widely cultivated throughout the tropics, especially in the savanna regions of the world. However, its seed is attacked by several insect pests both in the field and in storage, especially the cowpea weevil. To control weevils, most farmers have adopted the use of chemical insecticides, but these insecticides come with health and environmental problems, and as a result, there is advocacy for the use of bio-pesticides in the form of tree botanicals. This study was conducted to assess the effects of neem leaf powder (NLP), moringa leaf powder (MLP), and camphor against the cowpea weevils (Callosobruchus maculatus) in a completely randomized design. Six treatments were used and allocated as T1 (control), T2 (4g of camphor), T3 (25g of NLP only), T4 (25g of MLP only) T5 (50g of NLP only) and T6 (50g of MLP). The treatments were replicated three times. The parameters studied were the numbers of damaged and undamaged seeds, the numbers of dead and live weevils, and the taste of cowpea seeds. The treatments effectively protected the cowpea seeds during the storage period of eight weeks. The preservation of cowpea seeds given by camphor was significantly different from the other treatments. However, there was no significant difference (p >0.05) between the neem and moringa leaf powders treatments. The use of moringa and neem leaf powders might be adopted by cowpea farmers in sub-Saharan Africa as alternative, cheap, and available sources of biopesticides to use as chemical insecticides. If cowpea seeds are to be stored for consumption purposes, moringa leaf powder should be used since most respondents preferred the taste of cowpea seeds treated with moringa. Additionally, the storage duration of eight weeks was too short for the experiment, so further studies can be carried out for an extended period of more than eight weeks.

ABSTRACT

The plankton communities are important source of food for the aquatic organisms, and if any undesirable changes in aquatic environment may affect plankton diversity and density. Therefore, assessment of planktonic communities in the freshwater ecosystems is essential because they serve as bio-indicators of water quality parameters. Hence, the present research was focused to evaluate the freshwater phytoplankton and zooplankton diversity and their abundance in Valankulam lake (Lat. 10.59° N and Long.76.57° E), at Coimbatore city, Tamil Nadu, India. Results from the study revealed that a total of 77 species of phytoplankton and zooplankton were recorded, under 37 families and 46 genera. In addition to that, a total of 43 phytoplankton species were recorded under 25 families and 30 genera, (which includes; 15 species of Cyanophyceae, 17 species of Chlorophyceae, 08 species of Bacillariophyceae, 03 species of Euglenophyceae). and a total of 34 species of zooplankton were recorded under 12 families and 17 genera, (which includes 13 species of Rotifera, 09 species of Cladocera, 08 species of Copepoda and 04 species of Ostracoda). The maximum plankton diversity was observed during the monsoon season and the minimum in the summer season. Results from study revealed the ecological status of the lake is categorized as moderately polluted due to the presence of municipal waste and industrial discharges into the lake water. Therefore, the assessment of planktonic communities in water bodies will be useful to monitor and maintain the water quality parameters and wealth of aquatic biota in the aquatic ecosystem.

ABSTRACT

Wine soils from the country’s main vineyards contain 0.05-0.25 g total per 100 g soil, 0.9-20 mg /100 g soil and 6.5-36 mg /100 g soil. The amount of fertiliser that the plant will use – the degree of use – depends on the age of the stumps, the type of rootstock and the planned production. Acting as a factor for the intensification of production, mineral fertilisers, used as a complement to organic fertilisation, contribute not only to maintaining and increasing soil fertility but also to the quantitative and qualitative growth of production. Since the natural reserves of nutrients are limited, the application of natural and mineral fertilisers, scientifically based and differentiated according to the concrete pedoclimatic conditions, is of particular importance from an ecological and economic point of view. The research undertaken highlighted that the use of chemical fertilisers, in different dosages and ratios, favourably influenced the accumulation of sugar in the must for both varieties, with values that were between 178 g/L sugars for the Aligote variety and 170.7 g/L for Feteasca alba. The- relationship positively influenced the accumulation of sugars for both varieties, 177.4 g/L sugars for the Aligote variety and 171.3 g/L for Feteasca alba.

ABSTRACT

This study focuses on monitoring the sexual behaviours of male and female goats (Capra hircus) at each stage of mounting and observing sexual reflexes and related peculiarities. The ethological behaviours of females and males were observed twice per day, between 6:00 and 8:00 a.m. and between 19:00 and 21:00 p.m, and the anatomical parts of females in estrus were inspected and scanned. Each mount was recorded using a video camera. A digital timer was also used to record the stages of sexual act (prelude and copulation). The sexual behaviours of a common breed of goats reared in non-professional holdings was studied in August, September and October 2020 and 2021. Sexual behaviour was observed in a total of 24 goats, 5 males, aged 3–8 years, and 19 females, aged 1–10 years, raised in a rural area (Priponesti) in Galati County. The data gathered provide details of the sexual behavior of this species, supplementing the information currently available. The most numerous mounts were carried out by the 4-year-old buck (M1 male) with 7 out of 20, representing 35% of the total mounts observed. The mount was characterized by very high duration of courtship (average 98%) compared to the true mounting (average 2%) (p < 0.05). The postlude behavioural manifestations observed were bucks continuing to inspect the anogenital area of the female, wagging their tongues while the goats expressed a characteristic bleat.

ABSTRACT

This study aimed to investigate if canine staphylococci isolates could develop tolerance to chlorhexidine digluconate after long-term exposure. Staphylococci (Staphylococcus pseudintermedius and coagulase-negative staphylococci, methicillin-susceptible and methicillin-resistant), with and without genotypic chlorhexidine resistance, were investigated for phenotypic chlorhexidine tolerance by determining the MBC (minimal bactericidal concentration) at various time points. The testing was performed as follows: determination of MBC for 30 minutes and 24 hours (MBC 24h-1); exposure of isolates for seven days to concentrations of chlorhexidine equal to 1/2 MBC 24h-1; determination of MBC for 24 h after the first week (MBC 24h-2); exposure of isolates for seven days to concentrations of chlorhexidine equal to 1/2 MBC 24h-2 and rest in Mueller–Hinton broth for seven days; determination of MBC for 24 h after the second week (MBC 24h-3). The MBC for 30 minutes ranged between 16–32 µg/ml compared to the MBC 24h-1 which was between 1–8 µg/ml. The MBCs for 24 h dropped from 8 µg/ml to 0.5 µg/ml for isolate 1, from 2 µg/ml to1 µg/ml for isolate 6 and from 2 µg/ml to 0.5 µg/ml for isolate 8 after being exposed for seven days to concentrations of chlorhexidine equal to 1/2 MBC 24h-1. For one CoNS (coagulase-negative staphylococci), the MBC 24h-2 increased four times from 1 µg/ml (MBC 24h-1) to 4 µg/ml and dropped again to 1 µg/ml after the second week. These results suggest that continuous exposure to chlorhexidine could lead to the selection of chlorhexidine-tolerant staphylococci that could withstand concentrations used during routine decolonisation procedures.

ABSTRACT

Climate change is one of the greatest challenges mankind has ever faced and could lead to potentially devastating global problems, with a need for urgent mitigation and adaptation. Agriculture, especially livestock farming, is a major driver of climate change through its contribution to the total emissions of greenhouse gases (GHGs). The dairy sector has been identified as an important source of GHG emissions, mainly via carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O). In this study, total CO₂ equivalent (CO₂e) emissions were assessed from a dairy farm (65 dairy cows) located in Romania using the Cool Farm Tool calculator (CFT). We specifically aimed to calculate: (1) the total CO₂ equivalent (CO₂e) and CO₂e per kg FPCM (fat- and protein-corrected milk); (2) methane emissions from enteric fermentation; (3) GHGs resulting from feeding practices; (4) GHGs from manure management; and (5) a simulation of two different scenarios and their impact on GHG emissions. Our results showed annual GHG emissions of 553,170 kg CO₂e, almost half of which were released through enteric fermentation. Lactating cows were the major contributor to total GHG emissions, while heifers released the lowest emissions. The two scenarios simulated in this study showed that both the changes made in dairy diet composition and livestock manure management could result in lower GHG emissions. These results confirm the importance and utility of the CFT for the quantification of GHG emissions in dairy farms and its important role as a decision support tool to guide the adoption of good agricultural practices.

ABSTRACT

The role of agriculture is an extremely important one because it provides the necessary production of foods for the population and, at the same time, represents a source of raw materials for different processing industries. For a growing population, agriculture has been the main source of agri-food products that must ensure the food security of the population. Compared to other states of Europe, Romania is one of the European countries with the most favourable soil and climate conditions for agriculture. The last world crises, from the crisis in 2008 to the pandemic crisis in 2020-2021, and especially to the current conflict between Russia and the Ukraine, have brought up the issue of food self-sufficiency. During the current period, it is important to know what production can be obtained in Romanian agriculture and if it can provide the food necessary for the population. An analysis regarding the dynamics of the cultivated areas and production of the main crops in Romania has been carried out, for each of its 8 development regions. The data, collected from different sources, were analysed using different methods. The research results highlight, for example, that Romania can easily achieve the self-sufficiency stage for most agricultural products of plant origin. In conclusion, natural resources, as well as the existence of a certain material base in Romanian agriculture, can ensure the increase of agricultural production, the satisfaction of the food needs of the population, as well as a certain availability for export.

ABSTRACT

The increase in the concentration of greenhouse gases in the Earth’s atmosphere, especially that of CO2, is a major concern because it is the main source leading to global warming, and its impact on climate change is still widely studied. The intensity and frequency of drought and flooding increase due to the change in climate, which has a negative impact on crop productivity and food security. The aim of this paper was to demonstrate the role of corn in carbon sequestration based on plant biomass and soil organic carbon accumulation. We presented the main factors that contribute to carbon sequestration and concrete examples regarding the capacity of corn hybrids created at National Agricultural Research and Development Institute (NARDI) Fundulea, as well as aspects regarding the importance of soil tillage and fertilisation. In contrast to genotypes in which this ratio was lower, maize genotypes that demonstrated a rise in the root:stem ratio under drought stress conditions produced more biomass, suggesting that the roots of these genotypes can grow at water potentials where stem growth is inhibited, which are attributes that also prove their good potential for carbon sequestration under climate change conditions. The organic carbon content in the superficial soil layer decreased with the intensification of the degree of soil mobilisation (9.95% when working the soil with the chisel, 17.91% for ploughing), but fertilisation had a beneficial effect. The biomass was higher than that of the unfertilised soil. This means that a higher carbon input has a positive influence on the carbon stock in the soil.

ABSTRACT

This paper aimed to investigate and analyse the diametric and spatial distribution of Prunus avium populations in Tunisia. This study may help us document better information about the ecological processes and its functioning. Dendrometric and ecological data were collected on four square plots of an area of 1 ha each within two forests, Tabarka and Ain Draham, in northwest Tunisia. The results presented in this work show that P. avium individuals present a diametrical structure in the form of an “inverted J” translated by the dominance of the seedlings compared to the other classes. The analysis of the spatial distribution shows that wild cherry is identified by its aggregates and variable size (approximately 5 m and 20 m). It is coherent with the mode of vegetative propagation by suckering and the dispersal of fruits by birds.
This investigation opens insight into other species to ensure good sustainable management of natural resources.
