The effect of commercial organic and inorganic fertilizers and rhizobium inoculation on yield and yield components of faba bean (Vicia Faba L.) and pea (Pisumsativum L.)
No full textThis research was conducted to determine the effect of organic and inorganic fertilizers and bacteria inoculation on yield and its components on pea and faba bean in Dicle
University Agricultural Faculty, Diyarbakir, Turkey, during 2018 and 2019 growing seasons. The experiment was laid out following a split-plot in completely randomized block design,
with three replications. Fertilization treatments and cultivars were designed as main and sub factors, respectively. Data on plant height, plant biomass, pod weight, seed yield per plant, number of pods and number of seeds per plant, biological yield, seed yield and 100-seed weight were recorded at harvest. Number of nodules and nodule dry weight were
record in flowering time. The effect of inorganic nitrogen, organic fertilizers and bacteria inoculation on grain yield, seed yield per plant, biological yield was significant at both pea and faba bean. Inorganic fertilizer (urea) was increased the grain yield (2147 kg/ha) and
biological yield (4956 kg/ha) in faba bean, but close to control (2080 kg/ha and 4690 kg/ha). Organic-1, Organic-2 and bacteria treatments were decrease the grain yield and biological yield on pea and faba bean, and this decrease on pea was almost half over control. The effect of treatments on number of nodules per plant on pea and faba bean was significant. The highest number of nodules per plant on pea was in bacteria inoculation (125.9) and control (121.5), and differences among nitrogen (109.1), Organic-1 (97.3) and Organic-2 (109.3) treatments was no significant
Influenţa mărimii tuberobulbilor asupra fenologiei şi valorii ornamentale la Gladiolus byzantinus
Get PDFThe behavior in culture of the Gladiolus byzantinus species, in the
ecological conditions of the NE area of Romania, has been studied for several
years at the University of Agricultural Sciences and Veterinary Medicine Iaşi.
In this paper we determined the way in which G. byzantinus corms influence the
growth and development of plants, respectively their decorative value. The
establishment of experimental crops it was made in November 2019, using
corms with different mass: > 10g (V1), 7-9 g (V2) and <7g (V3). Observations
and determinations performed in 2020 showed that from corms with a mass >
10g (V1) were obtained plants with the highest number of shoots, flower stems
and flowers. At the variants from the smaller corms, respectively V2 and V3, the
results were inferior, except for the height of the floral stem. From a
phenological point of view, the beginning in vegetation, the formation of floral
stems, the onset and duration of flowering, were to the advantage of the V1
variant
Studies and researches on the possibilities to cultivate vegetable plants in pots and containers
No full textPreliminary investigations on prevalence of ESBL-production Escherichia coli strains in swine from Botoșani County
No full textAdministration of antimicrobials to food-producing animals increases the risk of higher antimicrobial resistance in
normal intestinal flora. The present preliminary study was conducted to investigate the presence of extended spectrum
beta-lactamase (ESBL)-producing Escherichia coli strains in healthy swine from Botoșani County. During 2016-2018,
a total of 87 samples of luminal contents of gut sections (cecal) were collected and tested. Fifty-one (51,72%) E. coli
isolates were identified as ESBL-producing strains. These preliminary results reflect the selective pressure, caused by
intense and less prudent use of the antimicrobials in swine production in our country. Moreover, commensal E. coli can
be a reservoir for antimicrobial resistance genes, which can be transferred to pathogenic bacteria. Therefore, resistance
genes transferring from farm to fork represent a public health emerging danger by the potential of producing difficultto-
treat pathogens
Evaluation of the Antifungal Activity of Gold–Chitosan and Carbon Nanoparticles on Fusarium oxysporum
No full textNanoparticles are implemented in different biotechnological fields, and there is interest in their use in plant biology. Nanotechnology can help overcome the persistent limitations of using conventional fungicides in the management of plant diseases, contributing to a safer environment. Hence, this study is focused on evaluating the behavior of nanoparticles on two different strains of Fusarium oxysporum, which have a wide-ranging occurrence in tomato production and account for important economic losses. Fusarium oxysporum is an ascomycetous fungus that is well-known as a soilborne plant pathogen, adapted to any soil type, and it lives in different forms on organic materials. Gold–chitosan and carbon nanoparticles were suspended in potato dextrose agar growth media, and their antifungal activity was evaluated at 1, 3, 5, and 7 days after incubation by measuring the diameter of fungal colonies. The results showed that the nanoparticles have antifungal properties against F. oxysporum, the fungal colony growth diameter being reduced. Likewise, it was observed that the colony diameter was smaller when the nanoparticle concentration increased. However, in the case of one F. oxysporum strain, the highest nanoparticle concentration applied during the experiment’s execution was not able to completely inhibit fungal growth
The behavior of some soybean varieties in the pedoclimatic conditions from the Center of Moldavia
No full textSoybeans is an important source of protein because the amount of protein in a hectare of soybeans is higher than in any
other crop. It has a wide range of uses, and it can be used in many areas: for food production, for food and as fuel.
Considering the growing interest, in recent years, for this crop, at the ARDS Secuieni a number of ten soybean varieties
have been experimented, Carla TD, Larisa, Caro TD, Ilinca TD, Bia TD, Ada TD, Teo TD, Miruna TD, Felicia TD,
Onix, creations of the Agricultural Research and Development Station Turda, in order to establish their adaptability to
the pedoclimatic conditions of the area. On average, the factors studied greatly influenced soybean production, which
varied widely, from 2687 kg/ha, to Felicia TD variety to 3409 kg/ha to Larisa variety. Regarding the correlation
between soybean production and the protein production obtained, it is observed that there is a direct correlation, the
correlation coefficients calculated being statistically assured and interpreted as very significant
Photosynthetic capacity in Amorpha fruticosa, Acer negundo, Ailanthus altissima and Eleagnus angustifolia, the invasive plants vs. native plant in Danube Delta biosphere reserve areas
No full textThe purpose of this study is to analyse gas- exchange parameters and chlorophylls synthesis in order to establish the
photosynthetic capacity of some ligneous plants with invasive behaviour in comparison with native trees in areas of
Danube Delta. The investigation was carried nearly of Razelm Lake (Beștepe hill), a xerophilous coastal meadow with
clumps of trees (fallow vine plantation) and in three other plots (Plaur I, Plaur II and Pătlăgeanca) situated along Chilia
branch. Photosynthesis rate registered lower values in Amorpha fruticosa (3.53 µmol m-2
-s
-1
) in comparison with Populus
alba, young plantation (33 µmol m-2
-s
-1
), lower value in Ailanthus altissima (13.5 µmol m-2
-s
-1
) in comparison with
Fraxinus ornus (14.54 µmol m-2
-s
-1
), comparable values in Acer negundo with Amorpha fruticosa (close to 3.5 µmol m2
-s
-1
). Generally, the investigated invasive plant registered a lower respiration rate than non-invasive/native species.
Transpiration was direct proportional with photosynthesis rate and with stomatal conductance. Photo-assimilatory
pigments represented by chlorophyll a, chlorophyll b and carotenoids as total registered in Ailanthus altissima being by
approximative 1.4 times higher in comparison with Crataegus monogyna and Fraxinus ornus (Beștepe station), by 1.5
times higher in Amorpha fruticosa than Acer negundo in ruderal area (Plaur I) and having close values at Amorpha
fruticosa and Populus alba in riparian plantation (Plaur II). Analysis of photosynthetic capacity revealed the competition
strategy between invasive plant and native or even among invasive, especially co-dominant species such as Amorpha
fruticosa vs. Populus alba, Amorpha fruticosa vs. Acer negundo, Ailanthus altissima vs. Fraxinus ornus and Eleagnus
angustifolia against Salix alba in studied areas
Cytopathological diagnostic in canine lymphoma
No full textLymphomas are tumors that may be frequently diagnosed in dogs. The main suspicion for this neoplasic disease arises
when lymphnodes become enlarged without the existence of any obvious antigenic stimulation. Fine needle aspiration
from enlarged lymphnodes with the preparation of cytological slides allows for an early and relatively precise diagnostic
in lymphoma cases. We used this technique, along with the May Grunwald Giemsa staining method to search for
cytological and nuclear abnormalities that might indicate the evolution of a lymphoma in dogs that presented with
enlarged lymphnodes. We found a constant mixture of medium sized and large lymphocytes, multinucleated cells,
anisokaryosis, various nuclear shapes (multiple indentations), multiple visible nucleoli, variable cytoplasmic/nuclear
ratios and cytoplasmatic chromatic properties (basophilia, light basophilia). Also, the mitotic index measured per 5 HPF
fields (x400) was sometimes a strong indicative of malignancy. All of the cases diagnosed with lymphoma based on
cytopathological examination were later confirmed through histopathological examination. This suggests that this
simple and fast technique that is applicable also in small animal practices may be used to diagnose lymphomas in dogs
with a relative high accuracy
Response to poliovulatory (POV) treatment, by ultrasound in Suffolk breed
No full textThis study was done on a batch of Suffolk beef sheep, acclimatized in Romania.. The success of an ET protocol in sheep
depends on many factors, but in the end, what matters is the number of embryos obtained. Embryo recovery (recovery
rate), after poliovulation (POV), is an essential step in ET. The aim of our experiment was to observe the ovarian reaction
(follicles –F, and corpora lutea-CL) to the treatment of Suffolk sheep polyovulation, The aim of our experiment was to
observe the ovarian reaction to the treatment of Suffolk sheep POV. A number of 3 Suffolk sheep were poliovulated at
the reproductive season, using P4-FSH-PGF protocol. The POV method was based on the administration of sponges
with intravaginal progesterone 12 days, followed by 500 IU FSH: LHp in decreasing doses in the last 4 days, and a PGF
on day 11. The poliovulatory ovarian response was monitored by transectal ultrasound, before estrus was detected, and
on the day 7. The ovulatory response following POV treatment was assessed by CL counting. In two out of three sheep,
CL was identified, despite the fact that they all had follicular growth, in sheep no. 2, no dehiscence occurred. The total
number of formations observed was 26 CL. The distribution of CL between the two right and left ovaries, in the three
cases examined was thus 8 CL on the right ovary and 7 CL on the left (in sheep 1), no CL in sheep 2 and 6/5 in sheep
no. 3. The POV response to FSH in the Suffolk breed was an average of 8.6 F/sheep of the developed follicles. Our goal
was in fact to follow the ovarian dynamics in these meat breeds, in order to apply the best treatment schemes, for
successfully apply embryo transfer
Soil phosphorus dynamics of sweet potato-based cropping system in a rainforest region of Nigeria
No full textTo guard against soil
phosphorus (P) toxicity in tuber
production and have optimum tuber yield
at lesser cost of P-fertilization, better
understanding of the dynamics of
phosphorus release in sandy loamy soil is
inevitable. Therefore, this work was carried
out to investigate the trend of P-release
from time of application to its optimum
release and its effect on sweet potato
growth and tuber production. To achieve
this, a 5-week incubation study under
laboratory conditions was carried out to
study P-release dynamics using different
P sources. Similar experiment was
conducted on the field using the same
P sources and application rate to monitor
the influence P-release rate on sweet
potato production. Data on number of
leaves, vine length, tuber yield, soil
extractable phosphorus and phosphorus
uptake of the plants were taken.
Relationships between P-uptake and tuber
yield, number of leaves, vine length were
also established. It was found that the
trend of phosphorus release was a sigmoid
shape. Leaf production and vine length
were improved by P-application, while
yield was suppressed. It is recommended
that P-fertilizer should not be applied to
the soil at short intervals to avoid nutrient
toxicity
