Analysis of mycotoxins from cereals and cereal products at Iasi county
No full textCereals and cereal products are of unique importance because they are consumed by millions of people and are
considered, from a nutritional point of view, the main source of carbohydrates for humans and animals. Thus, the
microbiological and mycotoxicological safety of cereals is considered very important both for food and for animal feed.
The paper presents the results of research on the level of mycotoxin contamination of cereals and cereal products in Iasi
County in the 2015-2019 study interval. The aim was to study the incidence of mycotoxins that have a negative
influence on the safety of agri-food products, with subsequent negative impact on human and animal health. The
obtained results were within the maximum allowed limits provided by the specific legislation in force (EC Reg.
1881/2006)
Phomopsis viticola în Podgoria Târnave
No full textPhomopsis viticola, in poorly managed vineyards can produce a lot of
damage due to its year to year infection pattern. In combination with a high spore
reserve from the previous year, this causes reduced grape yields. This study aims to
assess the Phomopsisviticola attack in Târnave vineyards during May-July 2020.
The data (frequency and intensity of the attack) was collected from Crăciunelu de
Jos, and the attack degree (AD) was calculated before and after the treatments for
Saugvinonblanc, Riesling italian, Fetească regală and Traminer roz grapevine
varieties. The AD before the treatment with contact and systemic products was
between 27.80% and 4.10%, after the treatments of the first period (May-June 2020)
the AD was reduced at values between 3.40% and 0.83% and after the treatments of
the second period (June-July 2020) the AD had the values between 9.00% and
12.40%. In conclusion, the fungicide treatments administrated are efficient in
managing Phomopsis viticola in vineyards from Transylvania
Influenţa aplicării unor tratamente chimice asupra atacului produs de larvele speciei Ostrinia nubilalis hbn. La porumbul semănat în diferite epoci în condiţiile din centrul Moldovei
No full textThe Ostrinia nubilalis Hbn. species it is one of the pests specific to the maize crop that produces production losses in terms of quality and quantity. At A.R.D.S. Secuieni, in 2019, researches were conducted regarding the application of chemical treatments to reduce the attack produced by the Ostrinia nubilalis Hbn. larvae to maize sown in different epochs. The results obtained regarding the influence of the interaction between the sowing epoch and the treatments applied on the vegetation on the attack produced by the european corn borer larvae indicated that regardless of the sowing epochs, the variant where it was applied cyantranyliprole had the lowest percentage of attacked plants. The influence of the interaction ofthe two factors (epoch and treatment) also materialized by reducing the average number of holes and larvae/plant, highlighting with the best results, the variants sown in the third epoch, where chemical treatments ensured a good protection of maize plants
Rural households’ perception of vitamin A Biofortified Cassava and its products: implications for food security
No full textThe paper examined the perception of rural households about vitamin A biofortified cassava and its products in Osun State, Nigeria. Multistage sampling procedure was used
to select 50 households’ members. Quantitative data were collected on the respondents’ personal and socioeconomic characteristics, their awareness on vitamin A biofortified cassava, their perception about the crop and its products, as well as the constraints
affecting its acceptability in the study area. Data were described using frequency counts, percentages, means and standard deviation and inferential statistics, like Pearson Product Moment Correlation and Chi-square analyses. Results showed that the respondents had a mean age of 52.62 ± 14.30, while 82% of them were married. 74% of the respondents had heard of Vitamin A bio fortified cassava, 64% had seen it while 44% had planted it with 54% having positive perception towards the crop and its products. Poor transport
facilities (mean = 3.16) and difficulties in getting planting materials (mean = 2.36) ranked highest among the constraints affecting acceptability of the crop in the study area. There exist significant association between the respondents’ marital status and their perception about vitamin A biofortified cassava. It was concluded that majority of the respondents have positive perception towards vitamin A biofortified cassava and its products. It was recommended that extension personnel should create more awareness about the nutritional value of the crop and its products to enhance better food security status among rural households
The yield and quality properties of chickpea seeds (cicer arietinum l.) affected by harvest times
No full textHarvesting of chickpea (Cicer arietinum L.) seeds at right time of maturity is one of the important issues because pod dropping and shattering is a major problem during harvest. Also, the physical properties of chickpea seeds can be affected by harvest time. For this
purpose, a field experiment was carried out to examine the effects of harvest times after physiological maturity on the seed yield per plant and the seed quality properties in chickpea production. The treatments used in the experiment consisted of five harvest times, which chickpea pods were harvested at physiological maturity (H1) and 5, 10, 15,
and 20 days after physiological maturity (H2, H3, H4 and H5, respectively). The
physiological maturity time (R7) was considered as the stage that leaves start to yellow and 50% of pods are yellow. Moisture content, dimension properties, hundred seed weight, true density, bulk density and porosity and seed yield per plant was determined in the study. The results showed that all measured variables were affected by harvest time. The true density and porosity increased with delayed harvest time. But, the other
measured variables decreased when harvest was delayed
Infrared thermal imaging as an innovative approach for early detection infestation of stored product insects in certain stored grains
No full textGrains of field crops, such
as wheat, maize, faba bean and white
bean, are considered strategic food for
humanity worldwide and Egypt.
Unfortunately, percent losses of grains
quantity may reach to 15-30%, as a result
of stored product insect damage, and the
losses increased dramatically in the last
years, as an outcome of quickly
productions of these pests. Experiments
were conducted on infrared thermal
imaging that demonstrate early detection
of infestation by stored product insects in
wheat, maize, broad bean, white bean and
bean grains. The imaging is dependent on
subtle significant differences in
temperature between infested and healthy
grains. Because the thermal imaging data
are digital, computer programs can be
used to analysis differences in
temperature and mining figures explained
for that. Results revealed that the use of
thermal imaging offers an alternative
method to detect an insect infestation.
Data concluded that thermal imaging has
the potential to identify whether the grains
of crops that tested are infested or not, but
is less effective in identifying which
developmental stage is present. Moreover,
it could apply this technique easily on a
large scale in silos, storage, mills and
granaries without negative impact on
quality of stored grains
The influence of conservative tillage systems on physico-chemical properties and yield under a cambic chernozem from Northeastern part of Romania
Get PDFThe long-term experiment was carried out during 2005-2018, with samples collected on the experimental
farm of the University of Agricultural Sciences and Veterinary Medicine in the city of Iasi (47º07` N latitude,
27º30` E longitude). The soil under investigation is classified as Cambic Chernozem (WRB) with a clay-loamy
texture. Initial physical characteristics of the soil on 0-20 cm depth were: bulk density 1.33 g.cm-3, pH (1:2.5)
6.23, clay 364.2 g.kg-1, silt 263.2 g.kg-1, loam 372.6 g.kg-1, humus 2.95%. In the last 5 years a continuous maize
cropping system was used. The tillage treatments included: (1) No-till: direct drilling in untilled soil with a disc
drill without previous removal of residues, using a FABIMAG FG01 seeder (NT); (2) a reduced system using a
chisel at 22-25 cm depth, after harvest without overturning the furrow (RT); (3) moldboard ploughing after
harvest to a soil depth of 28-30 cm (CT). The crumbled and loosened soil was turned over and thereby residues
were fully incorporated into the soil. After the harvest of pre-crop, stubble breaking (disking to the depth
10 cm) was used. Seedbed preparation was applied using a compactor after chisel and conventional tillage.
In spring the weeds were suppressed by total herbicides before seeding. Crop-specific fertilization was
performed according to good agricultural practice. Combine harvest was performed in October (between 5th
and 28th) using a Wintersteiger Delta Plot Combine. Tillage systems affected soil penetration resistance (PR)
under maize crop only for certain soil depths. At 0-5 cm depth, the highest value (0.78 MPa) was recorded on
no-till system, whilst in the case of the other two variants the values ranged from 0.56 to 0.61 MPa. In CT
variant at 30-40 cm, we noticed a compacted layer (2.54 MPa) indicating the existence of hardpan
Germination potential and pollen tube growth in Galanthus nivalis L.
No full textThe present research studies the pollen biology of snowdrop (Galanthus nivalis L.), from the point of view of pollen’s germinating potential and length growth of pollen tubes at two temperatures: 18 °C and 4 °C. The germination was conducted “in vitro” on nutritive mediums containing different concentrations of sucrose (0, 5, 10, 15, 20, 25, 40, 50, 70, 100%). The pollen germination was optimum (more than 90 %) on nutritive mediums containing 15 % and 20 % sucrose, at both studied temperatures, after 24 h. In parallel with germination potential, the adaptation of male gametophytes to the two temperatures was analyzed. The longest pollen tubes were formed on 10–25% sucrose mediums at 18 °C and on 10–15% sucrose mediums at 4 °C, and they were maintained also after 120 h since pollen inoculation. For these concentrations, the pollen tube length was similar at both temperatures. In conclusion, 18 °C is suitable for long tubes formation using a largest range of sucrose concentration than 4 °C. In fact, in most plant species, low temperatures not only inhibit pollen tube growth, but also induce flowers abortion. Present results bring new evidences that the snowdrop’s male gametophyte is genetically settled to have a normal development at low temperatures. The optimal germination rate and pollen tube growth at 4 °C highlight the vernal character of the pollen of G. nivalis
