Effect of Leventis Foundation Youth Agricultural Empowerment Programme on trainees’ food output in Osun State, Nigeria
No full textThe study assessed the effect of Leventis Foundation Youth Agricultural Empowerment Programme (LFYAEP) on trainees’ food output in Osun State, Nigeria. A total of 248 extrainees of LFYAEP were selected and interviewed in the study area through a
systematic random sampling technique using list of Leventis Foundation Agricultural School, Ilesa ex-trainees between the year 2010 and 2017 as sample frame. Data collected were presented using appropriate descriptive and inferential statistics. The mean age of the respondents was 30.0±6.2 and their farming experience was 7.2±4.4. About
74.7 and 77.6% got information about the empowerment through their community
leaders and media respectively; also, they all participated to better their lot in life. In
addition, there were high knowledge and skill proficiency in all the farm enterprises
engaged in after the empowerment. Furthermore, the respondents recorded increased food output in all the farm enterprises engaged in after the empowerment. The findings revealed that at p< 0.05, respondents’ reasons for participation (χ2 = 31.612) had significant association with their food output. Furthermore, at p< 0.05, farming experience (r = 0.483), age (r = 0.322), years of formal education (r = 0.153), knowledge possessed (r = 0.148) and skill proficiency (r = 0.221) of respondents had significant relationship with their food output. Finally, there was significant difference between food output before and after the empowerment (F = 65.59). The study concludes that there was a significant improvement in the quantity and quality of food produced by the extrainees after the empowerment programme. It was recommended that similar empowerment should be put in place for all youth to enhance productivity

No full textrrigation systems in the eastern part of Moldova have dvanced infrastructure wear and tear.The degradation of the system's infrastructure has had a negative impact on the natural and human environment. The research carried out highlighted the negative influence of the absence of maintenance and repair works of the irrigation system on the site environment.The most active polluting factors are represented by the transport of alluvium in canals and pipes, the development of vegetation in the locationof the pumping stations, the soil pollution with the noxious substances from the irrigation water, etc.The state of the environment within the irrigation system causes a human and landscape discomfort
Particularităţile palinologice şi potenţialul germinativ al polenului de Hyacinthus orientalis L.
No full textPalynology is a field of research on pollen and plant spores.Pollen research provides phylogenetic evidence in plant systematics. In this study are reported the main palynological features of a genotype known in the culture of ornamental plants, namely Hyacinthus orientalis.Respective palynological determinations concerned: shape, color of pollen grains, ornamentation of exine, size of pollen grains, number of germination pores/pollen grain. In connection with these determinations, the germination potential was tested on nutrient mediums with different carbohydrate compositions. In this regard, the effects of sucrose and glucose in different concentrations on pollen germination rates were investigated. Hyacinthus orientalis pollen has been shown to prefer 15% sucrose, when percentage of germinated grains was 95%, a percentage that is maintained for the next 96 hours. Glucose were suboptimal for pollen of this genotype. The results of this experiment provide useful information in taxonomy of genus Hyacinthus and in ornamental plant breeding
The most valuable grapevine varieties for wine established by analytical hierarchical process for a sustainable viticulture in Danube terraces viticultural region
No full textIn order to promote a durable viticulture, an analytical hierarchical process (AHP) have been done to identify the most
valuable grapevine varieties for wine in the Danube Terraces Viticultural Region. The grapevine varieties taken into the
study are dedicated to white wine (Crâmpoșie, Riesling of Rhin, Fetească albă), red and rosé wine (Negru of Drăgășani,
Pinot noir, Cabernet franc, Merlot, Sangioveze). The AHP exercise was based on pairwise comparisons of 11 subjective
criteria (including knowledge for recognition, market potential, “celebrity” of the product on the market, biotic and
abiotic threats), and expert’s opinion. According to the results, the grapevine varieties with the highest potential for this
region were selected as being Fetească albă, Merlot and Pinot Noir, also zoned for this wine region. Although the wine
production of the area consists mostly of table wines, among which the dominant ones are those for white wines, two
varieties for red wines and one for white wine were selected. The analyses were obtained by using the Expert Choice
Desktop software (v. 11.5.1683). Taken into consideration the pedoclimatic characteristics of the region and the
climatic changes situation, the behaviour of the three ranked grapevine varieties to different stress factors have been
discussed. In the Danube Terraces conditions, the drought sensitivity of some grapevine varieties requires the reduction
of water stress by irrigation. In areas with heavily eroded land on the slopes or fronts of terraces, it is recommended to
use some rootstocks (Kobber 5BB, 41-B, SO4-4) to avoid the appearance of ferro-calcium chlorosis produced by the
excessive presence of carbonate
Researches regarding the influence of the technological factors on the biology of the species and seed yields at Carthamus tinctorius L. In A.R.D.S. Secuieni
No full textThe paper aims to highlight the influence of technological factors on the biology of the species and seed production at Carthamus tinctorius L. (safflower). The research were carried out in 2019, in the experimental field of A.R.D.S. Secuieni. Due to the higher temperatures from the third epoch and the precipitations recorded in the sowing to
emergence period, the plants had a faster evolution. It was necessary 117 days from sowing to harvesting the seeds, the sum of the accumulated temperatures was 2241.9 ° C and the precipitation amounted to 230.7 mm. Under the conditions of A.R.D.S. Secuieni, at the first sowing epoch, there was an increase in production of 156 kg/ha compared to the control of the experience. The interaction of the studied factors influenced the seed production, obtaining the highest seed production at the sown variant at 70 cm between rows and 25 cm between plants per row (1688 kg/ha)

Out of the total of 10 species of parasites identified at pheasant, 4 species (Prosthogonimus ovatus, Syngamus tracheia, Ascaridia galli, Heterakis gallinarum), are also specific for quail, 5 species are specific for
guineafowl (Prosthogonimus ovatus, Capillaria annulata, Syngamidia tracheia, Heterakis gallinarum), 5 species are specific for chickens (Prosthogonimus ovatus, Syngamus tracheia, Ascaridia galli, Heterakis gallinarum, Trichostrongylus tenuis) and only 2 species are specific for turkeys (Ascaridia galli, Heterakis gallinarum). Out of the total of 10 species of parasites identified at quails, 4 species (Prosthogonimus ovatus, Syngamus tracheia, Ascaridia galli, Heterakis gallinarum) are also common at pheasants, 4 species are specific at guineafowl (Prosthogonimus ovatus, Syngamus tracheia, Ascaridia galli, Heter), 5 species are specific for chickens (Prosthogonimus ovatus, Syngamus
tracheia, Ascaridia galli, Heterakis gallinarum, Raillietina tetragona) and 4 species are specific for turkeys (Capillaria caudinflata, Ascaridia galli, Heterakis gallinarum, Raillietina echinobothrida). Out of the total of 7 species of parasites identified at guineafowl, 4 species (Prosthogonimus ovatus, Syngamus tracheia, Ascaridia galli, Heterakis gallinarum) are common at pheasants, quails and chickens, and 3 species are specific for turkeys (Ascaridia galli, Heterakis gallinarum, Raillietina tetragonal)
Toxicity of Deltamethrin to Zebrafish Gonads Revealed by Cellular Biomarkers
No full textDeltamethrin is responsible for health and reproduction problems both in mammals and aquatic organisms. In this study, zebrafish adults were exposed for 15 days to 0.25, 0.5, 1, and 2 μg L−1 non-lethal concentrations of deltamethrin, knowing that is used worldwide on agricultural crops. We investigated the chronic effects of deltamethrin on gonads by histopathological examination, immunohistochemistry, and immunofluorescence using biomarkers for apoptosis (anti-p53, anti-H2A.XS139ph antibodies, and TUNEL assay), oxidative stress (anti-Cox4i1 antibody) and proliferation (anti-PCNA antibody). Among the histopathological changes, the apoptotic response was elevated in ovary and testis of deltamethrin exposed groups as it was seen in the IHC and IF for p53, H2A.XS139ph, and confirmed by TUNEL assay. These were observed in the case of all studied concentrations compared with the control group. Thereby, the gonadal tissue exhibited an up-regulated activity of this cell-death signaling markers, while the proliferation marker (PCNA) increased in the ovary due to its presence not only in primary growth and cortical-alveolar stage follicles but also in atretic follicles, meanwhile decreased notably in the testis. Cox4i1, a mitochondrial marker, decreased both in ovary and testis during deltamethrin treatment, probably inhibited by the overproduction of the free radicals after pesticide exposure
