Salinity stress tolerance of three cowpea cultivars in a Southern guinea savannah ecological zone of Nigeria
To combat the problem of
food scarcity and insecurity in areas
affected by salinity, crop varieties that are
tolerant to the stressful conditions should
be selected and used. Therefore, this study
was carried out to investigate and know
the effects of salinity stress on growth and
yield of three cowpea cultivars to select
the best salinity tolerant cultivar for
optimum yield production. To achieve
this, three separate experiments were
concurrently carried out using ITIOK-298-15, IFE BROWN and
SAMPEA 11 cowpea cultivars in the
glass house of the Faculty of Agriculture,
University of Ilorin, Nigeria. The salinity
levels tested in each of the cultivars were
0mM (the control), 50mM, 100mM and
200mM sodium chloride (NaCl). The
imposition of salinity stress was for a
period of two weeks at maturity because
this stage is the most sensitive stage for
any crop grown under any environmental
stress. The experiments were laid out in
randomized complete block design
(RCBD) with four replications. Data
collection was centred on root length,
plant height, number of leaves, leaf area,
dry mass, final yield, chlorophyll content
of leaves, crude protein and crude fat
contents. From this work, it was found
that 200mM NaCl decreased the final
yield by 51% in ITIOK-298-15, 73% in
IFE BROWN and 100% in SAMPEA-11
compared to the control. Furthermore,
100mM NaCl reduced crude protein
contents of the leaves by 6% in ITIOK-
298-15, 10% in IFE BROWN and 17% in
SAMPEA-11 compared to the control.
From the above results, it was found that
ITIOK-298-15 was the most tolerant
cultivar while SAMPEA-11 was the most
susceptible cultivar to salinity stress. It is,
therefore, recommended (subject to
further confirmation) that ITIOK-298-15
cultivar, which is the most promising
cultivar of the three cultivars
experimented, be used in cowpea
production in saline environments of the
Southern Guinea savannah ecological
areas of Nigeria
Biodegradarea coloranţilor sintetici de către tulpini bacteriene izolate din sol
In present study, 19 bacterial strains were isolated from different type of soil (Danube –Delta Biosphere Reserve), molecularly identified (16S rDNA sequencing), and tested for their textile dye biodegradation potential and tolerance level to heavy metals and high salinity. The strains Pseudomonas sp., Bacillus sp. andThalassospira sp. were found to degrade ˃ 72.64% RO16 dye, but only Pseudomonas putida removed (56% decolorization) the RB4 dye.Also, was found a good tolerance to salinity (8% NaCl) in case of Pseudoarthrobacter sp., Enterobacter sp., Thalassospira sp.,Bacillus sp., and Pseudomonas sp. strains. Most of the bacterial strains tolerated 70 ppm of cromium (Cr6); only two strains, Cupriavidus respiraculi and Pseudomonas putida showed maximum tolerance to 70 ppm cadmium (Cd2+); all strains of Pseudomonas sp.showed tolerance to 100 ppm lead (Pb2+). The selected strains could be used in bioremediation process of industrial dye waste waters
The nutritional impact on bacterial plate, the development and treatment of tartar in cats
The accumulation of bacterial plaque on the teeth, the mineralization of these and the change of the oral cavities pH are the result of the interactions between different components of the oral environment and bacterial flora. These interactions will determine the type of bacterial populations that will occur on every situs thus forming the dental plaque. The bacterial plaque can be characterized based on localization, bacteriological composition and the effect on the oral cavity. Tartar is the main factor, which determines different grades of gingivitis, infections, and paradental diseases leading to tooth loss at cats. A thorough prevention and treatment plan will primarily consist of a well-balanced alimentation with a gross structure of feed. Potassium phosphate has a crucial role in the efficiency of the therapeutic protocols capacity to eliminate bacterial plaque, accounting for a reduction of 32% of calcium accumulations thus considerably slowing the mineralization or calcification of bacterial plaque at cats. This study looked at the impact that certain foods have on the development of plaque and tartar formation, furthermore it analyzed the tartar reduction after implementing a therapeutic diet. We also did a microbiologic examination of the saliva and the deposits at the level of the enamel. It was also observed that cats that were fed dry and moist food in equal amounts, were more prone to develop the above mentioned deposits
Micro-credit applications as a struggle against women poverty: a case study of Isparta province, Turkey
The micro-credit applications used as a struggle against women poverty in Isparta province were examined in this study. The main material of the study was comprised of original data acquired via face to face interviews with 212 women micro-credit users in the city of Isparta. It was determined based on the study results that 62.26% of the women
micro-credit users were between the ages of 30-49, 54.25% had low education levels (primary school), 87.74% were married with an average family size of 3.76 people. It was observed that 87.26% of the women had social security and that the monthly family income of 40.09% varied between 1001-1500 TL. Majority of the women (58.49%) indicated that they used the micro-credit for developing their already existing businesses. It was set forth that the women used the micro-credit mostly in areas of commerce (43.87%), handwork/embroidery (28.30%) and animal husbandry (19.34%). The women indicated that their social relations and self-confidence increased as a result of the credit. About 80% of the women stated that there was a little increase in their family income after the micro-credit and it was determined that majority of the women (89.62%) want to use micro-credit again. Of the women who participated in the study 68.40% suggested an increase in the amount of credit while 51.89% suggested longer payment periods between two installments
Water stress effect on wheat at different mechanical seeding systems
Judicial water use, as well
as improving water use efficiency in
agriculture is new challenge.
Conservation tillage, as well as
mechanical seeding system, offers various
benefits over intensive tillage system.
Considering this, the study was conducted
to find out the water requirements and
appropriate deficit irrigation schedule of
wheat on different seeding system. This
study consisted of following irrigation
treatments, like I1 = Irrigation at CRI
stage, I2 = Irrigation at CRI and vegetative
stages, I3 = Irrigation at CRI and grain
filling stages and I4 = Irrigation at CRI,
vegetative and grain filling stages on four
mechanical seeding methods, like T1 = Bed planting, T2 = PTOS, T3 = Strip
tillage, and T4 = Zero tillage and laid out
in a split plot design with three
replications. From the result based on the
grain yield and water productivity, bed
planting (T1) and three levels of irrigation
(I4) was found as the best combination for
wheat cultivation. Besides, at water
scarcity area bed planting (T1), with two
irrigation I2 (CRI and vegetative) was the
suitable reduce irrigation scheduling for
wheat cultivation. In different seeding
methods, bed planting was increased yield
about 10.58%, followed by PTOS and
yield was identical in PTOS and ST.
Comparatively, lowest yield was observed
in zero. In irrigation treatment, three
irrigations (I4) was observed, the best
scheduling for wheat on all seeding
system and yield was increased 11.98% in
I4, followed by I2 and lowest yield was
found in I1. The result also revealed that
the soil moisture contribution was
decreased with increased applied water, as
well as number of irrigation
Assessment of combined effect of human feces compost and single superphosphate on the behaviour of wheat production
Application of organic fertilizers in improving soil fertility has become a major factor that has enabled the world to feed billions of people. However, the required quantities of
organic material are enormous, so it becomes necessary to combine different types of fertilizers to feed plants. The effectiveness of human feces compost (HC) alone, as well as in combination with single super phosphate (SSP), was evaluated in the present study. A field experiment was conducted at farmer field located in district Swabi (Pakistan). A total of eight possible treatments combination were arranged in randomized complete block design (RCBD), replicated four times. Two levels of human feces compost (HC), including
control (HC0: control and HC1: 7.5 t ha-1) and four levels of P, as single superphosphate (SSP), including control (P0: control, P1:40 kg ha-1, P2: 60 kg ha-1 and P3: 90 kg ha-1) were utilized in the experiment. Results revealed that among all the treatments, combined application of SSP at 60 kg ha-1 along with 7.5t ha-1 HC significantly improved the growth, as well as the yield parameters of wheat crop. These results allow saving a half of
usually made mineral fertilizer dose for the cultivation of wheat crop. Combined use of HC and SSP were strongly recommended for obtaining maximum wheat yield in the prevailing soil and environmental conditions
Reactivity of mucosa-associated lymphoid tissue (MALT) in pigs that received in food black grapes seed and skin powder
The study was carried out on 20 pigs from the Petrain breed that received powders and skins of black grapes in 1% ratio for 3 months. At the end of the experiment, samples were taken from duodenum, jejunum, ileum, colon, mesenteric ganglia, which were fixed with 10% buffered formalin, included in paraffin, sectioned and stained with HE. Following the examination, there was a diffuse lymphoid infiltration into the lamina propria of the mucous membranes studied, agglomeration of lymph nodes in the submucosa of the jejunum, ileum and colon in pigs from experimental group (EG). lymphoid follicles from mesenteric lymph nodes are larger and more numerous in pigs from EG compared to control group (CG). Polyphenols from black grape powder in this experiment resulted in significant lymphoplasmocyte infiltration into the mucosa, digestive submucosa and mesenteric lymph nodes and increased carcass weight at slaughter by 1.08 Kg compared to LM
Study on European financing in the field of public food and tourism, at the level of Romania
Europe is today the culmination of its development, and European funding is the driving force behind the development of the economy of the Member States. The study aims to break down the economic phenomena related to the absorption of European funds and to analyze their evolution in the Multiannual Financial Frameworks (MFFs) 2007-2013 and
2014-2020. Methodologically, the research included a documentary analysis of some studies, reports, strategic documents and an empirical study based on the sociological investigation in the field of public food and tourism. The paper analyzed the impact of European funding at the level of Romania and the added value of European funds in the
field of public food and tourism. The results of the study highlighted the major impact of European financing on economic development and the increase of the competitiveness of the economic sectors. The MFF 2007 - 2013 contributed to a great extent to the achievement of the proposed objectives. Thus, 9.4 million jobs were created, of
which 42,000 research jobs were created, 0.4 million SME-s were created, access to road networks, railways, water supply increased for about 7 million people. In the current programming period (2014-2020) the European Commission aims to support specific areas such as economic, social and territorial cohesion, competitiveness for growth and jobs, administration, global Europe, sustainable growth; natural resources, security, and citizenship. For the next programming period, 2021 - 2027, the proposed budget amounts to 1.135 billion euros, representing the equivalent of 1.11% of the gross national income of the EU-27. The long-term objectives of the European Union are related to the single market, innovation and the digital sector, cohesion and values, natural resources and environment, migration and border management, security and defense, neighborhood and worldwide, European public administration. The case study conducted in the field of public food and tourism has revealed that although there are still barriers to accessing European funds (legislative, strict conditions imposed by specific guidelines, financial limitations) there is a high openness to the added value brought to the national economy by European funding
Evaluation of different strategies for induction of chilling tolerance in spring maize using moringa leaf extracts
Spring maize is highly sensitive to low temperatures during the early development of seedlings and to high temperatures during its reproductive stage. Different strategies are being used to minimize the adverse effects of temperature extremes. Therefore, a field
experiment was conducted to enhance the performance of spring hybrid maize by seed priming (3% MLE) and transplanting 20 and 30-day-old seedlings. Seed priming with moringa leaf extract (MLE) significantly enhanced stand establishment in both direct sowing and in transplanting, as indicated by the higher emergence percentage, emergence index, and lower time taken to start of emergence and mean emergence time.
Minimum days from sowing to tasseling and silking were found in MLE primed 20-day-old seedlings grown in a nursery. However, all the agronomic parameters increased considerably with MLE priming of 20-day-old seedlings. Thus, MLE priming reduced chilling damage by improving stand establishment, whereas transplanting 20-day-old seedlings further enhanced the agronomic traits, yield, and quality of maize. However, the performance of maize plants from 30-day-old transplanted seedling and direct sowing
was substandard
Metode de creştere a sustenabilităţii urbane prin amenajarea de spaţii verzi în zone industriale
The idea of the present work started from the concept of urban sustainability, which aims at the correct use of all spaces by increasing the areas planted rationally and thus aligning them with the objectives of sustainable development established by Law no. 24 of 2007 and republished on November 10, 2009 (law on the regulation and administration of urban spaces).Starting from the desire to create a relaxing space for the employees of the BMT Aerospace factory which specializes in the development and production of precision gears for the aerospace industry, this work proposes the arrangement of a special green area in the immediate vicinity of the production hall, visible as much from the offices as well as from the work benches. The paper aims to propose the creation of a relaxing space that can easily fall into the category of "industrial green spaces" or "industrial landscape architecture". When removed from the industrial context of the factory, the proposed landscaping falls in the category of park gardens.The plant massifs, the lawn, the water, the wood, the natural stones, were the essential elements for creating the relaxation space,all the more necessary in the short working breaks. As a result, the landscaping presented in this work radically transformed the "green area" inside the factory into a modern, pleasant, comforting space for those to whom it was intended
