Men, Dinh Thi
DOI: https://doi.org/10.56293/IJASR.2022.5425
ABSTRACT: This study aims to study English teachers' perceptions of classroom management necessary skills at a
high school in Quang Ninh. An exploratory research design was applied in this study. Eight English teachers were
purposively chosen to participate in the study. A structured questionnaire was used to collect necessary data about
the teachers' perceptions of classroom management skills and the use of those skills in managing their English
classes. The informal interview was then conducted to obtain in-depth information about teachers' perceptions and
reasons for what they did in the class. The collected data was analysed quantitatively and qualitatively and presented
in tables and translation scripts. Results of the study revealed that English teachers at a high school in Quang Ninh
province have a positive perception of their roles in managing the learning process of their students. They all played
8 dominant roles in managing their class. (Controller, Organizer, Assessor, Prompter, Participant, Resource, Tutor,
and Observer). In addition, in order to play the roles through classroom activities more effectively, besides having a
deep understanding of the teacher's roles, the ways of acting their roles, and knowing how to apply them
appropriately

DOI: https://doi.org/10.56293/IJASR.2022.5426
ABSTRACT: Hazardous materials that need to be watched out for are exposure to lead (Pb) in solder wire from the
used battery recycling industry. Pb can cause health problems for workers and the community around the high risk
industry. Exposure occurs through inhalation, ingestion or skin because Pb is a multi-media pollutant. Abnormal
levels of Pb in the blood have a risk of 1,783 times, can reach toxic levels and cause disturbances in the soft tissues
of the liver, characterized by increased levels of SGOT and SGPT in the blood. The purpose of this study was to
determine the relationship between blood lead levels and SGOT & SGPT levels in residents around the used battery
recycling industry. The number of research samples as many as 40 respondents through the analytical method of
observational cross-sectional design approach. Sampling was done by non-probability sampling with purposed
sampling technique. The results showed that Pb levels reached 695.90 ug/L exceeds the value of the biological
exposure index (IPB). There is a relationship between blood lead levels and blood SGOT& SGPT levels (p = 0.003)
and (p = 0.000) with a strong positive relationship (r = 0.460)and (r = 0.526). The conclusion is that there is a
relationship between blood lead levels and SGOT & SGPT levels in residents around the used battery recycling
industry and the greater the blood Pb level, the higher the SGOT & SGPT levels.

ABSTRACT: The rapid growth of the population of Bamako inducing an increase in car traffic and
of motorcycles in the agglomeration has led to a significant increase in air pollution. For
diagnose this phenomenon, an inventory of this atmospheric pollution with measurements of the quality of
ambient air at a number of points, as well as traffic counts were made. This study aims to
objective of characterizing the different sources of emissions in order to model the health impact of air quality
ambient for the different scenarios. Its purpose is to propose an action plan to limit emissions to
from the simulation of the evolution of emissions and ambient air quality by 2015 and 2020 with and
without an action plan. The results of the two air quality measurement campaigns show levels of
concentration lower or substantially equal between those of July 2019 than those of the 2009 data.
PM10 concentration recorded indicates a zone of significant overrun compared to the guide values of
concentrations set by the WHO. Analysis of the evaluation of emissions and their health impact over the horizons
2015 and 2020 shows that volatile organic compound and dust pollution will become unacceptable if
nothing is done. The number of benzene-related cancers will increase to 686 cases and the increase in mortality due to
dust at an average proportion of 38.7%. Proposals have been made on improving the living environment,
fuel quality and vehicle fleet.

ABSTRACT: The sun's light is an unewable, renewable source of energy that is unaffected by environmental factors
like noise and pollution. It is easily obtainable from the Earth's petroleum resources, natural gas, and other
nonrenewable energy sources like coal. There were several stages of evolution in the composition of solar cells from
one generation to the next. The silicon used in the early solar cells was largely produced as single crystals on silicon
chips. Furthermore, advances in thin films the dye and organic solar cells improved the cell's efficiency. The inability
to choose the best solar cell for a particular place is essentially what prevents advancement

DOI: https://doi.org/10.56293/IJASR.2022.5429
ABSTRACT: Women farmers in Nigeria particularly in rural areas have always worked and their labour contributes a
key role in the survival of millions of Nigeria families. Most rural women in Nigeria are the invisible farmers and
they form the backbone of rural development, however more than half of Nigeria's food is produced by female
farmers. These studies analyze the profitability and efficiency of tomato production among female farmers in
Ibadan North Local Government Area of Oyo State. The study specifically described the socioeconomic
characteristics of the respondents, determines the technical efficiency and factors affecting technical efficiency and
lastly estimated the profitability of tomato production in the study area.
The study revealed that the female tomato farmers were adult and active, most of the farmers were literate, majority
had 5 household sizes and less and most of the female tomato farmers had little experience in tomato production.
The study also revealed that farm size, capital and labour were the factors that significantly affected tomato
production of the respondents while the variables representing household size and number years spent in school
affected the Inefficiency of farmers in the study area. The mean technical efficiency was found to be 0.97 (or 97%)
which implied that, on the average, the farmers were 97% technically efficient; hence their observed output was
about 3% less than the maximum frontier output.
Furthermore, the total variable cost, total fixed cost and the total cost were found to be ₦61,680.00, ₦32.488.89
and ₦94,168.89 respectively. Also the total revenue, gross margin and profit were found to be ₦253,522.20,
₦191,842.20 and ₦159,353.31 respectively. This indicates that tomato production is profitable in the study area.

DOI: https://doi.org/10.56293/IJASR.2022.5430
ABSTRACT: This study intended to assess the water quality of a River in terms of the abiotic factors and bacterial
analysis. Sampling stations were established through transect sampling. The abiotic factors or the physico-chemical
parameters recorded from the river were found to be very supportive for the total well-being of the water and the
aquatic organisms alike: water velocity (0.36 m/s) is smooth and temperature (23.18 oC) is on average that make
both parameters "essential" to support the life cycle of organisms known to indicate a good water quality; pH level
(7.14) is average/"satisfactory" for a fresh water; and turbidity (17.95 NTU) is rated as excellent. The bacterial
analysis indicated that the water of Dahilayan River, Manolo Fortich, Bukidnon, Phils. contains bacteria that make
the water not potable. It is then concluded that the Dahilayan River is still in good condition as it projects onstandard-levels of abiotic factors or the physico-chemical parameters, however the streams' bacterial content makes
the water not potable.

AN EXPLORATORY STUDY OF PREDICTORS OF COMPLIANCE WITH
OCCUPATIONAL HEALTH AND SAFETY GUIDELINES IN EMERGING BUSINESS
ENTERPRISES
Peter Letadi Mphai, Zeleke Worku and Mammo Muchie
DOI: https://doi.org/10.56293/IJASR.2022.5431
ABSTRACT: A key operational and strategic priority of the City of Tshwane is to ensure satisfactory compliance with
occupational health and safety guidelines in business enterprises that are formally registered as well as businesses
that operate informally without being formally registered. Formal registration enables businesses to benefit from
assistance programmes that are meant for small, micro and medium-sized business enterprises. A report published
by the Statistics South Africa (2021) shows that 55.6% of South African businesses are formally registered. A study
conducted by Mphai (2022) shows that the main shortcomings in terms of ensuring satisfactory compliance are
poor awareness and inability to enforce applicable guidelines and municipal bylaws in business enterprises. As part
of the survey, quantitative information was collected from 406 businesses in and around the City of Tshwane. The
level of compliance with occupational health and safety guidelines was measured by using a set of 24 standard
indicators of compliance with occupational health and safety that are used by the WHO and ILO. The level of
compliance in businesses that were chosen for the survey was 53%. By WHO and ILO standards, this level of
compliance is inadequate. Recommendations are made with a view to improve the current level of compliance.

CLASSICAL, GC-MS AND FT-IR CHARACTERIZATION OFAZANZA GARCKEANASEED OIL
Myina, O. M.*; Abdullahi, A. A.and Ogundiran, O. A
DOI: https://doi.org/10.56293/IJASR.2022.5432
ABSTRACT: The pharmaceutical and wellness industries have recourse to nature for guidance, inspiration and as a
source of novel compounds to produce new consumer products.Seed oils provide renewable sources of high-value
fatty acids forthese industries. This work was carried out to establish the oil content ofAzanzagarckeana (A.
garckeana) seeds (from Tula village, KaltungoLocal Government Area of Gombe State, Nigeria) and the composition
of the oil. Soxhlet extraction of A. garckeana seed oil (AGSO) was carried out at 75oC for 3 h using petroleum ether
(60-80 oC) and 42.2 % oil yield was obtained. Thus, A. garckeana seed is a renewable source of seed oil comparable
to palm kernel. The AGSO was analyzed for moisture/volatiles (4.0 %), specific gravity (0.926 at 25 oC), refractive
index (1.4694 at 25 oC), saponification value (189.0 mg/g), iodine value (80.0 mg I2/g), peroxide value (5.6 meq/kg),
acid value (0.56 mg/g) and free fatty acid (0.28 mg/g) using classical standard (AOCS) methods. GC-MS analysis of
theAGSO revealed its major fatty acids as: linoleic acid (30.0 %), palmitic acid (13.0 %), oleic acid (2.5 %), stearic
acid (1.0 %), sterculic acid (0.25 %) and myristic acid (0.19 %). Other major components of the AGSO are n-hexane
(43.6 %) and 5-bromo-2,4-bis(methylthio)-pyrimidine (7.8 %). By these results, AGSO is a nondrying oil with
omega-6 polyunsaturated fatty acids (PUFA) dominating its fatty acid profile. This suggests that AGSO has the
potential to lower risk of coronary heart disease (CHD), reduce total and low-density lipoprotein (LDL) cholesterol
as well as correct insulin sensitivity and blood pressure if used as a dietary replacement for saturated fatty acids.
AGSO also presents as a veritable renewable source for n-hexane and a potentially bioactivepyrimidine derivative.
Thus, AGSO has the potential of a natural source for nutraceuticals and vital daily supplements or therapeutic
remedy in nutrition and/or healthcare.

DOI: https://doi.org/10.56293/IJASR.2022.5433
ABSTRACT: This study focuses on the lateritic gravels of N'DOUCI whose physical properties do not meet the
specifications for their use as a road base. Thus, for its use in road construction, a partial substitution of cement by
granite powder has been made. Several tests (particle size analysis, chemical analysis, CBR and proctor tests,
Atterberg limits, etc.) were carried out to verify the geotechnical and mechanical characteristics of the new material.
This study showed that the addition of granite powder in place of cement improved the material properties, i.e.
optimum dry density, CBR. The results show that the optimum dry density is 1.95% with a moisture content of
12%. Overall, the results obtained are satisfactory and show that a quantity of 2% cement for 6% granite powder is
required for a base course material in road construction. However, it would be useful to use the proportions of 4%
cement to 4% granite powder.

Sartrean Freedom and his Idea of Concrete Liberalism
1 Daniel Shifare Weldeyohannes, 2 Dr. Sabas Kimani, 3 Rev. Dr. John Muhenda
DOI: https://doi.org/10.56293/IJASR.2022.5435
ABSTRACT: In the philosophical arena, freedom has been tackled beginning from the ancient period. It has been
tackled by political philosophers like Thomas Hobbes, John Lock, Jean Jacques Rousseau, and John Swart Mill.
They dealt with it from a political perspective as having political ends and means. In the contemporary world,
freedom is seen not only from a political view but also from a philosophical and conceptual understanding as
fundamental to politics as well. This article through descriptive and analytical methods shows the relevance of
Sartrean freedom to society. It shows the ontological understanding of freedom as a principle for practical freedom.
Ontological freedom was seen as basic for ontic (material) freedom and so for social freedom as well. However,
Sartre’s understanding of concrete liberalism was not enough for social freedom. Therefore, the article concludes
that there should be trans-socio-political freedom.

A Review on Reclamation and Management Practices of Wind Erosion and Salt - Affected Soils of Sudan
Motasim Hyder Abdelwahab
DOI: https://doi.org/10.56293/IJASR.2022.5436
ABSTRACT: Wind erosion and salt–affected soils are predominant desertification processes in Sudan, particularly in
the northern part, and have adverse impacts on agricultural lands in the arid and semi-arid lands characterized by
erratic rainfall, high temperature, high wind velocity and consequent high rates of evapotranspiration. The main
objective of this paper is to present research review on combating, control, reclamation and management practices
in areas affected by wind erosion and salt - affected soils. The study showed that the principal measures for
controlling wind erosion depends on minimizing certain conditions that can be accelerated wind erosivity (winds ≥
5.4 m/sec) and vice versa maximizing soil erodibility by creation a suitable condition for generate of non–erodible
soil particles (NEP) versus soil surface detachment and transport by wind. Wind erosion research requires high
financial support, thus this cost should be borne by government. The strategy of management practices of saltaffected soils aimed to sustain a level of salinity tolerable to the cultivated crops through good manages to water and
crop. Assessment and mapping of wind erosion and salt - affected soils is urgent need to determine the inherent risk
in the affected areas included in investment map of agricultural land capabilities of the country. Encourage studies
on stabilizing soil particles by various natural or synthetic cementing and flocculation materials which are friendly to
soil environment to increase NEP on the soil surface. Practical programs on reclamation of salt–affected soils
should be included in national development programs and national strategy for scientific research in the State.

THE EFFECT OF INTENSE COMPETITION FROM WELL ESTABLISHED BUSINESSES ON POORLY RESOURCED RETAIL BUSINESSES
Ignitious Moraba and Zeleke Worku
DOI: https://doi.org/10.56293/IJASR.2022.5437
ABSTRACT: Data was gathered from 62 traditional retail businesses at Tembisa Township by using a questionnaire to
assess and evaluate the extent to which traditional retail businesses are affected by large scale shopping malls. A
review of the literature shows that traditional retail businesses used to supply goods, products and services to people
who live and work at Tembisa Township before the mid-1990s. Since then, large retailers and shopping malls have
opened up shops at Tembisa Township, thereby competing against traditional small scale retail businesses. A
significant market share has since been lost to large retailers and shopping malls by traditional small retailers and
businesses. The results showed that some of the traditional retail businesses had managed to survive by using
innovative marketing and networking techniques. The key attributes of resilient businesses were keeping very close
working relationships with their historical customers, comparing selling prices on a daily basis, actively encouraging
customers to keep supporting their businesses, opening up their shops earlier than 9:00 AM each day, staying very
late in the evening at work, working extended hours, the use of social media platforms, selling on credit and
ordering merchandise in bulk and on credit.

*1 Whyte Asukwo Akpan, 2 Usunguruag Enefiok Okon., 3 E.J. Awaka-Ama
DOI: https://doi.org/10.56293/IJASR.2022.5438
ABSTRACT: Sound proof generating sets are normally associated with higher power output and it is costly. This is not
commonly found in small generating sets as there are often acquired by low income earners and yet they desire the
some comfort. This research focuses on the development of a new composite muffler for small generating sets. The
design combined the principles of reactive and active noise reduction approach. The newly designed muffler was
compared with an existing design and its performance evaluated. Performance tests show an improvement in terms
of insertion loss and transmission loss and a reduction in back pressure build-up in the generating set. The average
overall efficiency of the existing muffler is 43.28% whereas that of the newly designed composite muffler
is 55.83%.The designed composite muffler provides the gasoline generating set with an additional noise reduction
(attenuation) of 17.33 dB, reduced back pressure build-up of 3.6 kPa and improvement of 12.09% overall engine
efficiency.

M. R. B. Alencar, W. L. A. Neves and B. A. Souza
DOI: https://doi.org/10.56293/IJASR.2022.5439
ABSTRACT: The installed capacity generation and the load distribution effects on the optimal location and sizing of
photovoltaic generators in the distribution network are analyzed in this article. A genetic algorithm estimates the
optimal location and sizing of photovoltaic generators. The calculation of the feeder annual energy losses, which are
the objective function of the optimization problem, is performed by the backward/forward method. The complete
feeder's annual active load duration curve is segmented into three levels. It is assumed that the load curves in all
buses are identical to the feeder and the irradiance and ambient temperature are invariant to the average value for
each load level. The analysis is based on scenarios created for a 69-bus test system.

DOI: https://doi.org/10.56293/IJASR.2022.5441
ABSTRACT: This study investigates and reports petrographic characteristics, geochemical features and the processes of
formation of rocks in Ikogosi, southwestern Nigeria. Eighteen (18) rock samples (six quartzite, six migmatite gneiss
and six schists) were collected and subjected to optical study. Ten (10) representative samples (six quartzite, three
schist and one migmatite gneiss) were evaluated for major elements composition using Energy Dispersive X-Ray
Fluorescence (ED-XRF). Petrographic evaluation revealed quartz, feldspar, muscovite, biotite, hornblende,
pyroxene and opaque are dominant mineral constituents in quartzite and schist while migmatite gneiss contains the
same set of minerals but without opaque constituents. Quartz forms a dominant constituent in quartzite and
migmatite gneiss but as subordinate mineral in the schist. The feldspars are mainly plagioclase with albite twinning,
associated microcline has characteristic crosshatched twinning. Chemical investigation reveals the rock units are
generally siliceous. Three oxides (SiO2, Al2O3 and Fe2O3) constitute 85–90% of the bulk chemical composition of
the rocks. SiO2 constituent as applied in rock classification indicates the quartzite is unequivocally felsic, migmatite
is intermediate while the schist is mafic to ultramafic. K2O versus SiO2 variation plot revealed that the quartzite
and schist are tholeiitic while the migmatite gneiss is shoshonitic. TiO2 versus SiO2 variation diagram depicts
igneous antecedent.

business activities such as restaurants, cafeterias, spaza shops, newspaper shops, clothing, textile, footwear, hair
dresser’s shops, tour operators, bus and taxi ranks, hotels and entertainment centres. Braamfontein has retailers
from all over the world. A survey was conducted by gathering retail trade data from 586 entrepreneurs in
Braamfontein working in footwear and textile retail businesses to determine predictors of profitability. The study
found that 406 of the 586 SMMEs in the study (69.28%) were profitable, whereas the remaining 180 of the 586
SMMEs in the study (30.72%) were not profitable. Results obtained from factor analysis and ordered logit
regression analysis showed that profitability was significantly influenced by 3 variables of the study. These 3
predictor variables of study were the level of satisfaction of employees with the style of business leadership in the
business, use of social media for networking and marketing merchandise to customers, and the ability to check the
quality of services rendered to customers by employees of the business.

DOI: https://doi.org/10.56293/IJASR.2022.5443
ABSTRACT: In this project, finite abelian groups with some theoretical and algebraic structures are considered. The
order of each group is factorized completely with factor of higher multiplicity where necessary. This unique
factorization will allow for a way of building new groups and understanding a given group better. Essentially, it
provides a way of relating the given group to the direct products of some of its subgroups. Finally, it also reveals
how a group of a finite order is isomorphically related to one of the direct products satisfying certain relatively
prime condition.
Illustrative examples are considered with a demonstration of the applicability of the project

Assessment of Natural Radioactivity and Radiological Hazard indices in Cassava Cultivated in
Oil Producing Area, Rivers State, Nigeria
Irunkwor, T. C 1, Abanjo, N 2 and Ogboi, K. C 3
DOI: https://doi.org/10.56293/IJASR.2022.5444
ABSTRACT: The natural radioactivity and radiological hazard indices associated with the consumption of cassava
crops grown in five communities with history of oil spillage, gas flaring, oil bunkering activities and operation of
illegal artisanal oil refining in Rivers State was assessed and measured with gamma ray spectroscopy. Five samples
of cassava crop and five samples of soil were collected from the five communities. The results obtained were used
to evaluate the soil-to-cassava transfer factor (TF) due to ingestion of cassava crops/staple foods by inhabitants in
the area. The mean activity of soil samples ranged from 17.77±4.20Bq/kg to 31.84±3.20Bq/kg for 238U,
22.75±3.30Bq/kg to 33.82±4.70Bq/kg for 232Th and 110.44±9.60Bq/kg to 483.15±18.20Bq/kg for 40K, and is
within permissible standard, but is higher than the mean activity in the control. The mean activity of cassava
samples ranged from 6.50±1.30Bq/kg to 29.70±6.20Bq/kg for 238U, 5.80±2.20Bq/kg to 16.50±6.80Bq/kg for
232Th and 383.20±28.10Bq/kg to 482.30±35.80Bq/kg for 40K and is found higher than those of the control
samples, and the international permissible limits. The study revealed that although some of the radiological hazard
indices in the cassava samples were below the allowable standards, the estimated committed annual effective dose
and excess lifetime cancer risk due to ingestion of cassava crops/staple foods is respectively over 2.9 times and 5.9
times higher than the international permissible limit of 0.29mSv/y. The rate of radionuclides transferred from soilto-cassava has mean TF of 232Th < 238U <40K. It is therefore recommended that a community based awareness
programme on the issue of environmental contamination from extraneous activities, its health impacts due to
consumption of cassava crops/staple foods in the area and possible prevention be organized by the various
government agencies involved in environmental protection.

Risk Assessment of Natural Radionuclides in Surface and Ground Water of Oil and Gas
Producing Communities, Rivers State, Nigeria
Irunkwor, T. C 1, Omoruyi, C. I 2 and Ogboi, K. C 3
DOI: https://doi.org/10.56293/IJASR.2022.5445
ABSTRACT: The natural radioactivity and radiological health risk associated with the use of water from hand-dug
wells, tap/boreholes and river/creeks in three communities with history of oil spillage, gas flaring, oil bunkering and
operation of illegal artisanal oil refining activities in Rivers State, Nigeria was here assessed and measured with
gamma ray spectroscopy. The results showed that the mean activity concentration of water samples for hand-dug
well water ranged from 11.94±1.12 to 12.77± 1.12Bq/l for 238U, 7.88±1.05 to 9.20±1.82Bq/l for 232Th and
13.50±0.62 to 20.13±3.88Bq/l for 40K. The mean activity concentration for the tap/borehole water ranged from
2.42±0.45Bq/l to 5.31±0.80Bq/l for 238U, 1.02±1.01 to 2.24±0.90Bq/l for 232Th and 9.71±5.04 to 11.73±3.77Bq/l
for 40K. The 238U, 232Th and 40K activity concentrations in the river/creek waters ranged respectively from
6.81±0.80 to 8.82±1.20Bq/l, 4.25±0.65 to 9.52±1.16Bq/l and 25.01±3.23 to 30.03±1.96Bq/l. These values are
higher than the mean activity concentrations of the 3 radionuclides in the control samples and some are higher than
the international permissible standards. Results further revealed that there was statistically significant difference at
p<0.05 in the mean variations of the activity concentrations of natural radionuclides in the water supply sources
within the three communities and the control. The committed annual effective dose and excess lifetime cancer risks
are radiologically higher than the permissible limits. Therefore, children and adults in the three communities are
susceptible to high dose related diseases and have high chances of contracting cancer when water is ingested from
the three water supply sources since the committed annual effective dose and excess lifetime cancer risk are
respectively over 1.16 times and 8 times higher than the UNSCEAR and USEPA international permissible limits of
0.29mSv/y and 1x10-4 mSv/y.

IMPLEMENTATION OF PROSPECTIVE CIVIL SERVANTS AS PUBLIC SERVICES TO
MOVE FASTER, RISE UP STRONGER IN THE DIGITAL ERA TOWARDS SPECIFIC,
MEASURABLE, ACHIEVABLE, RELEVANT, AND TIME-BOUND CIVIL SERVANTS
Monica Henny Sudaryati
DOI: https://doi.org/10.56293/IJASR.2022.5446
ABSTRACT: Basic Training for Civil Servant Candidates is held to develop competencies that are carried out in an
integrated manner. Procurement of Candidates for Civil Servants at the Ministry of Religion to obtain State Civil
Apparatus who have personal characteristics as public service providers, with skills, expertise, and behavior in
accordance with the demands of the position for the advancement of the institution. The digital era has brought
about changes in prospective Civil Servants to become State Civil Apparatuses that are specific, measurable,
achievable, relevant, and time-bound (SMART)
This research was conducted at the Jakarta Religious Education and Training Center. The purpose of this study is to
determine the implementation of Civil Servant Candidates who become public servants to move faster and rise
stronger in the digital era towards a State Civil Apparatus that is Specific, Measurable, Achievable, Relevant, And
Time-Bound. This research method is a qualitative approach. Data collection techniques used are observation,
interviews and documentation.
The results indicate that prospective civil servants already have positions in accordance with the required
qualifications and have moved faster in line with the mastery of technology they already have and the speed with
which they capture information in the digital era. Increasing self-competence has implications for public servants to
build and develop professionalism and SMART of State Civil Apparatus.

DOI: https://doi.org/10.56293/IJASR.2022.5447
ABSTRACT: The man must eat to live, from his food, he must find the necessary nutrients to satisfy the needs of his
body which must grow and develop its immunities so that it stays alive. For this purpose, no type of food can be
neglected. Vegetables and fruits, which have only played a secondary role in the human diet, the health situation in
the world puts them at the forefront of planetary news and demonstrates all their nutritional importance.

Assessment of residual effects of organic manures (Tithonia diversifolia and bat-guano) on maize
cultivation in the Ngandajika region in central DR Congo
Nkongolo Mulambwila Michel
DOI: https://doi.org/10.56293/IJASR.2022.5448
ABSTRACT: It has been clearly established that organic matter provides crops with not only nutrients, although in a
lower proportion compared to mineral fertilizers, it releases them slowly and gradually. In addition, it also improves
the other characteristics of the soil and thus further conditions the fertility of the soil. Consequently, the study of
organic manure should not only be limited to the analysis of its effects on the development and yield of crops, it
should also extend to the examination of its impact on the maintenance or increasing soil fertility.
