Published: July 2021

Objective To investigate the therapeutic efficacy of hyperthermic intraperitoneal chemotherapy (HIPEC) as consolidation treatment after completing first-line treatment in patients with advanced ovarian cancer.Methods A retrospective chart review was conducted on patients treated at the Comprehensive Gynecologic Cancer Center between January 2014 and 2019. Based on the inclusion criteria, 24 eligible patients who received HIPEC (paclitaxel 175 mg/m2, for 90 minutes, at 42°C) (HIPEC group) as consolidation treatment after terminating the adjuvant chemotherapy were identified. Another 24 patients who met the inclusion criteria and did not receive HIPEC were matched, representing the non-HIPEC group. Disease-free survival (DFS) and overall survival (OS) were examined between the two groups.Results The median DFS was 28.7 and 24.2 months in the HIPEC and non-HIPEC groups, respectively (P=0.688). The 3-year DFS rates in the HIPEC and non-HPEC groups were 39.5% and 32.6%, respectively. However, the median OS was not determined. The 5-year OS rates in the HIPEC and non-HIPEC groups were 86.2% and 81.3%, respectively (P=0.850). One patient developed grade 3 neutropenia. Other patients experienced mild adverse events after HIPEC.Conclusion This study suggests that consolidation HIPEC could not support the survival benefit after completing the first-line treatment for patients with advanced ovarian cancer, although no severe specific safety issues were found. Therefore, randomized trials evaluating consolidation HIPEC for the management of ovarian cancer are warranted.

Authors: Bastemur Sule , Aslan Ayse Esra
Published: July 2021

Objective: The effectiveness of the Social Anxiety Program on Adolescent Twins investigated in this study. Method: The study is a mixed-method study using a one-group pretest-posttest design, together with the qualitative method. First, Intraclass Correlation Coefficient used to find out the concordance and differentiation level of the twins’ social anxiety. Because monozygotic twins’ concordance rate is higher than dizygotic twins, four pair female monozygotic twins aged 17-18 participated in the group. Wilcoxon Single Ranks Test used to analyze the experimental part of the research. Three sessions of focus groups held after the program. Content analysis techniques used as a qualitative analysis. Result: As a result, there was a statistically significant difference between pre/post-program. Since this difference was in favor of initial measurement, the program interpreted as being effective. Themes also supported the quantitative results. Conclusion: Findings obtained from both experimental and qualitative parts discussed. Suggestions provided for future researcher.
The Katateeb Al-Bidoon Initiative: Repurposing the Past to Build a Transformative Future
Authors: Mansoor Abdullah
Published: July 2021

The Katateeb al-Bidoon initiative was an after-school teach-in combined with a series of government protests against the sudden expulsion of stateless Bidoon children from any official Kuwait school. Considered illegal residents, the Bidoon status in Kuwait has deteriorated over the past generation, and their exclusion from Kuwait society is nearly complete. Regardless, many educational activists and teachers still continue to support Bidoon access to education, and the Katateeb al-Bidoon initiative is one example of their work. The name Katateeb refers to the archaic casual school system that was prevalent in Kuwait before the era of oil urbanization. Though its lifespan was one brief semester, from October 2014 to February 2015, a close examination of the initiative provides insight into how an improvised pedagogy based on an educational model from the past can develop beyond expectations and support a transformative future.

Deregulation of a broad range of protein kinases has been linked to the development and growth of cancer cells. Protein kinases are intracellular enzymes that regulate cell growth and proliferation as well as the triggering and regulation of immune responses. Protein kinases are important therapeutic targets in cancer because of their critical role in signalling mechanisms that drive malignant cell characteristics. Intensive efforts in drug research have been made in this area over the last two decades. The current study delves into the catalytic domain of a protein kinase as well as information transfer from the cell’s membrane to internal targets. It also discusses the function of protein kinases in signal transduction and their cellular signalling pathways. Furthermore, it specifically outlines a systematic method to hybrid therapies to solve the issue of protein kinase resistance. The therapeutic use of nitric oxide, as well as other targets such as Phosphoinositide 3-kinases (PI3K), Protein Kinase B (Akt), serine/threonine protein kinase (mTOR), p38 mitogen-activated protein kinases (p38 MAPK), vascular endothelial growth factor receptors (VEGFR), epidermal growth factor receptors (EGFR), and anaplastic lymphoma (ALK) etc., According to the review article, selective therapy has shown high effectiveness in the treatment of advanced cancer, with protein kinase inhibitors being a main focus of the therapy. As a result, the latest review summarized that, the current state of science with the aim of identifying a novel protein kinase inhibitor that may be utilized in the treatment of advanced cancers.
Biotechnological Potentials of Microbe Assisted Eco-Recovery of Crude Oil Impacted Environment

Published: July 2021

Globally, the environment is facing a very challenging situation with constant influx of crude oil and its derivatives due to rapid urbanization and industrialization. The release of this essential energy source has caused tremendous consequences on land, water, groundwater, air and biodiversity. Crude oil is a very complex and variable mixture of thousands of individual compounds that can be degraded with microbes with corresponding enzymatic systems harboring the genes. With advances in biotechnology, bioremediation has become one of the most rapidly developing fields of environmental restoration, utilizing microorganisms to reduce the concentration and toxicity of various chemical pollutants, such as petroleum hydrocarbons, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phthalate esters, nitroaromatic compounds and industrial solvents. Different remediation methods have been introduced and applied with varied degrees of success in terms of reduction in contamination concentration without considering ecotoxicity and restoration of biodiversity. Researchers have now developed methods that consider ecotoxicology, environmental sustainability and ecorestoration in remediation of crude oil impacted sites and they are categorized as biotechnological tools such as bioremediation. The approach involves a natural process of microorganisms with inherent genetic capabilities completely mineralizing/degrading contaminants into innocuous substances. Progressive advances in bioremediation such as the use of genetically engineered microbes have become an improved system for empowering microbes to degrade very complex recalcitrant substances through the modification of rate-limiting steps in the metabolic pathway of hydrocarbon degrading microbes to yield increase in mineralization rates or the development of completely new metabolic pathways incorporated into the bacterial strains for the degradation of highly persistent compounds. Other areas discussed in this chapter include the biosurfactant-enhanced bioremediation, microbial and plant bioremediation (phytoremediation), their mechanism of action and the environmental factors influencing the processes.

Published: July 2021

Seed vitality and vigour are the two most common parameters related to seed quality. It is crucial to have reliable methods and tests for seed quality and seed vigour testing. The standard germination test can be used to predict field emergence, but laboratory seed testing conditions are often in conflict with field conditions. Validated tests for vigour evaluation in legumes are the conductivity test, the accelerated ageing test and the tetrazolium test. Also, other types of vigour tests have been used to solve different problems in the seed sector. The modern approach, the computerised image analysis of legume seeds and sprouts, based on interactive and traditional methods, is a promising alternative for vigour determination.

Published: July 2021

In the 2018-19 growing season, a total of 51 leaves of eggplant plants grown under field conditions were collected randomly from nine private gardens at four different localities in the Province of Vojvodina. Eggplants with nearly 40% of plants showing bright yellow to white mosaic or mottling of leaves were found throughout the inspected fields (gardens). The collected samples were analyzed for the presence of alfalfa mosaic virus (AMV), cucumber mosaic virus (CMV) and potato virus Y (PVY) using commercial double-antibody sandwich (DAS)-ELISA kits. Serological analysis of eggplant samples revealed the presence of AMV in 80.39% collected samples. None of the analyzed samples was positive for CMV and PVY. The virus was successfully mechanically transmitted to test plants including Nicotiana benthamiana, Chenopodium quinoa, C. amaranticolor, as well as eggplant seedlings, confirming the infectious nature of the disease. The presence of AMV in eggplants was further verified by reverse transcription-polymerase chain reaction (RT-PCR) and sequencing, using the primers CP AMV1 and CP AMV2 that amplify part of the coat protein (CP) gene. The phylogenetic analysis showed that Serbian AMV isolates grouped into a separate well-supported group together with AMV isolates from Italy, Croatia and previously characterized isolates from Serbia. To our knowledge, this is the first report of AMV infection of eggplant in Serbia.
Survey of apple collar and rootstock blight in Serbia
Authors: Iličić Renata , Popović Tatjana
Published: July 2021

Apple production in Serbia is characterized by the introduction of new technologies and the establishment of intensive plantations based on modern systems. In intensive apple production systems, sudden and rapid decay of young apple trees exhibiting collar and rootstock blight symptoms in the first few years after planting is becoming a prevalent issue. However, knip or nursery trees with lateral branches (feathers) on rootstock M.9 i.e. oneto five-year old are most seriously affected. Based on a longitudinal survey of young apple plantations in Serbia and the results of pathogen detection and identification using conventional and molecular methods, the plant pathogenic bacterium Erwinia amylovora was found as the causative agent. By increasing the incidence of collar and rootstock blight in young apple trees, E. amylovora is gaining importance as the most destructive disease in apple production. In order to control E. amylovora effectively and apply appropriate control measures, it is necessary to survey the development of lesser-known symptoms caused by this pathogen, which are becoming prevalent in Serbian agroecological conditions.

Published: July 2021

The experiment with drip irrigated pepper was conducted at the Rimski Šančevi experimental field of the Institute of Field and Vegetable Crops in Novi Sad in 2019. The irrigation was scheduled on the basis of the water balance method. Two methods were used to compute the daily evapotranspiration of pepper (ETd): reference evapotranspiration (ETo) and evaporation from an open water surface (Eo). Crop coefficients (kc) and corrective coefficients (k) were used to convert ETo and Eo values into ETd. Kc and k were 0.3-0.4, 0.6-0.7, 0.9-1.1, 0.8-0.9 and 0.4, 0.7, 1.0 and 0.8 for initial stage, crop development, mid season, and late season, respectively. ETo was calculated by the Hargreaves equation. Eo values were measured by a Class-A pan located at a meteorological station near the experimental plot. Irrigation started when readily available water (RAW) in the 0.3 m soil layer was completely absorbed by plants. Differences in crop yield (Y) and irrigation water use efficiency (IWUE) obtained using Eo (42.58 t ha-1, 15.20 kg m-3) and ETo (40.78 t ha-1, 14.56 kg m-3) were not statistically different. Evapotranspiration rate was 364.2 mm and 337.3 mm in Eo and ETo variant, respectively. The fact that the differences in Y and IWUE between different calculations of ETd were not statistically significant indicates that both methods can be recommended for irrigation scheduling programs for pepper in the climatic conditions of the Vojvodina region. However, priority should be given to ETo due to the easy accessibility and reliability of data.
Research on tourists' satisfaction with the gastro offer of Novi Sad
Authors: Krejić Živana , Milićević Snežana
Published: July 2021

Vojvodina has long been known as an area of high-quality and varied food. In this regard, gastro tourism in its capital is one of the most attractive tourism products. That is the reason why our research was conducted in Novi Sad, aimed to examine the satisfaction of domestic and foreign tourists with the gastro offer of this city. The results of the research show that the gastro offer of Novi Sad is an important motive in attracting both domestic and foreign tourists, but that foreign tourists are still more satisfied with it. Further, there are differences in attitudes between male and female tourists, because male tourists show a higher degree of satisfaction with the gastro offer compared to female tourists, while other socio-demographic characteristics (education and age) are not related to the degree of their satisfaction. The results of the research can be useful in the development of future strategies for the development of tourism in Novi Sad and Vojvodina. They can also serve as a model for analysing tourists' satisfaction with other forms of tourism offer.
The impact of human resource management activities on job satisfaction
Authors: Došenović Dragana , Zolak-Poljašević Branka
Published: July 2021

Although there are numerous and various factors that can affect job satisfaction, human resource management has been identified as one of the most important causes of job satisfaction. For this reason, this paper analyses the impact of human resource management and its activities on job satisfaction in various organizations in the Republic of Srpska, with the main goal to investigate and determine the existence and nature of the relationship between human resource management activities, as an independent variable, and job satisfaction, as a dependent variable. In order to analyse the observed relationship, an empirical research was conducted on a sample of 738 employees from 283 organizations from the Republic of Srpska. The research was conducted using a specially created survey questionnaire, and the reliability of the created instrument was calculated using the Cronbach's Alpha coefficient. Based on the results of the research, which were obtained by correlation analysis, the basic hypothesis was confirmed, which proved that human resource management activities have a statistically significant effect on job satisfaction. Also, all additional hypotheses, claiming that individual human resources management activities (recruitment and selection, training, development and rewarding) have a positive effect on job satisfaction, were confirmed.
Mathematical-physical model of solving inventive problems
Authors: Rajić Dušan
Published: July 2021

The spatial-temporal LT-contradiction matrix is an inventology tool that enables exact calculations of certain parameters in an engineering system through mathematical-physical modeling. It objectifies the decision-making process and creates the preconditions to finding an adequate resource (X-element) with a higher probability, and thus to reach a higher degree of ideality solution (HDIS) of an inventive problem as well. Any engineering system that generates an inventive problem can be described using the LT-contradiction matrix. By crossing the appropriate parameters in the LT-contradiction matrix, with the help of the differential geometry of the tensor, a qualitative-quantitative analysis and calculation of relevant degree all contradictions that exist in the inventive problem can be performed. After that, the path to finding the physical characteristics of the X-element in the mathematical-physical model is facilitated, i.e. finding a real resource that will enable a HDIS of the inventive problem in an engineering system.

Published: July 2021

Introduction: Isoprenaline or isoproterenol (1-(3,4-dihydroxyphenyl)-2-isopropylaminoethanolhydrochloride; ISO), a synthetic b-adrenergic agonist, can be used to establish myocardial ischemia, cardiotoxicity, necrosis and/or an experimental model of infarction in rats. Aim: Determination of the dynamics of myocardial injury biomarkers production of aspartate transaminase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), and high-sensitive troponin T (hsTnT), with changes on electrocardiogram (ECG) parameters during the subcutaneous aplication of ISO in male Wistar rats. Material and methods: All animals (n = 23) were divided into two groups: control group (n = 11) treated with a saline solution, during two consecutive days (0,2 ml/kg b.m. daily, sc); and the ISO group (n = 12) treated with isoprenaline, during two consecutive days (85 mg/kg b.m. daily, sc). Blood was drawn from the rat tail vein in both groups, in order to determine serum activity levels of myocardial injury biomarkers, and an ECG (n = 6) was registered prior to the application, as well as 48h following the first dose of of saline solution or isoprenaline. Results: In comparison to the control group, in which no significant enzyme activities elevation (p > 0.05) nor ECG changes were registered, ISO group presented a significant rise of two clinically significant biomarkers of acute myocardial injury/myocardial infarction (AMI), CK (p = 0.05) and hsTnT (p < 0.01), as well as an ST segment elevation, with a patognomonic ECG change. Conclusion: Obtained results support previous studies, proving that isoprenaline represents an adequate experimental model for myocardial injury/AMI induction, and a "golden standard" for evaluating potential cardioprotective effects of pharmacological and non-pharmacological therapeutic modalities, with the ultimate goal of lowering the degree of lesions and improving post-infarction myocardium function.

Nostalgia de la Unidad Popular. Evolución de la forma cinematográfica en la obra de Patricio Guzmán
Authors: Martín Sanz Álvaro
Published: July 2021

Con una filmografía compuesta por más de una veintena de películas que se extienden a lo largo de más de cincuenta años, Patricio Guzmán es uno de los principales exponentes de la generación del Nuevo Cine Chileno que todavía sigue en activo. Su dedicación casi exclusiva al cine documental, plantea a través de una multitud de trabajos distintos acercamientos al Chile de Salvador Allende que amplían y ponen en cuestión los hechos recogidos en la historia oficial. La hipótesis de partida del presente artículo presenta la idea de cómo si bien toda la obra de Guzmán está basada en similares preceptos ideológicos, el paso del tiempo y el cambio de las circunstancias bajo las que nace su cine provocan una depuración de las formas y los estilos cinematográficos empleados en los films que realiza con posterioridad a la caída del gobierno de Unidad Popular. De esta forma, la obra del cineasta chileno sustituye la espontaneidad documental por una reflexividad mediada, la cual adquiere un componente poético bañado por la nostalgia de un pasado irrecuperable que abandona la innovación formal para buscar una contención en la imagen que además de transmitir el mensaje permite constituir un placer estético.
La literatura escrita por mujeres hoy: aproximación a su recepción y notas preliminares a un fenómeno incipiente. El caso de Colombia
Authors: Capote Díaz Virginia
Published: July 2021

En la década de los sesenta, Latinoamérica se situó con fuerza en el panorama literario mundial con la irrupción del boom, liderado fundamentalmente por cinco centros nacionales: Colombia, Perú, México, Argentina y Chile. Cincuenta años después, el mercado y la crítica ha-blan de un nuevo boom de la literatura latinoamericana, esta vez, protagonizado por mujeres nacidas, mayoritaria-mente, en Argentina, México, Perú y Chile. Sin embargo, en esta ocasión Colombia se descuelga del elenco y su papel es muy marginal. ¿Cuáles son las razones que excluyen, esta vez, a la literatura colombiana? A través de este mar-co de enunciación y mediante una aproximación a la re-cepción, atenderemos a la nueva producción de literatura escrita por jóvenes escritoras de América Latina, con el objetivo de trazar una panorámica general de lo que se viene denominando como un “Nuevo boom” de la narrativa femenina en el continente, llevando a cabo, sobre todo, una lectura de la legitimidad que las jóvenes escritoras de la región (nacidas entre 1970 y 1985) han obtenido tanto por el mercado como por la academia.

Health-saving technologies for citizens in the focus of urban planning policy
Authors: Astafyeva Olga Nikolaevna , Kuznetsova Irina
Published: July 2021

In the last few years, the approach “Urban Health” is gaining popularity in the world practice of municipal and state administration. Its peculiarity consists in the fact that in structuring any policies and making any decisions, priority is given to health and wellbeing of the population, and the key indicator of effectiveness is life expectancy. There is a range of works dedicated to ratio between physical and mental health of citizens and organization of the urban environment. However, the yet only Russian-language research on the practice of using Urban Health approach in different countries, the Russian experience is presented by Moscow alone and without emphasis on architecture and urban planning. The author systematizes the existing health-saving technologies that can serve as the foundation for environmental development programs; successful urban development programs of other countries are compared with such in Moscow and Russia, which allows revealing the merits and flaws of the latter. The conclusion is made that despite a set of measures presented in multiple programs and documents, which are aimed at improvement of health and well-being of the citizens, life expectancy and mitigation of risk of various diseases, do not appear as the goals of these programs. Therefore, urban planning policy can objectively be much more health-saving; the rhetoric and optics of the Urban Health approach, being articulated by the government,  can be more comprehensible for the population than the environmental agenda, and thus, promote the necessary urban changes.
Social fluidity mobilizes contagion in human and animal populations
Authors: Colman Ewan , Colizza Vittoria , Hanks Ephraim M , Hughes David P , Bansal Shweta
Published: July 2021

Humans and other group-living animals tend to distribute their social effort disproportionately. Individuals predominantly interact with a small number of close companions while maintaining weaker social bonds with less familiar group members. By incorporating this behavior into a mathematical model, we find that a single parameter, which we refer to as social fluidity, controls the rate of social mixing within the group. Large values of social fluidity correspond to gregarious behavior, whereas small values signify the existence of persistent bonds between individuals. We compare the social fluidity of 13 species by applying the model to empirical human and animal social interaction data. To investigate how social behavior influences the likelihood of an epidemic outbreak, we derive an analytical expression of the relationship between social fluidity and the basic reproductive number of an infectious disease. For species that form more stable social bonds, the model describes frequency-dependent transmission that is sensitive to changes in social fluidity. As social fluidity increases, animal-disease systems become increasingly density-dependent. Finally, we demonstrate that social fluidity is a stronger predictor of disease outcomes than both group size and connectivity, and it provides an integrated framework for both density-dependent and frequency-dependent transmission.

Published: July 2021

Background

Reliable assessment and understanding of student-athletes’ motivation for dual careers are crucial to support their career development and transitions. The purpose of this research was to examine the validity and usefulness of the student-athletes’ motivation toward sport and academics questionnaire (SAMSAQ-PT) in the Brazilian higher education context. Four studies were performed.

Methods

In study one, conceptually and semantic translation of the questionnaire and Bayesian exploratory factor analysis were conducted. In study two, a Bayesian confirmatory factor analysis with an independent sample was performed. In study three, Bayesian multilevel modeling was applied to examine the construct validity of the questionnaire in a cross-sectional sample. In study four, the SAMSAQ-PT sensitiveness was examined in a longitudinal sample, and the results were interpreted based on multilevel regression and poststratification.

Results

Altogether the results provided evidence validity and usefulness of the SAMSAQ-PT in Brazilian student-athletes. The Brazilian student-athletes’ motivation scores were sensitive to the influence of sex, sport level, and type of university on career and sport motivation. SAMSAQ-PT estimate scores across an academic year showed a trend of stability in the scores, adjusting for sex, sport level, type of university, and student-athlete status.

Conclusion

The SAMSAQ-PT proved to be a robust and valuable questionnaire, which could be used in Portuguese-speaking countries. The findings of the cross-sectional and longitudinal surveys urge to consider individual and contextual characteristics when investigating motivation of dual-career of athletes, also concerning the sex-related opportunities in university sports. Furthermore, there is a need for a call for action to promote and nurture the student-athletes motivation to remain engaged in both sports and educational commitments.

Bryophyllum pinnatum (Lam.) Oken (Crassulaceae) is used traditionally to treat many ailments. This study investigated the anti-inflammatory effect of hydro-ethanol leaf extract of Bryophyllum pinnatum on Wistar rats using acute and chronic models and also evaluates the bioactive compounds of the leaf extract. The phytochemical constituents of the plant extract were quantitatively determined by Gas Chromatography-Flame Ionization Detector (GC-FID) and acute anti-inflammatory activity was carried out with the aid of plethysmometer while chronic anti-inflammatory activity was investigated using cotton pellet. Results showed that the leaf extract of B. pinnatum was rich in kaempferol (7.006 ±0.02 μg/g), sapogenin (3.372 ±0.02 μg/g), rutin (1.837 ±0.01 μg/g) and lunamarine (1.359 ±0.01 μg/g). The findings showed that the plant had considerable anti-inflammatory effects in a dose dependent manner, returning edema in carragenean-induced and cotton pellet induced granuloma in Wistar rats to normal within 120 minutes and 7 days respectively. The findings of this work have shown that the leaf of B. pinnatum was rich in bioactive compounds which could be synthesized to produce new plant based product to fight inflammatory disorders with fewer side effects.

Aim: To determine the prevalence, pattern and risk factors of dating violence among undergraduate students of Usmanu Danfodiyo University Sokoto (UDUS).

Methodology: It was a descriptive cross-sectional study involving 340 undergraduate students, selected via multistage sampling technique. A structured self-administered questionnaire was used to collect data from the respondents, and data were analyzed using IBM SPSS version 26.0 and Microsoft Excel 2016.

Results: The ages of the respondents ranged from 18 to 29 years, with mean of 22.4±2 years; 218(66.9%) were males, 214(65.6%) were Hausa/Fulani and 266(81.9%) were Muslims. Majority of the respondents have been in a dating relationship for more than one academic year; 106(37.3%) of the dating partners were students of the university, of which 26(24.8%) were class mates. Current and lifetime prevalence of dating violence were 56% and 59.5% respectively. Form of dating violence experienced mostly by respondents was emotional/psychological violence [44(22.4%)], physical violence was the least experienced [27(14.04%)]. Up to 93(48%) of the dating violence took place on campus and 68(35%) of the perpetrators were current partners. Factors associated with dating violence included feeling overburdened by partners’ demands, and spending too much on partner.

Conclusion: Current and lifetime prevalence of dating violence were high and emotional violence was the commonest form of dating violence experienced by respondents. There is need for school authorities to put in place mechanisms to identify victims of dating violence and come up with measures aimed at stemming the tide of dating violence in university campuses.

A study on soil mineral fertilization was carried out over three years in three cocoa farms in the Nawa region of south-western Côte d'Ivoire. The aim of this study was to evaluate the effects of mineral fertilizers on the decomposition time of cocoa leaf litter. The experimental design was Fisher block with four treatments (T0, T1, T2, T3) repeated three times. The treatments were for T0, the control without fertilizer, for T1, NPK fertilizer 0-23-19, for T2, NPK fertilizer 0-15-15 + 17 CaO + 5 MgO + 1 B2O3 + 0.5 Zn and for T3, NPK fertilizer 4-10-10 + 19 CaO + 4 MgO + 0.8 B2O3 + 0.3 Zn. In each treatment, 3 plots of 1 m2 were delimited with a 1 cm2 mesh wire grid. The rate of decomposition of the cocoa leaf litter was made by measuring twice a year the weight loss of the ground litter contained in the plots. Comparison of the average decomposition rates between treatments showed that the fertilized soils had the best rates during the first 6 and 12 months of the trial. In Soubré, the T2 treatment (24.6±0.6%) in the 6th month and the T1 (72.6±6.6), T2 (82.4±1.6) and T3 (78.8±4.0%) treatments in the 12th month had the best decomposition rates. At Divo, treatment T1 (38.8±0.5%) in month 6 and treatments T1 (57.8±1.7%), T2 (67.9±10%) and T3 (66.9±7.7%) in month 12 were the best. At Méagui, decay rates did not differ between treatments throughout the trial. The application of mineral fertilizers resulting from soil diagnosis reduced the decomposition time of the cocoa leaf litter.
