Authors: Bansal Harshit , Pawar Neeraj , Kumar Keshav , Kumar Rohtash , Singh Ajay , Bhupender
Published: September 2024

Land degradation, particularly through waterlogging and soil salinization, poses a significant threat to agricultural productivity, especially in arid and semi-arid regions. This study examined the economic impact of these issues on crop returns in Haryana, India, with a focus on Jhajjar district. The research assessed input utilization, crop yields, and profitability for Bajra and Mustard crops on both normal and degraded farms. Utilizing primary data from 60 farmers and employing tabular analysis and the Cobb-Douglas production function, the study found that soil salinity and waterlogging lead to significant reductions in crop productivity and profitability. For instance, Bajra yields on degraded farms resulted in lower gross returns and net profits compared to normal farms, primarily due to increased costs in field preparation and pest management. The Cobb-Douglas production function analysis further revealed that while fertilizers significantly enhance yields on normal farms, their effect is negative on degraded farms, likely due to over use of fertilizers. Mustard farming showed similar trends, with problematic farms incurring higher variable costs and achieving lower profitability. The study highlighted the urgent need for targeted policies to manage soil health and improve the economic outcomes of farming in degraded lands.
Analysis of the Relationship between Public Debt Service and Education Expenditure: A Pooled Mean Group Approach
Authors: Mbewe Gift
Published: September 2024

This study examined the relationship between public debt service and education expenditure in 15 Sub-Saharan and South American countries from 1995 to 2022. Utilizing the Pooled Mean Group (PMG) estimation method within an Auto Regressive Distributed Lag (ARDL) framework, evidence of cointegration between public debt service and education expenditure is presented. PMG regression results indicate that, in the short run, public debt service does not have a statistically significant impact on education expenditure per student. However, in the long run, an increase in government debt service exerts a significant negative effect on education expenditure. This result aligns with existing literature, which argues that increased debt obligations divert financial resources away from essential public services, including education. The Hausman test confirmed that the PMG estimator was more efficient than the Mean Group (MG) and Dynamic Fixed Effect (DFE) estimators. These findings suggest that maintaining low debt levels is crucial to prevent adverse impacts on educational funding, which is vital for long-term economic development.

Published: September 2024

The nutritional quality of meals served in prisons is crucial for inmate health. However, it is often overlooked in developing countries like Côte d'Ivoire. This study assessed the nutritional value of meals served at the Abidjan Penitentiary Center (PPA). Standard biochemical analyses determined the macro- and micronutrient content of cooked meals served to male inmates in January and July. The average weekly nutritional intake of each nutrient was then calculated. The results reveal that two meals are served daily at PPA, following with national guidelines. These meals were often monotonous, especially in July. Breakfasts were low in calories, while most lunches were hypercaloric. However, the meals were insufficient in both quantity and quality. Most (73%) daily intakes of macro- and micronutrients did not meet half of the nutritional recommendations. Significant deficits in calories, lipids, potassium, and vitamin B1 were also observed, exposing inmates to risks of nutritional deficiencies and associated diseases. In conclusion, the diet at PPA is inadequate, necessitating a revision of food policies to ensure optimal nutrition. Diversifying menus and increasing portion sizes should be priority actions to improve inmate health.

Published: September 2024

The present research conducted in Adilabad and Mahabubnagar districts of Telangana state was purposively selected for the study. An ex-post facto research design was adopted in the present investigation. The study was conducted in twelve villages selected from two manuals of each district, which included 20 farmers from each of the selected villages, a sample of 240 farmers was selected for the study by simple random sampling method. This study examines the responses and coping strategies of affected communities in these districts to climate variability. The analysis of the perception of the cotton growers indicates that the majority of the respondents had a medium (58.33%) level of perception followed by low (24.17% and high (17.50%) levels of perception. Age, farming experience, land-holding family size, achievement, credit and subsidy orientation and risk orientation were positively and significantly related to the perception of the cotton growers in combating climate variability. Annual income, extension contact, social participation, and Cosmo politeness preparedness to adaptation showed a non-significant relationship with the perception of cotton growers towards climate variability.
Effect of Ash, Crude Protein and Nitrogen in Traditional Varieties of Rice Against Sitophilus oryzae (L.) Infestation in Storage
Authors: Kishore Telugu , Sathish R. , Reddy S. Srinivas , Kumari J. Aruna
Published: September 2024

The management of rice weevil infestations in traditional rice varieties presents unique challenges. Traditional storage practices and methods may not always align with contemporary insect pest management strategies furthermore, the genetic diversity of traditional rice varieties means that insect pest management solutions need to be tailored to specific varieties and local conditions. Twelve rice varieties were collected from different Farmers of Telangana State. The selected varieties, after collection, were cleaned by removing physical impurities if any and thereafter they were kept in an incubator at a temperature of 55⁰C for four hours to kill the existing insects without damaging the viability of the seeds. In this study, the reduced adult emergence in moderately resistant varieties could be linked to their elevated ash content. This high ash content in the seeds may deter insects due to potential toxicity, rendering these varieties less preferred for feeding, growth, and emergence by the grub, and high crude protein and nitrogen content enhances nutritional content and attractiveness, promoting growth and reproduction and increases egg laying resulting in more extensive damage to the stored rice. The present results of ash, crude protein and nitrogen content can guide the selection and breeding of traditional rice varieties with lower weevil susceptibility and perform storage practices that minimize rice weevil infestations and also improves traditional storage practices by identifying natural pest resistance and proper hermetic storage practices.
East Africa’s Renewable Energy Diversity Landscape: A case of Kenya’s Potential, Progress and Future Prospects
Authors: Kimutai Stephen K. , Kimutai Isaiah K. , Kiplagat Mohamed K.
Published: September 2024

East Africa holds enormous renewable energy (RE) resources, including solar, wind, geothermal, hydroelectric power and green hydrogen, yet there remains a substantial gap in harnessing these resources to meet rising energy demands and mitigate climate change. This study focuses on Kenya, aiming to assess its renewable energy potential, examine current infrastructure, and chart future paths for sustainable development. Geothermal energy makes up 28.8% of Kenya's total installed capacity (3,264.42 MW), with hydro, wind, solar, and bio-energy contributing 25.5%, 13.3%, 7.4%, and 0.1%, respectively, accounting for about 75% of the total generation. Despite this, utilization rates are low: hydro at 10.7%, geothermal at 9.4%, wind at 7.3%, solar at 1.6%, and bio-energy at 1.5%, revealing substantial underutilization. Kenya currently generates 2453.9 MW of RE, with ongoing projects poised to raise this capacity to 3982.9 MW, inclusive of those under development. Compared to other East African countries, Kenya leads, with Uganda at 1,245.5 MW, Tanzania at 848 MW, Burundi at 46.7 MW, Rwanda at 166.7 MW, and South Sudan at 74 MW. By 2032, Kenya aims to add 350–450 MW of Green Hydrogen power and 150–250 MW of electrolyzer capacity to replace 50% (300,000–400,000 tonnes annually) of nitrogen fertilizer imports. The study underscores the need for greater investment in infrastructure, research, and capacity building to unlock East Africa’s renewable energy potential, highlighting that strategic partnerships and investor collaboration are crucial for closing the capacity-to-use gap and achieving a sustainable energy future for the region and globally.
Development of the Control System of the Level with Controller
Authors: F.H. Agayev
Published: September 2024

The purpose of the study is to control the level of water in reservoirs. For this, the importance of ensuring the optimal operation of pumps, electric drawers, control panels, and communication devices is justified. Innovations obtained as a result of research:
The proposed Control system has the ability to work in 3 modes: direct local control (classical model), manual control by means of a computer (control is performed from a center, but the operator controls the entire process) and automatic control.
Organization of the optimal operation of the devices: by ensuring the alternating operation of artesian pumps and pumps pumping water from the intermediate reservoir to the main reservoir, the longevity of the devices was ensured
Comfortable management: If the operators had to monitor the system by covering an average distance of 3-4 km during the day, now they have achieved more comfortable and at the same time more reliable management with a single central control.
Savings: if before the system was installed, water was discharged to the evacuation line with a certain intensity, now water losses have been prevented by means of more flexible management.

Published: September 2024

The selective ovipositional behaviour of Fall armyworm (FAW), Spodoptera frugiperda was studied at Centre for Agro Climatic Studies under field and laboratory conditions through cage experiments to provide the basis for its oviposition preference on different crops to find an ecological solution for its management. Oviposition preference of S. frugiperda was evaluated under free choice and no choice conditions with maize, sorghum, groundnut, cotton, cabbage, chickpea and tomato. The results of the experiment revealed that the number of eggs laid by the FAW on maize (208.7 ± 7.00) was high when compared to sorghum (110.3 ± 10.0) under filed conditions. But, in case of laboratory conditions under no choice test females preferred to oviposit on maize, sorghum, groundnut, cotton and cabbage except on chickpea and tomato. Egg masses per plant was maximum on maize in both field and laboratory conditions followed by sorghum. Information of hierarchies of S. frugiperda host plant oviposition preference by females will be useful in developing strategies for the management of this pest.

Authors: Chavda Rucha , Kothari Krupali , Assudani Hitesh , Rathwa Jimisha , Solanki Vaishali
Published: September 2024

Background and Aim: Antibiotic resistance is often seen as a potential consequence of using antimicrobial agents. This issue has been observed in cases of long-term prophylaxis for UTI and in elderly patients with renal failure. The purpose of this study was to determine the prevalence of UTI and evaluate the antibiotic sensitivity patterns.
Materials and Methods: This study presents a clinic-pathological analysis conducted for urine analysis in the department of urology and other associated departments of the Gujarat Adani Institute of Medical Sciences, Bhuj, Gujarat. A total of 181 urine samples were collected from patients with UTI at GK General Hospital, from various departments, ensuring a sterile environment. The identification and Antibiotic susceptibility testing (ABST) were conducted following standard microbiological guidelines. The results were interpreted according to the guidelines set by CLSI M100 (Clinical and Laboratory Standards Institute).
Results: We processed a total of 181 urine samples from various departments of the medical college. The study included 120 females and 61 males, with a ratio of 2:1. Positive growth was observed in 96 samples, which accounts for 50% of the cases. E. coli was the most frequently identified isolate, appearing in a total of 32 samples. It was followed by Klebsiella pneumoniae and Pseudomonas aeruginosa. Based on the antibiotic sensitivity testing, Nitrofurantoin demonstrated a sensitivity rate of 84.37% in E. coli isolates. However, Fluoroquinolones such as Ofloxacin, Levofloxacin, and Ciprofloxacin exhibited lower sensitivity rates of 37.5%, 31.25%, and 31.25% respectively.
Conclusion: E.coli is the most common pathogen that causes UTIs. After comparing two groups of antibiotics, it was found that Nitrofurantoin is the most sensitive oral antibiotic when compared to fluoroquinolones. Because of its exceptional sensitivity, it can be used as an empirical treatment for UTI at our centre.
