Published: March 2024

Goal. To evaluate the resistance of tea-hybrid and floribunda roses to black spot caused by the fungus Diplocarpon rosae F.A. Wolf. (Marssonina rosae (Lib.) Died.).
Methods. Laboratory — for diagnosis of the disease and identification of its causative agent. Field — visual assessment of the distribution and degree of development of black spot (on a 6-point scale) on rose varieties under conditions of a natural infectious background. Mathematical and statistical — to assess the reliability of experimental results.
Results. The conducted studies show that during the growing seasons of 2022—2023, black spotting was widespread on all varieties of hybrid tea roses. The intensity of disease development ranged from 30 to 70%. The average lesion score was 1.5—3.5. Ascot, Fiesta and Charming Piano varieties were noted to have the lowest degree of damage (30%). Among roses of the floribunda group, the spread of the disease was in the range of 25—100%, and its development was from 5 to 70%. The average damage score of different varieties was in the range of 0.25—3.5. The least amount of black spotting was seen on plants of the Blu fo Y variety. At the same time, its intensity of damage was 5%. There were no immune groups among rose varieties of two garden groups. Of the 12 varieties of tea-hybrid roses, highly resistant ones were also not found. 3 varieties were resistant, 6 were moderately resistant, and 3 were susceptible. Of the 11 floribunda rose varieties examined, one variety was characterized by high resistance, 3 were resistant, 5 were moderately resistant, and 2 were susceptible.
Conclusions. According to the results of screening for resistance to black spot, 23 varieties of garden roses did not find immune roses among them. All studied varieties were affected by the causative agent of the disease D. rosae against a natural infectious background. Among the hybrid tea roses, Ascot, Fiesta and Charming Piano varieties are classified as resistant. The Blue Pho Yu variety (floribunda roses) was characterized by high resistance. Floribunda roses Sim Salabim, Bernstein and Four Elis were resistant to the disease. These varieties can be recommended for use in urban landscaping.

Published: March 2024

Goal. To provide data on insecticides for protection of grapes from thrips and Japanese grape cicada and their influence on the number of entomophages, which is an important element for the organization of effective and environmentally friendly technology of grape growing.
Methods. Combination of quantitative and qualitative methods in plant protection — entomology and biomethod. The use of generally accepted methods of analysis (hypothesis, experiment, induction and synthesis) provides sufficient information on the control of grape thrips and Japanese grape cicada under the conditions of using environmentally friendly means of protection, which is one of the main elements of modern technologies for optimizing agroecosystems and obtaining environmentally friendly products. The phytosanitary method of route surveys involves the identification of entomophages and the establishment of dominant species and prevalence of grape thrips and Japanese grape cicada among them. The field method ensures the study of the effectiveness of the elements of the integrated grape crop protection system. The laboratory method involved the identification of species diversity of beneficial fauna. The statistical method was used to calculate the data obtained, determine their accuracy and reliability.
Results. The database was updated with environmentally safe products, and regulations for their use were established, which are focused not so much on pest control as on the overall optimization of the phytosanitary condition of plantations, obtaining environmentally friendly products and preserving beneficial fauna. Under natural conditions, without pesticide pressure, the number of predators in a multicomponent entomocomplex is many times higher than in traditional agrocenoses.
Conclusions. The composition of preparations with a given direction of minimizing damage to beneficial fauna and, accordingly, the environment was formed. The results obtained and the conclusions formulated on their basis are of practical importance in terms of the prospects for the production of environmentally friendly products by applying environmentally friendly and effective methods of controlling the number of sucking pests and preserving the natural agrobiocenosis.

Authors: García-López Georgina-Isabel , Orozco-Vargas Arturo-Enrique , Aguilera Reyes Ulises
Published: March 2024

Se sabe que la maduración neuronal tras el nacimiento dura aproximadamente veinte años y necesita gran cantidad de energía. Si ocurre un embarazo antes de la maduración, la energía debe repartirse entre la madre y la cría, teniendo efecto en los procesos anatómicos y funcionales del cerebro. Por ello, se comparó la actividad eléctrica de la corteza frontal, así como el desempeño de sus funciones y cuidados maternales en adolescentes y jóvenes (con menos de seis meses posteriores al parto). Se aplicó el test NEUROPSI (atención y codificación) y un instrumento de cuidados maternales a primíparas adolescentes y jóvenes; a una muestra de esta población se les realizó registros electroencefalográficos. Se observan diferencias significativas en los procesos de codificación y atención (F= 4.5, α= 0.03*; F=79.7, α= 0.00**), y una correlación significativa entre la atención y el cuidado maternal (categorías de salud y cariño), así como de la codificación sobre el cuidado de la salud. La actividad eléctrica del lóbulo frontal fue más lenta en las adolescentes primíparas, así como las conductas de cuidado maternal. Lo anterior se relaciona con una menor maduración neuronal de madres adolescentes.

Authors: Kindo Shubham , Agrawal Narendra , Shori A.
Published: March 2024

The purpose of the investigation is to calculate soil infiltration rates with the help of infiltration models. The infiltration model helps to design and evaluate surface irrigation systems. The study calculated constant infiltration for two types of soils (clay loam soil and laterite soil) under field conditions (Unploughed and Ploughed). The double-ring infiltrometer has been implemented to experiment. The value of various constants of the models was calculated using the approach of averages counselled through a graphical technique. Fitting infiltration test data to prominent infiltration models such as Philip’s, Horton's and Kostiakov’s and The Nash- Sutcliffe efficiency (NSE), coefficient of determination (R2) and root mean square error (RMSE) statistics are used to evaluate the effectiveness of the model.  The results indicate that Philip's model is the most reliable, with R2, NSE, and RMSE values ranging from 0.9044-0.9677, 0.294-0.957 and 1.2647-5.7129, respectively. Therefore, under identical circumstances and without any kind of infiltration information, the above model can be employed to artificially produce infiltration information.

Published: March 2024

Yadgir district is identified as most backward ditrict by NITI ayoga on account of their “lowest composite indicators in terms of health and nutrition, education, agriculture, water resources, financial inclusion, skill development and basic infrastructure. Traditional community tanks (TCT’s) are classic examples of common pool resources that have been traditionally managed by local communities for irrigating their crops since age old and they are a living example that illustrates the capability of a man-made tank ecosystem evolved in harmony with nature to withstand natural disasters like drought, floods, and cyclones. These tanks not only protect and conserve the environment, but also contribute to livelihood security to rural farmers. These tanks have contributed significantly in agricultural production through supplementary irrigation and are declined recent decades in Yadgir district which is susceptible to drought compared to other district in the states. Such 13 TCT’s were rejuvenated for enhancing water storage capacity in the district under “Jal Samvardhane -District-wide Water Conservation Project” by Bharatiya Jain Sangh (BJS) In colloboration with Dept. of Agriculture, Yadgir. The study proved that, the average water storage capacity was raised by 24.80 percent in selected rejunuvented TCT’s. The average GWL increased for all selected tanks from 1.62 m to 3.81 m during the post-monsoon seasons of 2019 and 2020, respectively, compared to 1.31 metres before tank disiltation in Rabi 2018. Pigeonpea yield was increased by 4.13 percent (6.56 q/ha) to 20.57 percent (7.62 q/ha) with an average of 11.80 percent across all TCTs. Similarly, cotton prices increased by 4.85 percent (7.13 q/ha) to 21.53 percent (7.45 q/ha) throughout the growing season, with an average of 13.44 percent across all TCTs. Tank irrigation development activities have a substantial impact on groundwater recharge, access to groundwater, and in turn on the extension of irrigated water area. Tank irrigation development efforts have been shown to alter crop patterns, increase crop yields, and diversify crops, resulting in increased employment and farm income of small & marginal farmers of the Yadgir district.

Published: March 2024

In the present study twenty-eight hybrid combinations resulting from the half-diallel mating of eight quality protein maize (QPM) inbred lines were chosen in order to examine the potential to combine and gene activity for ten yield and component attributes. As part of the All India Coordinated Research Project (AICRP) on maize during the kharif-2020 season, the experiment was done at the research farm of college of Agriculture, Odisha University of Agriculture & Technology (OUAT) Bhubaneswar, using a randomized complete block design replicated thrice. Every observation recorded was subjected to statistical evaluation and it was revealed that the mean squares derived from the general combining ability (gca) and specific combining ability (sca) were highly significant (p ≥0.01). Estimates of sca effects   were greater than that of gca effects for all of the variables used in the study, suggesting to the predominance of dominant gene action. The inbred lines Q4-DQL 2221-1-1(833.792), Q2-DQL 2099 (517.658) and Q3- DQL 2159 (350.325) shows high gca effects for yield and its attributing traits due to more additive gene action thus identified as good general combiners for yield. Twelve of the twenty-eight crosses showed significant (p ≥0.01 and 0.05) positive sca effect on grain yield. The best experimental crosses for grain yield based on per se performance and sca effects were Q2 x Q8 (2106.748), Q1 x Q6 (2053.048), Q3 x Q7 (2027.082), and Q3 x Q6 (1719.884).
Sustainable utilization of biogas technology: A promising solution to combat the energy crisis in India
Authors: Raipurkar Kavita S.
Published: March 2024

India is facing a significant energy crisis due to its rapidly growing population, which is not being met by an equivalent increase in energy supply. According to the US Energy Information Administration, India's electricity consumption is projected to grow by 3.3% annually until 2035. Biogas technology, which converts waste into clean energy, offers a promising solution to this problem and accounts for 9% of global energy consumption. Despite being introduced in 1981, biogas technology's potential in India remains largely untapped, with only 7.34 MWe of off-grid projects generated by 2020. However, Tamil Nadu and Karnataka have significant potential for biogas generation. The National Biogas and Manure Management Program (NBMMP) have installed 5,056,139 biogas plants between 1981-82 and 2020-21, with Maharashtra being the top performer. India's agrarian economy provides ample raw materials for biogas generation, making it a crucial renewable resource for the country's energy crisis. Given the pressing need to address global warming, greenhouse effects, depleting fossil fuels, and pollution, biogas technology is essential for a cleaner, more sustainable future. Focusing on biogas technology can help India meet its increasing energy demands and contribute to a cleaner and more sustainable future. From 2018-19 to 2020-21, the NBMMP received a total allocation of INR 1,439,249,000.

Published: March 2024

This paper elaborates the geo-politics, the American security Alliance and the North East Asian regional stability during the Cold War period (especially in the early decades after the outbreak of the Cold War in Asia). The American security alliance in the North East Asian region is different with the American security alliance in the other region. The American formed bilateral security alliance with the pro-American powers in the North East Asian region; The U.S.-Japan Alliance 1951, The U.S.-South Korea Bilateral Agreement 1953 and the U.S.-Republic of China (Taiwan) in 1954. These bilateral agreements that were signed in the early years of the Cold War still effective and play their role in the today regional power configuration. The objectives of the study are: to explore why the American security Alliance with his alliance state in the North East Asia is totally different with the American security alliance in the other region. In the other region the American created multi-lateral alliance, such as NATO (North Atlantic Treaty Organization) in North Atlantic/Europe and SEATO (south East Asia Treaty Organization) in South East Asian region. There is no NEATO (North East Asia Treaty Organization) in the North East Asian region. This study concludes the factor of geo-politics, domestic and leadership factors in the American alliance state in the North East Asia and the structure of communist powers in the North East Asia influenced the American to create the bilateral security alliance rather than a multi-lateral. The Bilateral security structure give the American more power in controlling security decision and creating better degree of North East Asian regional stability.

The prevalence of social, economic and environmental issues and problems around the world seems to surpass what the traditional entrepreneurship education could handle. Hence, the emergence of social entrepreneurship education as a complement to the traditional entrepreneurship education and empowerment for achieving the sustainable development goals (SDGs 2030). Therefore, this study was carried out to determine the social entrepreneurship awareness and orientation of Business Education students in tertiary institutions to ensure their empowerment for realizing the Sustainable Development of the Nigerian economy. The study raised and answered two related research questions and also formulated and tested three relevant research hypotheses. The descriptive survey research design was adopted for the study. The population of the study comprised all final-year Business Education students in public universities and public colleges of education in Lagos State, Nigeria. The sample size for this study consisted of one hundred and five (105) final-year Business Education students randomly selected from the sampled population. The research instrument used was structured questionnaire. The Cronbach Alpha correlation coefficient used to determine the internal consistency of the research instrument yielded an average index of 0.85. The research questions and hypotheses data were analysed using mean and t-test statistical tools respectively. Findings show that Business Education students had little awareness and orientation about social entrepreneurship education, and were ill-empowered for Sustainable Development Goals 2030. It was recommended that social entrepreneurship education content and instructional strategies should be included in the curricula, with collaboration among the students, the institutions and the communities.

The main purpose of this study is to examine the existence of cycle relationship between ESG disclosure and financial performance of listed companies in Malaysia, Singapore and Thailand. The secondary data of total 140 companies was extracted from Bloomberg database for period 2011 to 2016. The ESG disclosure of corporate is represented by ESG disclosure score, while earnings per share (EPS) is used to measure the corporate financial performance (CFP). Two years lag effect was assumed in this study to test how CFP in period 1 (2011-2012) influences ESG disclosure score in period 2 (2012-2014), and how period 2 ESG disclosure score affects the subsequent CFP, which is defined as CFP in period 3 (2015-2016). The empirical results of this study found significant positive (negative) cyclic relationship for Malaysian (Singaporean) companies, while no significant cyclic relationship is found for companies in Thailand. The findings suggest that only Malaysian companies gain the financial appreciation from making sustainability reporting through reducing information asymmetry to stakeholders.

The study aimed to determine the effectiveness of the Linear Motion Graph learning module (PGeL) among Form Four students. The design of this study is the developmental research which involves the development of the PGeL learning module based on the ASSURE instructional design model. The module was developed by applying chunking elements, mnemonic, interactive simulations, POE approach (predict, observe and explain) and graphics techniques. The effectiveness of the PGeL module was investigated using the quasi-experimental design. A total of 94 secondary school students in Kuala Lumpur zone were selected as respondents using the cluster random sampling technique and consist of two groups; the treatment group and the control group. The effectiveness of the PGeL learning module was determined using pre-test and post-test question sets. Data analysis was carried out using the Statistical Package for the Social Science (SPSS) software. The findings showed that the developed PGeL learning module had high face validity and content validity of 97.1% and 95.3%, respectively. The pre-test and post-test questions were used to collect information on student achievement in the Linear Motion Graph topic. Analysis of student responses in context found that the treatment group showed a better improvement in achievement compared to the control group, with the best improvement being in problem-solving contexts. Independent samples t-test analysis showed that there was no significant difference in the pre-test score between the treatment group and the control group [t (92, p = 0.824) = -0.223, p>0.05]. Independent samples t-test analysis also showed that there was a significant difference in the post-test score between the treatment group and the control group [t (92, p = 0.000) = 10.919, p<0.05]. Furthermore, independent samples t-test analysis showed that there was a significant difference in achievement between the treatment group and the control group [t (92, p = 0.000) = 12.622, p<0.05]. In conclusion, the developed PGeL learning module is effective in improving the achievement of form four students in the Linear Motion Graph topic. The implication of this study is that the PGeL learning module is suitable for use as a learning aid for the Linear Motion Graph topic.
