Authors: Kurniatillah Nia , Hayat Fauzul , Masyruroh Anis
Published: June 2023

Background: Open defecation remains a public health problem in Indonesia, contributing to various diseases such as diarrheal diseases within communities. Open defecation can be influenced by several factors, including socio-demographic, cultural, financial, and poor sanitation factors. However, these factors remain poorly investigated.

Objective: This study aimed to determine the association between age, gender, level of education, knowledge, attitude, family income, local government support, availability of clean water, and family latrines with open defecation behavior in Serang City, Banten Province, Indonesia.

Methods: A cross-sectional study design was selected, using purposive sampling in the study area. Data were collected from 220 respondents using a structured questionnaire from June to October 2022. Chi-square test was used to analyze the data.

Results: The majority of the respondents were females (52.7%), and the dominant age group was >30 years old (50.9%). Bivariate analysis showed a significant relationship between gender (OR = 8.190, 95% CI =4 .460-15.038), attitude level (OR = 2.391, 95% CI = 1.271-4.500), family income (OR = 35.964, 95% CI = 8.477-152.582), local government support (OR = 4.540, 95% CI = 2.073-9.943), availability of clean water (OR = 2.834, 95% CI =1.632-4.922), and family latrines (OR = 19.260, 95% CI = 9.612-38.591) with open defecation behavior (p <0.05). There was no significant relationship between age, level of education, and knowledge with open defecation behavior (p >0.05).

Conclusion: The main variables that significantly influenced open defecation behavior were female gender, family income, local government support, and family latrines. Therefore, there is a need for a policy shift to involve female empowerment and local government support to construct affordable and effective latrines, aiming to improve the current practice and eliminate open defecation.

Published: June 2023

Background: Indonesia recently implemented a National Health Insurance program while simultaneously grappling with the challenge of unmet family planning needs.
Objective: This study aimed to examine the correlation between health insurance ownership and the utilization of family planning methods among married/in-union women in Indonesia.
Methods: This study employed secondary data analysis using the 2017 Indonesian Demography and Health Survey (IDHS). The analysis included a sample of 18,411 married/in-union women. Univariate, bivariate (Chi-square test), and multivariate (binary logistic regression) analyses were conducted to examine the relationship between health insurance ownership and the utilization of family planning methods.
Results: The analysis revealed that a small proportion of individuals with health insurance utilized family planning services. Several factors were found to be associated with the utilization of family planning services, including ownership of health insurance, women's age, family planning decision-maker, socioeconomic status (as measured by being in the richest quintile), and higher education attainment.
Conclusion: The findings of this study provide important insights for policymakers and public health practitioners regarding the integration of national health insurance programs and family planning initiatives in Indonesia. It is crucial to address the low utilization rate of family planning services among those with health insurance. Future research should focus on fostering collaboration among all stakeholders to promote comprehensive education on freely accessible contraceptive methods, aiming to bridge the gap between policy implementation and effective utilization of family planning services.

Published: June 2023

After the adoption of the UN Convention on the Rights of Persons with Disabilities, the issue of inclusivity occupies an important place on the agenda of educational reforms. The purpose of this policy is to find ways to increase the participation and education of students who belong to socially vulnerable groups and are at risk of exclusion from school and beyond. The scientific relevance of the problem lies in the fact that despite the importance of leadership in inclusive education, there are critically few works devoted to this topic, especially in Russia. The purpose of the study is to review and theoretically analyze scientific publications on the topic of leadership in inclusive education. In the article, the main types of leadership are considered; special attention is paid to the dominant theories of transformational and transactional leadership, leadership research tools in inclusive education. The leadership style significantly influences the views, behavior, communication of teachers, their self-efficacy, and learning strategies. When preparing future leaders of education in master's degree programs, it is necessary to form ideas about the types and importance of management style in school, to form skills of effective communication, motivation, intellectual stimulation. The prospects of the study are to conduct research on the influence of the leadership style of Russia school principals and the attitude of teachers to inclusive education, their teaching strategies.

Published: June 2023

The results of a student`s anonymous questionnaire of the Khanty-Mansiysk State Medical Academy relying on the satisfaction level of the teaching anatomy at the department of human anatomy, operative surgery and gross anatomy were conducted for annual selfexamination from 2014 to 2022 as part of the quality management system. It was revealed that the periods of transition to the new state educational standards, as well as the level of the adjustment of students to the requirements of the first year semester, negatively affect the satisfaction with the quality of the educational process. Lectures conducted via computer-based learning resources did not affect the quality of the educational process and the satisfaction of respondents, and was preferred option instead of attending lectures. The remote form of practical training is not acceptable for studying the anatomy at the medical university, because it keeps students away from educational base and extracurricular work, not allowing them interact with the objects of study and the teacher. Thus, the annual monitoring of satisfaction level of the educational process helps to improve the work of the faculty, the material, technical and educational equipment, modernize teaching methods and thereby increase the interest of students in mastering in the anatomy.

Authors: Milovanova Natalia G. , Kadyrova Suliya S.
Published: June 2023

In modern conditions of the development of the information society, there is a tendency to complicate the content and structure of the identity of the individual, which is the result of his free choice. Simple identification with cultural patterns becomes impossible due to the blurring of value orientations, unified, standardized norms and values imposed by mass culture, the media and communications, virtual reality technologies. Children, adolescents and young people have problems identifying themselves as a person in society due to the multiplicity of self-images that can coexist and conflict at the same time. Actualization of the problem of ethnic identity is especially acute for the pedagogical community: along with the need to educate a citizen and a patriot in the implementation of state policy in the field of education, this problem is no less relevant for vocational education that trains teachers. Appeal to the problem of the formation of ethnic identity is connected, first, with the socio-cultural changes taking place in society, the processes of modernization of education. The ethnic identity of a developing personality is determined by a complex interaction of various factors (historical, geographical, religious, and sociocultural). The declared priorities of the state policy in the field of culture and education, national policy, first, aim at the formation of civic identity in a multicultural and multi-confessional society, a component of which is ethnic identity. The purpose of the article is to refine the concept of ethnic identity in the context of the study, to describe the technology of forming the ethnic identity of students by means of extracurricular activities, and to present the results of an empirical study. The article discusses the possibilities of extracurricular activities for the formation of ethnic identity, taking into account the regional context at the level of primary general education. An interpretation of the results of the empirical study and conclusions are presented.

In order to find out the performance of castor under decontaminant treated heavy metal polluted soils, an experiment was conducted at Students Farm, College of Agriculture, PJTSAU, Rajendranagar, Hyderabad, during kharif 2016 to study the performance of castor in heavy metal polluted soil under the treatments of various decontaminants (various dosages of phosphorus as well as, quick lime). The dry matter before flowering, and stalk yield at harvest of castor varied from 429 to 516, 1460 to 1758 kg/ha, respectively. Among the different decontaminants highest dry matter yield and stalk yield (516 and 1758 kg/ha at before flowering and harvest) and seed yield (1720 kg/ha) was obtained in T5 (RDF+CaO @ 2 t/ha), which was significantly superior over all other treatments and on par with T4 (RDF+CaO @ 1 t/ha), and per cent increase over RDF was 20.41 and 23.56, respectively for stalk, and seed yield of castor. Decontamination treatments had reduced the mean Pb, Cd, Ni and Co contents of castor to 4.51, 0.65, 0.95 and 0.63 mg/kg, and increased mean uptake to 7.62, 1.17, 1.69 and1.09 g/ha respectively, for Pb, Cd, Ni and Co in seed at harvest. The  Pb, Cd, Ni and Co contents of soil after harvest of the castor crop ranged from 17.11, 0.79, 1.89 and 1.22 mg/kg in the reference control and decreased to 14.60, 0.68, 1.67 and1.02 with RDF+CaO @ 2 t/ha treatment. The reduction in Pb, Cd, Ni and Co concentration in post-harvest soil was more due to Cao at different levels when compared to high phosphorus.

Authors: Dutta Rupam Kumar , Bhattacharjee Deepa
Published: June 2023

In the Leh valley, apart from the river Indus, several nalas have a great significance on development of a number of villages and settlement areas. The present work is an effort to illustrate the pivotal role of the Stakmo nala in establishment of the Stakmo village. The study also seeks to emphasis the necessity of the nala basin management to sustain the natural resources for the existence of the villages. Various problems related with Leh city and its adjacent area have been studied by several scientists. However, most of the scientists hardly show interest in depicting the comprehensive roles of the different nalas for the construction of many settlement areas and their related issues in the Leh valley. Present authors have tried to unfold the role of nalas in development of landforms and land use pattern with special reference to Stakmo village, Leh valley. Along the Leh valley there are11 important nalas which have key role to supply necessary natural resources to develop a number of important villages and settlement areas. Undoubtedly, availability of natural resources of an area greatly influenced by the process of landform development and their characteristics, because landscape characteristics play a significant role in generation of local natural resources. Hence, in order to illustrate the significant role of the Stakmo nala in development of landforms and land use pattern in Stakmo village and its adjacent area, the authors analysed vivid geomorphic features of the Stakmo nala basin based on quantitative approach including morphometric techniques and field observation. Apart from morphometric analysis, field based data regarding nala sediment size, rock types, micro features, varied land use pattern of the Stakmo village including perception study of the local people have been tried to discuss in the work.

Published: June 2023

Briquettes offer good value in terms of energy density. Briquetting of sawdust with paddy straw is a ray of hope for paddy straw waste utilization, which has been a burning issue in India for a long time. A commercial briquetting machine was used to make briquettes of sawdust with paddy straw in two different forms—shredded and chopped, in different ratios, separately. The ratio of paddy straw in briquettes was increased until the produced briquettes had an acceptable firmness. The maximum ratio of shredded paddy straw for which briquetting was possible was 40:60 with sawdust, whereas for chopped paddy straw it was 60:40 with sawdust. The briquettes were then analysed for different properties to assess their quality and durability. The shatter index of shredded straw briquettes and chopped straw briquettes varied from 0.10–10.12% and 0.26–4.54%, respectively. The friability index of shredded straw briquettes was in the range of 93.54-99.85%, whereas for chopped straw briquettes it was in the range of 89.89-99.90%. The volatile matter of shredded straw briquettes ranged from 79.60-83.89%, whereas for chopped straw briquettes it ranged from 76.69-86.07 %. The ash content of shredded straw briquettes was in the range of 9.83-13.07%, whereas for chopped straw briquettes, it was in the range of 6.60-16.44%. The fixed carbon content of shredded straw briquettes varied from 0.09 to 0.87%, whereas for chopped straw briquettes it varied from 0.11 to 0.59%. The results suggested that the densification experiments were successful and the briquettes produced were of good quality

Published: June 2023

The present investigation on correlation and path analysis studies helps to study the relationship among the yield and yield contributing traits along with the quality parameters. The observations were taken in the F1 population of 35 hybrids along with lines (7 lines) and testers (5 testers) for the traits viz. plant height (cm), number of sympodial branches per plant, the number of bolls per plant, boll weight (g), lint index (g), single cotton yield per plant (g), ginning outturn (%), upper half mean length (cm), elongation percent (%) and micronaire value (µg per inch). The results revealed that seed cotton yield per plant had strong and positive association with the traits namely number of sympodial branches per plant (0.646), number of bolls (0.633) and boll weight (0.652). Path analysis study revealed that number of sympodial branches per plant (1.5396), boll weight (0.6285), lint index (1.3526) and upper half mean length (0.3392) had high direct positive effects on single plant yield and indirect very high positive effects through the traits viz., number of sympodial branches per plant via., number of bolls per plant (1.5125) and boll weight (1.0121). Hence selection based on these traits that are positively associated and direct positive effect with the yield would produce the best outcome in the genotypes in further breeding programmes.

Published: June 2023

Land use/land cover (LULC) changes influence the ecological function, consequence on ecosystem services, which are tightly linked to human wellbeing. However, quantification of the LULC changes and identifying the underlying factors remain patchy particularly in developing nations, despite this information is crucial to propose a feasible restoration action. Therefore, this study investigates the land use/land cover changes and its drivers in central Rift Valley, Ethiopia. GIS and Remote sensors i.e. Landsat 5 (TM), and Landsat 8 (OLI/TIRs) imagery sensors acquired from USGS, and field observation were used. Using the supervised classification method and the support of ArcGIS 10.5 and ERDAS IMAGINE 2014, all images were classified into various land cover types. Focus group discussions, key informant interviews, and structured questionnaire surveys were used to investigate the drivers of LULC change. NDVI was used to detect the vegetation cover change. Woodland, grassland, and barren lands were the major LULC types identified in this study. After 28 years, the woodland cover increased from 20.6% to 40.2% whereas the barren land decreased from 43.4% to 22.6%. Grassland showed very slight increment, i.e. from 35.9% to 36.9%. This implies that area enclosure plays a significant role in the restoration of degraded lands. The highest NDVI values (0.6) were determined in the year 2022 at the end of the classification. Focus group discussants and key informants confirmed that human-induced factors were the major drivers of LULC changes in the study area. Our findings indicated that human interventions are the key determinants of land use/land cover dynamics, and as a result, enforcement of the law and public education campaigns to change human behavior in support of the area enclosure approach are essential to restoring degraded land for the benefit and wellbeing of humans and nature while also advancing the achievement of the global goals.

Almost, in all flora and fauna, the species richness is affected by environmental changes; hence it is important to survey regularly to understand the current composition and diversity of different wildlife species in an ecosystem. The present study surveyed to assess the species distribution, conservation status, abundance and diversity of birds using the point count method, at two different habitats, a wetland (BhikundJheel; BJ) and a forest (Arjun Van; AV) in Hastinapur wildlife sanctuary, India. We surveyed early in the morning (before and after sunrise) and evening (before sunset) for 20 min at every point from January 2019 to April 2019. A total of 96 bird species were recorded, which belong to the 40 families and 15 orders. Out of 96 species, we recorded 67 resident bird species and 29 migratory bird species. The number of bird species specific to the type of habitat was higher in BhikundJheel than those in Arjun Van. The species richness and abundance were higher in the wetland (81; 5605)than in the forest habitat(45; 1716); however, evenness (J’) and diversity [Shannon-Weiner (H’) and Simpson diversity (D)]indices were higher in the forest habitat (J’: 0.827, H’: 3.420, D: 0.960) than in the wetland habitat (J’: 0.669, H’: 2.940, D: 0.827). Overall, we found that in the wetland habitats had more species richness than in the forests.
Management of agriculture through artificial intelligence in adverse climatic conditions
Authors: Gupta Sheetanshu , Singh Nirbhan , Kashyap Shakuli
Published: June 2023

Climate change has been a significant global challenge in recent years, resulting in adverse conditions for agricultural crops. Adverse climatic conditions, such as drought, flood, and extreme temperatures, have a significant impact on crop yields, resulting in food insecurity, economic losses, and environmental degradation. Agricultural experts have been working to develop innovative technologies to help farmers manage their crops better in adverse climatic conditions. One such technology is the use of Artificial Intelligence (AI) to model and manage agricultural crops. The main concern of this paper is to find the various applications of Artificial intelligence in agriculture to optimize irrigation and fertilizer application in adverse climatic conditions. By analyzing data on soil moisture levels and weather patterns, AI algorithms can determine the optimal timing and amount of irrigation and fertilizer application to maximize crop yield while minimizing water usage and fertilizer runoff. AI-based modeling and management of agricultural crops in adverse climatic conditions can help farmers improve crop yields, reduce costs, and mitigate the effects of climate change.

Neftqazçıxarmada rast gəlinən sistemlər bir qayda olaraq dispers mühit olmaqla ən azı iki fazadan ibarət olur və bu zaman bir faza parçalanaraq digər fazada paylanmış olur. Ümumiyyətlə, neftin və qazın çıxarılması, yığılması və nəqli multifazalı texnologiyalara əsaslanıb və quyu məhsulunun laydan çıxarılması, separasiya qurğularına doğru hərəkəti, fazalara ayrılması və mədənarası hərəkəti çoxfazalı olmaqla neft, qaz, lay suyu və mexaniki qarışıqlardan ibarətdir.
Neftqazçıxarmada və karbohidrogenlərin nəqli zamanı texnoloji proseslərin böyük əksəriyyəti dispers sistemlərin parçalanmasını tələb edir. Praktiki olaraq hesab olunur ki, emulsiyaların parçalanması üçün tətbiq olunan hidrosiklon texnologiyaları yararlı deyil, baxmayaraq ki, suspenziyaların parçalanması, mayelərin bərk hissəciklərdən təmizlənməsi, məsələn gil məhlulunun şlamlardan təmizlənməsi zamanı bu qurğular istifadə olunur.
Son illərin tədqiqatları əsasında müəyyən edilmişdir ki, multifazalı silindirik axınların əsasında dispersion və dispers fazaların qarşılıqlı təsiri durur ki, bu təsirin hərəkətverici qüvvəsi axının en kəsiyində yaranan və mərkəzinə doğru yönələn quvvə hesab olunur.

Hydraulic fluid is an indispensable element of any hydraulic system, in addition to its main function - the transfer of mechanical energy in the hydraulic system - it prevents accelerated wear of equipment parts and, thanks to special additives, from corrosion, contributes to the normal operation of the hydraulic system under various conditions: it provides heat exchange between the components of the hydraulic system with environment, and also acts as a lubricant to protect the rubbing elements of the hydraulic system. High-quality hydraulic oil must necessarily have certain important properties: be resistant to foaming, resist oxidative processes, not enter into chemical interactions with hydraulic system materials, have a low freezing point and a high ignition temperature, or not be flammable at all. Different grades of hydraulic oils differ in the following characteristics: pour point and fire point, corrosive effect on metal, specific gravity of contaminants and water, acid number, oxidation stability, viscosity index and kinematic viscosity. The reliability of hydraulic equipment is largely determined by the compatibility of oils and seal materials. The higher the compatibility, the less likely the equipment to leak and cause oil leaks.

Published: June 2023

Purpose: Analysis of modern approaches to dosimetric support of radionuclide therapy at the technological stages of dosimetric planning, hospitalization in a hospital and evaluation of treatment eծectiveness.

Material and methods: A comparative analysis of the methodological specifics of the dosimetric support of radionuclide therapy with the introduction of radiopharmaceuticals into the body and conventional radiation therapy using sealed sources of ionizing radiation was carried out.

Two methodically different approaches to dosimetric planning of the level of internal exposure from a radiopharmaceutical introduced into the patient’s body are considered.

The features of radiation monitoring are discussed both for the patient’s stay in the radionuclide therapy department and for safe discharge from the department for others, and for the solid and liquid radioactive waste being removed.

A comparative analysis of the functionality of various criteria for assessing the long-term and short-term effectiveness of radionuclide therapy for bone metastases was carried out.

Focal absorbed doses of internal exposure are considered as one of the criteria, for the determination of which a simplified method for their calculation is proposed based on quantitative data from SPECT/CT scanning of an X-ray phantom and a real patient who has been injected with a β-γ-emitting therapeutic radiopharmaceutical.

Results: On a clinical example of radionuclide therapy with 177Lu-PSMA-617 in a patient with stage 4 prostate cancer, dose estimates of internal irradiation of foci with β-particles were obtained. Calculations were made for bone metastases of 7 localizations in dynamics for each of the 5 fractions of the course of radionuclide therapy. It is shown that the total focal doses for 5 fractions of internal exposure vary from 70.6 to 116.8 Gy for different foci, which corresponds to the literature data obtained by more accurate methods of dosimetry of internal exposure. The obtained dosimetric data were compared with efficacy estimates based on metabolic, hematological, hormonal and biochemical parameters, as well as on the tumor marker PSA.

Conclusion: In contrast to conventional radiation therapy, dosimetric support for planning and evaluating the effectiveness of treatment has not yet become the fundamental methodological basis of modern radionuclide therapy.

Published: June 2023

Purpose: To study the impact of 68Ga-DOTATATE PET/CT on the treatment tactics of metastatic pancreatic neuroendocrine tumors (pNETs).

Material and methods: 208 68Ga-DOTATATE PET/CTs enrolled in 50 patients. Each patient underwent 68Ga-DOTATATE PET/CT two to ten times (median 4.2Դ2.2). At the time of the first study, the diagnosis of pNET was confirmed histologically and immunohistochemically in all patients. CT and MRI, as well as assessment of biochemical recurrence (serotonin and chromogranin-A levels exceeding the reference intervals) performed in all patients within one month before the next PET/CT. The results of all the listed studies in the detection of recurrent metastatic pNETs compared.

Results: At the first 68Ga-DOTATATE PET/CT, metastases were detected in 46 patients out of 50 (92 %). At the same time, prior to the first PET/CT, CT and MRI revealed tumor foci only in 34 patients (68 %). Thus, compared with routine imaging methods, additional tumor foci detected in 12 patients (24 %). Among all 208 PET/CT examinations, 166 results were positive (79.8 %). According to the results of all CT and MRI studies, tumor foci diagnosed in 117 cases (56.3 %). Compared to CT and MRI, additional tumor foci detected in 49  studies (23.6  %). Metastases on PET/CT detected in 43 studies, despite the absence of biochemical recurrence. On PET/CT, pNETs recurrence was detected in six patients versus three on CT and MRI. Tumor progression — in 10 patients versus five on CT and MRI.

Conclusion: We revealed the influence of 68Ga-DOTATATE PET/CT on the management of patients in the absence of other signs of disease recurrence or progression. 68Ga-DOTATATE PET/CT in combination with CT and MRI contributes to earlier diagnosis of recurrent metastatic pNETs.

Bu araştırma, Carl Christoph Lörcher'in Ankara'nın ilk planında (1924-25) önerdiği ‘meydanlar silsilesinin’ önemli bir parçası olan Millet (Ulus) Meydanı'na odaklanmaktadır. Araştırma resmî belgeler ve arşivler, gazete kupürleri, kişisel hatıratlar, biyografiler ve romanlar üzerinden betimsel analizlere dayanmaktadır. Bugünkü Atatürk Bulvarı, İzmir ve Tuna Caddelerinin kesiştiği noktada yer alan Millet Meydanı, Jansen Planı’nda (1932) iptal edilmesine rağmen, ada düzenin devamlılığı ve çevresinde sembolik mekânların toplanması ile Yenişehir'in en önemli kamusal odaklarından biri haline gelmiştir. Çalışma, meydanın Lörcher’in öngördüğü noktada adeta gizil bir ‘düğüm’ gibi varlığını sürdürdüğünü göstermektedir. Bununla birlikte, Erken Cumhuriyet döneminde Ankara’da yaşanan mekânsal karar verme süreçlerinin zorlu ve çok katmanlı yönlerini göstermekte, kamusal mekân ve yer olgularının girift birlikteliğini ortaya koymaktadır. Daha da önemlisi, Yenişehir’in belki de en önemli kayıp değerlerinden biri olan Millet Meydanı'nın hikayesini gün yüzüne çıkarmıştır.

Published: June 2023

Wyniki badań pochodzą z doświadczenia polowego przeprowadzonego w latach 2004–2006 w Rolniczej Stacji Doświadczalnej Zawady należącej do Akademii Podlaskiej w Siedlcach. Doświad¬czenie założono jako dwuczynnikowe w układzie split-plot w trzech powtórzeniach. W doświad¬czeniu badano dwa czynniki: I. czynnik — odmiany ziemniaka: Wiking, Mors, Żagiel. II. czynnik — insektycydy stosowane do zwalczania stonki ziemniaczanej: 1. Obiekt kontrolny, bez insektycydów, 2. Actara 25 WG w dawce 0,08 kg·ha-1, 3. Regent 200 SC w dawce 0,1 dm3·ha-1, 4. Calypso 480 SC w dawce 0,05 dm3·ha-1, 5. Calypso 480 SC w dawce 0,075 dm3·ha-1, 6. Calypso 480 SC w dawce 0,1 dm3·ha-1. Celem badań było określenie wpływu wybranych insektycydów stosowanych do zwalczania stonki ziemniaczanej na plon oraz jego strukturę. Masa bulw pod jedną rośliną jest cechą niezwykle ważną, gdyż decyduje o wydajności ziemniaka z jednostki powierzchni. Sposoby zwalczania stonki ziemniaczanej w istotny sposób różnicowały masę bulw z jednej rośliny. Największą wartość omawianej cechy zanotowano na obiekcie, na którym zastosowano preparat Calypso 480 SC w dawkach 0,075 i 0,1 dm3·ha-1, najmniejszą zaś z obiektu kontrolnego. Również w istotny sposób wartość tej cechy różnicowały odmiany. Największą masę bulw pod jedną rośliną otrzymano u odmiany Mors (średnio 683,4 g), zaś najmniejszą u odmiany Żagiel (535,7 g). Obliczenia statystyczne nie wykazały istotnego wpływu sposobów zwalczania stonki ziemniaczanej oraz odmian na liczbę bulw pod jedną rośliną. Jednakże największą liczbę bulw z jednej rośliny uzyskano z obiektów 1. (obiekt kontrolny) i 2. (Actara 25 WG w dawce 0,08 kg·ha-1), natomiast najmniejszą z obiektu 6. (Calypso 480 SC w dawce 0,1 dm3·ha-1).

Published: June 2023

W pracy przedstawiono wyniki badań z lat 2004–2007 mające na celu ocenę wartości nawozowej wsiewek międzyplonowych stosowanych w uprawie ziemniaka jadalnego odmiany Syrena. W doświadczeniu badano następujące kombinacje nawożenia wsiewką międzyplonową: obiekt kontrolny (bez nawożenia wsiewką międzyplonową), obornik, koniczyna biała, koniczyna biała + życica wielokwiatowa, życica wielokwiatowa. W biomasie wsiewek międzyplonowych oznaczono zawartość suchej masy i makroelementów (N, P, K, Ca i Mg). W pierwszym roku po nawożeniu wsiewkami międzyplonowymi uprawiano ziemniaki jadalne odmiany Syrena. Podczas zbioru ziemniaka określono plon ogólny świeżej masy bulw, a po zbiorze strukturę plonu bulw. Uzyskane wyniki badań pozwalają stwierdzić, iż spośród badanych wsiewek międzyplonowych najwięcej suchej masy wprowadziła do gleby życica wielokwiatowa, a także mieszanka koniczyny białej z życicą wielokwiatową, a makroelementów koniczyna biała oraz mieszanka koniczyny białej z życicą wielokwiatową. Nawożenie wsiewkami międzyplonowymi, z wyjątkiem życicy wielokwiatowej w pełni zastępuje obornik w uprawie ziemniaka jadalnego. Największy udział frakcji bulw jadalnych i sadzeniaków, a najmniejszy udział bulw małych w plonie odnotowano na obiektach nawożonych mieszanką koniczyny białej z życicą wielokwiatową oraz koniczyną białą.

W pracy przedstawiono wyniki badań z lat 2003–2006 mające na celu określenie wpływu wsiewek międzyplonowych i międzyplonów ścierniskowych oraz słomy jęczmiennej na wybrane elementy składu chemicznego bulw ziemniaka. W doświadczeniu badano dwa czynniki. I. Nawożenie międzyplonem: obiekt kontrolny (bez nawożenia międzyplonem), obornik, wsiewka międzyplonowa (komonica zwyczajna, komonica zwyczajna + życica wielokwiatowa), międzyplon ścierniskowy (rzodkiew oleista). II. Nawożenie słomą: bez słomy, ze słomą. W pierwszym roku po zastosowaniu nawożenia organicznego uprawiano ziemniaki jadalne odmiany Fianna. W pobranych próbach bulw ziemniaka oznaczono zawartość: skrobi, cukrów redukujących, sumy cukrów oraz białka ogólnego. Otrzymane wyniki badań pozwalają stwierdzić, iż nawożenie międzyplonem istotnie modyfikowało zawartość skrobi, cukrów redukujących, sumy cukrów oraz białka ogólnego, a nawożenie słomą tylko zawartość skrobi i białka ogólnego w bulwach ziemniaka. Najwyższą zawartością skrobi wyróżniały się ziemniaki nawożone mieszanką komonicy zwyczajnej z życicą wielokwiatową oraz rzodkwią oleistą w kombinacjach bez słomy lub ze słomą, a białka ogólnego ziemniaki nawożone komonicą zwyczajną i komonicą zwyczajną ze słomą. Najniższą zawartość cukrów redukujących i sumy cukrów odnotowano w ziemniakach nawożonych mieszanką komonicy zwyczajnej z życicą wielokwiatową z dodatkiem słomy lub bez słomy.
Wpływ napromieniowania mikrofalami sadzeniaków ziemniaka na plonowanie roślin
Authors: Jakubowski Tomasz
Published: June 2023

W latach 2007–2009 przeprowadzono doświadczenie poletkowe w którym badano wpływ mocy generatora (100–300 W) i czasu (5–30 s) napromieniowania mikrofalami (2,45 GHz) zastosowanych do stymulacji sadzeniaków na plonowanie roślin ziemniaka bardzo wczesnej odmiany Felka Bona. Przy przyjętych w doświadczeniu parametrach pracy generatora mikrofal stwierdzono istotny wpływ całkowitej dawki napromieniowania mikrofalami na masę plonu bulw ziemniaka spod jednej rośliny. Nie stwierdzono natomiast aby tożsame wartości dawek całkowitych (uzyskanych z różnych wartości mocy urządzenia generującego mikrofale i czasu ekspozycji sadzeniaków) miały taki sam wpływ na plonowanie roślin ziemniaka.

Published: June 2023

Celem pracy było określenie zawartości akrylamidu we frytkach po I i II stopniu smażenia oraz barwy gotowego produktu w zależności od zawartości cukrów redukujących w bulwach ziemniaka trzech odmian. Stwierdzono, że zawartość cukrów redukujących w ziemniakach badanych odmian miała wpływ na ilość wytworzonego akrylamidu we frytkach. Z ziemniaków odmiany Innovator o najniższej zawartości cukrów redukujących uzyskano frytki o najmniejszej ilości akrylamidu w porównaniu z produktami z pozostałych odmian. Półprodukt (frytki po I stopniu smażenia) zawierały dziewięć razy mniej akrylamidu (średnio 40 μg·kg-1) niż frytki gotowego spożycia (średnio 360 μg·kg-1). Frytki sporządzone z ziemniaków odmiany Innovator o najniższej zawartości cukrów redukujących odznaczały się najjaśniejszą barwą (wartość „L” = 70) w porównaniu z pozostałymi próbami.

Authors: Matyjaszczyk Ewa
Published: June 2023

Przedstawiono zmiany w rejestracji środków stosowanych w ochronie ziemniaka w Polsce oraz zmiany w dostępności ich substancji aktywnych. Liczba zarejestrowanych w Polsce środków ochrony roślin w pierwszych pięciu latach członkostwa w Unii spadła o prawie 100, jednak w 2009 roku odnotowano jej wzrost. Według stanu na koniec roku 2009 w Polsce zarejestrowane były 132 środki mające zastosowanie w ochronie ziemniaka. Największą grupę stanowiły fungicydy (55 środków), kolejną — insektycydy (34 środki), herbicydy (33 środki) i pozostałe (10). Liczba substancji aktywnych stosowanych w ochronie ziemniaka spadła w ostatnich latach o około 30%. Główną przyczyną tych zmian była konieczność dostosowania się do przepisów Unii Europejskiej.
