Opis:
Background The process of treating infertility using the in vitro method can affect both physical and mental health. The study aims to determine the impact of trying to conceive using the in vitro method on the quality of life and psychological well-being of women. Material and methods Respondents completed an online questionnaire. The experiment was conducted from July to December 2023 and 100 women involved. It was based on an questionnaire created by the authors and questionnaire tools: Fertility Quality of Life, Patient Health Questionnaire (PHQ-9) , and selected subscales from Berlin Social Support Scales (BSSS). Results Among the respondents, 85% of women do not have children.The average age of the women studied was 34 years, while the average number of years of infertility treatment was 6 years. Respondents rate their quality of life the best in the area of relationship, but the worst in the area of emotions. More than 80% of respondents were at risk of developing depressive disorders of varying severity. Nevertheless, the vast majority are satisfied with the support they receive. Conclusions Negative emotions that accompany women during in vitro process significantly affect their quality of life. They also contribute to an increased risk of mental disorders.

Opis:
Artykuł obejmuje zagadnienie dopuszczalności postmortalnego przeniesienia zarodków oraz konsekwencji filiacyjnych i prawnospadkowych zabiegu medycznego, w którego następstwie dochodzi do urodzenia dziecka. Autorzy dostrzegają wątpliwości wiążące się ze stosowaniem szczególnej regulacji zawartej w ustawie o leczeniu niepłodności i jej konsekwencji w prawie spadkowym. Wiąże się to z tym, że pomiędzy powstaniem zarodka poza organizmem kobiety i jego pozostawaniem poza tym organizmem mogą zaistnieć zdarzenia, których skutki dostrzegalne będą zarówno w sferze prawnej podmiotów poddających się leczeniu niepłodności, jak i potencjalnie w sferze mającego się narodzić dziecka. Zdarzenia te mogą mieć postać zdarzeń naturalnych, niezależnych od woli (zdarzenia sensu stricto), a także zdarzeń konwencjonalnych, skutkujących np. wycofaniem zgody zainteresowanych podmiotów na przeniesienie zarodka do organizmu kobiety. Przedmiotem analiz pozostają konsekwencje filiacyjne oraz skutki prawnospadkowe w sytuacji zdarzeń naturalnych wiążących się ze śmiercią mężczyzny, który był dawcą komórek rozrodczych w ramach dawstwa partnerskiego, oraz mężczyzny, który wyraził zgodę na zapłodnienie żony anonimowym nasieniem.
The article covers the issue of the admissibility of postmortal embryo transfer and the filiation and inheritance consequences of a medical procedure that results in the birth of a child. The authors note doubts related to the application of the specific regulation contained in the Infertility Treatment Act and its consequences in inheritance law. This is due to the fact that between the creation of the embryo outside the woman's body and its remaining outside the body, events may occur, the effects of which will be noticeable both in the legal sphere of entities undergoing infertility treatment, and potentially in the sphere of the child to be born. These events may take the form of natural events, independent of will (events in the strict sense), as well as conventional events, resulting in, for example, the withdrawal of the consent of interested entities to transfer the embryo into the woman's body. The subject of the analyzes are the filiation consequences and legal inheritance consequences in the event of natural events involving the death of a man who donated reproductive cells as part of a partnership donation and a man who consented to his wife's fertilization with anonymous sperm.

Opis:
Ziarno pszenżyta charakteryzuje się wysoką wartością paszową, ale stwarza również możliwości wykorzystania go w celach konsumpcyjnych, gdzie może być wykorzystywane jako surowiec do produkcji chleba. Wartość wypiekowa związana jest z parametrami technologicznymi, które powinny cechować się optymalnymi wartościami. Są one determinowane, m. in., nawożeniem mineralnym, jak i naturalnym. W związku z powyższym przeprowadzono 2. czynnikowe badania, założone metodą losowanych podbloków. Materiał doświadczalny stanowiło ziarno pszenżyta ozimego. Czynnikami badawczymi były: nawożenie naturalne (obornik) i aplikacja mikroelementami (Cu, Zn, Mn, Cu+Zn+Mn). Celem było sprawdzenie wpływu wyżej wymienionych czynników oraz ich interakcji na wartość technologiczną ziarna. Najwyższą wartość liczby opadania, w stosunku do obiektu kontrolnego, stwierdzono po zastosowaniu 30 t⸱ha-1 obornika oraz na obiekcie, gdzie aplikowano dolistnie łącznie miedź, cynk i mangan. Stwierdzono również, że nawożenie obornikiem i dolistne nawożenie Cu, Zn, Mn oraz łączne ich zastosowanie powodowało średnio istotny wzrost wartości cech kompleksu białkowego ziarna pszenżyta (białko, gluten, sedymentacja) i objętości pieczywa, w stosunku do kontroli. Wskaźniki kompleksu enzymatycznego i białkowego były istotnie determinowane współdziałaniem nawożenia naturalnego i aplikacją mikroelementami. Najkorzystniejsze wartości tych cech stwierdzono po zastosowaniu obornika oraz dolistnie cynku.
Triticale grain has a high feed value, but it can also be used for consumption purposes, where it can be used as a raw material for the production of bread. The baking value is related to the technological parameters, which should be characterized by optimal values. They are determined, among other things, by both mineral and natural fertilisation. Therefore, two-factor research was carried out using the randomized subblock method. The experimental material consisted of winter triticale grain. The research factors were: natural fertilisation (manure) and foliar spraying with selected microelements (Cu, Zn, Mn, Cu+Zn+Mn). The aim was to check the influence of the abovementioned factors and their interactions on the technological value of grain. The highest values of the falling number, in relation to the control objects, were found after the application of manure and in the object where a total of copper, zinc and manganese were applied foliarly. It was found that manure fertilisation and foliar fertilisation with copper, zinc, manganese and their combined application resulted in an average in the value increase of features of the protein complex of triticale (protein, gluten, sedimentation) and bread volume, compared to the control. The indicators of the enzymatic and protein complex were significantly determined by the interaction of natural fertilisation and the application of microelements. The most favorable values of these features were found after the application of manure and foliar zinc.

Ocena jego niedoborów w uprawach kukurydzy jest przedmiotem badań naukowych. W artykule zaprezentowano wyniki pomiarów w kontrolowanych warunkach laboratoryjnych wskaźników teledetekcyjnych kukurydzy uprawianej w wariantach nawożenia 0-150 kg·N/ha. Zaproponowana metoda oceny niedoboru azotu z wykorzystaniem sensora Crop Circle pozwala na autonomiczne sterowanie precyzyjnym nawożeniem doglebowym w projektowanym rozwiązaniu robota polowego.
Nitrogen is an important macronutrient of biomass because it plays an important role in metabolic processes, protein production, amino acid synthesis, enzymes, hormones and is a component of chlorophyll. The assessment of its deficiencies in maize crops is the subject of scientific research. The article presents the results of measurements in controlled laboratory conditions of remote sensing indices of maize cultivated in fertilization variants of 0-150 kg·N/ha. The proposed method of assessing nitrogen deficiency using the Crop Circle sensor allows for autonomous control of precise soil fertilization in the designed solution of a field robot.

Opis:
The mealybug, Phenacoccus solenopsis (Hemiptera: Coccomorpha: Pseudococcidae), is one of the main pests attacking maize plants in Egypt. Field trials were carried out in the maize field to assess the influence of irrigation periods and potassium fertiliser rates on the mealybug (P. solenopsis) population estimates, vegetative growth, resulting yield, and its components for the maize cultivar (‘Single-Hybrid 168 Yellow’) in the Luxor Governorate, Egypt. Results revealed that unfertilised plants irrigated every seven days had higher pest population densities than other treatments over the two seasons. The fertilised treatments at 114 kg K2O∙ha -1 that received water every 10 days had the smallest population of P. solenopsis in every season. Data during the two seasons (2021 and 2022) revealed that the maize to which potassium fertiliser was added by 114 kg K2O∙ha -1 and irrigated every 10 days had vegetative growth (plant height, diameter, and number of green leaves per plant), yield and its components (average ear length, ear weight, number of grains per ear, weight of 1000 grains, and grain yield) significantly increased as compared to those of the plants that were irrigated every 7 days and without adding fertiliser. A higher dose of potassium fertiliser reduces the infestation of P. solenopsis but causes an increment of maize vegetative growth. This affects the final yield. This information aids farmers in comprehending the good agronomic techniques of maize plants to decrease the infestation of mealybugs and increase the yield.

Opis:
The research was carried out on a farm located in Mal- ice (Werbkowice municipality), in the years 2014–2016. The aim of the study was to evaluate the profitability and marginal eco- nomic efficiency of sulfur fertilization of spring wheat at vari- ous levels of nitrogen fertilization. Production value, direct costs and production profitability were assessed, as well as the mar- ginal economic efficiency. On average, the highest grain yield was achieved on the object fertilized with nitrogen at a dose of 150 kg. ha-1 and sulfur in the amount of 40 kg S ha-1. The highest value of direct surplus and, at the same time, the highest profit- ability of production was obtained after nitrogen application in the dose of 100 kg N ha-1. Increasing the nitrogen dose from 50 to 100 kg ha-1 resulted in a significant increase in the grain yield and the achievement of the most favourable marginal economic efficiency index. Among the objects fertilized with nitrogen, the most advantageous in terms of production profitability and mar- ginal economic efficiency was the use of this element in the dose of 100 kg N ha-1. The use of sulfur in the fertilization of spring wheat in the dose of 40 kg S ha-1 slightly improved the fertiliza- tion efficiency in the objects with 50 and 150 kg ha-1. Among the objects fertilized with nitrogen, the most advantageous in terms of production profitability and marginal economic efficiency was the use of this element in the dose of 100 kg N ha-1.

Opis:
The effects of bacterial and fungal inocula on the growth, yielding, and nutritional status of apple trees was evaluated in 3-years experiment (2018 - 2020). The experiment included the following treatments: (i) control (unfertilized soil), (ii) no fertilization + soil application of fungi, (iii) no fertilization + soil application of bacteria. The mixture of beneficial fungi contained two species: Aspergillus niger and Purpureocillium lilacinum. The mixture of beneficial bacteria contained three strains of Bacillus (Bacillus sp., Bacillus amyloliquefaciens and Paenibacillus polymyxa). The application of beneficial microorganisms (especially bacterial strains) to the soil (without additional mineral fertilization) enhanced the growth of the apple trees. In the third year of the study (2020), the trees grown in the plots inoculated with bacteria bloomed the most intensively. Plant nutritional status (expressed as concentrations of elements in leaves) was not affected by the application of the bacterial strains or filamentous fungi. The stronger growth of trees in the plots where the bacteria were used was likely related not so much to the nutritional status of the trees, but to the mitigation of the influence of the negative factors that cause the replant disease.

Opis:
Soil acidification, fertility depletion, food insecurity, and environmental pollution all are consequences of the extensive use of chemical fertilizers (CF) in intensively managed plantations. Recent studies have shown that incorporating organic manure (OM) to partially replace CF can help to maintain productivity and soil health. There are no reports on integrated fertilizer management of Zanthoxylum armatum, for optimal ecological services and economic profitability. A pot experiment with Z. armatum was performed to investigate the possibility of incorporating OM in reducing CF use, enhancing soil fertility, and increasing plant growth. For this, seven treatments were designed: NPK, PK, NP, NK, OM, MNPK (50%NPK+50%OM), and control (CK, no fertilizer application). The results showed that NPK application significantly (P < 0.05) increased plant growth, soil nitrate-N, ammonium-N and available K compared to CK. However conventional CF application induced soil acidification. OM application raised the soil pH from 5.50 (CK) to 6.58 and significantly enhanced soil fertility by increasing alkali-hydrolysable N (2.3 times), ammonium-N (1.4 times), available P (4.3 times), the activity of invertase (1.5 times), catalase (2.8 times), acid phosphatase (1.5 times), and count of soil culturable microbes (2.9 times) compared to CK. Conversely, sole OM application did not result in optimum plant growth. Integrating OM with NPK (MNPK), on the other hand, not only provided the highest growth comprehensive value (0.84), but also substantially higher soil fertility comprehensive value (0.71) than traditional CF treatments. Correlation analysis also indicated a positive and significant correlation between soil microbes, enzyme activities and available nutrients. Therefore, OM+NPK could be an optimum measure to get maximum benefits regarding soil fertility, growth of Z. armatum, fertilizer savings and sustainable agroecology.

Opis:
The paper summarises the results of the comprehensive scientific research carried out in the form of a two-factor stationary experiment (5 primary tillage systems × 3 fertilization systems) with rotation (2016–2020) of cereal crops (winter wheat – grain maize – spring barley – soybean) in grey forest fine sand and light loam soil. The effectiveness of the tested agricultural production method has been proven by the amplitudes of the actual cropping capacities: winter wheat – 2.80–5.00 t∙ha–1; grain maize – 4.16–8.89 t∙ha–1; spring barley – 1.78–4.45 t∙ha–1; soybean – 1.02–3.17 t∙ha–1. The rehabilitation of the physical, agrochemical and biological status of the edatope and the consolidation of the physiological processes in the grain cenoses achieved by the systemic approach to the soil tillage and fertilisation have provided for an increase in the natural biological potential of the plough land by a factor of 1.3–1.8 (from 2.96 to 5.21 t∙ha–1 of grain units, units for the equivalent measuring of different plant cultivation products). Factographic justification has been provided for the environmental, technological and technical-and-economic feasibility of implementing agronomic technologies based on the adaptive combination of mouldboard and non-mouldboard tillage (to a depth of 6–45 cm) and organic and mineral fertilization system (6.5–7.0 t∙ha–1 of plant cultivation by-products + N70P58K68). In this case, the effective fertility of an area unit in crop rotation reaches 5.72 t∙ha–1 in grain units, the production cost of raised grain – 117 €∙t–1, the earning capacity – 788 € (ha∙year) –1, the level of plant cultivation profitability – 139%. In the comparable alternatives of the system-based soil tillage (every-year ploughing, subsurface blade tillage and especially tillage with disk implements), the indices estimated above are significantly lower.

Opis:
The aim of the studies was to determine the effect of fertilization with mineral fertilizers and the digestate from an agricultural biogas plant on selected plant parameters. In 2016 a three-year two-factor field experiment was established, where the first factor was the fertilization variant and the second factor was the plant species (triticale, maize, sorghum). Fertilization was carried out on two dates: pre-sowing and top-dressing. The first variant consisted of nitrogen fertilization, exclusively mineral; in the second variant, plants were fertilized before sowing with di- gestate, and then top-dressed with mineral fertilizer; while in the third variant, in both terms, plants were fertilized with digestate. The quality of biomass was examined in terms of its chemical composition and as a raw material for biogas production. Regard- less of the applied variant of fertilization, the plants tested were equally well supplied with nitrogen. Fertilization with digestate increased the C:N ratio in the biomass of sorghum (which de- viated from the optimal value for effective anaerobic fermenta- tion process), lowered the crude fibre content in the biomass of triticale, but also increased the content of cellulose in triticale. Fertilization with digestate makes it possible to give up mineral nitrogen fertilization, without negative influence on the quality and chemical composition (including crude fibre and lignin frac- tions) of triticale and maize used as biogas substrates.

Opis:
The study presents the results of a 3-year field study, whose aim was to assess the effect of sowing and NP fertilizer application method on dry matter (yield) accumulation at the BBCH 15/16 stage of two different types (traditional and stay-green) of maize varieties. It was found that the nutritional status of maize in the stands rich in nutrients may only incidentally (depending on years) show a reaction to variety selection and row application of NP fertilizers, improving the values of nitrogen nutrition indices. Physiological indices of the plants’ status at the BBCH 15/16 stage showed a significant, albeit variable over the years, response to variety selection and the row application of NP fertilizers. The negative effect of the sowing method was revealed incidentally.
W pracy przedstawiono wyniki 3-letnich badań polowych, których celem była ocena wpływu sposobu siewu i aplikacji nawozu NP na gromadzenie suchej masy (plon) w fazie BBCH 15/16 przez dwa różne typy (tradycyjna i stay-green) odmian kukurydzy. Stwierdzono, że stan odżywienia kukurydzy w stanowiskach zasobnych w składniki pokarmowe tylko incydentalnie (od lat) może wykazać reakcję na dobór odmiany, jak i rzędowe stosowanie nawozów typu NP poprawiając wartość wskaźników odżywienia azotem. Wskaźniki fizjologiczne stanu roślin w stadium BBCH 15/16 wykazują istotną, aczkolwiek zmienną w latach, reakcję na dobór odmiany i rzędowe stosowanie nawozów NP. Ujemne działanie sposobu siewu ujawnia się incydentalnie.

The aim of the study was to determine the effect of foliar fertilizers containing macro- and microelements, and used in the form of chelates, on the content of macroelements in tubers of several potato varieties. The study was based on a 3-year (2013-2015) field experiment conducted in Haczow (49°39′40″N, 21°53′49″E), on brown, slightly acidic soil. The experiment was established using the method of random subblocks, where the first order factors were foliar fertilization treatments with the following fertilizers: Fortis Duotop Zn Mn + Fortis Aminotop (A), Fortis B Mo + Ferti Agro (B), Fortis Zn Mn + Fortis B Mo (C) and the control object, without foliar fertilization. The second order factors were 4 potato varieties belonging to different classes of earliness (Agnes, Jelly, Viviana, Vineta). Foliar application of all fertilizer combinations contributed to an increase in the magnesium content, while the application of Fortis B Mo + Ferti Agro fertilizers increased the nitrogen and potassium content. Genetic traits differentiated the content of macroelements. Tubers of the cultivar Jelly were characterized by the largest accumulation of phosphorus, potassium, magnesium and calcium, while the Viviana cultivar had the smallest amounts of phosphorus, potassium, calcium. The meteorological conditions in the years of the experiment modified the content of macroelements. Under the dry summer conditions but very wet September in 2013, the tubers accumulated most magnesium and calcium, but contained the least nitrogen, phosphorus and potassium. With excess precipitation in 2014, the tubers were found to contain the most phosphorus, potassium and calcium, while in the dry 2015 year, with a significant shortage of precipitation during the potato growing season and air temperature higher than the long-term average, the tubers accumulated the highest nitrogen but the lowest calcium amounts.

Opis:
The article deals with effect the use of organic (biohumus) and mineral (biochar) fertilizers based on the products of chicken vital activity on changing the fertility of technogenic sod-podzolic soils exposed to constant and unstable magnetic fields. The germination and growth dynamics of grasses and onions were investigated. The rational rate of introduction of the studied fertilizers into the technogenic soil is determined. Running (RMF) and direct (DMF) magnetic fields were applied in two ways: with fertilizers added and without fertilizers added. It has been established that the effect of preliminary magnetization of technogenic soil has a significant effect on lawn grass germination and the length of onion feathers, which are more than twice the height when exposed to the RMF, as compared with DMF. The effect of RMF on grass germination was also twice as high for DMF, when fertilizers were added. The DMF magnetization and biohumus helps to increase the grass sprout height by 10–20%. Onion sprouts were higher in two cases: DMF and biohumus; RMF and biochar. The influence of the factor of fertilizer type has a significant effect in 30–40% of cases, whilst at a spread rate of more than 5%, significant chemical activity of biochar negatively affects the germination of both grass and onion.
