Wpływ zróżnicowanej rozstawy rzędów i ilości wysiewu na rozwój i plonowanie soi (Glycine max (L.) Merrill). Cz. III. Ekonomiczne aspekty produkcji nasion
Get PDFIn Poland, the production of soybean seeds fluctuates significantly from year to year due to the instability of yields and variable profitability of cultivation. The aim of the research was to determine the profitability of soybean (Glycine max (L.) Merrill) production under the influence of different row spacing and the increasing number of sown seeds per 1 m2. The cost-effectiveness analysis was carried out on the basis of research results from a field experiment carried out in 2015–2017 on the experimental fields of the Institute of Agroecology and Plant Production of the University of Environmental and Life Sciences in Wrocław. Field studies were carried out on the different row spacing (15 cm, 30 cm) and sowing amount (50, 70, 90 pcs.) on the 1 m2. Own research showed that the direct costs incurred for the cultivation of soybean for seeds were shaped by the varied number of sown seeds per 1 m2, but did not depend on the row spacing used. The largest share in the structure of direct costs was the total cost of tillage operations and the cost of seed purchase, which depended on the variable number of sown seeds per area unit.W Polsce produkcja nasion soi ulega znacznym wahaniom w latach ze względu na niestabilność plonowania oraz zmienną opłacalność prowadzenia uprawy. Celem podjętych badań było określenie opłacalności produkcji nasion soi (Glycine max (L.) Merrill) pod wpływem zróżnicowanej rozstawy rzędów oraz wzrastającej liczby wysianych nasion na 1 m2. Analizę opłacalności przeprowadzono na podstawie wyników badań pochodzących z doświadczeń polowych przeprowadzonych w latach 2015–2017 na polach doświadczalnych Instytutu Agroekologii i Produkcji Roślinnej Uniwersytetu Przyrodniczego we Wrocławiu. Doświadczenia polowe założono w układzie split-plot, w czterech powtórzeniach, z dwoma czynnikami zmiennym: zróżnicowaną rozstawą rzędów (15 cm, 30 cm), zróżnicowaną liczbą wysiewanych nasion (50, 75, 90 nasion na 1 m2). Badania własne wykazały, że koszty bezpośrednie poniesione na uprawę soi na nasiona były kształtowane przez zróżnicowaną liczbę wysiewanych nasion na 1 m2, natomiast nie zależały od zastosowanej rozstawy rzędów. W strukturze kosztów bezpośrednich największy udział miał łączny koszt zabiegów uprawowych i koszt zakupu materiału siewnego uzależniony od zmiennej liczby wysiewanych nasion na jednostkę powierzchni
Preferencje młodych rolników w zakresie informacji rynkowej
Get PDFIn the conditions of a market economy, farmers have needs in terms of knowledge and vocational skills. The aim of the study was to identify the needs of young farmers in relation to market information. In order to implement the topic, survey research was conducted among 90 farmers from the Siedlce district in the Masovian Voivodeship. Young farmers who have only recently started farming have little experience and often face many difficulties. In addition to needs in the field of general agricultural consultancy and business-organization consultancy, there is a need for advice on product development and marketing. They attach great importance to obtaining information and solving their problems through direct contact with advisors, both from private companies and agricultural advisory centres.W warunkach gospodarki rynkowej występują u rolników potrzeby w zakresie wiedzy i umiejętności zawodowych. Celem opracowania była identyfikacja potrzeb młodych rolników w odniesieniu do informacji rynkowej. W celu realizacji tematu przeprowadzono badania ankietowe, którymi objęto 90 rolników z powiatu siedleckiego w województwie mazowieckim. Młodzi rolnicy prowadzący swoje gospodarstwa od niedawna, posiadający małe doświadczenie, borykają się niejednokrotnie z wieloma trudnościami. Oprócz potrzeb w zakresie doradztwa ogólnorolniczego i ekonomiczno-organizacyjnego pojawia się zapotrzebowanie na doradztwo w zakresie zagospodarowania i zbytu produktów rolniczych. Przywiązują oni dużą rolę w pozyskanie informacji i rozwiązywanie swoich problemów przez bezpośredni kontakt z doradcą, tak z firm prywatnych, jak również z ośrodków doradztwa rolniczego
Formulating evidence-based design guidelines for therapeutic gardens tailored to elderly populations: a synthesis of reminiscence and preference studies
Get PDFGardens emerge as powerful catalysts for enhancing the well-being of the older generation. The design of a garden plays a significant role in engagement with such an environment. The investigation aimed to determine features integral to the garden for older adults to be applied as design guidelines for therapeutic gardens serving the elderly. A mixed quantitative-qualitative approach was used with a questionnaire focused on eliciting insights into the garden experiences. The respondents comprised individuals from Care Homes and Senior Activity Centres. The results revealed the importance of childhood gardens and associated memories of the elderly. Consequently, the conceptualisation of a garden tailored to the needs of older adults highlights relaxation. A garden should facilitate passive engagement with nature and active involvement in the nurturing of plant life. Botanical preferences encompass a diverse array of flora: roses, tulips, and peonies in the floral domain; tomatoes, onions, and carrots within the vegetables; and apples, pears, and plums within the realm of fruits.Gardens emerge as powerful catalysts for enhancing the well-being of the older generation.

Impact of N fertilization and cultivar on amaranth nutrients and soil health
Get PDFThe purpose of this study was to assess the effects of nitrogen (N) fertilization and cultivar on vitamin C content, total antioxidant capacity (TAC), and catalase (CAT) activity in amaranth leaves, as well as in the rhizosphere and non-rhizosphere soil. For this purpose, a 3-year split-plot field experiment was conducted, which included the following factors: N fertilization (kg ∙ ha–1: N0 – control, N1 – 60, N2 – 90, N3 – 120, N4 – 150), amaranth cultivars (‘Rawa’ and ‘Aztek’) and developmental stages (BBCH 13, BBCH 16, BBCH 19). The factor that most significantly differentiated the vitamin C content in the leaves was the cultivar, followed by the development stage, N fertilization, and weather conditions. The cultivar ‘Aztek’, stage BBCH 13, N3 fertilization, and weather conditions during the last year of the experiment gave the best results in this regard. CAT activity in the leaves significantly depended on N fertilization and developmental stage. It increased with the higher N dose and decreased with plant development. The TAC of the leaves depended only on the developmental stage and weather conditions. The highest TAC was observed at BBCH 13 and the third year of the study. CAT in the rhizosphere significantly depended on N fertilization, cultivar, and developmental stage, while in the non-rhizosphere zone, it depended on N fertilization, developmental stage, and weather conditions. This study is an essential addition to the knowledge on the use of amaranth seed forms as a vegetable with high nutritional value and antioxidant properties, as well as the effect of this plant on soil biological properties.The purpose of this study was to assess the effects of nitrogen (N) fertilization and cultivar on vitamin C content, total antioxidant capacity (TAC), and catalase (CAT) activity in amaranth leaves, as well as in the rhizosphere and non-rhizosphere soil.

Anticancer and Cytotoxic Activities of Some Trigonella Species on MCF-7, L929 and HeLa Cell Lines
No full textTrigonella filipes Boiss, Trigonella strangulata Boiss., and Trigonella uninata Banks and Sol., are three commonly used species that grow well in Iraq's northern suburbs and are frequently consumed and used in traditional medicine. The current study was planned to assess and identify the active chemicals in these plant species, as well as to analyze their anticancer and antiprofeliration effects in rats treated with alcohol and cholesterol. Plant extracts were tested for oxidative stress index (OSI), total oxidant status (TOS), and total antioxidant status (TAS). Administration of Trigonella foenum-graecum and Trigonella monantha significantly improved these changes in diseased rats. MTT cytotoxicity test was used to investigate the cytotoxic properties of Trigonella filipes, Trigonella strangulata, and Trigonella uncinata plant extracts on three distinct cell lines in varied concentrations (1-10-100-1000 g/mL) after 24 h of incubation. The results were supported that these three plant taxa have high phytochemical compounds that have physiological effects such as inhibit cell proliferation, improving the function of liver and kidney function, and antioxidants effect.HUBAK of Harran University, Sanliurfa, TurkeyThe authors gratefully recognize the HUBAK of Harran University, Sanliurfa, Turkey for partially supporting this project and offering the best facility for research

Effects of foliar iron oxide nanoparticles (Fe 3 O 4 ) application on photosynthetic parameters, distribution of mineral elements, magnetic behaviour, and photosynthetic genes in tomato ( Solanum lycopersicum var. cerasiforme) plants
No full textThis study aims to examine the effect of foliar magnetic iron oxide (Fe 3 O 4 ) nanoparticles (IONP) application on the physiology, photosynthetic parameters, magnetic character, and mineral element distribution of cherry tomatoes ( Solanum lycopersicum var. cerasiforme ). The IONP suspension (500 mg L -1 ) was sprayed once (S1), twice (S2), thrice (S3), and four times (S4) a week on seedlings. Upon 21 days of the treatments, photosynthetic parameters (chlorophyll, carotenoids, photosynthetic yield, electron transport rate) were elucidated. Inductivelycoupled plasma -optical emission spectrometer (ICP-OES) and vibrating sample magnetometer (VSM) were used to determine the mineral elements and abundance of magnetic power in the seedlings. In addition, the RTqPCR method was performed to quantify the expressions of photosystem-related ( PsaC , PsbP6 , and PsbQ ) and ferritin-coding ( Fer-1 and Fer-2 ) genes. Results revealed that the physiological and photosynthetic indices were improved upon S1 treatment. The optimal dosage of IONP spraying enhances chlorophyll, carotenoid, electron transport rate (ETR), and effective photochemical quantum yield of photosystem II (Y(II)) but substantially diminishes non -photochemical quenching (NPQ). However, frequent IONP applications (S2, S3, and S4) caused growth retardation and suppressed the photosynthetic parameters, suggesting a toxic effect of IONP in recurrent treatments. Fer-1 and Fer-2 expressions were strikingly increased by IONP applications, suggesting an attempt to neutralize the excess amount of Fe ions by ferritin. Nevertheless, frequent IONP treatment fluctuated the mineral distribution and caused growth inhibition. Although low -repeat foliar applications of IONP (S1 in this study) may help improve plant growth, consecutive applications (S2, S3, and S4) should be avoided.Deanship of Scientific Research (DSR) funds of Imam Abdulrahman Bin Faisal University (IAU) [2019-058-IRMC]The Deanship of Scientific Research (DSR) funds of Imam Abdulrahman Bin Faisal University (IAU) have supported this study under project numbers 2019-058-IRMC
