The diverse nutrients found in sweet potato leaves, including vitamins, minerals, and antioxidants, offer a range of health benefits. The presence of carotenoids and polyphenols, both powerful health-promoting compounds, highlights their potential contribution to medical science. The main objective of this study was to ascertain essential functionals substances of antioxidant, phenolic compounds, and β-carotene in the leaves of 14 distinct sweet potato lines cultivated in open field. A comprehensive analysis of antioxidant capacity, phenolic content, and β-carotene was conducted using ABTS, Folin-Ciocalteu, and HPLC techniques, respectively. The study showed that the concentrations of total antioxidants, phenols, and β-carotene differed markedly among the leaf materials. Among the lines, SP-13 stands out with the highest concentration of phenols (124.64 mg/g dry weight), while SP-14 comes in at the opposite end with the lowest amount (62.97 mg/g dry weight) under field conditions. In the case of antioxidant content in line SP-3 showed the highest with 3.55 mg/g dry weight, while SP-14 brings up the lowest with 1.88 mg/g dry weight. Line SP-5 showed the most β-carotene (0.51 mg/g dry weight), while SP-11 had the least (0.05 mg/g dry weight). Therefore, it can be concluded that sweet potato leaves are a valuable dietary source of antioxidants, phenolic compounds, and β-carotene which have beneficial health elements.

Salih Eroğlu
Bu çalışmada çekirdekli ve çekirdeksiz nar taneleri (Punica granatum L.) ince tabaka halinde farklı sürelerde ultrason ön işlemi (US) uygulandıktan sonra 70 °C’de 1,3 m/s hava hızında kurutulmuştur. Nar tanelerinin kuruma kinetiğinin incelenmesi amacıyla literatürde çok kullanılan ancak karmaşık ve verilerin dönüştürülmesini gerektiren çok parametreli modeller yerine en çok iki parametreli modeller kullanılmıştır. Bu modeller Lewis (Newton), Page, Modifiye Page I, Weibull, Weibull I ve Modifiye Çift Terimli III modelleridir. Kurutma işlemlerini en iyi açıklayan modelin seçilmesi amacıyla hata kareleri ortalamasının kare kökü (RMSE) ve belirleme katsayısı (R2) değerleri incelenmiştir. Elde edilen sonuçlara göre çekirdekli nar tanelerinin kurutulmasını tüm işlem koşullarında en iyi Page modelinin açıkladığı belirlenmiştir. Çekirdeksiz nar tanelerinde ön işlemsiz ve 10 dakika US ön işlemli nar tanelerinin kurutulmasını en iyi açıklayan modelin Page modeli, 20 ve 30 dakika US ön işlemli nar tanelerinin kurutulmasını en iyi açıklayan modelin ise Weibull modeli olduğu belirlenmiştir. Bununla birlikte, kurutma öncesinde uygulanan farklı sürelerdeki US ön işlemlerinin çekirdekli ve çekirdeksiz nar tanelerinin kuruma sürelerini önemli ölçüde azalttığı belirlenmiştir.

Sumiaya Parvin | Md. Parvez Anwar | Md. Sojib Kabiraj | Md. Harun Rashid | Swapan Kumar Paul
In a lab experiment using seed priming, the faba bean (Vicia faba L.) seed germination and seedling development were studied. Twenty different priming techniques were utilized in the study, each comprising varying concentrations of NaOCI, CaCl2, KNO3, Manitol, PEG, KCL, H2O and a control group that received no priming. Four replications of a completely randomized design (CRD) were used in the experiment. Among the three priming treatments, there were substantial differences in the seedling growth metrics and germination rate. When 500 ppm NaOCl was used as a treatment, the highest seed germination percentage (96%) was attained. Although 100 ppm PEG had the greatest germination index (42.92), 10000 ppm NaOCl had the quickest mean germination time (8.27). Additionally, at a concentration of 1500 ppm NaOCl, the greatest seedling vigor index (29.79) and maximum germination coefficient (12.28) were likewise obtained. With H2O treatment, the maximum shoot length (21.09 cm) was observed for seedling growth parameters. The largest root length was produced by a 10000 ppm KNO3 treatment (11.19 cm). With 20000 ppm KNO3, the maximum root dry weight was achieved (88.50 mg), whereas H2O produced the highest shoot dry weight (51.0 mg). Additionally, it was discovered that a treatment with 10000 ppm KNO3 had the best root-shoot ratio (0.72). The research thus supports the possible use of seed priming as a method to improve faba bean seed germination and seedling growth. NaOCl and KNO3 seemed to work best for faba bean seed germination and seedling growth.

Tobacco (Nicotiana tabacum L.) topping is one of the essential practice to obtain good quality and adequate yield. The suckericide (Flumetralin as a best herbicide and plant growth regulator). For the purpose to compare topping as manual and herbicide application the experiment was conducted on flue cured Virginia (FCV) tobacco at Tobacco Research Station, Khan Ghari, Mardan during 2021-2022. The experiment was conducted in RCB design with three replications and five treatments (Control, Manual de-suckering, 1000, 1200, 1500 ml of Flumetralin ha-1). Treatments were applied at three stages (button stage, early flowering stage and late flowering stage). The data revealed that topping timing and maximum dose (1500 ml ha-1) of (Flumetralin) resulted maximum (896 cm-2) leaf area, less number (14) of sucker plant-1, lower (132 g) green weight and dry weight (20.30 g) of sucker plot-1, more cured weight (5.08 kg) of leaves plot-1 and maximum yield (3038) kg ha-1, lower nicotine contents (2.26) and less sugar contents (16.24) at button stage. Moreover, Flumetralin application on at button stage resulted less sucker growth and enhanced leaf yield. I suggest that the tobacco K399 with the application of suckericide and growth regulator (Flumetralin) have the potential to incorporate in further breeding program for low content of nicotine, reduced sugar content and high yield.

2024
Yannick Karimba | Canisius Patrick Mugunga
Conversion of land use from forest to agricultural uses modifies soil quality through physiochemical soil properties changes. This study was conducted in Rwanda’s central plateau agro-ecological zone to evaluate the effect of forest and agricultural land uses on soil quality. The study was conducted in 2020. Soil samples were collected at the top, middle and bottom positions of each of the two land uses. We analyzed soil bulk density, soil moisture content, soil pH, soil organic matter (SOM), total nitrogen (TN), available phosphorus (Av P), and CEC for each position of the land uses. Data were analyzed using ANOVA in GENSTAT version 13. The results revealed that soil properties were significantly affected by land use change. Analysis of variances (LSD<0.05) results showed, however, that treatments were not significantly different within the same land use. The results showed that treatments from top position of forest lands had the highest mean values for soil organic matter and total N parameters with the respective mean values of 6.58 %, and 0.37 %. Treatments from middle position of forest lands had the highest mean values for soil moisture content and Av P parameters respectively with 23.60 % and 29.56 ppm. But, soil bulk density was high on top position of agricultural land with a mean value of 1.49 g/cm3. Land users are advised to apply crop and soil management techniques which maintain soil quality and productivity on agricultural lands.

Harun Hurma | Emir Can
Since the concept of brand has a wide and diverse range, it is divided into different groups from different perspectives. Local brands are products that are produced, manufactured, and sold by a company in a specific city or that are distributed in a constrained area. This study’s primary goal is to assess how local brands selling milk and dairy products in a particular region are perceived by local consumers. It also seeks to analyze the standing of local producers in this sector and consumer attitudes toward regionally branded goods by highlighting the significance of milk and dairy products in terms of human health. The study makes use of survey information from 381 households in Süleymanpaşa Districts of Tekirdağ-Türkiye. The data were analyzed using fundamental statistical techniques, factor analysis, and logistic regression analysis. In the survey, it was found that 85.0% of participants were familiar with the idea of local brand, while just 15.0% were not. Consumers who said they buy local brand milk and dairy products made up 78% of the sample. Consumers found local products to be more natural and tastier than national brands. According to the factor analysis, the judgements influencing customers’ preference for local brand milk and dairy products were classified into five factors. These factors are named as naturalness and quality, price and promotion, health, food safety, brand and image. Logistic regression analysis was used to explain the association between purchasing local brand milk and dairy products and factor scores, as well as knowing the notion of local brand. Those who favor “Naturalness and Quality” in purchased milk and dairy products are nearly three times more likely than those who do not to purchase local brand milk and dairy goods. With a probability of 68.4%, those who do not understand the notion of local brand will not purchase local branded products.
