2022
Kanij Fatema Tuz Zohora | Md. Riyadh Arefin
Tea is the most consumed drink after water as well as is one of the prevalent and the cheapest beverage which consumed globally. Tea is considered a healthy beverage due to the presence of several antioxidants and minerals such as potassium, magnesium, calcium & manganese. Different kinds of teas are manufactured in different countries based on taste, habit and culture of the people. Normally, tea can be categorized into three groups: green tea (unfermented), Oolong tea (partially fermented) and black tea (fully fermented) based on tea processing. Tea is a rich source of polyphenols and now-a-days interest in the possible health benefits of polyphenols, particularly flavonoids, has increased owing to their antioxidant and free-radical scavenging abilities. The rising demand of tea is considered one of the significant components for the worldwide beverage market growth. Tea industry makes a vital contribution to the economy of the respective tea producing countries like China, Japan, India, Sri Lanka, Bangladesh, Kenya etc. At the present time with the rising demand of tea it is needed to emphasize for exploring alternative means of increasing profits from tea cultivation. The tea market price is low in Different countries like Srilanka, India, Bangladesh, Kenya etc. comprises with high cost of production. For this reason, there is no alternatives rather than product diversification of tea through value addition which can be an important approach to mitigate the impacts of low market price and high production costs. This review broadly focuses on the issues leading to the development of wide range of tea and tea product diversification. This paper is also associated health benefits with different types of tea, nutraceutical beverage, confectionary items, toiletries and cosmeceuticals which being commercialized in different parts of the world which are gaining consumer acceptance and also face the challenges of global marketing by tea industries that’s are described in this paper.

Cutting reproduction is the cheapest and most practical method for plants capable of clonal regeneration. However, the difficulties in adventitious root formation in black mulberry cuttings create a disadvantage for mulberry growers. This study aimed to investigate the effect of IBA and Paclobutrazol applications on the rooting ability of black mulberry hardwood cuttings. The experiment was carried out in the polyethylene greenhouse of Tokat Gaziosmanpaşa University Agricultural Research and Application Center in February 2022. As a material, hardwood cuttings prepared from one-year-old branches of breeding black mulberry trees within the body of the directorate were used. The study was set up in a randomized plot design with 3 replications and 15 cuttings in each replication. In the study, pure water as a control group, 6000 ppm IBA and doses of 1000 ppm, 2000 ppm and 3000 ppm Paclobutrazol respectively were applied to black mulberry wood cuttings separately and together. After the application, the cuttings were planted in perlite medium. The cuttings were kept in the rooting medium for 90 days and then removed; rooting rate, root number, root length and root diameter values were recorded. As a result of the study, the effect of the applications on the root number of the cuttings was not observed while the rooting rate, root length and root diameter parameters were observed. In terms of rooting rate, the best result was obtained from IBA+PBZ 1000 application (40.00%) compared to the control group (0.0%). The highest root length was determined in IBA 6000 application, and the thickest root diameter values were determined in PBZ 1000 application.

Özlem Kızılırmak Esmer | Erinç Koçak | Alp Efe Cevrem | Orhan Kıcıkoğlu
With the increasing world population, the food need of humanity is increasing proportionally. Agricultural wastes constitute an important potential for the global economy as they contain components that are less preferred to be consumed as food due to their low bioavailability due to their indigestion in the human body or due to their sensory properties, but that may be beneficial to human health such as antioxidant substances and antimicrobial agents. The benefits of using these wastes in terms of economy and reducing environmental pollution are obvious. Tomato, which is one of the most used agricultural products in our country and the world, is processed by removing its skins in the processing of many products. Tomato skins cause serious environmental problems and economic losses unless they are valorized. In this regard, this study aims to optimize the extraction efficiency, the antioxidant capacity, and total phenolic content of the tomato peel extract according to the independent variables of temperature and time, while the alkaline extraction process applied to tomato skins is cheap and industrially applicable. Using response surface methodology, the highest extraction yield (28.77 g/100 g dry extract), total phenolic content (3819.32 mg GAE/100 g dry extract), and total antioxidant capacity (2737.82 µmoL Trolox/100 g dry extract) were obtained under extraction conditions at 100°C for 5.26 h. According to LC-MS/MS results, tomato skins treated with alkali contain various phenolic acids and some flavonoids. The phenolic component found in the highest amount in the tomato peel extract was determined as p-coumaric acid (429.99 ± 38.53 mg/100 g dry extract). Other important phenolic components are ferulic acid (12.44 ± 2.06); 4-hydroxy benzoic acid (7.13 ± 1.01) and vanillin (2.47 ± 0.22) mg/100 g dry extract.

In the agronomical field, different internal and external factors are responsible for substantially diminished crop harvest. A hindrance that can be listed in those factors is insect pests. African bollworm (Helicoverpa armigera) is a significant polyphagous, rapacious feeder, and the serious pest of agricultural cosmos. This pest can infest a wide array of species (almost 180 plant species) and a diverse range of families regarding it to be the most versatile and economically important nuisances for crops. H. armigera is widely far-reaching throughout the globe mostly in the Asian domain. Likewise, the subsequent number of instars makes it more detrimental and positively influences its existence pattern. The biological parameters like high fecundity, reproducibility, and comparatively long-life period support in the incitement of damage threshold (DT). Thusly, this article depicts the presentation and control tactics against H. armigera, and further incorporates science and damage to acquaint this pest and access raise in production.

Mustafa Ulaş
Events such as oxidative stress caused by spinal cord injury (SCI) are a serious condition because they negatively affect many organs. Alternative treatment options for this type of injury are quite limited. In this study, we planned to investigate the effect of oxidative damage on the spleen tissue of rats with spinal cord damage and the protective role of valproic acid (VPA) in this damage. Sixteen Wistar albino rats were divided into two equal groups. No treatment was administered to the rats in Group 1 (SCI-(Control), but a single dose of 300 mg/kg intraperitoneally VPA was administered to the rats in Group 2 (SCI-VPA). Superoxide dismutase (SOD) activities, total antioxidant status (TAS) and total oxidant status (TOS) levels were examined as markers of oxidative stress in spleen tissues taken after decapitation of rats. VPA treatment increased the SOD and TAS level but decreased the TOS level, indicating improved oxidative damage and impaired enzymatic antioxidant levels in spleen tissue homogenate damaged by SCI. We have observed that VPA, which has many beneficial properties, has a significant healing effect on spleen tissue affected by SCI-induced oxidative stress.

The study was conducted to investigate the effects of ensiled guinea grass (GG)- cassava peel (CSP) enriched with soybean cheese waste (SBCW) in varying proportions into 4 treatments: T1 (GG100%), T2 (GG80% + CSP10% + SBCW10%), T3 (GG60% + CSP30% + SBCW10%) and T4 (GG40% + CSP50% + SBCW10%) on West African Dwarf goats. Twenty WAd goats were allocated into four silages of five growing WAd goats each. Daily feed intake and weekly weight gain were measured for twelve weeks of the experiment. Digestibility study was carried out using Three animals per treatment for faeces and urine collection. Blood samples were collected via jugular vein for blood profile analysis using standard measures in a completely randomized design. The Crude protein (CP) concentrations of silage increased with the increasing level of cassava peels. Crude fiber levels of the silages also followed the same trend. The group of animals fed T4 had highest feed intake among the treatment groups. Daily weight gain of goats in T4 was better enhanced than other treatments. The apparent digestibility was significantly different (P˂0.05) among the treatment groups. There were diet effects on the parameters measured for rumen liquor of the animals fed silages. The treatments had no effects on the haematology and total protein of goats fed diets. It is therefore indicated that agro-industrial by-products ensiled with guinea grass are potential means of feed sustainability during the dry season period for goats in Nigeria without any deleterious effects on goats’ health and performance.

Wheat, which is one of the most widely cultivated crops in the world, has great importance in terms of economy. Wheat is one of the basic food sources of human beings, is one of the first cultivated plants. In order to meet the nutritional needs in parallel with the increasing human population, agricultural production needs to be increased. Fertilization is the most important factor in increasing the yield. Innovations in fertilizer technology and improvement of use efficiency are of great importance. In this study, different doses of mineral (0, 15, 20, 40 kg/da DAP and 0, 20, 30, 40 kg/da AS) and organomineral fertilizers (0, 15, 20, 40 kg/da 20: 20: 0 and 0, 20, 30, 40 kg/da 25: 0: 0) were applied with or without microbial encapsulation to wheat (Triticum aestivum L.) plants (Rumeli cv.) in pots. Some of macro and micro plant nutrients were analysed in three different harvest periods from seed sowing to compare the fertility of the applied fertilizers. According to the results of the research, all applications showed significant differences in terms of all examined parameters. Organomineral fertilizers were found to be more effective than mineral fertilizers. It has been observed that microbial encapsulation is effective at varying levels according to changing fertilizer type and dosage.
