Ala Asi Mohammed Al-Salihi | Mehmetcan Olgaç | Emircan Dinçer | Hakan Polatcı | Onur Saraçoğlu
In Turkey, three species of mulberries, white (M. Alba), black (M. Nigra), and red-purple (M. Rubra) are grown commonly. These widely can be consumed fresh as well as dry. However, its rapid post-harvest decay raises major concerns about the sustainability of the fruit for both food and economic purposes. In this regard, besides the fresh consumption of black mulberry fruit, it can consume as dried it also offers an alternative way. In this study, it was aimed to compare some quality parameters in fresh and dry samples of Morus rubra fruits grown in Tokat. It was applied different temperatures to Morus rubra fruits that at collected in two different maturity levels (semi-ripe and full-ripe). In the drying process, mulberry fruits were dried in a hot air dryer at 40, 50, 60, and 70°C. Total phenol, Total phenol, total monomeric anthocyanin, total antioxidant capacity, colour values (L, a, b) chroma, hue (ho), and browning indices values will be measured in fresh and dried products. In addition, different mathematical models will be tried by constantly noting the weight drops of the products at certain time intervals and determining which mathematical model will best predict the drying kinetics

Belma Doğan Öz | Gamze Saner
The aim of this study is to determine the indicators used to determine the sustainability levels of nut farms and to establish a set of indicators that can be used to measure the level of sustainability of pistachio farms, based on the literature review. As a result of the literature review, among the indicators commonly used to measure agricultural sustainability, a total of thirty sub-criteria were identified, including fifteen sub-criteria for the economic aspect (farm size, yield, etc.), six sub-criteria for the environmental aspect (pesticide, fertilizer, water, energy usage, etc.) and nine sub-criteria for the social aspect (farmer’s age, education, etc.) which can be used in evaluating the sustainability of pistachio cultivation. According to this study's findings, although the theoretical principles, dimensions, and goals of agricultural sustainability are globally adaptable, the applicability of the indicators may vary between regions and countries due to geographic, climatic, and socio-cultural differences. Therefore, the sustainability assessment process requires special attention. Sufficient knowledge and expertise are required in setting goals, selecting indicators, and verifying indicators.

Ageratum conyzoides is a widely spread weed, especially in the tropical and subtropical regions. It has been reported to be used as folk medicine in different countries for treating burns, wounds, skin disorders, headaches, fever, pneumonia, gynecological diseases, leprosy, snakebites, rheumatism, inflammations, stomach ailments like parasites, colic, diarrhea, dysentery, used as a painkiller during childbirth, and many more. It has been reported to contain active secondary metabolites such as alkaloids, tannins, phenols, saponins, coumarins, essential oils, and flavonoids, which support its medicinal uses in disease treatment and prevention. It can be a potential source of drugs for various diseases. In fact, pharmaceutical companies are being run in Brazil using A. conyzoides as raw material with recommendations from the Brazilian Drug Centre. It is also used for agricultural purposes as manure, insecticide, pesticide, herbicide, nematicide, fodder, etc. In China, it is widely intercropped in the citrus orchard to control pests and weeds. The review attempts to bring together medicinal and agricultural usage of Ageratum conyzoides with scientific evidence to demonstrate its efficacy. This weed has a negative influence in agriculture and the ecosystem but after studying about its potential medical and agricultural uses, we now have a different viewpoint on this weed, and we believe that further harnessing it for such positive uses might be a management strategy for this weed.

The chemical composition of propolis from Aegean Uşak (Balcıdamı and Kaşbelen), Afyon ( Emirdağ and Dinar), Manisa (Salihli and Kula), Denizli (Merkez and Çivril), Muğla (Milas and Merkez), İzmir (Kemalpaşa and Menemen), Aydın (Söke and Kuşadası) and Kütahya (Hisarcık and Tavşanlı) was studied in order to determine the major compounds by using GC-MS. In this study, 8 % ethanol extract of propolis prepared by mixing 920 ml of 70 % ethanol and 80 g of propolis was used. Chemical analysis of propolis extracts indicated that the propolis samples had high concentrations of the aromatic acids, esters and other derivatives which are responsible for the antibacterial, antifungal, antiviral, anti-inflammatory and anti-cancer properties of propolis such as benzyl cinnamate, methyl cinnamate, caffeic acid, cinnamyl cinnamate and cinnamoylglcine besides the most common compounds as fatty acid, terpenoids, esters, alcohols hydrocarbons and aromatic acids. Also, in this research the antifungal effects of 7 concentrations (6.25, 12.5, 25, 50 ppm) of propolis ethanol extract (PEE) against Fusarium oxysporum was investigated in vitro conditions. Propolis was mixed alone or in combination with potato dextrose agar (PDA) medium at various concentrations. The results indicated that the mycelial growth of the tested fungi decreased with each increase in PEE concentrations. Propolis extract collected from Muğla province showed 77.81% antifungal effect against Fusarium oxysporum at the highest concentration (50 ppm). The lowest antifungal effect (64.52%) against the pathogen was detected in the propolis extract collected from Denizli province.

Proper scheduling gave water to the crop at the right time in the right quantity to optimize production and minimize adverse environmental impact. Therefore, the objective of this study is to quantify the effects of irrigation regimes on yield and yield components of Maize in the Lake Tana basin during 2016-2018. CROPWAT 8.0 model was used to determine the crop water requirement. Almost all parameters were adopted the default value of CROPWAT 8.0. Field data including; field capacity (FC), permanent wilting point (PWP), initial soil moisture depletion (%), available water holding capacity (mm/meter), infiltration rates (mm/day), and local climate data were determined in the study area. The treatments were arranged in factorial combinations with five irrigation depths (50, 75, 100, 125 and 150% of ETc) and two irrigation intervals (14 and 21 days) laid out in a randomized complete block design with three replications. The result was analyzed using SAS 9 software and significant treatment means separated using least significant difference at 5%. The result showed that the interaction of irrigation depth and irrigation frequency has no significant effect on the average grain yield and water use efficiency of maize. At koga, the highest grain yield (7.3 t ha-1) and water use efficiency (0.9 kg m-3) obtained from 100% ETc. while, at Ribb the highest grain yield (10.97 t ha-1) and water use efficiency (1.9 kg m-3) obtained from 21 days irrigation interval. Therefore, for Koga and similar agro ecologies maize can irrigated with 562 mm net irrigation depth and 21-day irrigation interval and at Rib and similar agro ecologies maize can irrigated with 446.8 mm net irrigation depth and 21- days irrigation interval.

The effects of drugs used in cancer treatment are not only specific to cancer cells but also negatively affect healthy cells. This study, it was aimed to investigate the protective effects of silymarin (SLY), which stands out with its antioxidant effects, against the possible harmful effects of paclitaxel (PAX), an anticancer drug, on kidney tissue. A total of 28 Sprague-Dawley female rats were randomly selected into four groups (n=7): Control, PAX, SLY, and PAX + SLY. PAX was administered 2 mg/kg to the PAX group by intraperitoneally (i.p.); SLY was administered 100 mg/kg to the SLY group by oral gavage. Also, The PAX + SLY group was administered the same dose and route of PAX and SLY as the previous groups. In the biochemical analyzes performed in blood and kidney tissues taken from animals at the end of the experimental procedures, it was determined that PAX increased oxidative stress in kidney tissue and creatinine (Cr) and blood urea nitrogen (BUN) levels in serum. In the histopathological examinations of the kidney tissue, it was observed that PAX caused pathological changes such as renal corpuscle atrophy, damage to the brush border, vacuolar degeneration, and desquamation. The administration of SLY, a pharmacological agent with anti-inflammatory, anti-apoptotic, and antioxidant effects, largely prevented these pathological changes that occurred as a result of PAX use. The results obtained in the current study showed that SLY can be used as a protective agent against harmful effects on kidney tissue in treatments with PAX.

The objective of this study was to investigate the effect of 10 mM silicon (Si) application on salt stress (50, 100, and 200 mM NaCl) tolerance in Hungarian vetch seedlings (Ege Beyazi-79) based on growth parameters (shoot length and fresh weight, organic dry matter, and moisture), bioactive compounds as chlorophyll, carotenoid, proline, protein, nitrate, and nutrient status. Silicon was applied to the seedlings from the leaves and NaCl from the salt soil, both of which were dissolved in Hoagland solution. The results revealed that the highest shoot length Si+100 mM NaCl was recorded and the highest fresh and dry weight was recorded with length Si+50 mM NaCl. The highest dry matter was obtained from Si and 200 mM NaCl. The highest chlorophyll, carotenoid, proline, protein, and nitrate were obtained from 100 mM NaCl+Si, while the lowest chlorophyll, carotenoid, and nitrate were obtained from 200 mm NaCl and the lowest proline and protein from 100 mM NaCl, respectively. The amount of K, Mg, and S were low in NaCl doses but high in Si and Si + NaCl doses, and P was higher in all groups compared to the control. The content of Na, Co, and Se were high in all groups except Cl 50 NaCl, while Mn, Zn, and Ni were higher in Si and Si + NaCl doses. Silicon content of samples was high at higher NaCl + Si doses. The results provided by this investigating indicated that silicate concentrations positively affected the parameters examined in Hungarian seedlings, and increased the tolerance of seedlings to salt stress.
