Alchemilla genus, which belongs to the Rosaceae family, is a medicinal plant used for various purposes among the people. Species of this genus are known in Turkish folk medicine as lion claw or hazelnut grass. Especially, they are used mainly women’s illnesses, in gastritis, anti-inflammatory, as carminative, and in the treatment of wound. Besides the antimutagenic effect of Alchemilla alpina L., its above-ground parts are used for antimycotic purposes in the form of tea or oral care water. In this study, it has been aimed to determine the antimicrobial effect of the above-ground parts of Alchemilla alpina extracts obtained from methanol, ethanol and chloroform and the antioxidant activity of different concentrations of the extract obtained from methanol. The antimicrobial activity of methanol, ethanol and chloroform extracts of the above-ground parts of A. alpina has been determined according to disk disc diffusion method. In the results obtained have been showed that these extracts inhibited the growth of some bacteria (Staphylococcus aureus ATCC25923, Escherichia coli ATCC25322, Klebsiella pneumoniae ATCC700603, Bacillus megaterium DSM32) and yeasts (Candida albicans FMC17 and Candida glabrata ATCC66032) at different rates (8-23 mm). The antioxidant activity of different concentrations (1.25, 2.5, 5 and 10 mg/ml) of the above-ground parts of A. alpina extract obtained from methanol has been determined according to the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity method. In the results obtained, it has been observed that the effect of removing DPPH radical of A. alpina increased depending on increasing concentrations.

Yağlı tohumlu bitkiler, Türkiye’de arz açığı yüksek olan ürün gruplarından biridir. 2018 yılı verilerine göre Türkiye’nin sadece ayçiçeği ve ayçiçek yağı ithalatı için ödemiş olduğu tutar 762 milyon ABD$’dır. Aynı yılın verilerine göre Türkiye’nin yağlı tohumlar üretim miktarı yaklaşık 4 milyon ton olup, üretimden ayçiçeğinin aldığı pay ise %48,62’dir. 2018 yılında ülke yağlık ayçiçeği üretim alanı yaklaşık 650 bin ha, üretim miktarı 1,8 milyon ton ve verim değeri de 277 kg/da olarak gerçekleşmiştir. Ülke genelinde ilk beş sırada yer alan illerin toplam yağlık ayçiçeği ekim alanı ve üretim miktarındaki payı yaklaşık %70 düzeyindedir. Birim alandan elde edilen verim değerinde Konya 408 kg/da ile ilk sırayı alırken, ekim alanı en yüksek il olan Tekirdağ ilinde değer 235 kg/da düzeyindedir. Türkiye’de 1998-2018 arası dönem dikkate alındığında, yağlı tohumlar üretiminde %66,43 oranında artış sağlanmış olup, bu artışta üretim miktarı bakımından en önemli değişim %126,65 pay ile ayçiçeğinde gerçekleşmiştir. Zira, bu dönemde yağlık ayçiçeği verim değeri 146,76 kg/da’dan 277,00 kg/da düzeyine ulaşmıştır. Türkiye’nin yağlık ayçiçeği üretiminde kendine yeterlilik oranı %64,30 olup, önemli düzeyde arz açığı mevcuttur. Yağlık ayçiçeği üretiminde üretici geliri üzerinde en etkili destekleme uygulaması fark desteği uygulaması olmasına rağmen 2017-2019 döneminde ilan edilen birim fiyat değerinde bir değişiklik olmamıştır. 2018 yılında Türkiye’de yağlık ayçiçeği ortalama verim değerinin 277 kg/da olduğu dikkate alındığında fark desteği uygulamasının yağlık ayçiçeğinde üretim değerini birim alanda 110 TL/da artırmaktadır.

Environmental concerns together with social and ethical issues raise consumers’ interest in sustainable production and consumption practices. With rising trends of fair trade and high popularity of organic and local production in recent years, the demand for geographical indication registration has also increased by agricultural producers as a way of transmitting further information to raise reputation of their products. This research aims to assess the impact of geographical indications on export performance of Turkish agricultural products and foodstuffs. Findings reveal that geographical indications increase export revenues. Results communicate an important message to policy makers to promote the protection of geographical indications.

There are few studies in Botswana which have examined the relationship between agriculture and economic growth. The uniqueness of this study is grounded in investigating disintegrated agriculture components into crop production and livestock production and investigating their nexus with economic growth. This study estimated the short and long term effects between crop production, livestock production and economic growth in Botswana for the period 1990 to 2017. The Auto-Regressive Distributed Lagged (ARDL) bounds testing approach was employed to investigate the stated relationship. Study findings from the ARDL bound testing approach confirm evidence of a long-run equilibrium relationship between crop production, livestock production and economic growth. Results indicated that livestock production has a positive and significant impact on economic growth both in the short run and long run. On the other hand crop production has a positive and significant impact on economic growth only in the long run. Efforts towards supporting agricultural sector growth should be emphasized to promote agricultural sector productivity in a bid to forge a move away from dependence on imports of food in Botswana. To enhance economic growth, in both the short run and long run, the government of Botswana and all relevant stakeholders should invest in and promote livestock production. In the long term, policies that foster crop production are essential for economic growth.

Faba bean is the most important legume grown in Ethiopia. But, insect pests have been causing its substantial loss under farmers’ storages. A survey to assess the farmers’ pest protection practices of stored faba bean was conducted in its selected major growing peasant associations of the Farta District from 4 January 2019 – 15 May 2020. Semi-structured questionnaires and farmers’ participatory discussion were used to conduct the study. Accordingly, the majority of farmers (66.7%) harvested their grain in usual time (in December) fearing insect pests infestation. A substantial proportion of the farmers (25%) used a combination of cultural and botanical methods, followed by botanicals (20.83%) for grains protection. Eucalyptus globlus, Croton macrostachyus and Otostegia tomentosa were the three most commonly used botanicals and suggested to be potent. Threshing was done most commonly by livestock (66.7%), followed by beating with sticks (25%) both of which are not recommended as they might lead to grain losses. The insect infestation level was high in threshed and un-threshed forms of faba beans after 3 and 7 months storage periods, respectively. Consequently, the farmers’ traditional practices were ineffectual for storing beans for longer periods. Therefore, planning pest management strategies of stored beans are desirable.

Catalase from the thermophilic fungus Mycothermus thermophilus is a bifunctional enzyme with a secondary phenol oxidase activity (CATPO). MtCATPO catalyses the oxidation of catechol, chlorogenic acid, caffeic acid and (+)-catechin to yield mainly dimers, and higher molecular weight oligomers and polymers. The role of this phenol oxidase activity is not known. Here, the antioxidant capacities (AC) of the phenolic substrates in the absence and presence of MtCATPO were compared. The oxidized products displayed enhanced AC reaching a maximum of 2.4-fold with catechol. Other phenol oxidases (laccase and tyrosinase) did not yield AC enhancement to the same extent. MtCATPO-treatment increased AC of green and black tea infusions, as well as water extracts of samples collected from a black tea production line up to 28%. The bifunctional MtCATPO appears to be an important antioxidant enzyme with a wide range of potential applications in the food, neutraceuticals and pharmaceuticals industry.

Tandojam is one of the main tomatoes producing city in Pakistan. Several tones of tomatoes are produced in the Tandojam each year. The main objective of the study was to estimate the intensity of tomato post-harvest rot in the vicinity of Tandjam, so curative strategies can be explored. A survey was conducted in the surrounding of Tandojam viz; Tando Allahyar, Sultanabad Vegetable Market, Tandojam city, Tando Qaiser, Bahawal Zaur, and Hyderabad Vegetable Market. A total of 20 tomato growers/farmers, 30 brokers, and 23 small shopkeepers were interviewed based on the proforma developed in the current study. The fruit rot infection among all 20 different fields ranged from 5 to 65% with 31.85% infected fruits by Alternaria. At Sultanabad and Hyderabad vegetable markets infection was ranged from 20 to 60% and 10 to 70%, respectively, with mean percentages 37 and 38.5% infected by Alternaria sp. Infection in small shops was ranged from 16.67 to 60% in Tandojam city and 16.67 to 53.33% in Tando Qaiser. The overall comparison revealed 30 percent infected fruit by Alternaria under field conditions, 36 percent at the vegetable market, and 43 percent at small shops level. Controlling tomato rots is a big challenge as the intensity of this disease is unknown in different regions. This research has significantly contributed to estimating the intensity of this disease.

Stress parameter changes (cortisol, glucose, sodium and chloride) and histological alterations (gills, liver, kidney, and spleen) in Asian Catfish (Pangasius hypophthalmus) in transport were investigated. In this study, three separated trials were fulfilled. These were without tricaine, 40 and 60 mg L-1 of tricaine, respectively. Each trial consisted of 4 stages, control (C), transfer (AT), transport (TP) and recovery (24 h). After each stage, blood samples were taken and then, gills, liver, kidney, and spleen samples were collected for histological examination. In the transport without tricaine, the fish glucose increased from 50-60 mg dL-1 to 70-80 mg dL-1 and cortisol increased from 30 ng dL-1 to 90 ng dL-1 in. Sodium was 127-132 meq L-1 in the AT and TP, while 138 meq L-1 in the C and recovery. Cloride changed 103 meq L-1 in the TP, while approximately 107 meq L-1 in C, AT and recovery in the transport without tricaine. In the second trial, the fish glucose increased from 50-65 mg dL-1 to 80-90 mg dL-1 cortisol decreased from 60-70 ng dL-1 to 35-45 ng dL-1 in the transport with 40 mg L-1 of tricaine. Sodium was 130-140 meq L-1 in the C and recovery, while 125 meq L-1 in the AT and TP. Chloride was about 110 meq L-1 in the C, AT and recovery, while 102 meq L-1 in the TP in the transport with 40 mg L-1 of tricaine. In the third trial, the fish glucose was 40-55 mg dL-1 in the C, AT and TP, while 25-30 mg dL-1 in the recovery. Cortisol was 35-40 ng dL-1 in the C and AT, while 25 ng dL-1 in the TP and recovery. Sodium was 126-128 meq L-1 in the C, AT and recovery, while about 119-122 meq L-1 in the TP. Chloride was 110 meq L-1 in the C, AT and recovery, while 104-106 meq L-1 in the TP in the transport with 60 mg L-1 of tricaine. The end of the experiment, it is realized that the usage of the tricaine had positive effects on Asian catfish transport.
