Özdal Köksal | Duygu Aktürk | Sema Gün
Ever-developing agricultural technologies and progress in communication science increase competition and globalization in converge countries. Agricultural fairs offer ambient to bring producers and input-suppliers of agriculture together at certain places and times. They offer direct and efficient information about new technologies to producers. German Agricultural Society and Leader Farmer Association have jointly organized outdoor fairs in Turkey since 2010. Agriculture Days Fair is one of the most important events among these jointly organized fairs. This study was conducted to determine the reasons for producers’ participation in these fairs held in 2015 and 2017 and to determine the effects of socio-economic characteristics of the producers on their reasons for participation in these fairs. A total of 589 questionnaires were made in this study (250 in May 2015 fair and 339 in August 2017 fair). The same questionnaire forms were used in both years. CHAID analysis technique was employed in analyzing data gathered from the producers. It was observed that producers generally participated in agricultural fairs just for the excursion or spent time with their families at weekends. However, it was also determined that the producers were informed about the agricultural fairs by producer organizations and Leader Farmer Association participated in the fairs to promote a new products or to give information about new technologies and inputs. It can be suggested that beyond informing producers about the fairs, Leader Farmer Association formed within the scope of Leader Farmer Project initiated with the support of German Agricultural Society (DLG) should convey information about how important the fairs are in the acquaintance with introducing new information and technologies.

Potato (Solanum tuberosum L.) is one of the most significant vegetable crops for humans along with corn, wheat, and rice. In this study, quantitative analysis of phenolic compounds was carried out for 21 promising potato clones and three commercial cultivars. LC–MS/MS was used for the chemical analyses. The TOGU 3/518 clone had the highest level of 4-hydroxybenzoic acid as 138.51 ± 7.35 µg/kg. TOGU 12/29 and TOGU 2/198 clones, on the other hand, had 126.24 ± 2.29 and 125.29 ± 2.74 µg/kg of 4-hydroxybenzoic acid, respectively. Salicylic acid which is a pharmaceutically significant compound was found in TOGU 3/518 clone (125.66 ± 11.51 µg/kg) as a major product. This compound was also found in TOGU 2/198 (111.27 ±1.31 µg/kg) and TOGU 12/29 clones (111.07 ± 3.68 µg/kg) as the third and fourth most abundant. In terms of caffeic acid, TOGU 3/110 clone contained the highest level (42.50 ± 3.73 µg/kg). While TOGU 7/146 clone included the most protocatechuic acid (53.98 ± 1.47 µg/kg), TOGU 3/480 clone consisted of most gentisic acid (30.79 ± 0.51 µg/kg). Quercetin, an important flavonoid found many aromatic and medicinal plants, was highest in TOGU 12/29 clone (6.27 ± 0.15 µg/kg).

The aquaculture industry in the Middle East (ME) is still relatively new compared to other parts of the world, making this region highly dependent on other countries for the production of food and feed needs. Aquaculture activities in the world at current is mainly focused in China; this may be propelled by its own internal demand for seafood as determined by the United Nations Food and Agriculture Organization (FAO). Challenges faced in the ME has not been elucidated so far and the issues arising might be unique only to this region due to aquaculture being in the initial stages coupled with water access and limitations, climate and geography, in addition to pollution. This review paper will present and discuss global needs for seafood focusing later on the needs in the ME, followed by a discourse into the importance, types and challenges of aquaculture in the ME. Baseline knowledge and infrastructure to enhance knowledge is a pressing need at this stage of infancy. It is hope this sector will continue to develop, and with the support of stakeholders, aquaculture in the ME will achieve a state of independence.

According to the trend of a healthy eating awareness trend, having a potential benefit on human health, some polyphenols like flavonoids, resveratrol, hydroxy-stilbenes, and phenolic acids are in the spotlight. Grapes, and one of the most widespread grape product wine; are among the best sources of these polyphenols. In this study, a highly specific, susceptible, and easy chromatographic method was brought out and validated to determine 18 polyphenols in grape and red wines. For this aim, an HPLC-PDA was used, and the separation was accomplished on an RP-ODS4 column. The method comprised of a mobile gradient phase consisting of A solution (acetic acid in water, pH 2.00) and a mixture of the solution A – acetonitrile (20:80, v/v), at a flow rate of 1.0 ml/min, and PDA detection was carried out at 260,280, 320, and 360 nm. According to the results, it can be said that the program indicated good linearity over the range of 1-40 mg L−1 of phenolics with r2>0.99. The recovery of the 18 phenolics ranges from 83.17% to 119.88% at red wines and 88.20% to 117.83% at grape juices. The method is well precise, with the relative standard deviation (RSD) of the average concentration of the phenolic compounds are ranges from 1.22% to 2.02% at red wines and 1.01% to 2.56% at grape juices.

Food security is one of the major global challenges of the twenty-first century. World population is expected to increase by one-third, between 2009 and 2050, and in Asia, crop yield is estimated to decline by 5 to 30% from 2050 onwards compared to 1990. It is high time to seek alternatives that can increase production utilizing existing resources ensuring food security. A home garden can be a viable and sustainable alternative in this regard; nevertheless, it is often neglected. Thus, this study aims to understand the role of the home garden in maintaining household food security and enhancing rural women’s status in Nepal. Two villages of Bishnupur rural municipality, namely, Bajitpur and Musharniya were selected as study sites. 78.6% of households in Bajitpur and 68.4% households in Musharniya were found to have a home garden where crops and livestock were organized in an integrated way. The home garden was found to maintain household food security, ensure food availability for most of the seasons, access of household members to food, its utilization, and stability in production. Furthermore, 66.67% and 58.33% of women sold surplus home garden products in Bajitpur and Musharniya respectively. This signifies the role of home gardening activities in uplifting the social and economic status and, farming knowledge of rural women in both villages. However, there is a lack of extension facilities and subsidies for the home garden to encourage farmers. Therefore, different models of home gardens should be developed and disseminated, prioritizing the integration of the scientific farming system with traditional knowledge for sustainable adoption of the home garden in Nepal.

In recent years, medicinal and aromatic herbs, which contain variety of antimicrobial compounds and have no risk to human health in terms of antibiotic resistance, are increasingly used as alternatives to antibiotics. In the study, chemical composition, total phenolic content, antioxidant and antimicrobial activity of essential oil and extract of Mentha x piperita L. growing wild in Eskisehir were investigated. Carvone (55.8%), limonene (12.8%), 1.8-cineole (8.7%) and trans-dihydrocarvone (6.4%) were determined as the main constituents of the essential oil, while the major components of the extract were carvone (56.4%), 1.8-cineole (14.1%) and trans-dihydrocarvone (8.4%). The total phenolic contents of essential oil (2204.33 µg GAE/g) were significantly higher than of extract (744 µg GAE/g). The essential oil and the extract were inhibited 84.08% and 42.59% by the DPPH radical, 91.87% and 48.40% by the ABTS radical, respectively. The highest inhibition zone was observed against S. aureus (23 mm). However, minimum inhibition concentration (MIC) values of the essential oil were ranged between 2.5% and 10% (v/v), while MIC values of the extract were determined as 10% and >10% (v/v). The present study demonstrated that M. piperita could be used in pharmaceutical and food applications as a natural antioxidant and antimicrobial substance.

This paper attempts to review the major sorghum production constraints, the progress and perspective on sorghum anthracnose (Colletotrichum sublineolum) resistance breeding. The importance of anthracnose in sorghum production and breeding for resistance status and progress were also primly discovered. Sorghum is an ancient environment resilient crop and believed to be a future crop due to its important merits like tolerant to stresses, wide adaptability and low input requirement. Insects and disease are major biotic impediments to realizing the yield potential of the crop. Anthracnose disease caused by Colletotrichum sublineolum is the most important disease that severely affecting the crop in all sorghum producing regions of the world. Research results revealed that anthracnose resulted in 30-50% or greater yield losses. Several management strategies such as, cultural, chemical and using resistance varieties have been developed. Employing host-plant resistance is the most economical and environmentally friendly approach which can successfully control the disease. Breeding assisted with molecular markers plays a great role in resistance breeding programme as it makes easy to screen large number of genotypes at once. Recent advancement of molecular breeding and bio-informatics tools are playing a significant role in efficiencies and precisions of resistance breeding. QTLs or genomic area for resistance were identified using traditional molecular markers and recent research results revealed discoveries of specific gene and locus using high throughput markers like SNPs using GWAS approach. The discovery of genes/QTL associated with the resistance trait, using the high through put molecular markers like SNPs, facilitates the easiest way for gene pyramiding from different individual genotypes to a single variety, introgression into adapted elite cultivar through marker assisted and editing genes for elite landraces to develop durable resistance varieties. Transgenic approach is now a day becoming a powerful tool to utilize novel alien genes for crop improvement including anthracnose resistance breeding in sorghum.

This study was conducted on a total of 776 goats (part of Central highland goat breeds of Ethiopia), 306 from Boset district of Oromia region and 470 were from Minjar Shenkora district of Amhara region. A format developed by using food and agriculture organization discerption list was used for recording of morphological traits, bodyweight and linear body measurements. Both qualitative and quantitative traits were recorded from randomly sampled mature goats and the data were analyzed using SAS software. The goat type in the study area was characterized by a higher proportion of plain coat color patterns (62.5). Ingeneral, the majority (98.4%) of the studied goats were horned and characterized by backward orientation (67%) with a straight shape (49.3%). They presented a concave facial profile (73.8%), slop up toward the rump back profile (66.2%), no wattle (99.6%), no toggle (90.7%), no ruff (85.9%) and no beard (57.3%). The location had a significant effect on body weight and some other linear body measurements. Traits like body length, rump length, horn length, head length, head width and shin circumference were significantly higher in Boset district. In contrast, rump width and cannon bone length were significantly lower. The mean body weight of male goats in Boset and Minjar Shenkora district were 30.5±1.05 kg with a range of 16 to 47 and 27.5±0.56 with a range of 13 to 57, respectively. While for female counterpart mean body weights (kg) were 28.4±0.35 with a range of 17 to 45 for Boset and 27.5±0.33 with a range 15 to 57 for Minjar Shenkora district. Heart girth had the highest correlation with body weight in both sexes and shoulder width in Boset male goats. The wider variation in most quantitative measurement traits would open an opportunity for further improvement, conservation and utilization work.

‘Circular economy’ in agriculture centres on the production of agricultural commodities using a minimal amount of external inputs, closing nutrient loops and reducing negative discharges to the environment (in the form of wastes and emissions). This can be achieved through the (re)design of maintenance, repair, reuse, remanufacturing, refurbishing, and recycling. Under the principles of CE, products and materials approaching their end-of-life stage can be regenerated or restored or replaced. Circular agriculture is aimed at closing the loop of materials and substances, and reducing both resource use and discharges into the environment. New measures like environmental taxes, insurance for liability resulting from environmental damage, cap and trade system and environmental labelling can be explored to promote transition of a current linear model to a circular one. The circular economy in Nepal is in infant stage and there is plenty of works to be done in this sector. The results of the paper will be instrumental for the transition of Nepalese agricultural sector to a more circular one.
