<abstract xmlns="http://www.w3.org/1999/xhtml">Sugar beet leaf spot, caused by the air-borne fungus Cercospora beticola Sacc., leads to a decrease in sugar beet leaf mass and the consequent regrowth of leaves based on exploiting the sugar reserves stored in the plant’s roots, thus ultimately resulting in lower yields and sugar contents of sugar beets. Azoxystrobin belongs to the group of QoI fungicides, which inhibit mitochondrial respiration by blocking cytochrome c reductase. The QoI fungicides are characterized by a very high risk of resistance interfering with their biological activity. For the purpose of testing the azoxystrobin sensitivity of the Cercospora beticola population found at the site of Rimski Šančevi, a collection of 84 isolates was assembled and tested for sensitivity to azoxystrobin by measuring the mycelial growth on fungicide-amended media with the addition of SHAM. The results obtained indicate that none of the isolates tested exhibited complete sensitivity to azoxystrobin, 4% were found to have reduced sensitivity, 26% were moderately resistant and 70% were highly resistant. A higher proportion of resistant isolates recorded is associated with the loss of azoxystrobin biological efficacy at the experimental site.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The beneficial effects of walnuts and walnut products on human health, due primarily to their rich polyphenolic content, have been appreciated as an empirical fact for centuries. The purpose of this study is to determine the polyphenolic contents of liqueurs made from the walnut selections ‘Rasna’ and ‘Sava’ and the walnut cultivar ‘Šampion’ (all harvested at three different times), as well as the polyphenolic contents of their green husks. The walnut liqueurs were prepared according to two traditional recipes using young walnut fruits. The highest antioxidant capacity was recorded in the liqueur made from the ‘Rasna’ walnut selection (89.94%), whereas the highest contents of phenols (83.28 mg GAE/g FW), flavonoids (0.83 mg QE/g FW) and proanthocyanidins were found in the liqueur made from the ‘Šampion’ cultivar (14.75 mg CE/g FW). The youngest ‘Rasna’ walnuts, harvested at the first experimental time point, exhibited the highest phenolic and tannin contents, whereas the highest flavonoid content was observed in the ‘Šampion’ cultivar. The biochemical results obtained indicate a decrease in the polyphenolic content of walnut fruits with their growth and development. Moreover, the polyphenolic profiles of the walnut liqueurs considered were found to be greatly affected by the method of preparation and the cultivar/selection of walnuts.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Organic agriculture has the potential to reduce the negative impacts of conventional agricultural practices and enhance rural economic development. Since research on Sri Lankan farmers’ attitude towards organic agriculture has been rare, this research aims to explore the farmers’ viewpoint on organic agriculture. Two main rural districts were purposely selected for this investigation since these districts have a high potential for organic agriculture. Two Divisional Secretariat (DS) divisions from each district and 75 farmers from the farming community of each DS division were randomly selected to form a sample of 300 farmers. Data were collected from July 2017 to April 2018 and analyzed using descriptive statistics and binary logistic regression. The results revealed that a majority of the farmers (74%) were well-aware of organic agriculture and agricultural extension programs, while training was the primary information source in both districts. As per the mean analysis, the farmers had a positive attitude towards health-related and environmental protection aspects. However, they had a negative attitude towards the complexity of organic agriculture and unavailability of a suitable market for organic products. Results of the binary logistic regression revealed that the education level of the farmers significantly affect their attitude towards organic agriculture. The availability of traditional knowledge and technology relevant to organic agriculture, favorable climatic condition, and some government support were the main potentials, while labor intensiveness was the main challenge. Thus, creating better marketing facilities for organic products, providing the required amenities for producing organic food, processing, and value addition will promote organic agriculture among more farmers, supporting sustainable development.</abstract>

Farmers’ Attitude Towards Organic Agriculture: A Case of Rural Sri Lanka

<abstract xmlns="http://www.w3.org/1999/xhtml">The study assessed adoption of rice post-harvest technologies among smallholder farmers in Osun State, Nigeria. Data were collected from 120 respondents through a structured interview schedule using a multistage sampling procedure. Percentages, means, Chi-square and correlation were used to analyse the data and draw inferences. The results show that about 52.5% of the respondents had favourable perception, while 47.5% had unfavourable perception towards adoption of the rice post-harvest technologies. Rice milling (mean=4.54) and harvesting matured panicles at the right time (mean=4.47) ranked highest among the adopted post-harvest technologies, while majority (65%) of the respondents adopted the rice post-harvest technologies at moderate level and 35% had high level of adoption. Inadequate capital (mean=1.75) and poor extension contacts (mean=1.67) were the major constraints associated with the adoption. Also, there was significant association between sex (χ2= 38.174), marital status (χ2=32.85) and adoption of the rice post-harvest technologies, while age (r=-0.531), household size (r=0.414) and the quantity of rice produced (r=0.345) had significant relationship with adoption of the post-harvest rice technologies. There was moderate level of adoption among the farmers. Financial institutions, governments and non-governmental organisations should provide functional credit facilities and government should employ more extension agents to promote adoption of high-quality enhancing post-harvest technologies for sustainable rice production in Nigeria.</abstract>
