Increased urbanization and industrialization in recent time has made a significant impact on air quality of the area. The atmosphere is rich in propagule of different fungal species. The investigation on airborne Aspergillus contribution was conducted in Periphery of Raipur city from February, 2018 to March, 2019 with the help of gravity petriplate containing PDA (Potato Dextrose Agar) medium. In this study, total 11 species of Aspergillus were recorded. The percentage frequency and percentage contribution of different Aspergillus species were different in different seasons. Aspergillus niger was most frequent throughout the year followed by Aspergillus fumigatus, A. flavus, and A. nidulans etc. While Aspergillus clavatus, and A. versicolor, A. aculeatus were the least frequent species. The result indicated the highest percentage contribution of Aspergillus niger (43.29 percent) followed by A. fumigatus (9.02percent), A. flavus (8.42 percent) while A. clavatus (0.21 percent). The objective of the studies was to determine a seasonal variation in concentrations of Aspergillus on the basis of meteorological parameters.

This article evaluates water quality of the river Šlapanka, which runs through a typical landscape of Českomoravská vrchovina. It deals with water quality at present and with its long-term development (since 1976). A significant part of the article consists of evaluation of pollution sources (agriculture, industry, population). The type of pollution sources is distinguished by dependence analysis of concentration of substances on flows and in different seasons. At the end of the article there are measures suggested to reduce the impact of pollution sources.

Heartwood decay is one of the major pathological constraints affecting the quality and marketable volume of tropical timber. A study on its behavior was conducted on Pericopsis elata in order to contribute to its sustainable management in Cameroon. Tree susceptibility to heartwood decay was evaluated using three diameter classes, based on allometric equations between decayed and healthy trees. Wood samples and visible macromycetes were taken from living and felled trees with an auger. Isolation of microfungi was performed on potato dextrose agar medium and their identification was based on the morphological and microscopic characteristics of the mycelium and conidia with reference to identification keys of mycology. Identification of macromycetes was based on their morphological characteristics as described in reference books on macromycetes identification. Results show that diameter class ]110, 120[ presented highly significant (P<0.05) volume loss (3755.96 cm3), followed by diameter class ]100, 110[. Microfungi frequently associated with heartwood decay of P. elata were Cercospora sp (24.57%), Fusarium oxysporum (12.64%) and Penicillium sp (12.58%) in living decay trees and Aspergillus niger (25.19%), Cercospora sp (22.21%), Penicillium sp (17.69%) and Phoma sp (15.05%) in felled decay trees. Macrofungi associated with living trees were Inonotus sp and Ganoderma sp. This is the first time that these fungal species are reported on P. elata wood. This study provides baseline information for the study of heartwood decay and management of P. elata in Cameroon.

This research was aimed to isolate and identify microbes which antagonistic against Fusarium oxysporum, the causative agent of vascular wilt in watermelon plants. The antagonistic microbes were isolated from soil samples collected from rhizosphere of watermelon farm located at west Sanur village, South Denpasar, Bali.  Isolation of fungi and bacteria were conducted on potato dextrose agar medium (PDA) and nutrient agar medium (NA), respectively.  Fungal isolates were then observed under light microscope for its morphological characteristics before identification using a reference book.  Bacterial isolates were characterized using various tests, such as gram stain reaction, existence of endospores, catalase reaction, and ability to ferment various sugars.  Their characteristics were then compared with those described in a reference book.  Two fungal species (Trichoderma harzianum and Trichoderma viride) and two bacterial antagonists (Pseudomonas sp. and Bacillus sp.) were found to have potential to be developed as biocontrol agents to inhibit the growth of F. oxysporum.

Arab Journal of Plant Protection, 39(1): 29-38. Seed-borne fungi adversely affect seed germination and seedling vigor and results in economic loss to farmers. In the present study, the antifungal activity of aqueous and alcohol extracts from eggplant (Solanum melongena L.) roots against fungi isolated from local wheat grains stored in the old Hilla silo and the new Hilla silo in Babylon, Iraq were investigated during the growing season 2017-2018 by using the poisoned food technique. The ability of the isolated fungal species for aflatoxins production was assayed. The results obtained showed that the aqueous extract contained flavonoids, whereas the alcohol extract contained flavonoids and alkaloids. Three fungal species associated with stored wheat grains were isolated, namely: Aspergillus niger, Penicillium notatum and Fusarium oxysporum. It was found that the extracts had a significant inhibitory effect on the growth of these fungi grown on potato dextrose agar medium compared with the control at P=0.05. At a concentration 36 مجلة وقاية النبات العربية، مجلد 39 ،عدد 1( 2021 ) of 10 mg/ml, the alcohol extract had a significantly higher inhibition rate which reached 91.11, 88.88 and 91.11%, on the three fungi, respectively, as compared to 86.66, 86.66 and 83.33% for the aqueous extract, respectively. The results also showed that Aspergillus niger and Penicillium notatum were able to produce aflatoxins. Keywords: Aflatoxins, alcohol extract, aqueous extract, flavonoids.

The Relationship

The article discusses a non-standard view of the formation of human capital for work in organizations of the agricultural sector of the economy, in the context of modern socio-economic transformations. In the classical sense, human capital for agriculture should be formed and developed in rural areas. But in real life, this is not always the case, because there are many factors that prevent the classical solution of this problem. First, the demographic factor affects, second, social and household factors, and third, in many rural areas there are no working agricultural organizations where qualified agricultural specialists can work. All these and other circumstances actualize the problem of the quality of human capital in rural areas in relation to the development of agricultural production.

Education Status

Digital libraries, designed to serve people and their information needs in the same way as traditional libraries, present distinct advantages over brick and mortar facilities: elimination of physical boundaries, round-the-clock access to information, multiple access points, networking abilities, and extended search functions. As a result, they should be especially well-suited for the disables. However, minorities, those affected by lower income and education status, persons living in rural areas, the physically challanged, and developing countries as a whole consistently suffer from a lack of accessibility to digital libraries. This paper evaluates the effectiveness and relevance of digital libraries currently in place and discusses what could and should be done to improve accessibility to digital libraries for under-graduate students.
