The experiment consisted of three planting materials (mother rhizomes, finger rhizomes, and mixed rhizomes) and five pre-planting storage methods (cemented floor, under tree shade, raised mesh-wired bed, pit with grass cover, and pit with soil cover). These factors were factorially arranged using a randomized complete block design with three replications. The results from the analysis of variance revealed that the seed quality, growth, and seed rhizome yield of turmeric were significantly (p<0.05) influenced by the main effect of both planting material and storage method. However, their interaction did not significantly affect these attributes (p>0.05). The highest clean and sprouted seed rhizomes, as well as total sprouts, were recorded in mother seed rhizomes and seed rhizomes stored under tree shade. Conversely, storing mother seed rhizomes on cemented floors resulted in the highest seed weight losses. Finger seed rhizomes stored in soil-covered pits produced the highest percentages of non-sprouted and decayed seed rhizomes. Regarding growth attributes, mother seed rhizomes led to the highest plant stands, plant height, stem girth, leaf growth, and tiller number. Storing seed rhizomes under tree shade performed the best across these growth attributes. Turmeric plants grown from mother seed rhizomes yielded a higher number of mother and finger rhizomes per plant and the highest fresh rhizome yield. Likewise, storing seed rhizomes under tree shade resulted in the highest fresh rhizome yield. In general, utilizing mother seed rhizomes and storing them under tree shade improved turmeric seed quality, growth, and seed rhizome yield. Therefore, farmers in the area are recommended to adopt these practices, but further research is needed to assess their economic feasibility.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"51 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140266701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines the multifaceted importance of these species, highlighting their central role in understanding cereal crop relatives and delving into their adaptability to a range of abiotic stresses, particularly in the context of climate change mitigation. Given the increasing threat of unpredictable weather patterns and global food security, the genetic reservoir and adaptability of Brachypodium species offer promising opportunities for sustainable agricultural innovation. Moreover, it is emphasized that maintaining their genetic diversity is critical, not only for continuity of research, but also for the potential ecological and economic benefits they offer. As we move through the complexities of the Anthropocene, Brachypodium is a testament to the complex interplay of genetics, environment, and human endeavor, and calls for a collaborative approach to harness its full potential for future agricultural resilience and sustainability.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"60 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140427717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, the olive pomace, by-products, was fractionated successively using organic solvents of increasing polarity (cyclohexane (CYHA), ethanol (EtOH) and distilled water) to determine their biochemical composition (total phenolic content, total flavonoid content, HPLC, and GC-MS) and biological activities (antioxidant and antibacterial activities). In addition, the olive pomace was extract directly by the distilled water to determine its physicochemical characteristics (pH, humidity and quantity of oil). The study proved that olive pomace has a low content of total phenolic content in the three extracts (from 0.81 to 2.24 mg GAE/g dry residue). Likewise, for the content of total flavonoids, it presents in the CYHA and EtOH extracts of 0.5 and 0.4 mg QE/g dry residue, respectively. GC-MS data showed the detection of 6 volatile compounds in the cyclohexane extract which contains two major compounds were hexadecanoic acid (2.23%) and 9-octadecenoic acid (8.67%). Moreover, HPLC data showed that chrysin compound was the major one among the four detected ones in the organic extracts of olive pomace. The results showed that the CYHA extract exhibited the best antioxidant power exceeds 50% on the other hand, it is less than 25% for the ethanoic and aqueous extract. In the aqueous extract there is a stronger antibacterial activity against the strain L. monocytogenes (13 mm) than the reference (ampicillin) and the bacterial strain B. cereus (11 mm) associated with their phenolic activity.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"13 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140436380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some questions were also about the types of pesticides traded in the Libyan market, their physical condition, their specialties, their commercial sources, and how to dispose of their empty containers. It became clear from this study that approximately half of the pesticide shops were in the main streets of Tripoli, and only 27% of them were in rural areas. Moreover, no less than 50% of the stores do not have warehouses, and those that do have warehouses are considered inappropriate for storing these dangerous materials. It was also shown that there is a lack of attention and implementation of the sanitary conditions in pesticide stores, including ventilation, air conditioners, and the height of the stores. We also noticed that the percentage of licensed shops designated for selling pesticides did not exceed 35%, and that many of them hold licenses not designated for selling pesticides, and some of them don’t have license. As for the materials that are marketed alongside pesticides, most of them are agricultural equipment, with the presence of fertilizers and seeds. Regarding the persons that are selling pesticides, their ages range from the twenties to the fifties, and their educational levels vary, as the percentage of illiterate people was 15%, the percentage of those who obtained compulsory primary, middle, and secondary education was 49%, the percentage of those who obtained an intermediate and higher diploma was 23%, and the percentage of university salespeople was 13%. It is striking that 79% of the sellers are not specialized in the agricultural field. As for the level of knowledge of the sellers about the dangers of chemical pesticides, it was found that 72% of them have little to moderate knowledge. In addition, 77% of them do not wear protective clothing, and only sometimes at best, which shows that 43% of the workers’ health was negatively affected by their handling of pesticides. Finally, this study showed that the pesticides circulating in the Tripoli area are liquid, solid and gaseous in approximately equal proportions. As for the specialties of pesticides on offer, it turned out that 22% of them are insecticides, 21% are herbicides, 21% are fungicides, 19% are rodenticides, and 17% are acaricides.

These effects are multiple and vary from one region to another around the world including rising temperatures, altered precipitation patterns and degradation of the natural flora. The Zarat region (Gulf of Gabes) is notable for its climate variation, shallow waters, high levels of temperature and salinity. Understanding the vegetation dynamics in this coastal protected region under climate change scenarios is important for projection to the whole ecosystems. The Maxent model is used to predict the potential distribution of plant groups and Soil Adjusted Vegetation Index (SAVI) classes for many future time-periods (2021-2040, 2041-2060, 2061-2080 and 2081-2100) under different climate change scenarios in the Zarat region.

A cet effet, une expérimentation a été menée dans une parcelle expérimentale située dans la région de Médenine, Tunisie. La culture du piment variété Baklouti a été transplanté sur un sol sableux et irriguée au goutte à goutte avec des eaux ayant une salinité de 7,3 dS/m. Trois traitements d’irrigation ont considérés. Deux traitements magnétiques consistent à traiter l’eau salée par un champ magnétique en utilisant deux magnétiseurs Delta-Water (DW) et Magiko. Dans le troisième traitement (Témoin), l’eau n’a pas été traitée. Les mesures effectuées ont porté sur l’humidité et la salinité du sol, l’indice foliaire (LAI), le poids frais, et la teneur relative en eau durant le cycle de développement de la culture. A la récolte, le rendement et ses composantes (nombre des fruits /plante, poids de fruits/plante) ont été évalués. Les résultats montrent que le pilotage d’irrigation adapté aux conditions réelles maintient l’humidité du sol proche à la capacité au champ pour les trois traitements. Par ailleurs, le pilotage adopté et les quantités des pluies reçues ont permis de réduire la salinité du sol. Les traitements magnétiques améliorent la croissance de la culture avec l’augmentation de l’indice foliaire. L’augmentation de la croissance est due à une amélioration significative de la teneur relative en eau de la culture. Ces techniques résultent, également, en une augmentation du rendement (20 et 22.4 t/ha) et ses composants et une amélioration du calibre des fruits qui atteint 10.3 g pour les plantes traitées par Magiko comparé à 8.8 et 8.3 g, respectivement, pour DW et témoin.
