influence of Microorganisms Effective against Basal Rot and on Agronomic Parameters of Onion [Allium cepa L. (Amaryllidaceae)]

Journal of Agricultural Chemistry and Environment 2024年第3期13卷 282-299页

作者： Henriette Doukahonon Guigui Bi zaï Pacôme zaouli Alain Serge Coulibaly Juliette Ky Dedi Training and Research Unit of Sciences of Nature Laboratory of Biology and Improvement of Plant Production Nangui Abrogoua University Abidjan Cte dIvoire Department of Plant Biology Training and Research Unit (UFR) of Biological Sciences Peleforo Gon Coulibaly University Korhogo Cte dIvoire

Onions are a horticultural crop of great economic, dietary and medicinal importance, and are highly prized by the ivorian population. However, production remains low, due to a number of constraints, including parasitic attacks. The most frequent is fusariosis caused by Fusarium sp., a pathogen that causes enormous damage to onion crops. Faced with these attacks, chemical control appears to be ineffective, with consequences for human health and the environment. This is why the search for effective alternative methods that respect the environment and human health is so necessary. it is in this context that this study was carried out, with the general aim of controlling fusarium wilt in onion crops, with a view to improving onion production in ivory Coast through the use of effective microorganisms. The experimental set-up used for this purpose was a fisher block with complete randomiza.ion, comprising three replicates. A fungal spore concentration of 106 spore/mL of Fusarium sp., three doses (1%;2.5% and 5% v/v) of EM and one dose of a chemical fungicide (30 mL/16L) were tested on young onion plants. Each block consisted of nine sub-plots with nine treatments. Health parameters (incidence and severity) and agronomic parameters (growth and yield) were assessed. Microbiological analysis of the EM revealed the presence of nine morphotypes of Trichoderma sp., Aspergillus clavatus, Aspergillus flavus, Aspergillus sp., Penicillium sp., Rhizopus sp., lactic acid bacteria of the Bacillus family and the yeast Saccharomyces cerevisiae. Field experimentation showed that the 5% EM microbial solution reduced the incidence and severity of fusariosis compared with the chemical fungicide, and proved to be the best. This dose reduced yield losses by 7.14%, while improving onion growth and yield by over 5%. The results demonstrated the ability of the EM solution to effectively control the causal agent of basal rot in onion crops.

Journal of Rare Earths 2014年第7期32卷 633-640页

Terbium-picrate triethylene glycol（EO3-Tb-Pic） complex was prepared in thin film and single layer device structure of iTO/EO3-Tb-Pic/Al, using spin coating technique. The UV-Vis absorption spectroscopy analysis was performed to evaluate the electronic molecular transition of the complex. The optical band gap, Eg estimated from the Tauc model revealed that EO3-Tb-Pic thin film exhibited a direct transition with Eg of 2.70 eV. The electronic parameters of the iTO/EO3-Tb-Pic/Al device such as the ideality factor n, barrier height Φb, saturation current io, and series resistance Rs, were extracted from the conventional lni-V, Cheung＇s functions and Norde＇s method. it was found that the evaluated parameters calculated from Norde＇s and Cheung＇s methods were consistent with those calculated from the conventional i-V method. in the double logarithmic i-V plot, three distinct regions based on the slope were identified, and the conduction mechanisms were discussed and explained. The mobility, μ value was estimated from SCLC region as 2.58×10^–7 cm2/（V·s）. This newly obtained lanthanide complex may be potentially utilized in electronic devices.
