These dysfunctions, aggravated by climate change, require the implementation of ecological engineering strategies to rehabilitate the soil. The soils of the South Cameroonian plateau suffer significant degradation in terms of loss of fertilizing elements due to extensive agricultural practices, which limits agricultural production. This work showed how tree legumes contribute to improving the yield of yellow yam (Dioscorea cayenensis) in the South Cameroonian plateau, to ultimately support the production of agroecosystems in this environment. Within the framework of this study, an experimental set-up was designed to measure the performance of tree legumes in the field. The experimental set-up is a randomized complete block trial with three treatments and three replications on 3000 m2. The control plot without shrubs, the plot with Calliandra, and the plot with Senna. This trial was carried out in the district of Mbankomo, Mefou, and Akono Department, Central Region. After monitoring the experiment, it was found that Senna spectabilis produced more nutrients than Calliandra calothyrsus. Thus, each Senna shrub produced 1.54 kg of litter in the first year and 2.04 kg in the second year for a quantity of nitrogen of 192.76 kg/ha and 260 kg/ha respectively in the first and second year. Each Calliandra shrub produced 1.46 kg and 1.87 kg of litter for a nutrient amount of 183 kg/ha and 236.81 kg/ha of nitrogen during the two years of the experiment. The combination of tree legumes and field crops increased yam yields by a factor of 2 or 3 compared to traditional agriculture. The growth rate of the yam is accelerated as well as its vegetative cycle, which is reduced from 7.5 months to 6 months as a result of the increase in soil organic matter through the shrub legume litter. Agroforestry practices could have a positive impact on soil characteristics and microbial communities, resulting in enhanced soil fertility and long-term sustainability of agricultural production. According to the results obtained, the insertion of tree legumes in agrosystems is a more efficient and less costly way to gradually and sustainably increase nitrogen availability and soil fertility.","PeriodicalId":14038,"journal":{"name":"International Journal of Environment, Agriculture and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84753542","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}

It is shown that an increase in the concentration of CO2 in the atmosphere, as well as an increase in its average temperature, correlates well with an increase in the number of natural disasters and, accordingly, an increase in budget costs for the removal of their consequences. On the other hand, the impossibility of completely stopping global climate change, let alone returning to its 1970 parameters, is discussed, for example: removing billions of tons of CO2 from the Earth's atmosphere; restoring trillions of tons of ice at the poles of the Earth and its mountain peaks; reduce the acidity of the waters of the World Ocean and its cooling. Hence the conclusion is made about the inexpediency of spending hundreds of billions of dollars on \"the fight against climate change\" and the expediency of spending these billions on the urgent adaptation of mankind to an already changed climate. Further, the article examines in detail the ways and options to prevent the destruction and loss caused by hurricanes, flooding, wildfires, massive burning of fossil fuels, traditional agriculture, as well as huge pollution of the World Ocean: replacement of fossil fuels with green energy and green transport, the construction of only hurricane-resistant and fire-resistant buildings in hazardous areas, the construction of dams and powerful drainage systems in areas of probable flooding, the transition to superconducting underground electrical cables, the widespread use of small modular low-enriched uranium nuclear reactors, widespread use of heat pumps, the transition from traditional cattle breeding to artificial meat, the widespread in agriculture use of so-called vertical farms, minimization of food losses at all stages, and more. The main idea of this report was clearly expressed by Charles Darwin in his well-known quote: “It is not the strongest and smartest who survive but the one who adjusts best to the changing environment.” That is, not the strongest nation (with the largest GDP), not the smartest nation (which will learn to extract all the excess CO2 from the atmosphere), but the nation that is best adapted to live in this changed climate (with hurricanes, floods, droughts, wildfires, etc.) - will have more chances to survive.","PeriodicalId":14038,"journal":{"name":"International Journal of Environment, Agriculture and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84548772","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}

Supplemental LED night lighting improves its growth, however the underlying molecular mechanism remains unknown. The study analyzed the transcriptome of H. brasiliensis plants under the treatment of LED night lighting. The light treatment resulted in 1047 and 411 differentially expression genes (DEGs) during the day and night time, respectively. Functional group analysis showed that DEGs in the day time enriched into 185 metabolic pathways and that DEGs in the night time enriched into 116 metabolic pathways. A total of 92 DEGs were identified between night lighting and control plants. These DEGs were involved in regulation of pigment metabolism, photosynthesis, circadian rhythm, and carbohydrate metabolism. The genes associated with circadian rhythm were altered during the day and night time. The gene involved in carbohydrate metabolic process was upregulated and the related KEGG pathways associated carbohydrate metabolism were upregulated. These results concluded that supplemental LED night lighting improve growth of hevea plants by upregulating genes associated with photosynthesis and carbohydrate metabolism, so as to synthesize more carbohydrates.","PeriodicalId":14038,"journal":{"name":"International Journal of Environment, Agriculture and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88757433","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}

Moench) in bituminous soils of selected communities (Loda, Lofo and Legbogbo) in Irele, southern Ondo State for two consecutive growing seasons (2020 and 2021). The Legbogbo site, which of very low bitumen, serves as the control. The textural class is sandy loam and the soil is acidic. Some samples of soil were collected from three dug soil profile pit at depths 0-100 cm at an interval of 10 cm and moved to the soil laboratory for the analysis of the chemical concentrations of macro and trace elements. The highest value of the heavy metal was recorded at Loda. More so, the least amount of the bitumen concentration was recorded at Legbogbo site (control) and in some cases at Lofo site. Result from the study showed that there is significant difference (P < 0.05) in the values of the heavy metals among the location at all depths. The results from various locations also showed that the soil depth and location were significant (P < 0.05) in their main effects on the soil heavy metals. It was observed that the heavy metal concentration of soil was lower than the permissible limit, an indication that the concentration of heavy metals of the study areas may not have negatively influenced the growth and yield of okra. All agronomic parameters in all locations during the two seasons of experiment were in the way of Legbogbo>Lofo>Loda. Okra had 0 kg.ha-1 pod yield at the Loda site at both 2020 and 2021 growing seasons, while Legbogbo had the greatest fruit yield for both seasons.

The potential agricultural products in Blitar Regency have inefficient and complex supply chain because they involve many actors from farmers to consumers. The inhibiting factors are as follow: 1. The farmers do not have a collective system for marketing their crops so that information about the products as well as the prices are not integrated, 2. The supply chain patterns are inefficient and complex, so that the prices are costly, and 3. Inadequate location of the wholesale market.
