This study was conducted to evaluate a newly introduced chemical insecticide (Kanthion 50% E.C), and locally available botanicals. Each treatment was replicated three times and the entire setup was arranged in a randomized complete block design (RCBD) under field conditions. In the field, among the botanicals tested, N. tabacum, A. sativum, and lemon extract resulted in the highest percentage of nymphs and adult mortality greater than 65% within three days after application. In the field, non-treated control plants showed low yield as compared to the chemical, and botanical insecticide. The highest fresh weight (3.01 kg) was obtained from plants treated with Kanthion 50% E.C. This study indicates that Kanthion 50% E.C, N. tabacum, A. sativum, and Citrus limon could be recommended as an alternative management option against Brevicoryne brassicae (L) under field conditions.","PeriodicalId":488813,"journal":{"name":"Journal of Global Agriculture and Ecology","volume":"37 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139004599","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}

{"title":"Geo-information Technology-Based Suitability Site Selection for Temperate Fruits of Apple, Peach, and Plum in Tigray Region, Northern Ethiopia","authors":"Esayas Meresa, Yikunoamlak Gebrewhid, Gebremedhin Berhe, Tadesse Abadi, Gebrezgabher Tsehaye, Gebru Eyasu","doi":"10.56557/jogae/2023/v15i28465","DOIUrl":"https://doi.org/10.56557/jogae/2023/v15i28465","url":null,"abstract":"Introduction:  Growing temperate fruits in its appropriate region is important for growers and is used as a means of improving agricultural production, helps to improve livelihood of the community and source of income. The land needs to careful and appropriate use that is vital to achieve optimum production and productivity, and to guarantee environmental sustainability for the future generation. This requires an effective and up to date land information for effective utilization, management, and for decision making purpose. All agricultural crops, needs their ecological requirements for modelling the spatiotemporal distribution of land suitability potential and for performing agricultural activities effectively and accurately. There is a problem related to proper site selection for growing temperate fruits in the Tigray region and to solve this problem GIS-based suitability site selection for growing temperate fruit trees is important for getting better production and to help in improving the livelihood of the community. \u0000Methods: To identify the ecological requirements, for growing temperate fruits considers the physical, meteorological, and landscape environmental factors. To come up with the best suitability regions, physical, meteorological, and landscape spatial layers of the study area were collected from different primary and secondary data sources and stored in a personal geodatabase with the same resolution, cell size, and projection system. After collecting the important parameters, reclassification of these factors and using their influences, overlay analysis was performed to get the potential suitability sites for apple, plum, and peach fruits, and the model result was validated using ground control points. \u0000The Results: According to the overlay-based suitability modeling approach, suitability sites of these low chilling temperate fruits were identified and mapped. Apple has a potential of 21% as suitable land and 79% as an unsuitable area of the total area of 54,573km2, peach has a potential of 17% as suitable land and 83% as unsuitable land and plum has a potential of 27% as suitable land and 73% as unsuitable land in Tigray region. Around 50 ground control points (GCP) was collected from the ground, and 80% of the ground data were fitted with the suitability sites found from the overlay analysis modeling. \u0000Conclusion: This information was used as a baseline information for different agricultural experts, stakeholders, research organizations, NGO’s and policy makers for growing of low-chilling temperate fruits and getting a good production in the region.","PeriodicalId":488813,"journal":{"name":"Journal of Global Agriculture and Ecology","volume":"57 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010344","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}

Main objective of the study was to analyze the profitability of main season and off-season production of selected vegetables in Dhading district. Multistage sampling technique was used to select 60 respondents (commercial vegetable farmers) who were interviewed face-to-face administering a semi-structured questionnaire to collect primary data. Though the average cost of production of cauliflower and tomato in off-season was higher than in main season, net incomes from these crops in off-season were higher than in main season (p<0.01). Benefit-cost ratios of cauliflower and tomato in main season (2.09 and 1.13 respectively) were lower than in off-season (2.78 and 1.47 respectively). Results indicated that growing vegetables in off-season is more profitable than in main season. The major problems perceived by the commercial vegetable farmers in the study area were high fluctuation in market price of vegetables followed by disease and insect pest damage. Study suggests that off-season vegetable production can be used as better alternative for income generation taking advantage of premium price.  Government support to off-season vegetable production could make this business more profitable and sustainable.","PeriodicalId":488813,"journal":{"name":"Journal of Global Agriculture and Ecology","volume":"5 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138606878","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}
