The study followed a qualitative research methodology; thus, observation and documentation of each series of planned activities, semi-structured and unstructured interviews with the executive leaders of national agencies and international partners, and discourse analysis of the shared presentations and knowledge exchange between or among the stakeholders were conducted to surface specific themes that described how this stakeholders’ forum enhanced the implementation of integrated water resources management in the country through a multipartite communication platform. The research findings revealed that international and national partnership is fortified and R&D efforts will be rapidly realized through a multipartite information exchange, collaborative workshop, technology transfer, and other knowledge-sharing activities. Moreover, legal agreements entered by all stakeholders to scale up global and community linkages are a salient measure to encourage and motivate stakeholders to take part in the implementation of STI-based efforts stipulated in such legal documents. Joint field visits, series of fellowships, and use of websites for information dissemination also have pivotal roles in acquiring a profound understanding of dam situations in the Philippines and Japan, and how integrated water resources management will be communicated to various community partners. Thus, the forum served as a channel that bridged what the government agencies and organizations know about flood and sedimentation management and what the community partners need to understand to revitalize science-community-government-academe collaboration.","PeriodicalId":500203,"journal":{"name":"Journal of environmental and agricultural studies","volume":" 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680269","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 study aimed to determine the timing and concentration of gibberellin administration that is most effective in stimulating melon plants' vegetative and generative growth in a substrate hydroponic system using the drip fertigation method. This research was carried out from May to August 2023 in Kragilan Surakarta. This study was conducted using a one-factor Complete Randomized Design (RAL) that has seven levels based on the method of gibberellin application, namely Level 1: G0 without Gibberellin (Control). Level 2: G1 Gibberellin concentration 60 ppm sprayed on days 5, 10, and 15 hst. Level 3: G2 Gibberellin concentration 60 ppm sprayed on day 20,25,30 hst. Level 4: G3 Gibberellin concentration 80 ppm sprayed on day 20,25,30 hst. Level 5: G4 Gibberellin concentration 80 ppm sprayed on day 30,35,40 hst. Level 6: G5 Gibberellin concentration 100 ppm sprayed on day 30,35,40 hst. Level 7: G6 Gibberellin concentration 100 ppm sprayed on day 30,40,50 hst. The results showed that application of gibberellins with concentrations of 100 ppm at 30,40 and 50 days after planting (HST) resulted in significant differences in chlorophyll content of a+b (total) compared to applications of concentrations of 60 ppm, 80 ppm, and 100 ppm at different times. There was a significant difference in sweetness compared to applying GA3 at concentrations of 100 ppm at different times. The application of GA3 did not significantly affect chlorophyll a, chlorophyll b, fruit diameter, fruit weight, root weight, and crush weight in melon plants based on Hydroponic systems using drip fertigation.","PeriodicalId":500203,"journal":{"name":"Journal of environmental and agricultural studies","volume":"87 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139530442","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}

The present study was conducted to evaluate the performance of elite sunflower cultivars under Kabul agro-ecological conditions. The main objective of this research is to identify superior genotypes best adapted to Kabul agro-ecological conditions. Three improved cultivars of sunflowers, two from France (Robiacs and Imeriacs) and a local one were tested for two years, 2018-19, on the farm of Agriculture faculty at Kabul University. The experiment was arranged in a randomized complete block design (RCBD) with three replications. Data were collected on achene's yield and other parameters. Analysis revealed a highly significant difference among cultivars for all parameters under study except the number of days to complete emergence, number of plants m-2, plant height and leaf area index. Among the cultivars examined, there were significant differences in achene yield. Local cultivar (4696.92kg ha-1) followed by Robiacs (4346.62 kg ha-1) yielded significantly higher than Imeriacs cultivar (3029). These cultivars have shown to be the best local and exotic genotypes in terms of achene's yield. With additional tastings, these potential lines could be released for specific environments in Afghanistan similar to the Kabul agro-ecology.","PeriodicalId":500203,"journal":{"name":"Journal of environmental and agricultural studies","volume":"1 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136381920","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 examines the issues faced by the disabled, particularly the physically challenged, who live in Afghanistan's cities in order to achieve this goal. The government's existing laws and regulations also include preparing for these issues. A descriptive-analytical approach has been adopted in the investigation. In this regard, the researcher has utilized the library study method to explain the concepts and give a theoretical framework to assess the course of domestic legislation after evaluating the development of domestic and international laws. This article comes to the conclusion that the physical and administrative requirements of disabled people cannot be met in Afghan cities. Think about the sidewalks. In reality, a wheelchair user is unable to use the sidewalks. Wheelchair users' rights have been violated as a result of the obstacles that the town has put in place to keep motorcycles off the pavements. Think about the sidewalks; in reality, a wheelchair user cannot utilize them. The right of wheelchair users has essentially been infringed due to the obstructions put in place by the municipality to prevent motorcycle riders from using the sidewalks. There are few organizations in the road and construction engineering sector, particularly in government departments, that have measured the essential facilities and measures for the disabled in their structures. The law of motion is one of the acknowledged tenets among philosophers. They hold the view that everything in the universe is in motion and that each living thing is gradually evolving to realize its potential. Therefore, all facets of society should have access to the amenities required for advancement. This rule applies to everyone, including those with disabilities, and the urban environment must be created and modified in a way that allows them to utilize all of its amenities. The road system in every city is what connects all of the metropolitan areas, and by making it accessible to people with disabilities, many of their difficulties are resolved. In cities, disabled persons are assessed. The necessary design requirements for people with disabilities are then presented.","PeriodicalId":500203,"journal":{"name":"Journal of environmental and agricultural studies","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136210780","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}
