Conservation agricultural practice is intended to conserve, improve and make more efficient use of natural resources. However, despite these potential benefits, CSA is only practiced in some areas of Ethiopia and has not been sufficiently adopted by smallholder farmers. Therefore, this experiment was intended to improve the production and productivity of maize through different moisture conservation practices and to determine and recommend the best moisture conservation practices for agro-pastoralists in Yabello District, Borana Zone. The field experiment was conducted at Qobo, Qadale and Colksa Kebeles of Yabello districts for two consecutive years, from 2019 to 2020, the main cropping seasons. The experiments had four treatments (Runoff diversion, Furrow, Runoff diversion plus Furrow and Control) laid out in a randomized complete block design (RCBD) of three replications. The analysis of variance showed that there was a significant difference among treatments in days to maturity, cob diameter, cob length, hundred seed weight and grain yield in all cropping seasons and locations. The highest grain yield was obtained from furrow with diversion structure treatment (5.83, 5.59, 4.2 t/ha), followed by diversion structure (5.51, 4.84, 3.9 t/ha) at Qadale, Colkasa and Qobo Kebeles, respectively. The lowest grain yield was recorded for the control (farmers practice) treatment (3.56, 3.05 and 3.36 ton/ha) at Qadale, Colkasa and Qobo Kebeles, respectively. In all sites, moisture conservation treatments (furrow plus diversion, diversion and furrow) have yield advantages of 2.27 t/ha (40.68%), 2.54 t/ha (45.44%), 0.84 t/ha (20%), 1.95 t/ha (35.39%), 1.79 t/ha (36.98%), 0.54 t/ha (13.84%) and 1.88 t/ha (34.55%), 2.02 t/ha (39.84%) and 0.36 t/ha (9.43%) more than farmer’s practices, respectively. Therefore, moisture conservation practices are recommended for optimum production of maize in moisture stress areas of Yabello District, Borana Zone.","PeriodicalId":514924,"journal":{"name":"World Journal of Agricultural Science and Technology","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141127145","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}

Abebe, Bikila Mengistu, Wondmagegn x Mengistu, Zerihun Dibaba, Baca Bultuma","doi":"10.11648/j.wjast.20240202.11","DOIUrl":"https://doi.org/10.11648/j.wjast.20240202.11","url":null,"abstract":"Agroforestry parklands are playing an important role, through trees and shrubs providing multiple products and important long-term ecological benefits. Purposive sampling methods were applied to select districts, PAs and farmers which mostly used parkland agroforestry practices. Based on information delivered from informal assessment result, formal survey was done with selected 84 HHHs (sample size) for the study purposes. Based on the existences of long lived parkland agroforestry practice and associated challenges four PAs from Ginir and Goro districts of Bale Zones were selected purposively with assistance of district agriculture office expertise and DAs. Survey results showed the presence of 17 woody species of trees and shrubs representing eleven (11) families at the study areas. Of seventeen (17) woody plant species retained/planted and managed on parklands, 82.4% were native. Fabaceae was the most dominant woody species family which accounted about 41.2% of the total number of species recorded. The Croton macrostachyus Hochst., Faidherbia albida, Cordia africana Lam., Acacia abyssinica Hochst., Junperus procera Hochst and Acacia species were the most frequently observed multipurpose woody species in the study area. Almost all of the respondents did practise different types of management activities or practices for the woody species they owned in parkland of the study areas. This finding revealed that pollarding (33.45%), coppicing (21.08%), branch pruning (35.56) and the rest thinning and protection woody species management practices were applied to the scattered trees on croplands of the study areas. On other side, respondents stated that the major challenges for the improvement of parkland agroforestry practices in the study area were instability of rain fail or drought (34.52%) and shortage of farmlands (21.43%). The finding of this study showed that agricultural landscapes (Parkland agroforestery practices) were the home/host of reasonable number of native woody species flora conservation or it’s almost the remnants of the natural vegetation. Therefore, further need for more comprehensive analysis of the multiple benefits and services provided by parkland trees located on farmlands or the interaction effects of the agroforestery components on soil fertility improvement, crop yields and quality in the future.","PeriodicalId":514924,"journal":{"name":"World Journal of Agricultural Science and Technology","volume":" 46","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140691663","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 qualitative methodology was employed in the case study, enabling the acquisition of concrete, contextual, and comprehensive knowledge regarding the environmental governance that Peru has been experiencing. The study subjects comprised 15 representatives of producer organizations from the coast, the Andes, and the Amazon, as well as 5 representatives of institutions associated with the agrarian and environmental governance of Peru. The semi-structured interview was conducted with them, complemented by a documentary analysis of the primary agricultural and environmental public policies. The results indicate an enormous gap in environmental governance between the three levels of government (national government, regional governments and municipalities) and between multisectors (the ministries dedicated to the themes are given: agrarian, environmental, social, and production) It has been concluded that there is no comprehensive vision for organic agriculture as an environmental sustainability strategy. The 'Theory of Anti-Lethargy of Small Farmers in the Face of Sustainable Governance' is proposed, which encompasses strategies to encourage agrarian participation, given that more than two million farmers are awaiting the government's intervention, i.e. citizens who have not comprehended the importance of being involved, active, and committed. This approach has the potential to generate economies of scale, enhance opportunities, and elevate living standards for the next generation.","PeriodicalId":514924,"journal":{"name":"World Journal of Agricultural Science and Technology","volume":"96 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140448546","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}
