This study aimed at examining the views and attitudes of local farmers towards ‘planting, growing, and managing trees in agroforestry system’ in Basona Worena District, Ethiopia. As there was already a traditional agroforestry adopted by the farmers, the study kebele was purposely selected. A structured questionnaire was developed by accounting different socioeconomic variables. A total of 94 respondents were randomly contacted to collect the questionnaire data. Multiple linear regression technique was employed to analyze and interpret the data. Contrary to expectation, the findings showed that a greater proportion (about 60%) of the respondents did not practice agroforestry. However, those farmers who used to practice traditional agroforestry mainly exercised it to meet their household wood demands. Based on their economic values, the most commonly preferred tree species planted and grown by the farmers in descending order, included eucalyptus species, Acacia abyssinica, Croton macrostachyus, Sesbania sesban, Cupressus lusitanica, and Olea africana. The results also suggested that the farmers had conscious perceptions to determine the negative and positive effects of tree species on food crops, soils, and water. Generally, a greater proportion of the farmers strongly agreed (73.33%) that they had developed positive attitudes towards ‘planting, growing, and managing trees in agroforestry system’. Moreover, the multiple linear regression models showed that different socioeconomic variables significantly influenced the attitudes of farmers towards ‘planting, growing, and managing trees in agroforestry system’. Generally, the regression model explained about 36% of the variance in attitudes of the respondents towards ‘planting, growing, and managing trees’. Hence, providing improved agroforestry extension services, including incentives (e.g., seeds, tree seedlings, technical supports, and credits) may help increase the active participation of the farmers to adopt plant, grow, and manage trees in agroforestry system. Moreover, provision of adequate technical trainings on agroforestry technologies and establishing demonstration site is indispensable to increase the awareness level of the local farmers and thereby promote the adoption of agroforestry technologies in Basona Worena District and elsewhere.","PeriodicalId":396842,"journal":{"name":"Journal of Agricultural Science and Food Research","volume":"64 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133178494","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}

One of the best methods of clonal propagation is using the cuttings. There are many plants that can be propagated through cuttings and one of them is guava. Guava is popular in Pakistan. To ensure that a guava tree will produce fruits that belong to its original cultivar, this study was conducted. Softwood cuttings of guava were treated with IBA (1600 ppm and 2000 ppm), NAA (7000 ppm and 10,000 ppm) and IBA+NAA (1600+7000 ppm and 2000+10,000 ppm). There were five media used (Soil, Peatmoss+Soil, Sand+Soil, Baggasse+Soil and Soil+Peatmoss+Sand+Bagasse. The experiment was laid out using Completely Randomized Block Design (CRBD) with two-factor factorial arrangement. A total of 105 cuttings were used, each with 12 cm length and with 2-4 nodes. Media samples were collected and physio-chemically analyzed at the Soil and Water Testing Laboratory in Layyah, Pakistan to assess the properties and fertility status. Guava cuttings with 1600 ppm IBA showed the best results in terms of the number of roots, root length and days to sprout, followed by 7000 ppm NAA in Peat moss+soil and soil+peat mass+sand+bagasse. For the combination of growth regulators, the best results were observed in IBA 1600 ppm + NAA 7000 ppm. Poorest result in all parameters (days to sprout, number of roots, and root length) was recorded in control. The 1600 ppm IBA with 10 second dipping time for softwood cuttings of guava yielded best results in peatmoss+soil media for all the parameters tested. Hence, this study concluded that treatment with auxin (such as IBA) can yield best results and can help to solve the problem in propagating guava using cuttings.","PeriodicalId":396842,"journal":{"name":"Journal of Agricultural Science and Food Research","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131077535","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}

Data analyses involved descriptive statistics such as frequency counts, percentages, means and inferential statistics such as multiple regression analysis. A null hypothesis was tested at 5% level of significance. The result of the socio-economic characteristics of the respondents show that majority 50%, 35.7% and 44.6% of BESs, BEAs and EAs fall within active economic and productive age bracket of 35-44 years; while the ZEOs were between 45-54 years. Most of the ZEOs (100%), BESs (85.7%) and EAs (48.2%) were males; except among BEAs where majority (80%) were females. Greater proportion of 78.57%, 54.29% and 53.6% of BESs, BEAs and EAs were polytechnics and university graduates; who had worked for between 5-9 years with percentage values of 57.14%, 64.3% and 83.93% respectively. But, ZEOs had higher years of working experience of 15-19 and 20-24 years respectively.

However, there is a knowledge gap as to the impact of currently ongoing land use changes on soil organic carbon stock, which is an important rangeland ecosystem service, particularly in the face of climate change. Thus, this study was conducted to assess the effect of land use change on soil organic carbon stock in three land use types, namely, enclosures, communal grazing and cultivated lands in Borana rangeland. The result indicated that there were significant interactions between land use types and depths for soil organic carbon stock (p<0.0001) and bulk density (p=0.0055) with mean losses of 60% and 69% in soil organic carbon stock from the surface layer (0-10 cm) of communal and cultivated lands, respectively, as compared to enclosure land use type. The results indicated that communal grazing and crop cultivation in the Borana rangeland resulted in significantly decreased soil organic carbon stock. Hence, the current trend must be curbed to put back the system on its right track of resilience and sustainability for its long-term benefit and to mitigate the unprecedented increase in CO2. Therefore, the results of this study would be useful for the improvement of land use management in the future.","PeriodicalId":396842,"journal":{"name":"Journal of Agricultural Science and Food Research","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132428739","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}
