Heavy metal concentration in the compost was also investigated. The specific objectives were to asses and evaluate nutrient contents of farmers practiced composts prepared from diversified material sources and to make data base for composting processes. A total 213 samples were collected from Bedele, Gechi and Dabo district by random sampling methods from a representative sites. The pH, moisture content, OC, TN, C:N ratio, exchangeable Ca and Mg, Available P, EC, Mn, Fe, Cu and Znwere analyzed according to a standard laboratory procedure. An average OC and OM content of farmer practiced composts were 10.1, 13.9 and 12.1% and 18.9, 23.96 and 20.86% in Bedele, Gechi and Dabo Hana respectively. An average Moisture content of compost prepared in the study areas were 7.2, 7.6 and 6.2 for Bedele, Gechi and Dabo Hana respectively. Moisture content of compost prepared in these three districts were below the standard range. This may be caused due to the problem of watering during compost preparation. An average electric conductivity of composts were 1.5, 1.1 and 1.2 in Bedele, Gechi and Dabo Hana disticts respectively. The majority of the macro and micronutrients were analyzed for compost collected from Bedele, Gechi and Dabo Hana district were below the recommended range. This is due to unbalanced substrate during compost preparation especially absence of legume materials or residue from mixing materials.","PeriodicalId":310130,"journal":{"name":"American Journal of Agriculture and Forestry","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126010873","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}

However, many farmers were not food secured and only few model farmers used tef for their daily local food. This is due to the use of low yielder varieties. On the other hand, improved tef varieties were not disseminated for surplus production. Therefore, it is important to find the way of improved tef varieties were disseminated in potential areas of Guji zone. This activity was conducted to popularize improved Dagim tef variety, strengthen stakeholders’ linkage and to improve farmers’ income. Purposively, Adola Rede, Odo Shakiso and Wadera were selected based on their tef potential and suitable for monitoring. Seven (7) kebeles were selected from the selected districts. Totally, 83 farmers were selected for pre scaling up tef at the midlands of Guji zone. In addition, four FTCs were used as multiplication site as a seed source for the next season. 400kg of Dagim variety was distributed. Each farmer was obtained 4.5kg Dagim variety and sown it on 0.25ha. Training was used to enhance farmers’ knowledge and skills on Dagim production and field day was used to motivate farmers to grow Dagim tef variety. The stakeholder had participated during training and field day to strengthen linkage on seed, agricultural inputs and information. Hand weeding and herbicide was used to control weed. Yield, cost of production and farmers perception were collected by interview method. Data was analyzed by descriptive statistics, net income and narration. The yield performance of Dagim variety was 9.82 qt/ha which low compared to national and demonstration stage due to lack of rainfall during 2020 and 2021/22 year. The result of net income showed that production of Dagim variety generated a return of 15735.72 ETB/ha. More net income (17551.63 ETB/ha) was obtained at Odo Shakiso district followed by Adola Rede district (16503.36 ETB/ha). There was a good yield and income at some farmers who sown Dagim variety at mid of September month. Dagim variety should be disseminated in the midland districts of Guji Zone. Since tef can be produced twice in a year provision of tef variety and fertilizer for farmers should available based the seasons.","PeriodicalId":310130,"journal":{"name":"American Journal of Agriculture and Forestry","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132664091","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}

Potential land is covered by crop production to feed the increasing human population. Hence, for livestock production feed production is challenging to be solved at farm level. Therefore, balancing the available land for crop and livestock production is critical as the land is fixed resource. This could be achieved by demonstrating year round forage production on small area. This activity was conducted at highland districts of Guji zone to evaluate biomass yield of Desho grasses and to enhance the knowledge and skills of farmers on production of Desho grass. Areka DZF № #590 and Kindo Kosha DZF № #591 desho grasses were planted on 5m×10m with the recommended packages. Knowledge and skills of farmers were taken before and after demonstration. Training and mini field day was organized. Cutting and carry system was used to feed livestock. Measurement, observation and interview were used to collect the data. Plot cover, plant height regeneration and fresh biomass were collected. 17 Knowledge and skills questions were prepared and interviewed to 18 farmers before and after demonstration. Descriptive and t tests were used to analysis the data. The result of descriptive showed that Kindo Kosha DZF № #591 variety had more plot cover (88.47%) than Areka DZF № #590 variety (85.76%). As desho grass is annual forage and regeneration trait was important for livestock feed. Kindo Kosha DZF № #591 variety also provide high in regeneration capacity (85%) than Areka DZF № #590 (83%). More fresh biomass was obtained from Kindo Kosha DZF № #591 (49.78t/ha) than Areka DZF № #590 (47.59t/ha). The result of paired sample test showed that there was a mean significance difference in knowledge and skills before and after on demonstration of desho grasses at 0.001 level. Knowledge and skills of farmers were increased by trainings and field days organized on desho grass demonstration. Both desho grasses were identified and preferred for livestock feed by experimental farmers. Desho grasses were important as feed, soil erosion control and as income generating. Therefore, it is better to pre scaled up these desho grasses at highland areas of Guji zone. To know more advantage of desho grass as livestock feed further research is needed on the effect of desho grass on milk and meat production at the study areas.","PeriodicalId":310130,"journal":{"name":"American Journal of Agriculture and Forestry","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126245808","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}

However, information on the status of baobab populations in this area is insufficient. The aim of this study is to characterise the baobab parks in this area from a biophysical point of view. To do this, the sample involved 756 baobab trees, 89 of which were in hut parks, 223 in villages and 444 in the bush. The parameters assessed on each baobab tree were circumference at 1.3m, total height, crown diameter, number of primary branches, distance between individuals, level of fruiting and signs of anthropisation. The data were subjected to an analysis of variance with the ANOVA test followed by the Student Newman Keuls test at the 05% threshold. The results showed a significant difference (Pvalue <0.05) between parks for each parameter except circumference at 1.3m. The village parks had the highest values for circumference at 1.3m (5.27±2.12m), for crown diameter (14.06±6.62m) and for distance between baobabs (19.12±8m). On the other hand, the tallest baobabs (37.79±8.93m) with the highest number of primary branches (22±14) are observed in the bush parks. According to the structural analysis, the majority of the parks (<50%) have large baobabs. The hut and village parks are dominated by the height and diameter classes of [25-35] m and [5-10] m respectively. On the other hand, in the bush parks, the most represented baobabs are found in the height <35m and diameter [1-5] m classes. Furthermore, the results on fruiting showed that bush parks have more baobabs with a high level of fruiting. Also, concerning anthropisation, high rates (more than 52% of baobabs) were noted for each type of park. These results show an ageing baobab population threatened by strong anthropic pressure. Thus, efforts should be made to ensure the survival of these baobab populations, which are essential to the life of local populations, through better management.","PeriodicalId":310130,"journal":{"name":"American Journal of Agriculture and Forestry","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114521267","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}

Therefore this study was conducted to determine P fertilization rates and the relative effectiveness of different placement methods on the yield, P uptake of maize and concentration of P in the soil. The experiment was carried out at Bedele district. Four level of P fertilizer (0, 23, 46 and 69 P2O5 kgha-1) and three placement methods of P application (broadcasting P and seeds, surface banding P to the side of the seeds, and deep band P fertilizer below the seeds) were implemented as treatments with three replications in randomized complete block design. Dry biomass, grain yield, straw yield, harvest index, residual soil P, and total P in grain were highly significantly (P< 0.01) influenced by effect of P fertilizer rates and placement methods. Total P in the soil significantly (P<0.05) influenced by placement methods. Mean plant height, total N in the grain and total N in the stalks highly significant (P<0.01) influenced by effect of P fertilizer rates and its placement methods. The mean days to maturity highly significantly (P<0.01) influenced only by P fertilizer rates. The highest grain yield (78.40 qt ha-1) and biomass yield (142.11 qt ha-1) were noted from surface banding of P fertilizer to the sides of the seeds at application of 69 P2O5 kg /ha respectively when compared with the no P2O5 application. However, P and N uptakes by Maize ranged from 0.84% with no P2O5 to 1.32% at the rate of 69 kg P2O5 ha-1 and 0.656% with no P2O5 to 1.04% at rate of 69 kg P2O5 ha-1, respectively. Also, the residual soil P after harvest of the maize ranged from 1.312 with no P2O5 to 11.79ppm was recorded at application of 69 kg P2O5 ha-1.
