However, the type of growth media used affects both larval body composition and growth performance. Using recycled organic materials from chicken manure (CM), cow dung manure (CDM) and rabbit manure (RM), the present study evaluated the production of red worms that could be used as a substitute protein source for fish meals. Two experiments were conducted, the first experiment tested the compatibility of each organic manure when mixed with soil separately, whereas the second experiment combined the three organic manures with a fixed amount of soil. The study was conducted for 60 days. The findings showed that red worms reared on 100 % CM had a significantly higher body weight (19.27 ± 0.9 g) followed by those reared on 100 % CDM and 75% RM, whereas red worms reared on 100 % RM had the lowest body weight (4.9 ± 0.1 g). A combination of 20% CM + 40% CDM + 20% RM + 20% Soil supported significantly higher body weight of red worms (24.9 ± 1.1 g), while the lowest value of body weight (5.1 ± 0.2 g) was in a combination of 20% CM + 0% CDM + 60% RM + 20% Soil). Furthermore, the results revealed that red worms reared on 100 % CDM without soil as waste substrate had the highest crude protein (73.28% DM) compared to red worms reared on other types of substrates. The study suggests the potential of reusing organic manure such as chicken and cow dung manure at different inclusion levels in the production of red worms.\u0000","PeriodicalId":7466,"journal":{"name":"Agriculture, Forestry and Fisheries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141832764","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}

Sorghum landraces are particularly crucial in crop-livestock mixed farming, however, the extended growing periods (6-8 months) required for these landraces make the crop vulnerable to recurrent drought events associated with delayed rain, dry spells, and drought during critical stages. The landraces are usually planted in March or April depending on the onset of rainfall and harvested around November but often fail due to drought. In such situations, early-maturing improved varieties are an option for farmers but access to seeds of these improved varieties is a challenge. Unlike the landraces, the improved early maturing varieties are planted around the first weeks of July and harvested in November. The formal seed system multiplies only a limited amount of improved sorghum seed, which is rarely available to smallholder sorghum growers, mostly as part of a government package for targeted programs. Therefore, a community-based seed multiplication (CBSM) scheme was introduced to address seed shortages among smallholder sorghum farmers. After a successful experiment in 2015 aimed at enhancing seed multiplication by smallholder sorghum farmers, the process was further implemented on a larger scale using the CBSM scheme. Between 2016 and 2017, three CBSM farmer groups consisting of a total of 56 participants were established in three districts of West Hararghe, Ethiopia. Seeds of two early-maturing and drought-tolerant improved sorghum varieties (Dekeba and Melkam) were multiplied on a total area of 49.58 hectares, resulting in 215.6 tons of certified seeds. The study's findings indicate that the CBSM scheme enhanced smallholder farmers' sorghum yields, incomes, and climate resilience by providing high-quality seeds, expanding access to improved seeds, improving crop quality, and empowering communities to manage seed distribution. Partnerships with local organizations and government agencies were vital for success, allowing the scheme to reach more farmers in different regions. The scheme proved successful for smallholder sorghum growers in Ethiopia's dry lowlands, offering lessons applicable to similar challenges elsewhere, and promoting sustainable solutions for smallholder farmers.\u0000","PeriodicalId":7466,"journal":{"name":"Agriculture, Forestry and Fisheries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141833026","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 objective of the study was to characterize baseline information on the existing biophysical resource used as benchmark for planning and impact monitoring and to identify and major constraints and potential in the watershed. The watershed was selected depending on agro-ecological representation, prevalence of resource management and land degradation problems and accessibility for intensive follow-up. Based on the preliminary outlet identified during the watershed selection process, the watershed boundary was delineated using GPS data and the map of watershed was geo-referenced and digitized for its contour, roads, rivers, and other features. Both primary and secondary data were used for the study and primary data was collected through field observation, household survey, focus group discussion and interview of the key informants. From the total 103 household heads living in the watershed, 62 household heads were selected as a respondent for the study. The collected data was managed and analyzed using Statistical Package for Social Sciences (SPSS) and Microsoft excel 2010. The results of the study showed that about 29.4% of the watershed slope was characterized by flat lands, 45.7% moderate slope and 24.9% steep lands. As well as soil fertility status of cultivated land in the watershed were 33.9% low, 55.9% moderate and 10.2% high. The results of the study showed that the major constraints identified by sampled household heads were decline of soil fertility, soil erosion, climate change, land shortage, and deforestation were significantly contributed to the low crop yield in the watershed. About 27.4% of the sampled households had encountered decline of soil fertility problems, 25.8% of sample farmers encountered soil erosion problem, and 22.6% of sample farmers encountered climate change problem in the watershed. From the identified major constraints, the highest priorities were given for decline of soil fertility, soil erosion problem, shortage of feed and fodder, and decline of crop productivity respectively.

{"title":"Effect of Spacing of Elephant Grass Intercropping with Alfalfa on Biomass Yield and Nutritive Value of Elephant Grass in Fedis District, Eastern Ethiopia","authors":"Worku Bekuma, T. Zewdu, Meseret Girma","doi":"10.11648/j.aff.20241303.13","DOIUrl":"https://doi.org/10.11648/j.aff.20241303.13","url":null,"abstract":"The study was conducted by Fedis Agricultural Research Center (FARC) at Boko station in Fedis district. The experiment consisted of three different spacing arrangements: S1 (100 cm x 50 cm), S2 (75 cm x 50cm) and S3 (50 cm x 50 cm), and two cropping systems (intercrop and sole planting). These treatments were combined in a 3 x 2 factorial arrangement using a randomized complete block design with four replications. Forage samples were collected at ninety (90) days for elephant grass and 10% flowering for Alfalfa. The results showed that spacing and the interaction between spacing and intercropping had a significant (p<0.05) effect on herbage dry matter yield (DMY) and crude protein yield (CPY) of elephant grass. However, intercropping had no significant (p>0.05) effect on herbage DMY and CPY. Intercropping can increase the yield of herbage dry matter and total herbage dry matter when compared to pure stand elephant grass. The yield advantage can be up to 3.18% and 19.65%, respectively. Spacing does not significantly affect the dry matter yield of Alfalfa, but the cropping system does. Intercropping and narrow spacing resulted in higher total dry matter yield, due to the additive effect of intercropped Alfalfa dry matter yield. Among the three different spacing, the narrowest spacing S3 recorded the highest dry matter yield (25.62 t/ha), followed by S2 (22.28 t/ha) and S1 (18.33 t/ha). Spacing and intercropping have no significant effect on the chemical composition of elephant grass, but intercropping can increase the dry matter and decrease the ash content of elephant grass. Farmers in the study area and other regions with similar agro-ecology are advised to consider intercropping Alfalfa two weeks after establishing elephant grass. This should be done at an inter and intra-row spacing of 50 cm to achieve a higher herbage dry matter yield for both, elephant grass and total forage.\u0000","PeriodicalId":7466,"journal":{"name":"Agriculture, Forestry and Fisheries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141388215","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}

Broom-rape, <i>Orobanche crenata</i> Forsk (Orobanchaceae), present great threat parasitic weed to some crops in Egypt including faba bean. Egyptian farmers were forced to abandon growing faba bean crops due to <i>O. crenata</i> heavy soil infestation. Several methods have been used for controlling this parasite, but without obvious success. Many researches have shown that intercropping has been more effective than monocropping in suppression of parasitic weeds. The effect of intercropping (fenugreek, radish and flax) using two resistant cultivars (Giza 843& Misr 3) on the emergence of the broomrape spikes and faba bean production were carried out. Intercropping flax or fenugreek among faba bean cultivars, caused a significant reduction in the infestation levels of <i>O. crenata</i> and increased the faba bean yield compared with sole treatments. Flax was more effective in the reducing infestation rate by <i>O. crenata</i> than fenugreek. This reduction appeared to be related to reduced seed germination which may have been as a result of allelochemicals released by fenugreek roots, though this was not confirmed in this study. The reduction in weed infestation was more pronounced in Giza 843, than in Misr 3. Flax treatment showed the lowest weed infestation compared with other intercropping treatments. Fenugreek intercropping treatment resulted in the highest pod yield for both Giza 843 and Misr 3. Using resistant cultivars intercropping with fenugreek or flax is very promising trend that generally combines both good yield and low number of emerged spikes that reduce broomrape seed bank in the infected soils, with variations depending on the cultivar and growing season.","PeriodicalId":7466,"journal":{"name":"Agriculture, Forestry and Fisheries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140750916","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}

To provide such information, this study was therefore carried out to determine the effect of weight at first mating on the performance of the New Zealand White rabbit population at the University of Benin Teaching and Research Farm. The rabbits were grouped into four based on their weight before the first service (1.00 to 1.49kg, 1.50 to 1.99kg, 2.00 to 2.49kg, and 2.5kg and above) as weight groups 1, 2, 3, and 4 respectively. The rabbits were raised under acceptable management. The experimental animals were fed a commercial diet of 18% CP and 2700kcal/kg ME. Data collected were weight of doe before service (WBS), number of time served (NTS), litter size at birth (LSB), litter size at weaning (LSW), litter weight at birth (LWB), litter weight at weaning (LWW), pre-weaning mortality percentage (PWM), gestation length (GLT), and stillbirth (SBT). The data were subjected to statistical analysis using the R statistical package version 3.3.3 (2017). Significant means were separated using the Duncan Multiple Range Test. The results obtained showed an increasing trend with body weight at first service. The mean values for LWB were 40.08±1.04, 43.83±2.16, 49.26±2.93 and 45.57±3.74 g for weight groups 1, 2, 3, and 4, respectively. Rabbits in weight 2 and 3 had a higher CV of 30%. Mean LWW ranged from 366.20±26.92 in group 1 to 442.90±29.74 in weight group 4. The average LSB was 4 kits. Litter sizes at weaning (LSW) were 3 kits except for group 4 with 4 kits. The body weight at first mating had no significant effect (P>0.05) on the performance traits. Gestation length (GLT) and pre-weaning mortality (PWM) showed significance (P<0.05). Gestation length (GLT) was highest in weight group 4 with mean days of 32.14±0.40 and the least in group 3 (30.53±0.09).

Currently, soil acidity in highland portions of Western Oromia, including Gimbi, Nedjo, and surrounding areas, is a major problem that can impede agricultural productivity. Reviewing the mechanisms of soil acidification, which can affect soil nutrient availability and agricultural production, as well as management choices, were done in this context for this review topic. The main causes of acid soils are leaching of exchangeable basic cations and topsoil erosion caused by high temperatures and heavy rains, which promote the loss of organic matter the most. In most of Ethiopia's highland regions, the removal of agricultural waste and ongoing use of inorganic fertilizers that produce acidity are major factors in the development of soil acidity. Al and Mn toxicity are caused by acid soil, which also reduces nutrient availability. Furthermore, agricultural yield decreases due to acidity in the soil. The management options for acid soils include crop types resistant to Al toxicity, liming, and the use of organic materials as integrated forms of soil fertility control. Therefore, lime and organic fertilizers should be employed as crucial agricultural techniques for small-holder farmers in acidic soil locations in order to decrease the effects of soil acidity.","PeriodicalId":7466,"journal":{"name":"Agriculture, Forestry and Fisheries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140751924","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}
