Forty eight cows were selected from the herd of Baggara cattle. The cows were weighed and divided into four groups A, B, C and D, each group comprised of (12) cows according to parity order, first, second, third and fourth parity. Data were analyzed by using F test for analysis of variance procedures and Duncan’s multiple range test (DMRT) for mean separation. All cows were raised on natural grazing. The results revealed that parity order significantly (p<0.05) affected daily, monthly and total milk yield. Milk production increased with advance parity. High (p<0.05) milk yield, monthly and daily milk scored by 3rd parities as 668.47 kg, 133.73kg and 4.49kg respectively. Results showed significant differences (p<0.05) between different parities for the milk composition during first and third month of lactation period, with high fat percentages in first month for 2nd parities (6.21) and 3rd parities (6.26) in 3rd month of lactation. The results indicated that calving days to first estrus and days to conceive were significantly (P<0.05) effected by parity number. Shorter days to show estrus was obtained by primiparous cows (56.19 ±8.72 days), also Days to conceive exerted significant (P<0.05) effect parity order.

The disease may cause substantial quantitative and qualitative yield losses but much of the work in Ethiopia on this pathosystem focuses on quantitative yield loss of durum wheat. This work was carried out at Debre Zeit Agriculture Research Centre during 2015/16 and 2016/17 main and off-seasons. Hence the current study was conducted with the objectives to quantify the amount of loss in grain yield due to stem rust and assess the relationship between disease parameters, grain yield, and physical quality parameters of improved durum wheat varieties grown in Ethiopia. Artificial inoculation was performed using a mixture of different dominant stem rust races. There were treated and untreated plots by fungicide that serves as protected and unprotected plots, respectively. Disease severity was recorded each 10 days interval and area under disease progress curve (AUDPC), terminal severity, and coefficient of infection were calculated. The tested cultivars exhibited different disease severity levels, having a mean value of 6.7-76%. High values of area under disease progress curve (AUDPC) were detected on Hitossa, Utuba (1225.7, 585.9). Whereas the lowest values of yield loss were recorded on CVS. Mangudo and Utuba have the mean value of yield loss of 40.2 and 44.8%, respectively. The highest yield loss was observed on susceptible variety Hitosa showing the mean value of 70%. Correlation coefficients were tested between yield losses and values of AUDPC, final stem rust severity, coefficient of infection, and rate of infection of the tested cultivars. There were strong correlation coefficients among disease parameters (r=0.72-0.99). There was also a moderately strong negative correlation coefficient among disease parameters and yield, hectoliter weight, and 1000-kernel weight of the test cultivars (r= -0.53 to -0.81). The current study indicated that the application of Rex Duo can be used in minimizing yield losses caused by the stem rust disease of durum wheat. Therefore, supporting the released durum wheat cultivars with fungicide application is the most pertinent issue in Ethiopia as most of the durum wheat cultivars in farmers' hands were moderately susceptible to susceptible cultivars Pgt races.","PeriodicalId":345521,"journal":{"name":"International Journal of Life Science Research Updates","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129643759","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, currently, farmers are not benefited and production and productivity of the fruits are being decreasing from time to time because of some constraints of them. Therefore this study was attempted to assess the production constraints of mango in the woreda’s.

Accordingly, data was collected from 90 randomly selected mango producing households in the woreda’s from three Kebeles namely Algela, Dareselam and Ashura. Focus Group Discussion and Key Informant Interview were made to organize qualitative data type. The result showed that disease, insect pests, bird damage, land shortage, lack of credit, high input price, limited knowledge, poor seed quality and weed were the core production and productivity constraints of mango in Homosha woreda’s. Therefore the policy makers should have to encouraging the researcher to release generation of disease and insect tolerant varieties of mango, strengthening extension services and also enhance knowledge and skills of smallholder farmers’ developmental endeavors should work and participate on the provision of improved crop varieties, input delivery, support research and development should be focused to improve the livelihood and economy of the farmers’.","PeriodicalId":345521,"journal":{"name":"International Journal of Life Science Research Updates","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115743814","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}
