Fruiting pattern of five Rauvolfia species in the southern Western Ghats were observed to get an insight and limitations impacting their fruiting cycles. These species displayed parallel seasonal occurrences in their flowering and fruiting. Over two continuous years, from January to December in 2011 and 2012, monthly observations highlighted discrepancies in the duration of flowering and fruiting, despite the shared seasonal aspects. The peaks and patterns of fruiting varied among these species, demonstrating differences in key factors like fruiting duration, peak times, single/double fruit ratio, and seed purity. Moreover, it was observed that annual precipitation influences the flowering and fruiting behaviors of Rauvolfia.
研究人员观察了西高止山脉南部五个 Rauvolfia 物种的结果模式,以深入了解影响其结果周期的因素。这些物种的开花和结果呈现出平行的季节性。在 2011 年和 2012 年连续两年(1 月至 12 月)的月度观察中,尽管有共同的季节特征,但开花和结果的持续时间却存在差异。这些物种的结果高峰和模式各不相同,显示出结果持续时间、高峰时间、单果/双果比例和种子纯度等关键因素的差异。此外,研究还发现,年降水量会影响豚草的开花和结果行为。

Date palm seeds (Phoenix dactylifera L.) are known to contain phenolic compounds that have the potential as natural photoprotective agents. Phenolic compounds extracted by solvent are suitable for the level of polarity. This study aims to determine the compounds, the value of Sun Protecting Factor (SPF), and the difference in the SPF value of ethanol extract of date palm seeds and their fractions (n-hexane fraction, ethyl acetate fraction, and residue fraction). This research is in two stages. It’s the screening stage and the photoprotective test with the spectrophotometric method. This data was analyzed to descriptive qualitative and photoprotective data with graphed prism 8. In this study, the ethanol extract, ethyl acetate fraction, and residue fraction contained phenolic and terpenoid compounds, and the n-hexane fraction contained steroid compounds. Ethanol extract, ethyl fraction, and residue have sunscreen activity, with SPF values ​​of 3.376±0.15; 6, 13±1, 2; and 3.14±0.08. While the n-hexane fraction with an SPF value of 0.512 ± 0.09. The highest SPF value in the ethyl acetate and n-hexane fractions did not meet the photoprotective SPF range. Phenolic compounds as sunscreens. The data analysis showed a significant difference between the ethanol extract, ethyl acetate fraction, residue fraction, and n-hexane fraction of date palm seeds.

The present research was taken to formulate bacterial consortium as whole cell biocatalyst for retting of dry jute ribbons. The bacteria were obtained from different sources of jute retting water, enriched on nutrient broth medium. Microbial consortium was constructed from 7 (seven) selected isolated bacteria to become 7 (seven) combination culture which exhibited remarkable retting efficacy due to the induction of different enzymes activities. The enzymatic as well as biochemical activity of these bacteria were tested. The strains were selected based on the criteria that they were able to display good zone of inhibition. Formulations showed good potential as candidates for microbial consortium. In the two combination treatment with water (5 ml), microbial consortia of (10DTW2b+OMPW4b), (10DTW2b+4DTW7b) and (OMEW4b+10DTW2b) were found better for all the cases. Again, in three combinations treatment with water (5 ml d.H2O), fineness, brightness and smoothness/softness, all were found higher in microbial consortia of (3PRRF5b+4DTF1b+10DTW2b), which is a unique findings. This research is on-going and need to optimize these consortiums with different parameters and also carry out retting analysis.

This study was conducted to evaluate parity order on milk yield and milk components and calving interval of Baggara cattle as affected by parity in West Kordofan State, Sudan. 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. Results showed a significant differences (p<0.05) between different parities order for calving interval, that short days of calving interval scored by primiparous parities (10.04 months) and long days by 4th parities (13.17month). In conclusion, Baggara cows that depended on natural grazing reached its peak milk production in third parity with considered that the main purpose of these animals for meat production.
本研究旨在评估产次顺序对苏丹西科尔多凡州Baggara牛产奶量、奶成分和产犊间隔的影响。48头牛是从巴格加拉牛群中挑选出来的。称重后按胎次顺序分为A、B、C、D四组,每组12头奶牛。方差分析采用F检验,均值分离采用Duncan’s multiple range test (DMRT)。所有的牛都是自然放牧饲养的。结果表明,胎次顺序对日产奶量、月产奶量和总产奶量影响显著(p<0.05)。产奶量随着产价的提高而增加。第三胎产奶量高(p<0.05),月产奶量为668.47 kg,月产奶量为133.73kg,日产奶量为4.49kg。结果不同胎次泌乳1、3个月乳成分差异显著(p<0.05),第2胎和第3胎泌乳1个月脂肪率较高(分别为6.21和6.26)。结果表明,胎次数对产犊至初发情天数和妊娠天数有显著影响(P<0.05)。初产奶牛发情天数较短(56.19±8.72 d),受胎天数对胎次顺序有显著影响(P<0.05)。结果显示,不同胎次产犊间隔顺序差异有统计学意义(p<0.05),第一胎产犊间隔天数短(10.04个月),第四胎产犊间隔天数长(13.17个月)。综上所述,依靠自然放牧的Baggara奶牛在第三胎达到产奶量的峰值,认为这些动物的主要目的是生产肉类。

Stem rust caused by Puccinia graminis f.sp. tritici is one of the major biotic constraints of wheat production. 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.
小麦锈菌引起的茎锈病。小麦小麦是制约小麦生产的主要生物之一。该病可造成大量数量和质量上的产量损失,但埃塞俄比亚关于该疾病系统的大部分工作侧重于硬粒小麦数量上的产量损失。这项工作是在2015/16和2016/17主要和淡季期间在Debre Zeit农业研究中心进行的。因此,本研究的目的是量化由于茎锈病造成的粮食产量损失,并评估埃塞俄比亚种植的改良硬粒小麦品种的病害参数、粮食产量和物理品质参数之间的关系。采用不同优势茎锈病小种混合进行人工接种。用杀菌剂处理和未处理的地块分别作为保护地块和未保护地块。每隔10 d记录疾病严重程度,计算疾病进展曲线下面积(AUDPC)、终末严重程度、感染系数。被试品种的病害严重程度不同,平均值为6.7 ~ 76%。在Hitossa, Utuba(1225.7, 585.9)上检测到较高的疾病进展曲线下面积(AUDPC)。而产量损失的最低值记录在CVS上。Mangudo和Utuba的产量损失平均值分别为40.2%和44.8%。易感品种Hitosa的产量损失最高,平均为70%。测定了产量损失与AUDPC值、终茎锈病严重程度、侵染系数和侵染率之间的相关系数。各疾病参数间存在较强的相关系数(r=0.72 ~ 0.99)。试验品种的产量、百升重、千粒重与病害参数也存在较强的负相关(r= -0.53 ~ -0.81)。目前的研究表明,在硬粒小麦茎锈病中应用Rex Duo可以最大限度地减少产量损失。因此,在埃塞俄比亚,由于农民手中的大多数硬粒小麦品种对易感品种Pgt有中度易感,因此用杀菌剂支持已发布的硬粒小麦品种是最相关的问题。

Mango is the crucial fruits for home consumption and playing a significant role in the local economy as a means of earning livelihoods for millions of farmers, creating jobs and generating foreign currency in Ethiopia. Homosha woreda’s which is found in Assosa zone of Benishangul gumuz regional state western part of Ethiopia is potential in fruits production; mainly avocado, mango and papaya are the dominant sub-tropical fruits in the woreda’s. 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. Random sampling method and quantitative and qualitative data type has been employed for data collection. 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’.
芒果是家庭消费的重要水果,在当地经济中发挥着重要作用,是数百万农民谋生、创造就业机会和创造外汇的一种手段。在埃塞俄比亚西部Benishangul gumuz地区州Assosa地区发现的Homosha wooreda在水果生产方面具有潜力;牛油果、芒果和木瓜是主要的亚热带水果。然而,目前由于一些制约因素的存在,农民并未从中受益,水果的产量和生产力不时下降。因此,本研究试图评估芒果在世界上的生产限制。数据收集采用随机抽样方法,采用定量和定性两种数据类型。因此,从90个随机选择的芒果生产家庭中收集数据,这些家庭来自三个Kebeles,即Algela, Dareselam和Ashura。通过焦点小组讨论和关键信息者访谈来组织定性数据类型。结果表明,病虫害、鸟害、土地短缺、信贷不足、投入价格高、知识有限、种子质量差和杂草是制约芒果生产和生产力的核心因素。因此,政策制定者应该鼓励研究人员发布芒果的抗病虫害品种,加强推广服务,提高小农的知识和技能,发展努力应该工作和参与提供改良作物品种,投入交付,支持研究和开发应该集中在改善农民的生计和经济上。

A field experiment was conducted with a view to test the efficacy of Tricho-composts and integration of Tricho-composts, poultry refuse (PR), neem oilcake (NOC), saw dust burning (SDB) with chemical nematicide Furadan 5G (Carbofuran) for controlling root knot nematode of country bean through which growers will be benefited. The root-knot nematode infested soils were treated with Tricho-compost-1 @ 2 kg/pit, Tricho-compost-2 @ 2 kg/pit, Tricho-compost-1 @ 2 kg/pit + Furadan 5 G @ 20 g/pit, Tricho-compost-2 @ 2 kg/pit + Furadan 5 G @ 20 g/pit, poultry refuse @ 5-6 kg/pit + Furadan 5 G @20 g/pit , neem oil cake @ 500 g/pit + Furadan 5 G @ 20 g/pit and saw dust burning + Furadan 5 G @ 20 g/pit. It was revealed that all the treatments performed well in reducing root-knot nematode infestation and increasing plant growth and yield country bean compared to farmers’ practices. Among the treatments, integration of poultry refuse with Furadan 5G or Trichoderma based bio-fungicides Tricho-composts with Furadan 5G or neem oil cake with Furadan 5G are the best treatments in reducing root-knot nematode infestation and increasing plant growth as well as yield of country bean. Soil treatment with only Tricho-composts or integration of saw dust burning with Furadan 5G also performed better in reduction of root knot nematode disease and increasing plant growth as well as yield of country bean.
