Plant diseases are among the major factors affecting the yield of wheat, especially rust diseases have historically been one of principal biotic production constraints in the world. Among the three main rusts affecting wheat, yellow rust, caused by Puccinia striiformis f. sp. tritici, and Stem rust caused by Puccinia graminis f. sp tritici are the most important disease in most wheat growing areas of Ethiopia. There are a limited number of resistant varieties available and new pathotypes that overcome the most widely deployed genes have arisen. The development of improved varieties of bread wheat (Triticum aestivum L.) has always remained a focal point for wheat breeders. Therefore, the purpose of this study was to select genotypes with good agronomic performance that have high grain yield and yield component with better rust resistance especially for stripe and stem rusts which are the major diseases in Ethiopia and to recommend the best genotypes to be released as new varieties and as an initial material in breeding. Twenty-Eight genotypes with two checks were evaluated in consecutive two years. From the twenty-eight tested genotypes almost all genotypes except one (ETBW9589) showed higher grain yield than the two standard checks (Kingbird and Ogolcho). But for the case of both rust diseases as AUDPC and CI showed that tested genotypes were exhibited different reaction responses, if we see one genotypes as an example ETBW9578 had the highest grain yield and good for yellow rust but as AUDPC showed it is very susceptible reaction response for stem rust. Generally phenotypic variation was observed for infection types, level of severity and reaction response for both diseases of the 28 tested elite bread wheat genotypes and the two standard checks. Reaction response for stem rust exhibited from susceptible (S) to Moderately resistance-moderately susceptible (M) and from immunity (0) to moderately resistance (MR) for the yellow rust. Around nine genotypes had good performance for all parameters; for grain yield and yield components and also for both rust diseases. The results of current study indicated that the genotypes had diversity regarding resistance reaction, ranging from complete resistance to susceptible. Most of the evaluated genotypes exhibited moderate resistance (MR) to moderately susceptible (MS) reactions under high disease pressure.
植物病害是影响小麦产量的主要因素之一,特别是锈病历来是世界上主要的生物生产制约因素之一。在影响小麦的三种主要锈病中,由小麦条锈病引起的黄锈病和由小麦锈病引起的茎锈病是埃塞俄比亚大部分小麦产区最重要的病害。现有的耐药品种数量有限,并且出现了能够克服最广泛部署的基因的新病型。面包小麦(Triticum aestivum L.)良种的开发一直是小麦育种工作者关注的焦点。因此,本研究的目的是选择农艺性能好、产量高、产量成分抗锈病能力强的基因型,特别是对埃塞俄比亚的主要病害条锈病和茎锈病,推荐最佳基因型作为新品种发布,并作为育种的起始材料。连续两年对28个基因型进行两次检查。在28个基因型中,除1个基因型(ETBW9589)外,几乎所有基因型的籽粒产量均高于2个标准型(Kingbird和Ogolcho)。但对于两种锈病,AUDPC和CI显示,所测基因型表现出不同的反应反应,如果我们以其中一种基因型为例,ETBW9578的产量最高,对黄锈病很好,但正如AUDPC显示的那样,它对茎锈病非常敏感。检测的28种优质面包小麦基因型和两种标准检查在两种疾病的感染类型、严重程度和反应反应方面普遍存在表型变异。茎锈病的反应反应从敏感(S)到中等抗性-中等敏感性(M),从免疫(0)到中等抗性(MR)。约9个基因型在所有参数上表现良好;对粮食产量和产量组成部分,以及对两种锈病。目前的研究结果表明,基因型在抗性反应方面具有多样性,从完全抗性到易感。大多数被评估的基因型在高疾病压力下对中度易感(MS)反应表现出中度抗性(MR)。

This review discusses about laboratory soil analysis and soil mineral management in different Organic farming. The objective of this review were laboratory mineral soil analysis and soil mineral management in organic farming was to draw together all the available relevant research findings in order to develop the knowledge and expertise of organic advisers and thereby to improve soil management practice on organic farms. There are several methods available for measuring total N in soils, mineral N in soils and mineralization potential. Chemical extractions which aim to establish the pool of nitrogen to plants include the use of potassium salts, K2SO4 to extract inorganic and labile organic N pools. Soil P tests are commonly used to assess soil nutrient availability and to assist in fertilizer recommendations. Available K measured by ammonium nitrate gave a good indication of the plant available K in soil; crops showed a response to increasing available K and continued cropping caused a decline in the pool of available K in soil. Soil analysis based on chemical analysis is a snapshot of nutrient pools. It is normally reported in mg/l of soil. Soils are sampled and analysed and digital maps provided to the farmer. This then allows targeted use of inputs to correct nutrient deficiencies or acidity. While this is primarily used in conventional farming for fertiliser application it is now also being used increasingly in organic farming.
本文就不同有机耕作方式的室内土壤分析和土壤矿物质管理进行了综述。本综述的目的是有机农业中的实验室矿物土壤分析和土壤矿物管理,旨在汇集所有可用的相关研究成果,以发展有机顾问的知识和专业知识,从而改进有机农场的土壤管理实践。目前有几种测量土壤全氮、矿质氮和矿化潜力的方法。以建立植物氮库为目的的化学提取包括利用钾盐、K2SO4提取无机氮库和不稳定有机氮库。土壤磷试验通常用于评估土壤养分有效性和协助肥料建议。硝酸铵测定的速效钾能很好地指示土壤中植物速效钾的含量;作物对速效钾的增加表现出响应,而连作导致土壤速效钾库的下降。基于化学分析的土壤分析是养分池的快照。通常以毫克/升土壤为单位报告。对土壤进行采样和分析,并向农民提供数字地图。这样就可以有针对性地使用投入物来纠正营养不足或酸度。虽然它主要用于传统农业施肥,但现在也越来越多地用于有机农业。

The objectives were to determine the concentrations of herbicide residues in soil and different varieties of rice (Oryza sativa L.) and to compare the levels with allowable limits set by WHO/FAO. Four varieties of rice samples (Narica 1, Marica 2, De-gold and Faro 44 were collected from Zabarmari and Bulamari agricultural locations for the determination of herbicide residues. Extraction and cleanup of the samples were carried out using standard analytical procedures. The levels of the studied herbicide residues were determined using Agilent 7890A GC/MS. From the results of the study, it was observed that paraquat and butachlor are the most dominant used herbicides in the study area due to their higher concentrations in the soil and rice samples. The concentrations of all the studied herbicides were significantly higher in the soil samples as compared to the rice samples. The concentrations of all the herbicides in the soil samples were observed to be higher at depth of 0-10cm, while the lowest concentrations were detected at the depth of 20-30 cm. The study clearly indicates that some of the studied herbicide residues in the rice samples were significantly higher than the WHO and FAO maximum residue limits (MRLs) and acceptable daily intake values (ADIs). Hence, this high values of residues of herbicide call for strict vigilance and constant monitoring in other to protect further contamination of the cultivated rice by herbicides.
目的是确定土壤和不同品种水稻(Oryza sativa L.)中除草剂残留的浓度,并将其水平与世卫组织/粮农组织规定的允许限值进行比较。在Zabarmari和Bulamari农业地点采集了4个水稻品种(Narica 1、Marica 2、De-gold和Faro 44)进行除草剂残留测定。样品的提取和清理使用标准分析程序进行。采用Agilent 7890A气相色谱/质谱法测定所研究除草剂残留量。从研究结果来看,由于百草枯和丁草胺在土壤和水稻样品中的浓度较高,因此它们是研究区使用最多的除草剂。所有除草剂在土壤样品中的浓度均显著高于水稻样品。土壤样品中所有除草剂的浓度在0 ~ 10cm处最高,在20 ~ 30 cm处最低。该研究清楚地表明,所研究的水稻样品中的一些除草剂残留明显高于世卫组织和粮农组织的最大残留限量(MRLs)和可接受的每日摄入量(adi)。因此,除草剂的高残留量需要在其他方面保持高度警惕和持续监测,以防止除草剂对栽培水稻的进一步污染。

Tea (Camellia sinensis) is one of the most widely consumed beverages in the world. Tea extracts are source of polyphenols, which are antioxidant components. Green tea phenolic compounds are predominately composed of catechin derivatives, although other compounds such as flavonols and phenolic acids are also present in lower proportion. Camellia sinensis is commonly known as Tea which is most consummated beverage in the world. The diversify properties of the C. sinensis encourage us for new research. There are lots of finding in process on the tea. And there are some positive aspects also found. Present review is an attempt to summarize the various pharmacological effects particularly anti cancer and antioxidant activity may be a powerful tool for future era. In this whole study we can see how much tea is beneficial and may be it will prove a good tool for better treatment option.
茶(Camellia sinensis)是世界上消费最广泛的饮料之一。茶提取物是多酚的来源,多酚是抗氧化成分。绿茶酚类化合物主要由儿茶素衍生物组成,尽管黄酮醇和酚酸等其他化合物也以较低的比例存在。茶树(Camellia sinensis)俗称茶,是世界上最完美的饮料。中华香椿的多样性促使我们进行新的研究。在茶叶的加工过程中有很多发现。同时也发现了一些积极的方面。本文综述是试图总结各种药理作用,特别是抗癌和抗氧化活性,可能是未来时代的有力工具。在整个研究中,我们可以看到多少茶是有益的,也许它将被证明是一个更好的治疗选择的好工具。

The effect of fermentation using Lactobacillus fermentum (Lactic acid bacteria) on the nutritional content, anti-nutrient quality of sorghum (samsorg 17) was investigated. Sorghum sample was subjected to three days (72 hours) submerged fermentation during which the Lactobacillus fermentum was inoculated using 0.5 Mcfarland standard. pH and TTA was recorded after every 12 hours though out the 72 hours of the fermentation. There was decrease in pH with increase in TTA as the fermentation time progresses. The result of the proximate analysis revealed a marginal increase in percentage protein content for fermented sorghum sample (7.89 to 11.50%). There was increase in moisture content and decrease in carbohydrate, ash content and fat contents of the fermented sorghum sample. Results from this research also showed significant reduction in anti-nutritional content which are tannin and phytate. Fermentation has modified the nutritional quality and anti-nutritional quality of sorghum and this has greatly improved the nutrient content of the sorghum.
研究了发酵乳杆菌(Lactobacillus fermentum,乳酸菌)对高粱(samsorg 17)营养成分和抗营养品质的影响。高粱样品进行3天(72小时)的深层发酵,期间以0.5麦克法兰标准接种发酵乳杆菌。在72小时的发酵过程中,每12小时记录一次pH和TTA。随着发酵时间的延长,pH值降低,TTA含量增加。近似分析结果表明,发酵高粱样品的蛋白质百分比含量略有增加(7.89 ~ 11.50%)。发酵后的高粱样品水分含量增加,碳水化合物、灰分和脂肪含量降低。这项研究的结果还表明,抗营养成分,即单宁酸和植酸显著减少。发酵对高粱的营养品质和抗营养品质进行了改性,使高粱的营养成分含量大大提高。

The Ethno-medicinal studies have been carried out for the first time in Charmang, Tehsil Nawagai, district Bajaur, Khyber Pakhtunkhwa (KP), Pakistan. In this project a total of 64 medicinal plants belonging to 39 families and 58 genera and species have been documented, which are being used by the local communities for the treatment of different human sicknesses. Among 64 plant species, 58 medicinal plants species were found as compared with the 12 earlier published articles. This study mainly focused to protect the world’s cultural tradition and to document the importance of medicinal plants present in the research area. A complete data has been established on the general and worldwide uses of the projected study to find out new possible species for further studies. A general field surveys was arranged in the desire area, which was based on semi-structured meetings of 135 local sneaks. To assess the exact herbal knowledge, the data were investigated using quantifiable Ethno medicinal records as RFC (Relative Frequency Citation) and UV (Use Value), separately. The local interviewed peoples used 64 plant species belonging to 58 genera in 39 families, mainly Lamiaceae , Rhamnaceae and Solanaceae . The type of most common diseases (25%) was Respiratory diseases (Asthma, Throat infection, Cough etc.). The present study was emphasized based on ironic herbal knowledge to know the novel findings of medicinal plants in district Bajaur, KP, Pakistan which could be a standard use for upgrading the knowledge in terms of plant phytochemistry, pharmacology and biological activities for the efficiency and safety of medicinal plants.
首次在巴基斯坦开伯尔-普赫图赫瓦(KP)巴焦尔地区的Charmang、Tehsil Nawagai进行了民族药物研究。在这个项目中,共记录了64种药用植物,属于39科58属和种,这些植物被当地社区用来治疗不同的人类疾病。在64种植物中发现58种药用植物,而之前发表的文献只有12种。本研究的重点是保护世界文化传统,并记录研究区药用植物的重要性。已经建立了一个完整的数据,关于一般和世界范围内使用的预测研究,以发现新的可能的物种进行进一步的研究。根据135名当地偷窃者的半结构化会议,在愿望区域安排了一般的实地调查。为了评估确切的草药知识,使用可量化的民族医药记录分别作为RFC(相对引用频率)和UV(使用价值)进行调查。当地被采访者利用的植物种类64种,隶属于39科58属,以兰科、鼠李科和茄科为主。最常见的疾病类型(25%)是呼吸系统疾病(哮喘、咽喉感染、咳嗽等)。本研究以讽刺植物知识为基础,了解巴基斯坦KP巴焦尔地区药用植物的新发现,可作为提高药用植物的植物化学、药理学和生物活性方面知识的标准用途。

A pot experiment was conducted to evaluate the effect of arbuscular mycorrhizal fungi (AMF) inoculation on different varieties of Cicer arietinum L. (Chana Punjab 2008, Chana Dasht and Chana bakar 2011). The experiment was carried out in completely randomized block design (RCBD) with AMF treatments and replications three times repeated under natural condition during Rabi season 2014-2015 at Department of Botany Bacha Khan University Charsadda, Khyber Pakhtunkhwa-Pakistan. The pots were filled with processed soil and each pot having 4Kg of phosphorus deficient soil (1.43 mg kg-1). Size of each pot (23cm x 19.5cm). Some pots were inoculated with arbuscular mycorrhizal fungi and twenty seeds of chickpea were sown in each pot. The results show that arbuscular mycorrhizal fungi inoculation significantly increased proximate composition in Chickpea verities as compared to non-inoculated plants. Inoculated plants performed better when compared with control plants. Similarly it is also proved that Chickpea verities are more dependent on mycorrhizal inoculation under P-deficient condition for better survival.
通过盆栽试验,研究了接种丛枝菌根真菌(AMF)对不同品种金丝菊(Chana Punjab 2008, Chana Dasht and Chana bakar 2011)的影响。实验采用完全随机区组设计(RCBD),于2014-2015年拉比季节在巴基斯坦开伯尔-普赫图赫瓦省查尔萨达市巴查汗大学植物系进行,AMF处理和自然条件下重复3次。盆内填满处理过的土壤,每盆含4Kg缺磷土壤(1.43 mg kg-1)。每个锅的尺寸(23厘米x 19.5厘米)。在部分盆栽中接种丛枝菌根真菌,每个盆栽播种20颗鹰嘴豆种子。结果表明,与未接种的植株相比,接种丛枝菌根真菌显著提高了鹰嘴豆植株的近似值组成。接种植株比对照植株表现更好。同样也证明了鹰嘴豆品种在缺磷条件下更依赖菌根接种以获得更好的存活率。
