Abstract: The study was conducted at Threekebeles namely Tenkaka, Umbulowacho and Kajima kebele in Hawassa Zuria woreda, Sidama Regional state, Ethiopia with the objective of to increase improved poultry breeds option to resource small scale farmers’ condition in the region by demonstration and evaluating production performance of Lohman Layers breed. Thirty (30) Participant farmers were selected purposively from three kebeles (10 farmers from each kebele) on the basis of willingness to construct poultry house; to cover all the associated package costs and record the required data. Under each household 30 pullets of Lohmann brown chicken were distributed that purchased from Debre Zeyt poultry Multiplication and Dissemination center. Before the distribution of pullets training was given for those farmers about general management and husbandry of breeds essential data like body weight at monthly basis, mortality and cause of mortality, age at the start of egg lay, body weight at the start of egg lay, weight of egg at the egg lay start has been collected and spread out on the Microsoft office excel 2007. SPSS (version 20.0) was used to analyze data. The survivability of chickens under farmer’s level averagely 89.3% up to the age of 22th week or on set of egg lay observed. On averagely 2.8% mortality rate was occurred at 12th and the main causes of mortality was the disease and predatory. Generally 10.7% mortality rate or 89.3% survival rate was observed in this study. The average weight gain also recorded using sensitive balance to evaluate growth performance. As a result, there was increasing trend of weight gain starting from initial to onset of egg production. So, maximum average body weight gain of Lohmann brown chickens was 1.32 kg at 22nd week. Similarly, average egg weight has been increased averagely 54.1 gm around 22nd week of age. Finally, the Lohmann Brown chickens in all aspects of production and productivity were feasible to enhance family nutrition and income generating aspects, as a result has indicated on this study at Hawassa Zuria Woreda or mid land area and the same investigation should be done in other ecologies specially high and low lands of the region.

Abstract: Acute Respiratory Infections (ARI) are, after malaria, the second most common cause of consultation of children in health facilities in Côte d'Ivoire. Viral etiology points to Respiratory Syncytial Virus (RSV) as the primary cause of these acute respiratory infections. In order to better assist health workers in diagnosing the virus, a study on the epidemiology, seasonality and clinical signs associated with RSV acute respiratory infections was conducted over four consecutive years. During these years, nasopharyngeal samples were collected from 5648 children aged 0-5 years, in different geographical areas of the country, following a survey form for analysis by real-time PCR, to detect the virus and describe its epidemiological characteristics. Our results revealed 564 (9.98%) RSV positive children. A number of 181 (32.09%) were positive in inpatients, and 383 (67.91%) in outpatients. The 0-12 month age group was the most affected with 51.95% of positive cases. Cumulative monthly RSV activity for the 4 years of the study was relatively lower during the months of January to March and higher during the months of May to September. This distribution of RSV was superimposed on rainfall during these study years. Our work has also linked RSV positivity to the presence of clinical signs, including fever, cough, diarrhoea and vomiting. These results give scientific tools to health personnel to better orient their diagnosis and also a better rational use in the prescription of medication, notably the stopping of unjustified antibiotic therapy.

Abstract: Bambara groundnut (Vigna subterranea L. Verdc), a neglected and underutilized legume is one of the main source of plant protein for poor families in tropical Africa, and is capable of contributing to increasing food production in Africa. This present study aimed to see how bambara groundnut respond to induced water stress during the flowering stage. The research was carried out at the Teaching and Research Farm of The Federal College of Agriculture, Akure (FECA), Ondo State, south west zone in Nigeria. The experiment was a split-plot experiment laid out in a Completely Randomized Design (CRD) with three replications during the late planting season of 2020. Data were collected on Plant height, Number of branches, Number of Leaves, Terminal Leaf Length, Terminal Leaf Width (cm), Biomass, Wet Pod Weight/Plant, Dry Pod Weight/Plant, Pod Length, Pod Width, Number of Pods/Plant, Seed Length, Seed Width, Number of Seeds/Plant, and Seed Weight/Plant. Result showed that among the growth parameters evaluated, Number of leaves and branches were significantly influenced by the various induced stress conditions and the control plot recorded the most significant difference. Among the accessions; accession B8 recorded significantly higher number of leaves across the weeks, while accession B1 recorded significantly higher number of branches in week 4 and 12 whereas, B6 recorded against week 8. The interaction C*B8 recorded significantly higher number of leaves and branches at week 4, whereas at week 8 and 12, the interaction DRT*B1 recorded significantly higher number of leaves for both weeks, while C*B6 with at week 8 and at week 12 recorded significantly higher number of branches. For the yield, the result obtained showed that the control significantly (p ≤ 0.05) improved dry seed weight and other yield components (number of pods/plant, number of seeds/plant) of bambara groundnut. The bambara groundnut accessions exhibited differential yield potential. The highest wet and dry seed weight/plant was obtained in the B4 followed by the B7 and lowest is the B10. The B4 out-yielded the other accessions, indicating its high adaptability and suitability to the various induced stress conditions at the flowering stage of the bambara plant.

Abstract: Multi-locational trials are critical for establishing stable and adaptable genotypes across different geographic areas prior to considering commercial release. The stability and adaptation of 20 tropical maize hybrids in environments infected with Northern leaf blight disease were assessed using 12 parametric and 14 nonparametric parameters across five environments. The purpose of this research is to estimate the genotype-environment interaction (GEI) for grain yield in selected maize genotypes and to identify associated stability factors to aid in the rationalization of stability analysis in Multi-Environment Trial (MET) data used in breeding programs. Except for De Kroon and Van der Laan (1981), both the combined ANOVA and nonparametric tests of GEI showed significant differences across hybrids, as well as significant crossover and non-crossover interactions. This suggests differential genotypes responses to the test environments. Spearman correlation analysis revealed significant differences between many nonparametric and parametric parameters, indicating that the two may be utilized interchangeably. Additionally, the correlation matrix and principal component analysis results from parametric and nonparametric parameters demonstrated their potential to assess the responses of maize genotypes to changing environments. G13 and G20 appeared most phenotypically stable with associated high mean yield based on the high values expressed by most parametric and nonparametric parameters.

Abstract: Soil salinity is currently considered as a major environmental problem. This issue is accentuated by climate change, especially in arid and semi-arid regions. In these areas, drought and high level of salt in soils and irrigated waters are the main abiotic factors limiting plant growth and productivity. On the other hand, rapid population growth and reduction of arable land are major factors that could affect food security. Regarding salt tolerance, most crop plants show sensitivity to high salt levels, but it differs strongly between species and slightly between cultivars within the same species. Cucumber (Cucumis sativus L.) is an important economic crop and is sensitive to salinity. To enhance cucumber performance and resistance to high levels of NaCl, different strategies can be employed, In recent decades, an increased research interest has been devoted to develop new strategies to overcome the deleterious effects of salinity on cucumber plants by using molecular markers and genetic transformation as tools to generate salinity-tolerant genotypes together with the implementation of some cultural techniques. Among the other strategies currently being used is the exogenous application of biostimulants and bioregulators. In this regard, and in order to improve salt tolerance of cucumber plants, we have discussed here the effect of foliar application of bio-regulators such as silicon, salicylic acid, and ascorbic acid on plant metabolism and yield.
